TORONTO -- A close confidant of Queen Elizabeth I used an obsidian mirror with Aztec origins to contact otherworldly spirits in his occult practices, according to new research.

John Dee was a renaissance polymath during the 16th century who was interested in astronomy, alchemy, and mathematics, Stuart Campbell, an archeology professor at the University of Manchester, said in a press release.

“Later he became involved in divination and the occult, seeking to talk to angels through the use of scryers, who used artefacts - like mirrors and crystals,” Campbell added.

One of those scryers – a tool used to see or predict the future – was an obsidian mirror that has long been suspected of having Aztec origins, but with no records to show how Dee obtained it, it was difficult to prove.

That is until Campbell and a team of international scientists used geochemical analysis to reveal the mirror’s origins.

To do this, they studied four objects currently housed in the British Museum – Dee’s mirror, two other Aztec mirrors, and a polished rectangular obsidian slab.

They then bombarded the mirrors with X-rays, resulting in the objects also emitting X-rays, which allowed the scientists to measure the artifact’s composition. The researchers described these X-rays as “unique fingerprints” that can be compared to other obsidian artifacts to trace the origins of the materials.

According to the findings, published in the journal Antiquity, all four of the obsidian artifacts studied were made from Mexican obsidian exploited by the Aztecs.

Dee’s mirror, specifically, along with another with a similar design, originated from near Pachuca in Mexico.

The scientists said obsidian, an igneous rock occurring as a natural glass formed by rapid cooling of lava from volcanoes, had a spiritual significance to the Aztecs. It was used as part of medicinal practices, as a shield against bad spirits, and to capture souls on its reflective surface.

The rocks’ symbolic value may have made them appealing items for Europeans to collect and bring home as they conquered the Aztecs in the 16th century, the researchers theorized. The mirrors were also often viewed as magical artifacts in Europe at that time too, which may have served as additional motivation.

“The 16th century was a period in which new exotic objects were being brought to Europe from the New World, and opening up exciting new possibilities in the intellectual world of the period,” Campbell said.

The scientists said the Aztec mirrors were “novel and exotic items” that found a place in many early collections in Europe. They suggested stories about the mirrors may have been why Dee chose to include one in his occult practices.

(CNN)An obsidian "spirit mirror" used by a confidant of Queen Elizabeth I is actually a product of the Aztec culture, according to new research. An analysis of the obsidian mirror, made from volcanic glass, and three other similar objects at the British Museum revealed their Mexican origins.

The obsidian mirror with the Elizabeth I connection belonged to John Dee, an adviser of hers from when she became queen in 1558 and through the 1570s. Dee served as the queen's astrologer and also consulted with her on science. This included Dee acting "as an advocate of voyages of discovery, establishing colonies and improving navigation," said Stuart Campbell, study author and professor at the University of Manchester.

"John Dee is a remarkable historical figure, a Renaissance polymath -- interested in astronomy, alchemy and mathematics -- and confidant of Elizabeth I," Campbell wrote in an email. "Later he became involved in divination and the occult, seeking to talk to angels through the use of scryers (those who divine the future), who used artifacts -- like mirrors and crystals."



The obsidian mirror used by John Dee was created by the Aztecs.

While it had been previously suspected that the mirror had been made by the Aztec culture, there were no records accompanying the object to show how it came into Dee's possession.

A team of researchers used geochemical analysis to target the four obsidian objects with X-rays. This in turn caused the objects to emit X-rays, helping the scientists determine their composition by revealing the elements of the obsidian. In addition to Dee's mirror, they studied two other Aztec mirrors and a rectangular slab of obsidian.

The analysis showed that all four were made using Mexican obsidian. Dee's mirror and a similarly designed mirror were made using obsidian from Pachuca, a city that is a source of obsidian the Aztecs used. The third mirror and the slab are made of obsidian from the town of Ucareo, another obsidian site in Mexico.

A study on the findings published Wednesday in the journal Antiquity.

The researchers estimate that Dee's mirror is about 500 years old, most likely made in the final decades before the Spanish conquest of Mexico in 1521, Campbell said.

"We know that Spanish conquistador Hernán Cortés sometimes commissioned items from Aztec craftsmen so he could send them back to the Spanish court," Campbell said. "So it is even possible that some of the circular mirrors like John Dee's were specially made by Aztec craftsmen at the time of the conquest of the Aztec Empire to send back to Europe."



This figure shows Tezcatlipoca, lord of the smoking mirror, with circular obsidian mirrors on his temple, his chest and his foot highlighted.

While researchers haven't been able to pinpoint the obsidian mirrors' intended use in Aztec culture, depictions remain that show circular obsidian mirrors made at this time.
"They're shown particularly in drawings of the god Tezcatlipoca, in place of a missing foot, or attached to his chest or head," Campbell said. "The mirrors that have survived may well have actually been attached to statues of the god. Tezcatlipoca was the god of divination and providence, amongst several other things, and the obsidian mirrors were probably much more than simply symbols of power -- they also seem likely to have been used for divinatory purposes."

Tezcatlipoca's name also means "smoking mirror."
The Aztecs believed that obsidian had spiritual significance, and it was used in their medicinal practices, as well as a way to ward off bad spirits or even capture souls by using the reflective nature of the volcanic glass.
Items of such significance to the Aztecs would have been intriguing to the Europeans exploring Mexico.



These are Aztec depictions of the mirrors.


"The 16th century was a period in which new exotic objects were being brought to Europe from the New World, and opening up exciting new possibilities in the intellectual world of the period," Campbell said.

Dee, the first person known to use the term "British Empire," would have been fascinated by the idea of the mirrors if he heard stories of how the Aztecs used them, Campbell said. Dee had an interest in the occult early on, and once he obtained the obsidian mirror, he used it to try communicating with spirits, according to the study.


This is a portrait of John Dee from 1594.

Understanding the origins of the obsidian mirror can help researchers retrace the paths of such objects from a time when appropriation occurred frequently.

"To me, it helps us understand something of the way in which the European voyages of discovery and engagement with other parts of the world, often through disastrous conquest, was matched by intellectual attempts to understand how the world worked," Campbell said. "Novel artifacts brought back to Europe from the Americas entered collections of nobility and of intellectuals, and were used and appropriated in the efforts of people, who -- like John Dee -- saw themselves as scientists, to understand the world in new ways."

During his time as Elizabeth's confidant and adviser, she visited him several times at his home, Campbell said. Dee was considered to be one of the reigning intellectuals of that period; he had the largest library in England and one of the greatest in Europe, Campbell said.

"The surviving record of (the library) is actually of major importance in understanding 16th- and early 17th-century intellectual thought," Campbell said.

To Dee, the supernatural was indistinguishable from science. "It may have been his growing interest in those areas of study that gradually undermined his role in the court by the end of the 1570s," Campbell said.

Toxic blend of "trust and power" makes Catholic Church hotbed for systemic child abuse

Issued on: 07/10/2021 -


In the wake of a major child sexual abuse investigation that counted 216,000 victims in France, spanning over seven decades, France 24 is joined by Marc Artzrouni, European Coordinator for SNAP (Survivors Network of Those Abused by Priests). Mr. Artzrouni expressed amazement and gratification that the damning report had such a profound and immediate impact. "I wasn't really expecting such an impact,' admits Mr. Artzrouni, "and I'm really glad the report is reverberating throughout the world and throughout the media." Additionally, he highlights a very disturbing pattern: "Very few countries have been unaffected by this. Very few countries where there is a Catholic presence have been unaffected by this." Offering a little historical perspective, Mr. Artzrouni points out that "this report goes back to the 1950's. It's highly probable that this has been going on for centuries in the Catholic Church."

McDonald's wants to set more ambitious emission reduction goals.

Published 

McDonald’s wants to achieve net zero emissions globally by 2050.

The plans are vague, but the fast-food giant said it aims to reduce its emissions across restaurants, offices, and supply chains, according to a company press release today (Oct. 4). The details on how it will update targets will be released next year, as it works with Science Based Targets initiative (SBTi), a nonprofit that works with the private sector on setting emission targets, McDonald’s said in an email to Quartz.

Five of the six biggest fast-food chains announced this year they will set, or have set, science-based targets to reduce their emissions, up from just two companies last year, according to a report this year from investors network Ceres and nonprofit Farm Animal Investment Risk & Return (FAIRR). McDonald’s announcement follows a similar pledge from from Yum Brands, which owns KFC, Pizza Hut, and Taco Bell, which also aims to achieve net-zero emissions by 2050. Chipotle, Domino’s, Restaurant Brands International (owner of Burger King and Popeyes),  and Wendy’s have also made pledges. Restaurant Brands’s global target has not been approved yet by SBTiNet-zero means the amount of greenhouse gas the companies produce are no more than the amount reduced via increased energy efficiency and actions such as planting trees.

McDonald’s also said it is working on implementing local solutions in renewable energy, regenerative farming, and sustainable packaging, according to the press release. For instance, the company said it plans to open a new burger restaurant in the UK this November to test solutions for reducing energy and water use, which will be a blueprint for new McDonald’s sites in the future. The restaurant will feature furniture made from recycled or certified materials by 2023 as well as packaging made with renewable, recycled, or from certified sources by 2024.

In recent years, the fast-food chain has made efforts to reduce its emissions. In 2018, McDonald’s became the first global restaurant company to set a so-called science-based target—or to formally outline how it will adopt greenhouse global emissions—approved by SBTi, to help keep global temperature from rising above 1.5%. The company also recently announced it plans to cut plastic out of Happy Meals toys and packaging  by the end of 2025.

How the food industry is combatting climate change

In the US alone, around 85 million adults, or one-third of the population over 20 years old, consumes fast food daily.

In recent years, activist investors and nonprofit groups have stepped up pressure on fast-food companies to better manage their climate and water scarcity and to set greater reduction targets.

To meet its targets, McDonald’s has a lot of work to do. It’s one of the biggest buyers of food in the world and about 80% of its total emissions come from its supply chain, in particular, its use of beef, chicken, dairy, and other proteins. The company said it has been working with partners to develop more sustainable farming practices. Animal agriculture produces around 15% of global greenhouse gas emissions, driven by emissions from livestock and feed; meanwhile, feed for livestock is responsible for a third of annual global water consumption, according to sustainability groups.

Fast food companies still need to address water scarcity and pollution risks in their meat supply chains, according to Ceres and FAIRR. Efforts on how they plan to assess these risks have been limited in scale and scope, the sustainability advocates said. There has also been slow progress on disclosing their analysis of climate risk scenarios, they added.

The costs of climate change on the industry are also becoming more apparent. US livestock producers are facing 30% higher feed costs due to increasing droughts as well as storms damaging their livestock and land, according to the report, which has a direct impact on the farmers and various vendors that are vital to producing McDonald’s meals.

    THE MOST PRESSING QUESTION

    How do we get to net zero emissions?

    The question will define the global economy for the next century. The IPCC estimates (pdf) we need to invest at least $1.6 trillion per year through 2050 to put the planet on a safe climate trajectory. We’re spending about 20% of that figure today. And that’s just for the energy sector.  The climate economy means almost every aspect of our global system—agriculture, transportation, energy, construction—will need to be rethought and redesigned to reduce and then remove greenhouse gases from the equation. It’s the greatest challenge, and opportunity, of our time.

California’s offshore industry under fire after oil spill

'This spill should be the end of offshore drilling in California'

Cruising along the panoramic Pacific Coast Highway that hugs the curves of California’s shoreline, it’s the salty sea breeze that typically overtakes you. This week, it’s the stench of crude oil.

The state’s worst oil spill in almost 30 years means crude is washing ashore as “tar balls” or “patties,” a sticky mess that gets caught in the sand. It’s marring some of the world’s most renowned beaches, famed almost as much for the surf as for the multi-million dollar homes that dot the hills overlooking the ocean.


The mucky scene playing out across Southern California’s coastline is reigniting the debate over an offshore drilling industry that once helped make the Golden State one of the most prolific oil-producing regions in the world, churning out more than 1 million barrels a day at its height. Today, the output from old platforms that dot the region’s shores has dwindled to just tens of thousands of barrels a day, and the risk of leaks and oil spills has risen. The disaster has also drawn fresh scrutiny of aging offshore oil and gas infrastructure around the world, built decades ago back before fracking, horizontal drilling and shale made ocean drilling less economic.

The roughly 3,000 (126,000 gallons) barrels of crude that have poured into the ocean near Huntington Beach isn’t just an environmental and economic blow. It has triggered visceral anger and revived questions about why California still has an offshore oil industry at all, five decades after it stopped issuing new drilling permits.

“This spill should be the end of offshore drilling in California,” Julie Teel Simmonds, senior attorney at the Center for Biological Diversity, said by phone from San Diego. “This should be the last catastrophic spill we endure.”

JULIE TEEL SIMMONDS

It’s not just the environmentalists. Both of California’s senators — Dianne Feinstein and Alex Padilla — said the episode underscores the need to block offshore drilling, including through a legislative ban on new leasing off California, Oregon and Washington. The House has already tucked the measure into its version of a multi-trillion-dollar reconciliation bill designed to advance major Biden administration policy priorities.

“This is yet another preventable environmental catastrophe,” but “we have the power to prevent future spills,” Padilla said in an emailed statement.

Many of the famous sandy stretches near Huntington Beach, which has been fighting with Santa Cruz for the nickname “Surf City,” are closed and vacationers are canceling plans.

Shaun Hammon, manager of Ocean Surf Inn and Suites in Sunset Beach, just north of Huntington Beach, said while the “actual physical stuff” hadn’t yet reached the beach closest to the inn as of Monday afternoon, customers are nervous.

“It’s not only an ecological crisis,” said Chad Nelsen, who could smell the oil at his favorites surf spots this week. He serves as the chief executive officer of the Surfrider Foundation, an environmental group headquartered in San Clemente.

“It’s a community, recreation and ultimately, an economic crisis. Once a spill occurs, the toothpaste is out of the tube, the damage is done,” he said.

The spill, from a pipeline owned by a unit of Amplify Energy Corp., comes at a time when California has been aggressively moving to shift away from fossil fuels. Although the first offshore oil wells in the U.S. were drilled just east of Santa Barbara in 1896, it’s been reining in the industry in more recent decades. The state stopped issuing new offshore oil and gas leases after a high-profile spill in 1969 and has taken an increasingly hard line on the sector.

The days of oil production were numbered in California even before the latest leak. Governor Gavin Newsom, who declared a state of emergency late Monday to assist with the response to the spill, has banned the sale of new gasoline-powered cars by 2035 and targeted phasing out fossil fuel extraction by 2045.

“As California continues to lead the nation in phasing out fossil fuels and combating the climate crisis, this incident serves as a reminder of the enormous cost fossil fuels have on our communities,” Newsom said in the statement.

Many of California’s offshore oil rigs have been shut and some dismantled after years of decline. Oil production in federal waters off the U.S. West Coast totaled 13,000 barrels a day in July, down from more than 200,000 barrels a day in the mid 1990s. Closer to shore, in state waters, that total was about 19,000 barrels a day in 2019.

Much of that decline happened after a break in a Plains All American Pipeline LP line near Santa Barbara in 2015 spilled thousands of gallons of crude onto a local beach, prompting the shutdown of multiple production platforms. One, Platform Holly, is currently being decommissioned and its wells plugged, but three others, Exxon Mobil Corp.’s only oil platforms off the California coast, are still maintained, but not operating. The company is trying to get the go-ahead to start them up again.

But even then, California was ranked as No. 7 last year among U.S. oil-producing states (topping for example, Wyoming, which is perhaps more well-known for its crude production).

The offshore production that continues in California may be partly because companies are reluctant to absorb the costs of shutting and decommissioning existing platforms, said Simmonds of the Center for Biological Diversity. The oil that spilled into the sea this week emerged from a pipeline linked to a network of decades-old production facilities.

“Oil and gas companies theoretically put up a sufficient bond to cover decommissioning costs, but they usually are woefully inadequate and many companies just end up declaring bankruptcy, leaving taxpayers to pick up the tab,” she said.

There are other obstacles to cutting back. The state is already facing an enormous squeeze on its electricity grid, with intermittent power from wind, solar and hydro sources proving difficult to manage amid recent bouts of extreme weather. Natural gas prices have soared as California utilities have had to burn more of that fuel.

Disrupting offshore drilling could make the state more dependent on crude imports, said Zachary Rogers, director of global oil service at Rapidan Energy.

“While there will certainly be a passionate reaction to the spill, it’s tough to say whether or not this will materially affect future production in California,” he said.

Even dwindling offshore production for some smaller oil companies makes it worthwhile, and dismantling an aging platform has costs and generates zero profit, said Deborah Gordon, senior principal in the Climate Intelligence Program at the Rocky Mountain Institute. She also pointed to the likelihood of more oil imports into the state if offshore output is curbed.

“It’s a much bigger systemic problem,” she said.

Chris Varcoe: Demise of Canadian Energy Pipeline Association 'really short-sighted,' warns Alberta energy minister

HEY WE ARE PUMPING TAXPAYERS DOLLARS OUT FOR YOUR PR AND YOU DO THIS

'The opposition isn't going to stop just because new crude oil pipelines have been completed and built,' Sonya Savage says

The era of massive oil pipeline projects being pitched in Canada is winding down with the demise of Keystone XL earlier this year.

Does Canada need an organization to advocate for oil and natural gas pipelines if no new significant project proposals are coming down the road?

Aside from the owners, who will speak up for projects now underway or existing ones facing fierce opposition — such as Enbridge’s Line 5, where a new twist unfolded Monday — if the group that represents the sector disappears?

These are questions for the industry to ponder after the Canadian Energy Pipeline Association (CEPA) said Friday it will stop operating at the end of 2021.

It’s clear that leaders of large pipeline companies, including Enbridge, TC Energy and Pembina Pipeline, can speak up for their individual businesses to regulators, policymakers and the public — and they will.

However, that leaves CEPA headed for extinction.

The decision to close comes after Enbridge decided to leave the 28-year-old industry association last fall, with TC Energy and Pembina Pipelines serving notice they would depart by the end of this year.

Alberta Energy Minister Sonya Savage, who previously worked at CEPA and Enbridge before entering politics, was blunt Monday when asked about the decision.

“It’s really short-sighted for these companies to have let the industry association fold because you know we’re going to need it again,” Savage said in an interview.

“You see the attacks and the opposition to major new pipeline projects. Well, that opposition is now targeting existing pipelines … Who is going to be advocating for the industry-wide perspective on that?”

CEPA president Chris Bloomer said the loss of the three large pipeline companies as members created a budget hole that couldn’t easily be filled.

It led to the board’s decision to stop operations by year’s end and the pipeline companies will soon be left to speak on their own behalf.

“My indication from the companies is they want to do it on their own,” Bloomer said Monday.

“And companies like TC and Enbridge, they have the capacity to do that … but the larger companies are changing, too, and their focus is different and that needs to be recognized.”

The companies certainly have the ability to hire lobbyists and experts to ensure their voices are heard in Ottawa.

In a statement, TC Energy said it is a member of various trade associations across North America and, after careful review, decided to not renew its CEPA membership.

The decision also reflects a changing period for the country’s pipeline sector. The era of massive oil pipeline projects being pitched in Canada is winding down with the demise of Keystone XL earlier this year.

While opposition to Enbridge’s Line 3 replacement project continues, the pipeline began to fill up with oil on Friday. Construction on the Trans Mountain expansion is now more than 30 per cent complete.

CEPA started as a technically focused organization that shared information and collaborated on best practices, Bloomer said. With the pipeline battles of the past decade, it shifted into an advocacy role.


But legislative hurdles, low commodity prices, the push to decarbonize, along with ongoing legal and regulatory struggles, have all made it difficult to build new energy infrastructure in North America.


“It’s a sign of the times,” said former TransCanada executive Dennis McConaghy, who has written books about the pipeline sector.


“It’s another voice lost in Ottawa.”

Former TransCanada Corp. CEO Hal Kvisle, who is chair of the Business Council of Alberta, said CEPA played a strong role over the years on technical issues, such as dealing with pipe corrosion and integrity issues.

The pipeline battles in North America today are a different matter.

It's another voice lost in Ottawa
DENNIS MCCONAGH


“The problems are so political and so difficult and of such national interest, I think an organization like (CEPA) would have a very tough time having an impact,” Kvisle said.

The battle over Line 5, an existing pipeline operated by Enbridge, highlights the presence of politics in such matters.

The pipeline ships 540,000 barrels of oil and natural gas liquids per day from Western Canada to Ontario, with the route running under the Straits of Mackinac, moving product through Michigan to Sarnia.

Michigan Gov. Gretchen Whitmer, citing safety concerns, wants to shut it down and revoke an easement granted in 1953 for the line to pass under the straits. The dispute is before the U.S. courts.

Enbridge and the Canadian government are working together, along with the provinces, to ensure the flow of energy to the area isn’t disrupted.

On Monday, lawyers for the federal government officially invoked a dispute settlement provision in a 44-year-old pipeline treaty signed by Canada and the U.S. to prevent authorities from blocking the transmission of oil or gas in transit between the countries.

News of the treaty being invoked came after mediation discussions between Michigan and Enbridge stopped. “Enbridge has continued to participate in the mediation process in good faith and still is hopeful that a negotiated resolution” can keep energy flowing, the company said in a statement.

Savage called Monday’s announcement good news, as discussions were at a standstill and invoking the treaty “needed to happen.” It will take the dispute out of the legal system while the treaty is discussed by the two countries.

As for the end of CEPA, Savage called it a disappointment, noting an industry group can speak with a much broader voice to governments than a single company on key matters such as building or operating existing pipelines.

“The opposition isn’t going to stop just because new crude oil pipelines have been completed and built. It’s going to find something else to oppose and they won’t have that strong voice of the industry association representing the industry as a whole,” she said.

“That is going to be problematic.”

Catalysts found to convert carbon dioxide to fuel

The goal of tackling global warming by turning carbon dioxide into fuel could be one step closer with researchers using a supercomputer to identify a group of "single-atom" catalysts that could play a key role.

Researchers from QUT's Centre for Materials Science, led by Associate Professor Liangzhi Kou, were part of an international study that used theoretical modelling to identify six metals (nickel, niobium, palladium, rhenium, rhodium, zirconium) that were found to be effective in a reaction that can convert  into sustainable and clean energy sources.

The study published in Nature Communications involved QUT researchers Professor Aijun Du, Professor Yuantong Gu and Dr. Lin Ju.

Professor Kou said the research was conducted by modelling the experiments using the National Computational Infrastructure at the Australian National University, looking at how single atoms of the metals would react with two-dimensional pieces of "ferroelectric" materials.

Ferroelectric materials have a  on one face, and  on another, and this polarization can be reversed when a voltage is applied.

In the theoretical modelling, the researchers found that adding the atom of the catalyst metal to the ferroelectric material resulted in converting the greenhouse gas into a desired .

Once the polarity is reversed, the state will be preserved to act as a catalyst in converting the carbon dioxide.

Professor Kou said while single-atom catalysts to be used in reducing carbon dioxide was proposed a decade ago, this research takes the field forward significantly.

"We have designed a special chemical catalyst, it can convert the  CO2 into the desired chemical fuels. The conversion efficiency can be controlled using a feasible approach," Professor Kou said.

"It means we for the first time developed the abilities to speed up or slow down, even switch off the chemical reaction.

"Carbon dioxide is the main reason of  due to the greenhouse effect, to convert it into the chemical fuels is not only important for our environments, but also helpful to solve the energy crisis."

Dr. Ju, first author on the study, said the research work provided a guidance for the design of novel catalysts which could produce significant impacts for the chemical industry.

Professor Kou said the long-term goal in this area of research was to find ways to turning carbon dioxide into clean energy sources.

Professor Kou said the results of this study could eventually lead to a way of adding a coating to engines or industrial systems that would convert  dioxide instead of releasing more of the gas into the atmosphere.

RepAir Carbon realised fuel cell tech could be applied to CO2 capture — now they plan to scale
Mike Butcher@mikebutcher •October 6, 2021



Existing technologies for direct air capture technologies require a lot of heat to remove the CO2, after it’s been absorbed into filters. The process to date has been laborious and often highly energy inefficient. What’s often been missing in the process has been a more efficient way of capturing CO2 in the first place. The key to the whole thing is filters, and it is this aspect that more than one startup has been working on in the last few years.

Israel-based RepAir Carbon has now came up with an approach drawn from the ideas behind fuel cell technology to do just that, and it’s now closed a $1.5 million seed funding round co-led by Counteract and ESIL, with participation from Consensus Business Group, ImpactAssets and other investors. ESIL is a partnership of EDF Renewables, Johnson Matthey and Bazan Group.

RepAir Carbon’s aim is to develop this “cell” approach for what it describes as “modular Direct Air Capture” to capture or store greenhouse gases “at a gigaton scale”. The promise is much lower energy consumption and a less CapEx intensive, modular design based on electrochemistry.

RepAir says it uses an electrical current and a selective membrane to separate CO2 from the air, consuming “up to 3 times less energy for each tonne of CO2 captured without the need for high temperature or significant pressure differentials.”

Amir Shiner, co-founder and CEO of RepAir said: “Direct Air Capture plays a key role in any scenario where global temperature rises less than 2°C. However, today’s solutions are too expensive, energy-hungry, and resource-intensive. We’re working hard to develop a technology with a responsible energy footprint that can be deployed in many more settings. This investment will help us advance and optimize our TRL3 prototype.“

Alongside Shiner, the RepAir team includes co-founder and Chairman Yehuda Borenstein, CTO Ben Achrai, PhD, and Board Member Yushan Yan, PhD.

Andrew Shebbeare, managing partner at Counteract, said: “We firmly believe in the part Direct Air Capture will play but are also convinced that today’s technology needs to evolve. With a promising platform and exceptional team, we are convinced RepAir is advancing the state of the art and will help pave the way for responsible and scalable DAC.”

Eli Cymbalista, CEO of ESIL, said: “Our aim is to accelerate and commercialize startups delivering economically viable solutions that support the transition to a NetZero world. We believe RepAir fits that brief exactly and are excited to contribute the skills and resources of our partners’ network to help accelerate their progress.”

In an interview with me, Shiner added: “We will eventually have more blocks that can scale like Lego. We can scale in a modular nature. So we can place our device next to, say, a wind farm, where we get the energy to populate the device. We’re very flexible in terms of where we locate the device because we use air rather than the emitted pollution from a chimney.”

CALGARY — Heavily discounted natural gas prices in Alberta have domestic producers frustrated they could miss out on much of the upside of a global rally as natural gas prices skyrocket ahead of the winter.

Natural gas prices are hitting multi-year seasonal highs across North America due to a combination of low storage levels and red-hot demand from overseas markets even before winter heating season begins in earnest. The Henry Hub benchmark price in Louisiana traded for US$5.69 per thousand cubic feet on Tuesday, while gas prices at Dawn, Ont. traded at US$5.19 per mcf according to ATB Capital Markets.

By contrast, Alberta’s AECO benchmark price averaged at US$3.12 per mcf on Tuesday — which is at a just 55 per cent of the U.S. Henry Hub benchmark price, or a US$2.57 per mcf discount.

Producers point to maintenance and expansion work on TC Energy Corp.’s Nova Gas Transmission Ltd. (NGTL) pipeline system for the disconnect between Alberta’s market and the rest of North America. NGTL is the largest gas transmission system in Canada and TC Energy also operates the largest network of export pipelines, moving Alberta gas eastward to Ontario and westward to San Francisco.

“The AECO basis, which is really that delta between the two markets AECO and Henry Hub and adjusted for different markets and currencies, is quite large right now,” said Darren Gee, president and CEO of Peyto Exploration and Development Corp., adding that he’s concerned the discount will persist through the winter as TC Energy is expanding its gas transmission system in the province.

“It actually is quite steeply disconnected right now,” he said, referring to the pricing relationship between AECO and U.S. benchmarks Henry Hub and NYMEX.

Gee said that in years past, a $2 per mcf AECO discount was common as there were restrictions on the NGTL system. Now that natural gas prices are higher, AECO continues to trade above the bargain-basement levels of the last several years, but remains heavily discounted to other North American benchmarks during periods of NGTL maintenance.

In an effort to diversify away from the volatility and discounts of the AECO benchmark, producers pay to move their gas on long-haul pipelines to the U.S. West Coast, Chicago and Central Canada, where prices typically trend higher than in Alberta.

“While we do not comment or speculate on the dynamics of the market, we are able to confirm that all outages in question are planned in nature, closely coordinated with our customers and communicated to industry months in advance,” TC Energy said an emailed statement.

Calgary-based TC Energy said the maintenance and expansion work is part of the company’s $8 billion in spending to expand the system and remove bottlenecks over a five-year period. The pipeline giant said flows on the system “have remained robust” at 12.2 billion cubic feet per day.

“While conducting maintenance is an integral part of ensuring the safe and reliable operations of the system, we have and will continue to work with our customers to ensure we can complete this important work while mitigating impacts whenever possible,” the company said.

TC Energy did not say when the scheduled maintenance will wrap up as natural gas producers watch prices jump sharply in other hubs even before the winter heating season begins to draw large quantities of gas out of storage.

“It’s supposed to all be coming on in pieces, mid-October by November 1st,” said Raymond James analyst Jeremy McCrea, adding the scheduled maintenance normallyends before winter heating season beginsand prices tick upward seasonally.

“The problem though, and I’m hearing this from a number of producers, given how rampant COVID-19 is here in the province, there is just one delay after another,” McCrea said, adding that outbreaks among field workers is slowing work on a number of projects.

In response to a question about COVID-19 delays at its operations, TC Energy said in an emailed response, “Flows and utilization levels across our network continue to be in line with historical norms despite the ongoing impacts of COVID-19, extreme weather events and energy market volatility.”
