The unique brainpower of octopuses—known for their intelligence and Houdini-like escapes—has been revealed by University of Queensland researchers.

Dr. Wen-Sung Chung from UQ's Queensland Brain Institute is part of a team that studied four octopus species using MRI techniques to produce detailed 3D images for comparing their unique brain structures.

He said octopus brains varied, depending on where a species lived, when it was active and if it interacted with other animals.

"The octopus is a master of camouflage, capable of solving complex tasks and their cognitive ability is said to approach that of some small mammals," Dr. Chung said.

"We investigated four species, including one deep-sea octopus, one solitary nocturnal species and two different reef dwellers active during daylight."

Dr. Chung said the octopus found in deep waters had a smooth brain like marsupials and rodents, suited for its slow pace of life and limited interactions with other animals.

The reef octopuses had a significantly larger brain with some properties similar to primates, adapted for complex visual tasks and social interaction in a busy, well-lit environment.

"These octopuses have some remarkably complex behaviors not known in other octopuses," Dr. Chung said.

"For example, collaborative hunting with reef fish has been recorded, where the octopus usually leads and coral trout join by either actively seeking prey or opportunistically snatching small organisms flushed out by the octopus.

"The ability to receive and respond to gestures between different species as part of collaborative hunting demonstrates that octopus species have complex cognitive abilities."

The differences in brain structures between species relates to the size of the brain's surface area, with a larger surface area indicating a more complex nervous system and increased cognitive ability.

Professor Justin Marshall heads the team that was first to discover the differences in brain structure, opening the door to a better understanding of the complexity and evolution of these apparently "smart" animals.

He said the team's ongoing research aimed to provide insights into how octopus brain structure is linked to behavior, vision and advanced cognition.

Riding on the success of the documentary, My Octopus Teacher, a team of Queensland researchers has studied the brains of octopuses using MRI technology to find out why they are so smart.

Key points:
Queensland researchers studied the brains of four octopus species
Reef octopuses had significantly larger brains
Some teamed up with reef fish to hunt for food

The team from the University of Queensland's Brain Institute took four species of octopus, two of which live on the Great Barrier Reef, and studied their brain structure using ultra-detailed MRI imaging.

Results, published in scientific journal Current Biology, have shown for the first time that reef octopuses had a significantly larger brain than octopuses that lived in deep-sea waters – a discovery which will provide insights into how brain structure is linked with behaviour and cognition.

Post-doctoral researcher Wen-Sung Chung said one of the purposes of the study was to find out why the invertebrates had such a short life span – approximately one year.

"Why do they put so much power, so much energy in developing their brains?


"Keeping a brain with so many neurons is really costly," Dr Chung said.

Dr Chung said octopuses are estimated to have 500 million neurons.

"They are quite amazing; they have eight arms and no joints and they need to control their movement across the very complex seascape.

"They are also totally colour blind, they can only see blue or green, and how they manage to see reef and then make themselves well matched with the background is a big unknown," Dr Chung said.

Unusual inter-species friendships

Dr Chung said researchers also investigated the relationship which developed between octopuses and reef fish while hunting.

He said the observations were made during visits to Lizard Island, off the coast of Far North Queensland.

"The fish usually follow the octopus, the octopus will search for crabs, and then somehow the small food item will come out and the fish will eat it.

He said the animals were able to communicate with each other to hunt together.

"The ability to receive and respond to gestures between different species as part of collaborative hunting demonstrates that octopus species have complex cognitive abilities," Dr Chung said.

He said the finding was significant, considering the species' usual behaviour.

"Most of the time they live solitary, and very rarely interact with others.

"For those nocturnal especially, they live by themselves until the mating season and find a mate, otherwise they will just go out alone to catch crab or clams."

Kaleidoscope of Deep-Sea Life Found Near Hydrothermal Vents Off Mexican Coast

Some of these unique features reached temperatures up to 549 degrees Fahrenheit

Aside from discovering the fascinating geology of the Gulf’s floor, the team also found diverse sea life thriving on or near the vents and their mineral structures. Researchers photographed tubeworms living on or near the vents seen here. ROV SuBastian/Schmidt Ocean Institute

In the Gulf of California off the coast of La Paz, Mexico, a deep-sea expedition discovered a thriving hydrothermal vent ecosystem, complete with six new possible species of arrow worms, mollusks, crustaceans, and roundworms, reports Molly Taft for Gizmodo.

A remotely operated vehicle (ROV) captured stunning images of the ecosystem’s calcite spires, hydrothermal mirror pools, and iridescent scale worms. With the ROV, researchers studied various hydrothermal vents, some reaching temperatures up to 549 degrees Fahrenheit, per a statement.

The 33-day long expedition aboard the research vessel Falkor included researchers from both Mexico and the United States. During this time, the researchers focused on mapping the seafloor, exploring tectonic processes, measuring heat flow, sampling microbes, and geophysics of the hydrothermal vents in the Gulf, a statement reports.

The Gulf of California is a body of water filled with diverse sea life that falls about half a mile deep with a few depressions reaching greater depths. The gulf formed 12.5 million years ago when the Baja Peninsula started to pull away from the rest of North America along the San Andreas Fault system. Compared to other geological features in the area, it's actually considered quite young.

Hydrothermal vents form when two tectonic plates move away from each other and form a fissure at the bottom of the ocean. Water will then seep through these cracks into Earth’s red-hot mantle below. When the water touches the mantle, it will shoot back towards the surface, creating a vent of rushing, steaming hot water, Live Science reports.

Underwater sea vents were only recently discovered in the 1970s, and scientists are still learning about life that thrives from them, per Gizmodo.

“The deep ocean is still one of the least explored frontiers in the solar system,” one of the expedition’s lead researchers Robert Zierenberg, a geologist at the University of California, Davis, said in a statement from a 2018 expedition. “Maps of our planet are not as detailed as those of Mercury, Venus, Mars, or the moon, because it is hard to map underwater. This is the frontier.”

Previous expeditions from 2012, 2015, and 2018 laid the groundwork and mapped the seafloor for exploration in 2021. First, researchers used a yellow torpedo-shaped robot called an autonomous underwater vehicle (AUV) to map out the seafloor and the features of the sea vents. To get a closer look at the hidden sea world, researchers used yellow a mini van–sized ROV named SuBastian, which allowed them to determine that the ducts are active.

Hydrothermal vents can actually expel various colors of liquid. For example, vents called black smokers expel sooty-colored plumes because the liquid encounters basaltic rocks and iron metals as the water rushes towards the surface. But researchers on this recent expedition discovered a vent that expels a clear, sparkling liquid in the Pescadero Basin at the south end of the Gulf of California. Scientists suspect sediment from Mexico’s mainland ends up in the vent, which in turn filters out basalts and other metals, leaving behind only shimmering minerals, reports Nicoletta Lanese for Live Science.

The floating mineral forms ledge-like deposits called flanges. The vent’s liquid pools underneath these structures at times, creating a type of reverse waterfall or upside-down lake effect. When water accumulates in these small ledges, they will at times collapse, creating small mounds. The minerals can also form tall structures dubbed chimneys, per Live Science.

Aside from discovering the fascinating geology of the Gulf’s floor, the team also found diverse sea life thriving on or near the vents and their mineral structures. Some animals even seemed to gravitate toward certain vents. Sites towards the south had more shining blue worms, for example. Researchers also spotted Oasisia tubeworms living on or near other vents, Gizmodo reports.

Until another expedition is organized, the team plans to examine the bacterial mats and other sea life samples to understand their genetics and morphology—and determine whether these creatures can be categorized as a new species.

“This expedition has simultaneously built on our past exploration of the Alarcon and Pescadero basins and enabled further exploration in the adjacent, but poorly known Farallon and Carmen Basins,” David Caress, an engineer at the Monterey Bay Aquarium Research Institute, said in a statement.

Biological ‘treasure troves’ need mapping in marine protection plan

A treasure trove of biological hot spots sheltering ancient rockfish, delicate corals and sponges hidden inside the inlets of British Columbia’s isolated central coast merit protection, a new study indicates.

A number of sites of exceptional biodiversity — well-known to the region's First Nations but previously undocumented by science — have been identified with joint research between the Central Coast Indigenous Resource Alliance (CCIRA) and Fisheries and Oceans Canada (DFO), said one of the study’s lead authors, Alejandro Frid.

The hot spots studied fall within the territories of the Kitasoo/Xai’xais, Wuikinuxv, Nuxalk and Heiltsuk Nations, which are also involved in the CCIRA, Frid said.

“None of (the hot spots) was a surprise to the First Nations,” Frid said, adding a number of sites identified through traditional knowledge need more exploration. “But from a formal scientific standpoint, there were no surveys of what was there in terms of rockfishes, corals and sponges.”

All the biodiverse pockets on the central coast are important to preserving the marine ecosystem, but it was particularly interesting to find significant populations of rockfish, or the fish family Sebastinae, some of which can live as long as 200 years, Frid said.

“I was personally surprised to see a large amount of some of the really long-lived rockfishes being way up in the fjords,” he said “Fishery scientists think of them as being more associated with areas further out closer to the continental shelf.”

The hot spot study — which involves 11 years of survey data gathered in a variety of ways, including scuba dives and DFO’s remote video camera to explore as deep as 500 metres — will contribute essential information to a new network of marine protected areas (MPAs) being developed that will stretch across extensive sections of B.C.’s coast, said Frid, CCIRA’s science co-ordinator.

The Northern Shelf Bioregion MPA network will protect important areas of biodiversity along the coast from Quadra Island in the south to the border with Alaska in the north — approximately two-thirds of the West Coast.

Rockfish populations, decimated by commercial fishing, are particularly vulnerable and would benefit from added protections, Frid said.

Yelloweye rockfish in particular are culturally significant and important to the food security of area First Nations, Frid said, but the fish has suffered a 67 percent drop in biomass population over a century leading up to 2018.

Beyond being ecologically valuable and important ecosystems for feeding and breeding other marine species, sponge and coral beds capture and store significant amounts of carbon, so are also important from a climate change perspective, Frid said.

However, these seabeds are particularly vulnerable to bottom-contact fishing gear, such as prawn traps, long lines or bottom trawling, which involves dragging a net along the ocean floor, he said.

“So, the benefits of protecting corals and sponges in marine protected areas had immediate benefits by just stopping the collective damage to these species groups that play an important role as natural carbon stores.”

Mike Reid, manager of the Heiltsuk Nation’s stewardship department, agreed surveying the hot spots identified by First Nations in numerous areas on the central coast was a key step to protecting them.

“The nations know where the spawning grounds are for rockfish and other species, and we were aware of the corals and sponges,” Reid said.

“But through this process, we're able to get the exact co-ordinates to those spots and incorporate those into the MPA process.”

The central coast nations started the planning process for marine protected areas in their territories in 2007, first with the province and now also in conjunction with the federal government, he said.

Stakeholders have provided feedback around draft plans to protect areas in the entire Northern Shelf Bioregion, which is expected to go out for public input at the beginning of 2022.

The larger MPA network is subject to a tripartite process between the federal and provincial governments and 13 First Nations, with input from a variety of stakeholder agencies and groups.

While food security and cultural reasons are important for preserving rockfish, protection is the paramount concern for the fish, corals and sponges, Reid said.

“Our goal has always been conservation. And we've seen that slip with the current (DFO) management regime,” he said.

“There's no balance there anymore. For the most part, (marine resources) are managed for harvesting, not for ecosystem health.”

Climate change has also had cumulative impacts on other marine resources important to First Nations such as salmon, sea urchins and seaweed, he added.

Adding hot spots in the region to future MPAs will provide ecological benefits for generations, Reid said.

“A lot of people see the MPA process as a takeaway, but we see it the other way round,” he said.

“It’s more or less putting these areas in a bank for children, and our children's children.

“Protected areas that are left alone long enough will thrive and repopulate, and eventually the biomass inside will overflow into the outside for longer-term benefits.”

The hot spots identified in the study represent the top 20 per cent of an index of ecological importance that took into account species distinctiveness, vulnerability and abundance, or lack thereof, as well as key roles in the food web, Frid said.

Key hotspots for rockfish, corals and sponges should also be considered for interim protection while the Northern Shelf Bioregion network is being finalized, a process that can take years, Frid said.

But regardless of when and where protections of biodiverse hot spots go into place, such protections will be meaningless without enforcement, he said.

“None of this (protection) will really matter if there’s not enough resources for monitoring and enforcing compliance from fishers,” Frid said.

“Fisheries and Oceans Canada will definitely need to step up… if any of these closures are actually going to meet their conservation goals.”

Mapping The Rise Of Solar Energy

By ZeroHedge - Nov 21, 2021, 12:00 PM CST

• Solar power led the renewable energy push in 2021, with 127 gigawatts installed in 2020
• China is the undisputed leader in solar installations, with over 35% of global capacity 
• Although Australia hosts a fraction of China’s solar capacity, it tops the per capita rankings

The world is adopting renewable energy at an unprecedented pace, and solar power is the energy source leading the way.

Despite a 4.5% fall in global energy demand in 2020, Visual Capitalist's Govind Bhutada notes that renewable energy technologies showed promising progress. While the growth in renewables was strong across the board, solar power led from the front with 127 gigawatts installed in 2020, its largest-ever annual capacity expansion.

The above infographic uses data from the International Renewable Energy Agency (IRENA) to map solar power capacity by country in 2021. This includes both solar photovoltaic (PV) and concentrated solar power capacity.

The Solar Power Leaderboard

From the Americas to Oceania, countries in virtually every continent (except Antarctica) added more solar to their mix last year. Here’s a snapshot of solar power capacity by country at the beginning of 2021:

*1 megawatt = 1,000,000 watts.

China is the undisputed leader in solar installations, with over 35% of global capacity. What’s more, the country is showing no signs of slowing down. It has the world’s largest wind and solar project in the pipeline, which could add another 400,000MW to its clean energy capacity.

Following China from afar is the U.S., which recently surpassed 100,000MW of solar power capacity after installing another 50,000MW in the first three months of 2021. Annual solar growth in the U.S. has averaged an impressive 42% over the last decade. Policies like the solar investment tax credit, which offers a 26% tax credit on residential and commercial solar systems, have helped propel the industry forward.

Although Australia hosts a fraction of China’s solar capacity, it tops the per capita rankings due to its relatively low population of 26 million people. The Australian continent receives the highest amount of solar radiation of any continent, and over 30% of Australian households now have rooftop solar PV systems.

China: The Solar Champion

In 2020, President Xi Jinping stated that China aims to be carbon neutral by 2060, and the country is taking steps to get there.

China is a leader in the solar industry, and it seems to have cracked the code for the entire solar supply chain. In 2019, Chinese firms produced 66% of the world’s polysilicon, the initial building block of silicon-based photovoltaic (PV) panels. Furthermore, more than three-quarters of solar cells came from China, along with 72% of the world’s PV panels.

With that said, it’s no surprise that 5 of the world’s 10 largest solar parks are in China, and it will likely continue to build more as it transitions to carbon neutrality.

What’s Driving the Rush for Solar Power?

The energy transition is a major factor in the rise of renewables, but solar’s growth is partly due to how cheap it has become over time. Solar energy costs have fallen exponentially over the last decade, and it’s now the cheapest source of new energy generation.

Since 2010, the cost of solar power has seen a 85% decrease, down from $0.28 to $0.04 per kWh. According to MIT researchers, economies of scale have been the single-largest factor in continuing the cost decline for the last decade. In other words, as the world installed and made more solar panels, production became cheaper and more efficient.

This year, solar costs are rising due to supply chain issues, but the rise is likely to be temporary as bottlenecks resolve.

Before geoengineering to mitigate climate change, researchers must consider some fundamental chemistry

 as geoengineering using sulfur compounds to create a sunshield in the upper atmosphere

It's a tempting thought: With climate change so difficult to manage and nations unwilling to take decisive action, what if we could mitigate its effects by setting up a kind of chemical umbrella—a layer of sulfuric acid in the upper atmosphere that could reflect the sun's radiation and cool the Earth?

According to a new study in the Journal of the American Chemical Society, a collaboration among Penn scientists and two groups in Spain, atmospheric conditions in the stratosphere pose a challenge to generating sulfuric acid, making its production less efficient than might have previously been expected. Thus more groundwork exploring the chemistry of how sulfuric acid and its building blocks will react in the upper atmosphere is required in order to confidently move forward with this climate geoengineering strategy, the researchers say.

"These fundamental insights highlight the importance of understanding the photochemistry involved in geoengineering," says Joseph S. Francisco, an atmospheric chemist in Penn's School of Arts & Sciences and a co-corresponding author on the study. "That's critically important and it's something that's been ignored."

Using sulfuric acid to blunt the sun's rays as a means of curbing climate change impacts is based on a natural phenomenon: When volcanoes erupt, the sulfur they emit creates localized—or sometimes even far-reaching—cooling clouds that filter the sun. But those clouds emerge in the troposphere, which ranges from the Earth's surface to about 10 kilometers up. Geoengineering using sulfuric acid would happen a good deal higher, in the stratosphere, from about 10 to 20 kilometers above the planet.

Conditions change as the altitude increases. Notably, the air becomes drier, and the energy of the sun's rays becomes stronger. In the new work, Francisco, his postdoc Tarek Trabelsi, and colleagues from Spain's Rocasolano Institute of Physical Chemistry and the University of València partnered to explore how these variables affected the chemical reactions involved in making sulfuric acid.

The major inputs are sulfur dioxide (SO2), which reacts with hydroxyl radicals (OH), a kind of atmospheric "detergent," to create HOSO2. HOSO2 reacts with oxygen to create sulfur trioxide (SO3), which then reacts with water vapor to create sulfuric acid. Aerosols formed from the sulfuric acid have the ability to reflect sunlight.

These reactions are well characterized; together, they are responsible for creating acid rain in the troposphere. But whether that chemistry would work in the stratosphere and achieve the same efficiency was unknown.

To find out, the team used quantum chemistry—an approach that considers the ground, transition, and excited states of atoms and molecules—to consider how HOSO2 and SO3 would behave in the stratosphere's conditions of high light and low humidity. Though geoengineering approaches factor in the ability of these two molecules to reflect sunlight, the researchers found that when HOSO2 is produced in the stratosphere, solar radiation causes the molecule to quickly photolyze, essentially breaking apart into its component parts, including sulfur dioxide, which is harmful to humans in high concentrations.

Research by the Penn-led group indicated that HOSO2 would photolyze, or break apart, in the stratosphere, likely reducing the efficiency of producing sulfuric acid at those altitudes. Credit: Francisco laboratory

"One of the implications of this finding is, if you put sulfur dioxide up there, it's going to just be recycling around," Francisco says. "So it opens the door to whether we have a full understanding of atmospheric sulfur chemistry up in the stratosphere."

Declining HOSO2 would also blunt the efficiency of producing sulfuric acid, the researchers note, possibly lessening the effectiveness of a chemical sunshade.

In contrast, the researchers found that SO3 levels remained quite stable in stratospheric conditions. "We know it reacts with water, but we don't know a lot else about how it might react," says Francisco. "Will the atmosphere find a way to get rid of the SO3 or will it collect somewhere and start initiating new chemistry elsewhere?"

Indeed, the researchers note that it's crucial to understand what other reactions these molecules could be entering into in the stratosphere. "This work points to a cautionary note: If the SO3 chemistry is different, then how does it interact with the other chemistry that's currently going on in the stratosphere," he says. "We need to consider whether there are any kind of chemical concerns that we need to think about up front."

The findings also highlight the need for a Plan B if the atmospheric chemistry doesn't play out as expected. "It raises a fundamentally important question," Francisco says. "If we put the sulfur dioxide in, can we get it out of the stratosphere?"

Francisco's group is working on continuing to apply cutting-edge quantum methodologies to examine how photochemistry interacts with atmospheric models to generate a more complete understanding of various geoengineering scenarios.

"This is the first time that you're taking results from fundamental physics and chemistry and mapping them into climate models to look at the three-dimensional atmospheric impact," Francisco says.

And while some scientists are already proposing to trial a geoengineering approach using SO2, Francisco and his colleagues underscore that the outcomes depend on some aspects of sulfur chemistry that remain unknown.

"This brings to the forefront the need to make the community aware that there's more fundamental chemistry that we need before we start to understand the full chemical impact of this approach," Francisco says.Mechanism deciphered: How organic acids are formed in the atmosphere\

Singapore-based firm to build $13.7b wind farm off Ireland for green hydrogen facility

Green hydrogen - produced by renewable electricity - is seen as a clean alternative to natural gas.

LONDON (BLOOMBERG) - A Singapore-based offshore wind developer has signed an agreement to build a huge US$10 billion (S$13.7 billion) wind farm off the coast of Ireland to power a green hydrogen facility.

Green hydrogen - produced by renewable electricity - is seen as a clean alternative to natural gas for industries such as steel and chemicals, with energy majors from Equinor to BP piling in to the technology. Europe has a goal of six gigawatts (GW) of installed green hydrogen by 2024, and 40GW by 2030.

Enterprize Energy's 4GW wind farm will supply electricity for hydrogen production and consumption in Ireland, or for conversion into ammonia that can exported, chief executive officer Ian Hatton said in an interview.

"We see Europe as being a net consumer of green hydrogen," Mr Hatton said. "Our overall model is about developing production of green hydrogen in locations where the natural resources are going to give you the lowest cost and then bring it into the market. So Ireland, to us, is a key hub in that strategy."

Enterprize is not seeking a subsidy for the wind farm. It will raise money through project financing arranged by investment banking firm Societe Generale as well as from private equity investment, Mr Hatton said.

The project will provide electricity for a 4GW hydrogen facility in Ireland being developed by E1-H2 and Zenith Energy called Green Marlin, which could be generating as soon as 2026. The energy companies have signed a precursor to a power purchase agreement, with EI-H2 off-taking the energy.

The farm will use articulated wind columns, deep-water technology used by the oil and gas industry for exploration, and production platforms. Enterprize has signed deals with oil and gas development company Sapura Energy and foundation supplier Offshore Design Engineering, which will supply the articulated wind columns for the project.

The company is also developing a 3.4GW offshore wind farm in Vietnam and is looking at Brazil.

"For the past year, we've been targeting locations where we can effectively play join-the-dots with projects that will bring low-cost hydrogen to Europe and maybe to Japan," Mr Hatton said.

Also taking advantage of the region's windy conditions, the British government awarded £9.4 million (S$17.2 million) on Monday (Nov 22) to develop an electrolyser for green hydrogen from the onshore Whitelee Windfarm in Scotland. The funding is for a 10MW electrolyser and associated four tonnes of storage at the 20MW hydrogen production and storage facility, ITM Power said in a statement.

Whitelee green hydrogen facility to power public transport

IMAGE SOURCE,PA MEDIA
The green hydrogen facility will be based at Whitelee Windfarm in East Renfrewshire

A wind farm is to become home to a state-of-the-art hydrogen storage facility which could eventually produce enough clean energy to help power the next generation of public transport.

The UK government has awarded the project, based at Whitelee Windfarm in East Renfrewshire, £9.4m.

It said the project would help Glasgow reach net zero by 2030.

The cash will go towards developing the country's largest electrolyser, which converts water into hydrogen.

The hydrogen produced can be easily stored and transported to where it is needed.

Splitting water and capturing the released hydrogen requires energy, and the project will use electricity produced from the wind farm, the largest onshore farm in the UK, to create the gas.

Watch: What is hydrogen energy and why is it important?

One use for the hydrogen generated will be to support local transport. The facility is expected to make so much of the zero-carbon fuel that it could provide the equivalent of enough zero-carbon fuel for 225 buses travelling to and from Glasgow to Edinburgh each day.

Greg Hands, the UK government's energy and climate change minister, said: "This first-of-a-kind hydrogen facility will put Scotland at the forefront of plans to make the UK a world-leading hydrogen economy, bringing green jobs to Glasgow, while also helping to decarbonise local transport - all immediately following the historic COP26 talks."

And Alister Jack, secretary of state for Scotland, said the project showed "how serious the UK government is about supporting projects that will see us achieve net zero by 2050".

He added that it had never been more important to "champion" projects like this, which embrace new hydrogen technology while creating highly-skilled jobs.

The partnership, made up of ScottishPower, ITM Power and BOC, is currently going through the planning process for the new facility and aims to have green hydrogen available to the commercial market by 2023.

Hydrogen vs electricity

Some argue that for public transport vehicles like buses, hydrogen is too expensive and electricity would be a better, cheaper alternative.

However Dr Graham Cooley, chief executive of ITM Power, told the BBC's Good Morning Scotland programme that hydrogen was particularly good for heavy vehicles "where you value payload".

He said: "You can make a vehicle that's very long duration - in other words, it can travel a long range without compromising the weight.

"If you want to travel a long distance using a battery, you need more and more batteries which makes the vehicles very heavy. You see vehicle manufacture now all over the world rolling out commercial vehicles based on hydrogen which have very long ranges and very short recharging or refuelling time."

Meanwhile, Friends of the Earth Scotland director Richard Dixon argued that green hydrogen should be reserved for "special uses" in industry, rather than mainstream uses like public transport.

He told the programme: "It's three times more sensible to use it [renewable electricity] as electricity rather than to use it to turn it into hydrogen - you've lost two thirds of the energy in making the hydrogen and then using it.

"We have such a desperate need to convert our homes to electric heating and to convert transport to electricity to get out of fossil fuels. That should be absolute top priority."

Unique climate-saving hydrogen scheme in Scotland given £10m from UK Treasury



By Hannah Rodger @HRwritesnewsWestminster Correspondent, The Herald

A UNIQUE climate-saving project has been awarded funding from the UK Government.

A first of its kind, the new hydrogen storage project near Glasgow has been backed by almost £10m of funding from the Treasury and will help to decarbonise the country's transport sector.

It is also hoped to create highly-skilled jobs and help Glasgow to become net zero by 2030.

The award of £9.4m will see the Whitelee Green Hydrogen project develop the country's largest electrolyser - a system which converts water into hydrogen gas, which is then stored as energy.

This energy will then be used to supply local transport providers with zero-carbon fuel.

It will be located at the Whitelee windfarm, run by Scottish Power, and will be able to produce enough of the 'green' hydrogen to power the equivalent of 225 buses going from Glasgow to Edinburgh every day once it is stored.

Energy and Climate Change Minister Greg Hands MP said: “This first-of-a-kind hydrogen facility will put Scotland at the forefront of plans to make the UK a world-leading hydrogen economy, bringing green jobs to Glasgow, while also helping to decarbonise local transport – all immediately following the historic COP26 talks.

“Projects like these will be vital as we shift to a green electricity grid, helping us get the full benefit from our world-class renewables, supporting the UK as we work to eliminate the UK’s contribution to climate change.”

Secretary of State for Scotland Alister Jack said:“This tremendous investment at Whitelee Wind Farm illustrates how serious the UK Government is about supporting projects that will see us achieve net zero by 2050."

RED Pope to young people: We need you to protect environment

By The Associated Press

Posted Nov 21, 2021, 

Pope Francis on Sunday praised young people for their efforts to protect the Earth’s environment and told them to “be the critical conscience of society.”

Francis celebrated Mass in St. Peter’s Basilica, filled with hundreds of young faithful, to mark a church day focused on youth in dioceses worldwide.

“You have been entrusted with an exciting but also challenging task,” the pontiff said, ”to stand tall while everything around us seems to be collapsing.”

Francis expressed thanks “for all those times when you cultivate the dream of fraternity, work to heal the wounds of God’s creation, fight to ensure respect for the dignity of the vulnerable and spread the spirit of solidarity and sharing.”

He noted that many young people have criticized environmental contamination.

“We need this,” Francis said.

The pontiff said that in a world that “thinks only of present gain, that tends to stifle grand ideals, you have not lost the ability to dream.”

“Be free and authentic, be the critical conscience of society,” Francis exhorted young people.

Social justice and care of the environment have been key messages of his papacy.

The pope is expected to meet with young people from all over the world at the Catholic church’s jamboree in Lisbon, Portugal, in August 2023.
