S'pore has opportunities to expand into green hydrogen and carbon services as it overcomes energy crisis: Experts


Shabana Begum

SINGAPORE - In crisis lies opportunity, and this can be seen in the opportunities that could open up as Singapore attempts to wean itself off fossil fuels amid an energy crisis.

The opportunities lie not only in the renewable energy sector, but also in areas such as green finance, carbon services and green hydrogen, said panellists at a roundtable organised by The Straits Times which aired on Earth Day on Friday (April 22).

One of the panellists, Dr Victor Nian, an adviser at the Centre for Strategic Energy and Resources, said there is potential for Singapore to position itself as a hydrogen hub in the future, and supply the cleaner fuel to the region.

For instance, the oil refineries and petrochemical plants in Singapore could in the future be repurposed to produce and store green hydrogen, which refers to hydrogen fuel produced by renewables.

"Think back to the 1960s, where our philosophy of having refineries on Bukom Island or Jurong Island in serving the neighbourhood, could be replicated in the hydrogen story, where we, as a country can become a hub for hydrogen production from clean energy sources, and (also) sell them to the region," he said.

Green hydrogen, which is produced by splitting water into hydrogen and oxygen by using renewable electricity, emits no carbon dioxide during the production process, making it a cleaner fuel.

The other panellists were ST climate change editor David Fogarty; Ms Swati Mandloi, a youth delegate from Singapore for the recent climate change conference in Glasgow (Cop26); and ST environment correspondent Audrey Tan.

The roundtable was moderated by Mr Warren Fernandez, ST editor and editor-in-chief of SPH Media Trust's English, Malay and Tamil Media Group.

The roundtable - aired on ST's YouTube channel and website on Friday - revolved around the theme of whether surging energy costs would spark a global rethink about the dependence on fossil fuels, and the current challenges of speeding up the adoption of renewables.

Last year, oil and fossil fuel prices soared, causing electricity bills to spike and petrol prices to rise. The war in Ukraine then worsened the world's energy crisis.

Mr Fogarty said carbon services and trading in Singapore are a growing area since one of the key issues that polluting companies are facing is in reducing their emissions in some parts of their supply chains.

Hence, they turn towards carbon offsets, where the companies buy a carbon credit from a renewable energy plant or a forestry restoration project to "offset" their emissions.

"The investment around those projects, and the financing (and auditing) of them is a growing area. Executing those projects on the ground also takes time and money."

Mr Fogarty added that issuing green bonds - financial instruments used to fund projects with environmental benefits - is an emerging area, and that the nation can also explore novel technologies in extracting carbon dioxide.

"Singapore is a great hub for a lot of these things. It's got the finance, it's got the technology, and it can bring in the brains to do it."

Reduce emissions from energy sources, but don't neglect biodiversity and human rights: Panellist

On Singapore as a hydrogen hub, Ms Tan noted that it is currently challenging to produce green hydrogen here due to the small proportion of the nation's energy mix coming from renewables.

By 2030, the aim is to have solar energy - the nation's most viable form of clean energy now - cover 4 per cent of Singapore's total electricity demand.

The 4 per cent will comprise at least 2 gigawatt-peak of solar energy or the equivalent of powering about 350,000 households a year.

Currently, more than 95 per cent of the country's energy mix comes from natural gas, the cleanest form of fossil fuel.

Ms Tan said: "By 2030, 4 per cent (coming from) solar is quite small. For us to harness hydrogen in a larger way, hydrogen has to be imported, and we have to find ways to store hydrogen safely."

It was reported last year that Singapore is engaging local and international stakeholders to bring down the cost of hydrogen technology and develop global regulatory standards, to establish global hydrogen supply chains.

Hope for green future also rests on harnessing hydrogen, trapping carbon dioxide

Dr Nian added that if nuclear energy - which Singapore is looking into - takes off here, it could be used to produce clean hydrogen fuel here.

Audience member Jan Holm, 53, executive vice-president of Seaborg Technologies, a cleantech company, asked the panellists where they see the biggest opportunities for Singapore moving forward, as the nation rides the energy crisis wave.

Dr Nian said Singapore's rich talent pool can help pave the way for advances in the clean energy and technology sector - from "Generation IV" nuclear technologies to even new industries within the cleantech scene.

Generation IV nuclear power involves a system of fuel fabrication plants and facilities that would overcome some of the shortcomings and safety issues with current nuclear power plants.

"Advanced technologies (in the nuclear sector) are still in development. As a newcomer country, we can ramp up our research and development capabilities so that we catch up with this wave, and become one of the leading innovators in these areas," added Dr Nian.

"I think that is where the golden opportunity lies with a country that is educated... and is open to new options. We might even be seeing new industries being established. It could be data centres, it could be hydrogen, it could be nuclear."

How safe is nuclear power for Singapore?

Last month, the Energy Market Authority released its Energy 2050 Committee Report which identified emerging low-carbon sources such as hydrogen, geothermal and nuclear energy as means to bring down the country's emissions to net zero by or around 2050.

Ms Tan noted that while the report was commissioned before the surge in energy prices started, and the Ukraine-Russia conflict, EMA still chose to release the report amid the energy crisis.

"(EMA) could have chosen to release the report at a later date after prices have stabilised, but the fact that they still chose to release it when we are all suffering from energy price spikes, that seemed like a commitment... that Singapore is committed to tackling this crisis."

Singapore's power sector now produces about 40 per cent of the country's emissions, but the sector can realistically reach net zero by 2050, the report said.

Ms Swati hopes that the current energy and existing climate crises will allow humankind to explore opportunities for a better future world.

She added that through nature-based solutions, for example, individuals' relationships with the natural environment will improve and benefit people, enriching their lives.
