AI finds a cheaper way to make green hydrogen
Researchers at the University of Toronto are using artificial intelligence to accelerate scientific breakthroughs in the search for sustainable energy. They used the Canadian Light Source (CLS) at the University of Saskatchewan (USask) to confirm that an AI-generated “recipe” for a new catalyst offered a more efficient way to make hydrogen fuel.
To create green hydrogen, you pass electricity that’s been generated from renewable resources between two pieces of metal in water. This causes oxygen and hydrogen gases to be released. The problem with this process is that it currently requires a lot of electricity and the metals used are rare and expensive.
The AI program the team developed took over 36,000 different metal oxide combinations and ran virtual simulations to assess which combination of ingredients might work the best. Abed then tested the program’s top candidate in the lab to see if its predictions were accurate. The alloy, a combination of the metals ruthenium, chromium, and titanium in specific proportions, was a clear winner, according to Abed. “The computer’s recommended alloy performed 20 times better than our benchmark metal in terms of stability and durability,” said Abed. “It lasted a long time and worked efficiently.”
Hysata raises $111m USD led by bp Ventures and Templewater
Australia-based company Hysata is developing new high-efficiency electrolysers that aim to produce green hydrogen at scale with higher energy efficiency and lower costs than alternative technologies. The company’s technology combines engineering and science in a unique capillary-fed alkaline electrolyser that uses less energy to convert water to hydrogen.
bp Ventures and Templewater led the recent $111.3 million USD investment round in the company, with strong backing from existing major strategic and financial investors IP Group Australia, Kiko Ventures (IP Group plc’s cleantech platform), Virescent Ventures on behalf of Clean Energy Finance Corporation, Hostplus, Vestas Ventures and BlueScopeX. The company also welcomed new major strategic and financial investors POSCO Holdings, POSCO E&C, IMM Investment Hong Kong, Shinhan Financial Group, Twin Towers Ventures, Oman Investment Authority’s VC arm IDO and TelstraSuper.
Hysata will use the funding to expand production capacity at its iconic beachside manufacturing facility in Wollongong, New South Wales and further develop its technology as it focuses on reaching gigawatt scale manufacturing.
Startups Look for Ways to Bring Down the Cost of Green Hydrogen
Companies are pouring a lot of money into the idea that hydrogen can help decarbonize the fossil-fuel-based economy. One drawback to hydrogen as a form of green energy, however, is that nearly all of the world’s hydrogen is produced in a greenhouse-gas-intensive process: heating natural gas with steam to split it into hydrogen and carbon dioxide. This type of hydrogen is known as gray hydrogen, or sometimes blue hydrogen if the factory has carbon-capture technology.
Green hydrogen currently costs between approximately $3 per kilo and $26 per kilo, according to data from S&P Global. The Energy Department has said it needs to cost about $1 per kilo to unlock new industrial applications. Closing that gap with current technology depends on renewable electricity becoming a lot cheaper. The Hydrogen Council, an industry group, says the cost of making hydrogen with electrolyzers could fall to $1.40 a kilogram by 2030 in the right circumstances, such as renewable electricity being available for as little as $13 per megawatt hour.
