Green hydrogen – made from the electrolysis of water, using renewable energy – is totally carbon-free and could one day replace fossil fuels used in a range of applications, from steelmaking to marine transportation. But today, the use of this low-carbon fuel is hampered by the fact that it is more expensive than fossil fuels and other forms of hydrogen, which are created using more carbon-intensive processes. Australian startup Hysata says it has overcome this problem. The company this month said it had created a technology called a capillary-fed electrolysis cell that has 98% energy-to-hydrogen conversion efficiency. That is enough to bring the cost of green hydrogen down to less than 1.50 USD a kilo once the technology scales up, Hysata claims. The price point is cheaper than any other form of hydrogen today, and comparable with fossil fuels such as diesel. “Hysata’s ultra-high efficiency electrolyser will make green hydrogen competitive years earlier than generally assumed, accelerating global decarbonisation and increasing energy security,” says Hysata. The next task for the company, a spinout from the University of Wollongong, which has financing from British investor IP Group and the Australian Clean Energy Finance Corporation, is to scale up the technology.
