Australian startup Hysata, which says it has developed the world’s most efficient electrolyzer, has raised A$42.5 million ($29.4 million) in an oversubscribed Series A funding round. The money will be used to develop the company’s team and “develop a pilot manufacturing facility” for the innovative “capillary” technology, which it says will be able to deliver “the world’s lowest-cost green hydrogen” due to its superior efficiency. . In simple terms, the biggest element of the levelised cost of green hydrogen (LCOH) is the cost of renewable electricity used, so that less power is required for the electrolyzer to produce every kilogram of H 2 the lower the LCOH. Hysata says the capillary-fed electrolyzer (CFE) only requires 41.5 kWh of electricity per kg of hydrogen. The industry benchmark for highly efficient electrolyzers is 50kWh/kg. “Hysata’s electrolyzers operate at 95% system efficiency (41.5 kWh/kg), delivering a huge leap in performance and cost over older technologies, which

FRANKFURT/MARBURG/BASEL. In 2013, a team of microbiologists led by Professor Volker Müller of Goethe University Frankfurt discovered an unusual enzyme in heat-loving (thermophilic) bacteria: hydrogen-dependent CO. 2 HDCR reductase. It produces formic acid (formic) from hydrogen gas (H 2 ) and carbon dioxide (CO 2 ), and in the process, hydrogen transfers electrons to carbon dioxide. This makes HDCR the first known enzyme to directly utilize hydrogen. On the other hand, all the enzymes known to date that produce formic acid took a detour: they obtained electrons from soluble cellular electron transfer agents, which for their part accepted electrons from hydrogen with the help of other enzymes. The bacterium Thermoanaerobacter kivui thrives away from oxygen, for example in the deep ocean, and uses CO 2 and hydrogen to produce cellular energy. HDCR from Thermoanaerobacter kivui consists of four protein modules: one that cleaves hydrogen, one that produces formic acid and two small

Using data collected more than two decades ago, scientists from the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, have compiled the first complete map of hydrogen abundance on the Moon’s surface. The map identifies two types of enhanced hydrogen-containing lunar material and corroborates previous ideas about lunar hydrogen and water, including the finding that water likely played a role in the formation and solidification of the Moon’s native ocean-magma. David Lawrence, Patrick Peplowski and Jack Wilson of APL, along with Rick Elphic of NASA’s Ames Research Center, used orbital neutron data from the Lunar Prospector mission to create their map. The probe, deployed by NASA in 1998, orbited the Moon for a year and a half and sent back the first direct evidence of an increase in hydrogen at the lunar poles, before hitting the lunar surface. When a star explodes, it releases cosmic rays, or high-energy protons and neutrons that travel through space at nearly the sp

Australian researchers have found a new way to safely separate, store and transport large amounts of gas that could be the missing piece of the puzzle for renewable hydrogen. The number of renewable hydrogens is huge in Australia’s net zero emissions plan – particularly in the hard-to-decarbonise industrial and heavy transport sectors. But storing and transporting large amounts of gas for practical applications remains a major challenge. A team from Deakin University’s Institute for Frontier Materials (IFM) in Melbourne says it has found a new mechanochemical way to separate and store gases, which is safe, uses less energy than traditional methods and produces no waste. The team said the breakthrough, detailed in the journal Materials Today, was a departure from accepted wisdom on gas separation and storage and had to be repeated 20 to 30 times before it could be trusted. “We were very surprised to see this happen, but every time we kept getting the exact same results, it was a eur

No one can accuse Andrew Forrest of lacking ambition. The billionaire entrepreneur made a fortune by dismantling the West Australian iron ore duopoly of mining powerhouse BHP Group and Rio Tinto – something skeptics say can’t be done. He now wants to make another fortune by helping save the planet and turning the mining company he controls — Fortescue Metals Group — into a global leader in renewable energy, and green hydrogen in particular. During a recent visit to London for the FT Hydrogen Summit, Australia discussed its plans for FMG, denounced companies promoting blue hydrogen, and questioned Tesla’s Elon Musk’s green credentials. Forrest reckons his green energy unit, Fortescue Future Industries, could go from a standing start to producing 15 million tonnes of green hydrogen per year by 2030 — just 5 million tonnes less than the goal set by the European Commission over the same period. Elon Musk knows that almost every time a Tesla is plugged into almost every grid in the world, i
