Hysata, an Australia-based company, is pioneering advanced high-efficiency electrolysis technology to produce green hydrogen at scale. Their unique capillary-fed alkaline electrolyser aims to achieve higher energy efficiency and lower costs compared to other methods.
Recently, the company secured a significant $111.3 million USD investment led by bp Ventures and Templewater, with strong support from major strategic and financial investors including IP Group Australia, Kiko Ventures, Virescent Ventures, Hostplus, Vestas Ventures, and BlueScopeX.
The company also welcomed new major strategic and financial investors, including POSCO Holdings, POSCO E&C, IMM Investment Hong Kong, Shinhan Financial Group Co., Twin Towers Ventures, Oman Investment Authority’s VC arm IDO, and TelstraSuper.
Hysata plans to utilize the funding to enhance production capacity at its renowned beachside manufacturing facility in Wollongong, New South Wales, and to further advance its technology as it strives to achieve gigawatt-scale manufacturing.
“Our mission at Hysata is to accelerate the deep decarbonization of hard-to-abate sectors such as steel, chemical manufacture, and heavy transport by delivering the world’s most efficient, simple, and reliable electrolyzers. With high-efficiency, intrinsically low capex and a mass-manufacturable design, Hysata aims to drive down the levelised cost of hydrogen,” Hysata CEO, Paul Barrett, said.
“This funding round, backed by a world class syndicate of investors, demonstrates the game changing impact Hysata is having on the green hydrogen landscape. It will strengthen our team and enhance our capabilities, as we propel towards widespread commercial availability.”
The International Energy Agency has emphasized the urgent need to transition existing hydrogen use to low carbon options and to expand its application in heavy industry and long-distance transport to meet climate goals.
Hysata’s capillary-fed electrolyzer operates at 95% efficiency and only uses 41.5 kWh of energy to produce a kilogram of hydrogen. This significantly reduces operational costs for hydrogen producers and also lowers CAPEX by being more cost-effective to install and operate. The end result is the production of the cheapest green hydrogen available.
Hysata’s innovative design, initially developed by scientists at the University of Wollongong, aims to eradicate bubbles of hydrogen and oxygen gases in the electrolyte fluid between the anode and cathode. By preventing the formation of bubbles, which are non-conductive and can hinder electrode exposure to the electrolyte, Hysata’s design reduces system resistance and minimizes energy wastage.
The unique design of Hysata ensures that the electrolyte remains at the bottom of the device and can be drawn up through a porous, hydrophilic separator situated between the electrodes. This configuration allows each electrode to have full, direct contact with the electrolyte on the inner side, while maintaining a dry chamber on the outer side.
The innovative design allows the water to be split efficiently with minimal resistance, resulting in a significant increase in overall efficiency. Hysata claims that lab tests have shown up to 98% efficiency, suggesting that a real-world efficiency of 95% is achievable.xx
Hysata’s electrolyzers have the potential to achieve energy efficiency well above the International Renewable Energy Agency’s 2050 target when deployed at scale.
