Hysata develops ultra-high-efficiency hydrogen electrolyzers that intend to achieve the lowest cost of hydrogen. Thanks to high efficiency in an inherently simpler, cheaper and modular system (according to the company) its electrolyzer achieves 95% efficiency, significantly exceeding the International Renewable Energy Agency's 2050 efficiency target. Hysata's electrolyzer design is based on two key innovations: an ultra-low-resistance separator and bubble-free operation. Together, these factors reduce cell resistance and make the cell highly efficient. With the support of leading global strategic and financial investors, Hysata is rapidly moving toward multi-gigawatt production.
