Hymeth aims to use resources wisely by offering the most efficient clean and sustainable energy solutions, by using green hydrogen. Hymeth will change the way we consume energy going from polluting and non-sustainable sources to a clean and green environment. Green Hydrogen production is very expensive (as electrolyzers require platinum- or iridium-based catalyst), energy inefficient, large in size and they only compress hydrogen gas up to 350bar. Hyaeon™ is a low-temperature alkaline electrolyzer that is compact, lightweight, and supports high-pressure electrolysis. It includes radical innovations: a new non-precious alloy electrocatalyst, is capable of delivering highly compressed gas, and it's lightweight and compact electrolyzer reduces the space required.
