H2Pro is developing a membrane-free, phase-separated hydrogen electrolyzer (DWE) that enables producing the most affordable and truly green hydrogen. It connects directly to renewable energy sources, reducing production costs. The DWE operates in two phases. In the first phase, renewable electricity enters a bifunctional electrode, where it reduces water molecules, producing hydroxide ions and hydrogen molecules. Meanwhile, to complete the electrochemical circuit, a counter electrode reacts with hydroxide ions, producing water molecules and charging the electrode. As hydrogen is formed, it flows into a separator tank. In the second phase, the charged electrode discharges, while oxygen is formed at the bifunctional electrode. The oxygen flows into a separate tank. When the battery electrode is completely discharged, the cycle begins again from phase 1. H2Pro is currently implementing a 0.5 MW pilot project.

Ohmium designs, manufactures and installs reliable and cost-effective proton-exchange membrane electrolyzers for producing high-purity hydrogen under pressure. These energy plants use water and renewable energy to produce clean hydrogen and are easily scalable from megawatts to gigawatts thanks to their modular design. The electrolyzer uses tap water from an on-site source, purified through filtration, reverse osmosis and ion exchange for deionization, making it suitable for electrolysis. The company's cloud software ensures continuous global remote monitoring and maintenance of the system.

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.
