Tobe Energy is developing a new class of electrolyzers that split water into hydrogen and oxygen. According to the company, their membrane-free system reduces equipment costs by up to 75% and will reduce heat generation, which is a significant source of inefficiency in traditional systems. This is achieved through the use of advanced power electronics that control a high-voltage, low-current system, new anode and cathode configuration and the elimination of exotic materials. Tobe's electrolyzer is currently in the experimental prototype stage and costs $446 per kilowatt (kW), that is 45% less than the cheapest of other leading electrolysis technologies, such as alkaline, proton-exchange membrane, solid oxide and anion exchange systems.

SunFire manufactures solid oxide electrolysis cells (SOECs) that produce clean hydrogen using high-temperature electrolysis. These electrolyzers split steam into hydrogen and oxygen at temperatures of approximately 800°C, using electricity and heat to achieve electrical efficiency 25-30% higher than alkaline or PEM electrolyzers. They reduce energy consumption by utilizing waste industrial heat, reducing the levelized cost of hydrogen for large-scale production. Sunfire systems are used in industrial projects, such as the world's largest multi-megawatt solid oxide electrolysis complex at the Neste refinery.
