Neology is developing a system that converts liquid ammonia into hydrogen and then into electricity using fuelcells, with water being the primary byproduct. The process involves an "ammonia cracker"- a device that splits ammonia into hydrogen and nitrogen. The hydrogen is then fed into a fuelcells to generate electricity, while nitrogen, a harmless component of air, is released. The technology is designed for applications where battery-electric solutions may be ineffective, particularly for heavier vehicles, long-term operation, or in low-temperature environments. The resulting hydrogen can also be used in a variety of other ways.

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.

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.
