Modern Hydrogen Requires Advanced Ionics Technology

How Does It Work?

Electrolyzers in the market today fall into two categories – hot and cold. Cold electrolyzers—like alkaline, AEM, PEM, and others—work with liquid water. They always require large amounts of electricity to coax a liquid into electrolysis, at least 40 kWh to make a kilogram of hydrogen, and often more than 50 kWh is needed. Worse yet, many of these systems require expensive platinum and iridium metals and exotic, delicate polymers. Meanwhile, hot electrolyzers such as solid oxide electrolyzers work with 800 °C superheated steam. By working with steam, the electricity requirements are significantly lower. But, making steam that hot requires extra energy to ‘step-up’ industrial steam to the required temperature. And what’s more, hot electrolyzers use delicate and expensive ceramics that drive up capital costs and reduce reliability.

Our magic is in the middle. Our Symbion Electrolyzers use process or waste heat across a wide temperature range—from 100 °C up to as hot as you can get it. By operating with steam, our electrolyzers tap into excess heat that is already available in industrial settings, lowering  electricity use in tandem, usually below 35 kWh/kg, with 30 kWh/kg possible. And what’s more, our technology uses abundant and widely available components to keep capital costs low – no expensive platinum-group metals, no iridium, no fluoropolymer membranes.

Symbiotic™ Electrolysis

Our technology is able to create the lowest-cost green hydrogen by tapping into existing process and waste heat sources at industrial facilities. This symbiotic relationship allows existing heat sources to help drive electrolysis. Built by a team that’s spent decades studying lithium-ion, sodium-ion and lead-acid batteries, fuel cells, electrolyzers, superconductors, and textiles, our platform’s innovation is in our patented electrode architecture. These electrodes, built from common materials in unique configurations, allow our electrolyzer to work without polymer membranes and most importantly, function using process heat across a wide range of temperatures.
