NewHydrogen, Inc., developer of ThermoLoop, a technology that uses water and heat to produce the world’s cheapest green H₂, described its plan to replace expensive electrolyzers and win the renewable H₂ race.

NewHydrogen CEO Steve Hill said, “Today, using electrolyzers is the only commercially available way to split water to produce renewable H₂. Electrolyzers have dominated the headlines, but their reign may be coming to an end. The time has come to kill electrolyzers.”

“The renewable H₂ industry’s heavy bet on electrolysis is holding it back,” Mr. Hill continued. “Why? Because electrolyzers are old tech—expensive, inefficient, and fundamentally flawed. These 200-yr-old systems still depend on large amounts of electricity and face major cost and scaling challenges. Despite massive investment, they’ve struggled to deliver the cost reductions and reliability needed to help unlock the global H₂ economy.”

ThermoLoop is being developed to change that. Instead of electricity, ThermoLoop can use any source of heat to split water into H₂ and oxygen, making it a fundamentally different, and a more promising approach. By addressing key limitations that have dogged electrolyzers for decades, ThermoLoop has the potential to leapfrog the current state of the art and win the green H₂ race.

At the heart of ThermoLoop is its novel materials and novel reactions that keep the process running at nearly the same temperature—eliminating the energy losses of traditional thermochemical heating and cooling cycles. The company believes this can overcome a long-standing thermochemical challenge: how to scale without wasting energy. This approach enables continuous, 24/7 H₂ production wherever there’s heat and water.

Even when using large industrial heaters powered by electricity, ThermoLoop’s theoretical heat-based thermodynamic efficiency suggests it can outperform electrolyzers on a cost-per-kilogram basis. That can make ThermoLoop technology not only an alternative, but a direct threat to the electrolysis-first strategy dominating today’s H₂ buildout.

Mr. Hill concluded, “Relying on inefficient electrolyzer technology won’t get us to the projected $12-T H₂ economy. Other horses in the race that rely on massive tracts of land and part-time sunlight won’t get us there either. In my opinion, it’s ThermoLoop or bust. We believe ThermoLoop can offer a smarter path forward and has the potential to be the key to finally delivering on green H₂’s global promise.”
