Do you believe transitioning to new green energy technologies will effectively lower future energy costs?
H2Pro has transitioned its proprietary decoupled water electrolysis technology from a 0.5 MW pilot module in Israel to planned 5 MW and 25 MW demonstration plants in Spain. This marks the company's move toward scaling green hydrogen production systems capable of utilizing intermittent renewable energy.
Why it matters
By decoupling the hydrogen and oxygen production cycles, the system aims to improve efficiency and flexibility when paired with variable solar power. This transition is intended to prove the commercial viability of low-cost, green hydrogen production at scale.
The system utilizes membrane-less decoupled water electrolysis to generate hydrogen using intermittent solar power. The pilot module currently produces 200 kg of hydrogen daily at a 0.5 MW capacity, with future plans targeting scaling to 50 MW and 150 MW.
The players
H2Pro
A developer of E-TAC (Electrochemical-Thermally Activated Chemical) water splitting technology designed to produce green hydrogen at a lower cost than conventional PEM electrolyzers.
The details
The technology separates the hydrogen and oxygen evolution steps, which are traditionally performed simultaneously in standard electrolyzers. By eliminating the membrane typically used to prevent gas mixing, the system can operate with greater flexibility under fluctuating power inputs. The Tziporit facility relies on direct solar integration to drive these production cycles.
Timeline
September 29, 2026: The company confirmed its expansion plans into the Spanish market.
The Tech Race
The deployment of these modules represents a move to compete directly with established PEM water electrolysis technology. Scaling from a 0.5 MW footprint to 150 MW remains a significant engineering hurdle for any new hydrogen production architecture.
The transition to Spanish demonstration sites marks a move toward larger industrial output for chemical and gas sectors. The actual impact on hydrogen market pricing remains subject to the success of the 5 MW and 25 MW plant construction phases.
The takeaway
The move from a 0.5 MW pilot to 25 MW plants indicates a push toward industrial validation for decoupled electrolysis. Observers should track the completion timelines of the Extremadura and Tarragona sites as a benchmark for the technology's scalability.
