HEDERA Project Develops Cost-Competitive PEM Electrolyzers for Industrial Hydrogen Production

The HEDERA project is addressing two key challenges in hydrogen production: the high cost and limited durability of PEM electrolyzers. Led by Instituto Tecnológico de la Energía (ITE) in Valencia, Spain, the initiative brings together Laurentia Technologies, Galvanizadora Valenciana, and Linkener to develop commercially viable solutions.

The project focuses on two primary innovations: advanced electrode formulations using catalytic ink techniques that reduce precious metal requirements, and a predictive degradation model powered by machine learning. The electrode designs use nano-scale platinum-group particles in polymer binders with green solvents and low-temperature curing processes.

The predictive model incorporates machine learning algorithms trained on accelerated life-cycle tests, accounting for variables such as current density, temperature fluctuations, and operational cycles that mirror real renewable energy integration. A digital twin of the pilot plant enables real-time optimization of hydrogen output, electricity costs, and equipment wear.

At ITE's demonstration facility, the technology is being tested alongside alkaline electrolyzers, hydrogen storage modules, and fuel cells under industrial load profiles. Funding comes from IVACE+i and the EU's FEDER regional development program, with the project targeting completion by 2026.

Industrial sectors including ammonia production and steel manufacturing are monitoring progress, as reduced electrolyzer costs could improve the economics of green hydrogen in decarbonization applications.
