NEW H-LEAF TECHNOLOGY FOR GREEN HYDROGEN GENERATION

H-LEAF is a project that investigates new components, materials, coatings and also new, more sustainable and scalable processes for the production of green hydrogen. The objective is to overcome the current limitations in the supply of materials and the production costs of green hydrogen, which are key elements for driving the energy transition in Spain.

Rotimpres, a printed electronics manufacturer, is part of the H-LEAF consortium, an innovative initiative for the research and development of advanced technologies in the production of sustainable hydrogen, working closely with the project partners to develop a PEM (Proton Exchange Membrane) electrolyzer. This technology is based on a new national patent, positioning Spain at the forefront of innovation in the sector.

The project focuses on exploring new electrode and membrane designs that incorporate materials with low environmental impact. By using advanced industrial printing techniques, H-LEAF is committed to scalable and sustainable processes, eliminating the use of perfluorinated chemicals (PFAS). This approach not only responds to current environmental demands, but also improves the safety and economic viability of green hydrogen production.

In addition, the project promotes interdisciplinary collaboration to integrate innovative coatings and materials into electrolysis technologies, thus ensuring optimal energy efficiency and cost reduction in the long term. This initiative contributes significantly to accelerating the energy transition in Spain, making the country a benchmark in sustainable solutions and emerging hydrogen technologies.

H-LEAF is also developing new bipolar plates using technologies such as stamped stainless steel substrate and 3D printing with recycled titanium powder, as well as advanced corrosion protection coatings. These plates will replace the current ones, reducing costs and allowing mass production.

In addition, the project addresses hydrogen compression using a novel piston system with advanced materials.

The final result will be an advanced demonstrator, reflecting the consortium's know-how and reaching a TRL 6, with an electrolyser power of up to 1 kW validated on a test bench. This demonstrator will allow the final characteristics of the new system and components developed to be evaluated.
