Imagine a water-splitting machine that works like a high-pressure cooker, using extreme heat and pressure to make hydrogen much faster. By removing the expensive internal membrane and using a special flow of water, it cuts down on energy waste. It even explores using wastewater instead of pure water to keep things sustainable.
Current green hydrogen production is too expensive (5-8 €/kg) and energy-intensive, relying on critical raw materials and membranes that limit durability and efficiency.
A laboratory-scale (TRL4) membrane-less alkaline electrolyser including a single cell and a 5-cell stack designed for supercritical water conditions.
If you are an industrial gas producer dealing with high production costs of 5-8 €/kg H2 — this project developed a supercritical electrolyser that targets a competitive cost of 2-3 €/kg H2.
If you are a chemical plant operator dealing with high energy consumption for hydrogen — this project developed a membrane-less system that improves energy efficiency to 42 kWh/kg H2.
If you are a wastewater facility dealing with costly waste streams — this project developed a system that uses wastewater as an electrolyte for hydrogen production.
The technology aims to reduce production costs from the current 5-8 €/kg H2 down to a competitive 2-3 €/kg H2.
The project validates results at a laboratory scale (TRL4) using a single cell and a 5-cell stack.
Based on available project data, specific IP or licensing terms are not disclosed, though the consortium includes three industrial partners.
The membrane-less configuration and supercritical conditions increase system lifetime, targeting a degradation rate of less than 1% per 1000 hours.
The project period runs from 2024-01-01 to 2027-06-30.
The consortium is heavily industry-weighted with a 60% industry ratio, consisting of 3 industrial partners, 1 university, and 1 research center across 3 countries (DK, ES, IT). This structure suggests a strong focus on commercial viability and practical application, with a mix of SME and larger industrial players involved in the development of the test bench and stack.
