Pressurized Efficient Alkaline Electrolyser (PEACE)

PEACE is a research and innovation project funded under the EU Horizon Europe programme. It brings an innovative solution to the reduction of hydrogen production costs by developing a new, efficient alkaline electrolyser while utilising a two-stage pressurisation concept.


The reduction of emissions of carbon dioxide (CO2), represents a significant challenge within the EU Green Deal and for EU’s efforts against the ongoing climate crisis. This challenge is of outmost importance in order to achieve the goal of a climate-neutral continent by 2050. As early as 2030, the EU plans to reduce greenhouse gases emissions by at least 55%, necessitating the use of higher shares of renewable energy and greater energy efficiency. To meet these goals, the production of green hydrogen through electrolysis (powered by renewable sources) offers a viable solution.

The PEACE project focuses on developing high-pressure alkaline electrolysis technology to substantially reduce hydrogen production costs to enhance the competitiveness of the hydrogen economy. Furthermore, the project aims to enhance the integration of the hydrogen production with its subsequent utilisation within the chemical industry. Such an integration reduces costs and saves energy. PEACE will also conduct a life cycle assessment (LCA) to quantify the environmental impacts of its innovative technology.

Our objectives

We aim to contribute to a sustainable and low-emission European society by reducing the levelized cost of hydrogen (LCOH) through the development and demonstration of a 50kW low-temperature alkaline water electrolysis system capable of operating at pressures more than 50bar.
