Economic and Efficient Electrolytic Hydrogen production

Project: Research

Project Details

Description

The overall aim of EEEHy is to generate the knowledge, in terms of materials, microstructures, production processes, as well as stack and system design that will result in a game-changing electrolyzer prototype based on high temperature and pressure alkaline electrolysis cells (HTP-AEC).

Key findings

In Work Package 7, we made an exploitation strategy for the HTP-AEC technology. This covered a detailed market analysis for most suitable applications, and a plan for rolling out the technology.

The findings showed:
1) HTP-AEC is best suited for application processes requiring high temperatures, where the excess heat can be utilised.
2) The project showed promising technological potential, with efficiencies at stack level on 95 % i the lab.
3) Project developers and industrial customers value proff-of-scale when selecting electrolyzer suppliers. However, they also want to work with OEMs who have promising innovation pipelines. This indicate a need for OEMs to keep investing in R&D, even though their strategy is on scaling up existing PEM or Alkaline.
4) During the project period, electrolyzer OEMs refocused their strategy from technology development, to ramping up production capacity. Thereby, R&D investments were down prioritised.

Layman's description

The EEEHy project targets cost-efficient, large-scale storage of electricity as hydrogen produced by high-temperature, high-pressure, alkaline electrolysis.

Electrolytic hydrogen production is a key technology for the transition to a 100% sustainable electricity system where intermittent energy sources like solar and wind will play major role, as it enables storage of surplus electricity while providing a crucial link between the renewable electricity grid and the production of sustainable fuels and chemicals.
