Project Green H2 Accelerator

With the Green H2 Accelerator project, we contribute to making the energy supply more sustainable by means of green hydrogen. Within this project we develop, build and test a unique 200kW electrolysis system for the production of green hydrogen.

Combating climate change and reducing the use of fossil fuels requires a major energy revolution worldwide. Green hydrogen as an energy carrier is one of the pillars of this transition. The ambition in the field of hydrogen as an energy carrier is great and has yet to be largely realized. This requires scaling up to tens of gigawatts of electrolysis capacity in the coming years. This requires a huge increase in sustainably generated energy from the sun and wind. Due to the intermittent nature of these sources, continuity of supply and storage is a major challenge.

In the Green H2 Accelerator project, we are taking an important step in the development of hydrogen as an energy carrier. We do this by further developing stack’s AEM [Anion Exchange Membrane] electrolysis technology.

Cell surface

Within this valorisation project, we want to arrive at a prototype electrolysis cell with a surface area of 40 x 40 centimetres and a greatly improved performance based on an innovative production technology in two steps.

100 kW stacks

With the final cell, two stacks of 100 kW each with specific Unique Selling Points are built. Within this project, these stacks will be demonstrated in a test environment and in an operational environment in the form of a complete electrolysis system of 200kW. The demonstration on an operational scale will take place at the yet to be built solar park in the Ballumerbocht on Ameland.

The activities within the valorisation project are between TRL 5 and 7. The model of TRL’s [Technical Readiness Level] has been developed by NASA and indicates the phase of the development of a new technology.

The intended Unique Selling Points are:

– Controllability of the system from 0% to 100%
This makes the system ideally suited to combine with intermittent sources such as solar and wind energy.

– Startup speed of the system within one minute
This is also important for the combination with intermittent sources such as solar and wind energy.

– Comparable or higher efficiency than comparable technologies

This at both stack and system level (> 80% system efficiency)

– Low cost and fully recyclable (cradle to cradle).
We do this by making little or no use of precious metals such as iridium and platinum, a simpler assembly of the stack and a less complex Balance of Plant (BoP).
