Aanleiding

As the development of offshore wind accelerates in the Netherlands, the share of intermittent renewable energy increases significantly in the electricity grid.

Once the volume of installed capacity of offshore wind will increase from 1 GW in 2020 towards 11 GW in 2030, the share of intermittent renewable power will be around 70%.

This will cause large challenges on the stability of the power grid and balance supply and demand. Furthermore, the capacity of the onshore grid can become a bottleneck by 2030, which prevents further acceleration of offshore wind deployment.

With wind parks being developed further offshore, the transmission of produced power via cables requires expensive high voltage AC or DC connections to shore. These costs increase over large distances from shore and at a certain point a trade-off should be made between the transmission of energy by electrons or molecules.

Doelstelling

The goal of the project is to build and test a 1 MW PEM offshore green hydrogen generation system on the Q13-A platform operated by Neptune Energy using seawater and green energy for the duration of one year.

Korte omschrijving

Figure 1 illustrates a simplified scheme of the project scope of work and division of work packages.

1. Work package 1 (WP1) covers the project coordination.
2. WP2 addresses the development of the electrolysis system, which will be installed and tested offshore.
3. Work packages 3 and 4 (WP3 and WP4) address the modifications and adaptations needed on Q13-A and P15 for the system to function.
4. Prior to the offshore test, an onshore integration and testing is included for risk reduction purposes (WP5).
5. Testing and operation of the electrolysis system offshore is covered in WP6.
6. In work package 7 (WP7), the consortium will perform the techno-economic and environmental assessment of the pilot and the business model for the scaled-up scenario.
7. Work package 8 (WP8) focuses on the mixing profile of the H2 in the natural gas system and the development of in-line measurement systems for H2 in a gas mixture.
8. In WP9, the project communication, dissemination, and exploitation is included.

Resultaat

World's first offshore pilot for green hydrogen production and transmission through the existing gas grid, as a stepping stone towards GW-scale offshore green hydrogen production.
