DUWAAL hub & satellite Wieringerwerf

Publieke samenvatting / Public summary

The integration study W2H2 concluded that offshore wind producing H2 can be directly used as energy and is cost-effective with electricity as an energy carrier. Further investigation with TU Delft and in the SBIR study showed that by optimisation twice the wind energy can be yielded at a lower cost than with electricity as a carrier. The integration study HPS showed the cost-effectiveness of high-pressure storage & distribution for wind to H2 for mobility. The TU Delft showed the impact of an integrated supply chain, combing different production and offset locations with an integrated storage and distribution system. The Dutch grid has reached its limits. The EU set a target of 5.2% H2 in mobility in 2030. It is time for wind to H2 to mobility demonstration projects.

The Duwaal Hub & Satellite Wieringerwerf is a field lab that aims to demonstrate process and product innovations across the whole value chain from wind to wheel. The chain is designed and optimised in an integral way. This reduces cost, increases efficiency, and will make H2 a cost-effective fuel for zero-emission mobility. The new and integral value chain offers opportunities for new business models. A network of satellites increases the reach of H2 to more potential clients and improves the distribution efficiency.

Korte omschrijving
The project will have a 5 MW electrolyser on which pulsed power will be applied to increase the efficiency of the electrolyser. The hydrogen will be transported via a 5 km pipeline to a hub station next to the A7 highway. There is a hydrogen refuelling station at the hub and a docking station to fill the intelligent high-pressure swappable storage at 100 MPa (iBundles), which will be developed in this project. The hydrogen will be transported to, in this project-developed, satellite stations based on the cascade from the iBundles. The objectives of these satellite stations are to reduce the cooling demand and the return pressure by developing a filling protocol. This project creates a network of filling stations that are being leased out based on a scalable capacity (demand) per day. HYGRO Energy owns and operates the chain. HYGRO technology is the system integrator with several strategic suppliers. Avia-Marees provides the different locations and will actively stimulate the demand for hydrogen. NHN will take care of promotion and knowledge dissemination. TNO will validate all expected energy and efficiency gains.

The results of the project will be: 1) a significant reduction in CO2 emissions in the Netherlands, 9485 tons CO2/year 2) efficiency improvements and cost reductions in the value chain from wind to wheel of hydrogen 3) more affordable green hydrogen in €/kg, to reach cost parity of hydrogen with diesel 4) 525.000 kg/year of green hydrogen available for the transport sector at hydrogen refuelling stations in Noord-Holland 5) validating the large-scale application of pulsed power to increase the efficiency of electrolysers by 10% 6) validating the efficiency improvement of hydrogen distribution using network logistics with iBundles
