Study W2H2 Research offshore wind – hydrogen

We carried out a research towards the future of sustainable hydrogen together with ECN part of TNO, Energy Valley (now Composite Analytica) Energy Expo and Composite Agency, by asking two questions:

  1. When in an offshore wind turbine, the wind energy is converted into hydrogen and brought to land via pipelines; how does this relate to the cost price and energy yield of offshore electricity?
  2. When large amounts of hydrogen are taken to land, at what point has hydrogen the highest value and how does it relate to the cost price?

The trigger 

The further offshore, the higher the costs of grid connections for the wind farms. The connection capacity is used for approximately 50%. At full use (strong winds) the electricity price is low, due to oversupply. It seems plausible that the costs of the electrolysis and the hydrogen transport are lower than an electricity grid connection. The extra advantage is the possible buffering and the higher value per MWh if the hydrogen gas is applied in the mobility sector.

Study HPS

This study has been conducted headed by HYGRO and carried out by the following parties: NEN, GP GROOT, Toyota Material Handling, SchipCo, E-trucks Europe & Composite Analytica.

Aim of the system integration study ‘HPS’

The aim of the project is the search and optimisation of an integrated and standardised solution for transport and distribution to lower the cost price per kilo hydrogen of the wind turbine to the various end users. In the end hydrogen needs to be supplied to different types of end users and the key question is with what rules & regulations need to be complied with. The lower the cost price of the transport & distribution of the hydrogen from wind to end-user, the sooner the hydrogen market will flourish.

An integrated and standardised solution between wind & wheel

For the end user the biggest part of the cost price of hydrogen is in the transport and distribution, “production to tank”. The type of tank, performance weight hydrogen/weight tank, pressure, temperature and regulations for hydrogen, play a key role to determine that cost price. Hydrogen changes several times of tank, pressure and temperature in the current chain. By integrating and standardising the various parts in the chain, the cost price in that part of the chain, could be easily lowered.
