Study W2H2 Research of offshore wind hydrogen

In 2016-2017, together with ECN part of TNO, Energy Valley, Energy Expo and Composite Agency, HYGRO examined the future of green hydrogen, really by asking two questions:

  1. If wind energy is converted to hydrogen in an offshore wind turbine and is then brought ashore by means of pipe lines, how does this relate to offshore electricity when it comes to cost price and energy yield?
  2. If large volumes of hydrogen are brought ashore, where will hydrogen have the highest value and how does this relate to the cost price?


The further offshore, the higher the grid connection costs of wind farms. On average, the connection capacity is used for 50%. In case of full exploitation (strong wind), the price for electricity is low due to excess supply. It seems plausible that the costs of electrolysis and hydrogen transport are lower than those of an electrical grid connection. Added advantages are the possibility of buffering and the higher value per MWh if the hydrogen gas is used in the mobility sector.

Study HPS

This study supervised by HYGRO was conducted by the following parties: NEN, GP GROOT, Toyota Material Handling, SchipCo, E-trucks Europe and Composite Analytica.

Objective of system integration study "HPS"

Objective of the study was to find and optimise an integrated and standardised solution for transport and distribution in order to make the cost price per kilo hydrogen from wind turbines to different end users as low as possible. Hydrogen can eventually be supplied to different types of users, and the core question therefore is which laws and regulations must be complied with. The lower the cost price for the transport and distribution of hydrogen from wind to the end user, the quicker the hydrogen market will achieve momentum.

Integrated and standardised solution between wind & wheel

A large part of the cost price of hydrogen for the end user lies in transport and distribution, “from production to tank”. Type of tank, performance weight hydrogen/weight tank, pressure, temperature and regulations for hydrogen play an important role in that cost price. In the current chain, hydrogen changes a few times in relation to tank, pressure and temperature. By integrating and standardising the different sections of this chain, it should be possible to lower the cost price for this part of the chain.
