Large-Scale Offshore Hydrogen Production and Pipeline Transport System

energyTestedTRL 6

Imagine a giant floating battery that turns seawater and wind into clean fuel right in the middle of the ocean. Instead of bringing electricity to land through expensive cables, this system makes hydrogen gas on a barge and sends it through pipes. It is like moving a chemical factory offshore to capture the strongest winds available.

The business problem

What needed solving

Transporting electricity from offshore wind farms to land is expensive and inefficient. There is a need for a way to convert that energy into a transportable fuel at the source to reach the 10 Mt clean hydrogen goal by 2030.

The solution

What was built

A 10MW offshore hydrogen production system installed on a retrofitted jack-up barge, including desalination and pipeline export components.

Business applications

Who can put this to work

Energy Infrastructure
enterprise
Target: Offshore Wind Farm Developer

If you are a wind farm developer dealing with grid congestion and energy loss during transmission — this project developed a 10MW offshore production system that converts wind power directly into hydrogen for pipeline export.

Industrial Chemicals
enterprise
Target: Heavy Industry Plant

If you are a chemical plant dealing with high carbon emissions from traditional hydrogen sources — this project developed a supply chain from offshore electrolysers to onshore clients that provides renewable hydrogen.

Maritime Engineering
mid-size
Target: Offshore Platform Operator

If you are a platform operator dealing with the need for sustainable fuel production at sea — this project developed a retrofitted jack-up barge concept that proves the technical sustainability of offshore electrolysis.

Frequently asked

Quick answers

What is the projected industrial scale of this technology?

The project starts with a 10MW demonstrator and uses that data to assess the feasibility of larger 300MW and 500MW offshore concepts.

When will this be available for commercial deployment?

The consortium intends to enable the deployment of commercial large-scale solutions as soon as 2028.

What is the cost or price of the system?

Based on available project data, specific pricing is not provided, but the project includes techno-economic assessments to prove commercial sustainability.

How is the intellectual property or licensing handled?

Based on available project data, the project produces exploitable results including detailed designs of replicable technologies, though specific licensing terms are not listed.

How does the hydrogen get from the ocean to the customer?

The system uses offshore hydrogen pipes to export the gas from the production unit to end-clients onshore.

Consortium

Who built it

The consortium is heavily industry-driven with a 78% industry ratio, consisting of 7 industrial partners and 2 SMEs across 6 countries. This composition ensures the project is focused on commercial viability, integrating the entire value chain from wind developers and electrolyser manufacturers to desalination and pipe specialists.
