Wind-to-Hydrogen Toolkit

Wind-to-Hydrogen Toolkit is a collection of tools developed by researchers in the H-Wind, HyFloat1, and HyFloatComp projects at the MaREI Centre, University College Cork (UCC) to study the integration of offshore wind with the production, storage, and utilisation of hydrogen.

We expect that these tools will be of benefit to project developers, students, and other researchers to work on green hydrogen systems. As work is peer reviewed, we will release these tools for public use as a durable output of the H-Wind, HyFloat1, and HyFloatComp projects. See Published Tools below for the list of open source tools we have released.

H-Wind: Hydrogen from offshore wind

H-Wind is a MaREI Centre industry-led collaborative research project on the production of green hydrogen from offshore wind farms. Thanks to Ireland having one of the world’s best offshore wind resources, there is an extensive opportunity for green hydrogen to be generated through electrolysis from offshore wind farms in Ireland.

This three-year, multi-disciplinary project focusses on:

• Utilising green hydrogen as the interface between offshore wind energy, gas networks, electricity system, and markets, and to develop new markets for zero-carbon green hydrogen.
• Assisting Ireland in ensuring the delivery of the EU strategy on energy system integration, and to also help with the government’s 2050 targets.
• Suitable hydrogen hubs for the Irish, Celtic, and Atlantic Seas, which are necessary to meet the goal of this large-scale hydrogen production from offshore wind farms, along with hydrogen storage and transportation.
• The customer value chain, policy recommendations, hydrogen safety and procedures, and concepts for scalable and optimised offshore wind.

All of these factors will contribute to significantly replacing Ireland’s reliability on fossil fuels which will effectively reduce greenhouse gas emissions, along with securing the national energy supply and enabling the exploration of new energy export markets.

The H-Wind project is supported by a research grant from Science Foundation Ireland (SFI) under Grant No. 12/RC/2302 – P2 and by the industry consortium members: DP Energy, Equinor, ESB, and Gas Networks Ireland.

HyFloat1

HyFloat1: Concept development of floating offshore wind foundations coupled with hydrogen storage

Hydrogen produced from floating offshore wind energy will require innovative storage systems. The HyFloat1 project aims at developing new concepts for floating offshore wind foundations coupled with hydrogen storage. Several existing floating offshore wind foundations will be numerically assessed and modified for storing hydrogen. Converting offshore wind energy into hydrogen and storing it in the foundations of a floating offshore wind turbine is a novel approach that could reduce the levelised cost of energy for floating wind.

The HyFloat1 project is supported by a research grant from the Sustainable Energy Authority of Ireland (SEAI).

HyFloatComp

HyFloatComp: Novel design and manufacturing strategies for innovative offshore composite hydrogen tanks

HyFloatComp aims to develop advanced manufacturing and design approaches for offshore composite hydrogen tanks, which will play a crucial role in the energy supply chain from offshore wind energy to end users. These composite tanks offer flexibility and strength, allowing them to withstand hydrogen pressure and environmental loads. The manufacturing process will utilise laser-assisted tow steering, enabling variable geometry and precise production of the tanks, making them reliable and cost-effective. The project will focus on understanding the structural behaviour of variable angle tow composites under high-pressure hydrogen conditions.

The HyFloatComp project is supported by a research grant from the Sustainable Energy Authority of Ireland (SEAI).
