The OYSTER project will lead to the development and demonstration of a marinized electrolyser designed for integration with offshore wind turbines. Stiesdal will work with the world’s largest offshore wind developer (Ørsted) and a leading wind turbine manufacturer (Siemens Gamesa Renewable Energy) to develop and test in a shoreside pilot trial a MW-scale fully marinized electrolyser. The findings will inform studies and design exercises for full-scale systems that will include innovations to reduce costs while improving efficiency. To realise the potential of offshore hydrogen production there is a need for compact electrolysis systems that can withstand harsh offshore environments and have minimal maintenance requirements while still meeting cost and performance targets that will allow production of low-cost hydrogen. The project will provide a major advance towards this aim. Preparation for further offshore testing of wind-hydrogen systems will be undertaken, and results from the studies will be disseminated in a targeted way to help advance the sector and prepare the market for deployment at scale. The OYSTER project partners share a vision of hydrogen being produced from offshore wind at a cost that is competitive with natural gas (with a realistic carbon tax), thus unlocking bulk markets for green hydrogen (heat, industry, and transport), making a meaningful impact on CO2 emissions, and facilitating the transition to a fully renewable energy system in Europe. This project is a key first step on the path to developing a commercial offshore hydrogen production industry and will lead to innovations with significant exploitation potential within Europe and beyond.

150 trucks from three European truck OEMs, the Volvo Group, Daimler AG and IVECO will be deployed across eight EU member states. Each company, will develop and deploy 41-44 tonne articulated trucks which are specified for the longest haul operation (ranges over 600km). The trucks will be deployed with over 20 truck operators and operate in a wide range conditions and day-to-day operations across 8 European member states. The trucks will operate on a new network of high throughput hydrogen refuelling stations, designed specifically for trucks (installed by Shell, OMV, TOTAL, Everfuel and Linde). These will be installed to cover the major TEN-T transport corridors from North to South Europe, with an initial focus on the regions where the vehicles are manufactured (to enable the high level of on-road support that the OEMs’ customers rely on). The stations will be supplied using green hydrogen from a network of 8 new large electrolysers producing green hydrogen consistent with RED II requirements, with associated Guarantees of Origin. The project will create an extensive technical, economic and attitudinal dataset which proves the viability of hydrogen as a solution to decarbonising road freight. This will be analysed by research partners, SINTEF, VTT and Element Energy to create easily interpreted public report on the performance of the fleet. The results will be disseminated to an audience of: policy makers (to encourage policy change to favour hydrogen truck deployment), truck operators (to enable future uptake) and the wider hydrogen industry (to underpin supply chain investment). These activities will contribute to accelerating the rate and scale of uptake of hydrogen fuelled vehicles in Europe, preparing the policy, fuelling network and end user acceptance for the first series production of these OEM vehicles (at the scale of 1,000’s per year per OEM) from as early as 2026 and full industrialisation (10,000’s per year per OEM) around 2030.

Hydrogen Offshore Production for Europe (HOPE) intents to pave the way for the deployment of large-scale offshore hydrogen production. To this aim, HOPE will design, build and operate the first offshore hydrogen production demonstrator of 10MW by 2025 in an offshore test zone near the port of Oostende in Belgium. The two-years demonstration of a mid-scale concept on a retrofitted jack-up barge will prove the technical and commercial sustainability of renewable offshore hydrogen production, export by pipelines and supply to end-clients onshore. It will also provide an extensive experience to assess the feasibility of 300MW and 500MW offshore concepts. The experience gathered by the consortium members and the maturity levels reached at the end of the project will enable the deployment of commercial large-scale solutions as soon as 2028. HOPE gathers a unique consortium of European players with cutting-edge expertise across the whole hydrogen value chain: an offshore wind power developer, a renewable hydrogen producer, an electrolyser manufacturer, a desalination solutions manufacturer, an offshore hydrogen pipes manufacturer, a research centre, a regional development agency, a strategic consultancy and a renewables communication agency. HOPE will produce a large range of exploitable results including not only detailed designs of replicable offshore hydrogen technologies, operational data and resulting analyses from a first-of-a-kind project but also pre-feasibility studies and techno-economic assessments of two large-scale concepts. Through an ambitious dissemination and exploitation plan, the consortium intends to accelerate the deployment of large-scale offshore hydrogen solutions to contribute to reach the 10 Mt of clean hydrogen produced in Europe by 2030 to decarbonize the European economy and reach our climate goals.

REFHYNE II will install a 100MW PEM electrolyser at Rheinland refinery in Cologne, Germany, using renewable power to produce green hydrogen and oxygen, which will be fed-in to the existing refinery networks to decarbonise refinery operations. The electrolyser will be based on a state of the art 5MW PEM stack integrated into pre-engineered 20MW electrolyser trains, with factory assembled balance of plant to reduce the amount of bespoke work required to integrate electrolysers into new sites. The project will be delivered by the same team responsible for the REFHYNE project that has installed a 10MW PEM electrolyser at the same site, exploiting the experience of the consortium to deliver a timely and cost-effective project. REFHYNE II will achieve a viable business case for large-scale electrolysis at refineries by valorising the hydrogen and oxygen streams in the refinery and receiving RED credits for the hydrogen produced, while minimising the cost of hydrogen through improvements in efficiency and capital cost. A research task will explore the upgrading of waste heat to higher temperatures for use in the refinery, to further improve the business case. Power will be sourced through novel PPAs with named renewable plants. Emissions avoidance will be achieved by displacing the hydrogen currently produced on-site through SMR and adapting the refinery to allow the electrolyser to act as a flexible load and hence contract direct with renewable generators, to increase renewable penetration into the grid. Research work packages will support the deployment of 100MW+ scale electrolysers at refineries and industrial sites across Europe and enable GW-scale electrolysis systems to be implemented. Finally, a thorough dissemination work package will exploit the results of the project by delivering key messages to target audiences, and supporting three fast follower sites (of which at least two will be located in EU13 countries) to rapidly replicate the results of the project.

HYCELAND is a Small Hydrogen Valley project in Iceland, which will produce hydrogen to serve end users across mobility, industry and power sector applications. The project is being led by Landsvirkjun (the national power company of Iceland) in partnership with Linde (one of the world's leading industrial gas suppliers), who have established a consortium of partners to cover the entire value chain.
