Periodic Reporting for period 1 - REFHYNE II (Clean Refinery Hydrogen for Europe II)
Período documentado: 2021-10-01 hasta 2022-09-30
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 stacks integrated into pre-engineered 10MW electrolyser trains, with factory assembled balance of plant to reduce the amount of bespoke work required to integrate electrolysers into new sites. 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.
The overall objective of the project is to prove the technical and commercial viability of renewable-coupled electrolysis at the 100MW scale in a complex and representative industrial setting. A thorough campaign to extract and share learnings from the deployment will facilitate the rapid replication of the project across Europe and ensure the realisation of the project provides a pathway to GW-scale electrolysis across Europe, in line with prevailing European strategies.
- Reduce the capital cost of the installed electrolyser stack and the fully integrated system, through a combination of scaling-up and technology improvement
- Improvements at stack level to improve the overall electrolyser performance through concurrent increases in efficiency and current density
- Develop a pan-European supply chain with GW-scale electrolyser production capacity
- Demonstrate direct contracting between an electrolyser and a “New” renewable power supply portfolio (on- and offshore wind + solar), whilst optimising trading activities with regards to plant economics
- Produce green hydrogen at lower cost than has previously been achieved, to enable the business case for its use on an industrial scale
- Demonstrate a viable business case for the production of green hydrogen in a large-scale industrial setting
With the REFHYNE 2 project, we will increase the knowledge in, and accelerate deployment of integrating large scale electrolysers in industrial sites. Green hydrogen is one important element in the green transition in hard to abate industry sectors such as refineries.
