Whether you are a seasoned researcher or simply curious about the latest developments in your field, we believe that the posters will offer something of interest to everyone. So please join us at the conference and take advantage of this opportunity to learn and engage with your peers in industry and the academic community.
PO087: Does Storage Capability Improve Economics of Offshore Wind Projects?
Rasmus Juhlin, Senior Principal Engineer, Subsea 7
Abstract
Offshore wind (OW) is central to global decarbonisation efforts, yet recent market disruptions have challenged its economic viability. Fixed-bottom OW projects face rising costs due to supply chain constraints and financing pressures, while floating OW - though promising - remains expensive and technologically nascent. These challenges have led to auction failures most recently in Germany, but also in the UK, Denmark, and the US, highlighting the need for innovative solutions to improve project economics and grid integration. One such solution is co-locating OW farms with energy storage systems. This study explores the techno-economic potential of a novel hydro-pneumatic subsea energy storage system. Unlike lithium-ion batteries, this mechanical system offers longer-duration storage (4–12 hours), enabling OW operators to engage in short-term merchant markets and reduce curtailment. Over 5,000 business cases were modelled for 1,000 MW fixed and floating OW farms in the UK, assessing power ratings (50–500 MW) and storage durations. The analysis reveals that co-located subsea storage can enhance revenue streams and grid stability, offering a pathway to more resilient and profitable OW deployment.
