An independent study by the Carbon Trust has found that wet storage should be treated as a core phase of floating wind farm development.
Published in March 2026, the study was carried out on behalf of 17 leading international offshore wind farm developers and examined how wet storage strategy affects timelines, cost and delivery across floating wind projects.
Via the study, sites offering multi-use wet storage capability were shown to enable more efficient use of storage space, cutting project timelines and delivering savings across the whole development. Most notably, the study found that total installation time could be reduced by 50% compared with a traditional project that does not use wet storage.
Translated into project economics, those time efficiencies could result in savings of c.£458 million across the sector, according to the study, alongside a reduction in the Levelised Cost of Energy (LCOE) of around £15/MWh – savings that will result in lower costs for UK taxpayers and consumers.
The Carbon Trust’s findings reinforce wet storage’s critical position in floating wind development – as an enabler of on-time, cost-effective delivery that needs to be planned for, and resourced, from the outset.
