Dolphyn Hydrogen Phase 2 - Final Report

EXECUTIVE SUMMARY

The Dolphyn concept for the production of ‘green’ hydrogen at scale from offshore floating wind. The Dolphyn concept has been developed over the last 4 years.

This development has been accelerated under the Hydrogen Supply Competition, funded by the BEIS Energy Innovation Programme (2016-2021). During Phase 1 of the programme, the concept was compared to alternative centralised and decentralised options both onshore and offshore and was found to be the most economically advantageous solution for generating hydrogen at multi-GW scale. Subsequently a prototype design solution for ERM Dolphyn was developed to FEED stage.

Through the work completed in this phase (Phase 2), the project has progressively de-risked the design to the extent that we can move forward confidently to a 10MW unit FEED from the previous 2MW unit. This will enable us to build the first 10MW unit more quickly and will result in the development pathway for the first commercial Dolphyn wind farm (typically 100-300MW) being accelerated by up to 4 years. The project aim is to construct and operate the first 10MW unit by the end of 2024. The first commercial scale farms (100-300MW) are currently being planned and are expected to be operational from the late 2020s.
