Clean energy, sustainable jobs and a greener future for us all

Plans to power the proposed Flotta Hydrogen Hub are being investigated by Offshore Wind Power Limited (OWPL), a consortium formed by Macquarie’s Green Investment Group (GIG), TotalEnergies and Scottish developer Renewable Infrastructure Development Group (RIDG).

The proposal is being explored by OWPL in partnership with Repsol Sinopec, the Flotta Terminal owner, and Uniper, a leading international energy company and pioneer in the field of hydrogen.

The idea is supported locally by EMEC Hydrogen which has spearheaded Orkney’s leading position in green hydrogen production.

The proposal brings together some of the world’s largest energy companies together with international expertise on hydrogen production, green infrastructure investment, project development and low carbon innovation - all working together to investigate the production of large-scale green hydrogen production from offshore wind.

The partners bring significant financial expertise, technical capability, and a track record in successful project development.

This makes the Flotta Hydrogen Hub a compelling proposition to generate clean energy, sustainable jobs and a greener future for us all.
