22 Nov 2021: Vattenfall submitted an EIA Screening Opinion Request Report for a proposed hydrogen demonstrator project at Vattenfall’s Aberdeen Offshore Wind Farm (AOWF). An existing AOWF turbine, dubbed Hydrogen Turbine 1 (HT1), will be retrofitted by installing an extended transition piece platform to house hydrogen producing equipment and other associated infrastructure. The hydrogen equipment installed on the turbine will comprise the electrolyser, desalination equipment and compressors. The platform to support this new infrastructure will be installed on the transition piece of the turbine, extending the current platform to provide sufficient area. From the turbine, a new subsea flowline would be installed, connecting to an onshore storage and offtake facility. Route options are under consideration, with a length range of 6.5 - 14.3 km. The flowline is anticipated to be a maximum of 8” internal diameter. The location of the onshore infrastructure for HT1 is yet to be finalised and is subject to ongoing site selection. Irrespective of location, the site will be up to a maximum of 0.5 ha in size, in close proximity (no more than 1 km) from the landfall. The HT1 facility is envisaged to be operational by 2024/5. The lifetime of the project is likely to be between 8-10 years, which is the lifetime of the electrolyser system. The current OWF is licenced until July 2043. Vattenfall have requested clarification of the consenting route for this new type of offshore infrastructure. It is understood that the required infrastructure is not considered an energy generating station and thus does not fall under the Electricity Act 1989. And the works should not significantly alter the project parameters under the existing AOWF consents.
