Dorset Green H2 - Private Wire HV Network Modifications

This project comprises of the installation of an electrolyser with a compressor directly connected to a solar farm that has operational capacity of 5MW with supplemental energy either coming from locally installed gas engines or the grid. The proposed 1 to 1.5 mega-Watt (MW) Proton Exchange Membrane (PEM) electrolyser will be installed on-site and used to produce green hydrogen, from a potable water feed and will be powered by the co-located solar farm - producing a carbon free fuel and energy storage opportunity that can be used to help decarbonise a number of downstream applications. Within this project, the green hydrogen will be compressed and filled into hydrogen trailers. This hydrogen is anticipated to be transported off-site for a variety of applications, however, neither of these distribution/use scenarios are included within this Tender. The new installation will be connecting to an existing 11 kV Private Wire network that is currently supporting a 7MW Landfill Gas Generation facility. This connection is designed to support a 6.8MVA Export Capacity and a 375 kVA Import Capacity. The Landfill Site, whilst equipped with 7MW of Landfill Gas Engines, only has only enough Landfill Gas to support the Generation of 1.8 MVA from the Landfill site. The existing Landfill Site Electrical System will require significant modification to make it suitable for the connection of the proposed Solar Farm.
