Costain Group PLC Completes First Phase of Engineering Studies for Locating Onshore Facilities for Energypathways' Mesh Project EnergyPathways plc reported that Costain Group PLC has completed a first phase of engineering studies for locating onshore facilities for EnergyPathways' MESH project at Barrow-in-Furness, Cumbria. Costain evaluated a number of potential site locations and shortlisted them for further evaluation and front-end engineering and design. Costain is now progressing with a second phase of detailed engineering design work for the MESH onshore facilities. The MESH project, designated as a project of national significance by the UK Department of Energy Security and Net Zero (DESNZ) in September 2025, is an integrated long-duration energy storage project located in the east Irish Sea. It will be connected to Britain's energy network via new and existing pipelines and transmission lines. MESH will combine compressed air, natural gas and hydrogen storage within purpose-built offshore salt caverns and flexible medium-range gas field storage. EnergyPathways aims to develop a sustainable industry park at Barrow-in-Furness which over time may incorporate onshore facilities comprising: hydrogen and graphite production facilities; clean ammonia production facilities; energy storage operations base; connection infrastructure for the MESH offshore LDES and gas storage facilities; and onshore energy storage and industrial product export facilities. The development of these facilities will be dependent on EnergyPathways securing financing and planning approvals for the MESH development. The MESH project closely aligns with the UK's energy, industrial and economic growth strategies, alongside the UK's 2035 Critical Minerals strategy ambitions. It is intended that the MESH hydrogen production facility will produce graphite, a critical mineral essential for use in civil nuclear, defence and battery systems, as a by-product. MESH also complements the UK Government's ambitions to strengthen and diversify Barrow's economy. The development masterplan for Barrow is being spearheaded by Team Barrow, a UK Government initiative that involves BAE Systems, Westmorland & Furness Council and the Department of Housing, Communities and Local Government, as well as a range of local and national companies and organisations. Team Barrow has publicly welcomed the MESH project. Announcement • Apr 02
