EnergyPathways, an England-based energy transition-focused player, has made significant progress towards the final investment decision (FID) in 2025 for its Marram Energy Storage Hub (MESH) project in the East Irish Sea. The project aims to provide a secure and dependable supply of natural gas and green hydrogen to the UK market for over 20 years, with an estimated gas storage capacity of up to 50 billion cubic feet. The project, expected to be operational at the end of 2027, is designed to be fully decarbonized and electrified, powered by renewable wind farms in the UK Irish Sea region. EnergyPathways has secured the license operatorship approval from the North Sea Transition Authority (NSTA) and has engaged PDi for engineering study support for the project's development. The company also appointed Wood as the project lead engineering partner to progress through various phases. The project's strategic location near major grid constraint boundaries and existing offshore wind farms with substantial capacity makes it an ideal site for energy storage and backup gas power generation. The company sees the MESH project as a game-changer, with the potential to store an estimated 7 TWh of energy and become the UK's largest natural gas and hydrogen energy storage facility. The focus on collaboration with industry experts and the innovative approach towards addressing energy security and global energy price volatility showcases EnergyPathways' commitment to developing a significant energy infrastructure project for the UK market.
