MESH positioned to accelerate the UK's energy transition
AIM listed EnergyPathways, an energy transition company, today announced progress on its MESH energy storage project in relation to hydrogen, long duration energy storage and low-carbon flexible power solutions.
EnergyPathways is distributing a specialised project briefing document outlining the conclusions from its hydrogen and clean energy pre-FEED activities and highlighting the critical role that hydrogen and compressed air storage technologies can play in reducing carbon emissions, enhancing energy security and becoming a cornerstone of the UK's transition to a sustainable net-zero economy.
Ideal Location for Integrated Energy Storage
MESH Key Project Highlights:
- Pre-FEED progress:Developing in line with schedule and remains on track for FID subject to award of the necessary licences applied for and requested
- 25-year project lifespan:Providing the UK with a secure and reliable supply of low carbon energy
- 20 TWh integrated energy storage capacity:Harnessing value from the UK's excess wind power and boosting energy security
- 400 MW hydrogen and compressed air Long Duration Energy Storage:Potentially Europe's largest LDES facility, providing multi-day power supply
- 700 MW low-carbon flexible power:Highly flexible future-proofed system for transition to carbon free hydrogen power
- Creating employment:Supporting a Just Transition for UK's offshore workforce
- Fully aligned with the Government's "Clean Power by 2030" mission and energy transition ambitions
The Company's hybrid compressed air storage solution (H-CAES), for which EnergyPathways has developed its own intellectual property, is a key part of a new, cutting-edge component of the MESH integrated energy storage project and the Company will provide more details on this aspect as the project progresses.
EnergyPathways has developed a pioneering and innovative approach to Long Duration Energy Storage (LDES) which it believes can make a major contribution to supporting the UK's renewable energy integration and providing security of power supply for the UK's businesses and households. The MESH LDES system will potentially be the largest of its kind in Europe.
By engaging with various influential stakeholders involved in the UK's energy transition, the Company will play its part in fostering collaboration and supporting future changes to policy frameworks to accelerate growth investment in the UKs energy transition.
Ben Clube, CEO of EnergyPathways plc said:
"We are pleased to have outlined our vision for MESH within the project briefing document that is being shared with the relevant stakeholders. The document's Project Highlights demonstrate that the proposed MESH project is an ambitious, bespoke and much needed project that has potential to make a material contribution to the UK, delivering on its net zero and energy security ambitions. Furthermore, the project has the potential to help kick start growth investment and contribute to supporting a "Just Transition" for the UK's highly skilled offshore work force and supply chain, resulting in positive socioeconomic impact beyond the clearly compelling environmental and commercial benefits that we have identified. I'm particularly proud to be able to demonstrate the depth of the Company's technical capabilities through the development of a pioneering approach to Long Duration Energy Storage, that we believe can make a material contribution to the UK delivering on its net zero energy transition ambitions and "Clean Power by 2030" target. We look forward to providing further updates on MESH as we progress through the FEED stages and engage with key stakeholders."
MESH (Marram Energy Storage Hub)
The new UK Government is dedicated to doubling onshore wind and quadrupling offshore wind by 2030, as a central part of its plan to fully decarbonise electricity. In that time, UK wind capacity will increase from ~30 GW to ~90 GW.
With major constraints in the UK transmission grid and current wind capacity already at ~80% of peak winter demand, we fear that much of this taxpayer subsidised investment in wind expansion will be wasted. Wind curtailments already cost UK taxpayers ~£1bn p.a. and look set to rise steeply to ~£5+bn by 2030.
Gas, accounting for ~32% of the UK’s energy mix, will remain a critical transition fuel until green hydrogen storage can be deployed at scale to harness excess wind. Until then, gas is needed to fill the demand gaps arising from intermittent wind power and is vital for supplying heat to UK homes and industries.
The UK has some of the lowest levels of gas storage of the world’s major economies. With ~40% of UK energy supply already imported, and gas imports set to rise to 80% of gas demand by 2030, gas storage will be essential to secure reliable energy supply and reduce the impact of global prices on household bills.
Ideal Location for Integrated Energy Storage
EnergyPathways is developing integrated energy storage that can provide the UK with secure flexible gas supply and leverage the growing value loss from the UK’s excess wind power by utilising green hydrogen storage solutions.
EnergyPathway’s MESH project (Marram Energy Storage Hub), located 11 miles from the Lancashire coast is an ideal location for energy storage development.
MESH is using high-quality geo-storage reservoirs within the region’s gas fields. These reservoirs have high injection and withdrawal rate attributes – ideal for flexible and reliable energy supply to back up intermittent wind, as well as meet volatile demand.
MESH is surrounded by 7-8GW of planned and existing offshore wind power that will be used to provide decarbonised energy to power the facility and store excess wind energy as green hydrogen.
Being close to existing late life gas pipelines, gas processing and offshore transmission lines, MESH can use these to readily connect new energy supply to the UK market, with the high population and industrial demand centres of North-West England nearby.
MESH is also well positioned to integrate with the nearby CCS sequestration reservoirs and the UK’s leading hydrogen hub - HyNet North-West - to bolster decarbonised energy supply for industrial clusters and peaking gas power.
MESH - Major Gas & Green Hydrogen Storage Facility
MESH energy storage infrastructure will provide a secure and reliable supply of natural gas and green hydrogen for over 25 years. It is designed as an integrated zero GHG emission storage facility, fully electrified and powered by the region’s nearby renewable energy.
MESH’s storage capacity of ~14 TWh (~50 bn cubic feet of gas) will be of equivalent size to Centrica’s Rough facility, currently UK’s largest, and it will increase UK’s gas storage capacity by ~50%. It will be able to store an equivalent volume of energy to heat 2.5 million UK homes over winter.
EnergyPathways’ development will use the UK’s oil and gas, and renewable work force and businesses. It comprises a gas storage project of 4 wells with pilot green hydrogen production that is positioned to harness the UK’s excess wind power with scaled up. Gas storage will be developed across two phases with initial formation gas production followed by full gas storage operations.
High Yield Infrastructure Returns
The MESH project schedule is to reach development plan approval and FID in late 2025, with operational revenues starting late 2027. Project development is subject to the award of a UK regulated storage licence.
The investment will benefit from early high cash flows from formation gas production that will finance second phase development.
Positioned for Growth
EnergyPathways has formed a consortium of top tier energy companies to develop the MESH comprising; one of the world’s largest developers of wind power, one of world’s largest integrated oil and gas companies, a FTSE 250 global leading engineering consultancy and global market leader in industrial automation and industrial software.
EnergyPathways has identified 2 further high-quality geo-storage reservoirs, Knox and Lowry, and a geo-salt sequence for energy storage development. These are located nearby to MESH and can be readily integrated to treble MESH’s energy storage capacity. EnergyPathways has requested storage and production licences to be awarded by the regulator for these geological resources.
