EnergyPathways Secures £15 million to Advance LDES
Estimated reading time: 5 minutes · Last updated:
EnergyPathways reported a £15 million financing package and regulatory progress in the first half of 2026 as it pushes its MESH platform toward development. The financing comprises a £5 million convertible loan and a £10 million at-the-market equity facility to support multiple energy transition projects. The company accepted Gas Storage Licence GSL009 from the North Sea Transition Authority, for storage of both natural gas and hydrogen, and started Front End Engineering & Design for its long-duration energy storage project. EnergyPathways also signed an agreement with Associated British Ports to evaluate the Port of Barrow for onshore facilities and said it is engaging with the UK Government and stakeholders ahead of final investment decisions.
Key takeaways
- Financing: EnergyPathways closed a £15 million package made up of a £5 million convertible loan and a £10 million at-the-market equity facility.
- Regulatory milestone: The company formally accepted Gas Storage Licence GSL009 from the North Sea Transition Authority for natural gas and hydrogen storage.
- Project engineering: EnergyPathways started Front End Engineering & Design for its long-duration energy storage (LDES) project.
- Financial result and leadership: The company reported a first-half loss of £1.95 million versus a loss of approximately £607,000 in the first half of 2025 and appointed Alison Flower and Martyn Millwood Hargrave to senior roles.

What the £15 million package covers and the LDES work under way
EnergyPathways said the financing package totals £15 million and is split between a £5 million convertible loan and a £10 million at-the-market equity facility. The company described the capital as additional funding while it advances multiple projects toward final investment decisions. In the same reporting period EnergyPathways started Front End Engineering & Design, commonly abbreviated FEED, for its long-duration energy storage project, or LDES. FEED is the engineering phase that develops scope, costs and schedules ahead of a final investment decision and permits, and EnergyPathways presented its FEED start as a step toward project definition.
The project is being developed as part of MESH, an integrated system the company says will combine long-duration storage, strategic gas and hydrogen storage, and hydrogen-related industries. The combination of the convertible loan and the equity facility is intended to provide working capital and market liquidity as the LDES FEED proceeds and as the company pursues regulatory and commercial approvals required for construction and operation.
Regulatory and technology milestones: GSL009, patent filing and partners
During the period EnergyPathways formally accepted Gas Storage Licence GSL009 from the North Sea Transition Authority, a licence the company says covers storage of both natural gas and hydrogen. That licence underpins the strategic gas and hydrogen storage element of the MESH platform and is the named regulatory milestone the firm reported.
Post-period developments expanded the company's engineering and technology capabilities. EnergyPathways appointed Jacobs as its engineering and regulatory partner and submitted a patent application related to its compressed air energy storage system. The company also signed a collaboration agreement with Hycamite TCD Technologies to evaluate technology for producing high-grade graphite and low-carbon hydrogen, and reached an agreement with Associated British Ports to evaluate the Port of Barrow as a location for onshore facilities that would support MESH.
Financial position, governance changes and the path to investment decisions
EnergyPathways reported a first-half loss of £1.95 million, compared with a loss of approximately £607,000 in the corresponding period of 2025. The wider cash and funding plan the company will use to reach final investment decisions was not detailed in the items it reported for the first half.
Leadership changes during the period included the appointment of Alison Flower as a Non-Executive Director and Martyn Millwood Hargrave as Chief Scientific Officer. EnergyPathways said it is engaging with the UK Government and other stakeholders as it works to move LDES, gas and hydrogen storage, and hydrogen-related projects toward final investment decisions. Those engagements, together with FEED, the GSL009 licence and the new partnerships, are the operational moves EnergyPathways highlighted as advancing project readiness ahead of commercial commitments.
| Item | Detail |
|---|---|
| Total financing | £15 million |
| Convertible loan | £5 million |
| Equity facility | £10 million at-the-market |
| Gas storage licence | GSL009 (natural gas and hydrogen) |
| Engineering partner | Jacobs |
| Technology collaborator | Hycamite TCD Technologies |
Case for and against EnergyPathways reaching FID
The case for
- The £15 million financing package and the start of FEED give EnergyPathways defined capital and engineering scope to advance LDES and storage concepts toward final investment decisions.
- Regulatory progress with Gas Storage Licence GSL009 and new technical partnerships, including Jacobs and Hycamite TCD Technologies, expand the company's practical and commercial options for MESH deployment.
The case against
- Reported losses — a first-half loss of £1.95 million versus about £607,000 a year earlier — increase near-term funding needs and may require further rounds before construction funding can be secured.
- Key outcomes remain pending: FEED conclusions, patent prosecution results, the Port of Barrow evaluation and government or permitting approvals are all prerequisites to a final investment decision.
What to be careful about
- FEED may identify higher capital or schedule requirements than assumed, delaying final investment decisions.
- The patent application for the compressed air energy storage system may not be granted or may not provide commercial protection.
- The Port of Barrow evaluation with Associated British Ports may rule out the site or require additional works that increase costs.
- Continued operational losses could force further fundraising on terms that dilute existing shareholders or alter project economics.
The bottom line
EnergyPathways has bundled regulatory, engineering and financing moves into a single development push for its MESH platform and LDES project: a £15 million financing package, acceptance of Gas Storage Licence GSL009, FEED work on LDES, and named partnerships with Jacobs and Hycamite TCD Technologies. Those steps reduce near-term uncertainty by creating defined workstreams and technical links, but the company’s larger financing and permitting hurdles remain. The immediate momentum improves project readiness; FEED outputs, patent outcomes and site evaluations will determine whether the firm can reach final investment decisions and move into construction.
What to watch
- Watch for EnergyPathways' final investment decision on its LDES project; no date has been set.
- Watch for the published outcome of the Port of Barrow evaluation with Associated British Ports; no date has been set.
- Watch for FEED conclusions for the LDES work that will set scope and cost estimates; no date has been set.
