Why it's on ClimateTicker

Highview Power's core product — liquid air energy storage (LAES) — is a genuine, physics-grounded enabler of renewable energy integration that directly displaces the need for fossil-fuel peakers and reduces curtailment of wind and solar. The technology thesis is credible and well-backed by serious institutional capital including the UK National Wealth Fund and Centrica. However, as a pre-revenue, pre-commercial-scale company still in construction phase, climate impact is prospective rather than proven, and formal sustainability governance (SBTi, CDP, ESG reporting) is essentially absent from public record.

enablerHighview Power develops, owns, and operates long-duration energy storage facilities using its proprietary LAES/CRYOBattery technology, generating revenue through grid services (capacity, inertia, black start, voltage support) and energy arbitrage under UK government cap-and-floor support mechanisms and bilateral offtake arrangements.

Controversy & Greenwashing Watch

lowNo public ESG or sustainability disclosure

Despite marketing itself as a net-zero enabling technology company and receiving public institutional finance, Highview Power publishes no sustainability report, GHG inventory, SBTi commitment, or CDP response — creating a transparency gap between its green positioning and verifiable corporate conduct.source ↗

lowCommercial operation delay — Carrington

The Carrington facility was originally announced as operational in 'early 2026' at the time of the June 2024 fundraise, but as of November 2025 groundbreaking the LAES system completion date had slipped to 2027, with only the stability island targeting August 2026 — a ~12-18 month schedule slip that increases execution risk.source ↗
