GEN01X

Executive Overview

GEN01X is a 50 MW / 300 MWh liquid air energy storage (LAES) facility under construction at the Trafford Low Carbon Energy Park in Carrington, Greater Manchester, developed by Highview Power. Groundbreaking took place in November 2025. The project is structured in two phases: Phase 1 is a grid stabilisation component — a synchronous condenser ‘stability island’ providing inertia, reactive power, and short-circuit capacity to the local grid — targeted to be operational from 2026. Phase 2 delivers the 300 MWh / 50 MW LAES storage capability, with six hours of continuous discharge, and represents the primary storage asset. The project is financed by a £300 million package from the UK Infrastructure Bank (£165 million in debt and equity), Centrica, Rio Tinto, Goldman Sachs, KIRKBI, and Mosaic Capital. GEN01X is the first project in Highview's planned UK programme, and the company projects the full UK programme could power 7.6 million homes and contribute £2.7 billion to the economy by 2035.

How It Works & Differentiation

Highview's CRYOBattery system stores electricity by using surplus power to cool air to approximately -196°C, liquefying it and storing the liquid air in low-pressure insulated tanks. When electricity is needed, the liquid air is warmed, expands, and drives turbines to regenerate power. The stability island (Phase 1) provides synchronous inertia, reactive power (100 MVAr), and short-circuit capacity — grid services that battery storage cannot supply — independently of the LAES storage system. The full system operates without performance degradation for 40–50 years and uses no hazardous materials, rare metals, or water in the storage cycle. The Hatsukaichi LAES plant in Japan (5 MW / 20 MWh, operational December 2025) provides the first real-world operational reference for Highview's technology platform.

Commercialization & Traction

The UK Infrastructure Bank investment of £165 million is the most significant single institutional commitment to LAES in the UK to date. Highview's two larger projects — Hunterston (North Ayrshire, 300 MW / 3.2 GWh) and Killingholme (Lincolnshire, 3.2 GWh) — have passed Ofgem's eligibility screening for the cap-and-floor long-duration storage support scheme, with final awards expected in summer 2026. The GEN01X project is expected to support up to 700 jobs during construction and demonstrates the technology at commercial scale ahead of the larger Millennium Series deployments.

Scalability & Strategic Context

GEN01X is the commercial-scale debut of the CRYOBattery platform in the UK market and will be the world's first full-size grid-connected LAES storage plant. The UK National Grid forecasts up to 29 GW of storage needed by 2030 and 51 GW by 2050, against approximately 5 GW currently installed. Ofgem's cap-and-floor regime — modelled on the mechanism that unlocked over 8 GW of interconnector capacity — is expected to provide the revenue certainty needed to finance the larger Millennium Series projects. The technology's 50-year operating life and ability to be sited at brownfield locations without water or topographic constraints give it deployment advantages that neither pumped hydro nor compressed air energy storage can match across UK geography.
