100 kW AWE SYSTEM

Alkaline water electrolyser developed in collaboration with Rivan Industries.

A UK-based start-up building vertically integrated, modular synthetic fuel plants powered by off-grid solar to produce synthetic natural gas via. electrolysis, direct-air capture and methanation.

RIVAN INDUSTRIES

SSR Engineering supported Rivan Industries in their alkaline electrolyser stack development and co-built the in-house test platform, which evolved into the 100 kW pilot deployed on-site.

The objective was to design a 100 kW AWE system targeting £1/kg H2 and a balance-of-plant capable of pushing the stack to its limits.

WORK BY SSR ENGINEERING

RIVAN TECHNOLOGY OVERVIEW

Rivan designs, manufactures and deploys modular synthetic-fuel plants that pair an alkaline electrolyser (H2) and calcium-looping direct air capture unit (CO2), feeding their reactor engineered to GS(M)R gas-quality specifications to produce 99% pure methane, powered by low-cost solar electricity.

The resulting synthetic natural gas is a chemically identical, drop‑in replacement that can be injected into today’s UK gas grid and used by existing industrial equipment without modification. Containerised, field‑deployable modules shorten installation timelines and are designed around UK grid requirements for rapid interconnection and commissioning.

Rivan has successfully commissioned their pilot plant with a 100 kW electrolyser, raised £10 million in additional funding and is targeting 1 MW capacity next year, with total system capex under £150,000 and net efficiency above 30%
