25cm2 AWE TRANSPARENT CELL

Alkaline water electrolyser developed in collaboration with Rivan Industries, with a transparent viewing window.

RIVAN INDUSTRIES

SSR Engineering supported Rivan Industries' alkaline electrolyser development by designing a lab-scale 25cm2 test cell with a transparent viewing window for real-time visualisation.

Built for rapid experimentation rather than durability, the cell let the team observe bubble formation while varying current density, electrolyte pump speed, and comparing commercially available meshes to inform material and flow choices. The quick‑turn insights de‑risked subsequent robust stack designs by exposing gas‑evolution behaviour early in the development cycle.

You may notice a difference between the bubble formations between the electrodes. An electrolyser's volumetric production ratio of H2 to O2 is 2:1, although the H2 bubbles are smaller and their bubble detachment diameters differ.

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 succesfully 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%
