TCAP ISOTOPE SEPARATION · WATER DETRITIATION · ALANE

Hydrogen technology for the fusion era.

Greenway Energy (GWE) designs and builds TCAP isotope separation systems, develops electrochemical water detritiation, and produces alane, a solid hydrogen fuel for fuel cells.

Live simulation: thermal cycling separates hydrogen isotopes.

Three ways we work with hydrogen

GWE TCAP Systems

Custom palladium-based systems that separate protium, deuterium and tritium, built on technology in production at the Savannah River Site since 1994.

GWE Water Detritiation

A patent-pending electrochemical approach to recovering tritium from water.

GWE Alane

Aluminum hydride: a solid that stores hydrogen for fuel cells in long-running, compact power systems.

Built for the fusion fuel cycle

A fusion power plant must continuously recover, purify and recycle its tritium fuel. GWE's technologies address two of the hardest steps: hydrogen isotope separation and water detritiation.
