Capabilities

The scientists and engineers of Greenway Energy (GWE) design, build and test hydrogen systems, from isotope separation to electrochemistry and materials.

Engineering services

  • Custom TCAP system design and support
  • Hydrogen and electrochemical system design: electrolyzers, fuel cells and hydrogen compression
  • Metal hydride systems
  • Techno-economic analysis and process modeling

Custom instrumentation

Custom Sieverts-type gas sorption (PCT) measurement units built to specification.

Laboratory

GWE's laboratory is in the Applied Research Center in Aiken, South Carolina, and is designed for hydrogen work. It supports air-sensitive synthesis and scale-up.

In-house analytical capabilities: scanning electron microscopy with energy-dispersive spectroscopy (SEM/EDS); hydrogen sorption capacity; pulse testing; packed bed flow testing; gas composition analysis; X-ray diffraction (XRD); ultraviolet-visible spectroscopy (UV-Vis).

Safety and quality

GWE's staff includes a Certified Occupational Safety Specialist (COSS) and a Certified Occupational Safety Manager (COSM). The lab also has first aid, CPR and AED instruction and written standard operating procedures.
