Product Overview

Overview
  • Solid Oxide Cells (SOFC) Sunfire manufactures solid oxide cells for the incorporation in fuel cells and steam electrolyzers. The company offers two fuel cell systems: a 400 W fuel cell-only and 1.2 kW solar-plus-fuel cell mobile unit for remote and off-grid sites and a 750 W CHP system for residential sites. Both systems are fueled by propane or natural gas.

  • Hydrogen: Sunfire Hylink electrolyzers produce renewable hydrogen - targeted for industries as well as the energy and mobility sectors.

  • Syngas: Sunfire SynLink electrolysers produce renewable syngas - the feed gas for different hydrocarbon products such as e-Fuel and chemicals.

  • E-Fuel: Synthetic transport fuels ("e-Fuel") produced from renewable syngas substitute fossil fuels such as gasoline, diesel, and jet fuel.

Electrolysis Solutions

  • Alkaline Electrolyzers
  • SOEC Electrolyzers
Business Model

Per system, from private home use to utility scale application.

Technology Innovations
  • Solid oxide cell stack consists of low cost ceramics and steel and can be used for both hydrogen and electricity production.
  • Sunfire's pressurized Alkaline electrolyzer can be used for applications with or without limited steam availability and has a system lifetime of at least 90,000 operating hours.
  • All systems utilize modern modular system design.
Applications
  • Waste heat hydrogen production: industrial waste steam output conversion to hydrogen fuel, which can then be used as electricity supply and reducing energy costs.

  • Remote power: small mobile unit for small remote power needs, targeted to the oil and gas industry.

E-FUEL: Sunfire's SynLink SOEC technology allows for cost-effective production of various e-Fuel blends, suitable for fuel suppliers, airlines, and logistics companies.

Industrial Use: Sunfire's SynLink electrolyzer aids the chemical industry by producing syngas from CO2 sources, which can then be used as a primary feedstock in various chemical processes to manufacture products such as fertilizers, agrochemicals, pharmaceuticals, and others.
