SeeO2 is developing an efficient and a high performance reversible solid oxide cells (RSOFCs). Their technology, which involves the use of a high-performance catalyst material, allows the electrochemical conversion of water to hydrogen, carbon dioxide (CO2) to carbon monoxide (CO), and CO2 and water to produce syngas, a mixture of CO and H2.

The products (syngas, H2 and CO) can be used directly for various applications and can further be converted to substitute natural gas, methanol, ammonia, synthetic liquid fuels, etc. Their technology, when operated in the fuel cell mode, electrochemically converts H2, CO, syngas, and methane to power and heat for off-grid/remote customers, residential and commercial customers.

The company is still at an earlier stage of development for a fixed business model, but it will most likely license their technology on reversible solid oxide cells (RSOFCs) for the conversion of water to hydrogen and carbon dioxide to carbon monoxide or both together to syngas.

Their technology is based on Reversible Solid Oxide Fuel Cells (RSOFCs) - One device that can be operated in 2 modes.

• Solid oxide electrolysis cell (SOEC) mode: using power and heat to convert CO2 and/or water to produce fuels such as carbon monoxide (CO), syngas (H2 + CO), methane (CH4).
• Solid oxide fuel cell (SOFC) mode: it can operate with fuels such as hydrogen (H2) carbon monoxide (CO), syngas (H2 + CO), methane (CH4).

In most RSOFC configurations, a different electrocatalyst (electrode) is used at the fuel and oxygen electrodes, which adds manufacturing complexity and cost. Also, most of these catalysts are not very stable in high CO2 and/or water environments. The electrocatalyst developed by SeeO2, can be used in both the oxygen-rich environment of the oxygen electrode anode, producing oxygen, and at the CO2 / steam environment of the cathode, producing H2 and CO (syngas).

SeeO2 states these high-temperature SOECs have clear kinetic and thermodynamic advantages over existing lower-temperature approaches: reactions are faster, the options for alternative catalysts are broader and the catalysts are more stable.

SeeO2's platform technology provides 4 major solutions:

• CO2 to fuels and chemicals - a strategy for CO2 mitigation
• Power to fuels - means of energy storage especially for renewable energies (wind and solar)
• Fuels (CO, syngas, CH4) to power and heat - off-grid customers, stabilize grid, energy efficiency
• Pure oxygen generation - customers
