While Planetoid Mines has engineered a solid oxide electrolysis cells to be used both on the Earth and Moon, future missions to Mars and applications on Earth will use our one-step conversion process of carbon dioxide and water into liquid hydrocarbon fuel using light, heat, and pressure.
SOEC electrolysers can operate at high temperatures, therefore light hydrocarbon fuels such as methane, kerosene, propane, and butane can be internally reformed within the anode. SOFCs can also be fueled by externally reforming heavier hydrocarbons, such as gasoline, diesel, jet fuel (JP-8) or biofuels. Such reformates are mixtures of hydrogen, carbon monoxide, carbon dioxide, steam and methane, formed by reacting the hydrocarbon fuels with oxygen or steam in a device upstream of the SOFC anode.
On Earth, our solar photothermochemical alkane reverse combustion, or the "one-step" conversion process that can turn carbon dioxide and water into oxygen and liquid hydrocarbons using a photothermochemical flow reactor operating at around 180° C to 200° C and at pressures up to six atmospheres.
The hybrid photochemical and thermochemical reaction uses a titanium dioxide (TiO2) photocatalyst, although expensive on Earth, TiO2 will be returned from the Lunar Soil for catalyst and metal hydride batteries.
Our photochemical reaction generates high-energy intermediates and heat to drive a thermochemical carbon-chain-forming reaction, thus producing the following hydrocarbons in a single-step process:
