Producing natural gas from wastewater and sunlight sounds like an idealized fuel production scenario, and that is just what a company called HyperSolar is claiming to be able to do.
Unlike many other companies making fuel using microorganisms, the HyperSolar process is designed to mimic photosynthesis with a nanomaterial. Hydrogen is produced at normal pressure, and then reacted with injected CO2 to produce methane.
Sunlight activates the nanomaterial particles and produces a charge which allows the particle to release hydrogen from the water. The process can even use untreated wastewater as a feedstock, and will produce clean water along with the natural gas.
This kind of natural gas would, of course, be preferable to fossil natural gas, since it would use already freed CO2 and leave the sequestered fossil carbon undisturbed. Moreover, it would serve as a source of natural gas without the need for controversial extraction methods like fracking.
Because the process takes place at normal pressure and temperature, it is less expensive than other systems that require large capital investments for the special equipment needed for their processes.
