The Achilles' heel of all renewable energy sources has been and remains the absence of energy storage batteries of infinite volume. You cannot plan when the wind will spin the windmills to the maximum and how long it will blow, and therefore there is nowhere to put all the energy they generate. During periods of calm, accordingly, there is nowhere to take it. We need energy capacities with parameters that would make it possible to build cheaply as many storage facilities as required.
Researchers from Stanford University proposed to look at biological systems, specifically - bacteria of the species Methanococcus maripaludis. They consume hydrogen and carbon dioxide, and emit methane, which can be used as an energy carrier. The first is easily obtained by hydrolysis, passing electricity from the same wind turbines or solar panels through the water. And there is so much carbon dioxide in the atmosphere that any project for its absorption is automatically welcomed.
Mankind learned how to collect and store methane long ago - this is a matter of small investments and short operating time. It is also easy to extract energy from methane by burning it. Yes, in this case, the bound carbon dioxide will return to the atmosphere, but this will only restore its original concentration, and not add new volumes. And here is such an important fact - the capacities, power plants and pipelines that have already been built in many countries are suitable for methane processing; very little new infrastructure facilities will be required.
Livermore National Laboratory Lawrence (USA) and Southern California Gas have already joined the development of a real power plant based on this technology. The funding is handled directly by the US Department of Energy. This means that we will surely see the first bacterial farms and methane storage facilities in the next decade.
