In order to store extra electricity from renewable energy sources like solar and wind power, power-to-gas (P2G) energy storage transforms it through the electrolysis process into a chemical energy carrier, such as hydrogen or methane gas. Hydrogen is caught and kept as a gas after being divided into its component parts, hydrogen and oxygen, utilizing energy in the process.
The hydrogen that has been stored can be utilized in many different ways, such as as car fuel or as a raw material for the manufacture of chemicals or other energy-related goods.
Alternately, carbon dioxide (CO2) and hydrogen can be combined to create synthetic methane gas, which can be injected into the natural gas distribution system or used as a fuel for electricity production.
Compared to alternative methods of energy storage like batteries or pumped hydro storage, P2G has a number of benefits. The ability to store energy for a long period of time, which is essential for the grid’s integration of intermittent renewable energy sources, is one of its key benefits.
P2G may be used at several sizes, from small-scale decentralized systems to large-scale centralized facilities, making it a flexible and scalable energy storage option. Though P2G has some advantages over other types of energy storage, it also has some drawbacks, such as low conversion efficiencies and high costs.
Though P2G has some advantages over other types of energy storage, it also has some drawbacks, such as low conversion efficiencies and high costs.
Despite these obstacles, P2G is regarded as a promising technology for the shift to a low-carbon energy system because it can help decarbonize a number of industries, including power generation, transportation, and other sectors.
The first phase of Electrochaea’s two-step biomethanation process is the electrolysis of water to produce hydrogen.
The biocatalyst, a methanogenic archaea, is housed in a reactor that is fed with renewable hydrogen and carbon dioxide. Renewable methane is the end product that comes out of the reactorThe French business McPhy Energy specializes in hydrogen-based energy storage and delivery systems. “McStore,” a power-to-gas energy storage technology, is one of their key offerings.
Through electrolysis, surplus electricity is converted in this system into hydrogen, which is then stored and used for a variety of purposes, including gas grids and fuel cells.
The scalable, adaptable, and modular design features of McStore make it simple to integrate into current energy systems. It is a dependable and affordable alternative for energy storage since it is made to have a long lifespan and require less maintenance.
