As electrical energy is not easily stored, it is often easier to disconnect IRR from the power grid rather than storing electrical surplus. This means energy is lost. A solution for avoiding this energy losses is provided by Power To Gas, or the injection of green hydrogen into the natural gas network. In the case of wind-power production, we speak for example of "making the wind blow into the natural gas network". The Power to Gas concept is to use the existing natural gas distribution network to store electricity losses and move it to another point of use. Applications Energy losses produced by IRR is converted into green hydrogen using water electrolysis. This green hydrogen is then used as an energy vector, which can have several applications: It can be used via gas power stations to generate electricity. Thus the electricity network and the gas network are connected in both directions. It can be injected directly into the natural gas network, within a limit of 20 %, to be used by natural-gas users in the usual manner. It can be combined with CO2 to give methane (CH4) and water (principle of methanation). This synthetic renewable methane can then be injected into the natural gas network in a simple and unlimited way. It can be used in mobility for all vehicles currently using CNG (Compressed Natural Gas), which can then be driven using Hythane© (mixture of 80 % CH4 and 20 % H2). The main advantages Optimization of green electricity losses The use of already existing networks reduces the investment required for this new energy source The use of green hydrogen in the natural-gas stream reduces the carbon footprint of CH4 Methane, whether natural, synthesized through methanation, or mixed with hydrogen, can be used for virtually all energy applications: heating, hot water, cooking, electricity generation, mobility, etc. McPhy is positioning itself in the Gas To Power market, providing electrolyzers to transform green hydrogen and electricity losses by providing hydrogen storage solutions to optimize conditions for injection into the natural gas network. The first major application for McPhy in the Power To Gas concept is participation in GRHYD, in collaboration with GDF Suez in France. © 2015 McPhy Energy S.A.
