Power to gas (often abbreviated P2G) is a technology that converts power to a gas. Fisheye Hemi Serial Macromedia more. [1] There are currently three methods in use; all use electricity to into and by means of. In the first method, the resulting hydrogen is injected into the natural gas grid or is used in transport or industry. [2] The second method is to combine the hydrogen with and convert the two gases to (see ) using a methanation reaction such as the, or biological methanation resulting in an extra energy conversion loss of 8%. The methane may then be fed into the natural gas grid. The third method uses the output gas of a or a plant, after the is mixed with the produced hydrogen from the electrolyzer, to upgrade the quality of the biogas.

Impurities, such as,,, and, must be removed from the biogas if the gas is used for pipeline storage to prevent damage. Contents • Storage function 1 • Efficiency 1.1 • Electrolysis technology 1.

The excess power or off-peak power generated by wind generators or solar arrays may then be used at a later time for load balancing in the energy grid. Before switching to, the German gas networks were operated using, which for 50-60% consisted of hydrogen.

The storage capacity of the German natural gas network is more than 200,000 GWh which is enough for several months of energy requirement. By comparison, the capacity of all German pumped storage power plants amounts to only about 40 GWh. The storage requirement in Germany is estimated at 16GW in 2023, 80GW in 2033 and 130GW in 2050. [4] The transport of energy through a gas network is done with much less loss (. In 2013 the round-trip efficiency of power-to-gas-storage was well below 50%, with the hydrogen path being able to reach an maximum efficiency of ~ 43% and methan of ~ 39% by using combined-cycle powerplants. If plants are used that produce both electricity and heat, efficiency can be above 60%, but is still less than pumped hydro or battery storage. [8] However, there are is potential to increase efficieny of power-to-gas storage.

In 2015 a study published in found that by using and recycling waste heat in the storage process a round-trip efficiency electricity to electricity of more than 70% can be reached at low cost. Electrolysis technology • Advantages and disadvantages of the predominantly considered electrolysis technologies. [11] Alkaline Electrolysis Advantage Disadvantage Commercial technology (high technology readiness level) Limited cost reduction and efficiency improvement potential Low investment electrolyser High maintenance intensity Large stack size Modest reactivity, ramp rates and flexibility (minimal load 20%) Extremely low hydrogen impurity (0,001%) Stacks.

In April 2014 the co-financed and from the coordinated [32] HELMETH [33] (Integrated High-Temperature ELectrolysis and METHanation for Effective Power to Gas Conversion) research project started. [34] The objective of the project is the proof of concept of a highly efficient Power-to-Gas technology by thermally integrating high temperature electrolysis ( technology) with CO 2-methanation. Through the thermal integration of exothermal methanation and steam generation for the high temperature steam electrolysis a conversion efficiency >85% is expected ( of produced methane per used electrical energy). The process consists of a pressurized high-temperature steam and a pressurized CO 2-methanation module which are planned to be coupled in 2016. A methane output of approximately 30 kW (higher heating value) is targeted. The first industry-scale Power-to-Methane plant was realized by ETOGAS for Audi AG in Werlte, Germany. The plant with 6 MW electrical input power is using CO 2 from a waste-biogas plant and intermittent renewable power to produce synthetic natural gas (SNG) which is directly fed into the local gas grid (which is operated by EWE).
