Power-to-gas: The key enabler for a CO2-neutral energy system

In this in-depth analysis from Dr Frank Graf at the DVGW Research Center at Engler-Bunte-Institute of Karlsruhe Institute of Technology (KIT), we find out that the project STORE&GO demonstrates how green methane provides a keystone for the cross-sector energy transition. We also learn that Power-to-Gas (PtG) is defined as electricity from renewable sources used to split water into hydrogen and oxygen via electrolysis

On a policy note, our attention is drawn to the ambitious targets set by the European Union to reduce greenhouse gas emissions by at least 40% by 2030 compared to 1990 and 80–95% by 2050. Dr Frank Graf argues that for the EU to meet the assigned climate targets, energy production must come mainly from renewable sources. The author also explains that the potential of power-to-gas (PtG) applications in the European energy grid is an important step in the energy transition because it makes the most efficient use of renewable energies.

We also find out about three pilot plants with different innovative power-to-gas technologies, funded under Horizon 2020. For example, one of these pilots is in Falkenhagen, Germany and demonstrates the operation of an integrated innovative PtG plant to produce synthetic methane (SNG). Another demo site is located at Zuchwil/Solothurn, Switzerland, where a special feature of this pilot project is that a biological methanation process is used for the conversion of the produced hydrogen to SNG.

As a special piece of bonus content, I hope you enjoy reading an interview with Maroš Šefčovič, Vice-President, Energy Union at European Commission. He speaks to Open Access Government about establishing a European Energy Union and the importance of all Europeans having access to secure, affordable and climate-friendly energy.

I trust that you find the many insights in this e-book interesting and useful.
