Denmark has set ambitious goals for the decarbonization of its economy. The large and growing share of wind energy will lead to more frequent and prolonged periods of electricity supply, creating the need for bulk energy storage.
Denmark is aiming at procuring 50% of its total power consumption from domestic wind energy by 2020 and 80% by 2050. These ambitious renewables targets put the country at the global forefront of the energy transition. A large share of intermittent renewables will cause more frequent and prolonged periods in which electricity supply surpasses electricity demand. Since supply and demand in the power grid must be balanced at all time, any excess electricity needs to either be exported to neighboring countries or stored domestically for later use. Power-to-gas allows Denmark to use its state-of-the-art natural gas infrastructure to store wind energy in a practically unlimited manner.
Denmark is looking to also decarbonize other sectors of its economy. For instance, the Danish gas transmission grid operator Energinet.dk has made a public commitment to fully decarbonize the gas sector by 2050. P2G is a novel production route for renewable gas that can be used in transportation and heating applications.
In sum, Denmark’s unique natural resources and ambitious renewable targets create a great environment for the development and early deployment of the power-to-gas technology.
