Roadmap for Power to Gas in Germany
The dena Power to Gas Strategy Platform has published a Roadmap Power to Gas as a pathway towards market integration till the year 2020/2025.
The Roadmap identifies the relevant activities to be done in the future. The Power to Gas Roadmap is under permanent revision. (Link to the german version).
Power to Gas: System Solution
Power to Gas is a particularly promising system solution. The idea behind Power to Gas is to convert renewable electricity to hydrogen or methane, store it in the gas infrastructure and then use it in a variety of consumption areas. Hydrogen and methane from renewable electricity can be used equally in mobility, industrial, heat supply and electricity generation applications. That makes Power to Gas a multi-system solution which supports the integration of renewable energy into the energy system and also contributes to reaching the ambitious goals of reducing emissions of greenhouse gases and the sustainability goals in all areas of consumption.
As an electricity storage method, Power to Gas can also contribute to compensating the increasing fluctuations in electricity generation from wind and solar energy and facilitate long-term use of electricity which could not be integrated directly into the electricity grid at times of particularly high renewable generation.
Benefits of Power to Gas
The main benefits of Power to Gas technology for the entire energy system are:
- Transfer of electricity into other demand sectors – electricity, heat, mobility and industrial use – to fulfill ambitious political targets (e.g. greenhouse gas reductions)
- Power to Gas provides flexibility for the electricity system and thus supports the integration of renewable energy
- Power to Gas uses existing infrastructure, e.g. natural gas network, natural gas storage facilities and power generation facilities
- Power to Gas technology will be a key player for energy storage – especially long term storage – in a future energy system
- Power to Gas technology is mature and ready for use
Today there are already 14 pilot and demonstration projects in Germany in operation and more than 17 facilities are under construction (project overview in german). Several international projects are underway as well.
