Over 1,000 metres below the ground – where natural gas was formed millions of years ago – renewable natural gas production will be investigated for the first time using a microbiological, environmentally friendly process. The aim of the RAG-initiated project is to carry out research on producing large quantities of renewable gas, using a carbon binding process, and storing it in naturally formed gas reservoirs, which will provide urgently needed flexibility for renewable energy sources.
This environmentally friendly process has three major advantages:
Natural gas storage facilities provide the essential service of seasonal compensation in the future energy system.
Thanks to Underground Sun Conversion-technology electricity can be converted into renewable gas and stored on large-scale on the same time.
The CO2 injected in the reservoir is part of a closed cycle and does not add to greenhouse gas emissions, compared to traditional production of natural gas.
In light of the Energy System Integration Strategy, this project turns RAG’s gas storage facilities into energy storage facilities, creating a link between and coupling gas and electricity sectors, so that they work together more closely.
