FREMONT, CA: A paradigm shift in focus from competition to decarbonization has initiated a spark, which has effected a change in other sectors as well. The challenge is the fulfillment of greater necessity for energy flexibility with regard to storage as a primary provider.
With this in mind, European gas storage operators are equipping themselves for the future and have taken positions as the driving forces for storage systems in case of surplus generation putting an end to the risk of curtailment. Many operators across Europe now have run demonstration projects from MWh scales to various sources like power to gas, power to heat, and storage of pure hydrogen.
The integral part of the natural gas systems are gas storage facilities, which were constructed along with transmission and distribution systems, and for years it has been a primary feature of gas systems. The gas storage capacity in the EU is around 1000 TWh; the storage systems have enabled storing of gas for a long time to a couple of hours.
The existing storage capacity has the potential to store various green and decarbonised gases in the future. The storage operators believe that bio-methane and synthetic methane are two among various gases that can be stored. Pure hydrogen would work effectively with cavern storages as well. In many parts of Europe, the agenda at present is dominated by renewable energy sources and the zero-carbon economy as gas storage can provide energy storage in the long run, thus balancing the battery through technologies such as power to gas. The policy-makers are dwelling on the need to prioritize the removal of lignite from the energy mix. The gas storage systems help in cost-cutting as well. They curb the cost of transmission, which provides insurance against technical downtime. Gas storage can be the missing puzzle piece in the future world of decarbonized energy if implemented with best practices by changing the fundamentals on the supply side; it can be the driving force for a transition toward the greener energy.
