Optimal Day-Ahead Scheduling of Power-to-Gas Energy Storage
Power-to-gas (PtG) energy storage converts electricity to hydrogen or synthetic natural gas. The gas produced is stored and converted back to electricity at a later time; or it is directly used to supply a gas load and/or sell in the gas market. In the first case, due to double energy conversion in a relatively less efficient process, a large portion of the energy is wasted.

6 FAQs about [Ptg energy storage]
What is power-to-gas energy storage?
Abstract: Power-to-gas (PtG) energy storage converts electricity to hydrogen or synthetic natural gas. The gas produced is stored and converted back to electricity at a later time; or it is directly used to supply a gas load and/or sell in the gas market.
Is high temperature PTG a viable long term storage technology?
However, an evaluation of plant operational modes is required to completely qualify high temperature SOEC and methanation based PtG systems (hereafter referred to as High Temperature PtG systems) as a genuine long term storage technology. PtG based storage should not only be technically feasible but also economically viable.
Can subsurface energy storage be used in PTG systems?
If this technology can be successfully used in the subsurface energy storage of PtG systems, a large amount of money that was used to buy expensive methane to use as a cushion in the case of aquifer and cavern storage reservoirs will be saved.
Is PTG a good option for energy storage?
PtG with subsurface energy storage is seen as an attractive way to reduce emissions and adjust the energy structure by increasing the share of renewable energy and its utilization efficiency in the future. Although this technology has many laudable points, there are still many problems that need to be solved for practical application.
Why is PTG technology important in China?
Forced by the environmental pressure and energy shortage, developing the PtG and subsurface energy storage technology in China is of great necessary. The basic process of the PtG technology mainly divided into three parts, namely electrolysis & methanation, energy storage and energy discharge.
Why is PTG so expensive?
According to Kühn , electricity production based on PtG is expensive compared to traditional fossil energy power plants, but is still competitive in relation to other energy storage technologies such as PHS and CAES. Hereby, operational time and the price of electricity are the two main factors that affect the operation costs of PtG .
