The response characteristics of the overall process chain can be improved by an adequate storage capacity of biogas within the process and a harmonized and controlled operation of gas production, gas storage, and gas utilization.
The available gas storage (100%%) is utilized completely.
The consequent utilization of existing gas storage capacity can provide the biogas for flexible power generation [24] and represents the simplest approach and does not require many changes in design and operation.
It proves the feasibility for power management using gas storage, while reducing conventional capacity, with high utilization of technologies and increasing the contributions of renewable energies, at the same time that producing clean fuels for the hydrogen economy.
In such cases, besides the overcapacity required on the gas utilization side and sufficient gas storage, the flexibility of the plant can be improved by means of a feeding management and a correspondent control system for the biological process.
First, natural gas consumption from gas wells or gas storage facilities is reduced by utilizing gas produced from PtG units.
The Gas and Power segment engages in gas transit, gas storage, marketing, and trading.
This paper firstly begins with the utilization and development of hydrogen as energy, explains the significance of underground hydrogen storage and conventional storage methods, summarizes the underground gas storage experience of all countries, and concludes the general patterns of underground gas storage, for example, depleted reservoirs, aquifers, salt caverns and excavated caverns.
The gas unit also includes five natural gas storage reservoirs.
Methane can leak from gas storage tanks and pipes.
