6 FAQs about [China gas storage and energy storage]
How much natural gas will be stored in China?
In 2018, the Guidance on Energy Work issued by the China National Energy Administration clearly pointed out that 3.5 × 10 10 m 3 of effective working gas will be placed in underground gas storage, and a natural gas reserve system will be established by 2030 .
Why is China expanding natural gas storage capabilities?
China is expanding natural gas storage capabilities to ensure a reliable and sustainable energy future as part of its "carbon peaking and neutrality" strategy. It plans to establish six major gas storage centers across the country, with a total of 50 gas storage facilities and an estimated working gas volume exceeding 100 billion cubic meters.
How many GW of energy storage systems are there in China?
The year 2023 saw 21.5 gigawatts (GW) of energy storage systems brought into operation in China, exceeding the previous year by 194%, according to the China Energy Storage Alliance (CNESA).
Which natural gas storage facilities are used in China?
At present, China’s large-scale natural gas storage facilities mainly include depleted reservoirs, salt caverns, and LNG storage tanks. According to international practice, it is only once the storage of working gas reaches about 15% of annual consumption that a safe supply of natural gas can be ensured .
Which energy storage systems are being commercialised in China?
In addition to lithium-ion batteries, China is commercialising other types of energy storage systems. This includes the compressed air energy storage (CAES) technology, which consists of two stages.
Why is energy storage important in China?
Energy storage is developing rapidly with the advantages of high flexibility, fast response time, and ample room for technological progress. China encourages energy storage to provide auxiliary power services to meet the needs of new power systems.
