Can LNG be stored long-term?

Though storage of LNG is more energy demanding than storage of gaseous NG, it can be offset by the lower energy demand for long distance transportation of LNG as could be seen Fig. 8. The boil-off makes LNG generally unsuitable for long-term (more than a few weeks) energy storage.

What is natural gas consumption of LNG process?

Natural gas consumption of LNG process. Regasification of LNG is the process with the highest potential for energy recovery. Though the recovered energy is in the form of heat or cold, it can be used in power generation and thus increase the efficiency of power production.

Why is LNG important for transport & storage?

Because LNG has a large energy volume density, it is very advantageous for transport and storage. Transport of LNG over long distances is done almost exclusively in ships. The loading and unloading of LNG in port terminals is a periodic process that requires enough capacity of the LNG port storage tanks.

Can LNG be used as an energy storage medium?

The boil-off makes LNG generally unsuitable for long-term (more than a few weeks) energy storage. Nonetheless, in situations where the consumption of NG is about the same as the amount of boil-off gas, LNG could be used as an energy storage medium.

Do LNG storage tanks have thermal insulation?

LNG storage tanks have a simple design with a high-quality thermal insulation that wraps the external shell of the tank. Thermal insulation reduces heat gains from the surrounding environment but cannot fully prevent it.

How efficient is LNG storage?

A case with the following parameters was considered: 8 h charging at 60 MW, 8 h reserve, and 8 h generation of on-peak electricity using LNG at about 122 MW. The authors reported a round trip and storage efficiency of about 64% and 73%, respectively.
