Temperatures can be hottest during these times, and people who work daytime hours get home and begin using electricity to cool their homes, cook, and run appliances. Storage helps solar contribute to the electricity supply even when the sun isn''t shining. It can also help smooth out variations in how solar energy flows on the grid.

The advantages of LH 2 storage lies in its high volumetric storage density (>60 g/L at 1 bar). However, the very high energy requirement of the current hydrogen liquefaction process and high rate of hydrogen loss due to boil-off (∼1–5%) pose two critical challenges for the commercialization of LH 2 storage technology.
