Solar Integration: Solar Energy and Storage Basics
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.

Metal hydrides for concentrating solar thermal power energy storage
1 Introduction. Thermal energy storage using metal hydrides has been explored since the mid-1970s [ 1] but was generally applied at temperatures below 200 °C due to the limited number of hydrides known at that time. In the early 1990s, the development of low-cost magnesium hydride (MgH 2) with rapid hydrogen (H 2) sorption …
