Storability is another important attribute of the chemical fuel hydrogen. Hydrogen makes it possible to economically store over time—for the winter season, for example—energy derived from intermittent sources such as solar power. Hydrocarbons (natural gas, petroleum, coal) obviously are easy to store. But how do you store sunlight or the heat from a nuclear reactor Storage works very well in solar power tower plants, where heat is stored very efficiently in 24-hour, day-and-night cycles in molten salt storage tanks.2...
