In contrast with low-temperature electrolysis, HTE of water converts more of the initial heat energy into chemical energy (hydrogen), potentially doubling efficiency to about 50%. Because some of the energy in HTE is supplied in the form of heat, less of the energy must be converted twice (from heat to electricity, and then to chemical form), and so the process is more efficient.

DEFINITION of 'Cash Reserves '. In finance, cash reserves primarily refers to two things. One is a type of short-term, highly liquid investment that earns a low rate of return (perhaps 3\% annually) such as investment company Fidelity's mutual fund called Fidelity Cash Reserves.
