Energy transmission options are discussed, with heat, electric power or fuel as the carrier of energy. Energy storage and retrieval technologies are surveyed, covering heat capacity, latent heat and chemical transformation stores of heat, and for electricity storage pumped hydro, flywheels, compressed gas stores, battery stores and hydrogen underground stores.

Energy Transmission and Storage

Availability of cheap power is an index of technological advancement and standard of living of a country. Conversion of solar energy into mechanical power or electrical power has been a subject of research for nearly last three centuries. Most of the early research conducted on solar mechanical power generation was for small power generation and was abandoned not due to technological reasons but more due to economically more viable and cost-effective power options. It is hoped that solar generated power will play a significant role by the end of this century.
