a) Compressed Air Storage b) Molten Salt Thermal Storagec) Hydroelectric Energy Storage d) Flywheele) Ice Storage Nicholas Kraft 8

Advantages Conceptually simple Eliminates combustion in the case of a boiler therefore virtually eliminating issues involving emissions. Disadvantages Multiple energy conversions lead to possible inefficiencies Molten salt or other heat transfer fluid is expensive Danger of storing high temperature material Multiple storage tanks consume a substantial amount of space.

Advantages Efficient Very little if any emissions Cost efficient relative to other concepts Safe operation Could add a thermoelectric concept (not likely but still an option) Disadvantages Relatively complex Requires high insulation to prevent heat transfer from the environment into storage tank. Size constraints Nicholas Kraft 11
