Abstract
Abstract A thermochemical energy storage and mechanical energy converter system utzing a turbine. The system has a power or discharge phase, and a reactivate or charge phase. In the power phase ammonia gas is released by CaCl 2 .8NH 3 , expanded in a turbine and combined with ZnCl 2 to form ZnCl 2 .NH 3 . In an example of the reactivate phase, ammonia gas is released by ZnCl 2 .NH 3 and added to CaCl 2 .NH 3 to form CaCl 2 .8NH 3 .
