Currently, at the Carty Power plant located in Boardman, Oregon, a stream of high-pressure saturated water is produced as a by-product of their natural gas-fueled electricity generation. In the current power plant design this waste heat stream is sent to a flash drum and all the thermal energy stored in the water is lost to the surrounding environment. The objective of this project is to make use of this wasted thermal energy and store it in the form of chemical potential through reversible chemical reactions. This method, known as thermal chemical energy storage (TCES) will allow this unused thermal energy to be stored potentially indefinitely for later use at the power plant. The current design developed by Triple D enterprises involves a TCES heat exchanger loaded with a salt hydrate that is charged through a dehydration reaction and discharged through a hydration reaction. This reaction chemistry paired with the current heat exchanger model is able to produce roughly 140 GJ/yr, energy normally, that would be lost to the surrounding environment.
