5 Where is TMES really Great ? Large capacity: 100’s of MWh to GWh >90% Elect-thermal round trip efficiency Zero Green House Gas emissions Utilize all the heat for greatest efficiency Charge off-peak, deliver on peak Our planet must convert from fossil fuels to renewable electricity while businesses still make money

Our focus: Large (>10MWh) thermal energy storage to: Lower GHG emissions by reducing fossil fuel use Lower the cost of production in the process
