Abstract
Behind the meter electrical energy storage in buildings as a means of peak shaving and time-of-use shifting has been demonstrated to provide utility bill savings in buildings with high electricity demand, while simultaneously relieving strain on the electric grid during peak periods. Batteries have dominated the building energy storage market but are still expensive and have a relatively short lifetime. The Ground Level Integrated Diverse Energy Storage (GLIDES) system is a newly invented electric energy storage technology which can leverage waste heat to improve its round-trip efficiency (RTE) and energy density and lifetime. It has demonstrated an RTE of 51.6% in laboratory testing, and modeled improvements demonstrate the potential for 75% RTE. This paper reports on the development of GLIDES and its potential value in buildings.
