The climate impact of Azelio’s energy storage system (TES.POD) is significantly less than that of lithium-ion battery storage and dramatically less than that of diesel generators. Concluded in a Life Cycle Assessment made by the Swedish research institute RISE to determine Azelio’s TES.POD’s global CO2-equivalent emission during its entire lifetime.
The report shows that the climate impact of Azelio’s system per unit electric energy supplied is 23 g CO2/kWh, which is 29% lower than a Li-ion battery system and 96 % low than a high-efficiency diesel generator (523 g CO2/kWh). The study thus disregarded that Azelio’s system also delivers a significant amount of heat that can be utilized as energy in many applications.
The study approach includes transportation and production of materials and components, manufacturing of equipment, transport, assembly and installation of components and operation. More than 650 components per Azelio’s TES.POD unit were included as well as melting of the storage material. In this study, it was assumed that both the TES.POD and Li-ion battery would be charged by a carbon-free energy source and therefore not generate any direct emissions during their lifetime.
Azelio’s unique energy storage technology stores energy from solar and wind power as heat in recycled aluminium and generates electricity and heat on demand at all hours of the day to a low cost. The system suffers no degradation over time and is fully recyclable at end-of-life. It is modular and cost-effective from installations at 0.1 MW up to installations of 100 MW.
