Siemens Energy has formed a partnership aimed at sustainably decarbonising the industrial sector with Norway-headquartered thermal energy storage company EnergyNest.
EnergyNest makes what it calls Thermal Batteries, where a specially formulated concrete (which the company has trademarked Heatcrete) is heated using high temperature heat transfer fluid (HTF) that passes through steel pipes inside the units. The company claims the energy can be stored with minimal heat loss, then as the battery discharges, cold HTF flows into the bottom of the battery unit and the heat comes out of the top.
The Thermal Batteries are intended to be modular and are housed in 20ft units, with modules designed to be transported easily and much of the pipework prefabricated and tested before being sent to project sites. The materials used are abundant, can be recycled and are non-hazardous while the startup claims systems can be cost-effective as well as compact, with high energy density and with little heat lost, scalable from MWh to GWh capacities.
With Siemens already having worked with EnergyNest including a 1MWh project begun in 2015 to verify the technology at Masdar City in Abu Dhabi, Siemens Energy – the spun-out business division of Siemens formerly known as Siemens Gas and Power – has signed a memorandum of understanding (MoU) with EnergyNest.
Targeting the development of their first commercial systems together within a year, the pair have formed a “long-term partnership to develop thermal energy storage solutions for industrial customers,” EnergyNest said in a press release sent to Energy-Storage.news.
