MGA Thermal’s Energy Storage System (TESS) offers a scalable means of firming variable renewable generation into process-grade heat between 150°C and 600°C for industrial processes, heat & power (cogeneration) or electricity generation. The TESS is highly efficient and economically delivers 200% to 300% higher energy density than other thermal energy storage materials.
The MGA technology is a purpose-invented material called Miscibility Gap Alloy (MGA), which is manufactured as MGA Blocks. MGA Blocks store and deliver thermal energy while remaining outwardly solid.
The MGA TES system works by converting renewable electricity into heat through resistive heaters, which is then absorbed by the MGA Blocks. The MGA Blocks store heat efficiently within an insulated environment for days or weeks.
Resistive heating elements convert renewable electricity into heat, which is absorbed by the MGA Blocks.
Inert gas runs over the Blocks, delivering heat to an HRSG to produce steam from 150 to over 650 Celsius, at a market-leading round-trip efficiency.
When used for co-generation, this steam passes through a turbine and a HRSG to provide flexible, firmed 24/7 renewable heat and electricity.
MGA TESS can charge and discharge simultaneous for flexible operation and scale to GW thermal.
