MGA Thermal

Empowering renewables through thermal energy storage

Alexander Post CTO

MGA Thermal technology is a newly invented type of thermal storage material, Miscibility Gap Alloys (MGA). These alloys can store a huge amount of energy as heat, in a safe and easy to use way.
Modular blocks of MGA are stacked into insulated storage tanks, which can store energy for use in a range of applications – improving the electrical grid’s stability, residential and commercial space heating, industrial process/waste heat, and even electric vehicles. Their first focus though, is enabling intermittent renewable energy sources such as the sun and wing, to provide base load electricity to the grid.

What (and whose) problem is your company trying to solve?

We are solving the problem of how to firm and dispatch renewable energy on demand by providing an affordable, scalable, medium duration energy storage solution. This helps renewable energy generators by creating a market in times of oversupply of renewables, manufacturing companies by providing a source of firmed thermal energy from renewable sources and thermal power station asset owners by enabling retro-fit.
