Introducing the MGA Block.
MGA Thermal unlocks zero-carbon renewable energy storage for grid and industrial use.
Our blocks consist of a purpose-invented material called Miscibility Gap Alloy (MGA). MGA Blocks are used in Thermal Energy Storage Systems (TESS) which deliver sustained high-temperature heat or electricity that is safe, low cost, sustainable, and high capacity.
MGA Blocks store and deliver
thermal energy
while remaining outwardly solid.
How do MGA Blocks work?
The MGA technology is a purpose-invented material called Miscibility Gap Alloy (MGA), which is manufactured as MGA Blocks.
The blocks are designed with two key materials. Tiny metal alloy particles are dispersed through a matrix material. These particles melt as the blocks are heated and energy is absorbed, while the matrix material remains solid and keeps the molten particles in place.
The energy is stored in the solid-to-liquid phase change and is released as the blocks cool and the particles become solid again.
MGA Blocks are used in Thermal Energy Storage Systems (TESS) which deliver continuous high temperature heat or electricity that is safe, low cost, sustainable and high capacity.

“MGA Thermal have a ground-breaking energy storage solution. They represent the next generation of energy innovators.”
