MGA Thermal’s thermal energy storage system (TESS) offers a scalable means of firming variable renewable generation, storing heat at up to 650^oC to supply heat for industrial processes, heat & power (cogeneration) or for electricity generation.

The MGA technology is a phase change material called Miscibility Gap Alloy (MGA). MGA Blocks store energy as latent to achieve a high energy density while remaining outwardly solid.

The MGA TESS works by converting renewable electricity into heat using resistive heaters, which is then absorbed by the MGA Blocks. The MGA Blocks store heat efficiently within an insulated environment for days or weeks. A closed-cycle gas loop is used to transfer heat to an HRSG to produce steam at the required temperature and pressure.

Why work with us

Key target markets for MGA’s TESS include chemical production, refining, mineral processing, paper, packaging, rubber, food and beverage.

MGA Thermal's proprietary technology is the Miscibility Gap Alloy (MGA) material, which is designed for optimal thermal storage characteristics. The core advantages that make MGA's thermal storage system economically compelling are:

1. Electrify industrial heat: Convert intermittent renewable electricity into heat, and discharge stable, continuous, high-grade process heat at up to 550C for industrial processes.
2. High energy density: 200-300% energy storage capacity of alternate thermal energy storage systems to achieve a compact footprint.
3. Scalable from MWh to GWh: Economically scale to GWh storage capacity. Independently size charging, storage and discharge equipment for client-specific needs.
4. Seamless Integration: Provide stable, continuous steam at the required set point temperature and pressure for seamless integration with existing plant.
5. Flexible charge & discharge: Charging and discharge are decoupled to enable 24x7 continuous power. Rapid charging response time (<100ms) to access DR and network services.

Globally, about 45% of industrial heat demand falls within the MGA focus temperature range of 150°C to 650°C. To fully decarbonise, many industrial processes require affordable access to continuous power from low emissions sources, at high temperatures and at GWh+ scale. The path to Net Zero by 2050 relies on emerging technologies.
