Blossom Energy G-TES 熱を貯めれば燃料は減らせる

G-TES

If you store heat,
Fuel consumption can be reduced.

Store Heat
 Reduce Fuel

A new kind of energy that supports everything from making and transporting to living.

Renewable energy is stored as heat, ensuring a stable supply and lower costs.

The BlossomEnergyG-TES graphite thermal storage boiler is a system that uses graphite as a heat storage material to store renewable energy-derived electricity as heat and supply it stably when needed. It can supply heat up to 500°C in various forms such as steam, hot water, hot air, chilled water, and chilled air, depending on the application. It decarbonizes heat utilization in various settings, from the hot water and steam demands of manufacturing sites to hot water and heating for entire buildings, and even cooling, while also reducing energy costs.

WHY GRAPHITE MATTERS

The challenge of "heat," which accounts for 70% of energy consumption.

Heat, which accounts for approximately 70% of global energy consumption, is still largely generated by burning fossil fuels. To realize a society primarily powered by renewable energy, technologies that utilize electricity as a stable and low-cost heat source are essential.
Blossom Energy is addressing this fundamental challenge.

Strengths of G-TES

Frame 95.png

Converting renewable energy into thermal energy usable 24 hours a day.

Surplus electricity generated from solar power and other sources is stored as heat. By utilizing electricity on weekends and during the day, weekday fossil fuel consumption and energy costs are reduced.

Frame 98.png

From 500℃ steam
Suitable for both hot and cold temperatures.

It stores heat at a maximum of 1,500°C, and can be used not only for heating but also for cooling.
