The global energy sector is transitioning to renewables with the likes of electric cars which intend to dominate the industry. One of the crucial things associated with this trend is how to store energy while maintaining it as clean energy.
The pronounced trend currently is storing renewable energy from solar and wind energy farms via the battery facilities. Scientists are exploring the possibility of storing heat or thermal energy in this way. Aurora Research reveals that the market size for heat storage commands three times the market of electricity storage.
Energy from wind and solar systems is stored in electric battery storage systems and before distribution to various customers from the power producers. On the other hand, heat from operations like brick making and steel manufacturing is stored in thermal energy storage for reuse by these industrial faculties.
Thermal batteries are going to play a vital role in the decarbonization of the industrial sector. An Italian oil and gas producer Eni states that sectors like metal industry, chemicals industry, and textile industry can minimize global warming by storing the exothermic energy from the systems in thermal batteries for later reuse. The firm thinks that this is a better way to save on power costs.
Heat energy is more useful than electricity because asides from generating power, it can be used as heat in heating systems at home or preheating and steam generation in industrial processes. The chief executive of EnergyNest Christian Thiel says that they are developing a concrete-like material to store heat. He explains that few resources are essential in the development of the production facilities of this concept. The storage system is known as Heatcrete and is composed of 75 percent quartz.
The Heatcrete composes of physical materials that are non-biodegradable and therefore, will last for over ten years. The system’s modular nature allows the manufacturer to add capacity to the existing material and still function properly. After installing this battery, EnergyNest can monitor the practical usage of the energy using operating software. EnergyNest has been exploring this technology and is rolling it out on a commercial scale. This rollout is currently ongoing at the Sicily center in Austria.
Finally, EnergyNest is collaborating with firms like Siemens Energy to create thermal energy storage systems for their industrial customers. Thiel explains that the primary mission of such collaborations is to decarbonize the sector and turn the heat waste into an energy source. This move is to halt the usage of fossil fuels like gasoline and diesel.
