A new study in Germany shows the benefits of thermal energy storage in the low -carbon of industrial processes. The researchers saw clear cost benefits and a high potential for flexibility in the PowerNet.
Kraftblock, a specialist based in Germany in the field of thermal energy storage, has published a 30 -page study with German consultancy DWR Eco on the benefits of thermal energy storage for electricity networks and renewable electricity production.
The generally positive findings of the study are not surprising, but can still attract attention by emphasizing the broader economic benefits of technology.
Thermal energy storage systems can be loaded with waste heat, in particular through industrial processes, or storing electricity and energy as heat up to 1,300 ° C. The researchers said these systems match heavy industries such as steel, metal processing and chemicals, where process heat is good For a maximum of two -thirds of the demand for industrial energy.
The study is investigating how thermal storage can deliver process heat and at the same time support electric gratings in important markets, including the United States, Europe and Australia. It also compares the benefits of technology in relation to hydrogen and direct electrification. The study shows that industries in Germany can lower electricity costs by a maximum of 30%.
“The results show that the technology is much cheaper and much more efficient than hydrogen and also cheaper than direct electrification,” said Martin Schichtel, director and co-founder of Kraftblock.
In the extreme price environment of Australia, storage systems can achieve returns of more than 150%. High and long -term negative electricity prices, together with large spreads between negative and subsequent positive prices, create arbitration options, making storage a “net positive scenario”. In 2023, the negative electricity prices accounted for 20% of the total market hours.
Germany is also confronted with a growing need for schedule flexibility, so that thermal energy storage “is not only a technological advantage, but essential for energy systems and industries,” said Kraftblock co-founder Susanne König. These systems cost a fraction of large batteries and offer a longer energy storage time.
