A recent study from Stanford University reveals that ancient technology, specifically the use of thermal bricks, could play a pivotal role in the transition to clean energy. Published in the journal "BNAS Nexus," the research suggests that these bricks, made from sustainable materials, could help achieve the United Nations' goal of net-zero emissions by 2050. Unlike traditional battery storage, thermal bricks store heat rather than electricity, making them ten times less expensive and an attractive option for industrial applications.
Professor Mark Jacobson, the lead researcher, explains that the technology involves assembling these bricks in insulated containers, where they can store heat generated from renewable energy sources like solar and wind. This stored thermal energy can be utilized in industrial processes, ensuring continuous operation even when renewable energy sources are unavailable. The study indicates that implementing thermal brick technology could reduce capital costs by approximately $1.27 trillion compared to battery-dependent solutions, enhancing the reliance on renewable energy.
Despite the advantages, challenges remain in adopting this technology, particularly for existing factories. Jacobson emphasizes the need for government policies and incentives to facilitate the transition. He envisions thermal bricks as part of a broader strategy to achieve 100% clean energy, addressing fluctuations in renewable energy supplies and providing a sustainable solution for large industries.
- The historical significance of refractory bricks dates back to the **Bronze Age**, where they were used in ancient ovens and iron furnaces. These bricks are composed of materials similar to clay and sand, making them environmentally friendly. Jacobson highlights that thermal bricks can provide about 90% of the heat required for high-temperature industrial processes, ranging from 150 to 2000 degrees Celsius. In light of the urgent need for sustainable energy solutions, thermal brick technology exemplifies how ancient methods can be innovatively applied to modern challenges. With appropriate government support, this technology could significantly contribute to a zero-emissions future.
