Can you imagine a future where the production of steel, cement and glass, traditionally energy-intensive and highly polluting processes, are powered by simple bricks? No, I'm not talking about medieval alchemy, but about a technological innovation that could revolutionize industry and bring us closer to a more sustainable future.
A North American company, Electrify Thermal Solutions , has developed a conductive brick capable of storing energy at extreme temperatures (around 3,000º Fahrenheit) and releasing it on demand, opening up a range of possibilities to decarbonize key industrial sectors. And I have to admit that the news has left me speechless, in the hope that it is true.
The idea itself is brilliant in its simplicity: bricks, a ubiquitous and relatively cheap construction material, transformed into high-temperature energy storage devices. These bricks, unlike traditional bricks, are conductors of electricity. This allows them to self-heat by passing current through them, eliminating the need for ovens or external heaters, which simplifies the process and reduces energy losses.
The real magic lies in their ability to reach the very high temperatures required in industries such as steel, cement and glass. Imagine the power contained in a wall of these incandescent bricks, ready to be released and used in metal smelting or glass production.
The most significant implication of this technology is its potential to transform traditionally polluting industries into sustainable processes. Currently, these industries rely heavily on fossil fuels to reach the high temperatures required, generating huge amounts of greenhouse gas emissions.
With these bricks, the energy used to heat them could come from renewable sources, such as solar or wind. And here comes another key point: the possibility of storing energy. The bricks could be charged (i.e. heated) during hours of lower energy demand, when renewable electricity is more abundant and cheaper, and used at a later time when demand is higher, providing a constant and clean source of heat for industrial processes.
This not only reduces dependence on fossil fuels, but also offers a solution to the problem of intermittent renewable energy. The sun does not always shine, and the wind does not always blow, but the energy stored in these bricks would be available 24/7, ensuring the continuity of industrial production. It is a win-win scenario: industries reduce their carbon footprint, renewable energy is used to its full potential, and the fight against climate change is contributed to.
The company behind this innovation plans to have pilot facilities up and running by the end of next year. These tests will be crucial to demonstrate the viability of the technology on an industrial scale and to assess its efficiency and long-term durability. Scalability of production is also a key factor in its success. If production of these bricks can be scaled up efficiently and economically, their impact on industry could be truly transformative.
However, it is important to remain cautious. Although the outlook is promising, many questions remain. What will be the real cost of producing these bricks on a large scale? How will the life cycle of these bricks be managed once they reach the end of their useful life? What impact will this technology have on employment in the affected industries?
Despite these uncertainties, the idea of bricks that store energy at high temperatures is not new, and there are others who use it. The difference with Electrify Thermal Solutions' proposal is that its bricks are conductive and are heated to higher temperatures, which are needed in very demanding industrial processes such as cement, steel, glass, etc….
The proposal represents an innovative and potentially disruptive solution to a crucial problem: the decarbonisation of heavy industry. If the pilot tests are successful and production scales as expected, we could be at a turning point in the transition towards a cleaner and more sustainable energy future. We will closely follow the development of this technology and hope that we will soon be able to confirm with facts what today promises to be a revolution in the energy sector. The future, it seems, could be built with red-hot bricks.
