UK Startup Hits 800°C With Solar Power for Heavy Industry

Getting factories off fossil fuels just got a lot more realistic. UK startup Odqa has successfully heated air to 800°C using only concentrated solar power and used that heat in real industrial processes.

The company ran trials at Spain's Plataforma Solar de Almería, where giant mirrors focused sunlight to generate extreme temperatures. They proved the system works for heavy industries like metals, cement, glass, and ceramics that all need serious heat to make their products.

Here's the game changer: they also stored that solar heat in rocks. That means factories can keep running after sunset, solving one of solar power's biggest problems.

Back at their Oxford lab, Odqa took things further by melting aluminum using only hot air. No fossil fuels, no massive electricity draw, just captured sunlight doing work that typically requires burning coal or gas.

Industrial heat accounts for roughly 20% of all carbon emissions worldwide. Until now, most factories had no good alternative because regular solar panels and heat pumps can't reach the extreme temperatures heavy manufacturing demands.

"The reason most heavy industry hasn't decarbonised its heat isn't a lack of ambition, it's the lack of a solution that works," said Chris Kimmett, Odqa's CEO. His company is offering factories something they desperately need: a path to clean heat that actually works at industrial scale.

The timing matters more than ever. Volatile fossil fuel prices and supply chain disruptions have made energy costs unpredictable for manufacturers. Solar heat offers factories stable, long-term pricing while cutting their carbon footprint.

The Ripple Effect

This technology could transform entire industrial sectors that seemed impossible to clean up just a few years ago. Steel mills, cement plants, and glass factories around the world now have a proven option for hitting net-zero targets without shutting down or relocating.

The breakthrough also addresses energy security. Factories using solar heat don't depend on imported fossil fuels or geopolitical stability. They're generating their own industrial-grade temperatures from sunlight, free from price shocks and supply disruptions.

For communities near heavy industry, cleaner air becomes possible without job losses. Workers keep their livelihoods while emissions drop dramatically.

Heavy industry is finally getting the clean energy solution it's been waiting for.
