At some point in the dawn of humanity, a smarter-than-average homo sapien moved a rock away from the fire for warmth and invented the thermal battery.
Over a million years later, as humanity struggles to evolve past fossil fuels in time to avoid climate collapse, that simple idea is making a modern comeback – and hot rocks are hotter than ever.
Now, if successful, start-up Antora Energy could be part of a new, multi-trillion-dollar energy storage sector that simply uses sun or wind to make boxes of rocks hot enough to run the world’s biggest factories.

Waste management and resource recovery remain essential to circular progress. The Department for Energy Security and Net Zero’s recent review identified strong potential for circular construction strategies and end‑of‑life reuse in construction to deliver quantifiable carbon savings. Yet challenges persist in the rollout of Simpler Recycling due to legacy property structures. Strengthening these back‑end systems ensures green building products re‑enter value chains, supporting both circular economy objectives and sustainable urban development. The collective impact across policy, design, education, and technology confirms that the carbon footprint of construction can be reduced dramatically when the sector treats sustainability as an integrated, measurable discipline rather than an optional ambition.
Whole Life Carbon is a platform for the entire construction industry—both in the UK and internationally. We track the latest publications, debates, and events related to whole life guidance and sustainability. If you have any enquiries or opinions to share, please do
