The energy systems that will matter most this century share three properties: they are circular, they produce no emissions in operation, and they can be deployed wherever energy is needed rather than only where the grid reaches. iQ-LOOP is built around all three. At the centre is a simple idea: aluminium is one of the most energy-dense materials available, holding roughly 23.5 kWh per litre — close to ten times the energy density of liquid hydrogen. iQ-LOOP charges aluminium

For two decades, the limiting factor in technology has been compute, capital, or talent. That is changing. The binding constraint on the next wave of growth — artificial intelligence, advanced manufacturing, electrified industry — is energy, and more precisely, the ability to deliver firm, affordable power exactly where and when it is needed. The evidence is already visible. Britain's largest data centre, a £9 billion development in Bedfordshire, will run on its own gas gener
