A big debate in the field of nuclear fusion is which concept would win on economics. Tokamak, stellarator or tandem mirror? Closed-field or open-field? Magnetic confinement or inertial fusion? Every fusion company has a favourite. The trouble is, analyses aren’t comparing like with like. One team's tokamak costing may assume a friendlier magnet supply chain than the stellarator team down the hall assumed for theirs. So when someone asks the question that actually matters to an investor, a...

I joined nTtau Digital as an intern in my final year of university, before I even had my degree. At the time, I could never have imagined how much the company was going to grow, or how much I would grow alongside it. I didn't know I'd still be here two years later, but something about the problem, and the people trying to solve it, made me stay. After graduating in 2024, I returned on a rolling internship. For the next year, we delivered simulation services to customers - individual projects...

The Potential of Fusion Fusion energy has long been one of science’s most ambitious goals, and it’s easy to see why. If it can be made reliable and economical, it offers a path to abundant, clean electricity that strengthens both climate goals and energy security. The European Commission's Energy 2050 Roadmap highlights five scenarios achieving an 80% reduction in greenhouse gas emissions through nuclear energy, renewables, and carbon capture and storage, highlighting nuclear power as key to...
