We believe energy for humans shouldn’t bother the planet

That is why we decouple energy from fuels and emissions
by building a super-star on earth.

In the sun, hydrogen nuclei combine with each other to form helium and release energy.

 

Stellarators (from ‘stella’, Latin for ‘star’) are the most efficient, steady and stable fusion devices on earth.

At Renaissance Fusion we build (in)credible magnets and liquid metal shields to bring stellarators out of the lab and onto the grid.

Who we are

We’re rebels rooted in solid science, we think creatively outside the box and re-invent the engineering, under economic constraints.

As the only magnetic confinement fusion start-up in continental Europe, we work in a region that is home to 40% of the world’s talent, labs, universities in the field, and, with ITER, has fostered a unique ecosystem of related industries.

In 2050 we will need to meet 2x the current energy demand, at zero CO2 emissions.

We will need renewables, energy storage and a safe, abundant, load-following, fuel- and land-efficient energy source.

Fusion is that source.

We build (in)credible magnets and shields

Stellarators are the most efficient, steady and stable fusion devices.
In addition, we make them

  • SMALLER and even more efficient thanks to strong magnetic fields generated by High Temperature Superconductors (HTS)

  • SIMPLER thanks to disarmingly simple “coil winding surfaces” and revolutionary HTS magnets, directly deposited and patterned on large surfaces

  • RAMI (Reliable, Available, Maintainable, Inspectable), publicly acceptable, easier to license, thanks to modular vessels and flowing liquid metal walls that prevent neutron damage and bring the radioactivity down to hospital levels

and therefore the best route to net fusion energy

 

  • Milestone 1

    Prove HTS and liquid metal walls in 3 years Ready for immediate commercialisation in areas like energy storage and medical imagine

  • Milestone 2

    Build first small
    reactor in 6 years

  • Milestone 3

    First full size net energy
    stellarator in 10 years

  • Unlimited, sustainable energy

  • Jumpstarting the green hydrogen economy.

  • Powering the future of clean mobility

With a bathtub of seawater and the lithium found in two laptop batteries, we can generate energy for a person’s lifetime.

We create a solution for a $1 trillion a year addressable fusion market. With no proliferation, meltdowns or fission waste.
