on Renaissance Fusion

  • Renaissance Fusion is a hardware R&D company with the goal of designing, building, and commercializing a fusion power-plant based on the stellarator, HTS and liquid metal technologies, on time to contribute solving the climate crisis caused by carbon emissions.

  • In 2019 our founder Francesco Volpe presented in New York and Milan the idea of creating the first magnetic fusion start-up in Europe. In October 2019 he visited 5 candidate cities in France, the Netherlands and Spain. In 2020 he moved to Grenoble, France, where in July he officially registered the company.

    Francesco chose to create a private start-up (not spun off from any university or public laboratory) to offer an alternative path to fusion: imbued with scientific rigor and academic collaborations, and yet fully relying on the agility and speed of a start-up.

  • We are a single, multi-disciplinary company organized in 5 teams developing 3 technologies: one team on HTS film deposition, one on liquid metals and three on fusion science and engineering. The 5 departments share business, admin and technical resources, and frequently discuss and exchange with one another, for good reasons: far from being a random collection of good ideas, the three techs are highly synergistic to each other. To make an example, HTS generate strong magnetic fields that facilitate the levitation of current-carrying liquid metals; at the same time, thick Li-based liquid walls shield the delicate HTS from damage by fusion neutrons.

    Spin-offs on HTS or liquid metals are not excluded in the future, but for now and for the foreseeable future we are fully dedicated to the holistic project.

on IP, publishing and collaborations

  • We are self-aware dwarfs on giants’ shoulders, thankful for the body of knowledge published by public labs over the decades, eager to “give back” and jointly advance fusion. For this, we regularly present our results at conferences, we have published or recently submitted several journal articles, and we welcome scrutiny by the scientific community. At the same time, to protect some findings from unauthorized commercial exploitation, we ask our scientists and engineers to “patent first, publish later” (or to be precise, submit the patent application first, then the paper -without waiting for the patent to be granted). The good news is that patent applications are much faster to write, and no scientific paper has been delayed in this process.

  • We already have several collaborations in Europe and the USA (see https://renfusion.eu/people) and are constantly on the look for more collaborations with public organizations and, on selected topics, with private companies. The only criteria are that collaborations be mutually beneficial, and that timescales, cultures and risk-profiles are reasonably well-aligned. Fair warning: we strive to be fast and explore unbeaten paths, with the result that either we will publish a major paper together, or none. Steady streams of incremental papers are not our forte. Other than that, sky is the limit and there are more and more grant opportunities for public-private partnerships. If you have an idea for a collaboration, send us an email at contact@renfusion.eu !

  • There are several formats:
    — Informal collaboration: each organization pays for its scientists/engineers to realize a design, simulation, or experiment, or build an instrument or device of common interest. Ideally, the organizations will complement each other’s strengths. The topics, a rough roadmap and division of roles can be agreed in a memorandum of understanding of a couple of pages – we like to keep things simple.
    — RF and the French government, through the CIFRE program, can co-sponsor a PhD thesis at a French university.
    — RF and a university, anywhere in the world, can co-sponsor a PhD thesis or post-doc.
    — Joint grant application to a French, Swiss or European program admitting or even encouraging public-private partnerships. As a start-up, it might be a win-win if we partner with universities, national and international labs, and select large companies. For international applications, as a French- and Swiss-based organization, it might be good to partner with organizations in other countries.

on funding

  • We are a pre-revenue company at the product development stage, primarily financed by external funds. After an Angel round in June 2021, we closed a Seed round in May 2022 with several international VCs, for a total of approximately 16 M€. Our investors include Lowercarbon Capital, Positron Ventures, Norrsken VC, HCVC, Unruly Capital, Excellis, and Exor Ventures. In addition, we received small grants from BPI France in 2020 (“Bourse French Tech Emergence”) and from the INFUSE program in the USA, in 2021-22. In November 2023 we were awarded a 10 M€ grant in response to the Call for Proposals “Innovative Nuclear Reactors” organized by BPI France in the framework of the France 2030 program. As part of the award we will also receive “in kind” help from CEA institutes in Cadarache, Grenoble and Saclay, worth several millions. That was phase 1 of a 3-phase program. Grants of up to 80 M€ and 300 M€, respectively, will be made available in phase 2 and 3.

  • At the moment we have no EU projects running, but we look forward to forming consortia with universities, national labs and industrial partners in 2-3 EU countries and jointly applying for funding. We are especially interested in complementary skills and technologies. Together we will bring HTS, liquid metal and fusion inventions closer to market and societal impact.
