About Marathon Fusion
We are building the fuel cycle for fusion energy on climate-relevant timelines to accelerate the deployment of this critical energy resource. By working alongside universities, national labs and industry partners to commercialize critical technologies, we aim to ensure the safe and economic deployment of fusion energy at meaningful speed and scale.
Marathon is supported by some of the energy industry's leading investors, alongside grant funding from the US Department of Energy&rsquo;s ARPA-E and the Breakthrough Energy Fellows program.
