Marathon Fusion, a pioneering startup in the fuel processing technology sector for the fusion industry, has successfully raised $6.9 million in a new funding round. This financial boost was led by 1517 Fund and Anglo American, with significant contributions from Übermorgen Ventures, Shared Future Fund, Malcolm Handley, and other prominent investors. Additionally, Marathon Fusion received a CREATE award from the Department of Energy’s ARPA-E, further solidifying its financial foundation.
Founded in 2023, Marathon Fusion is on a mission to enhance fuel processing efficiency, a critical component in the quest for clean and scalable fusion energy. Fusion energy holds the promise of providing clean, affordable, and reliable power at a terawatt scale. However, achieving this vision requires the capability to process fusion fuel at a high throughput to meet the demands of commercial power plants. Marathon Fusion’s innovative technology addresses this need by enabling fusion power plants to operate with reduced tritium inventory. This advancement allows for smaller facilities and lowers operational expenses, making fusion power more economically viable.
Early in its journey, Marathon Fusion was supported by the Breakthrough Energy Fellows program, which provides crucial support to early-stage technologies aimed at combating climate change. This program offers capital, mentorship, education, and access to the extensive Breakthrough Energy network, helping bridge the gap between laboratory innovation and market readiness.
With its new funding, Marathon Fusion is poised to accelerate the development and deployment of its cutting-edge fuel processing technology. The company has already signed Letters of Intent with Commonwealth Fusion Systems and Helion Energy, two leading fusion startups that are at the forefront of bringing fusion power plants to market. By commercializing its technology, Marathon Fusion aims to facilitate rapid, efficient, and high-throughput processing of fusion fuel, thereby reducing onsite tritium inventories and improving the economic feasibility of fusion power plants.
Marathon Fusion’s advancements in fuel processing technology are set to play a pivotal role in the energy transformation, ensuring that fusion energy can scale to its full potential and contribute significantly to a cleaner and more sustainable energy future.
