Spark e-Fuels Selected as Breakthrough Energy Fellow
Spark’s demand-responsive e-fuel technology recognized for its potential to cut SAF costs and accelerate industrial decarbonization
Berlin (Germany), September 11, 2025 – Spark e-Fuels announced today that it has been chosen to participate in Breakthrough Energy’s prestigious Fellows Program to advance its unique demand-response e-fuel process to produce urgently needed Sustainable Aviation Fuel (SAF) at the lowest possible cost. BE Fellows supports early-stage innovators who are developing technologies with the potential to significantly reduce greenhouse gas emissions at scale.
“We’re honored to have the opportunity to work with talented founders who are tackling the most difficult climate and energy challenges around the world,” said Ashley Gross, vice president of Breakthrough Energy. “We share their long-term vision and early-stage commitment, and our mission is to help these innovators build strong business and technical foundations for the best opportunity for success.”
BE Fellows receive funding, tailored technical guidance, and access to Breakthrough Energy’s global network of mentors, experts, and partners. The program helps founders bridge the gap from lab to market and advance their solutions toward commercial readiness.
Spark e-Fuels was chosen as part of the 2025 class of Fellows, which includes 45 Fellows across 20 pioneering companies. This group includes innovators working across electricity, transportation, buildings, manufacturing, and agriculture. Half of the teams selected are based outside the United States, reflecting the program’s global reach and commitment to building an international community of climate entrepreneurs.
Spark is addressing one of the most significant barriers to scaling synthetic Sustainable Aviation Fuels (e-SAF): high production costs. With a demand-responsive system designed to operate flexibly with the lowest-cost, variable renewable energy sources, Spark enables a fundamental shift in e-fuel and chemical feedstock production. This innovation significantly reduces the cost of green molecules, unlocking a scalable and economically viable path to decarbonizing aviation and the broader chemical industry.
“Being selected as a Breakthrough Energy Fellow is an incredible opportunity to accelerate our mission of making e-fuels a scalable and cost-effective solution for aviation and beyond,” said Co-Founder & CEO Mathias Bösl. “With this support, we can focus on advancing our demand-responsive technology and preparing it for deployment at an industrial scale.”
Since its launch in 2020, BE Fellows has supported more than 160 innovators across nearly 20 countries. Alumni have secured over $475 million in follow-on funding, filed 175 patents, and completed more than 80 pilots and demonstrations.
