The path to CO2-neutral mobility is one of the most urgent challenges of our time. With over 1.5 billion vehicles on the world’s roads, the transition to sustainable energy carriers - such as renewable electricity, hydrogen, and eFuels - and the further development of next generation engines and powertrain systems including life-cycle evaluation is more critical than ever.

The conference Sustainable Energy & Powertrains (former Conference on Powertrains with Renewable Energy Carriers), taking place on November 25 - 26, 2025, focuses on the critical topics shaping the future of CO₂-neutral mobility. Targeting professionals from industry, academia, and policy-making, the event explores challenges and innovative solutions involving renewable electricity, hydrogen, and sustainable fuels. The conference also features a trade exhibition, offering attendees the opportunity to connect with cutting-edge technologies and leading industry stakeholders.

The following topics are planned:

• Energy infrastructure build-up, bottlenecks and challenges in renewable electricity, hydrogen, renewable fuels incl. life-cycle evaluation
• Powertrain electrification, hybrids, fuel cells and battery technologies
• High efficiency development in combustion processes and exhaust gas aftertreatment
• Lower carbon intensity fuels (e.g. hydrogen, eFuels, bioFuels) and carbon neutrality in motorsports
• Global market development and political framework for carbon neutrality
