There are now more than 1.5 billion vehicles on the world's roads. Many are powered by fossil based fuels or electricity. Electromobility makes a very important contribution on the way to local CO₂-neutral mobility and a rapid reduction in CO₂ emissions from road traffic can only be achieved by including the existing fleet.

To enable a sustainable transition, renewable energy sources and sustainable energy carriers are essential across all mobility solutions. Alongside powertrain electrification, hydrogen and eFuels offer globally viable pathways toward achieving CO₂-neutral mobility.

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:

• Powertrain electrification, hybrid and combustion technologies incl. fuel cells
• Energy infrastructure build-up, bottlenecks and challenges in renewable electricity, hydrogen and renewable fuels
• Carbon-neutral fuels (hydrogen, eFuels, bioFuels)
• Battery technologies
• High efficiency development in combustion processes and exhaust gas aftertreatment
• Carbon neutrality in motorsports
• Global market development and political framework for carbon neutrality
