Powering the Future: Cummins Introduces X15H and HELM™

Dieselspecialists – Powering the Future took center stage as Cummins, the global power solutions leader, showcased its latest innovations at the IAA Transportation Show in Hannover, Germany, in June 2025. In response to tightening Euro 7 emissions standards, Cummins introduced its next-generation internal combustion engines most notably the X15H and the advanced HELM™ platform.

These technologies are part of Cummins’ ambitious blueprint to transition heavy-duty transport toward cleaner, more efficient alternatives. The X15H represents a major leap forward in hydrogen-powered diesel technology, while the HELM™ (High Efficiency, Low Emissions Modular) architecture offers a flexible approach that supports diesel, natural gas, and hydrogen fuels providing a bridge between today’s infrastructure and tomorrow’s sustainable mobility.

The Role of HELM™ in a Hybrid Energy Future

Powering the Future means building adaptable systems, and Cummins’ HELM™ platform is designed exactly for that. This modular platform allows original equipment manufacturers (OEMs) to customize powertrains based on market needs and regional fuel availability. Whether used in long-haul trucks, construction equipment, or buses, HELM™ enables scalable adoption of lower-emission fuels without overhauling entire vehicle systems.

The HELM™ architecture also incorporates digital control systems and predictive analytics, which optimize fuel efficiency and performance in real-time critical capabilities as the transport sector strives to meet climate goals without sacrificing durability or cost-effectiveness.

Hydrogen Engines Enter the Mainstream

Powering the Future also means taking bold steps into hydrogen technology. The X15H hydrogen combustion engine, unveiled alongside HELM™, signals Cummins’ commitment to realistic, near-term decarbonization solutions. Unlike fuel cells, which require a complete redesign of power systems. Hydrogen ICEs (Internal Combustion Engines) allow faster industry adoption by using existing diesel platforms and manufacturing lines.

This approach not only accelerates deployment across developing and developed markets. But also lowers the economic barrier to clean energy transitions an essential move in achieving global emissions targets.
