Carbon-neutral technology advances at Systems & Components 2025

Diesel engines remain predominant in agricultural mechanization, but share space with low-carbon solutions at Systems & Components 2025. The event, promoted by DLG (German Agricultural Society), takes place from November 9 to 15 in parallel with Agritechnica.

Currently, more than 80% of off-road mobile machines use diesel engines. According to experts, this reality should persist until 2035 for equipment above 56 kW. The appeal remains: robustness, low operating costs and fast refueling. However, manufacturers are investing in the evolution of combustion engines. Operation in lean mixture and advanced emission treatment stand out in the new generations of diesel.

The Systems & Components proposal: a neutral technological approach. Exhibitors adopt hybrid and versatile platforms, capable of operating with fuels such as natural gas, e-fuels and hydrogen. The highlight is solutions such as the Liebherr hydraulic air booster, which improves engine response in lean burn conditions and also in hydrogen applications.

Among the decarbonization routes, hydrogen combustion engines are gaining traction. Adapting to current production lines and infrastructure makes this technology viable for smaller-scale applications in the short term. Multi-fuel and dual-fuel engines expand the options, offering transition alternatives with lower environmental impact.

Renewing the existing fleet is also on the radar. Renewable fuels such as HVO and ethanol reduce up to 90% of CO₂ emissions and can be used in engines already in operation. Manufacturers such as Bosch develop injectors and components compatible with multiple fuels, favoring adaptation and operational continuity.

“The discussion about low-emission alternatives is mobilizing manufacturers of mobile machines. Even high-powered engines are in the focus of engineers, who are trying to comply with emissions limits and reduce fuel consumption,” says Petra Kaiser, Brand Manager at Systems & Components.
