Bosch Unveils Next-Generation Powertrain Innovations to Cut CO₂ in Construction Machinery

(IN BRIEF) At bauma 2025, Bosch will showcase its latest powertrain solutions designed to reduce CO₂ emissions from construction machinery. The company is focusing on three main strategies: the use of renewable synthetic fuels such as HVO100, the development of hydrogen engines adapted from conventional combustion technology, and the expansion of electrification solutions. Renewable synthetic fuels offer an immediate, drop-in solution that can lower the carbon footprint of both new and existing diesel-powered vehicles, aided by Bosch’s Digital Fuel Twin software, which certifies fuel sustainability. Bosch also plans to leverage its extensive experience in combustion engines to accelerate the adoption of hydrogen engines, which promise high efficiency and robust performance for heavy-duty applications. Additionally, electrification options are being expanded through Bosch Rexroth’s eLION portfolio and Bosch Engineering’s high-voltage electric powertrain systems, addressing both mobile and stationary needs in construction machinery. These efforts collectively aim to transform the sustainability of construction vehicles, ensuring that even as diesel remains prevalent, its environmental impact is significantly mitigated.

(PRESS RELEASE) STUTTGART/ MUNICH, 7-Apr-2025 — /EuropaWire/ — At bauma 2025, Bosch is set to demonstrate innovative strategies for reducing CO₂ emissions from construction machinery by harnessing renewable synthetic fuels, hydrogen engines, and electrification technologies. Despite the durability and strength that have made diesel engines the industry standard—powering over one million new construction vehicles projected worldwide in 2025—Bosch is pioneering solutions to make these machines more environmentally friendly.

Jan-Oliver Roehrl, Executive Vice President of Bosch Power Solutions and Head of Commercial Vehicle Activities, emphasizes that renewable synthetic fuels like HVO100, derived from residual and waste materials, offer a practical way to lower carbon footprints. These fuels, which can be blended with conventional diesel, are fully compatible with Bosch’s advanced injection systems. Additionally, Bosch’s Digital Fuel Twin software provides a detailed record of fuel consumption and sustainability—from production to refueling—allowing operators to receive certification for reduced carbon emissions based on their fuel use.

Looking ahead, Bosch anticipates that four out of every five new construction vehicles with more than 56 kilowatts will continue to utilize diesel engines well into 2035. Consequently, Bosch is further developing its injection and urea dosing technologies to accommodate these engines across a wide array of construction machinery segments.

In parallel, Bosch is adapting well-established combustion engine technologies to hydrogen engines, where approximately 80 to 90 percent of the components can be repurposed. With renewable energy as the hydrogen source, these engines are positioned to significantly enhance the sustainability of heavy-duty, stationary construction machinery and even serve as the powertrain for robust dump trucks in mining operations. The first hydrogen engine applications using Bosch injection technology are set to launch this year.

Furthermore, electrification is emerging as a compelling alternative for both mobile and stationary applications in construction machinery. Bosch Rexroth’s eLION portfolio, which includes motors, inverters, gearboxes, and integrated hydraulics, is expanding to incorporate components for 96-volt electrical systems, along with a new standardized software platform coming later in 2025. Meanwhile, Bosch Engineering is introducing a compact, high-performance electric powertrain system capable of handling up to 800 volts—ideal for machines like wheel loaders that require high power output but have limited installation space.

Bosch, Bosch Rexroth, and Bosch Engineering will be showcasing these cutting-edge powertrain solutions at bauma 2025 at booths A3/327 and A4/526.
