Liebherr's hydrogen-fueled excavator wins Bauma award

2022 Bauma The Innovation Award is awarded to the company. R 9XX H2 Hydrogen Excavator

With a working weight of 50 tons Liebherr R 9XX H2 Suitable for extreme temperatures at construction sites、Use under impact and high dust conditions，The future may provide powerful solutions for earthworks and quarrying applications。

Liebherr said，Due to its commitment to alternative drive solutions，It takes a technology-neutral approach.。The hydrogen internal combustion engine is a technology the group is exploring.，Now the company's first hydrogen-powered crawler Excavator R 9XX H2 obtained Bauma Innovation Award。

The prototype is based in Colmar, France. Liebherr-France SAS Development。The machine is manufactured by the Liebherr Group's Engine Technology Centre in Switzerland. Liebherr Machines Bulle SA Produced H966 powered by hydrogen internal combustion engine。

With a working weight of 50 tons R 9XX H2 Suitable for extreme temperatures at construction sites、Use under impact and high dust conditions，Future solutions for earthworks and quarrying applications。

R 9XX H2 by Liebherr H966 powered by hydrogen internal combustion engine。The engine has six cylinders and uses port fuel injection (PFI)，Its Liebherr uses direct injection in its hydrogen engines. (DI)。It is reported that，Liebherr's component products division plans to start mass production of hydrogen engines by 2025.。
At“Tank to wheel”On the basis of，I.e., when used on a construction site，The company says hydrogen Excavators emit almost no carbon dioxide.。From cradle to grave——Or from production to decommissioning——CO2 emissions are 70% lower than comparable conventional powered excavators%。

24-30 October，Visitors to the BMW show in Munich, Germany, can experience Liebherr R9XX H2 Hydrogen excavator。The excavator was part of a machine display at the Liebherr booth in the outdoor area.，The company demonstrated a variety of machines and prototypes with alternative drive systems.。

The booth offers a combination of HHands-on experience with the second prototype of the 966 hydrogen internal combustion engine。It can be found in the Innovation Lab.，This is an exhibition area dedicated to Liebherr's alternative drive concept approach.。

At AHall 4 Liebherr Components Another prototype four-cylinder hydrogen engine can be seen on stand 326.，That is, direct injection is used (DI) Yes H964。
