Cummis highlights hydrogen engine at Agritechnica 2023

Cummins presents its B6.7H hydrogen engine at Agritechnica 2023 in Germany ("Cummins B6.7H hydrogen engine"). Intended for tractors and agricultural machinery, it has a maximum power of 294 hp (290 hp) and a maximum torque of 1.200 Nm.

According to the company, this is an entirely new engine platform with technology to increase power density, reduce friction losses and improve thermal efficiency. As a result, "performance is equivalent to that of a diesel engine of similar displacement and compatible with the same transmissions, drivetrains and cooling packages." Another benefit of the B6.7H is that it runs significantly quieter than a diesel.

The engine can be installed in the same equipment as a diesel engine. Maintenance practices and costs are also comparable to diesel engines, the company reports. The main difference to consider is the fuel system.

Onboard storage is a critical component. The hydrogen needs to be compressed into the available space to store enough to meet the vehicle's duty cycle requirements. Cummins has a joint venture with NPROXX, specializing in the subject. The designed storage tanks will have a pressure capacity of up to 700 bar to maximize capacity and operational range.

“Cummins has been developing leading power solutions for over a hundred years, and we continue to demonstrate our leadership in developing a wide range of future-oriented, sustainable transmissions – with hydrogen playing a key role,” said Antonio Leitão, vice president off -road from Cummins. Engine business. “Our strategy is to focus on the entire hydrogen value chain to drive sustainability and enable faster adoption.”

Following recent acquisitions and investments, Cummins' focus is on three key areas for hydrogen: green hydrogen production, hydrogen management and transportation, and the application of hydrogen in engines and fuel cells.
