Hydrogen technology by Cummins
By investing in innovative hydrogen solutions, we’re paving the road to clean power that helps you meet regulations, reduce emissions, and futureproof your business.
Why hydrogen fuel is the future of clean energy
As one of the most abundant elements in the universe, hydrogen is an essential part of how companies can meet their decarbonization goals and reduce their environmental impact.
No direct CO2 emissions
Hydrogen power reduces greenhouse gas emissions through fuel cells, which convert hydrogen to electricity, to power vehicles while releasing nearly trace amounts of carbon dioxide.
Renewable and readily available
Hydrogen is a renewable source that can be readily produced from water using renewable electricity. It burns without emitting greenhouse gases.
Long-term storage
Storing hydrogen onboard motor vehicles is safe, and with a storage pressure of 700bar, it enables more onboard fuel storage and an extended range.
Quick refueling capabilities
Hydrogen engines offer quick refueling times and diesel-like performance, durability, and reliability. Unlike electric vehicles, hydrogen vehicles do not need extra time to charge.
Explore resources for understanding hydrogen gas as a fuel
Hydrogen gas is a sustainable fuel option that’s accessible and adaptable. Our hydrogen gas solutions are paving the way for the fuel of the future.
Benefits of hydrogen for off-highway applications
A hydrogen internal combustion engine (ICE) can operate in the same locations as a diesel engine to benefit a wide range of industries.
Comparing hydrogen engines and fuel cells
While both hydrogen engines and fuel cells use hydrogen to power vehicles, fuel cells generate electricity from hydrogen.

Four-stroke Hydrogen combustion engines (H2ICE) operate on the same principles as traditional engines but are more powerful and efficient. They share components like engine blocks, cranks, and ignition systems with natural gas engines and seamlessly fit into existing designs. This article delves into the role of turbochargers in enhancing the performance and viability of hydrogen engines, showcasi
Knowing the fuel used for hydrogen fuel cells and hydrogen internal combustion engines (H2-ICE) is just as important as knowing the powertrains themselves. Fuel can impact not only performance but also a fleet’s green profile. Several terms are used to identify hydrogen and for various reasons. Different agencies, industries and entities involved in the use and production of hydroge
As the transportation industry shifts towards sustainable operations, a strong, reliable and extensive service network is essential for keeping vehicles on the road and fleets operating at peak performance. Service networks help fleets stay on the road faster and increase uptime (amount of time that a vehicle is available and operational for use) while also integrating advanced telematics and pred
Roughly three years ago there was not much talk about hydrogen engines according to Jim Nebergall, Executive Director – Market Strategy, Cummins Inc. “When I started, nobody knew what this was,” said Nebergall who also serves as Cummins’ general manager of hydrogen engines. “We decided this is important enough for Cummins to focus on.” The Biden administration, the European Union and t
In today's market, remanufacturing of engine parts is gaining traction as an eco-friendly and economically viable option. Remanufacturing extends the lifecycle of an engine, ensuring both environmental sustainability and cost-effectiveness. This article looks at how Cummins Inc. uses remanufacturing for its ReCon® remanufactured parts and engines. What is remanufacturing? ReCon parts
What is the fuel delivery system? The fuel delivery system is one of the most critical components in a vehicle and is the heart of a vehicle's power generation process. The fuel delivery system serves a similar function to a fuel tank in diesel-powered vehicles. However, the fuel delivery system is specifically designed to handle gaseous fuels like hydrogen and natural gas, both of which are
FAQs about hydrogen gas fuel
Hydrogen fuel cells generate electricity through an electrochemical reaction where hydrogen and oxygen combine to produce electricity, water, and heat. They power vehicles using hydrogen, a zero-carbon fuel, by supplying electricity to an electric motor. Fuel cell hydrogen vehicles (FCEVs) are efficient for lower loads or operating without a load.
Hydrogen is easily produced from water using renewable electricity through a process called electrolysis. In this highly efficient electrochemical reaction that takes place in our electrolyzer system, water converts into hydrogen and generates hydrogen gas. This process emits no greenhouse gases and is both colorless and odorless.
Green hydrogen is produced using renewable energy sources like solar, wind, and hydropower to electrolyze water. The resulting reaction produces only hydrogen and oxygen, meaning the process doesn’t emit any carbon dioxide. Green hydrogen is the only color in the hydrogen rainbow that produces zero harmful greenhouse gas emissions.
Hydrogen engines are internal combustion engines that burn hydrogen as fuel. They are as reliable and durable as diesel engines and have many of the same components such as an engine block, crank, and installation parts. Hydrogen engines also look, sound, and work like internal combustion engines.
Hydrogen can be delivered or produced on-site. A hydrogen fueling station allows vehicles using a gaseous or liquid delivery model to refuel. Unlike electric vehicles, which can take a long time to fuel, hydrogen engines offer quick refueling times and diesel-like performance, durability, and reliability.
