Three Cummins hydrogen production facilities that are helping build a green economy

Hydrogen elctrolyzer

To decrease the negative impacts of climate change and decarbonize the power sector, renewable technologies like wind and solar have emerged as key ingredients to providing a solution. But integrating these intermittent energy sources into the power grid can be challenging. This is where electrolyzers come. Hydrogen makes other forms of renewable energy more viable by providing efficient and portable storage of electricity. Electrolyzers enable the production of hydrogen, which can be used by industrial clients or stored and used to power applications, including trains, buses, trucks and more, and Cummins has hundreds operational in the field.  

Take wind turbines as an example. Electrolyzers can economically convert wind energy to hydrogen and oxygen in a process called water electrolysis. Water electrolysis produces no harmful emissions — only oxygen and hydrogen. Hydrogen is produced when electricity prices are low which is typically the case when wind energy is abundant. Then, the hydrogen can be stored or transported  to customers. Hydrogen’s potential for storing and transporting energy makes it a key enabler of a global transition to renewable energy. 

Cummins made a bold entry into the hydrogen economy in September 2019 with the acquisition of Hydrogenics, a global hydrogen fuel cells and electrolyzer technology manufacturer, and Cummins continues to make quick progress in innovating new products and applications in the hydrogen space, including three electrolyzers that are making an impact:  

HyBalance – Denmark: Supplying clean hydrogen to 1,000 fuel cell vehicles  HyBalance

Cummins, along with its partners, established this 1.2-megawatt proton exchange membrane (PEM) electrolyzer site more than two years ago in Denmark. The site supplies clean hydrogen to customers of Air Liquide, a world leader in gases, technologies and services for Industry and Health, with Air Liquide operating the site. The PEM electrolyzer in Denmark is capable of supplying a fleet of more than 100 fuel cell electric vehicles per day and could contribute up to 0.5 percent of the transport sector greenhouse gas reduction targets in Denmark. 

Douglas County – U.S.A.: Enabling utilities to store excess energy 

Expected to be operational in 2021, this 5-megawatt PEM electrolyzer located in Douglas County in Washington state (U.S.A) will be the largest, as well as first of its kind in use by a public utility, in the United States. The new renewable hydrogen facility allows the Douglas County Public Utility District (PUD) to manufacture commercial hydrogen using electrolysis to harvest hydrogen from water from Wells Dam on the Columbia River. Cummins’ PEM electrolyzers, like Douglas County PUD’s electrolyzer, enables utilities to store the excess energy that they would typically sell off to the market at a financial loss, or not harness at all, and instead store that energy to sell into a new green hydrogen market. Additionally, it creates a way for utilities to engage in new market opportunities outside of their typical service area, removing growth barriers often faced in the industry. This project is made possible by legislation passed in Washington state in 2019, which authorized public utility districts to make and sell hydrogen. 

Becancour – Canada: Building the largest PEM electrolysis plant in the world 

Cummins is in the final stages of commissioning the largest PEM electrolysis plant in the world in Becancour, Canada for Air Liquide. The 20-megawatt facility will have an annual hydrogen output of approximately 3,000 tons. The electrolyzer will use renewable hydroelectricity to generate decarbonized, and green, hydrogen. The facility is planned to be operational in the coming months.

Cummins New Power President emphasizes decarbonizing now at The New York Times Climate Hub

Cummins New Power President emphasizes decarbonizing now at The New York Times Climate Hub

Amy Davis, Vice President and President of New Power, painted a picture of a decarbonized transportation sector with the help of both battery electric and hydrogen-powered solutions at The New York Times Climate Hub in Glasgow, Scotland, earlier this month. And while the debate between various low- and zero-carbon solutions continues around the world, she urged governments and corporations to start doing something now – because the carbon you put out today, tomorrow and next week cannot be taken back.

Cummins is over 100 years old, and we’ve been powering all kinds of commercial applications. One of the things we know is that [transportation] is very diverse, and we believe it’s not going to take just one solution [to decarbonize it].” – Amy Davis, President of New Power

In parallel with the 2021 United Nations Climate Change Conference, COP26, the Climate Hub hosted its program The Forum.  Over nine days, people across the globe tuned in to 45 live discussions, debates and workshops that addressed the mounting threat of climate change and what actions can be taken to stop it. 

Davis’ presence at The Forum was just one of numerous engagements and initiatives occurring in Glasgow that week. Cummins Chairman and CEO Tom Linebarger also attended COP26, meeting with governments, industry leaders and media to advocate for the shift from fossil fuels to low- and no-carbon solutions and demonstrating how Cummins will be part of the energy transition.

In the days leading to COP26 and The Forum, Cummins was accepted into two influential groups advocating for climate action

The consensus across conversations was that moving toward a carbon-free world is essential – but is it easier said than done? How do we make decarbonization happen? What does decarbonization even look like?

During the Transport and Mobility panel Time and Space: Moving People and Goods in a Carbon-Free World, Davis participated alongside Avinash Rugoobur, President of Arrival; Laura Lane, Chief Corporate Affairs Officer of UPS; and Peter Vanacker, President and CEO of Neste – all transportation and technology companies moving the industry toward a cleaner, greener future.

Watch the full discussion below as The New York Times climate reporter and panel moderator Brad Plumer opens the floor to Davis to discuss why Cummins is approaching decarbonization beyond just electrification, how infrastructure challenges have influenced hydrogen in mobility, and how transitionary periods lead to innovation in aftermarket solutions.

What is a fuel cell?

Fuel cells are a key technology to unlocking our carbon-neutral future

Fuel cells aren’t new. In fact, the first reference to hydrogen fuel cells appears in 1838 in the December issue of The London and Edinburgh Philosophical Magazine and Journal of Science. Almost 200 years later, the world is recognizing fuel cells as a key technology to unlocking a carbon-neutral future.

Here is what they are, how they work and two fuel cell types that Cummins is investing in.

What is a fuel cell in simple terms?

Like batteries, fuel cells are energy converters – they use an electrochemical reaction to take the chemical energy stored in a fuel source and convert it to electricity. Unlike batteries, which contain a fixed supply of energy, fuel cells do not require recharging. As long as fuel is continuously supplied to the fuel cell, electricity, water and heat will be produced.

How does a fuel cell work?

A fuel cell is comprised of two electrodes and an electrolyte membrane. The electrodes are called a cathode and an anode, and they sandwich the electrolyte membrane between them. Within that system, a series of chemical reactions occur to separate the electrons from the fuel molecules to create energy.

The fuel, typically hydrogen, is fed into the anode on one side while oxygen is fed into the cathode on the other. At the anode, the hydrogen fuel molecules are separated into protons and electrons that will travel different paths toward the cathode. The electrons go through the electrical circuit, creating the flow of electricity. The protons travel through the electrolyte to the cathode. Once at the cathode, oxygen molecules react with the electrons and with the protons to create water molecules.

A fuel cell is a clean energy source with the only byproducts being electricity (power), heat and water. A single fuel cell alone only produces a few watts of power; therefore, several fuel cells can be stacked together to create a fuel cell stack. When combined in stacks, the fuel cells’ output can vary greatly, from just a few kilowatts of power to multi-megawatt installations.

What fuels can be used in fuel cells?

Fuel cells offer flexibility in the fuel type that can be used. While hydrogen is the most common fuel source for fuel cells (hence the common name, hydrogen fuel cells), hydrogen-rich fuels such as natural gas and ammonia are also viable fuel sources.

Hydrogen: When produced using renewable electricity – like solar, wind and hydropower – hydrogen is completely decarbonized and produces zero emissions. Hydrogen fuel cells (i.e. fuel cells that are fueled by hydrogen) produce power, heat and water and release no carbon dioxide or other pollutants into the air.

Natural gas: As widespread production of green hydrogen is still in progress, natural gas is currently the most-used fuel to power fuel cells. In this case the fuel cells are not completely emission-free, but they do offer significantly lower emissions than other fuels, like oil and coal.

Ammonia: Ammonia is most used in agriculture as fertilizer. However, in recent years, several companies have been working to develop green ammonia. Green ammonia is made with hydrogen that comes from water electrolysis powered by alternative energy, making it another option for a low-carbon fuel.

What types of fuel cells is Cummins investing in?

There are six types of fuel cells that are under development, each primarily classified by the kind of electrolyte they employ. Each type of fuel cell has its own advantages, limitations and potential applications. Out of the six, Cummins has recognized the potential in two types of fuel cells – proton exchange membrane fuel cells and solid oxide fuel cells - and has invested in the advancement of their technologies and their application.

Proton exchange membrane (PEM) fuel cells: Also referred to as polymer electrolyte membrane fuel cells, this type of fuel cell uses a polymer electrolyte and operates at lower temperatures of around 80 degrees Celsius. PEM fuel cells are more suitable for mobile and back-up power applications due to their high-power density and quick start-stop capabilities.

Solid oxide fuel cells (SOFCs): SOFCs use a hard, non-porous ceramic compound as their electrolyte and operate at high temperatures, as high as 1,000 degrees Celsius.  This type of fuel cell is most suitable for stationary applications because it is highly efficient and fuel flexible. In addition, waste heat may be harnessed and reused to increase the overall system efficiency.

Why invest in fuel cells?

Already leaders in PEM electrolyzers that produce green hydrogen through electrolysis, we are working on making green hydrogen more readily available for future use in fuel cells. Cummins was awarded a U.S. Department of Energy grant for the advancement of SOFCs and have seen our fuel cells successfully support the operation of battery electric vehicles.

Fuel cells may predate the beginning of Cummins, but we are wasting no time discovering how to advance their technology to create a zero-emission future.

Video Case Study: Cummins HyLYZER® PEM electrolyzer in Bécancour, Quebec

The Cummins HyLYZER in Bécancour, Quebec, Canada, is the largest proton exchange membrane (PEM) electrolyzer in operation in the world. A new video case study highlights the installation’s ground-breaking green hydrogen production capabilities, making it a beacon for a zero-carbon future.

Watch below: 

Commissioned in January and installed at the Air Liquide hydrogen production facility in Quebec, this 20-MW electrolyzer system features industry-leading technology, including four compact, pressurized HyLYZER electrolyzer skids fitted inside the existing building. The systems are modular and scalable, perfect for large-scale utility applications.

Through a phased ramp up, the Cummins HyLYZER system is now at full operation and can produce up to 8.2 tons of low-carbon hydrogen per day — or nearly 3,000 tons of hydrogen annually. It’s powered by the region’s electric grid, which is largely supplied by renewable hydro-electric power. This means the hydrogen produced at the plant is “green” and almost entirely carbon-free.

Through this green hydrogen production, the facility is preventing approximately 27,000 tons of CO2 emissions per year. This is equivalent to taking 10,000 fossil-fueled cars off the road.

Since its commissioning, the system in Bécancour has increased Air Liquide’s hydrogen production capacity by 50%, allowing them to respond to the growing demand for low-carbon fuel in the North American market for both industrial and mobility purposes.
