Making a splash at NACV

Drip. Drip. Drip. It may just be tiny droplets of water dribbling out of Cummins’ latest innovation, but it is making a big splash this week at the North American Commercial Vehicle Show (NACV) in Atlanta. Building upon a long history of innovation and delivering industry-leading solutions, Cummins is displaying the newest development in the powertrain of choice: hydrogen fuel cell power. 

Unveiling in a Big Way

After many months of behind the scenes work, which is really the culmination of more than 20 years of research and development around fuel cell technologies, Cummins has unveiled a heavy-duty truck with fuel cell and battery electric power. The zero-emissions class 8, 6x4 day cab tractor is a technology demonstrator suitable for vocational applications, including regional haul, urban delivery operations, port drayage and terminal container handling. 

Under the Hood

The truck was designed and integrated by Cummins in Columbus, Ind. and includes a proton exchange membrane (PEM) fuel cell from Hydrogenics, a recent addition to the Cummins family. The truck was designed for 90 kW fuel cell and is scalable in 30 kW or 45 kW increments up to 180 kW and has 100 kWh lithium-ion battery capacity. The truck has a range of 150-250 miles between filling up, but that range can be extended with additional hydrogen tanks, increasing the tank storage pressure or installing additional fuel cells to optimize management of the vehicle load factor.

Many of the critical components of the powertrain, including the PEM fuel cell, system controller, powertrain controls, wire harnesses and junction boxes, among others, were designed and developed by Cummins. Cummins has also integrated third party components into the system. 

The Look 

Some might be surprised by the overall look of the fuel cell truck – it doesn’t feature any Cummins red! Instead, the exterior truck branding prominently showcases water. The meaning behind this is twofold. First, when the fuel cell is running, the exhaust consists of air and water. Liquid water flows out from an outlet hose behind the side panels on the driver’s side. Second, hydrogen can be sourced from water using a process called electrolysis to produce electrical energy. The use of water, along with the Jeopardy-style answer of “Hydrogen is how.” to the question of “How does it work?” helps to distinguish the hydrogen fuel cell technology that is unique to the vehicle.

The second thing you’ll notice about the truck is the OEM, or more accurately the lack thereof. The truck was not a collaboration with an OEM partner and was deliberately designed to be OEM agnostic. The goal was to allow all OEMs customers and end users to envision how Cummins fuel cell power can enable their success. 

Without looking under the hood, the truck might look like any other truck, and in fact, the goal is to provide the same dependable performance as every other Cummins-powered truck. So, even though we never intend to manufacture the truck itself instead focusing on innovating the powertrain, having an OEM-neutral vehicle that showcases the art of the possible through a modern, innovative “package” is important to the overall positioning of the technology. 

The Team Behind the Innovation

To say this was a team effort would be an understatement. The truck was designed and built at the Cummins Machine Integration Center (CMIC) in Columbus. The facility supports global vehicle integration efforts for multiple business segments for on- and off-highway equipment and features a dedicated EV Lab for electrification work. More than 30 engineers and technicians, including a few from Hydrogenics who jumped in post-acquisition, and numerous suppliers had a hand in taking this from simply a concept, to a truck that could be driven onto the tradeshow floor.

The truck is a example of the collaboration between system engineering, technology leadership teams within Electrified Power and Cummins research and technology group and the technical operations team at CMIC which supports Cummins Southern Indiana fleet of 450 vehicles.

Looking to the Next 100 Years

Cummins’ strategy is to provide our customers with a range of power options, from advanced diesel and natural gas internal combustion engines to battery electric and hydrogen fuel cell solutions. In the long-run, the customers we serve will likely need more than one type of power, depending on their specific markets, applications and use cases. 

To this end, Cummins has made several recent announcements around fuel cells like the acquisition of Hydrogenics, a memo of understanding with Hyundai Motor Company to collaborate on hydrogen fuel cell technology across commercial markets in North America and an investment in Loop Energy, a fuel cell electric range extender provider. Developing the hydrogen fuel cell truck as technology demonstrator is a critical step in gaining valuable insights that are critical to continue developing the right solutions for the market and preparing for next 100 years. 

So, the next time you hear a drip or step in a puddle, take a minute to think about the possibilities.

Cummins celebrates first European Hydrogen Week with a look-back at hydrogen and fuel cell successes in Europe

Cummins celebrates first European Hydrogen Week with a look-back at hydrogen and fuel cell successes in Europe

Hydrogen will contribute significantly to the transition to clean technology in Europe, and across the world. In July, the European Commission announced its hydrogen strategy to explore the potential of clean hydrogen to help the process of decarbonising the EU economy in a cost-effective way, in line with the 2050 climate-neutrality goal, set out in the European Green Deal. To match the interest and importance of hydrogen and fuel cell technologies in the energy transition, this week the first European Hydrogen Week takes place. 

At Cummins, we are proud of our ability to innovate and scale hydrogen fuel cell technologies across a range of commercial markets. September marked the one-year anniversary of the acquisition of Hydrogenics, which expanded Cummins alternative power solutions to include fuel cell technologies and hydrogen production capabilities. In addition, just last week Cummins held its Hydrogen Day event, where it revealed the potential of a decarbonised future fuelled by hydrogen. As we look to the future, we see many new possibilities and opportunities to better serve our customers and our planet. 

To celebrate the first European Hydrogen Week, join us as we look-back at Cummins’ successes in fuel cell and hydrogen technologies in Europe.

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  

HyLYZER PEM ElectrolyzerCummins, 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.

Electrolyzers 101: What they are, how they work and where they fit in a green economy

Cummins electrolyzers - Hero image

As Cummins looks to the future, we see a shift in the energy market. With that change comes new possibilities and opportunities beyond our traditional product set. To better serve our customers and our planet, Cummins is innovating new, sustainable forms of power and bringing a wide range of new possibilities to the New Power product portfolio, providing a way to produce clean hydrogen to power hydrogen fuel cells, supply industrial processes or produce green chemicals like fertilizers, renewable natural gas and methanol. 

Cummins offers a variety of hydrogen-based technologies, including electrolyzer systems, and recently announced it will provide its 5-megawatt PEM electrolyzer to convert surplus hydro power to clean hydrogen for the Douglas County Public Utility District in Washington state (USA). But what exactly is an electrolyzer, how does it work and where does it fit in our green economy? 

What is an electrolyzer and how does it work?

Electrolysis - ElectrolyzerAn electrolyzer is a system that uses electricity to break water into hydrogen and oxygen in a process called electrolysis. Through electrolysis, the electrolyzer system creates hydrogen gas. The oxygen that’s left over is released into the atmosphere or can be captured or stored to supply other industrial processes or even medical gases in some cases.

The hydrogen gas can either be stored as a compressed gas or liquefied, and since hydrogen is an energy carrier it can be used to power any hydrogen fuel cell electric application — whether it’s trains, buses, trucks, or data centers. 

In its most basic form, an electrolyzer contains a cathode (negative charge), an anode (positive charge) and a membrane. The entire system also contains pumps, vents, storage tanks, a power supply, separator and other components. Water electrolysis is an electrochemical reaction which takes place within the cell stacks. Electricity is applied to the anode and cathode across the proton exchange membrane (PEM) and causes the water (H20) to split into its component molecules, hydrogen (H2) and oxygen (O2).

Are there different kinds of electrolyzers? 

Yes, they range in size and function. These electrolyzers can be scaled to meet a variety of input and output ranges, ranging in size from small industrial plants installed in shipping containers to large-scale centralized production facilities that can deliver the hydrogen by trucks or be connected to pipelines.

There are three main types of electrolyzers: proton echange membrane (PEM), alkaline and solid oxide. These different electrolyzers function in slightly different ways depending on the electrolyte material involved. Both alkaline and PEM electrolyzers can deliver on-site and on-demand hydrogen, pressurized hydrogen without a compressor and 99.999% pure, dry and carbon-free hydrogen.

The difference between the three main kinds of electrolyzers include:

Alkaline ElectrolyzerAlkaline Electrolyzers

  • Uses a liquid electrolyte solution such as potassium hydroxide (KOH) or sodium hydroxide (NAOH), and water. 
  • The hydrogen is produced in a “cell” which consists of an anode, cathode and membrane. The cells are typically assembled in series in a “cell stack” that produces more hydrogen and oxygen as the amount of cell increases. 
  • When current is applied on the cell stack, the hydroxide ions (OH-) move through the electrolyte from the cathode to the anode of each cell, with hydrogen gas bubbles generated on the cathode side of the electrolyzer and oxygen gas at the anode, as represented here.

 

Proton Exchange MembraneProton Exchange Membrane (PEM) Electrolyzers

  • PEM electrolyzers use a Proton Exchange Membrane which use a solid polymer electrolyte.
  • When current is applied on the cell stack, the water splits in hydrogen and oxygen and the hydrogen protons pass through the membrane to form H2 gas on the cathode side.

 

 

 

 

Solid Oxide ElectrolyzerSolid Oxide Electrolyzers (SOEC) 

  • Uses solid ceramic material as the electrolyte
  • Electrons from the external circuit combine with water at the cathode to form hydrogen gas and negatively charge ions. Oxygen then passes through the slid ceramic membrane and reacts at the anode to form oxygen gas and generate electrons for the external circuit
  • SOECs operate at a much higher temperature (above 500C) than alkaline and PEM electrolyzers (up to 80C) and have the potential to become much more efficient than PEM and alkaline.

 

How are electrolyzers commercialized based hydrogen production?

There are four main ways that electrolyzers can be commercialized:

  1. Power to mobility: Hydrogen can be used as fuel at refueling stations for fuel-cell electric vehicles such as buses, trains, and car.
  2. Power to Fuel: Be used in refineries to remove sulfur from fossil fuels. 
  3. Power to Industry: Be used directly as an industrial gas in the steel industry, flat glass plants, semi-conductor industry, etc.  It can also be injected directly into the natural gas grids for lower carbon heating and other natural gas applications.
  4. Power to Gas: Be used in the production of green chemicals such as methanol, fertilizers (ammonia) and any other liquid fuel, even jet fuel!  

Electrolyzer - Power to Industry

What’s so unique about hydrogen fuel cells?

The hydrogen produced from an electrolyzer is perfect for use with hydrogen fuel cells. Working much like a battery, fuel cells do not run down or need charging and produce electricity and heat as long as fuel is supplied. You can learn more about batteries and fuel cells here. The fuel cells use the hydrogen to generate electricity with zero emissions at the point of use. That means no fossil fuels or harmful emissions come from the tailpipe.

Even better, when the electrolyzer system is powered by a renewable energy source, such as a hydropower from the Columbia River Dams, the hydrogen produced is considered renewable and CO2-free from well to wheel. Learn more about well to wheel emissions in all-electric and fuel cell applications.

Why is hydrogen such a good option for clean energy?

Hydrogen presents an opportunity for mass market change in the energy industry. Energy systems across the globe are undergoing a fundamental transformation to focus on lower emissions and less negative impact on the environment.

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.

Hydrogen can act as an energy storage medium to address these grid challenges, allowing renewable power to be more easily used outside the electric power grid. Hydrogen is a stable way to store and transport renewable electricity efficiently over long periods of time. That way, renewable electricity generated by wind and solar that isn’t being used right away can be used another time or in another place. Hydrogen’s potential for storing and transporting energy makes it a key enabler of a global transition to renewable energy.

What is Cummins doing with electrolyzers?

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. Cummins continues to make quick progress in innovating new products and applications in the hydrogen space, and currently, there are two different types of electrolyzers offered by Cummins:

  1. The HyLYZER® Polymer Electrolyte Membrane (PEM) Electrolyzer uses an ionically conductive solid polymer and is better suited for large-scale hydrogen production.
  2. The HySTAT® Alkaline Electrolyzer uses a liquid electrolyte and is well-suited for small- to medium-scale hydrogen production.
