You must be wondering, what exactly is hydrogen fuel cell (HFC) technology, and what is so good about it?  Hydrogen fuel is a clean fuel that is burned along with oxygen in an electrochemical power generator to generate electricity, and in the process, produces water and heat as by-products. What sets hydrogen fuel apart, however, is the fact that it serves as an alternative to diesel fuel in more ways than one: its fuel-cycle emits no pollutive exhaust, and through renewable energy, there contains no trace of greenhouse gas emissions. Vehicles that are powered by the hydrogen fuel cell, thus, significantly reduce our use and dependence on diesel oil and lower the chances of harmful emissions contributing to climate change. What started out as an experiment among startup companies and early projects is now dominating the commercial vehicle industry with many of the industry’s biggest players putting in large investments in the technology. 

How Does it Work?

Hydrogen fuel can be produced through several methods, and in the commercial vehicle industry, fuel is processed in a fuel cell that is composed of three main components: an anode, a cathode, and an electrolyte membrane. This type of fuel cell is called a Proton-Exchange Membrane Fuel Cell, or also known as a polymer electrolyte membrane (PEM) fuel cell, which is mainly reserved for transport applications and stationary and portable fuel cell applications. The PEM fuel cell does its job by passing hydrogen through the anode, at which hydrogen molecules are split into electrons and protons. The former ones take the path of a circuit in the fuel cell to generate electric current and excess heat, while the protons go through the electrolyte membrane. At the same time, the PEM fuel cell passes oxygen from the surrounding air through the cathode on the other side, where the oxygen meets with the protons and electrons to produce water molecules. This does not get any simpler than your run-of-the-mill science experiment in school!

What Are Fuel Stacks Then?

What lies in the heart of a fuel cell vehicle (FCV) is the fuel cell stack. Because fuel cells generate less than 1.16 volts of electricity each, they must be assembled atop one another to create a fuel cell stack in order to generate enough power to run a vehicle. The potential power that can be generated by a fuel cell stack largely varies and is dependent on the number and the size of the individual fuel cells of the fuel cell stack, as well as the surface area of the PEM. 

The Preferred Alternative

Hydrogen fuel cell has been proven to yield positive results for both the environment and the wallet in the long term. 

Reduction in Greenhouse Gas Emissions

Contrary to diesel fuel, which emits greenhouse gases (GHGs) and carbon dioxide (CO2) that are large contributors to climate change, the only by-products of vehicles–when fueled by pure hydrogen–are heat and water with the release of zero tailpipe GHGs. While it is possible for FCVs to still generate GHGs, depending on the production method, the GHGs emitted is still far less great than those emitted by gasoline and diesel fuel. FCVs also eliminate the maintenance costs that come with storing diesel fuel that may prove harmful later on. Many of the industry’s big players make use of environmentally benign hydrogen in their hydrogen fuel cell products to eliminate and prevent the harmful impact of fuel spillage or leaks and air pollution. 

Cutback on Vehicle Oil Dependence

Many companies have incorporated hydrogen fuel cells in their corporate sustainability programmes, and the industry is seeing a shift of focus from diesel fuel to environmentally friendly alternatives. With the industry soon to be saturated with FCVs, our dependence on foreign oil will be significantly reduced and eventually eradicated. Hydrogen can be extracted sustainably from domestic sources, such as natural gas and coal, as well as from renewable sources, such as water, biogas, and agricultural waste. From an economic perspective, this would allow us to be less affected by oil price hikes and drops in the volatile oil market. 

Lowering of Operational Costs

Hydrogen fuel cells require little to no maintenance as they eliminate the need to change, charge, and manage batteries, a maintenance check that is necessary for batteries, internal combustion generators, and the like. Hydrogen fuel cell units have a longer running time than do lead-acid batteries and, when power is running low, would not take more than five minutes to refuel. Companies that employ FCVs in their fleet benefit substantially from this as it reduces vehicle and personnel time, giving birth to a higher efficiency rate. This loss of regular maintenance saves not only money but labour, time, and the space for battery rooms as maintenance checks require optimal conditions. 

Increase in Energy Efficiency

 Hydrogen fuel cells are well known to be more energy-efficient than other forms of power. When a fuel cell vehicle is fueled by pure hydrogen, the hydrogen fuel cell has the potential to be up to 80-percent efficient. This means that the fuel cell converts up to 80 percent of the energy content of the hydrogen into electrical energy. The electric motor and inverter of the vehicle thus have the responsibility to convert that electrical energy into mechanical energy, with an average of 80 percent efficiency. Combined, this gives an overall 64-percent of increased efficiency when a vehicle is powered by a hydrogen fuel cell!

Increase in Durability and Reliability

Hydrogen fuel cells are notably more robust than other forms of fuel and can weather all types of conditions, from cold environments to harsh storms. This makes fuel cells a reliable asset to companies that engage commercial vehicles in tough environments. Additionally, because they do not have any moving parts, hydrogen fuel cells operate quietly even in the midst of a snowstorm! 

With environmentally friendly applications and time-consuming maintenance, we are beginning to see the boom of hydrogen fuel cell technology in the commercial vehicle industry, and with good reason! (MT)

Horse Powertrain, a leading supplier of powertrain solutions, has launched the V20 engine through its Aurobay Technologies division with production already underway at its Skovde, Sweden, manufacturing facility.

The V20 engine aims to assist automakers in meeting emission regulations for 2026 and 2027 with units destined for customers in Europe, the US and Asia. The 2.0-litre, 4-cylinder engine features a single architecture offered in two variants: a 400-volt plug-in hybrid and a 48-volt mild hybrid. The plug-in version provides a reduction in fuel consumption of seven per cent compared to the predecessor.

The platform design intends to reduce material costs. Hardware for the plug-in variant includes a crankshaft-mounted starter-generator, a mechanical water pump, and a re-routed cooling system. Additional updates include a multi-injection fuel system, an engine management system, and an air induction system.

Ingo Scholten, Managing Director, Aurobay Technologies Sweden and Deputy CTO of Horse Powertrain, said, “Designing one engine to meet three different regulatory regimes is harder than designing three separate engines. As the regulatory map is fragmenting, one engine that meets all three sets of rules delivers greater value to our customers, ensuring we can offer greater economies of scale. Pulling that off requires serious engineering. Further, the Skovde team also successfully changed production lines while keeping current production running.”

The Skovde plant integrated a final assembly line with the base assembly line to improve material flow. This transition occurred during ongoing operations. Output is scheduled to increase through 2026 and 2027 to meet demand.
