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)

India’s automotive industry could face fresh supply chain disruptions by mid-July 2025 due to declining inventories of rare earth magnets, following tightened export restrictions and shipment delays from China, according to rating agency ICRA.

Jitin Makkar, Senior Vice President and Group Head – Corporate Ratings at ICRA, cautioned that the situation echoes the semiconductor shortage of 2021–22, which led to the loss of nearly 100,000 passenger vehicles. “Rare earth magnet inventories are projected to last only until mid-July 2025 for several passenger vehicle and two-wheeler applications,” he said.

Neodymium-iron-boron (NdFeB) magnets, critical for high-performance uses like EV traction motors and power steering systems, are heavily imported – around 85 percent of India’s USD 200 million imports in FY2025 came from China. These magnets make up nearly 30 percent of an electric two-wheeler motor’s cost, with motors priced between INR 8,000 and INR 15,000 depending on specifications.

To counter the supply challenge, Indian OEMs and auto component manufacturers are exploring several alternatives: importing fully assembled motors from China, sending rotors to China for magnet assembly, using substitute materials with similar properties, or switching to rare earth-free motors using electromagnets. However, each option faces significant logistical, regulatory, and engineering hurdles.

While the immediate impact could disrupt production planning, ICRA believes the crisis may also drive innovation and diversification in both materials and supply chains for the Indian auto sector.

Hyundai Mobis, a part of Hyundai Group specialising in manufacturing of auto components, modules & systems, has developed a new rear safety control technology that can reduce rear-end collisions.

The company states its new active control technology uses sensors to detect approaching vehicles from behind and manoeuvre the vehicle out of danger, is expected to hit the market soon. It integrates sensors such as rear-side radars and front cameras with driving control technology.

The solution works when the driver engages the Smart Cruise Control (SCC) function on the highway. When the sensors detect any other vehicle at a proximity of 10 metres or less, it first emits an audio alarm or a visual warning on the cluster. When the situation keeps persisting after a certain amount of time, the vehicle automatically accelerates to maintain a safe distance. In addition, the rear side radars also detect the movement of the vehicle behind, while the front camera recognises the lane and vehicle ahead on the driving path to assist in safe acceleration.

Hyundai Mobis acknowledges that while some global OEMs have already integrated such technology, the functions are not yet advanced enough for the vehicle to control itself autonomously. On the other hand, its technology is able to independently adjust the distance between the front and rear vehicles and avoid dangerous situations.
The Korean company plans to further expand the scope of autonomous control for defensive driving against rear vehicles. Currently, the company is developing a lane-changing function to escape dangerous situations, in addition to an acceleration control function that allows the vehicle to speed up on its own.

Jung Soo-kyung, Executive Vice-President and Head of Automotive Electronics Business Units, Hyundai Mobis, said, “We will actively protect the safety of mobility users by providing solutions that can intelligently handle not only front-end safety, but also dangerous situations caused by rear vehicles while driving.”

Chinese-owned Swedish automotive major Volvo Cars has unveiled a new multi-adaptive safety belt, which it claims is a world-first technology aimed to further enhance safety for everyone in real-world traffic situations. The multi-adaptive safety belt is set to debut in Volvo EX60 in 2026, the company’s fully electric offering. It uses real-time data from the cars advanced sensors to adapt to traffic variations and the user wearing the seatbelt.

Based on the data input from interior and exterior sensors the seatbelt provides customised protection, adapting the setting based on the situation and individual’s profiles, such as their height, weight, body shape and seating position. For example, a larger occupant in a serious crash will receive a higher belt load setting to help reduce the risk of head injury. While a smaller occupant in a milder crash will receive a lower belt load setting to reduce the risk of rib fractures. Using over-the-air software updates, it gets better over time.

Asa Haglund, Head of Volvo Cars Safety Centre, said, “The world's first multi-adaptive safety belt is another milestone for automotive safety and a great example of how we leverage real-time data with the ambition to help save millions of more lives. This marks a major upgrade to the modern three-point safety belt, a Volvo invention introduced in 1959, estimated to have saved over a million lives.”

The Swedish carmaker stated that modern safety belts use load limiters to control how much force the safety belt applies on the human body during a crash. This new safety belt expands the load-limiting profiles from three to 11 and increases the possible number of settings, enabling it to optimise performance for each situation and individual. Unlike traditional systems, the new multi-adaptive safety belt can utilise data from different sensors, including exterior, interior and crash sensors. In less than a blink of an eye, the car’s system analyses the unique characteristics of a crash – such as direction, speed and passenger posture – and shares that information with the safety belt. Based on this data, the system selects the most appropriate setting.
