In the quest for sustainable mobility solutions, hydrogen technology stands out as a promising contender. Hydrogen fuel cells, which convert hydrogen gas into electricity, offer a clean and efficient way to power vehicles. Despite its potential to revolutionize green transportation, hydrogen technology faces significant concerns.
The Promise of Hydrogen Technology
Hydrogen fuel cell vehicles (FCVs) produce zero emissions at the tailpipe, emitting only water vapor. This makes them an attractive alternative to conventional internal combustion engines and even battery electric vehicles (BEVs) in terms of environmental impact. Hydrogen is the most abundant element in the universe, and when produced from renewable sources, it can significantly reduce our reliance on fossil fuels.
Hydrogen fuel cells are also notable for their efficiency and performance. They can achieve higher energy densities than batteries, offering longer driving ranges and faster refueling times, similar to conventional gasoline vehicles. This makes FCVs particularly appealing for heavy-duty applications, such as trucks and buses, where battery weight and charging time are significant concerns.
Overcoming the Challenges with a Holistic Approach
One company making significant strides in overcoming these obstacles is HYVIA, a pioneer in green hydrogen mobility. We were fortunate to have them participate in our ZIW event in Paris this year, where their CEO, Nicolas Champetier, delivered a keynote on the challenges of hydrogen mobility.
Created in June 2021, HYVIA is a joint venture equally owned by Renault Group, a major player in the automotive industry, and Plug Power, a pioneer and world leader in turnkey hydrogen and fuel cell solutions. Their holistic offering includes solutions for vehicles, charging stations and financing & services.
“In a Hydrogen industry that is still in its infancy, we are mobilized to move gradually from a pioneering offering dedicated to hydrogen mobility in light commercial vehicles, to a mass production offering at the top end of the market, backed by a unique and comprehensive H2 ecosystem.” says Nicolas Champetier.

The Concerns Surrounding Hydrogen Technology
Despite these advantages, several concerns have slowed the widespread adoption of hydrogen technology. These concerns revolve around production, infrastructure, safety, and cost.
1. Production Challenges
One of the major concerns is the production of hydrogen. Hydrogen production is categorized by different colors based on the method of production, reflecting its environmental impact and energy sources.
Pink hydrogen is produced using nuclear power, leveraging the heat and electricity from nuclear reactors to split water molecules. Turquoise hydrogen is created through methane pyrolysis, a process that splits methane into hydrogen and solid carbon, with the potential for lower emissions if the carbon is captured. Blue hydrogen is generated via steam methane reforming. Finally, green hydrogen is produced using renewable energy sources, such as wind, solar, or hydroelectric power, to electrolyze water, resulting in a clean and sustainable hydrogen supply with minimal environmental impact.
Currently, most hydrogen is “blue”, since it’s produced from natural gas through SMR, which emits significant amounts of CO2. This undermines the environmental benefits of hydrogen FCVs.
While green hydrogen produced through electrolysis offers a cleaner alternative, it requires significant amounts of renewable energy. Scaling up this technology to meet global demand is a major challenge.
2. The Chicken and the Egg of Infrastructure
The lack of refueling infrastructure is another major obstacle. Building a hydrogen refueling network from scratch is costly and time-consuming. Compared to the well-established network of gasoline stations and the growing number of electric vehicle charging stations, hydrogen stations are few and far between. This creates a “chicken and egg” problem: consumers are reluctant to buy hydrogen vehicles without a robust refueling network, and investors are reluctant to build the infrastructure without a significant number of vehicles on the road.
3. Safety Concerns
Hydrogen is a highly flammable gas, and concerns about its safety have been a major deterrent. High-profile incidents involving hydrogen, while rare, have heightened public fears. However, it is important to note that hydrogen has been used safely in industrial applications for decades. Advances in storage and handling technologies, along with stringent safety standards, are mitigating these risks.
4. High Costs
The high costs of hydrogen production, fuel cell manufacturing, and infrastructure development are significant hurdles. While costs are expected to decrease with technological advances and economies of scale, they remain a major concern for the time being. Consumers and manufacturers alike are wary of the financial investment required to transition to hydrogen-based mobility.
Conclusion
Hydrogen technology holds great promise for sustainable mobility, offering zero-emission fuel cell vehicles (FCVs) and the potential for renewable hydrogen production. However, significant challenges must be overcome, including production methods, infrastructure development, safety concerns, and high costs.
Companies like HYVIA are making strides in addressing these issues by developing comprehensive solutions for vehicles and refueling stations. Their efforts demonstrate the importance of a holistic approach to advancing hydrogen mobility.
For hydrogen to become a mainstream solution, collaborative efforts from governments, businesses, and consumers are essential. With continued investment and technological advancements, hydrogen can significantly contribute to a cleaner, more sustainable future in transportation.
