Can A Car Engine Run On Hydrogen? Exploring The Potential Fuel Revolution

Why isn’t hydrogen commonly used as a fuel source for engines? The answer lies in the inherent inefficiency, high maintenance costs, and environmental drawbacks associated with hydrogen combustion engines. As of February 20, 2022, it’s important to note that hydrogen combustion engines face several challenges that have limited their adoption compared to alternatives like fuel cells or battery powertrains. These challenges include lower efficiency, higher maintenance expenses, and a greater negative impact on the environment, making them less practical and sustainable choices for powering vehicles.

Can hydrogen be utilized as a viable fuel source for automobiles? Indeed, hydrogen can indeed be employed as fuel for internal combustion engines, although there are notable distinctions when compared to fuel cell electric vehicles (FCEVs). Unlike FCEVs, internal combustion engines powered by hydrogen do emit tailpipe emissions and tend to exhibit lower efficiency levels. To put this in perspective, the energy contained in 2.2 pounds (1 kilogram) of hydrogen gas is roughly equivalent to the energy found in 1 gallon (equivalent to 6.2 pounds or 2.8 kilograms) of gasoline. To delve further into the topic of hydrogen as a car fuel, it’s essential to explore the contrasting aspects of these technologies and their environmental impact.

The viability of hydrogen fuel as a sustainable energy source for the future is a topic of concern, and it’s crucial to examine the claims made by fossil fuel companies regarding its potential. These companies argue that they can repurpose existing pipelines for the transportation of “clean hydrogen” in the future. However, it’s essential to consider that hydrogen is both highly flammable and corrosive, which poses significant safety challenges when retrofitting oil and gas infrastructure for hydrogen transport. This retrofitting process would likely be expensive and complex. As of March 7, 2023, these concerns underscore the ongoing debate surrounding the practicality of hydrogen as a viable alternative in the energy transition.
