Debunking Myths: The Reality of Electric and Hydrogen Buses Performance
Whenever I share articles about electric buses, enthusiasts for hydrogen technology quickly point out that diesel heaters are commonly utilized in western buses during colder months. They present this idea as if the waste heat generated by fuel cells is an effortless bonus, along with a misunderstanding of physical principles that necessitate diesel heating systems. This notion is often framed as a powerful argument.
This perspective certainly elicits strong emotions since it sounds impractical and counterintuitive; however, it is built on fundamentally flawed data and assumptions.
The Debate Between Hydrogen and Battery Electric Buses
The primary claim supporting hydrogen buses over battery electric models is their supposed ability to eliminate the need for additional heat sources, thus maintaining their range in winter conditions. Nevertheless, real-world evidence regarding fuel cell vehicles indicates significant range reductions during colder seasons.
For instance, hydrogen cars operating in Quebec demonstrated drops in fuel efficiency comparable to battery-operated vehicles during winter months; even traditional combustion engines suffer from similar rate declines when temperatures drop.
The Efficiency of Fuel Cells Explained
Now let’s revisit the claim about hydrogen-powered buses being exempt from using heaters—the underlying reason is quite straightforward: fuel cells are not highly efficient systems. They only manage to convert around 40% to 60% of the energy available in hydrogen into usable electricity while discarding the rest as waste heat. It’s essential to remember that all purchased hydrogen has a cost associated with it—especially green hydrogen—which tends to be pricier.
Utilizing waste heat can help mitigate some inefficiencies within the broader energy supply chain surrounding green hydrogen; however, likening this approach to burning premium whiskey for home heating doesn’t represent sound economics at all.
Batteries vs Hydrogen: A Closer Look at Current Practices
A notable issue among western bus manufacturers lies in their inadequate strategies surrounding bus heating systems which have traditionally revolved around repurposing excess heat generated by diesel engines into passenger compartments—an approach they’ve failed to optimize effectively over time with battery electric models relying instead on inefficient coil heaters.
This misalignment has fostered lower-performing electric options compared with their Chinese counterparts where innovators focus heavily on enhancing performance rather than investing resources into questionable concepts such as hydrogen buses—a pursuit that ultimately leads them away from achieving excellence.
Consequently, Western brands’ offerings fall short both range-wise and price-wise when contrasted against superior alternatives produced throughout China—where remarkable progress has been achieved via deliveries injecting approximately 44k units annually versus Europe’s total closer at ~5k last year spread amongst various vendors amidst lobbying efforts pushing for preferential treatment towards local products.
In fact Europe ranks second globally buying seven times more than North America presently producing only ~5k units.

A Global Perspective on Production Rates
If we consider China again—we observe approximately 700k operational battery electric units alongside roughly 5.3k existing fleets dedicated solely towards harnessing limited potential found within therein hyped-up ‘hydrogen’ solutions! In cities like Foshan where poor decision-making favored placing bets ranging alongside fueling strategies unlikely yield desired outcomes earlier realized elsewhere globally through effective methodologies immediately priorly formulated patterns reflect how one ought produce batteries while ridings towards elevated status amongst other creators!

The climatic diversity between regions also exemplifies why innovative manufacturers succeed better due increasing adaptive strategies developed capable managing frigid scenarios necessary especially competitive places sharing climate similarities previously cited above.
