Toyota CEO Akio Toyoda has expressed misgivings about electric automobiles, emphasizing the need for hydrogen-powered technology in vehicles instead.
Toyota has been developing hydrogen internal combustion engines, and Akio Toyoda believes “this new engine will destroy the entire EV market.” He has also expressed worries about the environmental impact of battery production and disposal, the restricted range of electric vehicles, and the absence of infrastructure for charging.
However, it is crucial to understand that Toyota is not dismissing electric vehicles completely. The brand has released many hybrid and plug-in hybrid models and intends to release more.
Toyota’s vision for hydrogen internal combustion engines
Toyota pioneered hybrid electric vehicle technology with the first-generation Prius back in 1997 and later expanded its hybrid lineup to encompass models ranging from compact cars to SUVs. Toyota sold 15 million hybrid electric vehicles globally in 2020.
Toyota’s vision for hydrogen Internal Combustion Engines (ICE) is now part of a campaign to promote hydrogen-powered vehicles as a zero-emission alternative to gasoline and diesel-powered automobiles. According to the CEO, Akio Toyoda, the company is working on a new internal combustion engine that runs on hydrogen that could eliminate the EV industry.
Can Toyota’s hydrogen combustion engine make electric vehicles redundant?
Probably not. But it is too soon to tell. Although all things considered, Toyota’s hydrogen combustion engine is unlikely to render electric vehicles redundant. Toyota’s hydrogen combustion engine is an intriguing advancement in hydrogen fuel technology because it only emits water as a byproduct, but it has some limitations.
Furthermore, because there are currently few hydrogen refueling facilities, hydrogen combustion engines face infrastructure issues. It limits their potential uptake and consumer appeal.
As a result, hydrogen combustion engines may play a niche role in the transportation business, particularly in applications where hydrogen fuel’s long range and faster refueling periods make it a more appealing option than battery-electric vehicles (BEVs).

However, hydrogen combustion engines are unlikely to become the dominant technology in the transportation industry, especially as battery-electric vehicles gain popularity and charging infrastructure continues its onward trajectory.
Many factors will ultimately influence the adoption of sustainable transportation solutions, including technological advancements, infrastructure investments, consumer preferences, and government regulations. While hydrogen combustion engines are an intriguing prospect, they are unlikely to be the main driver of the transportation industry’s future.
Challenges of hydrogen combustion engines and hydrogen-powered vehicles
Hydrogen combustion engines face several challenges that limit their potential as a long-term solution for sustainable transportation:
Infrastructure: The structure of a hydrogen refueling infrastructure is still in its early stages, with only a few hydrogen refueling stations available. It restricts the potential adoption and consumer appeal of hydrogen combustion engines.
Pollutants: Hydrogen contains no carbon, so the exhaust emits no carbon-based pollutants. However, hydrogen combustion happens in an environment that includes nitrogen and oxygen; this can form nitrogen oxides known as NOx.
Fuel Storage: Hydrogen has a low energy content by volume. It makes compactly storing hydrogen difficult since this requires low temperatures, chemical processes, or high pressures.
Cost: Hydrogen contains less energy per unit volume than all other fuels, so shipping, storage, and distribution to the point of use becomes more expensive. Therefore, this reduces the likelihood of broad adoption of hydrogen combustion engines.
Safety: Because hydrogen is a highly combustible gas, there are issues with storing and managing hydrogen in automobiles.
Consumer acceptance: Hydrogen combustion engines are not yet well-known or widely understood. It limits their appeal compared to other sustainable transportation options, such as battery-electric vehicles.
The Bottom Line: The consumer will decide
Based on all the above factors, it is unlikely that hydrogen combustion engine vehicles will bring down the EV industry. The reasoning that it might is far-fetched and too ambiguous to predict since both battery-run EV and hydrogen-powered solutions have unique advantages and limitations.
Hydrogen-powered vehicles have more range and faster refueling times than battery-electric vehicles. They also produce water as a byproduct, making them an appealing option for people concerned about emissions, but again, there is NOx.
Hydrogen can be costly and energy-intensive, and the technology is still in its infancy. Battery-electric vehicles, on the other hand, have the advantage of being more broadly available and accessible, with charging infrastructure expanding rapidly across the world. In the future, they may also get fueled by renewable energy sources to reduce emissions further.
Finally, only the consumer can decide. We know that both hydrogen combustion engine vehicles and battery-electric vehicles have the potential to contribute significantly to a sustainable transportation system. It is doubtful that either technology would replace the other; instead, they will coexist and serve different purposes depending on specific circumstances and preferences of consumers.
