TOKYO (Reuters) – Having invested closely in hydrogen, a expertise derided by Tesla chief Elon Musk as “extremely dumb”, Toyota Motor Corp is making a renewed push for gas cell automobiles to fill a job in a future dominated by electrical battery autos.

Japan’s greatest automaker believes each applied sciences – all-electric battery automobiles just like the Tesla Mannequin X on one hand and Toyota’s hydrogen Mirai on the opposite – will likely be wanted to totally usurp gasoline automobiles. 

“We don’t actually see an adversary ‘zero-sum’ relationship between the EV (electrical automobile) and the hydrogen automobile,” Toyota chairman Takeshi Uchiyamada informed Reuters forward of the Tokyo auto present. “We’re not about to surrender on hydrogen electrical fuel-cell expertise in any respect.”

Toyota started pitching its fuel-cell automobile as a mainstream gasoline automobile various in 2014 when it launched the Mirai with a price ticket of seven.24 million yen – virtually $70,000 on the time.

The automobile has since been launched in the US and different nations world wide. However preliminary pleasure has pale as main markets together with China and Europe have tilted closely towards electrical autos.

Simply four,300 Mirais have been bought, in comparison with round four million models of the Prius, Toyota’s blockbuster hybrid that ushered within the age of the EV.

Uchiyamada, who is called the “father of the Prius”, says Toyota isn’t anti-EV and is investing closely in applied sciences such all solid-state lithium-ion batteries to make them extra fascinating.

But it surely additionally sees some benefits for hydrogen automobiles, that are propelled by electrical energy generated by gas cells.

One main difficulty going through EVs is the size of time they take to cost – as much as 18 hours in some instances – and an issue being amplified as automakers pack in additional batteries to increase vary.

Fast charging expertise helps to resolve this difficulty. However a 30- to 40-minute wait remains to be too lengthy for a lot of atypical drivers with busy lives, says Yoshikazu Tanaka, the chief engineer in command of Toyota’s Mirai.

What’s worse, speedy charging when used too typically compromises battery life considerably, he and different engineers say.

Whereas a hydrogen automobile can refuel in below 5 minutes, the excessive value of the expertise and a scarcity of refuelling stations is an issue, one thing Toyota has been centered on addressing.

The corporate has joined forces in Japan with rivals Nissan Motor Co and Honda Motor Co, and with vitality firms corresponding to JXTG Nippon Oil & Vitality to construct a community of refuelling stations that now totals 91.

Tanaka additionally desires to considerably lengthen the automobile’s driving vary to compensate for the shortage of fuelling stations.

Whereas nonetheless on the idea stage, Tanaka desires to elevate the “sensible driving vary” of the Mirai to about 500 km (310 miles) from the present 350-400 km (190-250 miles). A gas cell automobile’s sensible vary normally dips to 65-70 p.c of its “sticker” vary – 650 km for the Mirai – as a result of drivers typically use air-conditioning and speed up with abandon.

Making the gas cell system extra environment friendly and attempting to realize extra propulsion energy from a given quantity of hydrogen will likely be key, Tanaka stated. He additionally desires to bundle the automobile extra effectively to realize extra space for storing for bigger gas tanks.


Toyota says probably the most promising markets for hydrogen automobiles is China – a key advocate of electrical automobiles however one which is starting to embrace fuel-cell expertise as properly.

Final month, Shanghai introduced plans to promote improvement of fuel-cell autos by including hydrogen refueling stations, subsidizing firms creating fuel-cell applied sciences and organising R&D amenities. Town’s objective is to place 20,000 hydrogen fuel-cell passenger autos and 10,000 industrial autos on the street by 2025.

”Chinese language policymakers go to us and we go to them continuously” to debate Toyota’s hydrogen fuel-cell expertise, says Katsuhiko Hirose, a inexperienced tech engineer at Toyota. 

Toyota was set to check hydrogen fuel-cell automobiles in China this month as a part of an effort to find out the feasibility of promoting the Mirai there.

But it surely’s not all nearly automobiles.

In an effort to encourage different industries to make use of hydrogen, Toyota and Air Liquide S.A. helped arrange the Hydrogen Council, a worldwide foyer launched in January on the sidelines of the World Financial Discussion board in Davos.

With 27 members together with automakers Audi, BMW, Daimler, Honda, Hyundai, and vitality firms corresponding to Shell and Whole, the Hydrogen Council has lobbying policymakers and buyers on hydrogen.

The council’s major argument is that electrical energy provides may be restricted and unstable in excessive demand. That’s as a result of energy grids have small buffers as electrical energy can’t be saved simply and transported. Giant-scale adoption of hydrogen can remedy that difficulty, stated Toyota’s Uchiyamada, who can also be co-chair of the Hydrogen Council. 

Electrical energy generated through the evening, which normally goes to waste when unused, and electrical energy generated by photo voltaic and windmills may be saved and simply transported as liquid hydrogen, very similar to gasoline.

“Elon Musk is true – it’s higher to cost the electrical automobile straight by plugging in,” stated Tanaka. However hydrogen has a spot as a viable various to gasoline, he added.
