China is betting big on another gas engine alternative: methanol cars

As the Chinese authorities works to scope ambitious c goals—an emissions highest by 2030 and neutrality by 2060—the state has go a planetary person successful the adoption of electrical vehicles. But that’s not the lone greener car alternate it’s pursuing. 

Earlier this month, connected September 16, China’s Ministry of Industry and Information Technology said it would “accelerate the popularization of methanol cars” and “explore the ‘green methanol + methanol cars’ model.” The adjacent day, the manager of China’s National Energy Administration, Zhang Jianhua, said that the state is “actively exploring caller ways to regenerate fossil fuels, similar greenish hydrogen, methanol, and ammonia.” 

Commonly called “wood alcohol,” methanol is simply a elemental integrated chemic that tin beryllium produced from a assortment of sources, including coal, earthy gas, biomass, and captured c dioxide. As a fuel, its advantages are clear: methanol is arsenic almighty arsenic accepted fuel, but greener. It has already been wide utilized successful racecars, for instance, due to the fact that it gives the motor much horsepower portion keeping it cooler. In immoderate scenarios similar long-haul transportation, methanol-powered vehicles tin beryllium much affordable and dependable than EVs. 

According to Leslie Bromberg, main probe technologist astatine the Massachusetts Institute of Technology’s Plasma Science and Fusion Center, who has studied the imaginable of utilizing methanol successful proscription successful the US, methanol engines tin beryllium comparable successful ratio to diesel engines “without the occupation of diesel emissions.” 

For a decade, methanol substance has been discussed and piloted successful China arsenic a mode to modulation the automotive manufacture into a aboriginal with little contamination and little dependence connected fossil fuels. But its adoption has agelong lagged. 

Now the government’s caller moves, on with different authorities efforts successful the past twelvemonth to draught standards for methanol cars and enactment applicable industries, reaffirm that China is getting much superior astir the alternate fuel. And methanol is yet capturing nationalist attraction arsenic Chinese automakers look for the adjacent industry-changing innovation—which, conscionable similar EVs, could go some a commercialized occurrence and a governmental boost to China’s climate-tech ambitions.

China’s experimentation with methanol

Today, astir 60% of the world’s methanol is manufactured and utilized wrong China—making the state the planetary leader. It’s presently utilized mostly successful plastics manufacturing.

The state started a methanol-car experimentation successful 2012, encouraging automakers to make models to tally successful a fewer cities portion collecting information connected their economical and biology impacts implicit the adjacent six years. The decision was that methanol cars tin beryllium 21% much vigor businesslike than state cars, portion emitting 26% little c dioxide.

After that aviator phase, the Chinese nationalist authorities released a policy successful 2019 that affirmed its enactment for methanol fuel, peculiarly successful nationalist transport, taxis, and authorities vehicles. 

Methanol is besides an charismatic enactment to powerfulness long-haul dense vehicles similar trucks, says Zhao Kai, the main China typical of the Methanol Institute, a planetary commercialized association. Today’s electric trucks request ample batteries that marque them overmuch little affordable than accepted trucks. But methanol trucks tin outgo astir the aforesaid magnitude arsenic accepted trucks since the engines are similar. 

“The bulk of trucks that are moving connected the roads and delivering parcels successful China are owned by idiosyncratic motortruck drivers,” Zhao says. “They whitethorn not beryllium capable to spend it if the motortruck gets excessively expensive. If they can’t adjacent marque a living, however could they beryllium reasoning astir achieving c neutrality? That’s not thing connected their mind.” 

Nevertheless, the improvement of methanol rider cars successful China remains dilatory compared with different greenish options, similar EVs. In 10 years’ time, the fig of EVs successful China grew from 20,000 to implicit 10 million, portion the fig of methanol cars grew from zero to lone 30,000. 

There are besides less than 200 methanol refueling stations successful China, and they are each located successful the provinces wherever the aviator programs were conducted. That means it’s fundamentally intolerable for methanol cars to question extracurricular the province, oregon adjacent the city, they are in. Future operation of methanol stations volition astir apt trust connected enactment from China’s 2 biggest operators of state stations, Sinopec and CNPC, which collectively run implicit fractional the stations successful China. They person yet to amusement overmuch involvement successful offering methanol services.

A large crushed for the dilatory improvement is that methanol cars person not been included successful the “new vigor vehicles” class that China heavy subsidizes and encourages. When China was drafting rules successful the aboriginal 2000s connected what constitutes a caller vigor vehicle, it lone included cars powered by electricity—pure EVs, plug-in hybrids, and fuel-cell vehicles, says Zhao. Methanol cars, being person to accepted gas-powered cars, were not included and subsequently missed retired connected 2 decades of high-speed growth. 

This means the methanol cars of contiguous stay a section experimentation alternatively than a applicable user option. But much section officials are now giving retired astir $700 successful subsidies to methanol-car buyers and $3,000 toward renovations that let state stations to connection methanol fuel. And Geely, a large home Chinese automaker that besides owns Volvo Cars, has been processing methanol cars since 2005 and debuted respective caller models this year. 

“The exertion and popularization of methanol cars is the astir realistic and effectual way toward steadfast and sustainable improvement successful transportation,” says a spokesperson for Geely, which claims to person produced implicit 90% of the existing methanol cars successful China. Its methanol rider cars person tally a combined 10 cardinal kilometers (6.2 cardinal miles), eliminating 19,400 tons of c emissions that gas-powered cars would person produced. 

What this means for China’s carbon-neutrality targets

A displacement successful reasoning connected methanol happened astir 2020, erstwhile President Xi Jinping announced the carbon-neutrality pledge astatine the United Nations General Assembly meeting. “[China’s] wide improvement extremity of c neutrality has brought astir a large accidental since [then]: radical abruptly realized that methanol is really a carbon-neutral fuel,” Zhao says.

Traditionally, methanol is produced from fossil fuels similar ember and earthy gas, but it tin besides beryllium made from renewable resources similar cultivation waste. A University of Southern California team has adjacent managed to nutrient methanol efficiently from CO₂ captured from the atmosphere. This means that car fuels—as good arsenic different chemic products derived from methanol—can beryllium produced successful a carbon-negative way, astatine slightest theoretically.

Today, the starring institution making methanol from c dioxide is Carbon Recycling International, an Icelandic company. Geely invested successful CRI successful 2015, and they person partnered to physique the world’s largest CO₂-to-fuel mill successful China. When it’s running, it could recycle 160,000 tons of CO₂ emissions from alloy plants each year. 

The imaginable for cleanable accumulation is what makes methanol desirable arsenic a fuel. It’s not conscionable a much businesslike mode to usage energy, but besides a mode to region existing CO₂ from the air. To scope c neutrality by 2060, arsenic China has promised, the state can’t enactment each its eggs successful 1 basket, similar EVs. Popularizing the usage of methanol substance and the cleanable accumulation of methanol whitethorn alteration China to deed its people sooner.

Can methanol determination beyond its soiled roots?

But the aboriginal is not each agleam and green. Currently, the bulk of methanol successful China is inactive made by burning coal. In fact, the quality to powerfulness cars with ember alternatively of oil, which China doesn’t person overmuch of, was a large crushed the state pursued methanol successful the archetypal place. Today, the Chinese provinces that pb successful methanol-car experiments are besides the ones that person abundant ember resources.  

But arsenic Bromberg says, dissimilar state and diesel, astatine slightest methanol has the potential to beryllium green. The accumulation of methanol whitethorn inactive person a precocious c footprint today, conscionable arsenic astir EVs successful China are inactive powered by energy generated from coal. But determination is simply a way to modulation from coal-produced methanol to renewables-produced methanol. 

“If that is not an intention—if radical are not going to prosecute low-carbon methanol—you truly don’t privation to instrumentality methanol astatine all,” Bromberg says.

Methanol substance besides has different imaginable drawbacks. It has a little vigor density than gasoline oregon diesel, requiring bigger, heavier substance tanks—or drivers whitethorn request to refuel much often. This besides efficaciously prevents methanol from being utilized arsenic an airplane fuel.

What’s more, methanol is severely toxic erstwhile ingested and moderately truthful erstwhile inhaled oregon erstwhile radical are exposed to it successful ample amounts. The imaginable harm was a large interest during the aviator program, though the researchers concluded that methanol proved nary much toxic to participants than gas. 

Beyond China, immoderate different countries, similar Germany and Denmark, are besides exploring the imaginable of methanol fuels. China, though, is astatine slightest 1 measurement up of the rest—even if it remains a large question whether it volition replicate its occurrence successful processing EVs oregon travel the way of different state with a large car industry. 

In 1982, California offered subsidies for car manufacturers to marque implicit 900 methanol cars successful a aviator program. The Reagan medication adjacent pushed for the Alternative Motor Fuels Act to beforehand the usage of methanol. But a deficiency of advocacy and the falling terms of gasoline prevented further probe of methanol fuel, and aviator drivers, portion mostly satisfied with their cars’ performance, complained astir the availability of methanol substance and the smaller scope compared with state cars. California officially ended the usage of methanol cars successful 2005, and there’s been nary specified experimentation successful the US since.
