Summary of Key Points
Japanese Prime Minister Yoshihide Suga’s visit to India resulted in a cooperation agreement with Narendra Modi to utilize cow dung for producing biogas to power vehicles. Scientifically, using biogas (whose main component is methane, similar to natural gas) as fuel for vehicles is feasible, and such practices have existed in history. Japanese automakers like Suzuki are interested in India’s vast resources of cow dung and its large automobile market, hoping to overtake their competitors in the fields of electric and hydrogen energy. However, the Indian market is currently dominated by motorcycles and three-wheeled vehicles, and the widespread adoption of biogas-powered cars faces numerous challenges related to infrastructure and consumer demand. The risks associated with Japan’s bet on this niche market deserve careful consideration.
1. Biogas-powered cars are not a novelty; they’ve been around for a while!
Many people think using cow dung-derived biogas as fuel is a gimmick, but it is scientifically sound: biogas is produced by the decomposition of organic matter, and its main component, methane, is almost identical to that of natural gas. Therefore, there is no significant difference between using biogas or natural gas for driving.
As early as the 1960s, during a fuel shortage, buses in Shanghai and Jinan began using biogas as fuel; in 2002, Anshan used waste to produce biogas for vehicles and received a $1 million grant from the United Nations. At that time, natural gas-powered cars were considered a new and popular energy source, and many gas stations were built across the country. It was only with the rise of electric vehicles that biogas-powered cars fell out of favor.
2. Why is Japan focusing on Indian cow dung? Fear of losing in the new energy race!
Japan has struggled to make the right moves in the field of new energy: it has fallen behind China and Tesla in the development of electric vehicles, and its investment in hydrogen energy, despite significant efforts and advanced technology, has not been successful. In 2023, China became the world’s largest market for hydrogen-powered cars, leaving Japan far behind.
In this context, Indian cow dung has become a potential solution: with 300 million cows in India, the waste could be used to produce biogas on a large scale. Suzuki experts have calculated that the manure from just 10 cows is enough to power a car for a day, and the cost of collecting it (7 cents per kilogram) is very low. Japan hopes to leverage this advantage in the Indian market, which has a relatively low car ownership rate (34 cars per thousand people).
3. Is the Indian automobile market an untapped opportunity? Already dominated by motorcycles!
Although the Indian automobile market seems promising, it is actually dominated by two-wheeled vehicles: there are 220 million motorcycles in India, with sales exceeding those of cars last year. The reasons for this include:
- Low cost: The most popular motorcycles cost around 4,100 yuan, which is affordable for many;
- Practicality: Poor road conditions and chaotic traffic make motorcycles more convenient and flexible;
- Strong competition: Indian motorcycle manufacturers account for half of the world’s top ten, with Honda using India as a major production base and even exporting to Africa.
Additionally, India is the largest market for electric three-wheeled vehicles, with annual sales exceeding 1 million units. There are not enough people willing to buy cars, so biogas-powered cars may have limited appeal.
4. Overcoming barriers to the widespread adoption of biogas-powered cars!
Even if the technology and resources are available, there are many challenges to overcome before biogas-powered cars can become popular in India:
- Infrastructure: A large number of biogas production plants and gas stations need to be built, but India has not yet addressed basic sanitation issues, making this difficult;
- Consumer demand: Few people are willing to switch to biogas-powered cars just for the lower cost;
- Japan’s history of betting on niche markets: Japan has a history of investing in unproven technologies with little success.
5. Many “novel” fuels have been tried globally, but only Brazil’s biofuel succeeded!
Humans have experimented with using coffee waste, seaweed, and even nuclear reactors for fuel, but only Brazil’s biofuel program has become a successful industry. The reason is:
- Abundant resources: Brazil has abundant sugarcane;
- Strong government support: The government mandated the blending of ethanol with gasoline and provided subsidies;
- High demand: To reduce dependence on imported oil and ensure energy security.
With India’s limited policy support for biogas, it is uncertain whether a viable biofuel industry can be established. Whether biogas-powered cars will succeed depends on whether India and Japan can solve these practical problems.
In summary, the idea of using cow dung to produce biogas for vehicles is innovative, but its implementation faces significant challenges. For Japan to succeed, it must first overcome the dominance of motorcycles in the Indian market and address the infrastructure gaps.
