Why don’t we use hydrogen engines?
Lack of refueling infrastructure. High cost of hydrogen production. Limited vehicle market with high costs. Energy efficiency concerns. Saudi Arabia, Australia, China, India and countries in European Union are leading the green hydrogen market with large scale green hydrogen production plants. In 2024 about 1,572 green hydrogen projects were in pipeline of which around 434 projects reached the FID. Final Investment Decision) stage worth USD 75 billion .Costly: Hydrogen is significantly more expensive than using fossil gas for heating and could add on average 70% to heating bills from 2025 for both electricity and fossil fuel-based hydrogen, according to a study by Cornwall Insight.Production of green hydrogen costs between three and four dollars per kg (~Rs 230 and Rs 350 per kg). All major economies, including India, are working towards reducing this to bring it to around one or two dollars a kilogram (~Rs 80 or 150 per kg).Hydrogen is a powerful, transportable energy carrier that can produce electricity, power industry, and enable transportation. Unlike fossil fuels, when hydrogen is burned, it generates only water as a byproduct, meaning no harmful greenhouse gas emissions. For this reason, it is an attractive fuel for the future.
What is the biggest problem with hydrogen cars?
The key problem for hydrogen cars is not the fuel cell but actually getting the clean hydrogen where it is needed. The gas is highly flammable – with all the safety concerns that entails – must be stored under pressure and leaks easily. Tesla CEO Elon Musk called hydrogen “the most dumb thing I could possibly imagine for energy storage.Tesla Unveils Plan For First Hydrogen-Powered Vehicle, Model H By 2026. Elon Musk, known for his bold ideas, has announced Tesla’s shift from electric to hydrogen power, a surprising move given his previous criticism. This decision to be a response to the intense competition from China’s BYD.Musk’s seemingly insatiable appetite for controversy extends to his emphasis on his long-time opposition to hydrogen as an energy source. Earlier this month, he called hydrogen fuel cells “the most dumb thing I could possibly imagine for energy storage.
Will hydrogen engines overtake electric?
You can go cross-eyed if you stare at a crystal ball for too long, but hydrogen cars are less efficient than battery electric ones and the necessary infrastructure just isn’t there. Hydrogen cars may be part of the future, but it’s unlikely hydrogen will be the power source of choice for most car buyers. What is the mileage per kg of hydrogen cars in India? Mileage usually varies because of driving patterns, models, and road conditions. Still, you can expect 250 kms on one kilogram of hydrogen.A fuel cell car can travel about 100 kilometers on one kilogram of hydrogen. This makes the cost per kilometer of a hydrogen car currently about the same as for combustion vehicles.Hydrogen fuel cell cars originate in Japan and South Korea, which still dominate the market for hydrogen vehicles today. China is capturing the advantage of hydrogen to decarbonize buses and trucks with about 85% market share of hydrogen commercial vehicle shipments in 2021.
What is the biggest problem with hydrogen fuel?
Hydrogen is highly flammable, igniting more easily than many other fuels. This presents significant safety challenges, particularly during transportation and storage. Leak detection is especially difficult, as hydrogen is colorless, odorless, and its small molecules can escape through tiny cracks. Specifically, hydrogen has a wide range of flammable concentrations in air and lower ignition energy than gasoline or natural gas, which means it can ignite more easily. Consequently, adequate ventilation and leak detection are important elements in the design of safe hydrogen systems.One major issue is the inefficiency of producing and storing hydrogen fuel. The process of creating hydrogen gas through electrolysis or reforming natural gas requires a significant amount of energy, often derived from non-renewable sources.Lack of refueling infrastructure. High cost of hydrogen production. Limited vehicle market with high costs. Energy efficiency concerns.One of the biggest disadvantages of hydrogen energy is the cost of producing and storing hydrogen. Currently, the process of electrolysis is relatively expensive and energy intensive. Additionally, hydrogen is a gas at room temperature and must be stored in high-pressure or cryogenic tanks.
