What is the disadvantage of hydrogen?
Disadvantage: Hydrogen Storage and Transportation Compressing the hydrogen requires about 13% of the total energy content of the hydrogen itself, and if it is liquefied it loses about 40%. Hydrogen gas is highly flammable and can easily escape containment. If hydrogen gas escapes containment, it can corrode metals.
Why don’t we use fuel cells?
Hydrogen is only as clean as the energy used to produce it. Current hydrogen vehicles use fuel cells to convert the chemical energy to power. Fuel cells are very costly because they are complex and require expensive materials such as platinum.
How much does it cost to fill up a Toyota Mirai?
From three-quarters of a tank, we paid nearly $75 to fill up. This won’t be an issue right away, as the Mirai comes with $15,000 or 3 years’ worth of free hydrogen. That’s enough for 160 complete fills, and even if the Mirai were to only manage 250 miles per tank, would take you to around 37,500 miles.
Why is ethanol in fuel not a better alternative to hydrogen?
Ethanol Fuel is a Source of Hydrogen One disadvantage of ethanol fuel is that it has been reported to cause engine burns and corrosion. To be able to utilize it in a more productive way, researchers are looking to convert it into hydrogen form, which should uplift it as a formidable alternative source of fuel.
How reliable are fuel cells?
Hydrogen fuel cells are a clean, reliable, quiet, and efficient source of high-quality electric power. They use hydrogen as a fuel to drive an electrochemical process that produces electricity, with water and heat as the only by-products.
What are the downsides of green hydrogen?
Cons
- High cost due to expensive raw materials like platinum.
- Reliability, durability and robustness are still under research.
- Growing infrastructure for hydrogen delivery.
- Safety concerns with hydrogen.
- Low density of fuel, compared to gasoline.
Why is green hydrogen expensive?
Because it does not use electrolysis and renewable energy, its hydrogen will be cost-competitive with gray hydrogen.
