Hydrogen fuel cells
Pros: No vehicle emissions other than water vapor. Fuel economy equivalent to about twice that of gasoline vehicles. Hydrogen is abundant, and can be made from renewable energy. Cons: This space-age technology is expensive.Fuel Cell Benefits: 5 Facts You Should Know
- Zero-Emission Power. Hydrogen fuel cells (HFCs) produce no harmful emissions, eliminating the costs associated with handling and storing toxic materials like battery acid or diesel fuel.
- Robust Reliability.
- Improved Efficiency.
- Scalable.
- Lower Operational Costs.
If it is not produced using renewable sources, hydrogen pollutes. To date, more than 96% of the hydrogen used is grey. It costs less, but its impact on the environment is so great that 10 kilos of carbon dioxide are produced for every kilo of hydrogen obtained.
What are the advantages and disadvantages of fuel cells : Fuel cell advantages and disadvantages
As energy converters, fuel cells are efficient and environmentally friendly. Compared to combustion engines, however, they are – as of today – also significantly more expensive. In combination with batteries, high power and high energy density can be optimally combined.
What are the 3 cons of hydrogen
Hydrogen is a highly inflammable substance and explosive in nature; it cannot be easily transported from one place to another and it can be generated by the hydrolysis of water but it is a very expensive process.
What are disadvantages of hydrogen fuel cells : Disadvantages:
- Expensive to manufacture due the high cost of catalysts (platinum)
- Lack of infrastructure to support the distribution of hydrogen.
- A lot of the currently available fuel cell technology is in the prototype stage and not yet validated.
- Hydrogen is expensive to produce and not widely available. Privacy.

Why hydrogen fuel cells are bad
Hydrogen used in fuel cells does not result in carbon emissions, only electricity, water, and heat. The production of hydrogen through steam methane reforming (SMR) produces emissions that are known to be harmful, including NOx, particulate matter, carbon monoxide, and volatile organic compounds (VOCs).Hydrogen is a highly inflammable substance and explosive in nature; it cannot be easily transported from one place to another and it can be generated by the hydrolysis of water but it is a very expensive process.What are the Disadvantages of Hydrogen Fuel Cells

There's virtually no pure hydrogen on Earth because it's so reactive. Most hydrogen is made from methane [natural gas] in a process that produces carbon dioxide and other greenhouse gases. Hydrogen can also be made from water using electrolysis, but that requires electrical energy.
Why are hydrogen fuel cells not efficient : “Fuel cells have more heat generation, so they run hotter,” he explains. “You have to put more energy towards the cooling fans and they degrade over time. An engine doesn't really age in efficiency, but a fuel cell will age and it won't be as efficient [at the end of its life compared to its beginning].”
Is hydrogen fuel cell the future : Hydrogen is an energy carrier with qualities that can help reduce the net sum of greenhouse gas emissions. However, while battery-electric vehicles and machines and biofuels can decarbonize transport already today, large scale hydrogen powered transports and infrastructure still belong to the future.
How long will a hydrogen fuel cell last
about 150,000–200,000 miles
The fuel cell stacks are designed to last the lifetime of the vehicle, about 150,000–200,000 miles. At the end of its lifespan, the fuel cell will be disassembled and the materials recycled, similar to what happens with vehicle components today. A fuel cell stack is about the size of a roll-aboard suitcase.
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.Storage and transportation: Hydrogen is bulky and requires special storage and transportation infrastructure, making it expensive and complex. Infrastructure: There's a limited number of hydrogen fueling stations, making it inconvenient for widespread use compared to the.
Why hydrogen fuel is not the future : The Problem
While hydrogen itself is a clean fuel, the process of extracting it is, at present, not climate-friendly and very energy-intensive. Depending on the method and technology used, extracting it may use more energy than it provides as a fuel. Production of hydrogen from coal and natural gas also releases CO2.
