Are hydrogen cars bad for the environment? In fact, it's essentially pollution-free. A hydrogen fuel cell in a car produces zero emissions; the only substances released through its tailpipe are water vapor and heat. Ironically, the carbon dioxide released in the process of producing hydrogen from fossil fuels cancels out any benefits to the environment.
Are hydrogen cars greener than electric cars?
Hydrogen isn't totally green, though – it's clean when used in your hydrogen car but to get the (liquid) hydrogen into the fuel pumps, it requires a lot of energy and a lot of the current production is done using fossil fuels, so it contributes to global warming more than, say, an electric car charged using power from
Are hydrogen engines efficient?
Hydrogen is considered an alternative fuel under the Energy Policy Act of 1992. In fact, a fuel cell coupled with an electric motor is two to three times more efficient than an internal combustion engine running on gasoline. Hydrogen can also serve as fuel for internal combustion engines.
What does Elon Musk say about hydrogen fuel cells?
The materials that go into battery manufacturing are finite, he added, while hydrogen is “by far the most common element of the universe." Musk, in turn, has spent years mocking the idea of using hydrogen fuel cells rather than electric batteries to power next-generation green vehicles.
Does hydrogen leak out of tanks?
The leakage of hydrogen from high-pressure (5000–10,000 psi) tanks to the atmosphere can be essentially treated as an unrestrained, free expansion (called the Joule–Thompson expansion. The immediate consequence of a gas leak is then an overall increase in the ambient temperature.
