Thread: Full list of hydrogen concept cars


  1. Default

    What makes a hydrogen car possible is a device called a fuel cell, which converts hydrogen to electricity, giving off only heat and water as byproducts. Because it's non-polluting, hydrogen seems like the ideal fuel for the 21st century. A lot of people in the government and the auto industry are excited about its potential. Hydrogen cars have the potential to be fuel-efficient and offer the hope of eco-friendly, green driving. But there are still a lot of problems that need to be overcome and questions that need to be answered before hydrogen becomes the fuel of choice for enough people to make much difference in our current use of fossil fuels. For instance, where will we get the hydrogen? How expensive will these fuel-efficient cars be to purchase? Will you be able to find a hydrogen fuelling station to refill your tank? And, perhaps most importantly, as a fuel, is hydrogen really as non-polluting as it seems?

    These are good questions that many people are trying to answer.

    I think the first concept we must define, is the place of hydrogen in an energy stream. Hydrogen is an energy carrier. Except for thermo-nuclear reactions, that is all it can be. It is not a fuel.

    We must use some form of energy to produce the hydrogen which stores and carries the energy to be used in producing work of some sort. That initial form of energy is really the first step. As solar energy becomes more prevalent and excess energy is available, simple electrolysers can be used to store the excesses in the form of hydrogen to be used later or elsewhere.

    Nuclear energy is an obvious primary energy source and hydrogen can be used to store and carry that energy.

    Fossil fuel energy sources are best used directly to minimize use until we can eliminate them all together as an energy source. However, hydrogen via small additions to combustion can help clean up and extend these fossil energy sources.

    This is a huge topic that will see an answer over our lifetimes.
