Have look at the page on efficiency for more information. It is this energy source that is one of the major problems with hydrogen the hydrogenpowered fuel cell in your car might appear to produce no pollutants but did the original energy needed to fill the cell? Hydrogen is the hardest gas to compress and the efficiency is about 40 at best.
By then, suspect, personal public transport, if it exists will have two wheels or four legs. Although hydrogen is the commonest substance in the Universe, it does not exist as free gas or liquid on Earth so it has to be produced. Unfortunately, because something is lost whenever one form of energy is converted to another, the hydrogen produced has only 50 of the energy value of the original gas. What is the truth about this marvellous new fuel?
If you are generating electricity, it is better to use it directly
For distribution, electricity has one of the major problems with hydrogen the hydrogenpowered fuel cell in your car might appear to produce no pollutants but did the original energy needed to fill the cell? Production As mentioned, hydrogen creation needs hydrogen source and an energy source. Although hydrogen is the commonest substance in the Universe, it does not exist as free gas or liquid on Earth so it has to be produced. The systems for creation, storage, transfer and supply to users would have to be built virtually from scratch over the next couple of decades, enough to cover whole countries.
The infrastructure for electricity transfer already exists while that for hydrogen is, at the moment, almost nonexistent.
By then, suspect, personal public transport, if it exists will have two wheels or four legs. If by road, it would require 13 more tankers so about in lorry accidents would,on average, involve tanker. The infrastructure for electricity transfer already exists while that for hydrogen is, at the moment, almost nonexistent. Although hydrogen is the commonest substance in the Universe, it does not exist as free gas or liquid on Earth so it has to be produced.
