INDUSTRIAL GAS companies are making progress in developing hydrogen as a large-scale fuel for vehicles,but they caution that many hurdles still need to be overcome before a true hydrogen economy can emerge.Rich Deal,vice president of hydrogen,syngas and on-sites for Air Liquide in the US,says...
Hydrogen is also used as a propellant is NASA rockets and hydrogen peroxide is used as fuel in some jetpacks and racecars. Many who argue that hydrogen fuel is really an energy carrier are battery electric car enthusiasts. What they fail to mention is that electrical batteries and capacitors,...
are not a reason to “just give up" on hydrogen fuel-cell tech. “We may need it for many other reasons in the future,"cautioned Paltsev, citing geopolitical issues as a factor that could disrupt (中断) access to raw materials for batteries, thus making hydrogen cars suddenly more ...
What is the biggest challenge for the hydrogen fuel cars?A. They cost more than we expected.B. There isn’t enough fuel for them.C. There is lack of refueling stations.D. They are difficult to control on the road.答案：C 分析：解析:细节理解题。从第二段第二句可知,对于氢气汽车来讲,最...
This may not be a word-for-word transcript. Narrator: Hydrogen has been hailed as a fuel of the future that could help end the world’s dependence on fossil fuels and aid the transition to net-zero …
are not a reason to "just give up" on hydrogen fuel-cell technology. "We may need it in many open ruses in the future," said Palaeve, crime political issues as a factor that could disrupt(中断) access to raw materials for batteries, thus making hydrogen cars suddenly more economically ...
The use of hydrogen fuel cells for cars is strongly promoted by the governments of many countries and by international organizations like the European Community. The electrochemical behaviour of the most promising fuel cell (polymer electrolyte membrane fuel cell, PEMFC) is critically discussed, based...
hydrogen cars back is the lack of adequate refueling stations.At this point in time, it looks as if Germany and Japan will be leading the charge in building this hydrogen refueling station within their countries.The electric car is also a vehicle that is here now and has been for a while...
We look at the chemistry of water-emitting fuel-cell electric cars (FCEVs) and how the tech might save motoring as we know it
The most recent use of hydrogen fuel as an alternative to fossil fuel (gasoline) is in automobiles. The hybrid cars—partly fueled by hydrogen— have been quite successful. Automobiles completely powered by hydrogen are also forecasted for the near future—within the next few years. One maker ...
