Fuel cellsHydrogen fuelA new technological concept of electric energy generation appeared in the last years. The concept of energy generation via "fuel cell" is becoming more and more important for energetic planning, due to its sole characteristics. This paper aims to relate and discuss the ...
“They understand from a cost point of view — and steel is all about cost — they understand that they will not be cost competitive if they try to produce ammonia in one country, crack it back to hydrogen and put it into DRI,” she said. “You will be out of cost. So they want ...
Biofuels, while not quite "zero emission" from the exhaust pipe (though a lot cleaner than petrol and diesel), would be cleaner overall even than the fuel-cell technology now being touted as an alternative to the internal-combustion engine. That is because the hydrogen that fuel cells use ...
Uber customers in Berlin will soon be able to hail “up to 200” Toyota Mirai hydrogen cars from their smartphones as part of an ongoing two-year pilot project called H2 Moves Berlin. “Hydrogen vehicles have a special advantage when it comes to passenger transport,” says the project — a...

It would then remove the problem of the cost of storage, transportation and reconversion to electricity which hangs on to the use of hydrogen itself. On the other hand its use would provide, in practice, a "liquid form" of hydrogen. 展开 ...

In order to realize combined advantage of hydrogen and renewable energy systems, two new cogeneration of hydrogen and electricity frameworks are ...
Describe five advantages and five disadvantages of a hydrogen economy. What are the three different standardization methods? Give an advantage of What is the disadvantage of NH_4OH? What are the key advantages, limitations, and sources of error of the titrimetric m...
Graphene constructed carbon paste electrodes, surface film modified electrodes, and micro/nanoelectrodes have been developed to determine various species, such as glucose, DA, AA, nicotinamide adenine dinucleotide, hydrogen peroxide, and DNA [74]. These graphene-based electrodes are promising for ...
虽然电动汽车是新能源汽车的主流,但是氢能汽车也是很多企业的重点发展方向之一。并且,和电动汽车相比,氢能汽车也有一些自己独有的优点。而近日,智车派注意到,大众汽车的一项氢燃料电池专利被海外媒体曝光了。 根据海外媒体报道的信息,大众汽车和德国公司Kraftwerk Tubes...
