According to foreign media reports, hydrogen fuel cells may become an important part of future sustainable energy. Fuel cells are more like internal combustion engines in that highly efficient hydrogen fuel cells use a reversible electrolytic chemical reaction to generate electricity. The fuel is more environmentally friendly, and its only products are electricity, water and heat.
Challenge 1: Fuel cells and hydrogen are too expensive
The cost of hydrogen energy has always been high, but the surge in natural gas production in the United States has made hydrogen much cheaper than before. In addition, electrolysis can be used to split hydrogen into water. What's more, hydrogen costs less than gasoline today. The researchers also discovered ways to use relatively inexpensive materials in making fuel cells. At least for now, when talking about cost, hydrogen energy batteries also have a certain degree of competitiveness.Also read:https://www.aimeno.com/lithium-battery-pack/190.html
Challenge 2: Storage of hydrogen is difficult
The storage of hydrogen is challenging because hydrogen is a gas, which will inevitably lead to hydrogen storage taking up a lot of space and requiring large storage tanks with thick walls, which is a headache for hydrogen energy vehicles. Fortunately, a number of companies have successfully developed a system that can be used by commercial vehicles to transport hydrogen in the same way as ammonia.
Challenge 3: At present, the world is still focusing on the weak infrastructure of petroleum fuel hydrogen
In fact, the current hydrogen infrastructure is not strong, but in many developed countries, natural gas and water infrastructure can still be seen. Both types of substances can be used to synthesize hydrogen at a cost comparable to or slightly lower than that of gasoline. This eliminates the need for a trailer for hydrogen consignment, or enables direct generation of hydrogen on site.
The promotion of fuel cells has not been more feasible earlier. Not only that, many places have begun to implement it. Toyota has successfully cooperated with Mirai, while Honda and Hyundai are also positioning hydrogen fuel vehicles and plan to compete with their competitors in the industry.
Therefore, in order to reduce the use of petroleum fuels as much as possible, the application of fuel cell technology still has a long way to go, but its aim is to reduce emissions and solve the problem of energy depletion. The future of fuel cells looks bright.
