India develops integrated hydrogen storage technology for fuel cell vehicles to promote the realization of zero hydrocarbon economy in the future. It is of great significance to integrate hydrogen storage technology into vehicle fuel cells

in the field of power generation and transportation, people are promoting the replacement of fossil fuels with sustainable alternative energy. In the past decades, people have been discussing the use of renewable energy to produce hydrogen and to provide fuel for automotive fuel cells, so as to achieve a zero hydrocarbon economy in the future. Fuel cell is essentially a battery that can continuously supply chemical energy to generate electricity. Unfortunately, hydrogen is a dangerous substance, so how to safely store hydrogen in vehicle fuel tank has always been the bottleneck of development in this field

according to foreign media reports, researchers from the Vellore Institute of technology in India discussed how to integrate hydrogen storage technology into vehicle fuel cells. The research team said that considering carbon emissions and their impact on the climate, as well as the fact that fossil fuels may become increasingly scarce or even inaccessible due to various geological and political reasons, it is of great significance to turn to renewable energy

the focus of the team is to use carbon nanotubes to store hydrogen, rather than simply pressurize the gas, because the latter has the risk of explosion. Carbon nanotubes can provide a huge surface area in a small volume, thus adsorbing hydrogen molecules to form a more stable form than pressurized gas. According to reports, at a relatively mild 283 degrees Kelvin (about 10 degrees above room temperature) and a pressure of 50 MPa, its intake weight is only slightly higher than 1.14% of its weight. The research team used germanium doped carbon nanotubes to achieve this goal

then, they connected the storage system to the fuel cell and proved that hydrogen entered the fuel cell at a constant rate. The battery can consume this chemical energy and stably generate more than 10000 watts of electricity with such characteristics

the research team said that among working vehicles, thermal conductive plastics are currently the most widely used in the LED field. Lightweight composites can be used to contain doped carbon nanotube powder and ensure that the pressure is maintained for storage. In order to maintain 283 of the contents of the integrated fuel tank, which can solve this problem, the necessary storage temperature of Kelvin degree needs to consume part of the generated power. Obviously, the proportion of fuel cell output in hot climate is much smaller than that in cold environment. Optimizing the synthesis and manufacturing process of this storage method will make it more economically feasible
