Hydrogen filling into the storage tank had been a challenge due to characteristics of hydrogen in its natural state. Hydrogen is dense by weight but not by volume. Hence, hydrogen demands vast storage space.
Numerous ground-breaking technologies have evolved to face this problem and made hydrogen storage commercially viable.
Here are 5 reasons why hydrogen filling technology is ready to achieve hydrogen economy
- Achieving desired pressure is no more a problem
Electrolysis by hydrogen electrolysers is followed by the hydrogen compression using hydrogen compressors. The next stage is to pump the gas to storage vessels for delivery to the fuel pump. Hydrogen compressors are designed to achieve desired pressure from 350 or 700 bar with the higher pressure giving greater range. The hydrogen filling station uses a booster pump to make 700 bars.
2.Hydrogen-filled in high pressure with safety equipment
Safety devices are installed to detect any leakage in the storage tank or during refuelling process. Hydrogen is safer than other highly inflammable fuels such as diesels and gasolines.
3.Cycle rate and efficiency
A hydrogen fuel cell is more energy efficient than convenient combustion engine which uses gas or diesel. It consumes more than 55 percent of fuel energy which makes it more economically feasible than conventional fuel source for vehicles.
- Hydrogen production
Hydrogen production by water electrolysis (hydrogen electrolysers) is evidently cheaper than other non-renewable source of energy. Hydrogen filling uses Hydrogen electrolysis which produces only NOx nitrogen oxides (It can be reduced using special techniques)
- Hydrogen economy is finally a reality
Hydrogen filling is economically feasible, efficient and safer which makes it an attractive option for customers. Hydrogen economy also resolves the unequivocal problems posed by the harmful effects of conventional fossil fuels.
