Researchers from the Indian Institute of Technology, Delhi have come up with a way to generate clean fuel hydrogen from water at a low-cost, which is a significant step towards efforts across the globe that are being made to look for cleaner and greener energy sources.
A fuel cell works much like an electric battery, converting chemical energy into electrical energy.
What is hydrogen?
Key-highlights of the research
Sulphur-Iodine (SI) thermochemical hydrogen cycle
I2 + SO2 + 2 H2O heat→ 2 HI + H2SO4 (120 °C)
The HI is then separated by distillation or liquid/liquid gravitic separation.
2H2SO4 heat→ 2 SO2 + 2 H2O + O2 (830 °C (1,530 °F))
The water, SO2 and residual H2SO4 must be separated from the oxygen byproduct by condensation.
2HI → I2 + H2 (450 °C)
Iodine and any accompanying water or SO2 are separated by condensation, and the hydrogen product remains as a gas.
Net reaction: 2 H2O → 2 H2 + O2
Verifying, please be patient.
