Scientists have been trying to figure out how to power cars using hydrogen for years, and have been struggling. This is because it has to be kept at extremely cool temperatures, as hydrogen has a boiling point of -252.8°C in its liquid state which is quite difficult to achieve in a vehicle without large pressurised tanks.
However, there may be a new solution. Scientists from Benaras Hindu University in India have come up with an idea – coconuts.
What makes coconuts a good option for hydrogen-powered cars?
- They are cheap
- They are easily available
- They have good absorption qualities
- Hydrogen can be stored in the carbon particles
- The production of carbon from coconuts is not time-consuming
What are the potential drawbacks of using coconuts for hydrogen storage?
- Coconut composition depends on where it grows– results will be variable
- The amount of hydrogen that can be stored in the carbon from coconuts depends on the temperature (less can be stored at room temperature)
Undoubtedly, more research needs to be done into the practicalities of using coconuts as hydrogen storage for hydrogen-powered cars, but these developments are interesting none-the-less!
Could this be the next step towards the future of driving greener?
