Question

If hydrogen is used as a fuel in rockets why cant it be used in our cars???

Answer 1

Answer:

The sole reason some rockets use liquid hydrogen is because hydrogen is light and rockets tend to be at least 90% fuel, so liquid H2 provide a massive advantage compared to its cost. ... Actually there are internal combustion engines that can burn hydrogen today. They can burn either hydrogen or gasoline

❤Hydrogen is actually used for combustion in rockets and space shuttles were it is stored cryogenically. Even with so much difficulties, hydrogen is preferred because of it's very high energy density and tendency to produce less emissions.❤
