Comparing the Internal Energy of Gasoline and Hydrogen

Click For Summary
SUMMARY

The internal energy of gasoline is relatively stable across temperature and pressure variations, making calculations straightforward. In contrast, hydrogen exhibits significant fluctuations in internal energy based on these factors. The discussion raises the question of whether hydrogen can provide an equivalent energy output to gasoline when measured by equal volume. For detailed energy density comparisons, refer to the provided Wikipedia article.

Calculating the internal energy of gasoline is fairly simple, because it wouldn't vary much with temperature or pressure.

For hydrogen, though, it would vary significantly with each. What sort of ranges would we be looking at?

I'm curious if it would be possible to get the same amount of energy from hydrogen as it would be from an equal volume of gasoline.
