Anthracite coal is up to 85.7% carbon by weight the rest is not pure hydrogen but a mix of sulfur, oxygen, nitrogen, and hydrogen. (And yes, that Oxygen lowers the energy density while increasing CO2 release.) Natural gas is 25% hydrogen 75% carbon. Burning hydrogen produces water not CO2. So, while the specific bonds play a role the actual carbon vs. hydrogen content is a major issue. |
