Could charcoal power a steam-assisted ironclad?

Charcoal could provide limited steam assistance, but uncertainty over its energy density makes long ocean voyages a different problem.

Question

Could charcoal be used to power ships?

Short answer

Yes, for limited steam assistance. Its suitability for long voyages is doubtful, making a ship resembling HMS Warrior a more plausible endpoint.

Notes

Charcoal could power a steam-assisted warship and let it move against the wind. The uncertainty concerns whether the fuel carries enough energy for a long voyage. An Atlantic crossing under steam is therefore treated much more cautiously than occasional engine use. HMS Warrior provides the comparison for a vessel that combines this limited steam capability with sail.
