Reference Answer
### Technical Viability
Hydrogen (H₂) presents significant technical challenges and opportunities as a marine fuel. Its viability is contingent on overcoming hurdles related to its physical properties, storage, and application in propulsion systems.
* **Combustion & Engine Technology:**
* **Properties:** Hydrogen has a very high auto-ignition temperature (~571°C) and an extremely wide flammability range (4-75% in air). Its high flame speed increases the risk of engine knocking.
