David Wooley and Ed Carr, lead authors in the shipping industry, discuss future ship fuels, policies, and California's role in decarbonization. Topics include alternative fuels like ammonia and methanol, wind tech, slow steaming, clean electricity, enforcement mechanisms, costly technology investments, global efforts, and policy recommendations for the US and California to drive industry change.

Episode notes
Shipping's Significant Emissions
- Shipping emissions equal Brazil's total emissions and nearly match aviation's global emissions.
- This presents a major climate and health concern, especially for port communities.
Uncertainty in Shipping Decarbonization
- There's no consensus on decarbonizing shipping, unlike other sectors like cars or heating/cooling.
- Shippers face a complex choice between potentially stranded asset fuels and the high cost of new technologies.
Hydrogen vs. Methanol/Ammonia
- Cryogenic hydrogen is impractical for ships due to the equipment needed to maintain low temperatures and pressure.
- Methanol and ammonia, derived from hydrogen, are more stable fuel options.
