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.
Ammonia and methanol fuels are emerging as alternatives for future ships to decarbonize the shipping industry.
Transitioning to new fuels faces uncertainty due to high costs, risks of stranded assets, and operational complexities on vessels.
Biofuels, like renewable diesel and biodiesel, offer initial emission reductions but are not the sole pathway for complete decarbonization in shipping.

The Urgency of Decarbonizing Shipping to Address Climate Change and Pollution
Decarbonizing shipping has become a critical necessity to combat climate change and address the air and water pollution caused by maritime transportation, which contributes significantly to global greenhouse gas emissions. Policy options for shipping decarbonization have been explored, emphasizing California's crucial role. Technological options like ammonia and methanol fuels, derived from green hydrogen, are considered for future ships.
Challenges and Uncertainty Surrounding Consensus on Decarbonizing Shipping
In the shipping industry, there isn't a clear consensus on how to eliminate emissions, with a variety of potential options like ammonia and methanol emerging as alternatives to traditional bunker fuels. The transition to new fuels faces uncertainty due to high costs, risks of stranded assets, and operational complexities on vessels.
Biofuels as a Potential Solution for Initial Decarbonization in Shipping
Biofuels have gained momentum in the shipping industry as an initial step towards decarbonization, offering some reductions in emissions. However, challenges such as fuel availability and operational differences exist between biofuels like renewable diesel and biodiesel. While biofuels may reduce emissions, they are not seen as the sole pathway to achieving complete decarbonization in shipping.
Electric Drivetrains and Renewable Energy Integration for Shipping Decarbonization
The adoption of electric drivetrains in shipping is gradually increasing, offering potential for reduced emissions. The use of renewable energy sources like offshore wind to power ships and ports plays a significant role in the long-term decarbonization efforts. However, challenges related to energy storage and operational scalability remain for larger ocean-going vessels.
Policy Measures and Industry Support Driving Decarbonization in Shipping
Strong policy measures and industry support are driving the decarbonization efforts in the shipping sector, with initiatives such as the International Maritime Organization setting targets for emission reductions. Countries like the US and California are urged to implement policies encouraging the shift to low-carbon fuels and investing in green hydrogen production for future shipping sustainability.
In this episode, David Wooley and Ed Carr, lead authors of recent papers outlining policy and technology options for reducing emissions in the shipping industry, discuss the fuels (and batteries?) that could power ships of the future, the policies needed to move forward, and California's pivotal role.
