Summary

While aviation may be converging on one main pathway to decarbonization — sustainable aviation fuel — maritime shipping may require a more diverse set of solutions: a portfolio of fuels, energy efficiency, and on-board carbon capture and storage. But each technology has operational and capital challenges. So what will it take to scale them up? In this episode, Shayle talks to Dr. Lynn Loo, CEO of the Global Centre for Maritime Decarbonisation. Ocean-going shipping consumes about 300 million tons of fuel per year, accounting for 3% of global emissions. But with significant regulatory pressure from bodies like the International Maritime Organization, shipping companies are exploring a range of options. Shayle and Lynn cover topics like: Conventional fuels, like heavy fuel oil and marine gas oil The inadvertent climate impact of cutting sulfur emissions The pros and cons of lower-carbon fuels, like LNG, biofuels, methanol, and ammonia The challenges for infrastructure and operations, especially involving the low volumetric energy density of new fuels On-board carbon capture and storage How energy efficiency reduces the impact of low volumetric energy density Recommended resources International Maritime Organization: Fourth Greenhouse Gas Study 2020 Catalyst: Heavy duty decarbonization Catalyst: Putting a halt to geoengineering — by accident Catalyst is brought to you by Anza Renewables, a data, technology, and services platform for solar and storage buyers.
