Can ammonia or wind propel carbon-free shipping?
Show Notes

In the race for decarbonization, the shipping industry faces major challenges. Fuel is cheap, almost half the price of gasoline. And, most ships last between 20-25 years, meaning that the turnover to cleaner shipping could take far longer than road transportation, where the average car is only 12 years old

But there is some wind in the sails of maritime decarbonization initiatives.

Maria Gallucci, a climate journalist with Canary Media, has spent the last 5 years investigating the challenges and opportunities of decreasing maritime emissions. She spoke with Climate Now about why it is so hard to decarbonize this sector, and the diversity of approaches that are being explored, with a focus on ammonia and wind-powered propulsion.
