Ahead of London International Shipping Week 2021, a six-part S&P Global Platts podcast miniseries looks into the pricing of alternative marine fuels for the global shipping industry. In each episode of Marine Fuels of the Future, Platts editors investigate the current state of the major fuel alternatives, as the shipping sector seeks to reduce its greenhouse gas emissions ahead of stringent caps in 2030 and 2050. In episode five, Platts energy transition reporters look at the practical and economic complexities of using ammonia or hydrogen to power the fleet.
