Ammonia attracts the shipping industry, but researchers warn of its risks

Switching to ammonia as a marine fuel, with the goal of decarbonization, can instead create entirely new problems. This is shown in a study from Chalmers University of Technology in Sweden, where researchers carried out life cycle analyses for batteries and for three electrofuels including ammonia. Eutrophication and acidification are some of the environmental problems that can be traced to the use of ammonia—as well as emissions of laughing gas, which is a very potent greenhouse gas.
