Wärtsilä initiates combustion trials using ammonia

In Sweden, Wärtsilä has initiated combustion trials using ammonia. The research will help the company to prepare for the use of ammonia as a fuel that can contribute to reducing both the shipping’s and energy sectors’ greenhouse gas emissions.

As part of the tests, ammonia was injected into a combustion research unit to better understand its properties. Based on initial results, the tests will be continued on both dual-fuel and spark-ignited gas engines. These will be followed by field tests in collaboration with ship owners from 2022, and potentially also with energy customers in the future.
