Technology group Wärtsilä has launched its pioneering carbon-free hydrogen and ammonia test programme which will assess the fuels potential for viable in the company’s fuel-flexible combustion engines.
Tests have already been conducted on hydrogen ammonia blends, as well as pure hydrogen, with one test engine performing “very well” when running a fuel with 70% ammonia content at a typical marine load range.
In order to help with the company’s transition to a decarbonised future, Wärtsilä intend for testing to continue throughout the coming years with the goal of defining the most feasible internal combustion engine-based solutions for power plant and marine applications.
Various timelines are to be explored by Wärtsilä according to each market. For the energy market, the company plan for an engine and plant concept for pure hydrogen operation to be ready by 2025. For the marine market, it expects to have an engine running on an ammonia blend already this year, with a pure ammonia powered engine concept being anticipated in 2023. Although some distance away, it is anticipated that, within the energy market, 7% of the global energy demand will be delivered by green hydrogen by 2050.
