Reducing greenhouse gas emissions

In addition to improving the efficiency of its solutions, Wärtsilä continuously develops technologies for reducing greenhouse gas linked emissions from both diesel and gas engines. The most important of such emissions are carbon dioxide (CO2) and methane (CH4). Wärtsilä has put significant emphasis on the research and development of gas engine technology and as a result is a world leader in this field. For gas engines, Wärtsilä is developing technologies such as Ultra Low THC (Total Hydro Carbons) emission reduction, which reduces the THC levels by 30-90% by utilising both primary and secondary technologies.

By the end of 2012 many benefits have materialised and especially at low load the methane slip is reduced by as much as 75%.

Many of the engine optimisations can also be retrofitted on existing older engines. These measures can include optimising combustion space, updating the software that is controlling the combustion, and a general optimisation of the machinery power management.
