Wärtsilä expands methane slip reduction capabilities by introducing NextDF technology

Technology group Wärtsilä has introduced its NextDF technology for a third engine, the Wärtsilä 46TS-DF dual-fuel engine. While operating on liquefied natural gas (LNG), the Wärtsilä 46TS-DF engine with NextDF feature reduces methane emissions to less than 1.4 percent of fuel use across all load points, achieving as low as 1.1 percent in a wide

Methane-Fuelled ME-GI engines continue to lead way with lowest methane slip

Times Shipbuilding Co. Ltd. of Jiangsu province, China has ordered 12 × 8G95ME-GI (-Gas Injection) Mk10.5 main engines in connection with the construction of 12 × 18,000 teu container vessels for Eastern Pacific Shipping (EPS), the Singapore-based shipping company. Bjarne Foldager – Country Manager, Denmark – MAN Energy Solutions, said: “This new, sizable order reflects the

Methane slip from ships back in the focus

Likely grabbing the most headlines is an 80-page report from the Washington DC-based International Council on Clean Transportation (ICCT) which claims real-world methane emissions from LNG-fuelled ships are higher than current regulations assume. Policymakers have been urged to consider increasing the default methane slip value to at least 6% for the most common LNG engine

Rotoboost gets LR’s nod for pre-combustion CCS

Lloyd’s Register (LR) has awarded Approval in Principle (AiP) to Rotoboost, a Nordic hydrogen production company, for its pre-combustion Carbon Capture System (CCS) Rotobox. Rotobox uses thermocatalytic decomposition process (TCD) onboard marine vessels, where part of the natural gas fuel supply is converted into hydrogen and graphite with a liquid catalyst. The TCD process significantly

Wärtsilä and Shell to work on methane slip project

Wärtsilä is part of a consortium that has secured European Union funding to develop solutions minimizing methane slip from marine engines. The project, called Green Ray, will develop on-engine technologies for low-pressure dual-fuel engines – both 2- and 4-stroke – as well as a novel aftertreatment concept. These solutions will be advanced to a high

Study at sea on methane slip commences

A new joint project will use onboard techniques and drones to measure methane emissions from ships. The International Council on Clean Transportation (ICCT) is leading the project called FUgitive Methane Emissions from Ships (FUMES), in collaboration with Danish-based Explicit and the Netherlands Organization for Applied Scientific Research (TNO). Using in-stack continuous emissions monitoring, drones, and
