Solutions for reducing greenhouse gas emissions

Wärtsilä is continuously developing new technologies and upgrading existing ones in order to limit emissions of harmful greenhouse gases (GHG) into the atmosphere. This is achieved not only through the development of gas and dual-fuel engine technologies, but also through its industry leading developments in hybrid/electric propulsion for ships, and a broad portfolio of exhaust gas cleaning systems for vessels running on conventional marine fuels. 

Some of Wärtsilä's many solutions for reducing greenhouse gas emissions include: 

Gas and multifuel engines
The Wärtsilä dual-fuel (DF) engines are used in power plants and for powering a wide range of different kind of vessels. Wärtsilä is continuously developing its portfolio of gas and multi-fuel engines to offer high efficiency, low exhaust gas emissions and safe operation. The fuel flexibility of Wärtsilä's gas engine technology facilitates efforts by both the marine and power sectors to move towards zero greenhouse gas emissions.

Modernisations and conversion services
Wärtsilä applies new technologies also to its existing products, which makes it possible to further reduce their environmental impact. With the help of our service products, we can improve the efficiency of older engines and reduce their emissions to the same level as those of our newer products. We also convert oil-fuelled engines for gas or biofuel use. 

Environmentally advanced vessel solutions
The Wärtsilä Gas Platform Supply Vessel (PSV) design features outstanding energy efficiency, an optimised hull design, lower fuel consumption, reduced fuel costs, and fewer exhaust emissions compared to vessels running on conventional marine fuel. The Wärtsilä HY is a hybrid power module that combines engines, an energy storage system, and power electronics optimised to work together through a newly developed energy management system. When operating in ‘Green Mode’ zero emissions can be achieved.

VER interior
Gas recovery solutions for the oil & gas segments 
Wärtsilä VOC recovery system for onboard floating storage units and shuttle tankers is self supplied with energy and results in zero volatile organic compounds (VOC) emissions. The Wärtsilä Voyage Emissions Reduction (VER) effectively eliminates the problem of VOC emissions from tankers during laden voyages. A reduction of 5400 tons of VOC per year translates to approximately 20,000 tons COequivalents. Local pollution is reduced by 80%.

Voyage optimisation solutions provided by Wärtsilä companies
Eniram provides the maritime industry with energy management technology to reduce fuel consumption and emissions. Solutions range from single onboard applications for trim, speed and engine optimisation to comprehensive fleet analysis. Transas offers marine navigation solutions, professional training and simulation services, ship traffic control, as well as monitoring and support. Transas solutions provide the most efficient voyage plans with minimal fuel consumption and CO2 emissions based on advanced mathematical models.

Combined cycle 
Wärtsilä FlexicycleTM power plants integrate an engine power plant, heat recovery system and steam turbine to improve power plant efficiency and reduce emissions. Dry Flexicycle is a concept that combines all the benefits of Flexicycle technology with drastically reduced water requirements, making in the right choice for arid areas.

Combined heat and power & trigeneration
Combined heat and power (CHP) and trigeneration (power, heat and cooling) plants use fuel in the most efficient way and at the same time help to reduce carbon dioxide emissions. Total plant efficiencies can reach over 90% depending on the application. Wärtsilä’s CHP plants can run on various liquid, gaseous and bio fuels, while maintaining low emissions and high efficiency. 

Energy storage software platform
Greensmith, a Wärtsilä company, offers an industry-leading energy software platform system GEMS. With GEMS, hybrid power plants run in an optimal way at all times ensuring ideal utilization of both the engines and the energy storage solution to enable instant power while saving fuel, maintenance costs and reducing emissions.
