Wärtsilä dual-fuel engines to power four new LNG carriers

October 20, 2017

The technology group Wärtsilä, through its joint venture company CSSC Wärtsilä Engine (Shanghai) Co (CWEC), has been contracted to deliver 16 engines for four new LNG carrier vessels being built at the Hudong Zhonghua shipyard in China. The order was booked in August 2017.

Each of the four 174,000 m3 capacity vessels will be fitted with four Wärtsilä 34DF dual-fuel generating sets running primarily on LNG fuel to provide the ships with auxiliary power. Their total power output will be 56 MW. Among the reasons given for the Wärtsilä 34DF engine being chosen for these ships were its proven reliability, efficiency, and economic fuel consumption. Delivery of the engines to the yard will commence in the second half of 2018. The vessels are scheduled to be delivered commencing in 2019.

Wärtsilä installs first hybrid energy storage solution on LNG-fueled offshore supply ship

October 16, 2017

The technology group Wärtsilä has completed the installation of a hybrid energy system on board Viking Princess. (Earlier post.) The Norwegian vessel is now the first offshore supply vessel in which batteries reduce the number of generators aboard the ship.

The new energy storage solution will improve engine efficiency, generate fuel savings and reduce greenhouse gas emissions. Viking Princess completed sea trials and the system was handed over to customer Eidesvik Offshore on 9 October 2017.

Wärtsilä to acquire biogas upgrader Puregas Solutions

October 06, 2017

The technology group Wärtsilä has reached an agreement to acquire Puregas Solutions, a Sweden-based provider of turnkey biogas upgrading solutions. Puregas is a leading player in its field with subsidiary companies in Germany, Denmark, the UK, and the US. The company utilizes a unique CApure process to convert raw biogas to biomethane and renewable natural gas.

The CApure process recovers more than 99.9% of the biomethane present in the raw biogas. The process separates the CO2 from the biogas by a process of chemical adsorption. The selective organic solvents used in this process are so efficient that the end product can contain more than 99% methane and is suitable for vehicle fuel or to be injected into the natural gas grid.

New Euro6 trucks from Volvo running on LNG offer the same performance as diesel, but with 20-100% lower CO₂ emissions

October 04, 2017

Volvo Trucks is now introducing Euro 6-compliant heavy duty trucks running on liquefied natural gas or biogas. The new trucks have the same performance, driveability and fuel consumption as Volvo’s diesel-powered models. Furthermore, the new trucks’ CO₂ emissions are 20–100% lower compared with diesel, depending on choice of fuel. The new Volvo FH LNG and Volvo FM LNG are available with 420 or 460 hp for heavy regional and long-haul operations.

Instead of an Otto cycle engine, which is the conventional solution for gas-powered vehicles, the Volvo FH LNG and Volvo FM LNG are powered by gas engines utilizing Diesel cycle technology. This means that an operator who chooses gas can do so without compromising on driveability, fuel efficiency or reliability. Volvo’s 460 hp gas engine delivers maximum torque of 2300 N·m while the 420 hp version produces 2100 N·m. This is the same as Volvo’s corresponding diesel engines. Fuel consumption is on a par with Volvo’s diesel engines, but 15 to 25% lower than for conventional gas engines.

Volvo Trucks intensifying development of LNG trucks for heavy regional and long-haul transport operations

September 27, 2017

Volvo Trucks is taking the position that by replacing diesel with liquefied natural gas or biogas, CO2 emissions from heavy trucks can be drastically reduced. Volvo Trucks is intensifying its development of gas-powered trucks for heavy regional and long-haul operations.

Reducing climate-impacting emissions from heavy commercial traffic is a challenge that engages politicians and transport purchasers, haulage companies and vehicle manufacturers. In May the EU presented a regulation demanding declaration of CO2 figures from heavy vehicles as of 2019, with the aim of reducing CO2 emissions.

New German LNG-fueled research ship will feature Wärtsilä technology

August 05, 2017

Wärtsilä will supply dual-fuel engines for a new LNG-fueled research vessel being built for the German government. Wärtsilä will also supply exhaust cleaning systems based on selective catalytic reduction (SCR) technology and the LNGPac system for complete fuel gas handling.

The SCR technology will be needed when the engines are running on conventional marine diesel fuel if the vessel exhausts its supply of LNG on long voyages. The vessel is under construction at the Fassmer shipyard in Germany and will be owned by Bundesamt für Seeschifffahrt und Hydrographie (BSH), the Federal Maritime and Hydrographic Agency. The contract was signed with Wärtsilä in June 2017.

Fiat Chrysler Automobiles, IVECO and ENGIE collaborating to promote natural gas in Europe starting from Belgium

January 25, 2017

Fiat Chrysler Automobiles (FCA), IVECO (a brand of CNH Industrial) and ENGIE (Global Energy Player) are broadly collaborating to promote natural gas vehicles and infrastructure in Europe. This collaboration is in line with the implementation of the DAFI Directive (Directive 2014/94 - Deployment of Alternative Fuels Infrastructures), with a particular focus on certain countries and regions, starting from Wallonia, Belgium.

At the “Salon de l’Auto” in Brussels, the Minister of Mobility and Environment announced a program for the improvement of air quality in Wallonia. In line with COP 21, the Walloon strategy envisages that 50% of its public fleet vehicles, in need of replacement, will run on alternative fuels starting from 1 January 2017, and the percentage will rise to 100% starting from 1 January 2030. The Government of Wallonia also set a new regulation to promote the development of CNG infrastructure.

Cummins Westport ISB6.7 G midrange natural gas engine now in full production

December 09, 2016

Cummins Westport’s ISB6.7 G, a 6.7 liter midrange, factory-built natural gas engine is now fully available as a production engine for shuttle bus, medium duty truck, and vocational applications in North America. (Earlier post.) As previously announced, the engine has been available for school bus applications since May 2016 from Thomas Built Buses. The 6.7 liter engine platform has large OEM availability for midrange trucks, vocational trucks and mid size buses and the expansion of applications potentially available for the ISB6.7 G engine more than doubles its addressable market.

The ISB6.7 G is based on the Cummins ISB6.7 diesel engine platform, the industry leader in the Cummins midrange engine family, and operates exclusively on natural gas, including compressed, liquid, or renewable natural gas (RNG). The ISB6.7 G is the second engine from Cummins Westport (CWI) to receive emission certification from the US Environmental Protection Agency (EPA) and the Air Resources Board (ARB) in California for meeting the Optional Low NOx Emissions standards.
