Volkswagen 2.0 TDI diesel for Euro 6d; SCR twin-dosing

Green Car Congress

With SCR twin dosing technology in the exhaust gas system, the diesel unit now undercuts the Euro 6d emission standard limits while also running quietly and smoothly, according to the company. The four-cylinder TDI engine with the internal designation EA 288 made its debut in 2012. As previously, the 2.0

HyMethShip seeks to fuel ship engines with hydrogen from methanol

Green Car Congress

In this concept, the ship is refueled with methanol at port. The methanol is mixed with water, then evaporated by applying heat and fed into the preheated reactor, where the mix of methanol and water is converted into hydrogen and CO 2. The system’s technical centerpiece is the reactor. © Fraunhofer.

EPFL team develops on-board system to capture CO2 from trucks; reducing emissions by 90%

Green Car Congress

Researchers at EPFL have patented a new concept that could cut trucks’ CO 2 emissions by almost 90%. The EPFL system captures CO 2 directly in the trucks’ exhaust system and liquefies it in a box on the vehicle’s roof. The patented concept is the subject of an open-access paper published in Frontiers in Energy Research.

Alfa Laval introduces E-PowerPack ORC waste heat recovery system for ships

Green Car Congress

In a typical ORC design, a thermal energy source feeds an evaporator to drive an expander or “reverse compressor”, which in turn generates the electricity. Basic ORC concept. Where heat pumps use electrical power to create thermal energy for various purposes, an ORC system uses heat energy to generate electricity.

New fuel-efficient bulk carrier concept design; DNV estimates new tankers, bulkers and container vessels will be up to 30% more energy efficient by 2020 than newbuilds today

Green Car Congress

The Shanghai Merchant Ship Design & Research Institute (SDARI) and development partners DNV and Wärtsilä have unveiled a new Handysize—i.e., ships with a cargo-carrying capability of less than 60,000 metric tonnes—bulk carrier concept design: the Green Dolphin. Draught, design. Speed at design draught.
