VWG Oldenburg acquires 15 MAN CNG hybrid buses; MAN Lion’s City 12 G with EfficientHybrid technology

Green Car Congress

The new buses have a crankshaft starter generator on board that converts braking recuperation energy into electrical energy. The intelligent energy management of the EfficientHybrid module uses the energy created through recuperation during braking and then stored in ultracaps to supply the on-board network.

Arizona State University Professor’s Work to Stabilize the Grid Pays Off

Cars That Think

He was part of an IEEE task force that in 2020 issued a report that described how equipment used for storing energy, transferring power over long distances, and integrating renewable energy could impact power system stability. These issues required a reevaluation of how we had defined and classified stability in 2004,” Vittal says.

Chrysler and EPA to partner on hydraulic series hybrid powertrain for light duty vehicles

Green Car Congress

The accumulators are used to store pressurized fluid. Acting as a pump, the hydraulic drive is used to re-pressurize hydraulic fluid by using the vehicle’s momentum, thereby converting kinetic energy into potential energy. Fluid for the system will be stored in a 14.4-gallon liter, inline four-cylinder gasoline engine.

Up close and personal with Volkswagen’s e-Golf carbon offset project: Garcia River Forest

Green Car Congress

Trees are natural carbon sinks; they absorb carbon dioxide by photosynthesis, some of which is stored as carbon compounds in the wood—both during growth and even after harvesting, in the form of some wood products. Underground, forest soils and root structures store even more carbon. Calculating stored carbon; “additionality”.

Recent Hybrid Braking Complaints Highlight Regenerative Braking Design Issues

Green Car Congress

Right: 2004-2009 Toyota Prius (THS-II). Likewise, a vehicle with a battery pack that happens to be near the upper range of its charge window (~70% to 80% for many hybrids) will also be limited in its ability to convert braking force to stored energy during a given braking event. Left: 2001-2003 Toyota Prius (THS).

Two Genomic Research Projects in British Columbia Tackle Issues in Emerging Forestry Biofuels Industry

Green Car Congress

Trees are a huge store of chemical energy that can be converted into liquid biofuel—but we need to identify the ideal method to produce these sugars economically. Jack Saddler, Dean of Forestry at the University of British Columbia, is leading a C$1.1-million million (US$1.0-million) million (US$7.2-million)
