MIT and IEA reports take different views of the future of natural gas in transportation

Green Car Congress

While compressed natural gas (CNG) will play a role, particularly for high-mileage fleets, the report suggests that the chemical conversion of gas into some form of liquid fuel may be the best pathway to significant market penetration. emissions are reduced by around 25% relative to the use of gasoline for the same engine efficiency.

BMW provides an update on waste heat recovery projects; Turbosteamer and the Thermoelectric Generator

Green Car Congress

Finding ways of recovering this lost heat energy has been one of the major goals being pursued by engineers working on BMW EfficientDynamics for the future. The gas turbine process is the first phase of the energy conversion and serves as the source of heat for the downstream steam cycle in the second phase. —Jürgen Ringler.
