New composite reduces rare earth element usage in three-way catalytic converters

Green Car Congress

The high-performance, three-way catalytic (TWC) converter is one of the workhorses of emissions reduction for gasoline engines. This function is crucial in current TWC, in which the oxygen partial pressure in the exhaust must be regulated to be near the ideal air-to-fule ration (A/F = 14.6). —Machida et al. Click to enlarge.

Stena Line seeking novel approaches to recover energy from exhaust gases from ship engines

Green Car Congress

Stena Line is seeking novel, cost-effective approaches to recover energy from exhaust gases from ship engines and to transform it into a more useful energy form (e.g., The company is also interested in efficient turbine systems that generate electricity from the kinetic energy from the massflow and velocity of the exhaust gases.

BMW fitting all gasoline and PHEV models in Germany with particulate filters for Euro 6d-TEMP compliance

Green Car Congress

As of July 2018, all BMW gasoline and plug-in hybrid models available in Germany will be fitted as standard with a gasoline particulate filter (GPF) and thus will comply with the exhaust standard Euro 6d-TEMP. In addition, another 39 diesel models will be going on the market with Euro 6d-TEMP rating.

pre- and post- decarbonization of the electric power sector—to which he referred as pre-CCS and post-CCS, respectively (although decarbonization was not necessarily via CCS—carbon capture and storage).) Direct capture of CO 2 from air, or from an exhaust stream vented to the atmosphere, represents negative emissions.

Turboden to supply a 10 MW heat recovery ORC unit for Arvedi steel plant in Italy

Green Car Congress

MW for the first years, will convert the off-gas waste heat from the steel-melting Electric Arc Furnace (EAF) to electric power. The heat recovery system configuration includes a saturated steam heat carrier circuit to convey the heat from the furnace exhaust gas to the ORC unit. MW unit for ORI Martin in Italy.

EPA Proposes to Streamline Approval Process for Fuel Conversion Systems

Green Car Congress

The new options would reduce some economic and procedural impediments to clean alternative fuel conversions while maintaining environmental safeguards to ensure that acceptable emission levels from converted vehicles are sustained. EPA expects the streamlined approach to result in a cost savings for many converters. Intermediate age.
