Ionic liquid-enhanced solvent extraction for oil sands bitumen shows high recovery rates, less water use and no tailing water

Green Car Congress

Researchers from Tianjin University and the National Engineering Research Centre for Distillation Technology, Tianjin, China, report on the use of an ionic liquid (IL) with low viscosity to enhance bitumen recovery from oil sands by solvent extraction while reducing adverse impacts in the ACS journal Energy & Fuels. However, Li et al.

DOE FCTO selects 11 fuel cell incubator projects for up to $10M in awards; exploring alkaline exchange membrane FCs

Green Car Congress

An alternative is the alkaline environment of the AEMFC. An NREL report summarizing the 2011 Alkaline Membrane Fuel Cell Workshop noted that: In comparison with PEMFCs, AMFCs offer the advantage of avoiding Pt or Pt group metal (PGM) electrocatalysts, one of the primary limitations in the commercial deployment of fuel cells. …

Expansion of sugarcane crop in Brazil to areas previously occupied by crops or pastureland leads to local cooling

Green Car Congress

It does so by reflecting sunlight back into space and by lowering the temperature of the surrounding air as the plants “exhale” cooler water. They measured temperature, reflectivity (albedo), and evapotranspiration—the water loss from the soil and from plants as they exhale water vapor. —Greg Asner. Loarie, David B.
