Pitt engineers using membrane distillation to recycle water used in fracking and drilling

Green Car Congress

Engineers at the University of Pittsburgh Swanson School of Engineering are using membrane distillation technology to enable drillers to filter and reuse the produced water in the oil and gas industry, in agriculture, and other beneficial uses. The method is already being tested in Texas, North Dakota, and most recently in New Stanton, Pa.

As Tesla waits for Giga Berlin’s final approval, critics reiterate water supply concerns

Teslarati

With the massive factory still awaiting its final approval, some of Giga Berlin’s critics have reiterated concerns about the electric vehicle factory’s water consumption. Elon Musk has been asked about Giga Berlin’s water consumption in the past. The factory just is not a very intense consumer of water per square meter. “The

Argonne analysis shows greenhouse gas emissions similar for shale, conventional oil

Green Car Congress

Shale oil production generates greenhouse gas emissions at levels similar to conventional crude oil production, according to a pair of new studies released by the US Department of Energy’s Argonne National Laboratory. Until now, little information has existed about how production methods impact greenhouse gas emissions at these sites.

Dow Planning to Build and Operate a Pilot-Scale Algae-to-Ethanol Biorefinery with Algenol Biofuels

Green Car Congress

to build and operate a pilot-scale algae-based integrated biorefinery that will produce ethanol, located at Dow’s Freeport, Texas site. The Direct to Ethanol process links sugar production to photosynthesis with naturally occuring enzymes within individual algae cells. By comparison, corn produces around 400 gallons/acre/year.

New Method for Producing High-Performance Zeolite Membranes; Could Increase Energy Efficiency of Biofuel Production

Green Car Congress

Engineers have developed a new method for creating high-performance membranes from zeolites; the method could increase the energy efficiency of chemical separations up to 50 times over conventional methods and enable higher production rates. Where possible, repairing the zeolite membrane is difficult and expensive.
