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.

Researchers produce hydrogen from water and charcoal mix at room temperature using laser pulses

Green Car Congress

Researchers at Wakayama University in Japan have produced a mixture of hydrogen and carbon monoxide gas by irradiating a mixture of carbon powder and distilled water with intense nanosecond laser pulses at room temperature. Photographs of a bottled mixture of Bincho-tan powder and water (a) before, (b) during, and (c) after irradiation.

New liquid hydrogen carrier would transport green H2 from Scotland to Germany

Green Car Congress

As a comparison, LNG tankers use ballast water to compensate the loss of weight following delivery to ensure enough draft. The limited remaining boil off will be captured and directly utilized in hydrogen fuel cells, providing power to the vessel's propulsion systems, resulting in emissions of water only. Vessel specifications.

Review of co-processing of biocrudes in oil refineries

Green Car Congress

The major compound groups in FPBO are water (20–25 wt %), carboxylic acids (∼ 5 wt %), aldehydes, ketones, and furfurals (25 wt %), sugar-like material (30–35 wt %), and lignin-derived compounds (20 wt %). In HTL, wet feedstock is liquefied in a hot (250–374 °C) and pressurized (4–22 MPa) water environment into biocrude oil.
