Berkeley researchers propose salted biomass as scalable, economical and stable carbon capture and storage solution

Green Car Congress

Researchers from the University of California, Berkeley, are proposing burying salted biomass in a dry environment within an engineered biolandfill as a solution to sequester carbon that has been photosynthetically fixed by cultivated plants. This is measured by “water activity,” a quantity similar to relative humidity. In 1 y, PNAS.

Sandia team puts power into local grid with supercritical CO2 closed-loop Brayton-cycle turbine

Green Car Congress

The system uses heated supercritical carbon dioxide instead of steam to generate electricity and is based on a closed-loop Brayton cycle. Supercritical carbon dioxide is a non-toxic, stable material that is under so much pressure it acts like both a liquid and a gas. Graphic courtesy Sandia National Laboratories).

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. The carbon or charcoal powders were dispersed in distilled water at a ratio of 25.8

Study: Energy sorghum may combine best of annual, perennial bioenergy crops

Green Car Congress

Now, a study by researchers at the US Department of Energy (DOE) Center for Advanced Bioenergy and Bioproducts Innovation (CABBI) has found that energy sorghum ( Sorghum bicolor ) behaves more like miscanthus in the way it efficiently captures light and uses water to produce abundant biomass. Energy sorghum falls somewhere in between.

LBNL, Nissan researchers explore ethanol internal reforming in SOFCs for vehicle applications

Green Car Congress

The e-Bio Fuel Cell system featured an an SOFC stack and an on-board reformer to convert 100% ethanol or ethanol-blended water (55% water, 45% ethanol) to hydrogen. Dilution of ethanol with water increases safety, and is expected to suppress anode coking by increasing the steam-to-carbon ratio. … Earlier post.)

RENK supplies special gear units for compressors for production of green steel

Green Car Congress

Just for comparison, the engine speed of a passenger car in normal driving is a maximum of 2,000 to 3,000 revolutions per minute. In direct reduction, iron ore is converted into sponge iron with the help of a reducing agent. Instead of CO 2 , this technology produces water, which in turn is reused in the integrated process.

VW’s 1.0 TSI in the new up! GTI wins International Engine of the Year 2018 award in its category; Euro 6d-TEMP

Green Car Congress

The 85 kW / 115 PS gasoline-fired engine is the first of its kind to be combined with a four-way catalytic converter and installed in the up! As a comparison point, in 1976, the first Golf GTI delivered 140 N·m at 5,000 rpm.) Due to its special coating, it works in parallel as a regular catalytic converter.
