EU project HyFlexFuel converted sewage sludge and other biomasses into kerosene by hydrothermal liquefaction (HTL); SAF

Green Car Congress

The EU-funded research project HyFlexFuel recently successfully produced biocrudes via hydrothermal liquefaction (HTL) from a variety of biomasses, including sewage sludge, food waste, manure, wheat straw, corn stover, pine sawdust, miscanthus and microalgae in a pilot-scale continuous HTL plant at Aarhus University (Denmark).

Researchers provide insight into OER electrocatalyst

Green Car Congress

Researchers from Oregon State University College of Engineering, with colleagues from Cornell University and the Argonne National Laboratory, have used advanced experimental tools to provide a clearer understanding of an electrochemical catalytic process that’s cleaner and more sustainable than deriving hydrogen from natural gas.

Study Finds Stratospheric Water Vapor Is An Important Driver of Decadal Global Surface Climate Change

Green Car Congress

Decadal warming rates arising from (i) greenhouse gases and aerosols alone (black); (ii) that obtained including the stratospheric water decline after 2000 (red); and (iii) including both the stratospheric water vapor decline after 2000 and the increase in the 1980s and 1990s (cyan). Stratospheric water vapor and radiative processes.

A Roomba for Rivers

Cars That Think

Humankind is enamored with water. But few localities have the resources or political will to pay for cleanup costs. University of Washington has designed tiny sensors that mimic the shape and aerodynamic capability of the dandelion’s fuzzy, seed-bearing spores.

Purdue, EPFL team propose Hydricity concept for integrated co-production of H2 and electricity from solar thermal energy

Green Car Congress

Researchers from Purdue University and École Polytechnique FĂ©dĂ©rale de Lausanne (EPFL) in Switzerland are proposing a new integrated process involving the co-production of hydrogen and electricity from solar thermal energy—a concept they label “hydricity”. Emre Gençer, Dharik S. 1513488112.

Discovery of mechanism for atmospheric particle formation suggests need for ammonia emission regulations

Green Car Congress

Scientists from the Karlsruhe Institute of Technology (Germany), University of Colorado Boulder, and Universidad Nacional Autónoma de México performed a “CT Scan” of the atmosphere, moving along latitudes and longitudes, measuring particle concentrations and compositions in the upper troposphere.

MUCHACHAS study finds aging of organic aerosols is caused by OH radicals; climate models need to be updated

Green Car Congress

Aerosols are also essential for cloud formation in the troposphere: They act as condensation nuclei which even in the presence of low levels of water vapor do enable droplets to form. —Professor Dr. Thorsten Hoffmann of the Institute of Inorganic Chemistry and Analytical Chemistry at Johannes Gutenberg University Mainz (JGU).
