Novel inexpensive cobalt-nickel electrode for efficient water and urea electrolysis; yolk-shell nanoparticles

Green Car Congress

Electrolytic hydrogen production powered by renewable energy is seen as an environmentally friendly means to ameliorate global climate and energy problems. Both half reactions of water electrolysis—hydrogen and oxygen evolution—are unfortunately slow and require a lot of power. Zhang, S.L., and Lou, X.W.

Study: 2/3 of aviation climate impact due to emissions other than CO2

Green Car Congress

of the human-made climate impact; two-thirds of this impact are caused by emissions other than CO 2 , according to a new study by researchers in Europe and the US. Schematic overview of the processes by which aviation emissions and increased cirrus cloudiness affect the climate system. Aviation accounts for 3.5% —Lee et al.

Rolls-Royce and Robert Allan present world’s first LNG-powered shallow-water push boat

Green Car Congress

Rolls-Royce and Canadian vessel designers Robert Allan have developed the world’s first shallow-water push boat powered by LNG natural gas engines. LNG (liquefied natural gas) is gaining traction in maritime circles, enabling operators to reduce emissions that are harmful to the environment and to the climate.

MAN presents hydrogen roadmap; use in fuel cells and combustion engines

Green Car Congress

When in use, fuel cells do not cause any climate-damaging emissions, as they only emit water vapor. MAN plans to build prototype vehicles as early as next year in line with the currently ongoing development projects. MAN is testing both the use of a fuel cell and an H 2 combustion engine.

DLR: cleaner aircraft emissions reduce the climate impact of contrail cirrus

Green Car Congress

Fewer soot particles in the exhaust stream of aircraft reduces the formation of ice crystals and therefore the climate impact of the resulting contrail cirrus. The results are published in an open-access paper in the Nature Partner Journal (npj) Climate and Atmospheric Science. Burkhardt et al. —Ulrike Burkhardt.

EU researchers develop innovative energy-efficient climate control system for electric vehicles; XERIC

Green Car Congress

EU-funded researchers have developed an innovative climate control system (CCS) that extends the range of electric vehicles while enhancing passenger comfort. At present a substantial amount of energy is required to run the CCS within electric vehicles, creating a major drain on the battery and limiting the range of the car.

Study projects thermoelectric power in Europe and US vulnerable to climate change due to lower summer river flows and higher river water temperatures

Green Car Congress

A study published in Nature Climate Change suggests that thermoelectric power plants (i.e., nuclear and fossil-fueled generating units) in Europe and the United States are vulnerable to climate change due to the combined impacts of lower summer river flows and higher river water temperatures. 19% in Europe and 4.4—16%
