Stanford researchers make ammonia from air and water microdroplets

Green Car Congress

Stanford researchers, with a colleague from King Fahd University of Petroleum and Minerals, have developed a simple and environmentally sound way to make ammonia with tiny droplets of water and nitrogen from the air. Water microdroplets are the hydrogen source for N 2 in contact with Fe 3 O 4. The conversion rate reaches 32.9 ± 1.38

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. The study was published in the journal Atmospheric Environment. This new study is based on a thorough review of a decade of research on aviation emissions.

Chalmers study finds ship exhaust gas scrubbers responsible for up to 9% of certain hazardous emissions into Baltic Sea

Green Car Congress

New research from Chalmers University of Technology, Sweden, finds that the discharge water from ships’ exhaust gas treatment systems—i.e., scrubbers—is responsible for up to 9% of certain emissions of carcinogenic and environmentally harmful substances in the Baltic Sea—considerably more than was previously known.

Monash study on solar-driven electrolysis for green hydrogen production cautions on life-cycle emissions and EROI

Green Car Congress

of hydrogen is currently produced via water electrolysis and only a fraction of this production is powered by renewable energy. The NWIS comprises mostly gas-fired generation and has a GHG emission factor of 620 g CO 2 -e kWh -1. The emissions factor of electricity for the solar module supply chain is a critical sensitivity.

Oleophobic hydrophobic magnetic sponge selectively soaks up oil, sparing water and wildlife

Green Car Congress

A Northwestern Engineering-led team has developed a highly porous smart sponge that selectively soaks up oil in water. Oil spill clean-up is an expensive and complicated process that often harms marine life and further damages the environment. Burning increases carbon emissions and dispersants are terribly harmful for marine wildlife.

How Keeping Your Tires Inflated Can Help the Environment

Clean Fleet Report

How Keeping Your Tires Inflated Can Help the Environment Basic Care Can Reduce Contamination Checking tire pressure is a subtle yet impactful way to care for the environment. Regulatory bodies have overseen vehicle emissions for years, while these other environmental concerns remain barely attended despite a tire’s composition.
