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

New stable water-splitting catalyst doesn’t require expensive iridium

Green Car Congress

Researchers have developed a nickel-stabilized, ruthenium dioxide (Ni-RuO 2 ) anode catalyst for proton exchange membrane (PEM) water electrolysis. The Ni-RuO 2 catalyst shows high activity and durability in acidic OER for PEM water electrolysis. Illustration by Zhen-Yu Wu. 2 , suggesting potential for practical applications.

Leclanché reduces cobalt in NMCA cells from 20 to 5%; 20% higher energy density; water-based production

Green Car Congress

Leclanché SA has reduced the cobalt content in NMCA as cathode material from 20% to 5% and manufacture the electrodes using an environmentally friendly water-based process. In doing so, Leclanché completely dispenses the use of the highly toxic organic solvents (NMP) that are otherwise common in the production process.

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.

Cambridge study finds globalized economy making water, energy and land insecurity worse

Green Car Congress

The first large-scale study of the risks that countries face from dependence on water, energy and land resources has found that globalization may be decreasing, rather than increasing, the security of global supply chains. Countries meet their needs for goods and services through domestic production and international trade.
