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

Argonne study compares life cycle emissions of battery-grade lithium carbonate and lithium hydroxide from brines and ores

Green Car Congress

Researchers at Argonne National Laboratory have conducted life cycle analyses (LCAs) for battery-grade lithium carbonate (Li 2 CO 3 ) and lithium hydroxide monohydrate (LiOH•H 2 O) produced from Chilean brines (Salar de Atacama) and Australian spodumene ores. This information will help us achieve our goal of being carbon neutral by 2030.

A Bamboo Carbon Filter for Diesels Could Reduce Emissions

Cars That Think

Although the pollutant emissions of a diesel engine are less than those of a gasoline one, it still emits carcinogens, nitrous oxides, and soot. Older models don’t even have the emission-control features that newer ones do. To reduce emissions, diesel vehicles use filters that catch exhaust particles and other contaminants.

Study finds the wettability of porous electrode surfaces is key to making efficient water-splitting or carbon-capturing systems

Green Car Congress

As water-splitting technologies improve, often using porous electrode materials to provide greater surface areas for electrochemical reactions, their efficiency is often limited by the formation of bubbles that can block or clog the reactive surfaces. As a result, there were substantial changes of the transport overpotential. 2021.02.015.

Alcoa exploring technology to reduce carbon emissions in alumina refining; MVR powered by renewable energy

Green Car Congress

The development project has the potential to reduce carbon emissions in the alumina refining process significantly. In 2019, Australian alumina refining accounted for more than 14 million tonnes of carbon dioxide emissions, representing approximately 24% of Australia’s scope 1 manufacturing emissions.

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.
