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

GWU team demonstrates highly scalable, low-cost process for making carbon nanotube wools directly from CO2

Green Car Congress

Stuart Licht have demonstrated the first facile high-yield, low-energy synthesis of macroscopic length carbon nanotubes (CNTs)—carbon nanotube wool—from CO 2 using molten carbonate electrolysis ( earlier post ). The process is constrained by the (low) cost of electricity. —Johnson et al.

Stanford team reports new low-cost, non-precious metal catalyst for water splitting with performance close to platinum

Green Car Congress

Researchers at Stanford University, with colleagues at Oak Ridge National Laboratory and other institutions, have developed a nickel-based electrocatalyst for low-cost water-splitting for hydrogen production with performance close to that of much more expensive commercial platinum electrocatalysts. V with good stability.

BNL Researchers develop low-cost, efficient, non-noble metal electrocatalyst to produce hydrogen from water

Green Car Congress

James Muckerman at the US Department of Energy’s (DOE) Brookhaven National Laboratory (BNL) have developed a new class of high-activity, low-cost, non-noble metal electrocatalyst that generates hydrogen gas from water. The result becomes this well-balanced Goldilocks compound—just right. —James Muckerman.

Heliogen and Bloom Energy demonstrate production of low-cost green hydrogen; concentrated solar and high-temp electrolysis

Green Car Congress

Heliogen’s AI-enabled concentrated solar energy system is designed to create carbon-free steam, electricity, and heat from abundant and renewable sunlight. When combined with Bloom’s proprietary solid oxide, high-temperature electrolyzer, hydrogen can be produced 45% more efficiently than low-temperature PEM and alkaline electrolyzers.

Rice U team creates low-cost, high-efficiency integrated device for solar-driven water splitting; solar leaf

Green Car Congress

Rice University researchers have created an efficient, low-cost device that splits water to produce hydrogen fuel. The current flows to the catalysts that turn water into hydrogen and oxygen, with a sunlight-to-hydrogen efficiency as high as 6.7%. It utilizes water and sunlight to get chemical fuels.

Researchers use melamine to create effective, low-cost carbon capture; potential tailpipe application

Green Car Congress

Using an inexpensive polymer called melamine, researchers from UC Berkeley, Texas A&M and Stanford have created a cheap, easy and energy-efficient way to capture carbon dioxide from smokestacks. We distinguished ammonium carbamate pairs and a mix of ammonium carbamate and carbamic acid during carbon dioxide chemisorption.
