Jervois begins commissioning at Idaho Cobalt Operations; only cobalt mine in US

Green Car Congress

Jervois has commenced infill and expansion drilling at ICO from both surface and underground platforms to improve ICO’s resource model to be used for short and medium-term mining operations. The historical Sunshine cobalt resource is located a short traverse to the ICO mill and concentrator. Across 2022, Jervois has announced a US$4.8-million,

New version of Argonne lifecycle model for water footprint of biofuels now includes cellulosic feedstocks

Green Car Congress

of the online tool Water Assessment for Transportation Energy Resources ( WATER ) this week. This latest version of WATER allows, for the first time, biofuels manufacturers to analyze water consumption associated with use of cellulosic feedstocks such as residue left from lumber production and other wood-based resources.

University of Houston team demonstrates new efficient solar water-splitting catalyst for hydrogen production

Green Car Congress

Researchers from the University of Houston (UH) have developed a cobalt(II) oxide (CoO) nanocrystalline catalyst that can carry out overall water splitting with a solar-to-hydrogen efficiency of around 5%. The generation of hydrogen from water using sunlight could potentially form the basis of a clean and renewable source of energy.

Researchers demonstrate electrochemical synthesis of ammonia from air and water under mild conditions

Green Car Congress

Andrews have demonstrated that ammonia can be synthesized directly from air (instead of N 2 ) and H 2 O (instead of H 2 ) under a mild condition (room temperature, one atmosphere) with supplied electricity which can be obtained from renewable resources such as solar, wind or marine. —Lan et al.

Researchers produce hydrogen from water and charcoal mix at room temperature using laser pulses

Green Car Congress

Researchers at Wakayama University in Japan have produced a mixture of hydrogen and carbon monoxide gas by irradiating a mixture of carbon powder and distilled water with intense nanosecond laser pulses at room temperature.

New ionic liquid biomass pretreatment method eliminates need for enzymes, reduces water use

Green Car Congress

We’re then able to separate the pretreatment solution into two phases, a sugar-rich water phase for recovery and a lignin-rich ionic liquid phase for recycling. As an added bonus, our new pretreatment technique uses a lot less water than previous pretreatments. —Blake Simmons, corresponding author. —Blake Simmons.

Researchers demonstrate water splitting to generate hydrogen using ultra-small Si nanoparticles

Green Car Congress

The ultra-small particles react with water to generate hydrogen 1,000 times faster than bulk silicon, 100 times faster than previously reported Si structures, and 6 times faster than competing metal formulations. Water can also be split chemically using a substance that can be oxidized by water, such as aluminum or silicon, the authors notes.
