CU-Boulder team develops more efficient isothermal solar-thermal water splitting technique for H2 production

Green Car Congress

A University of Colorado Boulder team has developed a new solar-thermal water-splitting (STWS) system for the efficient production of hydrogen. STWS cycles have long been recognized as a desirable means of generating hydrogen gas (H 2 ) from water and sunlight, the team notes. A paper on their work is published in the journal Science.

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

is well known that some higher plants can synthesize ammonia or its derivatives directly from air and water at room temperature. To the best of our knowledge, there is no report on artificial synthesis of ammonia direct from air and water. The ammonia produced by plants is normally directly used as fertilizer by the plants.

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.

Third-generation Golf BlueMotion concept lowers fuel consumption to 3.2 l/100 km (73.5 mpg US); on sale in summer 2013

Green Car Congress

This third generation Golf BlueMotion will be launched into the market in summer 2013. This Golf concept, powered by another new 1.6-liter liter TDI (turbodiesel) consumes 3.2 l/100 km (73.5 mpg US), equivalent to 85 gCO 2 /km. The 81 kW / 108 hp Golf BlueMotion is a five-seater that is capable of 202 km/h (125 mph). l/100 km (52.3

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.
