New photochemical diode artificial photosynthesis system doubles efficiency of solar water splitting

Green Car Congress

Researchers in Canada have demonstrated a new photochemical diode artificial photosynthesis system that can enable efficient, unassisted overall pure water splitting without using any sacrificial reagent. overall water splitting reaction. These free charges split water molecules into hydrogen and oxygen. … in neutral (pH?~?7.0)

New catalysts enable photocatalytic version of water gas shift reaction for H2 production

Green Car Congress

Politécnica de Valencia (Spain) have found that noble metal nanoparticles supported on titanium dioxide or cerium dioxide can catalyze the industrially important water gas shift (WGS) reaction for hydrogen production at ambient temperatures using visible light irradiation. Catalysts Hydrogen Production Solar' Energy Environ.

Heating Buildings With Solar Energy Stored in Sand

Cars That Think

This sponsored article is brought to you by COMSOL. In a region known for long, dark winter nights, Polar Night Energy is building a system in the city of Tampere that can heat buildings with stored solar energy — all day, all night, and all winter long. The apparent contradictions do not end there.

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. tons of CO 2 is released per ton of ammonia produced.

Pilot Project Sends Kelp–and Carbon–to the Seafloor

Cars That Think

Last January, in the waters off Cebu City in the Philippines, researchers first deployed a huge flexible ring seeded with seaweed and spanned by spokelike ropes and tubes. Every nightfall, cranks mounted on a floating platform lower the ring 25 meters below the surface to expose the seaweed to cooler, more nutrient-rich water.

Sandia team boosts hydrogen production activity by molybdenum disulfide four-fold; low-cost catalyst for solar-driven water splitting

Green Car Congress

The improved catalyst has already released four times the amount of hydrogen ever produced by MoS 2 from water. You have to basically understand the material before you can move forward in changing industrial use. Kaehr cautions that what’s been established is a fundamental proof of principle, not an industrial process.

Kolhapur has potential to be auto component mfg hub: Gadkari – ET Auto

Baua Electric

Union road transport minister Nitin Gadkari on Saturday said Kolhapur had the potential to become a hub for manufacturing automobile components and that govt was looking to turn the ethanol industry into a INR 2-lakh-crore sector. Kolhapur is home to sugar mills and we are going to make the ethanol industry a INR 2-lakh-crore sector.
