Novel inexpensive cobalt-nickel electrode for efficient water and urea electrolysis; yolk-shell nanoparticles

Green Car Congress

Both half reactions of water electrolysis—hydrogen and oxygen evolution—are unfortunately slow and require a lot of power. The material can be used as either an anode or a cathode, and demonstrates high activity and stability in the production of hydrogen and oxygen in the electrolysis of water. Zhang, S.L., and Lou, X.W.

MAN presents hydrogen roadmap; use in fuel cells and combustion engines

Green Car Congress

When in use, fuel cells do not cause any climate-damaging emissions, as they only emit water vapor. Cooperation with universities is also planned. MAN plans to build prototype vehicles as early as next year in line with the currently ongoing development projects. MAN is testing both the use of a fuel cell and an H 2 combustion engine.

Researchers and industry present interim results of the MethanQuest project

Green Car Congress

All the technologies involved—from water electrolysis to CO 2 extraction and methanation—have been examined and enhanced. The picture shows the test bench with the single-cylinder engine at the Technical University of Munich. The MethanFuel group is researching into new processes for manufacturing methane out of renewables.

Researchers develop free-standing nanowire mesh for direct solar water-splitting to produce H2; new design for “artificial leaf”

Green Car Congress

The mesh with BiVO 4 nanowire photoanode for water oxidation and Rh-SrTiO 3 nanowire photocathode for water reduction produces hydrogen gas without an electron mediator. When immersed in water with visible light irradiation (? ? In the present study, we developed a new architecture for direct solar water-splitting.

S. Korean team develops highly efficient, long-lasting electrocatalyst to boost electrolytic hydrogen production

Green Car Congress

Conventional water electrolysis for the production of hydrogen faces technological challenges to improve the efficiency of the water-splitting reaction for the sluggish oxygen evolution reaction (OER). Oxygen and hydrogen are generated during a water electrolysis reaction (top right). Credit IBS.

Study finds twice as many cellulose fibers as microplastics in the Atlantic Ocean

Green Car Congress

A study by three French institutes—Ifremer, the University of Bordeaux and the IRD (a public research institution)—has found that the surface water of the Atlantic Ocean is twice as polluted by cellulose fibers as it is by microplastics. Cellulose fibers are present in virtually all the samples collected (92.5%
