Researchers split seawater without pre-treatment to produce green hydrogen

Green Car Congress

The use of vast amounts of high-purity water for hydrogen production may aggravate the shortage of freshwater resources. This is achieved by introducing a Lewis acid layer (for example, Cr 2 O 3 ) on transition metal oxide catalysts to dynamically split water molecules and capture hydroxyl anions.

DOE awarding $35M to 11 projects for hydrokinetic turbine development; ARPA-E SHARKS

Green Car Congress

Projects are encouraged to apply concurrent (as opposed to sequential) design methodologies: control co-design, co-design, and designing for operation and maintenance. HydroMINE is safe for the marine environment, and extremely robust. It has a low maintenance cost, resulting in a lower cost of energy. University of Washington.

Study links deterioration of concrete and asphalt to trace quantities of organic matter; diesel exhaust, windshield washer fluids

Green Car Congress

These deteriorated structures are unsafe for their intended purposes; rapid deterioration reduces the expected lifespan of structures, thereby increasing the costs for maintenance or replacement. During their experiments, the scientists happened to notice that a strange odor developed when commercial cement was mixed with water.

Eni and RenOils to boost collection of used cooking oil for biofuel production

Green Car Congress

The majority comes from homes, and goes down the drain for the most part, since most people don’t know that using the sewage network to dispose of cooking oil can have serious consequences for the environment. If it ends up in water, it forms a film that prevents the passage of sunlight, causing huge damage to the environment.
