Oleophobic hydrophobic magnetic sponge selectively soaks up oil, sparing water and wildlife

Green Car Congress

A Northwestern Engineering-led team has developed a highly porous smart sponge that selectively soaks up oil in water. With an ability to absorb more than 30 times its weight in oil, the sponge could be used to clean up oil spills inexpensively and efficiently without harming marine life. —Vikas Nandwana.

UCSD/Sapphire team shows marine algae can be engineered to perform as well as fresh water algae to produce enzymes and biofuels; removing the constraint of fresh water

Green Car Congress

have demonstrated for the first time that genetically engineered marine algae can be just as capable as fresh water algae in producing industrially relevant products such as enzymes or biofuels. What our research shows is that we can achieve in marine species exactly what we’ve already done in fresh water species.

USC study shows promising potential for giant-kelp-based biofuel with depth-cycling approach

Green Car Congress

physically moving the macroalgae between deep nutrient-rich water at night and shallow depths within the photic zone during the day to optimize growth. 13 C values suggesting that the depth-cycled kelp were not nitrogen-deficient and assimilated nutrients from deep water. The researchers used a depth-cycling approach—i.e.,

MBL begins first test of tropical seaweed farming for biofuels production

Green Car Congress

A team of researchers led by Loretta Roberson, associate scientist at the Marine Biological Laboratory, Woods Hole, has installed the first seaweed farm in Puerto Rico and US tropical waters. Facilitating research of this nature will be key for the development of sustainable aquaculture in this area. Earlier post.).

Chalmers study finds ship exhaust gas scrubbers responsible for up to 9% of certain hazardous emissions into Baltic Sea

Green Car Congress

New research from Chalmers University of Technology, Sweden, finds that the discharge water from ships’ exhaust gas treatment systems—i.e., For many years, we’ve flagged the fact that scrubbers account for disproportionately large emissions of hazardous and acidifying substances into the marine environment.

Rolls-Royce and Robert Allan present world’s first LNG-powered shallow-water push boat

Green Car Congress

Rolls-Royce and Canadian vessel designers Robert Allan have developed the world’s first shallow-water push boat powered by LNG natural gas engines. LNG (liquefied natural gas) is gaining traction in maritime circles, enabling operators to reduce emissions that are harmful to the environment and to the climate.
