Photocatalytic optical fibers convert water into hydrogen

Green Car Congress

Researchers at the University of Southampton have transformed optical fibers into photocatalytic microreactors that convert water into hydrogen fuel using solar energy. The researchers have published their proof-of-concept in ACS Photonics and will now establish wider studies that demonstrate the scalability of the platform.

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

Green Car Congress

Scientists at the USC Wrigley Institute for Environmental Studies on Santa Catalina Island, working with private industry, report that a new aquaculture technique on the California coast significantly increases kelp growth, yielding four times more biomass than natural processes. The researchers used a depth-cycling approach—i.e.,

A New Energy-Efficient Hydrogel Pulls Water From Air

Cars That Think

Using a new kind of hydrogel material, researchers at the University of Texas at Austin have pulled water out of thin air at temperatures low enough to be achieved with sunlight. Atmospheric water harvesting draws water from humidity in the air. The material is a hydrogel, a polymer network that naturally retains a lot of water.

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. It is an independent evaluation of the design concept within a given framework and states that the design is fundamentally feasible and there are no fundamental implementation concerns.

PNNL’s hydrothermal liquefaction shows promise for turning toxic algal blooms into biocrude

Green Car Congress

One year into the ERDC project, the team demonstrated a three-step approach that “cleans” the water, removes the algae and entrained nutrients such as nitrogen and phosphorus from the water, and transforms the algae into a potential energy source. Algae biorefinery concept through HTL. It was a great proof of concept.
