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 microstructured optical fiber canes (MOFCs) with photocatalyst generate hydrogen that could power a wide range of sustainable applications. Potter, Daniel J.

New photocatalytic system converts carbon dioxide to valuable fuel more efficiently than natural photosynthesis

Green Car Congress

The new system mimics a natural chloroplast to convert carbon dioxide in water into methane, very efficiently using light. However, it is difficult to convert carbon dioxide in water because many photosensitizers or catalysts degrade in water. A paper on this team’s latest work was published in Nature Catalysis.

Qatar researchers review hydrogen production from on-board ammonia decomposition

Green Car Congress

A team from Hamad Bin Khalifa University in Qatar has comprehensively reviewed various ammonia decomposition techniques to produce clean hydrogen by recovering the boil-off ammonia while integrating solar energy infrastructures onboard a ship for electricity and heat requirements. The review paper is published in the journal Fuel.

Researchers use chemical looping process to produce hydrogen from hydrogen sulfide gas

Green Car Congress

Researchers at The Ohio State University have used a chemical looping process to produce hydrogen from hydrogen sulfide gas—commonly called “sewer gas”. Hydrogen sulfide is emitted from manure piles and sewer pipes and is a key byproduct of industrial activities including refining oil and gas, producing paper and mining.

CNRS researchers use boron radicals to convert nitrogen to ammonia in solution; mild ammonia synthesis

Green Car Congress

Ammonia is obtained industrially using the Haber–Bosch process, which requires a lot of energy and hydrogen gas. The boron compounds can efficiently target atmospheric nitrogen and convert it to ammonium chloride after the addition of an acid. Resources. Bennaamane et al. Haber-Bosch production of ammonia generates around 1.6%
