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.

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.

Fusion Fuel and Ballard Power commission H2Évora, Portugal’s first solar-to-green hydrogen facility

Green Car Congress

The demonstration project, comprising 15 HEVO-Solar units and associated balance-of-plant equipment, will produce 15 tons of green hydrogen per year and avoid the emission of 135 tons of CO 2 annually. HEVOs are affixed to the back of high-efficiency concentrated photovoltaic (CPV) panels to make a HEVO-Solar generator.

Japan team evaluates battery-assisted low-cost hydrogen production from solar energy

Green Car Congress

Researchers from Japan’s NIMS (National Institute for Materials Science), the University of Tokyo and Hiroshima University have jointly conducted a techno-economic analysis for hydrogen production from photovoltaic power generation (PV) utilizing a battery-assisted electrolyzer. This approximately converts to US$1.92 to US$3.00/kg

KU Leuven team creates solar panel that produces hydrogen from moisture in air

Green Car Congress

Bioscience engineers at KU Leuven have created a solar panel that produces hydrogen gas from moisture in the air. Twenty of these solar panels could provide electricity and heat for one family for an entire winter. A traditional solar panel converts between 18 to 20% of the solar energy into electricity.

All-in-one solar-powered tower makes carbon-neutral kerosene in the field at pilot-scale

Green Car Congress

We are the first to demonstrate the entire thermochemical process chain from water and CO 2 to kerosene in a fully-integrated solar tower system. Previous attempts to produce aviation fuels through the use of solar energy have mostly been performed in the laboratory. B) Photograph of the solar tower fuel plant during operation.
