Kentucky to get a new closed loop water battery facility

 



An American company Rye Development, are intending to build a long duration electrical storage project using a closed loop pumped hydropower system. This is in Kentucky which is not known for its renewable energy generation. It has a low amount of wind and solar power. One of the big problems with renewables is energy storage and this company is proposing a water battery whereby large volumes of water can easily be stored in a high-level reservoir and then released into a low-level reservoir. When electricity is made and not used then the extra electricity can be used to pump the water from the lower reservoir into the higher reservoir typically at night wind the wind is blowing and the demand is low. The company also plan to install significantly more solar and wind farms. This is probably a good sign since Kentucky is one of those great call orientated American states.

New photocatalyst made from an aerogel for more efficient hydrogen production

Image
  Researchers at ETH Zurich have developed a new photocatalyst made from an aerogel that could enable more efficient hydrogen production. One use for aerogels based on nanoparticles is as photocatalysts. These are employed whenever a chemical reaction needs to be enabled or accelerated with the aid of sunlight – one example being the production of hydrogen. The material of choice for photocatalysts is titanium dioxide (TiO 2 ), a semiconductor. But TiO 2  has a major disadvantage: it can absorb only the UV portion of sunlight – just about 5 percent of the spectrum. If photocatalysis is to be efficient and industrially useful, the catalyst must be able to utilise a broader range of wavelengths. Junggou Kwon has been looking for a new way to optimise an aerogel made of TiO 2  nanoparticles. And she had a brilliant idea: if the TiO 2  nanoparticle aerogel is “doped” (to use the technical term) with nitrogen, such that individual oxygen atoms in the material are repla...

Spider webs near roads capture all types of Micro plastics and could be used for monitoring pollution

Image
Researchers at the University of Oldenburg have been examining spider webs webs for the smallest plastic particles – on inner-city streets with varying levels of traffic. They found mainly the plastic PET, presumably from textiles, as well as particles from the abrasion of car tyres and polyvinyl chloride (PVC). The amounts of plastic particles found depended on the location. Spider webs, the team concludes, are a simple and inexpensive means of monitoring air pollution by microplastics in the city and identifying particularly polluted areas.  The samples, collected in a mid-sized German city, were processed with  Fentons  reagent and measured using pyrolysis-gas chromatography–mass spectrometry for specific, polymer related indicator compounds. All samples contained    microplastics (MP) including tyre wear particles (TWP) contamination in air samples.  All the spider webs were contaminated with microplastics. In some cases, the plastic content even accoun...

​ New artificial leaf can capture 100 times more carbon in normal conditions

Image
  Engineers at the University of Illinois have managed to construct a cost-effective artificial leaf that can capture carbon dioxide 100 times better than any current system works in normal air which is containing very dilute sources of carbon dioxide. This artificial leaf is a modified version of existing systems with a built-in water gradient creating a dry on a wet side across a charged membrane. On the dry side and organic solvent attaches to the carbon dioxide producing a concentrated by carbonate solution. As the bicarbonate solution increases these are pulled across the membrane towards a positively charged electrode in a water-based solution. The liquid solution dissolves the HCO3 back into carbon dioxide so that it can be released and harnessed for fuel uses. The current system is small enough to fit in a backpack and uses less than the electricity used by 1 W LED lightbulb. The system is stackable so that modules can be added or subtracted and could be affordable are used...
