Johnny heath corpus christi Affordable Hydrogen Fuel Cells News Promising new prototype of battery

An alternative technology to Li-ion has been designed for application in specific sectors. The researchers have developed the first battery using sodium ions in the usual "18650" format, an industry standard. The main advantage of the prototype is that it relies on sodium, an element far more abundant and less costly than lithium. The batteries have displayed performance levels comparable to their lithium counterparts, and this new technology is already attracting industrial interest. It could be used to store renewable energies in the future, say researchers.

Johnny heath corpus christi Affordable Hydrogen Fuel Cells News Graphene’s stabling influence

Supercapacitors can be charged and discharged tens of thousands of times, but their relatively low energy density compared to conventional batteries limits their application for energy storage. Now, researchers in Singapore have developed an 'asymmetric' supercapacitor based on metal nitrides and graphene that could be a viable energy storage solution.

Johnny heath corpus christi Affordable Hydrogen Fuel Cells News More efficient biosensors for monitoring glucose levels in the field

The need for low-cost portable devices to measure substances of medical or biological interest (blood sugar levels, for instance) is growing, primarily within the health sector, though also areas such as food quality and environmental monitoring. Sending samples off to a clinical chemistry laboratory for analysis is expensive, and it takes a long time for results to reach the patient. Devices for use in the field, at point-of-care or in non-hospital settings would constitute an efficient alternative were they able to give accurate readings under non-laboratory conditions.

Johnny heath corpus christi Affordable Hydrogen Fuel Cells News Super environmentally friendly: the 'fool’s gold battery'

High-performance lithium ion batteries face a major problem: Lithium will eventually start to run out as batteries are deployed in electric cars and stationary storage units. Researchers have now discovered an alternative: the “fool’s gold battery”. It consists of iron, sulfur, sodium and magnesium – all elements that are in plentiful supply. This means that giant storage batteries could be built on the cheap and used stationary in buildings or next to power plants, for instance.

Converting solar or wind into carbon-based 'fossil' fuels might seem anything but green, but when you start with carbon dioxide -- which can be dragged out of the air -- it's as green as it gets. The technology that makes it economically feasible isn't available yet, but a recently published paper presents nice step forward in the effort to not just sequester carbon dioxide, but turn it into a useful fuel that is part of a carbon-neutral future.
