Researchers have developed a method for examining the inner workings of battery-like devices called supercapacitors, which can be charged up extremely quickly and can deliver high electrical power. Their technique, based on magnetic resonance imaging (MRI), establishes a means for monitoring and potentially enhancing the performance of such devices.
The EU project CITyFiED aims to carry out an extensive demonstration of its low energy consumption concept, among other things, through in selected districts in the cities of Laguna de Duero, in Spain, Lund in Sweden and Soma in Turkey.
Scientists have synthesized a catalyst that improves their system for converting waste carbon dioxide into syngas, a precursor of gasoline and other energy-rich products, bringing the process closer to commercial viability.
Physicists have identified the 'quantum glue' that underlies a promising type of superconductivity - a crucial step towards the creation of energy superhighways that conduct electricity without current loss.
Whilst hydrogen cars look set to be the next big thing in an increasingly carbon footprint-aware society, sustainable methods to produce hydrogen are still in their early stages. The HYTIME project is working on a novel production process that will see green hydrogen being produced from grass, straw and food industry residues.
The method for measuring infrared emissivity developed by researchers in Spain is a direct method for measuring the emissivity of opaque bodies, and consists of comparing what is emitted by the body in question with what is emitted by a black body.
Climate change mitigation strategies such as the German Energiewende require linking vast numbers of new power generation facilities to the grid. As the input from many renewable sources is rather volatile, depending on how much the wind blows or the sun shines, there's a higher risk of local power instabilities and eventually blackouts. Scientists now employed a novel concept from nonlinear systems analysis called basin stability to tackle this challenge.
Spinach gave Popeye super strength, but it also holds the promise of a different power for a group of scientists: the ability to convert sunlight into a clean, efficient alternative fuel. Physicists are using spinach to study the proteins involved in photosynthesis, the process by which plants convert the sun's energy into carbohydrates used to power cellular processes. Artificial photosynthesis could allow for the conversion of solar energy into renewable, environmentally friendly hydrogen-based fuels.
No fossil fuels used for heating or hot water in an entire village - that is the ambitious goal of the Zernez Energia 2020 research project. ETH scientists have studied the feasibility of the project and are presenting the initial findings in an exhibition.
