Battery vehicle now viable for very long distances
The Tesla 3 gets nearly double the range of the Nissan Leaf by using nearly double the amount of battery but engineers are using a multitude of work rounds to do better: aerodynamics, lightweighting even including structural electronics where dumb structure is replaced by supercapacitors or solid state batteries. Add more efficient motors and powertrain. Fuel cell hybrids retain the cachet of most expensive solution with a long on-road charging t...
The latest advances on light harvesting potentials
Researchers for the first time have found a quantum-confined bandgap narrowing mechanism where UV absorption of the grapheme quantum dots and TiO2 nanoparticles can easily be extended into the visible light range. Such a mechanism may allow the design of a new class of composite materials for light harvesting and optoelectronics.
Measuring greenhouse gases from space
Space agencies examine the extent of greenhouse gases in the air via prisms and gratings in satellites. The latest technology now makes it possible to connect both components with each other so that they are suitable for space thus achieving a new level of quality for spectral resolution. In addition to industrial CO2 emissions, agriculture also contributes significantly to climate change: above all methane (CH4) and nitrous oxide (N2O), which ar...
Improving grid-scale batteries
A Stanford University research lab has developed technologies to tackle two of the world’s biggest energy challenges – clean fuel for transportation and grid-scale energy storage. The researchers described their findings in two studies published this month in the journals Science Advances and Nature Communications.
In-wheel motors power innovative Rasa hydrogen car
The Rasa hydrogen fuel cell car developed by Riversimple has been attracting a lot of attention with its innovative design and impressive performance. A key feature is its four in-wheel electric motors which directly drive the vehicle's wheels. The thin, powerful pancake motors were developed for the UK company by Printed Motor Works, and had to meet a number of demanding requirements.
Storage systems for green energy from Saxony-Anhalt
The picturesque Saxony Anhalt, Germany's 8th largest state,is home to some 23,000 photovoltaic systems. Around 2,700 wind turbines operate at 97 wind power plants between the Altmark and Harz regions. Therenewable energy sectoris booming here - and storage solutions for the green electricity being generated are urgently required.
Hydrogen dual-fuel bin lorries hit the roads in the UK
A company championing the use of ultra-low emission hydrogen fuelled vehicles, has delivered the world’s first hydrogen dual-fuel bin lorries to Fife Council in Scotland. The lorries are converted to run on dual hydrogen/diesel fuels, and will deliver reduced carbon emissions as well as improving air quality for the local community. The new bin lorries are planned for use in densely populated urban areas, where improving air quality is a hu...
Solar power home storage systems will be put to test
Home storage systems for electricity produced by photovoltaics facilities are gaining attractiveness, as their costs are declining. However, standardised, verifiable criteria for the end client to assess their performance are still lacking. Now, scientists have launched the largest German study so far to analyse commercial systems with respect to safety, quality, and grid suitability and to derive recommendations for manufacturers, standardisatio...
Eggshells could be turned into battery electrodes
Americans consume 76 billion eggs per year, and while some of the eggshell waste is used for fertilizer or dietary supplements, the majority of these eggshells are thrown away. In a study, researchers at Wayne State University in Detroit have developed a method to recycle eggshells, using them as "chemical reactors" to synthesise sulfur-containing nanorods that can be used as battery electrodes.
Converting solar energy into chemical energy
A project called LightChEC, running at the University ofZurich since the beginning of 2013,focuses on "turning solar energy into chemical energy".The researchers involved are aiming to refine artificial photosynthesis to make it suitable as a means for supplying energy to industry and society. Three Empa scientists, Andreas Borgschulte, Karl-Heinz Ernst and Andreas Züttel, are carrying out research as part of LightChEC. Ernst and Züttel...
