Fuel from the air technology provides a path to new business for OPEC countries
24 May 2017 at 5:46am
Pioneering technology makes OPEC countries prime regions to produce synthetic fuels. This could be a key asset in phasing out fossil fuels after the Paris Agreement, while also keeping some of the existing oil industry value chain intact.
Special X-ray technique allows scientists to see 3-D deformations
23 May 2017 at 11:41am
Researchers have used an X-ray scattering technique called Bragg coherent diffraction imaging to reconstruct in 3-D the size and shape of grain defects. These defects create imperfections in the lattice of atoms inside a grain that can give rise to interesting material properties and effects.
Solar cells more efficient thanks to new material standing on edge
23 May 2017 at 5:42am
Researchers have designed a new structural organization using the promising solar cell material perovskite. The study shows that solar cells increase in efficiency thanks to the material?s ability to self-organize by standing on edge.
Energy transition: Smart, interconnected, sustainable
18 May 2017 at 5:53am
Many elements are required for making the energy system more sustainable. Among them are smart solar storage systems, smartly interconnected energy grids, and electricity-based synthetic fuels (e-fuels).
Autonomous 'soaring with solar' concept
17 May 2017 at 7:11am
Scientists are building on the proven concept of autonomous cooperative soaring of unmanned aerial vehicles (UAVs), which enables long endurance flights of unmanned sailplanes that use the power of the Sun.
New, more efficient catalyst for water splitting
15 May 2017 at 12:07pm
Physicists have discovered a catalyst that can split water into hydrogen and oxygen, composed of easily available, low-cost materials and operating far more efficiently than previous catalysts. That would solve one of the primary hurdles remaining in using water to produce hydrogen, one of the most promising sources of clean energy.
Key differences in solar wind models
15 May 2017 at 9:59am
The challenge of predicting space weather, which can cause issues with telecommunications and other satellite operations on Earth, requires a detailed understanding of the solar wind (a stream of charged particles released from the sun) and sophisticated computer simulations. New research has found that when choosing the right model to describe the solar wind, using the one that takes longer to calculate does not make it the most accurate.
Photovoltaics and batteries: An expensive combination
15 May 2017 at 6:26am
Solar power can cover up to 40% of the electricity needs of a typical household. Going beyond that level becomes really expensive: using batteries coupled with solar panels would be twice as expensive as using the power grid.
Data science used to better predict effect of weather and other conditions
12 May 2017 at 4:57pm
Data science has been used by researchers to determine and predict the effects of exposure to weather and other conditions on materials in solar panels. Using data science to predict the deterioration of such materials could lead to finding new ways to extend their lifetime, the researchers say.
Next-gen solar cells could be improved by atomic-scale redesign
12 May 2017 at 6:39am
Researchers have uncovered the exact mechanism that causes new solar cells to break down in air, paving the way for a solution.
Power plants could cut a third of their emissions by using solar energy
9 May 2017 at 5:38am
The COMBO-CFB project has developed a new innovative concept to increase solar energy production in the energy system. According to this research, the concept can reduce fuel consumption and emissions stressing the climate by more than 33 per cent. The concept is based on the combination of concentrated solar power (CSP) technology and a traditional power plant process into a hybrid plant which produces electricity on the basis of consumption.
Installing solar to combat national security risks in the power grid
8 May 2017 at 8:24am
Power grid vulnerabilities are one of the most prevalent national security threats. The technical community calls for building up grid resiliency using distributed energy and microgrids for stabilization as multiple sources increases the difficulty of triggering cascading blackouts, and following an attack or natural disaster, microgrids can provide localized energy security. An interdisciplinary team calculated what it takes to make military bases more secure.
New technology generates power from polluted air
8 May 2017 at 5:32am
Researchers have succeeded in developing a process that purifies air and, at the same time, generates power. The device must only be exposed to light in order to function.
Photoluminescent display absorbs, converts light into energy
2 May 2017 at 6:50am
A new study demonstrates how to convert a luminescent solar concentrator into an energy-harvesting laser phosphor display by projecting intensity modulated light.
Solar cells with nanostripes
2 May 2017 at 5:46am
Solar cells based on perovskites reach high efficiencies: they convert more than 20 percent of the incident light directly into usable power. On their search for underlying physical mechanisms, researchers have now detected strips of nanostructures with alternating directions of polarization in the perovskite layers. These structures might serve as transport paths for charge carriers.
