Renewables are a better investment than carbon capture for tackling climate c...
8 Apr 2019 at 8:40am
Solar panels and wind turbines coupled with energy storage offer a better hope for tackling climate change than trying to capture carbon from fossil fuel power stations, according to new research. New research shows that resources that would be spent on developing and installing carbon capture technologies would be better invested in creating more solar panels and wind turbines and focusing on developing energy storage options to support these instead.
The complicated future of offshore wind power in the US
2 Apr 2019 at 1:45pm
In recent years the US Department of Energy laid out an ambitious plan to grow the US offshore wind sector. Researchers make the case that it might not be as easy as it seems, citing specifically the challenge of supplying rare-earth metals needed to build these offshore wind turbines.
How to ice-proof the next generation of aircraft
1 Apr 2019 at 10:30am
To prevent ice formation on aircraft during flight, current systems utilize the heat generated by burning fuel, but these high-temperature, fuel-dependent systems cannot be used on the proposed all-electric, temperature-sensitive materials of next-generation aircraft. As some scientists search for new anti-icing methods, some have taken a different approach. They've published evidence showing that equipment important in controlling landing and takeoff can double-up as icing control. It depends on plasma actuators.
Good news! Europe's electric grid will still work even as the world crumbles
6 Mar 2019 at 8:07am
Temperatures may climb and seas may rise, but the lights (and, undoubtedly, the air conditioning) will still be on in nations with high capacities for wind and solar energy. New research suggests that these electricity systems should work almost equally well in both historical and future European climates despite changing weather patterns.
How power-to-gas technology can be green and profitable
26 Feb 2019 at 8:23am
Hydrogen production based on wind power can already be commercially viable today. Until now, it was generally assumed that this environmentally friendly power-to-gas technology could not be implemented profitably. Economists have now described, based on the market situations in Germany and Texas, how flexible production facilities could make this technology a key component in the transition of the energy system.
Renewable energy generation with kites and drones
19 Feb 2019 at 10:27am
A group of researchers has recently developed a new software aimed at the analysis of energy generation systems based on kites and drones. They used the software to study the behavior of these systems while transforming the kinetic energy of the wind into useful electrical energy.
Spacecraft measurements reveal mechanism of solar wind heating
14 Feb 2019 at 5:46am
A new study describes the first direct measurement of how energy is transferred from the chaotic electromagnetic fields in space to the particles that make up the solar wind, leading to the heating of interplanetary space.
Flags that generate energy from wind and sun
11 Feb 2019 at 8:42am
Scientists have created flags that can generate electrical energy using wind and solar power.
North Sea rocks could act as large-scale renewable energy stores
21 Jan 2019 at 8:53am
Rocks in the seabed off the UK coast could provide long-term storage locations for renewable energy production, new research suggests.
Engineers, zoologists reveal how gulls 'wing morph' for stable soaring
2 Jan 2019 at 8:28am
Aviation experts and zoologists have provided new insights into how gulls configure their wing shape -- known as wing morphing -- to stabilize their flight. The findings could be used to design more efficient flying vehicles, including soaring drones for farming or environmental monitoring.
Understanding dynamic stall at high speeds
18 Dec 2018 at 9:31am
Although many fixed-wing aircraft can withstand similar rapid pitch-up maneuvers, a vehicle subject to this dynamic stall process is not reliably controllable. Motivated by the lack of detailed understanding, researchers took a deep dive into the physics of dynamic stall so that it can be used beneficially and reliably by aircraft.
Upwind wind plants can reduce flow to downwind neighbors
18 Dec 2018 at 8:51am
New research highlights a previously unexplored consequence of the global proliferation of wind energy facilities: a wake effect from upwind facilities that can reduce the energy production of their downwind neighbors.
How plants can generate electricity to power LED light bulbs
12 Dec 2018 at 6:33am
Researchers have discovered that living plants are literally 'green' power source: they can generate, by a single leaf, more than 150 Volts, enough to simultaneously power 100 LED light bulbs. Researchers also showed that an 'hybrid tree' made of natural and artificial leaves can act as an innovative 'green' electrical generator converting wind into electricity.
Fine-tuning renewables could help Texas balance energy resources
5 Dec 2018 at 11:27am
A new study analyzes Texas' mix of wind and solar energy resources, and how to achieve better balance between them going forward.
New catalyst produces cheap hydrogen fuel
29 Nov 2018 at 7:00am
Chemistry researchers have discovered cheaper and more efficient materials for producing hydrogen for the storage of renewable energy that could replace current water-splitting catalysts.
