Next-generation solar cells pass strict international tests
21 May 2020 at 12:19pm
A cost-effective method to stabilise perovskite solar cells could soon see them become commercially viable.
3D-printed system speeds up solar cell testing from hours to minutes
20 May 2020 at 10:16am
Tests on new designs for next-gen solar cells can now be done in minutes instead of days thanks to a new system.
US wind plants show relatively low levels of performance decline as they age
13 May 2020 at 8:14am
Wind plants in the United States remain relatively efficient over time, with only a 13% drop in performance over 17 years, researchers report. Their study also suggests that a production tax credit provides an effective incentive to maintain the plants during the 10-year window in which they are eligible to receive it. When this window closes, wind plant performance drops.
The role of European policy for improving power plant fuel efficiency
8 May 2020 at 3:46pm
A new study investigates the impact of the European Union Emissions Trading Scheme (EU ETS), the largest international cap-and-trade system for greenhouse gas emissions in the world, on power plant fuel efficiency.
Saving energy and lives: How a solar chimney can boost fire safety
5 May 2020 at 4:22am
Built as part of the sustainable features of a new Australian building, the specially-designed solar chimney radically boosts safe evacuation time in a fire - from 2 minutes to over 14 minutes.
Solar and wind energy sites mapped globally for the first time
4 May 2020 at 12:02pm
Researchers have mapped the global locations of major renewable energy sites, providing a valuable resource to help assess their potential environmental impact.
Are salt deposits a solution for nuclear waste disposal?
29 Apr 2020 at 4:58am
Researchers testing and modeling to dispose of the current supply of waste.
Researchers make key advance toward production of important biofuel
27 Apr 2020 at 11:05am
An international research collaboration has taken an important step toward the commercially viable manufacture of biobutanol, an alcohol whose strong potential as a fuel for gasoline-powered engines could pave the path away from fossil fuels.
Environment-friendly compound shows promise for solar cell use
24 Apr 2020 at 10:26am
A team of engineers, material scientists, and physicists demonstrated how a new material -- a lead-free chalcogenide perovskite -- that hadn't previously been considered for use in solar cells could provide a safer and more effective option than others that are commonly considered.
Advancing high temperature electrolysis: Splitting water to store energy as h...
21 Apr 2020 at 10:44am
Recently, researchers developed a new electrode material for an electrochemical cell that can efficiently convert excess electricity and water into hydrogen. When demand for electricity increases, the electrochemical cell is reversible, converting hydrogen back into electricity for the grid. The hydrogen could also be used as fuel for heat, vehicles or other applications.
Why relying on new technology won't save the planet
20 Apr 2020 at 9:55am
Over-reliance on promises of new technology to solve climate change is enabling delay, say researchers. They argue instead for cultural, social and political transformation to enable widespread deployment of both behavioral and technological responses to climate change.
Physicists develop approach to increase performance of solar energy
20 Apr 2020 at 9:54am
Experimental condensed matter physicists have developed an approach to circumvent a major loss process that currently limits the efficiency of commercial solar cells.
Gas storage method could help next-generation clean energy vehicles
16 Apr 2020 at 12:17pm
A Northwestern University research team has designed and synthesized new materials with ultrahigh porosity and surface area for the storage of hydrogen and methane for fuel cell-powered vehicles. The materials, a type of a metal-organic framework (MOF), can store significantly more hydrogen and methane than conventional adsorbent materials at much safer pressures and at much lower costs. A one-gram sample of the material (with a volume of six M&Ms) has a surface area that would cover 1.3 football fields.
Six-junction solar cell sets two world records for efficiency
14 Apr 2020 at 2:32pm
Scientists have fabricated a solar cell with an efficiency of nearly 50%. The six-junction solar cell now holds the world record for the highest solar conversion efficiency at 47.1%, which was measured under concentrated illumination. A variation of the same cell also set the efficiency record under one-sun illumination at 39.2%.
Supercomputing future wind power rise
14 Apr 2020 at 6:57am
First detailed study of scenarios for how wind energy can expand to 20 percent of total US electrical supply by 2030. Results showed expansion of installed capacity makes small impact on efficiency and local climate by deploying next generation, larger wind turbines. Improved calculations of US wind resources can ensure better decision making and a better, more robust energy supply.
