Solar energy researchers are shining their scientific spotlight on materials with a crystal structure discovered nearly two centuries ago.
New solar forecasting model performs best
29 Jun 2020 at 9:02am
A new mathematical model for predicting variations in solar irradiance has been developed. It may help to promote more efficient use of electricity from solar energy. In tests of various data models, the model proved capable of making highly reliable forecasts, and emerged as the best for this purpose in some respects.
Self-powered alarm fights forest fires, monitors environment
24 Jun 2020 at 12:15pm
Scientists designed and fabricated a remote forest fire detection and alarm system powered by nothing but the movement of the trees in the wind.
How a historic drought led to higher power costs and emissions
20 Jun 2020 at 11:19am
Researchers studied the impact of a historic drought in California on economic and environmental impacts for electric power systems.
Simulating wind farm development
19 Jun 2020 at 11:33am
Engineers have devised a model to describe how, in the process of establishing wind farms, interactions between developers and landowners affect energy production costs.
New system uses wind turbines to defend the US national grid from power cuts
19 Jun 2020 at 8:57am
A 'smart' system that controls the storage and release of energy from wind turbines will reduce the risk of power cuts and support the increase of wind energy use world-wide, say researchers.
The exhaust gas from a power plant can be recovered and used as a raw reactio...
19 Jun 2020 at 6:42am
A research group developed a new technology that can drastically conserve the energy used to capture CO2 from gases exhausted from a concentrated source such as thermal power plants. With this technology, namely H2 stripping regeneration technology, combustion exhaust gas can be replaced by CO2/H2 gas at lower temperatures than those used in conventional technology.
Integrating nanomaterial with light-absorbing molecule powers hydrogen produc...
8 Jun 2020 at 10:25am
Scientists have developed a hybrid material constructed from a metal oxide nanosheet and a light-absorbing molecule for splitting water molecules (H2O) to obtain dihydrogen (H2) under sunlight. Since H2 can be used as carbon-free fuel, this study provides relevant insight towards clean energy generation.
Researchers advance fuel cell technology
8 Jun 2020 at 6:29am
Researchers have made a key advance in solid oxide fuel cells (SOFCs) that could make the highly energy-efficient and low-polluting technology a more viable alternative to gasoline combustion engines for powering cars.
Double-sided solar panels that follow the sun prove most cost effective
3 Jun 2020 at 10:25am
Solar power systems with double-sided (bifacial) solar panels -- which collect sunlight from two sides instead of one -- and single-axis tracking technology that tilts the panels so they can follow the sun are the most cost effective to date, researchers report. They determined that this combination of technologies produces almost 35% more energy, on average, than immobile single-panel photovoltaic systems, while reducing the cost of electricity by an average of 16%.
Solar hydrogen production: Splitting water with UV is now at almost 100% quan...
3 Jun 2020 at 7:45am
Scientists have successfully split water into hydrogen and oxygen using light and meticulously designed catalysts, and they did so at the maximum efficiency meaning there was almost no loss and undesired side reactions. This latest breakthrough in solar hydrogen production makes the likelihood of scalable, economically viable hydrogen production more than likely, paving the way for humanity to make the switch to clean energy.
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.
