Measurement and data analysis techniques developed at the Department of Energy’s Oak Ridge National Laboratory could provide new insight into performance-robbing flaws in crystalline structures, ultimately improving the performance of solar cells.
As part of its Game Changing Development (GCD) program, NASA has chosen four proposals to build next-generation solar array technologies for deep space missions. The aim of the program is to develop solar arrays that will help spacecraft to explore space destinations that lie outside of the low-Earth orbit.
Photocatalytic hydrogen generation via water splitting has become a hot spot in the field of energy and materials. The goal of this technique is to construct cheap and efficient photocatalytic water splitting systems at an industrial scale, which first need us to search and develop efficient photocatalysts and suitable reductive/oxidative cocatalysts.
Drones are used for various applications such as aero picturing, disaster recovery, and delivering. Despite attracting attention as a new growth area, the biggest problem of drones is its small battery capacity and limited flight time of less than an hour. A fuel cell developed by Prof. Gyeong Man Choi (Dept. of Materials Science and Engineering) and his research team at POSTECH can solve this problem.
Two new federal government reports underscore not only the continued rapid growth of renewable energy sources (i.e., biomass, geothermal, hydropower, solar, wind) in the electric power sector but also the ongoing failure of government forecasts to accurately anticipate and predict that growth.
Fossil fuels propelled the Industrial Revolution and subsequent technological advances. However, our future cannot be based on them, if only because they are a finite resource; and we are very close to exhausting them.
Vehicle fuels obtained from plant wastes are generally climate friendly and sustainable. However obtaining energy stored in stems, twigs, and bark is a challenging process as it is locked up in the cellulose.
If you buy a hybrid SUV rather than a conventional SUV of equal size, you naturally think you have chosen the "green" option. But that hybrid vehicle is not greener than a conventional compact car that gets poorer mileage than the hybrid.
Researchers from the Gas Engineering Department at the Petroleum University of Technology, in Ahwaz, Iran, have created a high-speed conversion method capable of turning waste cooking oil into fuel, using caustic soda and ultrasound. Biodiesel signifies a fuel that is likely to be cleaner and more sustainable than crude oil-based fuels.
An assistant research specialist at the Great Lakes Bioenergy Research Center (GLBRC) has designed a new strain of yeast that could improve the efficiency of making fuel from cellulosic biomass such as switchgrass.
