Costs of solar panels have plummeted over the last several years, leading to rates of solar installations far greater than most analysts had expected. But with most of the potential areas for cost savings already pushed to the extreme, further cost reductions are becoming more challenging to find. Now, researchers at MIT and at the…

Scientists from Cornell University and the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory (BNL) have successfully demonstrated the world’s first capture and reuse of energy in a multiturn particle accelerator, where electrons are accelerated and decelerated in multiple stages and transported at different energies through a single beamline. This advance paves the way for…

Southwest Research Institute is now the home of a reciprocating compressor flow loop that is capable of recreating real-life gas pipeline pressures, temperatures and horsepower levels. The flow loop is one of only a handful of its kind available for industry research, development and testing and will play a central role in an ongoing SwRI…

Controllis, a supplier of hybrid power systems for mobile network operators (MNOs) and tower companies, has leveraged its experience to develop a carbon neutral site power system to help support a net zero emissions economy, established by the Paris Agreement. The new system, Controllis Zero will allow off-grid and poor-grid sites to produce cleaner energy…

Electricity production is one of the industries that uses the most water in the country each day. Researchers at Sandia National Laboratories are helping the largest power plant in the United States identify the most efficient and cost-effective strategies to reduce water use. They developed a first-of-its-kind comprehensive system dynamics analysis that can show power…

To better determine the potential energy cost savings among connected homes, researchers at Oak Ridge National Laboratory developed a computer simulation to more accurately compare energy use on similar weather days. “Since no two weather days are alike, we created a simulated weather identification model that keeps environmental impacts such as temperature changes and sunlight…

Evaporation ponds, which are commonly used in many industries to manage wastewater, can span acres, occupying a large footprint and often posing risks to birds and other wildlife. Yet they’re an economical way to deal with contaminated water because they take advantage of natural evaporation under sunlight to reduce large volumes of dirty water to…

Sandia National Laboratories is setting up a collaborative facility to help researchers worldwide study low-temperature plasmas, the most pervasive state of matter in the universe. The 5-year, $5.5 million project, called the Sandia Low Temperature Plasma Research Facility, is sponsored by the Department of Energy’s Office of Science. Participants will be selected biannually by Sandia…

Researchers led by the University of Manchester have designed a catalyst that converts biomass into fuel sources with remarkably high efficiency and offers new possibilities for manufacturing advanced renewable materials. Neutron scattering experiments at the Department of Energy’s Oak Ridge National Laboratory played a key role in determining the chemical and behavioral dynamics of a…

Oak Ridge National Laboratory and five leading building equipment industries will collaborate to improve the energy performance of heating, air conditioning and ventilation systems and investigate climate-friendly alternative refrigerants. Through collaborative research and development agreements, or CRADAs, scientists at the Department of Energy’s only designated national user facility for buildings research – the Building Technologies…

A Purdue University-affiliated agbioscience startup is creating technology to help meet the growing global demand for bioenergy and, in partnership with Purdue, has received new support from the U.S. government. GRYFN offers precise geomatics solutions for coaligned and repeatable multi-sensor drone data collection. The approach enables breeders to scale research operations and empowers them with…

Southwest Research Institute engineers developed a new certification cycle, the Low-Load Cycle (LLC), to gauge the performance of heavy-duty diesel engine after-treatment systems in low-load conditions. Aftertreatment systems filter exhaust emissions and reduce pollutants escaping into the environment. SwRI’s Low-Load Cycle challenges aftertreatment systems by analyzing them in unfavorable, but common, low-load conditions, such as…

Increasing production of second-generation biofuels – those made from non-food biomass such as switchgrass, biomass sorghum, and corn stover – would lessen our reliance on burning fossil fuels, which contributes to climate change. Several barriers have prevented the efficient conversion of that biomass. Lignin, a complex compound in cell walls, blocks access to plant carbohydrates…

A team of engineers, agronomists and economists at Purdue University’s Center for Sustainable Food, Energy and Water Systems (SFEWS), supported by the National Science Foundation, are developing novel photovoltaic (PV) module designs for use on agricultural land to cogenerate electricity while growing food crops. The enabling insights from their modeling results were just published in…

Today, the U.S. Department of Energy (DOE) announced $21.4 million in funding for research in Quantum Information Science (QIS) related to both particle physics and fusion energy sciences. “QIS holds great promise for tackling challenging questions in a wide range of disciplines,” said Under Secretary for Science Paul Dabbar. “This research will open up important…

One of the main challenges of second-generation biofuel production is identifying enzymes produced by microorganisms for use in a “cocktail” of enzymes to catalyze biomass hydrolysis, in which the enzymes act together to break down the carbohydrates in sugarcane trash and bagasse, for example, and convert them into simple sugars for fermentation. A group of…

Carbon-neutral fuels are crucial for making aviation and maritime transport sustainable.
