Scientists at Oak Ridge National Laboratory and the University of Tennessee, Knoxville, have developed an algorithm to predict electric grid stability using signals from pumped storage hydropower projects.
The attractiveness of new hydropower is decreasing fast, both due to the increasing economic competitiveness of solar panels and to the increasingly uncertain effects of climate change on river flows.
Idaho National Laboratory and Pacific Northwest National Laboratory have partnered with Idaho Power to evaluate the feasibility and advantages of making hydrogen at existing hydropower plants.
Officials are continuing to sound the alarm on the severe drought conditions impacting the American Southwest and Colorado River. According to a report by The Washington Post, further receding water levels at the Glen Canyon Dam of Lake Powell could…
The U.S. Department of Energy’s Oak Ridge National Laboratory has provided hydropower operators with new data to better prepare for extreme weather events and shifts in seasonal energy demands caused by climate change.
Near-real-time fish tracking using a new acoustic receiver developed by PNNL can support enhanced fish passage through hydropower dams.
Story tips: Drought-resistant crops, hydropower, AI for atomic measurement, controlling refrigerants and recycling e-waste
ORNL Story tips: Split-second leak detection, serendipitous silicon and retrofitting untapped dams
To examine the impact of a warmer and wetter climate in High Mountain Asia, Professor Lu Xixi and Dr Dongfeng Li from the Department of Geography at the National University of Singapore (NUS) Faculty of Arts and Social Sciences led an international team of researchers to conduct a new analysis of observations of headwater rivers in the area. The study revealed that fluvial sediment loads have been increasing substantially, even much faster than river water discharge. This has important implications for water quality, hydropower development and maintenance, and for the riverine carbon cycle.
Storing greater amounts of water in Brazil’s reservoirs could increase precipitation and river flow, alleviating the water and energy supply crisis in Brazil.
Of the various methods to store renewable energy, one stands out for holding onto energy for months at a time: storing energy in the chemical bonds of molecules such as hydrogen.
IIASA researchers explored the role the Indus basin could play to support global sustainable development.
PNNL scientists developed a tiny battery and tag to track younger, smaller species, to evaluate behavior and estimate survival during downstream migration.
ORNL story tips: COVID breath-sampling, welding advances and powered by water
PNNL biologists have developed a more efficient way to estimate salmon survival through dams that uses solid science but saves over 42 percent of the cost.
A new study investigated the impacts of different levels of global warming on hydropower potential and found that this type of electricity generation benefits more from a 1.5°C than a 2°C climate scenario.
Seasonally pumped hydropower storage could provide an affordable way to store renewable energy over the long-term, filling a much needed gap to support the transition to renewable energy, according to a new study from IIASA scientists.
