By Kristi L Bumpus Ten years ago, the Department of Energy put out a call for innovators to change the world of nuclear energy. What DOE hoped to accomplish with the then-new Energy Innovation Hubs concept was “translational research” — research and development on an accelerated timeline that could solve the problems facing the nuclear…

By Jennifer J Burke The Department of Energy’s Oak Ridge National Laboratory researchers have designed and additively manufactured a first-of-its-kind aluminum device that enhances the capture of carbon dioxide emitted from fossil fuel plants and other industrial processes. Solutions for reducing global emissions of heat-trapping greenhouse gases such as CO2 address the continued use of…

By Rachel Berkowitz Capacitors that rapidly store and release electric energy are key components in modern electronics and power systems. However, the most commonly used ones have low energy densities compared to other storage systems like batteries or fuel cells, which in turn cannot discharge and recharge rapidly without sustaining damage. Now, as reported in…

UC Riverside engineers have developed a way to recycle PET plastic waste, such as soda or water bottles, into a nanomaterial useful for energy storage.

Oak Ridge National Laboratory researchers have developed a machine learning model that could help predict the impact pandemics such as COVID-19 have on fuel demand in the United States. Called the Pandemic Oil Demand Analysis, or PODA, this model compared mobility patterns before and during the COVID-19 pandemic, analyzing historical weekly motor travel trends and…

by Theresa Duque (Adapted from news release by Robert Perkins, Caltech) The quest for renewable fuels harvested from the sun continues, as the U.S. Department of Energy (DOE) has announced two new major awards focused on advancing artificial photosynthesis technologies for the production of fuels from sunlight. As part of this effort, DOE has awarded…

A research proposal submitted by the Center for Functional Nanomaterials (CFN) and Nuclear Science and Technology (NST) Department at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory, with the startup Forge Nano as a partner, has been selected as a 2020 Technology Commercialization Fund (TCF) project. Of the 82 technologies selected from among more…

Southwest Research Institute is developing machine learning algorithms to measure fugitive methane emissions through a project funded by the U.S. Department of Energy through the Office of Fossil Energy and managed at the National Energy Technology Laboratory (NETL). The project leverages an SwRI technology previously funded by DOE, Smart Methane Leak Detection, or SLED/M —…

By Julie Chao   Farmers have enough worries – between bad weather, rising costs, and shifting market demands – without having to stress about the carbon footprint of their operations. But now a new set of projects by scientists at Lawrence Berkeley National Laboratory (Berkeley Lab) could make agriculture both more sustainable and more profitable.…

By Stephanie G Seay Researchers at the Department of Energy’s Oak Ridge National Laboratory (ORNL) in late February demonstrated a 20-kw bi-directional wireless charging system installed on a UPS medium-duty, plug-in hybrid electric delivery truck. The project is the first of its kind to achieve power transfer at this rate across an 11-in. air gap,…

HUBER+SUHNER, a global supplier of electrical and optical connectivity solutions, has launched the RADOX HPC500; a new addition to the RADOX high-power charging portfolio. It is the world’s first cooled charging-cable system that allows continuous charging at 500 Amperes even in high-temperature environments. The HPC500 cable and connecter builds on the proven performance and design…

By Grace Niewijk As global temperatures and energy demand rise simultaneously, the search for sustainable fuel sources is more urgent than ever. But how can renewable energy possibly scale up to replace the vast quantities of oil and gas we consume? Plant power is a significant piece of the answer, says Purdue scientist Maureen McCann.…

New battery technology involving microwaves may provide an avenue for renewable energy conversion and storage. Purdue University researchers created a technique to turn waste polyethylene terephthalate, one of the most recyclable polymers, into components of batteries. “We use an ultrafast microwave irradiation process to turn PET, or polyethylene terephthalate, flakes into disodium terephthalate, and use…

Using electronic devices for too long can cause them to overheat, which might slow them down, damage their components or even make them explode or catch fire. Now, researchers reporting in ACS’ Nano Letters have developed a hydrogel that can both cool down electronics, such as cell phone batteries, and convert their waste heat into…

By Chris Adam An innovation using material derived from the shells of crabs and other sea creatures may soon provide a new option for powering medical sensors, phone screens and other devices.

Since their invention in the 1930s, electron microscopes have helped scientists peer into the atomic structure of ordinary materials like steel, and even exotic graphene. But despite these advances, such imaging techniques cannot precisely map out the 3D atomic structure of materials in a liquid solution, such as a catalyst in a hydrogen fuel cell,…

For years physicists have been trying to decipher the electronic details of high-temperature superconductors. These materials could revolutionize energy transmission and electronics because of their ability to carry electric current with no energy loss when cooled below a certain temperature. Details of “high-Tc” superconductors’ microscopic electronic structure could reveal how different phases (states of matter)…
