The recent dramatic decline in battery prices has created a new possibility for electrification of freight trains. Researchers from Lawrence Berkeley National Laboratory, collaborating with UCLA and UC Berkeley researchers, make the case that the U.S. can retrofit diesel-electric trains with batteries in a way that is cost-competitive with diesel. Doing so would avoid up to 1,000 premature deaths and save the U.S. freight rail sector $94 billion over 20 years from reduced air pollution and carbon dioxide emissions.
Could a tank of ice or hot water be a battery? Yes! If a battery is a device for storing energy, then storing hot or cold water to power a building’s heating or air-conditioning system is a different type of energy storage. Known as thermal energy storage, the technology has been around for a long time but has often been overlooked. Now scientists at Lawrence Berkeley National Laboratory are making a concerted push to take thermal energy storage to the next level.
Researchers at Berkeley Lab and UC Berkeley have demonstrated how coating copper catalysts with thin films can improve a standard technique for converting carbon dioxide emissions into useful chemicals and liquid fuels.
Berkeley Lab has been awarded more than $13 million for five research projects that will accelerate the development of advanced lithium batteries and smart, connected vehicles, making it easier to switch to electric vehicles.
Building operations account for a whopping 35% of U.S. carbon dioxide emissions. A free online tool developed by Berkeley Lab with support from the U.S. Department of Energy’s (DOE) Building Technologies Office (BTO) — the Building Efficiency Targeting Tool for Energy Retrofits (BETTER) — is helping to bring that number down by virtually evaluating buildings for immediate no- and low-cost energy efficiency upgrades.
A Q&A with Berkeley Lab scientists on how hydrogen can help achieve net-zero emissions. Adam Weber is Berkeley Lab’s Hydrogen and Fuel Cell Technologies Program Manager and leads Berkeley Lab’s Energy Conversion Group (ECG), and Ahmet Kusoglu is a staff scientist in the ECG, a multidisciplinary team of electrochemists, chemical engineers, mechanical engineers, theorists, and material scientists with active collaborations across industry, academia, and national laboratories.
Having good room ventilation to dilute and disperse indoor air pollutants has long been recognized, and with the COVID-19 pandemic its importance has become all the more heightened. But new experiments by Berkeley Lab indoor air researchers show that certain circumstances will result in poor mixing of room air, meaning airborne contaminants may not be effectively dispersed and removed by building level ventilation.
Wind energy continues to see strong growth, solid performance, and low prices in the U.S., according to a report released by the U.S. Department of Energy and prepared by Lawrence Berkeley National Laboratory. With levelized costs of just over $30 per megawatt-hour (MWh) for newly built projects, the cost of wind is well below its grid-system, health, and climate benefits.
Berkeley Lab and Stanford researchers collaborate to find promising solution for converting waste heat to electricity.
