About one in four Americans today live in the vicinity of a major roadway. These Americans face widespread exposure to traffic-related air pollution, or TrAP, which is defined as a mixture of vehicle exhaust, tire and brake wear particles, and other pollutants. Underserved communities face disproportionate exposure to TrAP, making this type of pollution not only an important health concern, but an... Read more

A consortium of the nation’s best battery scientists, led by Lawrence Berkeley National Laboratory (Berkeley Lab), will accelerate the commercialization of a new family of battery cathode materials called DRX or “disordered rock salt.” DRX cathodes could provide batteries with higher energy density than conventional lithium-ion battery cathodes made of nickel and cobalt, two metals that are...

Two innovative technologies from the Energy Technologies Area (ETA) are among four at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) that have been honored with a 2023 R&D 100 Award. The award, presented by R&D Magazine and selected by an independent panel of judges, recognizes the year’s 100 most innovative and disruptive technology products from... Read more

Researchers are hard at work on ways to make buildings more energy-efficient and user-friendly as part of net zero carbon emissions energy systems. That means things like windows and walls that take advantage of nature to heat and cool, better batteries to store and deliver energy when needed, and systems that can adapt to changes from the electrical grid. What would it look like to combine all of... Read more

The U.S. electric grid faces simultaneous, evolving pressures. Demand for power from the grid is increasing as people adopt electric cars and building energy is transitioned from gas to electricity. At the same time, climate change is driving more extreme weather. Events like the 2020 heat wave that led to rolling blackouts in California are relatively infrequent, but they are happening more often... Read more

Diesel-fueled freight trucks play an outsized role in producing India’s total greenhouse gas and air pollution emissions. While the country has promoted policies to transition to electric vehicles for public transportation buses and cars, batteries that can power such large trucks have been too heavy and expensive to make their electrification possible. A new study from the Department of... Read more

Trains have been on the sidelines of electrification efforts for a long time in the U.S. because they account for only 2% of transportation sector emissions, but diesel freight trains emit 35 million metric tons of carbon dioxide annually and produce air pollution that leads to $6.5 billion in health costs, resulting in an estimated 1,000 premature deaths each year. What’s more, these deaths and... Read more

Companies like Purple Air and IQAir, with air pollution sensors that cost under $300, have brought air quality monitoring to the masses. But when Lawrence Berkeley National Laboratory (Berkeley Lab) scientist Tom Kirchstetter looked at Purple Air’s map last year during wildfire season, he noticed a big hole in Richmond, a city of 110,000 to the north of Berkeley. “You can see what appears to...

As the rate of electric vehicle (EV) adoption in the U.S. rises, the transportation sector will put additional pressure on the power grid. California expects more than 50% zero-emission vehicles (ZEVs), which includes battery EV, plug-in hybrid EV and fuel cell EV, in new vehicle sales by 2030 to achieve statewide emission and pollution reduction goals. This added pressure on the grid could be... Read more

Can scientists understand human behavior enough to figure out what drives the choices you make? In fact, it’s called “decision science,” and it’s something that Anna Spurlock, a behavioral economist with Lawrence Berkeley National Laboratory (Berkeley Lab), specializes in.Spurlock (pictured) spearheads the WholeTraveler Transportation Behavior Study, a three-year project that has attempted...

Lithium ion is probably the most advanced technology available for the packs of rechargeable batteries you’ll buy this holiday season. The batteries also power the vast majority of consumer devices, electric vehicles, and grid storage systems.Despite their ubiquity, lithium-ion batteries have disadvantages. Metals used in the batteries are becoming expensive and one crucial metal, cobalt, is... Read more

Black carbon, commonly known as soot, is a significant contributor to global warming and is strongly linked to adverse health outcomes. Produced by the incomplete combustion of fuels – emitted from large trucks, trains, and marine vessels – it is an air pollutant of particular concern to residents in urban areas. Sensors available on the market today are expensive, making black carbon... Read more

Sure, computers can be used to play grand-master level chess, but can they make scientific discoveries? Researchers at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory have shown that an algorithm with no training in materials science can scan the text of millions of papers and uncover new scientific knowledge.A team led by Anubhav Jain, a scientist in Berkeley Lab’s...

Applying artificial intelligence to self-driving cars to smooth traffic, reduce fuel consumption, and improve air quality predictions may sound like the stuff of science fiction, but researchers from the Lab’s Energy Analysis & Environmental Impacts Division have launched two research projects to do just that. For the full story:... Read more

October 8 marks the 4th annual National Hydrogen Day—a date that gives a nod to the atomic weight of hydrogen (1.008) and to the increasing role hydrogen fuel is playing nationally. Berkeley National Laboratory (Berkeley Lab) scientists are working every day on research that allows hydrogen to be produced, stored, and used in cleaner and even more efficient and affordable ways.Hydrogen fuel is...

Today, electric vehicles (EVs) make up just a small part of the U.S. road fleet, but they are gaining ground in some regions. While EVs hold promise for lowering costs and air pollutant emissions from auto travel, among other benefits, their growth raises questions about the changes needed to support this transition. How much charging infrastructure will be needed, and what role should utilities... Read more

In a Twitter Video, Anand Gopal of the International Energy Studies Group and the Energy Analysis & Environmental Impacts Division discusses the rapid expansion of car ownership in India, the anticipated impact this will have on greenhouse gas emissions, and the country’s move toward electric vehicles.https://twitter.com/macfound/status/1019990500319813632...

Li-ion battery development relies on the chemical reaction of the active elements in the electrode’s materials. A promising new strategy uses an unconventional element typically believed to be inactive. In a recent paper, ETA’s Wei Tong and Bryan McCloskey, and Wanli Yang of the ALS, reveal experimental evidence to confirm the contribution of this unconventional element. Read the full article...

Like a well-tended greenhouse garden, a specialized type of hydrogen fuel cell – which shows promise as a clean, renewable next-generation power source for vehicles and other uses – requires precise temperature and moisture controls to be at its best. If the internal conditions are too dry or too wet, the fuel cell won’t function well.But seeing inside a working fuel cell at the tiny scales... Read more
