Adding salt to a road before a winter storm changes when ice will form. Researchers at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) have applied this basic concept to develop a new method of heating and cooling. The technique, which they have named “ionocaloric cooling,” is described in a paper published Dec. 23 in the journal Science. Ionocaloric cooling... Read more

This article was adapted from a release developed by the National Renewable Energy Laboratory and was initially published at the Berkeley Lab News Center. Stor4Build is a new consortium on energy storage for buildings that will accelerate the growth, optimization, and deployment of storage technologies. The consortium will be co-led by the U.S. Department of Energy’s (DOE’s) Lawrence Berkeley... Read more

Ravi Prasher, associate laboratory director of the Energy Technologies Area and senior scientist in the Thermal Energy Group at Lawrence Berkeley National Laboratory (Berkeley Lab), will receive the 2022 Heat Transfer Memorial Award from the American Society of Mechanical Engineers (ASME). The prestigious award, established in 1959, recognizes outstanding contributions to the field of heat... Read more

Every year, 50% of the energy produced worldwide from coal, oil, natural gas, nuclear, and renewable energy sources is lost as heat. This untapped resource could be a promising additional source of useful energy, and for decades, scientists have worked to develop efficient systems to convert waste heat to electric power. In a recent study published in Joule, Berkeley Lab researchers developed a... Read more

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... Read more

With a $2-million grant from the California Energy Commission (CEC), Berkeley Lab has developed a cost-effective thermoelectric waste-heat recovery system to reduce electricity-related carbon emissions. Industries such as the glass, cement, power, and steel sectors expel a huge amount of high-temperature waste heat. Converting this waste heat cost effectively to electricity can provide a...

With rising interest in backup power, storage of solar energy, and electric vehicles, the race is on to improve the performance of rechargeable lithium batteries. A Berkeley Lab team has developed an easy, fast, and inexpensive method to measure battery performance. Led by Ravi Prasher and Sean Lubner of the Energy Technologies Area, the new technique uses thermal waves to measure local lithium... Read more

Leaders profiled in Department of Energy feature The future of energy depends on our ability to store it reliably, cheaply, and safely — whether to power electric vehicles, our buildings and factories, or to contribute to the clean grid of the future. Researchers at Lawrence Berkeley National Laboratory (Berkeley Lab) -- including three lead scientists recently profiled by the Department of... Read more

Heating and cooling buildings is a large part of global energy demand and a significant source of CO2 and greenhouse gas emissions, and in the coming decades the energy demand for heating and cooling - also known as thermal energy - is expected to grow considerably. Scientists and engineers have made many advances in lowering building energy demand by improving energy efficiency in building... Read more

Researchers from the Massachusetts Institute of Technology (MIT), Stanford University and Lawrence Berkeley National Laboratory (Berkeley Lab) — including Ravi Prasher — collaborated to write an article on energy, which was recently awarded the best peer-reviewed article for general readers by the American Energy Society. Prasher, associate laboratory director of the Energy Technologies Area... Read more

Understanding how matter interacts with light – its optical properties – is critical in a myriad of energy and biomedical technologies, such as targeted drug delivery, quantum dots, fuel combustion, and cracking of biomass. But calculating these properties is computationally intensive, and the inverse problem – designing a structure with desired optical properties – is even harder. Now... Read more

The Bay Area Battery Summit (BABS) just concluded its sixth annual conference, which was held virtually on November 17-18. This year, the two-day conference went beyond batteries and focused on catalyzing collaboration to drive innovation among key players in energy storage. The summit brought together leading researchers and policymakers, pioneering companies and startups, as well as innovative... Read more

The Energy Storage & Distributed Resources Division (ESDR) announced the formation of the Thermal Energy Group earlier this month. ESDR now encompasses six groups spanning a diverse set of research areas ranging from energy conversion to grid integration, all of which are part of the Energy Technologies Area (ETA) at Lawrence Berkeley National Laboratory (Berkeley Lab). The group will be led... Read more
