Fuel Cell X-Ray Study Details Effects of Temperature and Moisture on Performance

To find the right balance of moisture and temperature in a specialized type of hydrogen fuel cell, Berkeley Lab scientists have used X-rays to explore the inner workings of its components at tiny scales.

Reimagining Hydrogen: A Small Molecule With Large-Scale Ideas

While hydrogen is often talked about as a pollution-free fuel of the future, especially for use in fuel cell electric vehicles, hydrogen can be used for much more than zero-emission cars. In fact, from enhancing the flexibility of the grid to greening agriculture, hydrogen could play a major role in a clean and resilient energy system.

Annual Wind Power Report Confirms Technology Advancements, Improved Project Performance, and Low Wind Energy Prices

Wind energy pricing for land-based, utility-scale projects remains attractive to utility and commercial purchasers, according to an annual report released by the U.S. Department of Energy and prepared by Berkeley Lab. Prices offered by newly built wind projects in the United States are averaging around 2¢/kWh, driven lower by technology advancements and cost reductions.

Shading and Lighting Retrofits Slash Energy Use in New York “Living Lab” Office Demonstration

By using advanced lighting and automated shades, Berkeley Lab scientists found that occupants on one floor of a high-rise office building in New York City were able to reduce lighting energy usage by nearly 80 percent in some areas. The dramatic results emerged at a “living laboratory” set up to test four sets of technologies on one 40,000 square-foot floor of a building.

A Seaweed Derivative Could Be Just What Lithium-Sulfur Batteries Need

Lithium-sulfur batteries have great potential as a low-cost, high-energy, energy source for both vehicle and grid applications. However, they suffer from significant capacity fading. Now scientists from the Lawrence Berkeley National Laboratory have made a surprising discovery that could fix this problem.

‘Expert in a suitcase’ Cuts Power Bills 10% in Small Commercial Buildings

The knowledge and expertise of a seasoned energy efficiency professional has been packed into a high-tech suitcase. The Sensor Suitcase is a portable case that contains easy-to-use sensors and other equipment that make it possible for anyone to identify energy-saving opportunities in small commercial buildings.

Berkeley Lab Helps California Get to Zero Net Energy Homes

California has established ambitious goals to reduce energy consumption in buildings, including a policy goal for all new residential buildings to be zero net energy (ZNE) by 2020. Now Berkeley Lab has launched two projects to help the state meet its ZNE building goals.

Not All Cool Pavements Are Created Equal

Cool pavements can help keep cities cool, right? Yes, but according to new research from Lawrence Berkeley National Laboratory, more reflective pavements have some unexpected drawbacks relative to conventional pavements when considering the entire life cycle of the materials.

Four Small Businesses to Collaborate with Berkeley Lab Through Small Business Vouchers

The U.S. Department of Energy announced that 38 small businesses will collaborate with national lab researchers through the Small Business Vouchers (SBV) pilot, including four that will work with Berkeley Lab in the areas of bioenergy and advanced manufacturing.

New Berkeley Lab Project Turns Waste Heat to Electricity

A new Berkeley Lab project seeks to efficiently capture waste heat and convert it to electricity, potentially saving California up to $385 million per year. With a $2-million grant from the California Energy Commission, Berkeley Lab scientists will work with Alphabet Energy to create a cost-effective thermoelectric waste heat recovery system.
