• Better Batteries for Grid-Scale Energy Storage

    Molten sodium batteries have been used for many years to store energy from renewable sources, such as solar panels and wind turbines. However, commercially available molten sodium batteries, called sodium-sulfur batteries, typically operate at 520-660 degrees Fahrenheit. Sandia Lab’s new molten sodium-iodide battery, using low- cost materials, operates at a much cooler 230 degrees Fahrenheit instead.

  • A 10-Year Look at the Battery Supply Chain in America

    A new report offers a detailed view of America’s EV battery supply chain over the last decade. The insights offered can help regulators and other key decisionmakers plan for the future growth of electric vehicles (EVs) in the U.S. This is important, because EVs can help put America on the path toward a clean energy economy. but the supply chain behind them is not fully understood.

  • Global Approach Is Needed on Battery Regulation

    New EU regulations on batteries could offer a huge boost to the global decarbonization mission – but only if the EU leverages its political and economic weight to ensure a fairer global marketplace.

  • No Excuse to Continue Reliance on Fossil Fuels: Nano-Technologist

    One of the leading thinkers in nano-science has called on the energy materials community to help finally put an end to the world’s reliance on fossil fuels. The expertchallenges the scientific community to lead the world away from a reality where fossil fuels still account for 80 percent of the energy mix.

  • Cold Weather Cost New England Electric Customers Nearly $1.8 Billion in One Month

    Constraints in the supply of natural gas have led to nearly a quarter of all unscheduled power plant outages in New England in the last decade. A new study suggests ways to mitigate fuel shortages.

  • Exploring Hydrogen Storage

    Hydrogen is emerging as a low-carbon fuel option for transportation, electricity generation, manufacturing applications and clean energy technologies that will accelerate the United States’ transition to a low-carbon economy. However, a key challenge is to ensure the safe and effective storage of hydrogen.

  • California Is Planning Floating Wind Farms Offshore to Boost Its Power Supply – Here’s How They Work

    Northern California has some of the strongest offshore winds in the U.S., with immense potential to produce clean energy. But it has a problem. Its continental shelf drops off quickly, making building traditional wind turbines directly on the seafloor costly if not impossible. A solution has emerged that’s being tested in several locations around the world: making wind turbines that float.

  • Bipartisan Legislation Addresses Dams’ Safety, Hydropower

    There are more than 90,000 dams in the U.S., including 6,000 “high-hazard” dams with poor, unsatisfactory, or unknown safety ratings, posing threats to life and property. Hydropower is responsible for 6 percent of electricity production in the U.S.— and more than 90 percent of the U.S. current electricity storage capacity — but the dams which generate this power are aging and need upgrades.

  • Can Europe Escape Gazprom's Energy Stranglehold?

    When it comes to gas supplies to the EU, Russia’s state-owned corporation Gazprom steps on the brakes, and natural gas reservoirs are unusually low. Is Russia building up political pressure in order to push through the operation of the Nord Stream 2 pipeline?

  • Producing Geothermal Energy Diminishes Earthquake Risk

    Researchers studying the 5 July 2019 magnitude-7.1 earthquake in Ridgecrest, California found that none of the thousands recorded aftershocks in the region were seen in the Coso geothermal field, an area only about ten kilometers away. Now they know why: The development of geothermal energy reduces underground stress and mitigates risks of large earthquakes.

  • Recent Technology Cost Forecasts Underestimate Pace of Technological Change

    A comparison of observed global energy technology costs, with forecasts generated by models and forecasts predicted by human experts, showed that both forecasting methods underestimated cost reductions. This suggests that decisions based on forecasts may be overestimating the cost of climate mitigation and points to the need to further improve forecasting methods.

  • Why “Nuclear Batteries” Offer a New Approach to Carbon-Free Energy

    Much as large, expensive, and centralized computers gave way to the widely distributed PCs of today, a new generation of relatively tiny and inexpensive factory-built reactors, designed for autonomous plug-and-play operation similar to plugging in an oversized battery, is on the horizon. These microreactors, trucked to usage sites, could be a safe, efficient option for decarbonizing electricity systems.

  • Better Method to Predict Offshore Wind Power

    Offshore wind is maturing into a major source of renewable energy, and is projected to grow 15-fold by 2040 to become a $1 trillion industry. Researchers have developed a machine learning model using a physics-based simulator and real-world meteorological data to better predict offshore wind power.

  • Physics-Based Instruction Leads to Success for Geothermal Drilling

    Using the earth’s subsurface heat to change water to steam and power generators to produce electricity is not a new idea. The first large-scale geothermal electricity-generating plant opened in the U.S. in 1960 and has grown to become the most significant energy complex of its kind in the world. But while advances in technology have improved energy production efficiency, one aspect of tapping this renewable resource is still highly cost-prohibitive to those wanting to invest in it: Drilling into the earth.

  • Hydropower’s Evolving Value to the Grid and Energy Storage

    Across the United States, hydroelectric dams are capturing energy from river water to create electricity that powers everything from street lights to mega industrial plants. Hydropower represents 41 percent of all renewable energy generated across the nation and is a key element of a flexible, resilient electric grid. But in some parts of the country, operations at dams are changing.
