• 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.

  • U.S. Power Sector is Halfway to Zero Carbon Emissions

    Concerns about climate change are driving a growing number of states, utilities, and corporations to set the goal of zeroing out power-sector carbon emissions. To date 17 states plus Washington, D.C. and Puerto Rico have adopted laws or executive orders to achieve 100% carbon-free electricity in the next couple of decades. Additionally, 46 U.S. utilities have pledged to go carbon free no later than 2050. Altogether, these goals cover about half of the U.S. population and economy.

  • Negative Emissions, Positive Economy

    The long-term goals of the Paris Agreement — keeping global warming well below 2 degrees Celsius and ideally 1.5 C in order to avert the worst impacts of climate change — may not be achievable by greenhouse gas emissions-reduction measures alone. Most scenarios for meeting these targets also require the deployment of negative emissions technologies (NETs) that remove carbon dioxide (CO2) from the atmosphere. Bioenergy with carbon capture and storage could help stabilize the climate without breaking the bank.

  • The U.S. Is Worried about Its Critical Minerals Supply Chains – Essential for Electric Vehicles, Wind Power and the Nation’s Defense

    When U.S. companies build military weapons systems, electric vehicle batteries, satellites and wind turbines, they rely heavily on a few dozen “critical minerals” – many of which are mined and refined almost entirely by other countries. Building a single F-35A fighter jet, for example, requires at least 920 pounds of rare earth elements that come primarily from China. That level of dependence on imports worries the U.S. government.
