• Is Nuclear Energy the Way to Achieve Climate Goals?

    After decades out of fashion, a declaration to triple nuclear capacity at UN climate talks suggests a revival. Some say it’s necessary to help curb emissions, others call it a needless distraction.

  • “Energy Droughts” in Wind and Solar Can Last Nearly a Week, Research Shows

    Understanding the risk of compound energy droughts—times when the sun doesn’t shine and the wind doesn’t blow—will help grid planners understand where energy storage is needed most.

  • Innovative Long-Duration Energy Storage Project

    Argonne and Idaho National Laboratories have been selected by the U.S. Department of Energy for a project to validate CMBlu Energy’s battery technology for microgrid resilience and electric vehicle charging. U.S. Department of Energy selects national labs to validate the company’s battery technology for microgrid resilience and electric vehicle charging.

  • Seaworthy Solution Yields Green Energy, Fresh Water

    Engineers have refined a model that not only cultivates green energy, but also desalinates ocean water for large, drought-stricken coastal populations.By pumping seawater to a mountaintop reservoir and then employing gravity to send the salty water down to a co-located hydropower plant and a reverse osmosis desalination facility, science can satisfy the energy and hydration needs of coastal cities with one system.

  • Modeling Geothermal Systems’ Viability

    Geothermal power has a lot of promise as a renewable energy source that is not dependent on the sun shining or the wind blowing, but it has some obstacles to wide adoption. One challenge is that a limited number of locations in the U.S. naturally have the right conditions: hot rock relatively close to the surface and with plentiful groundwater to heat up. Web tool looks belowground for an economically viable renewable energy source.

  • Non-powered Dams Offer Opportunity for Clean Energy

    The era of building big dams may be over in the United States, but hydroelectricity still has a significant and untapped role to play in the nation’s energy future. Trouble is, 97 percent of U.S. dams don’t make electricity. A new tool could help tap that resource.

  • A First: For Six Days in a Row, Portugal Ran on 100% Renewables

    For nearly a week, the country of 10 million met customer needs with wind, hydro and solar — a test run for operating the grid without fossil fuels.

  • New Battery Tech from Sweden Offers Alternative to Critical Materials from China

    New sodium-ion battery is safer and more cost-effective and sustainable than conventional nickel, manganese, and cobalt (NMC) or iron phosphate (LFP) chemistries, and is produced with minerals such as iron and sodium that are abundant on global markets.

  • Move Over Lithium-Ion: Zinc-Air Batteries a Cheaper and Safer Alternative

    New research shows batteries built from zinc and air could be the future of powering electric vehicles. The project tested zinc-air batteries using a combination of cheaper, safer and sustainably sourced materials, which allowed for improved lifespan and performance.

  • Fast Reactor Technology Is an American Clean, Green and Secure Energy Option

    Pivotal partnerships between industry and national laboratories steer advances that will help combat climate change. Companies in the nuclear industry work closely with national labs and the DOE Fast Reactor Program to develop next-generation nuclear reactors.

  • Engineers Develop an Efficient Process to Make Fuel from Carbon Dioxide

    The approach directly converts the greenhouse gas into formate, a solid fuel that can be stored indefinitely and could be used to heat homes or power industries.

  • Fueling the Future of Fusion Energy

    Long considered the ultimate source of clean energy, nuclear fusion promises abundant electrical power without greenhouse gas emissions or long-lasting radioactive waste. The process has fueled the core of the sun for more than four billion years – with billons more to go. Nore scientists are joining the global pursuit of harnessing that reaction.

  • Modular Dam Design Could Accelerate the Adoption of Renewable Energy

    Researchers have developed a new modular steel buttress dam system designed to resolve energy storage issues hindering the integration of renewable resources into the energy mix. The m-Presa modular steel buttress dam system cut dam construction costs by one-third and reduce construction schedules by half.

  • Finland: Pipeline Leak Likely Caused by 'External Activity'

    Damage to an underwater gas pipeline and telecommunications cable connecting Finland and Estonia may have been a deliberate act, according to Finnish authorities.

  • Using Petroleum Reservoirs to Store Carbon

    Oil and gas produced from reservoirs are traditionally thought of as sources of carbon dioxide and other greenhouse gases. In recent years, scientists in government and industry have been looking more at oil and gas reservoirs as places to store the very carbon that was previously taken out of the reservoirs. Injecting carbon dioxide into oil reservoirs also increases oil production in areas that have already produced a lot of oil.
