• ENERGY SECURITYNuclear Electricity Supply Would Be Less Vulnerable to Attack Than Renewables

    By Graham Cummings

    Renewable energy generation is not as robust in the face of enemy attack as it looks. Nuclear power, even though it would probably be concentrated in a few large generating stations, should in fact be a little more dependable in wartime.

  • ENERGY SECURITYRanking the Feasibility of Converting 245 U.S. Coal Plants to Nuclear

    An assessment ranks the feasibility of converting 245 operational coal power plants in the U.S. into advanced nuclear reactors. This is the most comprehensive coal-to-nuclear analysis to date, and it could help policymakers and utilities plan how to meet climate targets.

  • BATTERIESBoosting Battery Research

    Most Americans don’t leave home without at least one lithium battery-powered device, and someday, the house itself may have a battery backup. Scientists are working to make these large backup batteries less expensive, hold more energy and be less prone to bursting into flame.

  • ENERGY SECURITYHow Would a Switch to Nuclear Affect Electricity Prices for Households and Industry?

    By Roger Dargaville

    In a free market, it is very unlikely nuclear could be competitive. But if a future Australian government were to bring nuclear into the mix, energy costs for residential and especially industrial customers would very likely increase.

  • ENERGY SECURITYUtah FORGE Achieves Crucial Geothermal Milestone

    By Brian Maffly

    In $218 million DOE-funded research project, scientists aim to make enhanced geothermal a key part of world’s energy portfolio. “The ability to tap more of the Earth’s natural heat through enhanced geothermal systems will expand access to affordable, secure and resilient clean energy for everyone,” say one expert.

  • ENERGY SECURITYSome Countries Could Meet Their Total Electricity Needs from Floating Solar Panels

    Researchers calculated the global potential for deploying low-carbon floating solar arrays. The researchers looked at nearly 68,000 lakes and reservoirs around the world which were no more than 10km from a population center, not in a protected area, didn’t dry up and didn’t freeze for more than six months each year. The potential annual electricity generation from FPV on these lakes was 1302 terawatt hours (TWh), around four times the total annual electricity demand of the UK.

  • HYDROGEN HAZARDSWhat Are the Risks of Hydrogen Vehicles in Tunnels?

    By Falko Schoklitsch

    In addition to electric vehicles, hydrogen-powered vehicles are also seen as an alternative to conventionally powered vehicles. Scientists have analyzed the risk and damage potential of hydrogen vehicles in tunnels and derived recommendations. Their conclusion? Any damage would be extensive, but its occurrence is unlikely.

  • NUCLEAR RISKSFacing a Potentially Warmer, Drier Washington State, Scientists Develops Plans to Be Sure Nuclear Power Plants Stay Cool

    By Kristen Mally Dean

    Waterways — tried and true cooling sources for nuclear power plants — could get warmer due to global climate change. Washington is planning ahead. Argonne scientists will use Gateway for Accelerated Innovation in Nuclear funding from the U.S. Department of Energy to work with Washington’s Energy Northwest on climate-ready nuclear reactor designs.

  • ENERGY SECURITYSmall Hydroelectric Plants Could Provide Emergency Power During Outages

    Idaho National Laboratory (INL) is seeking a hydropower utility to collaborate on a case study, funded by the U.S. Department of Energy’s Water Power Technologies Office (WPTO), to understand how small hydroelectric plants operating at 10 megawatts or less can be upgraded to provide emergency power to critical loads (e.g., hospitals and emergency service providers) during outages.

  • BATTERIESMaking Batteries Takes Lots of Lithium: Almost Half of It Could Come from Pennsylvania Wastewater

    By Brandie Jefferson

    Most batteries used in technology like smartwatches and electric cars are made with lithium that travels across the world before even getting to manufacturers. But what if nearly half of the lithium used in the U.S. could come from Pennsylvania wastewater?

  • SUSTAINABLE COMPETITIVENESSSecuring Competitiveness of Energy-Intensive industries Through Relocation: The Pulling Power of Renewables

    Countries with limited potential for renewables could save up to 20 percent of costs for green steel and up to 40 percent for green chemicals from green hydrogen if they relocated their energy-intensive production and would import from countries where renewable energy is cheaper.

  • ENERGY SECURITYRivers Are the West’s Largest Source of Clean Energy. What Happens When Drought Strikes?

    By Syris Valentine

    With rivers across the West running low, utilities must get creative if they are to meet demand without increasing emissions.

  • ENERGY SECURITYSubterranean Storage of Hydrogen

    By Mollie Rappe

    Hydrogen is an important clean fuel: It can be made by splitting water using solar or wind power, it can be used to generate electricity and to power heavy industry, and it could be used to energize fuel-cell-based vehicles. Sandia scientists are using computer simulations and laboratory experiments to see if depleted oil and natural gas reservoirs can be used for storing this carbon-free fuel.

  • ENERGY SECURITYHow Texas Is Playing a Major Role in the Race to Develop Clean Energy Technologies

    By Alejandra Martinez

    The federal government is pouring billions of dollars into developing clean power sources. In this conversation hosted by The Texas Tribune in Houston, panelists discussed how Texas companies are playing a major role in emerging technologies like hydrogen and geothermal.

  • POWER GRIDIn the Central U.S., an Electric Grid Bottleneck Persists

    By Robert Zullo

    Forty-five million people live in the area managed by the Midcontinent Independent System Operator, the organization that runs a massive portion of the North American electric grid running from Manitoba, Canada, to the Gulf of Mexico. Where the northern part of the system meets the southern end — a narrow corridor that traverses a corner of southeast Missouri and northeastern Arkansas — there’s a bottleneck that can hurt electric customers and create major inefficiencies on both sides of the divide.
