• Guiding Research Direction for Grid-Forming Inverters

    Power electronics—including the inverters that interface solar, wind, battery energy storage, and electric vehicles—are on track to gradually, or even entirely, displace traditional generation. In doing so, inverters will inherit new responsibilities and introduce a new set of challenges.

  • Capturing Potable Water from Air

    DARPA recently awarded five contracts and selected one government partner to develop technology to capture potable water from the air in quantities sufficient to meet critical DoD needs, even in extremely dry climates. The Atmospheric Water Extraction (AWE) performers aim to meet clean water needs of deployed troops, even in austere environments.

  • It’s Electrifying! Earth Could Be Entirely Powered by Sustainable Energy

    Can you imagine a world powered by 100 percent renewable electricity and fuels? It may seem fantasy, but a collaborative team of scientists has just shown this dream is theoretically possible – if we can garner global buy-in.

  • Mitigating Coastal Flooding, Erosion and Storm Damage

    Sea level rise and wave-induced flooding during increasingly frequent storm events threaten sustainability of the more than 1,700 Department of Defense (DoD) managed military installations in coastal areas worldwide. Current DoD coastal protection measures, including bulkhead and coastal seawalls, may reflect wave energy, exacerbate flooding, create downstream sediment loss, and restrict water exchange. DARPA’s Reefense program aims to develop novel hybrid biological and engineered reef-mimicking structures to mitigate wave and storm damage and reduce the ecological impact of current coastal protection measures.

     

  • Nuclear Waste Storage Canisters to Be Tested

    Three 22.5-ton, 16.5-feet-long stainless-steel storage canisters, with heaters and instrumentation to simulate nuclear waste so researchers can study their durability, will be tested at Sandia National Lab. The three canisters have never contained any nuclear materials. They will be used to study how much salt gathers on canisters over time. Sandia will also study the potential for cracks caused by salt- and stress-induced corrosion with additional canisters that will be delivered during the next stage of the project.

  • High Rises Made of Timber

    With an increasing demand for a more sustainable alternative for high-rise construction, new points to timber as a sustainable and effective way to make tall, high-density, and renewable buildings. Tall mass-timber buildings are a safe and sustainable alternative for high-rise construction,

  • How Disasters Can Spur Resilience in the Gulf

    Communities in the Gulf of Mexico are all too familiar with the whims of nature and power of the sea. This year’s hurricane season brought power outages, heavy rain, downed trees, property damage, and death and injury. As disasters cascade and compound, progress toward resiliency is made by people working together and using science to decide next steps. 

  • Making Our Infrastructure Safer

    Saurabh Amin, a systems engineer at MIT, focuses on making transportation, electricity, and water infrastructure more resilient against disruptions. “There are a lot of commonalities among these networks — they are built and operated by human actors, but their functionality is governed by physical laws. So, that is what drives me forward,” Amin says.

  • Novel Chemical Process a First Step to Making Nuclear Fuel with Fire

    Uranium dioxide, a radioactive actinide oxide, is the most widely used nuclear fuel in today’s nuclear power plants. A new “combustion synthesis” process recently established for lanthanide metals—non-radioactive and positioned one row above actinides on the periodic table—could be a guide for the production of safe, sustainable nuclear fuels.

  • Improving Water Security for People in Africa and Asia by 2024

    New funding from the Foreign, Commonwealth & Development Office (FCDO) will support global research and practice to improve water security for 10 million people in Africa and Asia. The FCDO’s grant to the University of Oxford will now extend to 2024 and increase to £22.5 million, to support the REACH program improve water security by delivering world-class science to transform policy and practice.

  • Guidance Will Improve Critical Infrastructure Resilience

    It is easy to understand the importance of our “critical infrastructure,” such as telecommunications, energy, transportation, and emergency services, but what’s often overlooked are the underlying technologies that enable them. DHS S&T is doing something about it.

  • Students of Nuclear Security Have a Problem. Here’s How to Help Them.

    Radioactive materials are attractive targets to thieves and other bad actors. These are rare finds, valuable on the black market and relatively easy to weaponize. New security professionals rarely learn practical skills for protecting these targets until they are on the job at nuclear power plants, research reactors, processing plants and other nuclear facilities.

  • Oil Feld Operations Likely Triggered Earthquakes in California Near San Andreas Fault

    The way companies drill for oil and gas and dispose of wastewater can trigger earthquakes, at times in unexpected places. California was thought to be an exception, a place where oil field operations and tectonic faults apparently coexisted without much problem. Now, new research shows that the state’s natural earthquake activity may be hiding industry-induced quakes.

  • Study Identifies Reasons for Soaring Nuclear Plant Cost Overruns in the U.S.

    Analysis points to ways engineering strategies could be reimagined to minimize delays and other unanticipated expenses. Many analysts believe nuclear power will play an essential part in reducing global emissions of greenhouse gases, and finding ways to curb these rising costs could be an important step toward encouraging the construction of new plants.

  • Putting Nuclear Reactors in Space

    A new agreement hopes to speed along a nuclear reactor technology that could be used to fuel deep-space exploration and possibly power human habitats on the Moon or Mars.
