• Combining old and new to create a novel power grid cybersecurity tool

    An innovative R&D project that combines cybersecurity, machine learning algorithms and commercially available power system sensor technology to better protect the electric power grid has sparked interest from U.S. utilities, power companies and government officials. Creating innovative tools and technologies to reduce the risk that energy delivery might be disrupted by a cyber incident is vital to making the nation’s electric power grid resilient to cyber threats.

  • Microgrids have a large impact

    As many as 1.3 billion people lack access to electrical power. Engineers make strides in technologies that promise to make electrical power more accessible almost anywhere on the planet. One of his solutions is microgrids, which provide independent power generation and storage systems capable of operating as mobile or standalone systems or as a supplemental part of larger conventional power grids.

  • Metal-eating microbes are cost-effective for recycling rare earth elements

    Today’s high-tech devices usually contain components made of rare earth elements (REEs), a class of metallic elements including neodymium and dysprosium. Despite this demand, and despite the fact that REEs are relatively common in the earth’s crust, REEs are difficult to obtain, and the U.S. currently does not produce a domestic supply. This scarcity of domestic REEs leaves manufacturers of everything from cellphones and computers to wind turbines and telescope lenses vulnerable to supply disruptions. have developed an economical way to recycle REEs using a bacterium called Gluconobacter oxydans.

  • Sea level rise requires new forms of decision making

    U.S, cities facing sea level rise need to look beyond traditional strategies for managing issues such as critical erosion and coastal squeeze, according to new research. Civil society initiatives must now play a crucial role in adapting society to climate change, and decision makers must seriously consider the tradeoff among three options: sea wall; beach-nourishment; and relocating coastal infrastructure.

  • Kremlin hackers infiltrated the most secure German government communication network

    The German government yesterday (Wednesday) confirmed that it had suffered a large cyberattack which infiltrated federal computer networks in search of sensitive information. Anonymous German law enforcement sources said that the Russia hacking group APT28, aka Fancy Bear, had placed malware in a government network and infiltrated both the Foreign Ministry and the Defense Ministry. Fancy Bear, which is one of the hacking groups operated by the GRU (Russia’s military intelligence branch), conducted the 2016 hacking campaign of the DNC and the Hillary Clinton campaign. The Russian government hackers managed to infiltrate the German government’s “Informationsverbund Berlin-Bonn” (IVBB) network, a communication network which was specially designed as a secure communications platform.

  • Flood risk for Americans is greatly underestimated

    A new study has found that forty-one million Americans are at risk from flooding rivers, which is more than three times the current estimate—based on regulatory flood maps—of thirteen million people. The study is based on a new high-resolution model that maps flood risk across the entire continental United States, whereas the existing regulatory flood maps produced by the Federal Emergency Management Agency (FEMA) cover about 60 percent of the continental United States. Avoiding future losses is particularly important as average flood losses in the United States have increased steadily to nearly $10 billion annually.

  • Drawing industry attention to ensuring grid reliability

    Grid reliability depends on controlling the power system frequency so that it remains within pre-established, safe operating bounds. Reliability is threatened when a large electric generator or generators experiences a problem and automatically disconnects from the power system; the loss of generation causes an immediate decline in power system frequency. If the remaining, still-connected generators do not respond to rapidly arrest the decline in frequency, power system frequency may decline below established, safe operating bounds and trigger automatic, emergency load shedding to avoid a cascading blackout. A report for FERC details six recommendations to reduce likelihood of blackouts.

  • It pays to build to withstand disasters

    For every dollar the government spends to make existing buildings more resistant to wildfires, earthquakes, floods and hurricanes, $6 is saved in property losses, business interruption and health problems, according to a new study. The study also found that for every $1 spent to exceed building codes and make structures more hazard-resistant in the future, $4 would be saved. In all, over the next 75 years, these measures could prevent 600 deaths, 1 million injuries and 4,000 cases of post-traumatic stress disorder, the report concludes.

  • Sea levels rising more than previously expected

    Studying twenty-five years’ worth of satellite data, scientists paint a grim picture of global warming. Sea levels are going up at a faster rate each year, and even sooner than projected. The calculate that at the current pace, the total sea level rise could be twice as high as previous projections by 2100.

  • Helping Georgia companies prepare for natural disasters

    The Georgia Manufacturing Extension Partnership (GaMEP) is seeking eligible manufacturers to participate in a disaster assistance program designed to help companies that are located in the state’s coastal areas assess their preparedness and develop operational solutions to minimize the impact of future hurricanes and other natural disasters.

  • U.S. seeks to boost domestic production of 35 critical minerals

    The U.S. Department of the Interior (DOI) last week announced it was seeking public comment by 19 March 2018 on a draft list of minerals considered critical to the economic and national security of the United States. The draft list of minerals that DOI published last week as critical to the United States includes thirty-five mineral commodities. A “critical mineral” is a mineral identified to be a non-fuel mineral or mineral material essential to the economic and national security of the United States, the supply chain of which is vulnerable to disruption, and that serves an essential function in the manufacturing of a product, the absence of which would have significant consequences for the economy or national security.

  • Meet the new “renewable superpowers”: nations that boss the materials used for wind and solar

    Imagine a world where every country has not only complied with the Paris climate agreement but has moved away from fossil fuels entirely. How would such a change affect global politics? The twentieth century was dominated by coal, oil and natural gas, but a shift to zero-emission energy generation and transport means a new set of elements will become key. Solar energy, for instance, still primarily uses silicon technology, for which the major raw material is the rock quartzite. Lithium represents the key limiting resource for most batteries – while rare earth metals, in particular “lanthanides” such as neodymium, are required for the magnets in wind turbine generators. Copper is the conductor of choice for wind power, being used in the generator windings, power cables, transformers and inverters. In considering this future it is necessary to understand who wins and loses by a switch from carbon to silicon, copper, lithium, and rare earth metals.

  • Studying Caribbean hurricane damage to reduce hurricane risks worldwide

    The biggest natural disaster to ever hit the Caribbean island of Dominica is now likely to provide guidelines for reducing the risk globally of disaster from hurricanes. Scientists are surveying the damage to Dominica’s landscape, infrastructure and communities following the destruction caused by Hurricane Maria in 2017. Dominica was devastated by the hurricane last September which left 68 people dead or missing. The hurricane registered as Category 5 on the Saffir-Simpson scale, with maximum wind speeds of 260 km/h.

  • Mexico’s September 2017 tremor highlights successes of seismic early warning system

    Mexico’s earthquake early warning system gave Mexico City’s residents almost two minutes of warning prior to the arrival of strong seismic waves from the 7 September 2017 Tehuantepec earthquake centered off the southern coast of Mexico, according to a new study. The magnitude 8.2 earthquake is the largest earthquake detected by the alert system, known as SASMEX, since it began operations in 1993. SASMEX also sent an alert for the magnitude 7.1 Morelos earthquake that occurred on 19 September. The alerts highlighted how some recent improvements to the system may help decrease the time needed to receive, detect and broadcast the alerts, but they also point to places where the system can improve in the future.

  • Cape Town water crisis should serve as a “wakeup call to all major U.S. cities”: Expert

    Cape Town, South Africa is hurtling towards a water apocalypse with “Day Zero” — when authorities will turn off the taps — pegged for the first half of April. The crisis, which has placed the city in peril, was caused by years of draught, insufficient and aging infrastructure, and population growth. To find out what this means for Cape Town residents and if a similar disaster could strike Phoenix, ASU Now turned to Dave White, a professor in the School of Community Resources and Development, a unit within ASU’s College of Public Service and Community Solutions and director of Decision Center for a Desert City.
