Madison Gas and Electric (MGE) is receiving a $5.5 million grant from the U.S. Department of Energy. MGE will use the grant to install technologies to boost efficiency, enhance service and improve reliability for customers.
The stimulus grant will help fund the following projects, which will begin next month:
Advanced metering infrastructure
MGE will install meters capable of two-way communication for all large commercial and industrial customers. The equipment monitors and analyzes customers’ energy consumption patterns on an hourly, daily and seasonal basis. The information will be used to educate customers about their energy use and how they can conserve energy and lower emissions. The meters also will be used for outage notification and tracking power quality.
Plug-in hybrid electric vehicles support
MGE will also install a network of up to 18 public and 25 residential charging stations for electric and electric hybrid vehicles in the Madison area. MGE will study the impacts of vehicle charging on the electric power grid and on home energy use and demand.
MGE will also install new distribution/management capabilities. During an outage, MGE system operators will be able to quickly identify the best options for restoring and rerouting power to reduce outage times.
MGE generates and distributes electricity to 138,000 customers in Dane County, Wis., and purchases and distributes natural gas to 142,000 customers in seven south-central and western Wisconsin counties. MGE’s parent company is MGE Energy (Nasdaq: MGEE). The company’s roots in the Madison area date back more than 150 years.
Materials scientists at the University of Wisconsin-Madison have taken the help of piezoelectric effect to harness random energy available in the atmosphere to turn water into usable hydrogen fuel. It might prove a simple, efficient method to recycle waste energy. The research team is led by Huifang Xu, who is a UW-Madison geologist and crystal specialist. They took nanocrystals of zinc oxide and barium titanate. These two nanocrystals were put in water. When these crystals received ultrasonic vibrations, the nanofibers flexed and catalyzed a chemical reaction. This whole process resulted in splitting the water molecules into hydrogen and oxygen.
“This study provides a simple and cost-effective technology for direct water splitting that may generate hydrogen fuels by scavenging energy wastes such as noise or stray vibrations from the environment,” the authors write in a new paper, published in the Journal of Physical Chemistry Letters. “This new discovery may have potential implications in solving the challenging energy and environmental issues that we are facing today and in the future.”
The researchers, led by UW-Madison geologist and crystal specialist Huifang Xu, grew nanocrystals of two common crystals, zinc oxide and barium titanate, and placed them in water. When pulsed with ultrasonic vibrations, the nanofibers flexed and catalyzed a chemical reaction to split the water molecules into hydrogen and oxygen.
But scientists didn’t utilize this electrical energy straightaway. They use this energy in breaking the chemical bonds in water to split oxygen and hydrogen. Xu explains, “This is a new phenomenon, converting mechanical energy directly to chemical energy.” Xu calls it a piezoelectrochemical (PZEC) effect. Why it seems that scientists are beating around the bush? Because chemical energy of hydrogen fuel is more stable than the electric charge. Storage of hydrogen fuel is easy and would not lose potency over time.
With the right technology, Xu foresees this method to be utilized where small amount of power is needed. Now we can imagine charging a cell phone while taking our morning walk or we can enjoy cool breeze that can power street lights. Xu says, “We have limited areas to collect large energy differences, like a waterfall or a big dam. But we have lots of places with small energies. If we can harvest that energy, it would be tremendous.”
