Tri-State plans to shutter coal-fired power plants
The wholesale generating and transmission cooperative has long favored coal to generate electricity for its 46-member network of electric distribution companies.
Wind turbine giant plans carbon-free future
Vestas plans to become a carbon-neutral company by 2030 by reducing carbon dioxide emissions throughout its operations as well as its supply chain.
How DC motor starters operate
Starting a DC motor poses unique challenges. DC motor starters allow a DC motor or motor-controlled device to be turned on or off.
Fuel cell vs battery: Cold weather effects on bus range
A loss in range as temperatures drop 50° to 60° F to 22° to 2° F is greater for battery electric buses than for fuel cell electric buses.
Re-engineered cathode elevates lithium-sulfur battery efficiency
A new lithium-sulfur battery design proved stable for more than 200 cycles at a Coulombic efficiency above 99%.
New disconnect standby switch for light commercial HVAC components
Marketair introduced a new disconnect standby switch with a standby portable generator receptacle and a three-position toggle switch to help expedite power restoration to light commercial air conditioners and heat pump condensers during brownouts and power outages.
Wind repowering project gets under way with new turbines and towers
The repowering project consists of replacing nacelles, towers and blades for 118 turbines that will have 108 m long blades on 80 m towers.
Watch: A stretch for silicon solar cells
In pursuit of a pliable power source, researchers successfully imparted ultrastretchability to conventionally rigid but highly efficient monocrystalline silicon solar cells.
Highview Power to build cryo-energy storage plant in Vermont
Highview Power and Encore Renewable Energy are codeveloping a long-duration energy storage system in northern Vermont. This facility will be the first of its kind in the United States providing a minimum capacity of 400MWh.
Engineering safety and performance into the lithium ion battery
By optimizing material combinations for electrodes as well as the electrolyte, battery safety and performance can both be realized.
New formula boosts bifacial solar cell performance
The method calculates the power production gains and cost savings that can be realized with the latest double-sided photovoltaic technologies.
NRC grants an early site permit for a possible SMR
The Tennessee Valley Authority won approval for an early site permit from the Nuclear Regulatory Commission to potentially build and operate small modular nuclear reactors.
Holey photovoltaics! Making silicon solar cells transparent
Punching microholes in crystalline silicon wafers imparts transparency to solar cells and opens new applications in building-integrated photovoltaics, vehicles and personal electronics.
Novel HVAC and building efficiency projects are targeted by Oak Ridge
The Energy Department said that the 127 million buildings in the United States consume nearly 40% of the nation’s total energy at a cost of $415 billion annually.
Watch: Safety engineers use high-speed cameras to capture arc fault explosions
Data from the Sandia-led tests will enable development of a computer model that will predict an arc fault’s zone of influence.
Watch the flight of the first commercial electric plane
An all-electric commercial passenger aircraft fitted with a lithium battery backed propulsion system has taken its inaugural flight.
A deep geothermal plant in Eden secured
A 10 year campaign secured £16.8 million in funds to complete the first phase of Eden’s geothermal heat and power project.
DOE puts dollars toward pebble bed-reactor design work
The project will focus on cutting costs through underground construction, the use of pooled off-site resources and simplified passive safety systems.
These nukes just got a green light for an 80-year service life
This marks the first time the NRC has issued renewed licenses authorizing reactor operation from 60 to 80 years.
Watch the unveiling of a new battery electric vehicle for European markets
The 400 km-range vehicle will feature a modular battery system with a capacity up to 720 kWh, which can be tailored to match different customers’ needs.
