Video: Designing diamond batteries powered by nuclear waste
Spent graphite waste stored at the U.K.’s Berkeley nuclear power plant, decommissioned in 1989, can be put to use as the basis for diamond batteries.
Tri-State pivots to renewable energy as coal plants close
Combined, the new generating resources will result in more than 1 gigawatt of renewable resource capacity added to Tri-State’s power supply portfolio by 2024.
Canister designed for transfer of hotter used nuclear fuel
Each canister accepts heat loads of up to 50 kW so that used fuel can be transferred to secure dry storage after a shorter period of time.
Video: Battery generates clean power for rural users
The reusable battery is assembled with commonly available materials – iron, water, coffee filters and carbon felt – and can power an LED bulb for five hours or charge a cell phone.
Analyze wind system costs with open-source model
An open-source model developed by U.S. National Renewable Energy Laboratory engineers is available to help designers of land-based wind energy systems estimate balance-of-system costs.
Watt-Flex cartridge heaters offer continuous coil heating technology
Watt-Flex heaters have a unique continuous heating coil which creates a uniform temperature profile.
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.
