Power plant siting method balances emissions, cost and public health concerns
A computational method improves the balance between power system operational costs, security of power supply and public exposure to pollutants.
NREL minimizes uncertainty in PV performance measurement
A new way to measure the efficiency of photovoltaic (PV) technology — the golden module — has been implemented at the U.S. Department of Energy's (DOE's) National Renewable Energy Laboratory (NREL).
Blockchain system will test this virtual power plant
The blockchain technology is used to verify and record transactions, potentially enabling consumer sharing of energy via a microgrid. The concept could help reduce load burdens on the larger energy grid.
This utility is adding 950 MW of solar and energy storage capacity
The projects will add 850 MW of battery storage and at least 100 MW of new solar generation by 2025.
Pennsylvania team wins 27th annual Future City competition
Middle schoolers from Lititz, Pennsylvania, have won the 2019 Future City competition.
Flexible membranes are key to new wave energy system
The Dielectric Elastomer Generator could generate low-cost electricity for thousands of houses.
Scania to trial autonomous electric bus service
The trials will be done in two stages, with and without passengers. The buses will have a human driver on board to monitor operations and assist passengers.
Renewables drive utility market for reciprocating engines
The equipment is especially popular in areas with high levels of electricity generation from intermittent sources such as wind and solar.
Purdue graduate designs jacket for law enforcement, military personnel working outdoors
A Purdue Polytechnic New Albany graduate has created a line of battery-powered heated jackets to protect military personnel, law enforcement and others working outside during the harsh winter months.

Hoover Dam completes a pressure-relief valve upgrade
A two-decade-long project to upgrade the Hoover Dam’s original pressure-relief valves has reached its conclusion.
Grid stabilization by use of automobile battery storage
Used automobile battery storage systems can find a second life by being pressed into service to start up energy generating assets.
Federal investigation into heating, electricity issues at Brooklyn jail
Prisoners at the jail endured the recent polar vortex, which plunged the region into sub-zero temperatures, without heat, hot water, hot food and light.
Engineers show the heart can replace batteries in medical implants
Engineers from Dartmouth College have developed a way to eliminate batteries as the power source for implantable medical devices such as pacemakers and defibrillators. The new power source is none other than the heart itself.
Video: Cardiac energy harvester designed to power pacemakers
Kinetic energy generated by the heart could be used to provide electricity for implantable medical devices like pacemakers and defibrillators.
The economics of battery-assisted hydrogen production from solar energy
Cost targets are evaluated for hydrogen production from photovoltaic power generation combined with a battery-assisted proton-exchange membrane electrolyzer.
Video: Drilling a deep hole for nuclear waste storage
Standard oil and gas drilling technology might be used to place nuke waste canisters thousands of feet underground.
New carbon capture sorbent promises efficient emission control
A new class of organic compounds captures carbon from coal-fired power plant emissions in a process that is less energy intensive than existing methods.
