Secretary of Energy Rick Perry Announces $68.5 Million for Advanced Vehicle Technologies Research




WASHINGTON, D.C. - Today (May 1), U.S. Secretary of Energy Rick Perry announced up to $68.5 million in available funding for early-stage research of advanced vehicle technologies that will enable more affordable mobility, strengthen domestic energy security, and enhance U.S. economic growth.

“Transportation is fundamental to the American way of life,” said Secretary Perry. “Investing in early-stage research of advanced transportation technologies can give families and businesses greater choice in how they meet their mobility needs while reducing energy costs and making our transportation more efficient and reliable.”

Funded through the Department of Energy’s (DOE’s) Office of Energy Efficiency and Renewable Energy, projects selected through this Vehicle Technologies Office funding opportunity will address priorities in advanced batteries and electrification, including cyber security related to electric vehicle charging; materials for both lighter weight vehicle structures and advanced powertrains; technology integration and energy-efficient mobility systems; and engines and fuels, including technologies for off-road applications as well as the co-optimization of engines and fuels.

What are flotovoltaics? It's floating solar and an emerging application where solar panels are designed and installed to float on bodies of water.

Localities in the United States are showing an increasing interest in installing this innovative solar technology and our technical experts at NREL have received numerous requests for analytical support as this new exciting new application for solar power begins to reveal its potential.

Aging Wind Farms Are Repowering with Longer Blades, More Efficient Turbines

Old wind farms that have towered over the same fields for more than a decade may be generating more power now than ever before.

As America's biggest wind farms age, their owners are starting to "repower" them with more efficient turbines, new electronics and longer, lighter blades that can sweep more wind with each rotation. The result is a thriving new industry, new jobs and more renewable energy.

What makes a wind turbine break? NREL's drivetrain experts want to know.

One way to reduce the cost of #wind energy is to understand how to keep a wind turbine operating smoothly. Check out how researchers at the National Renewable Energy Laboratory are investigating the likely causes of premature drivetrain failure.

Distributed Solar PV for Electricity System Resiliency


Distributed solar systems have the potential to supply electricity during grid outages resulting from extreme weather or other emergency situations. As such, distributed solar can significantly increase the resiliency of the electricity system.

In order to take advantage of this capability, however, the systems must be designed with resiliency in mind and combined with other technologies, such as energy storage and auxiliary generation.

A new paper from NREL presents the basics of designing distributed solar systems for resiliency - including the use of energy storage, hybrid fuel-use and microgrids - and provides policy and regulatory considerations for encouraging the use of these distributed system designs.

When Does Energy Storage Make Sense? It Depends.

An example electric usage profile with demand billing and TOU rates.  The high TOU rates are from 7 am to 8:30 pm.  Demand "peaks" at 1 pm.
February 25, 2018 by Lars Lisell

“It depends” is an engineer’s favorite response to just about every question.  But “it depends” is an appropriate response when evaluating whether installing an energy storage system is a good idea. Energy storage can be confusing. The technology adds value to electrical systems by charging when there is excess energy on the system, storing the power until it is required, then discharging when the energy system requires additional energy. Unlike traditional generators that turn fuel into electricity, an energy storage system is used to move energy around.  A few common applications for energy storage include moving energy use from a period of high consumption to a period of low consumption, storing renewable generation to be used at night, or storing grid power to be used during periods of grid outage.  For an energy storage system to make economic sense, the value of providing this service to a facility or the electrical system must exceed the cost of the energy storage system.  How can a consumer determine if an energy storage system makes sense for a facility?  The answer often lies in the utility bill.[1]

A Powerful Mix of Solar and Batteries Is Beating Natural Gas

Updated on
From Climate Changed
 
Natural gas is getting edged out of power markets across the U.S. by two energy sources that, together, are proving to be an unbeatable mix: solar and batteries.

In just the latest example, First Solar Inc. won a power contract to supply Arizona’s biggest utility when electricity demand on its system typically peaks, between 3 p.m. and 8 p.m. The panel maker beat out bids from even power plants burning cheap gas by proposing to build a 65-megawatt solar farm that will, in turn, feed a 50-megawatt battery system.

It’s a powerful combination for meeting peak demand because of when the sun shines. Here’s how it’ll work: The panels will generate solar power when the sun’s out to charge the batteries. The utility will draw on those batteries as the sun starts to set and demand starts to rise.

Through ‘Virtual Power Plant,’ 50,000 Aussie Households To Get Solar, Tesla Battery Systems

 


Posted by Betsy Lillian February 5, 2018


 

South Australia’s state government has announced a plan to build what it calls the world’s largest “virtual power plant,” a network of at least 50,000 residential solar and battery systems.

Beginning with a trial of 1,100 Housing Trust properties, the program will install – at no charge – a 5 kW solar system and 13.5 kWh Tesla Powerwall 2 battery.
