GTM: 10 US states have energy storage pipelines greater than 100MW

Danielle Ola for Energy Storage News: According to the latest GTM Research figures, energy storage is coming into its own and is no longer confined to a handful of US states. 21 states now have 20MW of storage projects proposed, in construction or deployed. Further, 10 states have pipelines of more than 100MW.

Stabilizing battery storage

Morgan Sherburne for U of Michigan News:  An issue that has long plagued renewable energy facilities is how to efficiently store energy collected from sun or wind.

Now, University of Michigan and University of Utah chemists have developed an energy-storing molecule that is 1,000 times more stable than current compounds, potentially leading to a longer-lived, more efficient battery.

The researchers are working to develop industrial-scale batteries that can store large amounts of energy for deployment when the sun sets or the wind stops blowing.

Deep-cycle lead batteries or lithium ion batteries are already on the market, but each type presents challenges, including the significant environmental hazards of disposal. Also, these kinds of batteries wear out relatively quickly.  Cont'd...

Mercom: Project funding for energy storage totalled US$820 million in 2016

Andy Colthorpe for Energy Storage News:  Project funding for energy storage jumped to US$820 million in 2016 from just US$30 million in 2015, while Sonnen was revealed as the energy storage company to raise the most VC funding this year.

The latest quarterly report from Mercom Capital on financial activity in battery storage, smart grid and energy efficiency wraps up the results for the entirety of 2016. It found that during the year, energy storage companies raised US$820 million in project funding across seven deals, compared to US$30 million across three deals in 2015.

The majority of this project funding, US$625 million, was raised in the third quarter of the year and included Tabuchi America netting US$300 million for residential work and Advanced Microgrid Solutions with US$200 million of project financing from Macquarie Capital.  Cont'd...

Batteries Need to Get Big-Like, Enormous-for Solar Power to Shine

Vaclav Smil for IEEE Spectrum:  It would be a lot easier to expand our use of solar and wind energy if we had better ways to store the large quantities of electricity we’d need to cover gaps in the flow of that energy.

Even in sunny Los Angeles, a typical house roofed with enough photovoltaic panels to meet its average needs would still face daily shortfalls of up to about 80 percent of the demand in January and daily surpluses of up to 65 percent in May. You can take such a house off the grid only by installing a voluminous and expensive assembly of lithium-ion batteries. But even a small national grid—one handling 10 to 30 gigawatts—could rely entirely on intermittent sources only if it had gigawatt-scale storage capable of working for many hours.

Since 2007, more than half of humanity has lived in urban areas, and by 2050 more than 6.3 billion people will live [PDF] in cities, accounting for two-thirds of the global population, with a rising share in megacities of more than 10 million people.  Cont'd...

Glow-in-the-dark dye could fuel liquid-based batteries

Charlotte Hsu for University of Buffalo:  BUFFALO, N.Y. — Could a glow-in-the-dark dye be the next advancement in energy storage technology?  Scientists at the University at Buffalo think so.

They have identified a fluorescent dye called BODIPY as an ideal material for stockpiling energy in rechargeable, liquid-based batteries that could one day power cars and homes.  BODIPY — short for boron-dipyrromethene — shines brightly in the dark under a black light.

But the traits that facilitate energy storage are less visible. According to new research, the dye has unusual chemical properties that enable it to excel at two key tasks: storing electrons and participating in electron transfer. Batteries must perform these functions to save and deliver energy, and BODIPY is very good at them.  In experiments, a BODIPY-based test battery operated efficiently and with longevity, running well after researchers drained and recharged it 100 times.  Cont'd...

DOE energy innovation hub backs two key future battery technologies

Nick Flaherty for EE Times:  After four years of evaluation, the Joint Center for Energy Storage Research (Chicago, IL) is backing two key technologies for the future of battery systems.

The Center was set up four years ago with a five year remit to explore new battery technology for transportation and the electricity grid that, when scaled to commercial production, are capable of delivering five times the energy density at one-fifth the cost of commercial batteries available in 2011.

The Center has investigated 1,500 compounds for electrodes and 21,000 organic molecules relevant for liquid electrolytes as well as filing 52 invention disclosures and 27 patent applications, says director George Crabtree. Five techno-economic models created by JCESR for designing virtual batteries on the computer are being used to evaluate the best pathways for beyond-lithium-ion systems to reach 400 watt hours per kilogram (400 Wh/kg) and $100 per kilowatt hour ($100/kWh).  Cont'd...

Repurposing Electric Vehicle Batteries

EV batteries still have storage capacity, typically at 80 percent, after they're removed from their vehicles and can be reclaimed for a "second life" as stationary power sources.

The Aquion Energy Saltwater Storage Battery

This system is working good in a 4000 sq ft shop & house combo, but could use more storage for peace of mind & will likely upgrade next year.

The Future of Bio-Inspired Batteries

A major advantage that bio-inspired batteries have as compared to other batteries is their ability to allow an instant recharge.

Batteries Get a Boost From California Utilities

If we stop and take a critical look at the fragility of our energy supply system, we see that it could be strengthened by distributing energy generation and storage. This means it's not just the utility company's job to store energy… it's everyone's job.

'Ideal' energy storage material for electric vehicles developed

Walt Mills for Phys.org:  The energy-storage goal of a polymer dielectric material with high energy density, high power density and excellent charge-discharge efficiency for electric and hybrid vehicle use has been achieved by a team of Penn State materials scientists. The key is a unique three-dimensional sandwich-like structure that protects the dense electric field in the polymer/ceramic composite from dielectric breakdown. Their results are published today (Aug. 22) in the Proceedings of the National Academy of Sciences (PNAS).

"Polymers are ideal for energy storage for transportation due to their light weight, scalability and high dielectric strength," says Qing Wang, professor of materials science and engineering and the team leader. "However, the existing commercial polymer used in hybrid and electric vehicles, called BOPP, cannot stand up to the high operating temperatures without considerable additional cooling equipment. This adds to the weight and expense of the vehicles."  Cont'd...
