Panasonic Commits To Solar Cell Production With Tesla At New York Plant

Alan Ohnsman for Forbes:  Panasonic will make solar cells with Tesla at a factory under construction in Buffalo, New York, broadening a partnership between the electric-car maker and Japanese electronics giant that goes back nearly a decade. The companies said in a joint statement today that they finalized plans to produce high-efficiency photovoltaic cells at the plant, with initial production scheduled for the second half of 2017. Output of the energy modules, for use in solar panels, Tesla’s planned solar roofs and to charge up Tesla’s Powerwall and Powerpack battery storage units, is to reach 1 gigawatt by 2019, the companies said.

Instead Of Trump's Wall, Let's Build A Border Of Solar Panels

Homero Aridjis & James Ramey for Huffington Post:  President-elect Donald Trump has repeatedly called for Mexico to build a wall between our countries. There is indeed a way that Mexico could create a barrier between the U.S. and Mexico, one constructed exclusively on the Mexican side, with substantial benefits for both countries and the planet: a solar border. Sunlight in the northern deserts of Mexico is more intense than in the U.S. Southwest because of the lower latitude and more favorable cloud patterns. And construction and maintenance costs for solar plants in Mexico are substantially lower. Thus, building a long series of such plants all along the Mexican side of the border could power cities on both sides faster and more cheaply than similar arrays built north of the border.   Solar energy is already being generated at lower prices than those of coal. With solar plants along vast stretches of the almost 2,000-mile U.S.-Mexico border on the Mexican side, a new high-voltage direct-current (HVDC) grid could be set up to transmit energy efficiently from that long, snaking array to population centers along the border. HVDC power lines lose exponentially less energy over long distances than traditional power lines.   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...

Energy Storage Market and Trends

Adding backup power provides a tremendous value to the customers in certain areas with unreliable grid. In combination with other values, this is a trend that is producing a very strong demand - stronger than we initially thought.

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...

Offshore wind energy system combines sea water and wind to create electricity

Megan Treacy for TreeHugger:  We've seen our share of interesting wind power designs, but often the technology can't come anywhere close to matching what the traditional horizontal axis wind turbines can do. There's a reason that when we think of wind energy, we think of giant masts with rotating blades and it's because that design is incredibly effective -- just look at Scotland and other areas around the world that now get a majority of their electricity needs from wind power. The design isn't without its flaws; those rotating blades do pose a hazard to birds and bats and the cost of manufacturing and installing all of those giant parts can be expensive. When it comes to offshore wind power in the U.S., that has been a major roadblock. The energy generation potential is huge, but so is the cost. An energy start-up company called Accio Energy -- yes, a Harry Potter reference -- thinks it has a solution to that problem, one that will generate as much if not more energy from offshore wind than a traditional wind turbine, but at half the cost. There are no moving parts, instead Accio's technology consists of large permeable panels on masts that let the ocean winds blow right through.   Cont'd...

Could depleted oil wells be the next step in energy storage?

Power-Technology.com - Quidnet Energy is hoping to revolutionise energy storage with its underground pumped hydro concept, which uses abandoned oil and gas wells to store and release pressurised water, driving turbines and feeding electricity back into the grid. How does the concept work and how far could it go? Quidnet co-founder Aaron Mandell explains. As the cost of renewable energy continues to decline and intermittent clean power sources such as wind and solar gain ever an ever larger foothold in the global energy mix, the ability to store energy that can be quickly dispatched when needed has become as important as the development of renewables themselves. Robust storage options could allow for greater integration of intermittent renewables, as they facilitate flexible capacity-building that relies far less on coal and gas-fired plants for baseload generation, meaning energy storage is a key step in the journey to wean the world off its fossil fuel addiction.   Full Interview:
