The Potential of Battery Storage Solutions for Domestic and Commercial PV Installations

The developments in battery storage systems being launched to the UK market this year will help to distribute energy more efficiently, and with the PV market in a state of flux following the reductions in the tariff rates, the battery storage developments should provide some stability to the trade.

United Airlines is flying on biofuels ... here's why that's a really big deal

Chelsea Harvey for The Washington Post:   On Friday, United Airlines will launch a new initiative that uses biofuel to help power flights running between Los Angeles and San Francisco, with eventual plans to expand to all flights operating out of LAX. It's the first time an American airline will begin using renewable fuel for regular commercial operations, and the occasion is part of a bigger movement when it comes to clean transportation in the U.S. The renewable fuel used to power United's planes will be coming from a Los Angeles refinery operated by AltAir Fuels, which is using the facility to produce both renewable jet fuel and diesel fuel using a technology developed by Honeywell UOP, a major supplier and technology licenser in the petroleum industry. Back in 2013, AltAir and United announced their partnership, in which United will purchase up to 15 million gallons of biofuel over a three-year period. Friday's launch will be the first application of that agreement. The flights will use a mixture of 30 percent biofuel and 70 percent traditional fuel, and United says that the biofuel will help reduce greenhouse gas emissions by about 60 percent compared with regular fuel.   Cont'd...

GE has figured out how to make solar power batteries using greenhouse gasses

Brad Reed for BGR:  We typically think of carbon dioxide as an unhealthy byproduct of our over reliance on fossil fuels. But what if CO2 could be used to help us move away from fossil fuels and toward renewable energy sources? GE Global Research has been working with the U.S. Department of Energy to come up with a way to use excess carbon dioxide produced by power plants to store extra solar power and deliver it back to the grid for later use. There are two major components to this solar power storage system: The first component captures solar energy and keeps it stored in molten salt, while the second component takes surplus electricity from the grid to cool off carbon dioxide to the point where it becomes dry ice. To keep the solar energy stored, the molten salt will then be released into the CO2, which will act as a battery capable of deploying power when needed. The CO2-molten salt mixture will then flow through a specially designed CO2 turbine that GE says “can generate as much as 100 megawatts of ‘fast electricity’ per installed unit.” The advantage of this system is that these turbines would be able to operate at night when there’s no solar power being directly absorbed.   Cont'd...

Interview with Michael Wiener of SolarRoofHook.com

In general, the installer just removes the roof piece, locates the rafters, drills pilot holes, fastens the product to the rafter, properly seals the penetration, and grinds the tile where the mount is located before placing the roof piece back over or around the mount.

After record year, U.S. energy storage forecasted to break 1 GW capacity mark in 2019

Peter Maloney  for UtilityDive:  The U.S. energy storage market put in a strong showing in 2015 with its “best quarter and best year of all time,” according to the GTM/ESA report. And current market trends point toward continued strong growth. The recent extension of the federal Investment Tax Credit, and new guidelines under consideration at the Internal Revenue Service are expected to further boost energy storage and the pairing of storage with renewable resources. In the fourth quarter alone, the U.S. deployed 112 MW of storage capacity, representing more than the total of all storage deployments in 2013 and 2014 combined. For the full year, 221 MW (161 MWh) of storage was installed. In 2014 65 MW (86 MWh) of storage was installed in the U.S.   Cont'd...

These Lego-Like Batteries Plug In To Store Solar Power At Home

Adele Peters for Co-Exist:  Less than a year after Tesla unveiled its Powerwall battery for storing electricity at home, a startup has designed a much cheaper alternative that you can plug in yourself, without an electrician. The modular batteries, called Orison, can be hung on the wall or set on the ground to double as an LED lamp. If you want more power, you just add the units together. "Think of Orison like Legos," says co-founder and CEO Eric Clifton. "The 2.2 kilowatt-hour unit is really just one piece, so you can actually add as many as you need." The 2.2 kilowatt-hour version is as large as the company could make one unit and keep it under 40 pounds, so it could be easily shipped and moved. With one unit, if your power went out in a storm, you could keep an energy-efficient refrigerator running for about two days. If you want to back up everything in your house, you'd connect a long series of batteries together. For someone with solar panels on the roof, the batteries can store power to use at night. Right now, most people can sell extra solar power back to the grid when they're not using it, but many state laws are about to change so people will make less money. Batteries can help solar homeowners save money by making use of the power they've generated.   Cont'd...

Offshore wind projects in United States see renewed interest

By PHILIP MARCELO for AP:  The offshore wind industry has high hopes for establishing a permanent beachhead in the U.S. after years of disappointment. Business leaders and politicians who gathered for an industry conference in Boston this week said wealthy investment firms and seasoned European offshore wind companies are increasingly committing to projects along the East Coast. That, they said, is evidence a domestic industry dreamed about for nearly two decades is finally on its way. "There's a palpable sense that it's finally happening," said Bryan Martin, a managing director at D.E. Shaw & Co. That New York hedge fund is the principal backer of Deepwater Wind, a Rhode Island-based company looking to launch the country's first offshore wind farm off Block Island by the end of the year. "The U.S. tends to start small and ramp up very fast. I believe that will happen with offshore wind." Among the significant new players to emerge in the past year is DONG Energy, a Danish firm that operates more than a dozen wind farms, including some of Europe's largest.   Cont'd...

Warren Buffett Downplays His Battle With Elon Musk in Nevada Over Solar Power

Joe Carmichael for Inverse:  Buffett, in an interview with CNBC on Monday, responded to viewer questions about this clash (a clash that Bloomberg Business intensified with a cover story): two viewers asked why Buffett’s companies are preventing and deterring net metering in Nevada. Buffett responded: “We don’t have a problem with net meters, and we’re the leading in renewables in the country among regulated utilities. The [unintelligible] we do not want our million-plus customers that do not have solar to be buying solar at 10 and a half cents when we can turn it out for them at 4 and a half cents or buy it at 4 and a half cents. So, we do not want the non-solar customers, of whom there are over a million, to be subsidizing the 17,000 solar customers. Now, solar customers are subsidized through the Federal Government — as we are, with our wind and solar operations ourselves. … “In Nevada, [Musk's company, SolarCity] had an arrangement for a very limited number of people — and the public utility commission decides this — they had an arrangement where the utility had to pay way above market for solar produced by these 17,000 homes, and that —“ The interviewer interrupted to clarify: “For instance, if I have solar electricity that I’m producing, that’s more than I need, I can sell it back to you…”   Cont'd...
