Obama administration opens up Long Island to offshore wind development

SCOTT WALDMAN for Politico :  The federal government has designated an 81,000-acre area off of Long Island for possible commercial offshore wind development. The move by the federal Bureau of Ocean Energy Management on Wednesday to open the federal waters 11 miles off of New York to major wind development projects will be a significant boost to the Cuomo administration’s aggressive climate policies. The Bureau of Ocean Energy Management will now conduct an environmental assessment, with a possible sale of leases to follow. “New York has tremendous offshore wind potential, and today's milestone marks another important step in the President's strategy to tap clean, renewable energy from the Nation’s vast wind and solar resources,” U.S. Secretary of the Interior Sally Jewell said in a statement. “We will continue to work with the State and local stakeholders through a collaborative effort as we determine what places have the highest potential and lowest conflict to harness the enormous wind energy potential off the Atlantic seaboard.”   Cont'd...

The world's first solar airport no longer pays for electricity

Jethro Mullen for CNN:  Fed up with their hefty electricity bill, managers at Cochin International Airport in southern India took matters into their own hands. Three years ago, they began adding solar panels -- first on the roof of the arrivals terminal, then on and around an aircraft hangar. The success of those initial efforts led to a much bigger endeavor. "We wanted to be independent of the electricity utility grid," Jose Thomas, the airport's general manager, told CNNMoney. Last year, the airport commissioned the German company Bosch to build a vast 45-acre solar plant on unused land near the international cargo terminal. The plant came online in August, making Cochin the world's first fully solar-powered airport. The tens of thousands of panels generate on average slightly more than the roughly 48,000-50,000 kilowatts of power that the airport -- the seventh busiest in India -- uses per day, according to Thomas. Surplus energy is fed into the wider electricity grid. The big project cost around 620 million rupees ($9.3 million), a sum the airport expects to save in less than six years by not having to pay electricity bills anymore. It also estimates the solar plant will avoid more than 300,000 metric tons of carbon emissions from coal power over the next 25 years.   Cont'd...

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

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.

Solar Thermal Fluid Sampling: Personal Safety and System Design Considerations

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...

Solar Thermal Fluids - Why It Is So Important To Choose The Right Fluid

The most popular fluid used in CSP plants is the eutectic mixture of BDO. This fluid has a high operating temperature (up to 400 degrees Celsius), a low viscosity and good thermal stability.

Is the US undermining India's solar power programme?

Justin Rowlatt for BBC News:  Whatever happened to all the talk of international co-operation to tackle climate change that we heard during the climate conference in Paris just a few months ago? That is what many environmentalists are asking after the United States delivered a damaging blow to India's ambitious solar power programme this week. In response to a US complaint, a World Trade Organization (WTO) panel has ruled that India's National Solar Mission breaches trade rules. It judged that India's policies on buying locally made solar power equipment discriminates against imports. "The ink is barely dry on the UN Paris Climate Agreement, but clearly trade still trumps real action on climate change," Sam Cossar-Gilbert of Friends of the Earth International said in a statement. But is the decision really as damaging as many commentators seem to think? Let's start at the beginning.   Cont'd...

The oil industry has invented an ironic new use for solar power

Cassie Werber for Quartz:  There’s a huge project taking shape in the deserts of Oman. It will extract crude oil from the ground by pumping vast quantities of steam into it. To produce the steam, water will be brought to a boil using as much as a gigawatt of energy. The source of that energy: the sun. Using solar power to get fossil fuels out of the ground will strike some as ironic—especially since, if that method weren’t available, the high cost of extracting the oil might lead to more pressure to use cleaner energy sources, such as solar, instead. But GlassPoint, the American company behind the new technology, says that the project and others like it will help fossil-fuel drillers limit carbon emissions. The process of “enhanced oil recovery,” where steam is used to loosen thick oil and make it easier to pump, usually involves burning natural gas to heat water. GlassPoint says its technology can cut that gas consumption, and the consequent carbon emissions, by   up to 80%.   Cont'd...
