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...

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?

Here's How Electric Cars Will Cause the Next Oil Crisis

Tom Randal for Bloomberg Business:  With all good technologies, there comes a time when buying the alternative no longer makes sense. Think smartphones in the past decade, color TVs in the 1970s, or even gasoline cars in the early 20th century. Predicting the timing of these shifts is difficult, but when it happens, the whole world changes.

It’s looking like the 2020s will be the decade of the electric car.

Battery prices fell 35 percent last year and are on a trajectory to make unsubsidized electric vehicles as affordable as their gasoline counterparts in the next six years, according to a new analysis of the electric-vehicle market by Bloomberg New Energy Finance (BNEF). That will be the start of a real mass-market liftoff for electric cars.

By 2040, long-range electric cars will cost less than $22,000 (in today’s dollars), according to the projections. Thirty-five percent of new cars worldwide will have a plug.  Cont'd...

Energy-Storage Startup LightSail Plots Long-Term Game Plan

Barbara Haislip for the Wall Street Journal:  Few industries are more daunting for entrepreneurs these days than clean energy.

Developing the technology and hardware is expensive, and setbacks are common. Even if all goes well, getting a product to market can take a decade or more. Most venture-fund investors, meanwhile, want a quicker payout.

Danielle Fong, co-founder and chief scientist of LightSail Energy, is trying to keep investors happy while working toward some ambitious clean-energy goals. Her company’s aim, she says, “is to produce the world’s cleanest and most economical energy-storage system” through a technology that uses compressed air to store energy from the grid. LightSail’s technology will do this more efficiently than other solutions, Ms. Fong says, by capturing some of the excess heat that comes when compressing air.  “Until now, this was wasted, reducing efficiency,” she says.

Founded in 2009, Berkeley, Calif.-based LightSail has raised $70 million from several investors, including Bill Gates, Peter Thiel,Khosla Ventures and the French energy giant Total.  Cont'd...

Apple leftovers key for future energy storage

By Tereza Pultarova for E&T:  German researchers have developed a new carbon-based active material that can be manufactured from apple leftovers and used to build better energy storage systems.

The apple-based material can be used as the negative electrode in sodium-ion batteries, which are currently being researched as a more environmentally friendly and cheaper alternative to lithium-ion batteries.

Instead of energy-intensive lithium mining, which frequently damages the environment, battery manufacturers in future could be using organic waste to make batteries.

In tests, the new material discovered by researchers from the Helmholtz Institute Ulm of Karlsruhe Institute of Technology, has demonstrated ‘excellent electrochemical properties’, allowing the researchers to carry out 1000 charge and discharge cycles during which the apple-based battery demonstrated high stability as well as capacity.  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...

Coalition of US states pledge to accelerate renewable energy efforts

Oliver Milman for The Guardian:  A bipartisan group of governors from 17 states has pledged to accelerate their efforts to create a green economy in the US by boosting renewables, building better electricity grids and cutting emissions from transport.

An accord signed by the governors states that the US must “embrace a bold vision of the nation’s energy future” by reducing emissions, transitioning to clean energy sources and ensuring that infrastructure isn’t risked by extreme weather events such as floods and wildfires.

The agreement sets out commitments to expand renewable energy and energy efficiency and integrate solar and wind generation into electricity grids. These grids will be “modernized”, the accord states, to improve energy reliability.  Cont'd...

Low-cost energy storage for power grid can be found in your Water Heater

By David Shaffer  for Star Tribune:  The least-expensive battery to store energy from the electric power grid may be sitting in homeowners’ basements — the electric water heater.

That is the surprising finding of research released Wednesday by the cooperative power industry, including Maple Grove-based Great River Energy, and an environmental group.

Customers at many utilities already save money by heating water at night, taking advantage of low, off-peak electric rates. It requires a special electric water heater that holds a day’s worth of household water, but offers long-term savings.

Now, a study by the Brattle Group, an economic consulting firm, says that the nation’s 50 million residential electric water heaters can address bigger challenges on the power grid, such as storing intermittent renewable energy from wind farms and solar arrays.  Cont'd...

The Koch Brothers' Dirty War on Solar Power

Tim Dickinson for Rolling Stone:  The full political might of Florida's IOUs was on display in December, when a deceptive campaign, funded by the state's electric utilities, crushed a citizen-led effort to open Florida to solar competition through the 2016 ballot. "When your opponents have no ethical foundation, have unlimited resources and are willing to say and do anything to defeat you," says Stephen Smith, director of the Southern Alliance for Clean Energy, which led the pro-solar effort, "it's a tough hurdle to overcome."

It should come as no surprise that the utilities have fought so hard. The rise of cheap, distributed solar power poses a disruptive – and perhaps existential – threat to the traditional electric utility business.

Monopoly electric utilities used to make sense. Dirty power, generated at a distance from population centers, was carried over a set of transmission lines to homes and businesses. Consumers got reliable power from a single provider. IOUs were guaranteed a profit – both for building power plants and transmission lines as well as for the electricity itself.  Full Article:

Boeing delivers fuel cell energy storage system to U.S. Navy

Ryan Maass for UPI:  Boeing has delivered its reversible solid oxide fuel cell, for generating clean electricity, to the U.S. Navy for testing.

The fuel cell system is designed to generate, compress and store hydrogen from renewable sources such as wind and solar to produce zero-emissions electricity.Boeing's delivery to the Navy follows 16 months of development.

The technology is capable of both producing and storing energy. The first unit was commissioned on the Southern California power grid prior to its installation on the Navy's 'microgrid' for further testing.

"This fuel cell solution is an exciting new technology providing our customers with a flexible, affordable and environmentally progressive option for energy storage and power generation," Boeing Advanced Technology Programs director Lance Towers said.

Boeing officials say they were able to develop the fuel cell using their experience with the energy systems used for their unmanned undersea vehicles.  Cont'd...

MIT Tool Gives the Cost of Installing Solar Panels on Any Roof in Your City

Daniel Oberhaus for Motherboard:  The world, it seems, is falling in love with solar energy. Recent years have seen the increasing adoption of solar power around the world as an alternative energy source for everything from individual homes to the entire energy grid, with the United States’solar capacity having grown to 24 GW, a more than a 17-fold increase since 2008. Part of this rapid growth for solar infrastructure is the result of markedly more efficient solar energy cells, but in spite of these recent technological advances, transitioning to solar power still doesn’t make sense (at least economically speaking) everywhere.

Installing photovoltaic systems can be pretty pricey, and home- and business-owners have to engage in a complex cost-benefit analysis to see if transitioning to solar power is an economically sound idea. The “pain-in-the-ass” factor of such calculations alone might be enough to turn people off of the idea of contemplating installing a photovoltaic system, so the folks at MIT came up with a solution: Mapdwell.

Mapdwell maps the solar potential of entire cities by doing a cost-benefit analysis for every rooftop to determine if installing solar panels on that rooftop is worth the investment. All you do is enter your address into the program, and it will tell you the expected installation costs, the number of years it will take to earn back this investment from your photovoltaic system, the amount of carbon offset by the installation, as well as incredibly detailed installment specs such as the optimal panel tilt and the number of panels that could fit on the roof.  Cont'd...

This year will be a solar-powered Super Bowl

By Jeff Clabaugh for WTOP:  Levi’s Stadium in Santa Clara, California, will set the stage for Sunday’s Super Bowl, and it will be a solar-powered event.

Levi’s Stadium, which opened in July 2014, is the first professional football stadium in the NFL to open with LEED Gold certification, according to the Solar Energy Industries Association in Washington.

Princeton, New Jersey-based NGR Solar LLC installed more than 1,150 solar panels at the stadium during its construction — enough to produce 375 kilowatts of peak power. The system can generate enough power in a year to meet electricity demand during every San Francisco 49ers home game.

The solar panels cover three bridges that connect the stadium to the main parking lot and the “NRG Solar Terrace” that overlooks the field.

There are 544 solar panels on the stadium roof and another 642 on the bridges, which also serve as canopies covering the bridges.  Cont'd...
