GE at ‘very early stages’ of developing Mexico’s first energy storage systems

on September 14, 2017

Energy Storage NewsGeneral Electric (GE) is developing Mexico’s first ever grid-scale energy storage projects to aid with the integration of wind and solar into electricity networks.

The US multinational was reported by Mexican financial newspaper El Financiero to be developing five such systems, which the paper said was part of an increased investment in renewables. El Financiero said that according to GE Grid Solutions Latin America’s leader of digital solutions, Rodrigo Salim, each system would likely cost at least US$5 million to develop and deploy.

Salim said energy storage could help deliver power resiliency and quality in an age of renewables on the grid, the report stated. GE Grid Solutions is a joint venture (JV) between GE and power engineering company Alstom.

A representative of GE Power responded to an enquiry from Energy-Storage.News asking for more details on the reported Mexico projects. She said that while GE was able to confirm the reports, there were currently no further details available to press.

The representative said the projects “are in the very early stages” and that there was no further information she could give beyond the contents of the El Financiero report.

Lithium-ion energy storage: Key component of America’s renewable energy future

on September 14, 2017

the washington timesOne of the more interesting storylines in conjunction with the recent total solar eclipse in the United States was how it might affect power plants that rely on the sun to produce electricity.

Many in the energy industry wondered how the power grid would function when the sun went dark in the middle of the day, since solar contributes nearly 42,000 megawatts, or 5 percent, of peak electricity demand. How would utilities manage the relatively rapid down-ramping, followed by an equally rapid up-ramp of power flowing from solar plants?

Fortunately, both the grid and the plants powering it proved remarkably resilient to the energy and demand fluctuations.

But as the U.S. shifts away from traditional fuels and relies more heavily on renewables like wind and solar for power generation, the question becomes even more important. How will we keep the lights on and air conditioning running and our phones and electric vehicles charged when the sun goes down or the wind stops blowing?

This is where reliable and efficient advanced energy storage will play an increasingly crucial role in grid stability in the years to come. According to the U.S. Energy Information Administration, approximately 10 percent of total U.S. energy consumption and 15 percent of electricity generation came from renewable sources in 2016. The U.S. Department of Energy has set a goal of 30 percent of U.S. electric generation to come from renewables by 2025. Solar and wind power will make up the lion’s share of that new renewable generation capacity.

While natural gas, coal and nuclear power will continue to provide a significant portion of our baseload power for some time to come, intermittent energy sources play a role too — and this role is expected to increase. If we’re truly to make renewables an economically viable, baseload option, we must have ways to store large amounts of power for use when renewables can’t meet the demand.

Minnesota conference explores how the Midwest can expand energy storage

on September 14, 2017

Midwest-Energy-NewsWhile states like California and Hawaii lead the growing market for energy storage, the potential in the Midwest is growing.

Minnesota is seeing a small but growing number of lithium ion battery storage projects that will be discussed along with other battery-related topics at the Midwest Energy Storage Summit in Minneapolis Sept. 15.

Sponsored by the the Energy Transition Lab at the University of Minnesota, the event features speakers such as Mary Powell, CEO and president of Green Mountain Power; Christopher Clark, president of Xcel Energy for Minnesota and the Dakotas; George Crabtree of Argonne National Laboratory and Kelly Speakes-Backman, CEO of the Energy Storage Association.

The transition lab’s initial conference, two years ago, was the first time in Minnesota experts and industry officials came together to discuss storage, according to Barbara Jacobs, energy storage project manager. One result of the conference was the creation of the Minnesota Energy Storage Alliance to share knowledge and promote battery storage.

“There seems to be a lot of interest and excitement about storage across the board right now,” Jacobs said.

So what’s the difference between storage between now and two years ago? One is clearly dropping prices and increased production of lithium ion batteries, accompanied by products from Tesla, Panasonic, LG and many others.

Secondly, utilities are taking greater interest, with 80 percent nationwide considering storage projects, according to a recent survey.

Minnesota utilities are stepping up with projects and proposals. Xcel Energy proposed a solar storage battery project that regulators failed to approve while allowing the utility another chance to submit it after making changes.

Utilities see benefits in energy storage, even without mandates

on September 14, 2017

energy storage utility diveThe fact that California’s three investor-owned utilities were at the top of the Smart Electric Power Alliance’s recent rankings is not surprising, but the presence of utilities in Indiana and Ohio is notable.

California has been a leader in energy storage, with a 2010 law that requires the state’s IOUs to procure 1.3 GW of storage capacity by 2020 and then a 2016 law requiring each IOU to procure another 166 MW of storage.

There has been no similar legislative push in either Indiana or Ohio and yet Indianapolis Power & Light and Duke Energy Ohio were third and fifth, respectively, in SEPA’s rankings of utilities that connected the most energy storage to their systems in 2016. IPL installed 20 MW in 2016, and 16 MW were connected to Duke Energy Ohio last year.

The rankings do not tally how much energy storage a utility built or owns, but how much was connected to their system. So while IPL built and owns the storage facility in its territory, Duke does not own the 16 MW of storage that connected to its system in 2016. Similarly, while California’s utilities are permitted to own some energy storage assets, they do not necessarily own all the storage facilities connected to their systems.

Measured by energy (MWh), IPL ranked fourth with 20 MWh, and Duke Energy Ohio ranked eighth with 6.1 MWh.

Ranked by energy storage watts per customer, IPL and Duke actually beat the California utilities, ranking fifth and sixth with 42 W/customer and 23 W/customer, respectively.

Go Electric to provide energy storage system for Ft. Custer microgrid

on September 13, 2017

Go Electric won a $499,506 contract by Electricore for a demonstration microgrid project at the Fort Custer Training Center in Michigan.

The project is funded by the Environmental Security Technology Certification Program (ESTCP), a Department of Defense program for promoting the transfer of proven innovative technologies into field use.

Go Electric will deliver a 400 kW/160 kWh battery energy storage system and will provide engineering support for the installation and commissioning of the energy storage system into a facility-wide microgrid. Go Electric will also support the integration of a microgrid controller provided by power management company Eaton.

Electricore, a non-profit consortium formed at the request of the Department of Defense to implement advanced energy, transportation and electronics technologies, is leading the project with support from Eaton and local utility Consumers Energy. The Michigan Army National Guard, which uses Fort Custer alongside several other units, is hosting the project.

The microgrid will enhance power surety, energy resilience, distributed generation management and demand response, while contributing to the critical power needs of nearby military installations. In addition to the 400 kW system, the microgrid includes 1.375 MW of legacy diesel generators and 720 kW of photovoltaics.

BYD Announces 1st Installation Of Its B-Box HV Home Energy Storage Unit

on September 13, 2017

energy storage cleantechnicaAt Solar Power International (SPI) in Las Vegas this week, BYD announced the world’s first installation of its high-voltage B-Box energy storage system in Germany.

BYD’s B-Box is a modular energy storage system that allows customers to add battery modules to the B-Box unit as demands increase over time. This particular installation in Germany utilized 9 battery modules for a combined storage capacity of 11.5 kWh. If greater capacity is required, up to 5 B-Box systems can be connected in parallel.

BYD developed the B-Box to store energy generated from rooftop residential solar systems, which it can then meter back out to the house after the sun has set. It is intelligent enough to minimize the amount of solar energy sent to the grid or intelligently feeding in battery power to offset home usage that would have pushed the household into a higher tier of electricity usage, depending on the rate and fee structure of the local utility.

The BYD B-Box is available in Europe and Australia today, with a US launch expected later this year in Hawaii as well as select west and east coast markets with high electricity prices that make the B-Box a more lucrative financial proposition. The B-Box has evolved over the last few product offerings and is now a modular, stable, high-voltage unit that makes use of BYD’s long-lasting Lithium Ferro Phosphate (LiFePo4) batteries. These batteries have a slightly lower energy density than most EV batteries, resulting in a slightly larger size and weight per kWh (resulting in a slightly heavier product), but they are well suited for home energy storage since they reportedly have a much longer lifespan and far lower deterioration over their lifetimes.

EV Energy Storage Breakthrough Gets $1 Million To Cross The Valley Of Death

on September 12, 2017

energy storage cleantechnicaThe US Energy Department has been steaming full speed ahead on cutting edge energy storage technology, and the latest development is one of those environmental twofers we love. A $1 million grant from the agency will help a company called Saratoga Energy to bridge the gap between its labwork and a low cost, high efficiency energy storage technology ideal for electric vehicles — without the carbon footprint, too.

The Union of Concerned Scientists took a look at the lifecycle carbon footprint of EVsand determined that it is significantly smaller than conventional gas-powered vehicles.

However, EVs still have a carbon footprint, and in the interests of global carbon management that footprint needs to be as small as possible.

Part of the EV carbon problem is the graphite used in lithium-ion energy storage technology.

Graphite is a form of pure carbon chemically identical to diamonds but with different structural characteristics.

The carbon footprint of mining and processing comes into play for naturally occurring graphite, and the go-to source for synthetic graphite is petroleum coke (surprise!).

Local environmental issues also bedevil the graphite industry, but that’s a whole ‘nother can of worms.

The Saratoga Energy solution is to skip the graphite supply chain middleman and go straight to the source: carbon.

MIT turns to millennia-old tech for renewable energy storage

on September 12, 2017

CurbedWith renewable energy sources becoming more and more advanced, storing that energy means big business. While we’ve seen technological breakthroughs enabling everything from DIY powerpacks to batteries integrated into windmills, one team from the Massachusetts Institute of Technology (MIT) is looking to old-school innovations for next-generation energy storage techniques. How old school? Over three millennia.

Indeed, MIT researchers have reinvented firebricks, a Bronze-Age technology created by the Hittites—who occupied what is today Turkey, in the 17th century BC. Firebricks were designed by the Hittites to retain heat for long periods of time, if properly insulated.

Such a device would be immensely useful today, according to the MIT team, citing a high demand for industrial heat. The team’s Firebrick Resistance-heated Energy Storage (FIRES) system stores thermal energy (heat) in firebricks and later converts the energy back into electricity. Oh, and storing this energy costs 1/40th the price of putting it into batteries.

This solution could be a game-changer for the renewable energy industry, which has always suffered from the problem of over-producing on some days when the wind or sun are strong and under-producing on others.

“I believe FIRES is an innovative approach to solve a real power grid problem,” said Regis Matzie, an electric expert not affiliated with the research told Global Construction Review

HomeMore Energy Storage Industry NewsReport: 31 Utilities Added Energy Storage for The First Time in 2016 Report: 31 Utilities Added Energy Storage for The First Time in 2016

on September 12, 2017

power engineeringA new report by the Smart Electric Power Alliance indicated 31 utilities, or 43 percent of the utilities surveyed for the study, added energy storage to the grid in the last year.

All told, 207 MW of energy storage was deployed last year in 829 systems. Utilities have now installed a total of 622 MW of energy storage in total.

As expected, California had the most energy storage established in 2016 at 120.5 MW, much of which was rapidly deployed in response to the Aliso Canyon natural gas storage leak. Indiana was the second at 22 MW, with Ohio at 16.1 MW.

Of the total added, 151 MW was used for utility supply. Non-residential accounted for 54 MW, with residential at 4.5 MW.

Energy storage is set to grow further, as the cost of battery-based storage has dropped more than 60 percent since 2012. Additionally, the Federal Energy Regulatory Commission has issued a notice of proposed rulemaking that would remove barriers to energy storage participation in wholesale markets.
