Greensmith Energy, a Wärtsilä Company, and American Electric Power (AEP) have agreed to install a 4 MW energy storage system integrated with the Buck and Byllesby hydroelectric power plants in southwest Virginia, USA. The integration of advanced energy storage and software with hydroelectric generation is seen to be a world’s first hybridized system of its kind to provide ancillary services.

The system, due to begin operating in the first quarter of 2018, will deliver PJM frequency regulation market (PJM=Pennsylvania, Jersey, Maryland power pool) one of the first new energy storage systems since the adoption of new frequency regulation signals and requirements for regulation service. Harnessing Greensmith’s GEMS software platform that offers multiple storage applications, the project will serve both of PJM’s frequency regulation markets, including traditional regulation known as RegA and dynamic regulation known as RegD.

“The advent and growth of hybridized power, enabled by the integration of intelligent energy storage, has always been a key part of our technology vision,” said Greensmith CEO John Jung. “Although we’ve delivered six grid-scale energy storage systems to the PJM market, this innovative hybrid project will see AEP raise the standard for hydroelectric use-cases globally. And the potential for hybridization is massive as hydroelectricity represents over 1,000 gigawatts of generation globally, roughly a sixth of the world’s total.”

The new batteries are more efficient and powerful than lithium ion, as well as being safer and more environmentally friendly to manufacture. They are based on the ultra-capacitor principle and feature vertically aligned carbon nanotube electrodes. These have a unique coating which enables the batteries to provide five times the power density than existing ultra-capacitors.

The batteries can be charged and discharged in seconds and can do so over a million cycles without any loss in performance, far in advance of conventional lithium-ion batteries which take minutes, sometimes hours, to fully charge and typically have 5,000 cycle limits.

NAWA Technologies, based in the South of France, has also pioneered a specialised nano-manufacturing process and has begun low volume pilot manufacturing of the batteries. The company believes that key markets for the batteries will include automotive, industrial, defence, aerospace, power tool and personal mobility. They could also play a key role in managing energy across the smart electricity grid.

The company’s Chief Operating Officer (COO), Pascal Boulanger spent 20 years at the CEA (French Atomic and Alternative Energies Organisation), working across a variety of fields including nuclear energy, solar photovoltaics and smart grids. In 2008, he joined one of the first R&D teams in Europe working on new nanocarbon structures: carbon nanotubes and graphene.

Within two years the team of researchers had shown that nanomaterials could be produced on a large scale and at a competitive cost. And in 2013 NAWA Technologies was born, spun off from the CEA, creating 25 jobs in Rousset, in the south of France.

Co-founder of NAWA Technologies is Sales and Marketing VP Ludovic Eveillard, who has held various senior positions in R&D with companies such as Honeywell. Technical Director is Harald Hauf, who has 23 years’ experience in the semiconductor and solar photovoltaic industries, while General Secretary is Veronique Goudet who brings with her huge experience in management, having worked in finance for Deloitte among other companies, and is a trained lawyer.

AES claims that 20MW of energy storage it deployed in the Dominican Republic just a few weeks before Hurricane Irma, assisted the island nation in keeping power supplies running even as devastation struck.

In late August, local subsidiary AES Dominicana commissioned two 10MW energy storage facilities based on AES Energy Storage’s Advancion platform, which incorporates lithium-ion batteries and forms the building blocks of the company’s grid-scale energy storage solutions. Both are able to store energy for 30 minutes duration.

Following the arrival of Hurrican Irma in the first weeks of September, Energy-Storage.News had asked AES how the Advancion arrays had coped during the extreme weather event. The company was not able to respond directly until it had collated some data and today issued a statement on the situation.

AES said the Andres and Los Mina DPP projects, both in the Santo Domingo region, “played a key role in maintaining grid stability” as both Irma and then Hurricane Maria struck. The two arrays are providing frequency control services to the grid, maintaining balance on the network as it adjusts to second-by-second mismatches in supply and demand. They also support the operation of the Republic’s interconnected electricity system, SENI.

Previously, this frequency regulation was provided by thermal plants running 24/7, but now power plants on the island can be run more efficiently, as the batteries absorb power and then discharge it as needed, quickly and cleanly. AES claims the 20MW of energy storage obviates the need for 60MW of thermal generation capacity to deliver the same level of service.

Enel subsidiary Enel Green Power North America in August closed on the acquisition of EnerNOC, paying about $250 million for the energy management company. Earlier this year, Enel Green Power bought Demand Energy Networks, showing an appetite for energy management sector. Now it appears the utility is eyeing energy storage. 

Speaking at a conference in Moscow, Starace told Bloomberg that Enel is looking for acquisitions in energy storage as the technology becomes more widespread and important in balancing the intermittency of the growing amount of renewables on grids in Europe and North America. Starace said there are already regions where batteries are commercially attractive, including the U.S., Europe and Latin America. 

European utilities are showing an increasing interest in energy storage. In July, French oil company Total completed the $1 billion acquisition of battery maker Saft. In December 2015, Germany’s E.on invested in energy storage software company Greensmith Energy Management. Greensmith was later acquired by Finnish power system manufacturer Wartsila in a $170 million deal.

Grid operators around the world continue to recognize the benefits of energy storage technologies, and one of the most intriguing applications is the ability to defer investments in conventional transmission and distribution (T&D) infrastructure.

Energy storage systems (ESSs) providing T&D upgrade deferral can be a disruptive force in the industry as they allow for a more efficient deployment of capital to meet evolving grid needs and can enable the development of new business models. T&D upgrade deferral ensures that electricity lines, substations and other equipment have enough bandwidth to handle peak demand. Navigant Research’s recent report, Energy Storage for Transmission and Distribution Upgrade Deferral, takes an in-depth look at both the opportunities and challenges in this market.

T&D systems adapt to end-user needs and the placement of generation assets. This is becoming increasingly complex because of changing demand patterns, congestion due to the development of renewable generation in remote areas, and the desire to improve the reliability of electricity supply for customers that have a growing number of alternative options to meet their electricity needs. At the same time, developing T&D systems is becoming more expensive and challenging in much of the world, leading to the demand for ESSs as an alternative to the traditional investments utilities have relied on for decades.

Falling costs, faster build times, and a smaller physical footprint make energy storage an attractive option for utilities facing the need for T&D upgrades. The table below summarizes the challenges facing T&D investments and the benefits provided by ESSs.

Enel SpA is seeking acquisitions in the energy storage business, as developments in battery technology are set to play a key role for the wider adoption of renewable sources.

Europe’s biggest utility by market capitalization sees the U.S., Europe and Latin America as the markets with the most potential, Chief Executive Officer Francesco Starace said in an interview.

“Technologies are fast approaching the point where batteries will be commercially attractive,” Starace said on Oct. 17 on the sidelines of the Open Innovations forum in Moscow. “There are parts of the world where it’s already convenient.”

While green power sources are increasingly seen as alternatives to traditional electricity, the challenge for utilities is to develop sufficient storage capacity to minimize “intermittency” and storage issues associated with solar panels and wind plants. Global storage capacity will then need to triple to 15.7 terawatt-hours by 2030 from around 4.7 this year, according to the International Renewable Energy Agency.

Rome-based Enel, which made a string of acquisitions in the sector this year, is expected to close a new deal this month in the energy management business, according to a person close to the company who asked not to be named because discussions are private.

Enel has already announced a number of deals this year, including the acquisition of software provider EnerNOC in August and of the Tynemouth standalone battery energy storage system project in Newcastle, U.K. in May.

A number of the company’s investors have said they approve of the approach, citing further growth potential.

Today, supercapacitors are found in many electronic applications. In automotive applications alone, they are used in startup systems, energy recovery solutions, and fast charge-discharge systems, to name a few. Supercapacitors can charge/discharge quickly without losing energy storage capacity over time. They also have very high power density. In contrast, batteries can store larger amounts of energy but they have a defined cycle life. A combination of batteries and supercapacitors results in a hybrid energy storage system that could help meet the needs of myriad renewable energy applications.

Supercapacitors can assist in delivering peak power while improving the performance of batteries in energy storage systems. Many supercapacitor manufacturers, utility companies, and researchers are developing hybrid capacitor-battery energy storage systems for future projects. Some are already using them in case studies and pilot projects, such as the one built by Duke Energy at its Rankin Substation in Gaston County, N.C.

Duke Energy partnered with Aquion Energy, Maxwell Technologies, and others to build a hybrid energy storage system (HESS) project. The hybrid system uses Maxwell’s UCAPs to help manage solar smoothing events in real-time—particularly when the solar power on the grid fluctuates due to cloud cover or other weather circumstances. The Aquion batteries are used to shift solar load to a time that better benefits the utility. The hybrid energy storage system integrates patented energy management algorithms.

The Maxwell UCAPs used in this program discharge and recharge power in a subsecond-to-minutes timeframe. They also boast long operational life in a wide operating temperature window. This is ideal for stabilizing short-term PV power output fluctuation in large-scale deployments, ensuring reliable access to solar power on the grid. In addition, a 100-kilowatt/ 300-Kwh battery uses a unique Aqueous Hybrid Ion chemistry (including a saltwater electrolyte and synthetic cotton separator). These materials should result in lower costs, while the water-based chemistry will provide a non-toxic and non-combustible product that is safe to handle and environmentally friendly.

The installed capacity of energy storage for microgrids is expected to increase dramatically over the next decade, with nearly 15 gigawatts of new cumulative capacity and revenue worth $22.3 billion, according to a new report from Navigant Research.

Navigant Research published a new report earlier this month investigating energy storage for microgrids (ESMG), providing an analysis of expected trends and market dynamics through the next decade, until 2026. Unsurprisingly, the report concludes that interest in ESMG technology is increasing alongside the interest in solar PV and wind deployments. While energy storage systems are not inherently required for a microgrid to operate, Navigant concludes that storage systems have nevertheless emerged “as an increasingly valuable component to distributed energy networks because of their ability to effectively integrate renewable generation.”

The report’s key highlight predicts that through 2026 there will be a cumulative installation of 14,850.7 MW (megawatts) of new ESMG capacity with revenue of approximately $22.3 billion in revenue.

“There are several key drivers resulting in the growth of energy storage-enabled microgrids globally, including the desire to improve the resilience of power supply both for individual customers and the entire grid, the need to expand reliable electricity service to new areas, rising electricity prices, and innovations in business models and financing,” explained Alex Eller, research analyst with Navigant Research. “Innovations in business models and financing will likely play a key role in the expansion of the ESMG market during the coming years.”
