Many of the innovations happening in the energy sector involve solving intermittency issues brought to the table by renewable energy darlings like photovoltaic solar and wind generation.

With photovoltaic solar providing the bulk of its energy during off peak hours and wind turbines unable to generate anything on a windless day, the energy sector has its work cut out for it to improve the reliability of a new generation of energy producers.

Energy storage — which has been called the secret sauce to solar — could be the answer to those problems. But energy storage needs to be coupled with smart and micro-grid implementations and, of course, a diverse energy portfolio.

“I think now is the time to be investing in alternative technologies that have the ability to deliver what is actually required, as opposed to just deliver based on a mandate or a feel-good exercise,” says Chris Davey, president at EnviroMission, a solar tower developer, and co-executive director of the Arizona Energy Consortium.

Unique places, unique deals

It’s not as sexy as new ways to power your home, but new types of deal structures and ways of financing projects make energy projects unique and challenging prospects.

Not only that, but these new ways to generate power can tie in with the idea of a smart city, where energy generation is implemented into various parts of the community.

Lynne L’Esperance, associate vice president of power and utilities at Arcadis North America, works with clients on how to convert a distressed or under-utilized property into an income (energy) producing asset.

Recently, Arcadis worked with a town, developers and a utility to turn a 15-acre landfill into a 2.36-megawatt solar plant, L’Esperance says.

The strategic alliance turned the closed landfill into something from which everyone could benefit, as the city leased the land to the solar developers while the utility purchased the power to serve the town.

These types of partnerships can turn sites of blight into community assets. At the same time, developers can create assets with dual uses. A simple parking lot can be turned into a solar generator with the implementation of solar shade sites (look no further than ASU’s Tempe campus to see these in action).

“Arcadis has been working with clients across the world in this smart city phase where we look at how you can make the most out of assets or potential liabilities that you have,” L’Esperance says.

DANBURY, Conn., May 30, 2017 (GLOBE NEWSWIRE) —  FuelCell Energy, Inc. (Nasdaq:FCEL), a global leader in delivering clean, innovative and affordable fuel cell solutions for the supply, recovery and storage of energy, today announced that it was awarded  a $3.0 million contract from the Advanced Research Projects Agency-Energy (ARPA-E) division of the U.S. Department of Energy (DOE) to advance the commercialization of cost-effective and clean long-duration energy storage. The project will further develop FuelCell Energy’s advanced solid oxide cell technology capable of alternating between electrolysis and fuel cell power generation mode (reversible SOFC, or RSOFC) in an energy storage application.  RSOFC systems can produce hydrogen or other carbon-neutral fuels in electrolysis mode and later convert the stored fuel to power in electrolysis mode.  This project was awarded under ARPA-E’s Renewable Energy to Fuels through Utilization of Energy-Dense Liquids (REFUEL) program.  

“FuelCell Energy is commercializing reversible solid oxide systems for energy storage, and this project will further advance the initiative including the evaluation of our reversible fuel cell’s ability to produce and use hydrogen and other fuels,” said Tony Leo, Vice President of Advanced Applications & Technology Development for FuelCell Energy. “The capability of this fuel cell configuration to produce and consume hydrogen or other carbon-neutral fuels for energy storage, and to cleanly and efficiently generate electricity when needed by the electric grid offers exciting possibilities for integration of intermittent renewable power.”

The use of reversible fuel cells to efficiently produce hydrogen or other carbon-neutral fuels offers unique opportunities for efficient energy storage, particularly for the long-duration storage applications that will become important as penetration of intermittent renewable power increases.  Discharge duration can be increased by adding more fuel storage, without the need to increase the number of fuel cells, enhancing the affordability of extended duration energy storage.

“Critical to any storage solution is affordability, which is why the high round trip efficiency of this reversible fuel cell and the utilization of a cost-effective energy storage medium for long durations is so compelling,” continued Mr. Leo

LG CNS, a leading energy solutions and services provider across energy storage, microgrids, renewable energy and smart cities sectors, was awarded a $43 million contract by the Guam Power Authority (GPA) to deliver, operate and maintain two Energy Storage Systems (ESS) that combined can deliver 40 megawatts (MW) of power output. The contract, celebrated at a ceremony on May 15, 2017, marks LG CNS’ largest ESS project to date.

The project will reduce the intermittent power outages Guam is experiencing due to increasing net metering penetration and utility scale renewable projects. Further, the project will help GPA prepare the grid as it works toward reaching a renewable goal of 25 percent by 2035. Plans call for a 24 MW ESS for frequency regulation to be located at a substation in the village of Agana, and a 16 MW ESS for renewable integration to be installed at a substation in the village of Talofofo, which is connected to an existing solar farm.

Under terms of the agreement, LG CNS is responsible for delivering the ESS systems on a “turnkey” basis within 12 months. The systems will utilize LG Chem lithium-ion batteries and LG CNS’ own Energy Management System (EMS) to provide frequency regulation and solar photovoltaic (PV) ramp rate control. The project includes a 25-year operations and maintenance agreement.

The Guam ESS project is of strategic importance for LG CNS on a number of fronts. As an island 3,000 miles away from the nearest main landmass, Guam is positioned to become a prime example of the growing global microgrid market for isolated electric utilities. The Paris Agreement of the United Nations Framework Convention on Climate Change has triggered interest in renewable energy-based, self-sustainable microgrids, in which ESS plays a critical role.  

Guam also serves as a strategic base for expansion into various markets, including Hawaii and the U.S. mainland to the east, Australia to the south and Southeast Asian countries to the west.

Upon completion, LG CNS will have deployed over 125 MW of energy storage projects, further enhancing its position as one of the global market and technology leaders for ESS. LG CNS was ranked as No. 1 in Asia and No. 7 globally in the latest Utility-Scale ESS Integrators Leaderboard by Navigant Research.

GTM Research expects annual U.S. ESS deployments to reach 2.6 GW and become a $3.3 billion market by 2022. Outside the U.S., a 2017 World Bank Report projected the ESS market to grow to $24 billion by 2025, mainly through growth in East Asia and Pacific regions.

Younicos announced Monday it will deliver a megawatt-scale battery storagesystem to Austin Energy in Texas.

The project is part of a U.S. Department of Energy-funded initiative known as the Sustainable and Holistic Integration of Energy Storage and Solar Photovoltaic (SHINES) project. Younicos will collaborate with the project’s prime contractor, Doosan GridTech, to install the 1.75 MW / 3.2 MWh system using the company’s Y.Cube systems.

“We’re keeping Austin weird – and energized,” said Stephen L. Prince, CEO of Younicos. “The SHINES project is the perfect showcase for an alternative, distributed energy system with resources like energy storage providing resiliency and security. Our Y.Cube is ideal for this application – offering the best in battery storage, intelligent control, system performance and safety in a compact form factor. We’re very pleased to partner with Austin Energy and Doosan GridTech on this innovative project.”

Younicos’s Y.Q software platform will manage the system, communicating with the Doosan GridTech Intelligent Controller using the Modular Energy Storage Architecture (MESA) open standard. The seven Y.Cubes and Y.Converters represent the company’s largest Y.Cube deployment in the U.S. to date.

Daejin Choi, CEO of Doosan GridTech commented, “We are pleased to be working with Younicos on this breakthrough project. The MESA open standard provides the software architecture that allows us each to bring our innovation to Austin Energy without a lot of custom engineering to fit the pieces together. Austin preserves choice in their system moving forward and we each get to focus on our core competencies.”

The Y.Cube systems will provide storage capabilities as part of a Distributed Energy Resource Management System (DERMS) that will maintain grid reliability while also enabling energy loads to be delivered at the lowest possible cost with high penetration levels of distributed PV generation. The platform, called DG-DERO, also provided by Doosan GridTech, will use multiple advanced control methodologies that will be demonstrated and evaluated using a fleet of diverse DER assets deployed at various locations among Austin Energy’s customers.

The battery system will be located in a neighborhood in East Austin, coexisting near both residential and commercial buildings.

Developing international standards is vitally important to the growth of grid-scale energy storage systems. These systems can make it possible to feed power to the grid so that production need not be scaled up and down repeatedly to adjust to changing demand levels. They also absorb the over-generation from wind and solar-power facilities and release that power when needed. The MESA (Modular Energy Storage Architecture) Standards Alliance is an industry group of dozens of equipment vendors and utilities working together to grow the energy storage industry by developing an open, non-proprietary set of specifications and standards. Our goal is to accelerate interoperability, scalability, safety, quality, availability, and affordability in energy storage components and systems.

This standardization effort has two main aspects. The first is a software control platform that allows all equipment from different vendors to talk the same “language,” so that when one piece of equipment sends a command or transmits data, it is received and interpreted correctly by the intended recipient.

The second aspect is ensuring that the hardware that makes up an energy storage system (ESS)—the batteries, power converters, metering system, and the energy management system (EMS) − can be intelligently “plugged into” each other and the electrical system.

In turn, the ESS must be intelligently plugged into the utility’s existing information and operations technology. Without established standards, components and systems will come with proprietary connectors, and the process of plugging them together becomes a laborious task repeated for each new project, which will add to project cost and lead time.

The MESA Standards Alliance is currently providing two specifications:

• MESA-ESS is designed to let electric utilities or grid operators scale deployment of energy storage and manage energy storage assets and fleets of multi-vendor assets to meet specific needs and use cases with minimal custom engineering
• MESA-Device Specifications and SunSpec Energy Storage Model address how energy storage components within an energy-storage system communicate with each other and its operational components.

A world first hybrid renewables trial, pairing a grid-connected wind farm with lithium-ion battery storage and energy management software, has been switched on in Spain, in a bid to boost the integration of variable-generation renewables into electricity networks around the world.

The project, led by Spanish wind energy giant Acciona, will use in-house developed “simulation” software to control the battery storage systems at a specially developed hybrid power plant, which is located next to Acciona’s experimental wind farm at Barasoain (Navarra).

The storage system has two batteries in separate containers: one a fast-response 1MW/0.39MWh battery that can maintain 1MW of power for 20 minutes; the other a slower-response battery with greater autonomy that can maintain 0.7 MW for 1 hour.

Both of the Samsung SDI-supplied batteries will be connected to a 3MW Acciona wind turbine – one of five that make up the Barasoain Experimental Wind Farm – and will store energy produced by the turbine when required.

The installation also has three other units: one for medium voltage cells and analyzers, another for inverters/chargers and a transformer (installed by Ingeteam, a company participating in the project), and a third for the control and monitoring equipment.

Acciona says that he main aim of the trial is to use the software and grid-connected storage solutions to optimise the quality of the wind energy that is sent to the grid.

It will also test the plants ability to provide ancillary services to the electric power system – necessary to maintain a continuous balance between supply and demand – and to shift supply to match periods of higher demand, thus improving the economic performance of the wind farm.

The project has received funding from the European Regional Development Fund (ERDF), which manages the Spanish Centre for Industrial Development (CDTI).

And the Acciona-developed software – or ‘ADOSA’ (Analysis, Dimensioning and Optimisation of Storage Systems) – recently won the top prize from the Spanish Wind Energy Association, in the field of R&D.

“The application of electric power storage systems using batteries connected to wind farms and solar plants is a field with great growth potential due to the major development of renewable energies worldwide, lower battery technology prices and improved efficiency,” Acciona said in a media statement on Tuesday.
