Cleantech energy storage company Advanced Microgrid Solutions (AMS) and the Southern California-based Inland Empire Utilities Agency (IEUA) have launched a water-energy project using advanced energy storage systems to better integrate renewable power, reduce demand on the electric grid and lower costs.

IEUA, a water supplier and wastewater facility, says it has installed 3.65 MW of energy storage projects at six regional water-recycling facilities and pump stations across its service area – helping meet the water demand of a thirsty SoCal and saving the agency 5%-10% on its energy costs each year.

Notably, the storage system will also help integrate IEUA’s renewable resources, which include 1 MW of wind, 3.5 MW of solar and 2.8 MW of biofuel cell generation.

According to IEUA, the first-of-their-kind systems have already been activiated.

“We remain proud of our investments in energy efficiency, renewable generation and sustainable water management practices,” said Terry Catlin, the agency’s board president. “Energy storage is the key to maximizing the value of those investments, allowing us to use our resources more efficiently, reduce costs for our customers and participate in building a more resilient electric grid for the whole region.”

“IEUA’s leadership when it comes to water management and renewable energy is recognized across the whole industry,” added Susan Kennedy, founder and CEO of AMS. “Displaying the foresight to tackle the water-energy nexus head on is further demonstration of that leadership on behalf of the agency, the industry and water customers all throughout its service territory.”

Moving water takes a big bite out of municipal budgets, particularly in places like Southern California, which has to import so much of its water supplies. That makes water use a prime target for energy savings.

The California Energy Commission estimates that moving and treating of water, and the treatment and disposal of wastewater and the energy used to heat and consume water account for nearly 20% of the electricity consumed in the state.

In addition to existing solar and wind power, in 2010 IEUA installed the largest fuel cell system powered by renewable biogas in the world and lowered its energy consumption by nearly 25% with using energy efficiency measures. The agency also had the first public building in the nation to be awarded a LEED platinum rating.

The opportunity to reduce demand charges makes batteries especially attractive for water utilities. AMS inked a deal for 7 MW, 34 MWh of storage at the Irvine Ranch Water District last month, and in July the company secured $200 million in funding from Maquarie to construct 300 MWh of capacity resources and demand management for utilities and certain commercial, industrial water and university customers in southern California.

PV is now producing more electricity than coal in the U.K. But don’t expect a storage boom to follow.

According to GTM Research’s Global Solar Demand Monitor, the U.K. is the fifth largest market for solar demand globally — although installations are set to drop 65 percent next year due to policy uncertainty.

In addition, concerns over the eligibility for subsidies are forcing asset owners to delay adding storage to PV projects, said Jill Cainey, director of the Electricity Storage Network. 

The U.K. PV industry is largely supported through a Renewables Obligation Certificates (ROC) scheme that was designed before the advent of solar-plus-storage plant designs. 

PV asset owners wishing to add storage to their plants would have to reapply for ROC accreditation with their distribution network operator. Payments under the ROC scheme would then be suspended pending the outcome of the accreditation process. 

Even though any interim payments would still be awarded once the accreditation was granted, the temporary halt in cash flow “is something an investor would not be excited about,” Cainey said. 

This month, she attended a U.K. renewable energy trade show, Clean Energy Live, and “there were no solar farms deploying storage.” 

At the same time, the U.K. market for residential solar-plus-storage looks unlikely to take off in the near future because of unfavorable economics. 

Recent research by Delta Energy & Environment suggests the payback time for U.K. residential PV-plus-storage could be 16.9 years for a new system and 24.5 years for a retrofit, not taking subsidies into account.

One of the top electric vehicle charging station firms in the US, EVgo, has won an Energy Storage North America 2016 Innovation Award for its Stationary Storage + Electric Charging (SSPEC) project, according to an email sent to CleanTechnica.

To explain, the EVgo SSPEC project was created to help develop ways of lowering the cost and immediate power demand of electric vehicle (EV) charging to host facilities. To be more specific, it explores the incorporation of energy storage with DC Fast Charging infrastructure.

The project used 4 BMW Group 2nd-life batteries taken from retired test fleet EVs. The batteries were used alongside a solar photovoltaic (PV) system and intelligent site power control.

“DC Fast Charging plus storage presents an exciting opportunity for drivers and charging companies alike,” stated Terry O’Day, Vice President, Product Strategy and Market Development at EVgo. “This project has the potential to shortcut some of the barriers facilities face when looking to install DC Fast Charging stations by reducing operating costs, improving charging service and convenience for EV drivers, and ultimately can help to put more electric vehicles on the road.”

The email provides more information: “For the SSPEC project, EVgo partnered with the University of California San Diego, which is recognized as one of the top 15 research universities worldwide and operates what is considered one of the world’s most advanced microgrids. EVgo worked with UC San Diego to locate a demonstration site on the campus microgrid that would also ensure the stations would be accessible to the public and which results in the chargers serving over 100 drivers per week. The project is part of the CPUC Technology Demonstration Program, a program designed to help demonstrate the benefits of energy storage coupled with public DC Fast Charging stations.”

A boom in desalination could create new opportunities for energy storage as developers seek to maximize output from assets powered by wind or solar.

“As soon as solar-plus-storage can compete with [traditional] generation prices, there will be a huge market,” said Thomas Hillig, managing director of Dr. Thomas Hillig Energy Consulting, a consultancy focused on off-grid energy markets.

“It’s pretty important to have high utilization, because the desalination equipment is very capital-intensive. After having done the investment, they want to run it as intensely as possible. If we go off-grid, there has to be storage because utilization has to be high.”

Currently the market for energy storage attached to desalination plants is still in its infancy because of the cost of batteries. With most desalination projects, “You pretty much have the choice of where to put them,” Hillig noted.

In such cases, developers will naturally tend to choose locations where energy is cheap and plentiful. Thus, for the vast majority of desalination plants today, solar-plus-storage is still “not feasible. It’s a nice concept; a market of the future,” he said. 

But the picture is changing as demand for desalination grows and solar-plus-storage becomes more competitive. Currently, desalination serves around 1 percent of the global population, or almost 746 million people.

But desalination capacity increased 57 percent between 2008 and 2013, according the market research organization Global Water Intelligence (GWI) and the International Desalination Association.

GWI said desalination could be needed for up to 14 percent of the world population by 2025, based on United Nations figures for water scarcity. Renewable energy is already being considered as the power source of choice for many new desalination projects.

In the concluding chapter for the World Energy Council’s World Energy Resources 2016report, DNV GL asserts that energy storage is playing an increasingly crucial role in the transformation to a cleaner, smarter, safer energy future worldwide.

“Energy storage is pivotal to meeting the challenges facing economies worldwide,” says Paul Gardner, lead author. “With this chapter, which follows sections on a variety of generation resources and technologies, we hope to present the challenges and opportunities in energy storage with a thorough examination of the economic, regulatory and commercial factors surrounding it.”

The chapter examines technical, financial, environmental and regulatory aspects of a variety of energy storage technologies including lithium-ion and flow batteries. It looks at the impact of increasing amounts of battery storage, and battery capacity in electric vehicles. Graphs depict storage technologies according to performance characteristics, using energy capacity and discharge time at rated power. Information gathered directly by PwC shows the levelised cost of storage in 2015 compared to the cost of 2030 in a bar graph, showing a projected decrease in future prices.  The chapter develops three major conclusions:

1. The main areas of growth in the next five years are likely to be in small-scale battery storage in conjunction with solar PV; in utility-scale electricity storage; in electric vehicles; in commercial, communications and software capabilities to allow DER to be aggregated, in a ‘virtual power plant’ or ‘swarm’; in pumped storage hydro; and in islanded use cases integrating renewables.
2. Most commercial interest is in battery storage and the costs of several storage technologies will fall as production volumes increase.
3. The future outlook for energy storage markets is good due to an increasing need, but the regulatory and legal frameworks are failing to keep pace.

According to the World Energy Council, the investment community has good reason to be excited about the innovation and business models that will emerge from new opportunities. With the cost of capturing and storing wind and solar energy coming down, its deployment across the world will increase.
