Powin Energy, the Oregon-based energy storage developer, is expecting to see an uptick in non-recourse financing following a landmark project this month.

The company secured construction financing for an 8.8-megawatt/40.8-megawatt-hour battery plant in Stratford, Ontario, from Brookfield Renewable Partners, one of the largest independent renewable energy businesses in the world. 

“Securing non-recourse financing is a critical step for energy storage assets themselves, as well as the broader market,” said Geoffrey Brown, Powin Energy president, in a press release. “We believe that closing a deal of this nature with a well-respected group like Brookfield is indicative of market maturation and Powin’s future prospects.”

While the non-recourse funding model is commonplace in most renewable energy markets, the track record is more limited in energy storage. Only a handful of deals have made headlines.

Last year, for example, another Ontario project based on flywheels and lithium-ion batteries and built by Convergent Energy and Power was funded through a non-recourse finance package from CJF Capital and SUSI Partners’ Energy Storage Fund I.

“The facility reflects a non-recourse, third-party project financing structure for energy storage assets in a sector dominated by on-balance-sheet financing,” noted Convergent in a press statement.

Previously, non-recourse finance had helped fund Australia’s first utility-scale integrated solar and battery project, built by Conergy with backing from Norddeutsche Landesbank Girozentrale.

And in 2015, half the money for the Jake and Elwood battery storage projects developed by Renewable Energy Systems Americas came from non-recourse senior secured project financing debt.

Brown said he thought many energy storage projects since had been difficult to fund through non-recourse debt because of the nature of their contracts.

The new National Facility for Pumped Heat Energy Storage will bring together the former Isentropic facility and Newcastle University’s Sir Joseph Swan Centre for Energy Research to create the world’s first grid-scale demonstration of pumped heat storage.

Coupled to the electricity grid, the demonstration facility is said to include a 150kW heat pump and uses a reversible heat pump engine which converts electrical energy to heat.

Taking excess electricity from the grid, the system turns the heat pump converting electricity to thermal energy.

On the hot side, a working argon gas is compressed until it reaches 500ºC. On the cold side, argon gas is allowed to expand until its temperature falls to -160ºC.

In both cases, the gas is then passed through so-called ‘thermal batteries’ – chambers containing rocks – and gives up its energy to the storage material. The gas then leaves the store at ambient temperature.  What is left behind is a ‘hot rock battery’ and a ‘cryogenic cold battery’, both of which are able to store their energy for up to eight hours.

According to Newcastle University, to release the energy stored in the rocks, the process is reversed; the argon gas flows in the opposite direction, providing heating or cooling, or it is used to generate electricity that can be returned to the grid.

Based in Fareham, Hampshire, the £15m facility is set to become a testbed for future energy solutions and sustainable development.

Dr Andrew Smallbone, based at Newcastle University’s Sir Joseph Swan Centre for Energy Research and leading the project, said: “There are lots of people around the world talking about…energy storage systems but ours will be the world’s first grid-scale demonstration of pumped heat energy storage.

“This technology works much like a battery but at grid-scale. It is much cheaper, more sustainable and more efficient than the chemical systems that are currently planned. It also does away with the need for the hazardous and scarce materials associated with most battery technologies.

“Additionally, heat and cold are what we use most of our energy for anyway, so users get to choose the form of the energy released from the battery depending on their needs.

“The next few months will be spent plugging it into the National Grid to demonstrate how a system like this could work in the real world.”

Energy Secretary Rick Perry hailed energy storage Thursday, describing it as the “holy grail” of energy. The Trump administration, however, doesn’t share Perry’s enthusiasm for the technology, based on its budget request to Congress.

The Department of Energy’s (DOE) energy storage program would see its budget cut by 61 percent — from $20.5 million to $8 million — under President Donald Trump’s fiscal year 2018 budget proposal. The administration’s lack of interest in funding energy storage, though, hasn’t stopped Perry from touting its value.

“The holy grail of energy … is about battery storage,” Perry said Thursday at an event in Washington, D.C., hosted by Axios and NBC News. “Battery storage changes the world, I would suggest, the same way that hydraulic fracturing and directional drilling has changed the world.”

DOE’s energy storage program is housed in its Office of Electricity Delivery and Energy Reliability, whose budget would plunge from $230 million to $120 million under Trump’s proposed budget. A House-passed appropriations bill, however, would set funding for the office at $219 million for the fiscal year.

DOE’s storage program performs research and development on a wide array of storage programs, including solid state batteries, flow batteries, flywheels, and compressed air. Gigawatt-scale grid storage would improve the transmission and distribution system, resulting in lower future investments necessary to ensure grid stability. One of the barriers to lowering the cost of energy storage is that public research and development spending in energy storage has slowed down, even as reliable electric power delivery has become a higher priority.

Duke Energy is planning to develop and install battery storage materials and PV panels that will serve as part of a microgrid system at the Indiana National Guard’s Camp Atterbury in Johnson County, Indiana.

As part of the development of the site, the North Carolina-headquartered utility and holding company will also install battery storage equipment at a substation in Nabb, Indiana.

Before work can begin, plans for the project must be approved by the Indiana Utility Regulatory Commission. It would be the first microgrid installed at a National Guard facility in Indiana.

Melody Birmingham-Byrd, Duke Energy Indiana state president, said: “Given our recent success with the installation of a 17MW solar power plant at Naval Support Activity Crane, we were eager to find another opportunity to join with the US military to incorporate new technology into our grid operations. The project at Camp Atterbury will help us gain valuable operating experience and may help determine how best to expand the new technology to other areas.”

While the overall volume of energy storage deployments in the United States remains relatively modest, the technology is gaining more and more traction with utilities and policymakers, as evidenced in North Carolina Clean Energy Technology Center’s (NCCETC) latest 50 States of Grid Modernization report.

NCCETC found that among the 33 states that took legislative or regulatory action on grid modernization in Q3, 26 took some sort of action on energy storage. This includes not only the usual suspects of California, and the Northeastern states, but also an increasingly broad group of states in the South, the Mountain West and the Midwest.

In fact, among the top policy actions identified by NCCETC during the quarter is a move by regulators in both Washington State and New Mexico to require utilities to fully evaluate energy storage alongside other options in their integrated resource plans.

In many cases regulators are simply calling for utilities to deploy energy storage, and NCCETC found 14 policy actions related to storage deployment during Q3.

Utilities discover batteries

But far from having storage forced upon them, many utilities are seeking to deploy batteries and other forms of energy storage. During Q3, an administrative law judge in Texas has recommended that AEP be allowed to own battery storage, after the utility proposed deploying two battery storage systems to defer transmission and distribution investments.

NCCETC says that this trend goes beyond batteries. “Distributed energy resources are being increasingly viewed as a potential solution, rather than simply a challenge,” states Autumn Proudlove, the report’s author and manager of policy research at NCCETC.

A similar conclusion was reached by Smart Electric Power Association, which reported in September that the majority of utilities it surveyed planned to offer behind-the-meter storage programs for residential and/or commercial and industrial customers.

The research was carried out by Robert Mokaya, Professor of Materials Chemistry, and Troy Scott Blankenship, an undergraduate project student, in the School of Chemistry and has been published in the academic journal Energy and Environmental Science.

Professor Mokaya said: “We have utilised cigarette butt waste as starting material to prepare energy materials that offer unprecedented hydrogen storage properties. This may not only address an intractable environmental pollution problem – cigarette butts – but also offers new insights into converting a major waste product into very attractive hydrogen storage materials.”

Hydrogen is attractive as a fuel because whether it is burned to produce heat or reacted with air in a fuel cell to produce electricity, the only by-product is water.

Solving a major waste disposal problem

Every year nearly six trillion cigarettes are smoked worldwide. This generates more than 800,000 metric tons of cigarette butts. Apart from causing unsightly litter, cigarette butts contain contaminants such as toxic heavy metals which can leach into waterways potentially causing harm to both humans and wildlife.

Cigarette butts – used cigarette filters – are a lingering pollution hazard because they mainly contain cellulose acetate which is non-biodegradable. However, the cellulose acetate makes them an attractive starting material for valorisation to porous carbons. Such valorization is in line with the current trend to move away from coal-based carbonaceous precursors to biomass-derived or waste-based starting materials for porous carbon synthesis.

Energy flows from the Permian Basin in more forms than crude oil and natural gas. West Texas is home to some of the nation’s largest wind farms, and work has been done on developing solar and geothermal energy as well.

Now West Texas is becoming home to the development of energy storage, which will become an important piece of future energy infrastructure. Essen-Germany-based E.ON, an energy network, customer solution and renewables-focused company, has broken ground on two short-duration energy storage projects on its wind farms near Roscoe.

Texas Waves, located on E.ON’s Pyron and Inadale wind farms, consists of two 9.9 megawatt short-duration energy storage projects using lithium-ion battery technology. Texas Waves is designed to provide ancillary services to the Electric Reliability Council of Texas market in order to respond to shifts in power demand quickly and increasing reliability and efficiency. The projects will be E.ON’s second and third grid-connected lithium-ion battery systems installed in North America and are expected to be online by the end of the year.

Mark Frigo, vice president of energy storage, North America, at E.ON, provided some insight on Texas Waves via email.

MRT: This may be an elementary question, but are lithium-ion batteries already a part of the wind farm industry?

Frigo: Actually, not really. These batteries are becoming a growing part of the overall power industry, and especially the renewables industry (wind + solar) because they are becoming much more cost effective. They are a solution to the generation intermittency problem that is inherent with renewable generation.

MRT: Power is an integral part of oil and gas production, which is integral to West Texas. How can Texas Waves impact power availability?

Frigo: The Texas Waves projects will help maintain frequency regulation within the ERCOT grid. In a U.S. electricity grid, the alternating current (AC) frequency needs to be held within tight tolerance bands around 60 Hz. If the frequency falls outside of this tolerance band, generators begin to go out of synchronization triggering events that can quickly lead to catastrophic grid collapse (i.e. blackouts). Energy storage allows grids to quickly maintain that tight tolerance, thus protecting against blackouts.

MRT: What kind of jobs is this project creating and how many?

Frigo: Texas Waves has immediately created 50 construction jobs. Note that the batteries are fairly automated, and integrated into the existing Pyron and Inadale wind farms. These wind farms are managed by our West Texas team, which numbers approximately 100.
