The developers of the lithium-ion battery won the Nobel Prize in Chemistry 2019, in recognition of a scientific achievement that has helped power our mobile phones, laptops, and electric vehicles (EVs).

“It can also store significant amounts of energy from solar and wind power, making possible a fossil fuel-free society,” The Royal Swedish Academy of Sciences said, noting that lithium-ion batteries have created a rechargeable world over the past decade.

In the new decade, batteries and battery technology are set to play an increasingly important role in bringing more electric vehicles and renewable energy to the market, analysts say.

Rapidly declining costs and the potential to scale up existing and breakthrough battery and energy storage solutions are set to dramatically change the global mobility market and the power grid over the next ten years.

A lot of investments will be necessary in scaling up emerging battery and energy storage technology, as well as in the further development of lithium-ion batteries and alternative battery tech, to support the clean energy transition while global demand for electricity continues to rise.

Continuously falling battery costs, and rising capacity and usage of clean energy are set to result in booming global stationary energy storage over the next two decades, which will require total investments of as much as US$662 billion, BloombergNEF (BNEF) said in a report last year.

Energy storage installations across the world are expected to soar to 1,095GW, or 2,850GWh, by 2040, compared to a modest deployment of just 9GW/17GWh as of 2018, according to BNEF’s forecasts.

Unsurprisingly, the key driver of the energy storage installation boom will be additionally plunging costs of lithium-ion batteries, which will give financial rationale to additional uses of storage and surging installations of stationary energy storage.

According to BNEF, the exponential rise in renewable-sourced electricity and EV use will transform the global power systems and the transportation sector, driving demand for energy storage.

“The report finds that energy storage will become a practical alternative to new-build electricity generation or network reinforcement,” according to BNEF’s analysts.

According to UBS, energy storage will be the next critical catalyst for a global shift towards renewable energy. Current energy storage capacity represents just 17 percent of total installed solar and wind capacity, UBS said in a report in November.

“Energy storage cost has almost halved in the past five years but generally remain too pricey for scale-up applications,” UBS says.

Kyocera Corporation and 24M announced that Kyocera has formally launched its residential energy storage system, Enerezza, the world’s first system built using 24M’s novel SemiSolid electrode manufacturing process. In addition, Kyocera has extended its commitment to 24M’s unique manufacturing platform with plans to start full-scale mass production in the fall of 2020.

In June 2019, Kyocera began pilot production of 24M’s SemiSolid battery technology to validate its use in residential energy storage systems in the Japanese market. Based on the successful pilot, Kyocera recently rolled out its full Enerezza product line — a 24M-based residential energy storage system available in 5-kWh, 10-kWh, and 15-kWh capacities designed to meet diverse customer needs.

“Kyocera and our customers benefit from long battery life, unparalleled safety, and the low-cost approach enabled by 24M’s unique manufacturing process,” said Toshihide Koyano, Deputy General Manager of Corporate Solar Energy Group at Kyocera. “At Kyocera, we believe that 24M’s SemiSolid technology is the emerging standard for lithium-ion battery manufacturing. We are delighted to be the first company to deliver residential energy storage products using 24M’s novel process.”

24M’s innovative manufacturing process delivers market-leading price-performance. SemiSolid electrodes use no binder, mixing electrolyte with active materials to form a clay-like slurry with unique attributes. As a result, the 24M process eliminates the need for a significant amount of inactive materials and capital-intensive processes like drying and electrolyte filling, thus dramatically reducing manufacturing cost.

“Kyocera’s launch of the Enerezza residential energy storage product line marks a significant milestone for 24M,” said Naoki Ota, President and CTO of 24M. “After many years of hard work, our technology is commercially available thanks to our dedicated partner Kyocera.”

It has not been stated whether Enerezza will be made available to the U.S. market.

‘Leapfrogging’ the grid: Hybrid lithium-flow in action at a remote Thai village microgrid

We talk a lot about the existing prominence of lithium-ion. There’s also been an increasing amount of discussion of flow batteries as a long duration counterpart to lithium, evidenced by the popularity of our November news story on Lockheed Martin’s forthcoming flow energy storage battery launch (see our Top five news stories for the year here).

I was both surprised and enthused to see a guest blog on a project combining both technologies, lithium-ion batteries with zinc bromine flow batteries, at a remote Thai village, take the number one spot for this year.

Ben Shepherd, chief commercial officer at Australian company Redflow, talked about the advantages, challenges and execution of a project that promises to prove “an excellent demonstration of the benefits of energy storage systems in developing nations”.

A flow battery ‘competitive with the LG Chems and Samsungs of this world’

Ditto the second entry in our list: the proposed merger between flow energy storage providers Avalon Battery and redT was discussed in detail with Avalon and redT leadership, alongside NEXTracker’s CTO, Alex Au.

NEXTracker has deployed Avalon’s batteries in the field already in its innovative solar-plus-storage power plants. Some deep insights as well as attention-grabbing soundbites from the bullish trio propelled this one into the upper echelons of our Top 10 blogs of the year.

An oft-repeated refrain—the sun doesn’t always shine, and the wind doesn’t always blow—is sometimes seen as an impediment to renewable energy. But it’s also an impetus toward discovering the best ways to store that energy until it’s needed.

Declining costs in available technologies have propelled interest in energy storage forward like never before. The price of lithium-ion batteries has fallen by about 80% over the past five years, enabling the integration of storage into solar power systems. Today, nearly 18% of all electricity produced in the United States comes from renewable energy sources, such as hydropower and wind—a figure that is forecast to climb. And as communities and entire states push toward higher percentages of power from renewables, there’s no doubt storage will play an important role.

Compared with the same period a year earlier, the United States saw a 93% increase in the amount of storage deployed in the third quarter of 2019. By 2024, that number is expected to top 5.4 gigawatts, according to a forecast by market research firm Wood Mackenzie Power & Renewables. The market value is forecast to increase from $720 million today to $5.1 billion in 2024. Driving such growth is an increased focus on adding renewable energy sources to the nation’s grid.

Only in the past decade has the widespread adoption of renewable energy sources become an economic possibility, said Paul Denholm, a principal energy analyst at the National Renewable Energy Laboratory (NREL). He joined NREL 15 years ago and, at the time, he and other analysts were busy plotting a path to 20% of the nation’s energy supply coming from renewable sources. Now, they’re aiming much higher.

“The declining cost of wind and solar and now batteries makes it conceivable to consider 100% renewables,” he said.

NREL’s Renewable Electricity Futures Study estimated that 120 gigawatts of storage would be needed across the continental United States by 2050, when the scenario imagined a future where 80% of electricity will come from renewable resources. The country currently has 22 gigawatts of storage from pumped hydropower, and another gigawatt in batteries.

Energy storage is a rapidly growing segment of the clean energy sector, and prices are dropping fast. Yet many are still struggling to understand how to value energy storage as an investment.

As a growing number of cities, states and businesses commit to 100 percent clean energy, storage is already playing a pivotal role in determining how they will meet these targets. Wood Mackenzie’s latest Global Energy Storage Outlook projects that deployments will grow 13-fold over the next six years, from a 12-gigawatt-hour market in 2018 to a 158-gigawatt-hour market in 2024.

This emerging market represents a huge opportunity. Global investments of $374 billion a year will be needed to upgrade the grid with enough flexibility to account for the variable power generation profiles of renewable technologies like solar and wind. Storage solutions are now a growing part of this energy transition and will represent a $150 billion industry in the U.S. alone by 2023.

However, massive deployment numbers and dropping costs won’t streamline project finance for energy storage in the short term. As a nascent industry, battery storage lacks historical data, requiring investors and lenders to familiarize themselves with its unique qualities.

Installing storage, whether as a standalone asset or by adding it to an existing utility power source, is highly individualized from one project to another. So extrapolating risk and returns from any given asset is not straightforward. Each project draws power from a unique generation source (renewable or traditional power plants) and is interconnected to a regionally regulated power market and a unique revenue stream.

Some storage projects are able to generate income both while charging and deploying energy, while others are focused just on deployment. There are also interconnection considerations depending on how and where your storage project plugs in. Are you directly charging from the grid? From a solar or wind farm or some other standalone generation facility?

Another consideration for investors is that batteries in a storage project have shorter lifespans of 10 to 15 years versus solar or wind energy assets that may last twice as long. And similar to PV modules, which lose efficiency as they age, it’s critical to understand the factors that impact a battery’s ability to store energy as it ages and to factor in the cost of replacement as needed. Understanding the intricacies of asset management and optimization is highly complex, but it is necessary in order to adequately mitigate risk for each storage portfolio.

To realize the full potential for the investment markets and the global energy transition, it’s critically important to understand the entire value stack that integrated storage brings to the table.

January 2 (Renewables Now) – Gresham House Energy Storage Fund Plc (LON:GRID) has completed the acquisition of a 49-MW battery-only project near Preston, northern England, it said on Thursday.

Gresham House acquired the Red Scar project for a total enterprise value of about GBP 32.8 million (USD 43.1m/EUR 39.2m) from developers Gresham House DevCo Ltd and Noriker Power Ltd.

Red Scar was handed over on December 31, after the successful completion of commissioning tests and grid connection. It is one of the exclusive portfolio projects being developed by subsidiaries and associates of Gresham House plc (AIM:GHE) for sale to the fund and included in Gresham House Energy Storage Fund’s initial public offering (IPO) prospectus, published in October 2018. The project brings the total capacity of operational battery storage projects in the fund’s investment portfolio to 174 MW.

The fund expects to buy another three projects in the coming months after they become operational, it said. These include two 50-MW projects and a 5-MW extension to the 8-MW Littlebrook project in Kent.

Liam Stoker and Andy Colthorpe reflect on the biggest news in energy storage in 2019, while also gazing into their crystal balls and predicting what the energy transition may hold in store for the year ahead.
