Energy Storage 2019

March 18th, 2019 by Sponsored Content

By Steve Hanley

Energy storage in the United States is expected to triple in 2019 according to Climate Action. That makes for a great headline, but what does it mean? Let’s begin by defining what energy storage is and why it’s important.

Types Of Energy Storage

Electricity is an enigma. We know what it can do, we know how to make it, we know how to control it, but there is not one person living today who can tell us what it is. Some scientists think it is a wave, some think it is made up of tiny particles, some think it is both.

What we do know is that unless it is stored in some fashion, it must be used as soon as it is created or it will be wasted. The oldest method of storing electricity is called pumped hydro. Here’s how it works.


Pumped Hydro

Excess electricity is used to pump a large quantity of water uphill into a holding pond. Later, the water is allowed to flow downhill to a reservoir below, spinning turbine blades to generate electricity along the way.

The process is about as high tech as a brick but it is simple and effective. It does require a lot of open territory with great deal of elevation change, so it is not suitable for use in many parts of the world.


Other Energy Storage Techniques

There are many other ways to store electricity ranging from the dead simple to the extremely complex. A California company proposes to build a railroad to nowhere. A train of electrically powered boxcars filled with cement would churn their way uphill in the day time using excess electrical energy. At night when the supply of solar power decreases, the train would roll back downhill. At that point, the electric motors that pushed it uphill during the day would reverse their role and generate electricity on the way down.

Other ideas include a tower that stacks concrete filled barrels on an elevated platform during the day. Later, lowering them back to ground level would generate more electricity.

Both systems use sound scientific principles that convert energy into work and then later reverse the process to make more electricity. Despite being possible, neither has shown itself to be price competitive with battery storage.

Concentrated solar power plants do not harvest the light of the sun. Instead, the capture the heat contained in sunlight and use it to warm a storage medium such as salt or silicon. Later, that heat is used to heat water to make steam that drives conventional generators that make electricity.

One experimental system heats silicon until it glows white hot. That light is then used to create electricity using solar panels. Once again, the so-called “sun in a box” concept is physically possible but not yet price competitive with battery storage.


Battery Storage

The most common form of electrical storage today is lithium ion batteries. While they may feature several different battery chemistries, they are essentially the same as the battery cells used in electric vehicles.

The driving factor that makes this type of storage preferred is that the cost of lithium ion battery cells continues to decrease as more and more of them are manufactured.

Another type of energy storage is known as a flow battery. It features two large tanks separated by a membrane. One liquid has a positive charge, the other a negative charge, Flow batteries have one advantage over lithium ion batteries — to add more capacity, simply make the tanks larger.

China is pushing forward with plans to install more flow batteries but in the US, lithium ion batteries are the storage medium of choice largely because they are the least expensive choice.


US Energy Storage Booming 


A new report from the Energy Storage Association and GTM Research says battery storage in the US grew by 27% in 2018 with 431 megawatt-hours installed.

But here’s where things get interesting. ESA and GTM Research predict 2019 will see triple that amount installed — 1,233 megawatt-hours with a combined value of more than $1 billion.

Things get even better from there. By 2023, they expect the US market for battery storage to soar to $3.8 billion helped by “falling costs and favorable policies” on the state level, according to Ravi Manghani at GTM Research.

Kelly Speakes-Backman, CEO of ESA says “policies and regulatory frameworks that level the playing field will further encourage energy storage deployment throughout 2018 and beyond as the industry builds toward a goal of realizing 35 GW by 2025.”

Time Shifting

What makes battery storage so valuable is its ability to save electricity generated now to be used later. That’s a big deal because solar panels work best during the day but begin to lose power as the sun sets — just when people are getting home from work and starting turning on appliances like air conditioning and electronic devices.

If if were not for batteries, much of that solar energy would be wasted. The same goes for wind power. Often wind turbines generate more electricity than needed at some times of day. With batteries, that excess energy can be stored for use later.


Frequency Stabilization

Another important characteristic of battery storage is the ability to react in milliseconds to the tiny variations in the frequency of the electricity flowing through the electrical grid. In most of the US, the electricity supplied by utility companies oscillates 60 times a second.

Motors, computers, and other digital devices can be damaged if the frequency is allowed to vary by as little as 1%. Batteries can absorb excess frequency changes or supplement the grid if the frequency drops too low.


Falling Prices For Energy Storage

The cost of battery storage is accelerating the demand for battery storage. And that is driving a sea change in the utility industry. Unthinkable just a few years ago, building new wind and solar farms coupled with battery storage is now less expensive than constructing new generating facilities powered by natural gas. They are also less expensive that continuing to operate nuclear or coal powered plants.

In the utility industry, investments often take 3 to 4 decades to pay off. The idea of closing down existing facilities in favor of new renewable plus storage options means trillions of dollars in existing investments are at risk. No wonder there is strong resistance to renewables plus storage by some utility companies anxious to protect their existing 🦕🦖 facilities.

But price will win out and the lower the price of renewables plus storage gets, the sooner those existing 🦕🦖 facilities will be retired whether is is convenient for their owners or not.

Agelbert NOTE: The comments section to the above article is quite lively. ;D  Some advocates of Hydrogen gas storage weighed in. Some fossil fuelers weighed in claiming "natural" (LOL!) fracked gas stored in caverns or whatever is "cheaper" than pumped hydro storage. That's a bold face lie simply because it fails to ADD to the costs of Fracked CH4 the subsidies we-the-people are coerced out of AND the pollution costs we-the-people get stuck with. All those costs are ABSENT with pumped storage.

As to Renewable Energy generated Hydrogen gas storage, though it is not polluting, it is not economically feasable on a large scale (which is how Renewable Energy energy storage MUST be scaled for a 100% plus Renwable Energy powered civilization), for reasons I outlined in a comment I made (see below).

Quote
freedomev > Matthew Young
No they haven't stored H2 underground. Why?
Please show examples?
And yes so much NG seeps away it's HG effect is as bad as coal.
And H2 is 100x smaller and even seeps through steel.
And why do you think there is no natural H2?
Because it is very reactive and bonds with many things. Thus why there is NG but no natural H2.
The H2 either became methane/HCs, water or rock.
Quote
Ed Golla > freedomev
Hydrogen is not very reactive at all at ambient temperatures. There is natural Hydrogen in the atmosphere. Of course it is only about 1/2 part per million. Hydrogen is not in the atmosphere to any great extent because it speed is so great that it is able to escape from the earth's gravity at the upper limits of the earth's atmosphere.

agelbert > Ed Golla

The reactivity of Hydrogen gas is not the main issue with the effective storage of hydrogen gas as a form of energy for quick use.

The main issue is that Hydrogen gas molecules are smaller than any molecules in the container they are stored in (unless you can lower the temperature so much that the H2 becomes liquid - which uses enormous amounts of energy to do).

At ambient temperatures, the Hydrogen gas will percolate through metal or salt or even the densest of soils. Metal containers (see Nuclear power plant Tritium woes) degrade from Hydrogen gas caused embrittlement within a few years.

Pumped storage is, at present, the cheapest and most reliable method of storing electrical energy.

If the following type of system I learned about (in a January 18, 2018 Spiegel article) was adopted worldwide, the 100% Renewable Energy economy, including transportation, would quickly become a reality:
 

German company plans large-scale power storage using massive rock block

Hydrogen gas, in liquid form, is the best type of rocket fuel. It has the highest energy density of any rocket fuel, but it can never compete with pumped storage for infrastructure energy demands.

Much progress is being made. Battery banks like the one Tesla is marketing will have their place in the 100% Renewable Energy economy, although I believe pumped storage, with giant rock pistons over a giant cylinder of water underground, as shown above, will be more prevalent. We need fossil fuels like a dog needs ticks, no matter what the denier naysayers say.

Here's a nice video one fellow posted showing Amory Lovins exploding Fossil Fuel Industry and Nuclear Power Industry Propagated Baloney (i.e. Myths - Amory is always polite :D) AND showing how quickly battery costs are going down.

The Liquid Metal Battery: Innovation in stationary electricity storage
36,376 views


Energy Futures Lab

Published on Jan 18, 2019

On 29 November 2018 Energy Futures Lab and the Dyson School of Design Engineering hosted Professor Donald Sadoway of MIT to discuss the impact the liquid metal battery could have on the future of gridscale energy storage.

Abstract

Massive-scale electricity storage would offer huge benefits to today’s grid, reducing price volatility, improving stability against loss of power, increasing utilization of generation assets by enabling us to design towards average demand instead of peak demand, and deferring the costs of upgrading existing transmission lines. When it comes to tomorrow’s grid, storage is key to widespread integration of renewables, i.e., solar and wind, which due to their inherent intermittency present challenges for contribution to base load.

Comprising two liquid metal electrodes and a molten salt electrolyte, the liquid metal battery offers colossal current capability and long service lifetime at very low cost, i.e., the price point of the electricity market. The round-trip efficiency of these batteries is greater than 80% under daily 4 h discharge (C/4). Fade rates of 0.00009%/cycle have been measured which means retention of of more tahn 99% of initial capacity after 10 years of daily cycling at full depth of discharge. There is much to be learned from the innovative process that led to the discovery of disruptive battery technology.

Biography

Donald R. Sadoway is the John F. Elliott Professor of Materials Chemistry in the Department of Materials Science and Engineering at the Massachusetts Institute of Technology. His B.A.Sc. in Engineering Science, M.A.Sc. in Chemical Metallurgy, and Ph.D. in Chemical Metallurgy are all from the University of Toronto. He joined the MIT faculty in 1978. The author of over 170 scientific papers and holder of 28 U.S. patents, his research is directed towards the development of rechargeable batteries as well as environmentally sound technologies for metals extraction.

He is the founder of two companies, Ambri and Boston Metal. Online videos of his chemistry lectures hosted by MIT OpenCourseWare extend his impact on engineering education far beyond the lecture hall. Viewed 1,800,000 times, his TED talk is as much about inventing inventors as it is about inventing technology. In 2012 he was named by Time magazine as one of the 100 Most Influential People in the World.

Energy Vault Lands $110M From SoftBank’s Vision Fund for Gravity Storage

The investment is large by the standards of most startups, but it’s in keeping with the capital costs Energy Vault will face in scaling up its technology.

JEFF ST. JOHN AUGUST 15, 2019

Building toward the future.

Energy Vault, the Swiss-U.S. startup that says it can store and discharge electrical energy through a super-sized concrete-and-steel version of a child’s erector set, has landed a $110 million investment from Japan’s SoftBank Vision Fund to take its technology to commercial scale.

Energy Vault, a spinout of Pasadena-based incubator Idealab and co-founded by Idealab CEO and billionaire investor Bill Gross, unstealthed in November with its novel approach to using gravity to store energy.

Simply put, Energy Vault plans to build storage plants — dubbed “Evies” — consisting of a 35-story crane with six arms, surrounded by a tower consisting of thousands of concrete bricks, each weighing about 35 tons.

This plant will “store” energy by using electricity to run the cranes that lift bricks from the ground and stack them atop of the tower, and “discharge” energy by reversing that process. It’s a mechanical twist on the world’s most common energy storage technology, pumped hydro, which “stores” energy by pumping water uphill, and lets it fall to spin turbines when electricity is needed.

CEO and co-founder Robert Piconi said in a November interview with GTM that the standard array would deliver 4 megawatts/35 megawatt-hours of storage, which translates to nearly 9 hours of duration — the equivalent of building the tower to its height, and then reducing it to ground level. It can be built on-site in partnership with crane manufacturers and recycled concrete material, and can run fully automated for decades with little deterioration, he said.

And the cost, which Piconi pegged in the $200 to $250 per kilowatt-hour range, with room to decline further, is roughly 50 percent below the upfront price of the conventional storage market today, and 80 percent below it on levelized cost, he said.

The result, according to Wednesday’s statement, is a technology that could allow “renewables to deliver baseload power for less than the cost of fossil fuels 24 hours a day.”

Wednesday’s announcement builds on a recent investment from Mexico's Cemex Ventures, the corporate venture capital unit of building materials giant Cemex, along with a promise of deployment support from Cemex's strategic network. Piconi said in November that the company had sufficient investment from two funding rounds to carry it through initial customer deployments, though he declined to disclose figures.

This is the first energy storage investment for Vision Fund, the $100 billion venture fund set up by SoftBank founder Masayoshi Son. While large by startup standards, it’s in keeping with the capital costs that Energy Vault will face in scaling up its technology to meet its commitments. Those include a 35 megawatt-hour order with Tata Power Company, the energy-producing arm of the Indian industrial conglomerate, first unveiled in November, as well as plans to demonstrate its first storage tower in northern Italy in 2019.

For Vision Fund, it’s also an unusual choice for a storage investment, given that the vast majority of venture capital in the industry today is being directed toward lithium-ion batteries. Lithium-ion batteries are limited in terms of how many hours they can provide cost-effectively, with about 4 hours being seen as the limit today.

The search for long-duration energy storage has driven investment into flow batteries, compressed-air energy storage and variations on gravity-based storage, including a previous startup backed by Gross and Idealab, Energy Cache, whose idea of using a ski lift carrying buckets of gravel up a hill to store energy petered out with a 50-kilowatt pilot project.

The world’s largest battery storage system has already saved customers more than $34 million in its first year of operation and will be expanded by another 50 percent. A growing number of U.S. transit agencies are replacing diesel buses with electric versions, citing the myriad climate, health and cost saving benefits. Ford unveiled its first all-electric SUV, dubbed the “Mustang Mach-E” and capable of traveling more than 300 miles on a single charge. New research highlights the benefits of wind and solar for increased groundwater sustainability. 

The world’s largest battery storage system has proven so effective that the operator plans to make it even bigger

The Hornsdale site, which uses Tesla technology and is located in South Australia, will be expanded by 50 percent to 150 megawatts. In its first year of operation the system has already saved consumers more than $34 million, while stabilizing the grid and avoiding outages. A slew of similar big battery projects are in development in Australia as the country adds more wind and solar capacity. (Bloomberg $)

New Opel Gigafactory in Germany to be largest battery cell producer in Europe

German carmaker Opel, a subsidiary of French PSA, plans to manufacture enough battery cells for half a million e-cars annually in a new factory in western German Kaiserslautern from 2024. Opel revealed details of the planned factory at a press event and said up to 2,000 jobs would be created and two billion euros invested in the facility, which would house three units with a capacity of eight gigawatt hours each and be the largest in Europe so far. Economy minister Peter Altmaier, who attended the event to “highlight the strategic importance” of the plant, said: “There is the prospect that in a few years the production of battery cells, wh ich we in Germany and Europe had thought lost for a long time, will return to this location.” The federal government plans to support the project with “a considerable three-digit-million-euro amount”, he said.

One week ago, France’s head of state Emmanuel Macron and Germany’s research minister Anja Karliczek had already given the official go-ahead for a battery cell pilot production in a factory of the manufacturer Saft in Nersac, southwest France. Another factory is planned in the French region Hauts-de-France. Germany and France have been keen to develop batteries in Europe in order to avoid becoming dependent on Chinese storage systems. The Commission had approved the project under state aid regulations in December 2019. The European Union allows state aid in certain conditions under its rules for Important Projects of Common European Interest (IPCEI).

Carbon Dioxide battery technology represents a huge opportunity not only to vastly improve energy storage and output capacity, but also to capture CO2 straight out of our atmosphere and lock it away. Research is going on all around the world but in the last few weeks a research team from UIC in Illinois has published a paper proving that a Lithium Carbon Dioxide battery can now be recharged successfully and hold far more energy than a traditional battery, and another team working at MIT in Massachusetts has shown us a revolutionary system that significantly improves the efficiency of capturing pure CO2 from ambient air streams. This week we take a look at both of them.

Determining Value in Energy Storage

Comparing total cost of ownership against bare cost of batteries

Written by Brent Perry, CEO, Sterling PBES

SNIPPETS:

Introduction

In the 10 years since I started the first company dedicated to producing specialist lithium ion batteries for the marine industry, there has been a huge uptake from the market. In the very early days, I would tell people that their vessels would be able to run on battery power and they would look at me with disbelief; at that point in time, land based electric propulsion was rare and – in many cases – people’s experiences of it painted a picture of inconsistency and unreliability.

Fast forward and the electric ⚡ cars are here to stay. With few exceptions, western countries are committing to exclusively use electric or hybrid electric vehicles in the medium term. Lithium battery power taken hold in other industries in a similar way, especially commercial shipping. Commercial mariners the world over have fully embraced the use of the technology. They are cheaper and cleaner to run and, most importantly, they outperform conventional vessels with very short-term payback. 

Today, most vessels being built either use energy storage in some way or have the provision for it. They are being built to future proof their investment.

The Apples to Apples comparison

At the beginning of the age of megawatt scale lithium energy systems, it was determined that cost per kilowatt hour (kWh) was a good way to measure the value that lithium could be evaluated. In the years since, there have been many articles, white papers, and countless conference speeches about the goal of reducing the cost of lithium batteries to below $100 USD/kWh. This may be an arbitrary number largely driven by the stationary grid and automotive suppliers, but suppliers were trying to use this measure to identify when lithium would be cheap enough for these industries to be successful. 

The problem with using an arbitrary metric like cost/kWh is that it assumes that all lithium batteries are equal. In the commercial marine space, that assumption is simply not true. The concept of cost/kWh is further complicated by the engineering requirements of marine systems, driven by the flag authorities and classification societies.  Things like safety, reliability and risk a far greater real-world influence on the cost of building batteries for the marine industry and all of the associated systems involved. But, how do we create an “apples for apples” comparison that supports rational commercial decision making?

The Challenge:

Power systems on large vessels are highly complex and it is not easy.  At Sterling PBES, we have taken the decision to measure the cost of an installation and its payback by including all of the elements necessary to offer a complete installed system. Batteries (priced per kWh) are a part of this – but certainly not all of it.  For customers to make a sound decision and understand the overall financial impact, everything needs to be considered.


How do available batteries differ?

There are several versions of battery chemistry available to the battery manufacturers; the dominant chemistries are NMC, Titanate, and LPO or Iron phosphate.  Each of these chemistries have different energy densities (energy density is the amount of energy stored for the volume of the cell. Systems with lower energy density tend to be heavier as well as larger while higher energy density systems are usually lighter). Different battery systems have different lifecycle characteristics, age in different ways, and charge/discharge characteristics.  The marine industry has gravitated towards NMC as a dominant chemistry but even in one chemistry type there are variations in performance existing from one cell manufacturer to the other, principally focussed on whether the cell is a power cell (instant power) or an energy cell (a larger gas tank).  Even the form factor of the cells has a lot to do with the managed risk and performance of a battery. ... ...

30-year batteries

Most commercial vessels built today have a lifespan of around 30 years, but the propulsion equipment onboard will require maintenance or rebuild several times. In fact, a vessel may require several rebuilds of machinery over its lifespan, yet most current battery technology only allows for full replacement.

On this hypothetical 30-year vessel, there will be anywhere from 3-6 battery replacements and subsequent electronic waste entering the recycling stream. Anything that can be done to reduce the environmental impact of the battery should be done.

This happens against the backdrop of increased regulation on the disposal of lithium ion batteries, especially in the EU, which will undoubtedly impact costs for the supplier and subsequently the end user. Sterling PBES’ proprietary CellSwap technology allows the battery to be rebuilt with new cells as required, usually on a 5-year cycle. This allows for a far more accurate prediction of lifespan and required system size as the battery doesn’t need to be oversized to compensate for variables like changes in route, duty, heat or even ownership and maintenance intervals. In fact, a battery that is designed for a 5-year lifespan with CellSwap may be only 30-50% the size of a battery designed for a 10-year life. If that hypothetical 10-year battery is air-cooled, then the size of an alternative liquid cooled system with CellSwap is even smaller. This, in turn, increases value again for the customer.

I think it’s safe to say that the one thing from Tesla people have been waiting for more than any other these past several months is Tesla Battery Day. This is where Tesla will presumably tell us some of its battery secrets, grandiose battery plans, and mind-blowing battery milestones. There are many questions leading into this, and there will probably be more questions on the way out.

Some people say Tesla is a battery company that creates cars, not a car company that produces batteries. I’m not a big fan of calling Tesla a company focused on any one topic. It’s a leading carmaker, battery designer and producer, solar technology company, software developer, and more. Though, it’s safe to say the battery plays a rather special role. It is the heart of an electric car. It is also a key, reality-shifting link in the utility network that enables much more renewable energy. And once upon a time the humble battery had one of the best mascots in TV commercial history.


Getting to the news, it seems Tesla has some new toys coming its way for its battery production games. “Hanwha Group said Sunday that its subsidiary Hanwha Corp. recently signing a supply deal on battery formation equipment with U.S. electric vehicle (EV) giant Tesla,” according to The Korea Times.

“We had a supply deal of battery formation equipment with Tesla,” the official said.

If that reminds you of Alex Voigt’s casting article and makes you think about the physical form of a battery, think again. “Battery formation is the process of initial charging and discharging of battery cells. This process is conducted in the final phase of the battery manufacturing procedure to format and test it before installation. The process demands a high voltage and precise output current to ensure the battery cells will last for the indicated lifetime.” I feel like I should have learned that by now, but I have to admit that a summary of that process has never crossed my desk here at CleanTechnica world headquarters. Though, it is clearly a logical step in the process that you would expect battery producers to follow if you ever thought about that level of detail in the battery production process.

So, where is this tech headed? Seemingly, everywhere. It will reportedly be shipped to Fremont, California (even though Tesla doesn’t produce batteries there), then also Nevada, Germany, and China, the locations of Tesla’s partially built and planned EV-related gigafactories. Perhaps Texas is next on the list.

While the reporting indicates that Tesla is only getting this battery formation equipment, Hanwha Corp. also produces equipment for other stages of the battery production process, in particular the battery assembly stages — “such as notching, stacking, tab welding and pouch forming machines.” No insight is offered on whether Tesla might buy Hanwha equipment for those process as well. If we ever find out, we’ll be sure to share.

Is this information critical to our personal revelations about the meaning of life, the universe, and everything? not particularly, but for us cleantechies, learning about these little details in battery production and the battery market is fun. Throw in Tesla for some extra spice.
