LG Chem: Storage Battery Leader

by Debra Fiakas CFA

The post “Energy Storage Restart,” which was published last week, discussed the efforts by
General Electric (GE: NYSE) to get back into the market for utility-scale energy storage. After some difficulties that required the partial closing of its battery manufacturing plant, GE has got back in the game with new contracts wins. In April 2015, the company won a contract to supply Con Edison Development with an 8-megawatt-hour battery storage system at a solar project in California. GE will be integrating lithium-ion batteries rather than its own battery technology into the project.

Where will GE source the lithium-ion batteries for the California project? So far, spokespersons have been non-committal on the name. Today’s post profiles a company that may not be a likely ‘bedfellow’ for GE, but it is a leader in lithium ion energy storage technology.
LG Chem (051910: KS) is Korea’s largest specialty chemicals company. It’s bread and butter business is supplying petrochemical feedstocks such as ethylene and propylene, aromatics such as benzene and toluene, and specialty polymers such as butadiene-based synthetic rubber. The company reported US$18.7 billion (21.8 trillion Korean won) in sales in the twelve months ending March 2015, providing US$9.48 in earnings per share (11,047.80 Korean won). LG Chem shares the wealth with a dividend that provides a 1.6% yield at the current share price near US$205 per share (238,000 Korean won).

The company got into the battery market thought its long-standing competence in materials sciences. LG Chem began a research and development effort in lithium ion technology in the mid 1990s. According to the Korean Intellectual Property Office, the company is responsible for over two thirds of patents and patent applications related to energy storage systems in Korea. That deep experience has given the company an edge in the automotive battery market. The company’s first product was a lithium-ion battery for a hybrid electric vehicle. In 2015, LG Chem is selling to more auto makers than any other electric vehicle battery producer. The other two leaders, Panasonic and AESC, are heavily dependent upon single customers - Tesla for Panasonic and Nissan for AESC.

In 2010, just five years ago LG Chem brought a residential energy storage unit to the market for households with solar energy installations. The company cuts its teeth in utility-scale energy storage by working with Korea Electric Power on domestic smart grid projects. By 2013, Southern California Edison bought LG Chem storage units for its Tehachapi Wind Energy Project. At the time it was the largest battery energy storage system in North America.
In early 2015, LG Chem recent forged a four-party agreement with Gexpro, Ideal Power and Geli to pursue the energy storage in the North America market. Under the pact, LG Chem will supply its lithium-ion batteries to electrical products distributor GexPro, mostly for residential ‘peak-shift’ applications. Interestingly, Gexpro was founded by General Electric as the old GE Supply and then sold in 2006 to its current parent, Rexel of France. While the partnership is not focused on utility-scale applications, it win a meaningful presence for LG Chem in the fast growing residential U.S. market.

LG Chem may never be a supplier of lithium ion batteries for General Electric. Yet it appears the company has a much if not a greater presence in the North American energy storage market than GE. Shares of LG Chem are trading at 21.5 times trailing earnings. For a company that delivers a 6.0% operating profit margin on mostly commodity products, that is a compelling value. It takes a bit of extra effort to take a position in a stock that is not trading on a U.S. exchange, but it may be well worth it based on LG Chem’s leadership in the battery space.

A Good Year for LG Chem’s Battery Storage Business

The company scored some large battery projects and picked up an important cell deal with Tesla.

by Jason Deign
December 15, 2015


LG Chem is ending the year on a high note after securing two of the world’s largest energy storage projects and leading an electric-vehicle battery manufacturer survey.

In late November, LG Chem won contracts to install a 50-megawatt-hour storage facility in South Korea and a 140-megawatt-hour project in Germany. That same week, the firm was named the world’s top electric-vehicle battery maker in terms of strategy and execution by Navigant Research.

The Navigant Leaderboard Report, which looked at companies making lithium-ion batteries for transportation, did not factor in current market share. Panasonic currently leads the market, but the company is under threat from LG Chem, according to an August report from Lux Research.

Navigant examined the business strategies of eight leading lithium-ion battery manufacturers active in the light-duty electric-vehicle market. It put LG Chem ahead of Panasonic based on an analysis of twelve criteria, which included vision, go-to-market strategy, partners, technology, geographic reach, and sales, marketing and distribution.

Samsung SDI came third in the ranking, followed by AESC, Johnson Controls, BYD and A123, which were all listed as "contenders" rather than "leaders."

Last month, Tesla confirmed it was switching from Panasonic -- its usual cell vendor -- to LG Chem products in its Roadster battery pack upgrades. The news was a blow for Panasonic, which has built its electric-vehicle battery business largely on the back of Tesla sales.

LG Chem is also becoming a supplier of choice for leading auto brands such as General Motors, Renault and Daimler.

LG Chem’s grid storage business was also bolstered with two major wins announced at the end of last month.

The 50-megawatt-hour South Korean battery, which will be paired with a wind farm, is being touted as the largest of its kind. The project will be built on behalf of GS E&R, a privately owned South Korean developer. GS E&R has been operating the wind farm since September, and the storage facility will help it smooth out intermittency from the turbines.

The GS E&R project was announced a day after LG Chem unveiled a deal to supply 90 megawatts and 140 megawatt-hours of storage to STEAG, a German utility.

The battery storage will be spread across six power plants, in Herne, Lünen, Duisburg-Walsum, Bexbach, Fenne and Weiher, between mid-2016 and the beginning of 2017. The batteries will be used for frequency regulation.

The STEAG win follows other recent grid-scale deployments, such as a 2-megawatt system for Duke Energy and a 1-megawatt project for OCI Solar Power in the U.S.

LG Chem claims to have won 100 megawatt-hours' worth of orders for residential energy storage in 2015 and is also eyeing opportunities in the commercial and industrial sectors.

Philip Hiersemenzel, a spokesperson for Younicos, which developed the OCI Solar Power project, said he expected the battery maker to announce further projects in South Korea following the GS E&R win.

“[South] Korea is their home market, and it’s effectively an island,” he said. “They are also open to new technologies, have great renewable energy potential and are driven by their car industry. I think we’ll see a lot more happening there in future.”

AES Energy Storage Reaches Supply Agreement with LG Chem

December 16, 2015
By Renewable Energy World Editors


AES Energy Storage said on Dec. 15 that it has reached a multi-year agreement with LC Chem for the supply of batteries for AES’ Advancion grid-scale energy storage solution.

According to AES, the agreement provides access to several of LG Chem’s battery modules to meet the needs of Advancion installations currently under construction and allows AES to purchase additional batteries to meet the growth for future Advancion system sales.

AES previously announced installations for various customers in six countries totaling 384 MW in operation, construction, or late stage development. Navigant Research projects that more than 11 GW of energy storage capacity will be installed annually by 2020 across 22 countries.

“We are excited to provide utilities, developers, and businesses access to high quality batteries at the best prices as part of the complete Advancion grid storage solution,” John Zahurancik, President of AES Energy Storage, said in a statement. “LG Chem is one of our most trusted battery partners and this agreement provides a new scale of activity to serve announced projects as well as installations under development by our utility partners.”

AES said that the supply agreement covers battery modules with configurations ranging from 30 minutes to four hours of discharge duration. AES and LG Chem have also agreed to collaborate on joint development initiatives that will ensure continued competitiveness of the Advancion product in meeting the requirements of utilities and system operators.

In 2014, LG Chem was the first of several battery manufacturers to complete the Advancion Certification process and become a qualified supplier of batteries for Advancion 4. Subsequently, LG Chem was selected to provide batteries for three large-scale Advancion arrays, including the Warrior Run Energy Storage Array that was officially opened on Nov. 13 in Cumberland, Md.

Advancion 4 is AES’ fourth generation integrated energy storage solution, which the company said incorporates insights from lessons learned from more than eight years of real world operations of large-scale, grid-connected battery systems built to serve the needs of a long-term asset owner.

"This new storage unit is a big step forward." Interview with Santiago Senn, director of LG Chem Europe

http://www.pveurope.eu/News/Energy-Storage/This-new-storage-…

4/12/16, 9:13 AM -

Which market sector is showing the most promising developments in the storage sector? In an interview with expert Santiago Senn, we discussed innovation in storage systems, markets and distribution.


At the Intersolar in Munich, you introduced the Resu 6.4 EX, a new storage system. How have sales been progressing?

We had marketed the predecessor model Resu 5.0 in Europe the previous year. This new storage unit is a big step forward, that much is clear from the sales figures. The Resu 6.4 EX has a capacity of 6.4 kilowatt hours and can be extended using two battery packs of 3.2 kilowatt hours each, resulting in a maximum capacity of 12.8 kilowatt hours. Nevertheless, the unit is very compact and, because the basic version only weighs 60 kilograms, it is very easy to install. Any technician could do that. Even though the battery capacity really is not that small, the unit looks more like the case of a desktop computer.

Do you distribute directly to installation companies?

No, we exclusively go through retailers and other distributors. In Germany, distribution goes via wholesalers such as BayWa, EWS, ESC, Viessmann, Krannich, Nedap, Memodo or IBC Solar. In the UK, we also cooperate with suppliers of ready-for-use applications like some project developers and EPC companies. However, the UK market for storage is no comparison to what is happening in Germany. This is where the main focus of our business lies, but Italy is also slowly getting started.

How is the German market developing?

It has to be said that the market is not yet established. The relative growth from last year is strong, but in absolute figures it is not so large. But we do see a steeply rising trend. Unfortunately, this strongly depends on the developments in the PV market, which in Germany is currently languishing. We are a bit worried about that.

And in Austria or Switzerland?

We are not really seeing a market for storage in Switzerland. Not yet. And Austria will also take a little time. I think that the market in the UK and Italy will get going first. In Germany we are at a point where PV without storage makes very little sense, at least if we are talking about newly installed capacity. As we see it, there also is a market in retrofitting existing installations.

To make that possible, the storage unit would need to be compatible with as many inverters as possible. How far are you on that?

So far, our battery has been running on SMA and with Nedap’s Power Router. But we have recently successfully tested new inverters for compatibility. Among those are the products by Sungrow, Solax, Ingeteam, Victron Energy and others. We are also looking into offering more battery capacities, but that has not yet definitely been decided.

The situation in the stationary storage sector is like that in PV: The market grows if prices go down. What is your assessment of how the price of storage is going to develop?

Our first priority is bringing down the costs per kilowatt hour. So far we have managed to achieve year-on-year price reductions by double-digit percentages. The rising demand for e-mobility has clearly worked in our favour. This sector is currently going through the roof. Given certain alterations in cell chemistry, our cells can equally well be fitted to cars or storage units. They are coiled pouch cells which are very versatile in their application. We keep on working on extending the capacity of our cells. The next generation will have twice the energy density of the current one, which is a real technological leap, and that will affect prices.

Like Panasonic or Tesla, LG Chem also offers cylindrical power cells. What application were these designed for?

This is our segment for mobile applications. These kinds of cells are used in smart phones or laptop computers. Our production capacity for mobile products this year is about nine gigawatt hours. We are working towards increasing that. When it comes to cells for automotive and stationary applications, we currently build seven gigawatt hours. Our plans for capacity expansion in this area are much more aggressive. Capacity expansion alone will bring about greater leeway as far as costs are concerned.

Where are you producing the storage units?

Our factory is in South Korea and LG Chem will be among a few manufacturers that will eventually dominate the market in lithium cells – and mostly because the price essentially hinges on the ability to innovate and produce greater capacity. To have a chance in this market, you need to have international presence and have a strong brand behind you. LG is such a brand. This is also demonstrated by our solar panels, which are produced by our sister company LG Electronics. In the US we have a small factory that produces specialised battery cells for electric vehicles for the US market.

The pressure to reduce costs is mounting, not least as a result of Tesla’s activities in the US. In April 2015, Elon Musk promised to offer lithium cells at 250 US dollars per kilowatt hour. Can you keep up with that?

Let me put it this way: Tesla’s announcement just before the Intersolar has been a boon to our sector. It has also been good for sales, we all profited from the media storm. For the seven kilowatt hour Power Wall, Tesla was promising a gross wholesale price of 3,615 euros. Yes, we can keep up with that. Please understand that I cannot state concrete prices, and that our road map actually includes further price reductions. Nonetheless, I believe that the Power Wall will give fresh momentum to the market – not just in Europe.

Which market sector is showing the most promising developments or might be the one to really take off in the next few months?

I think that storage will allow small businesses and smaller industry to save a lot of money. They often pay the utilities’ commercial tariffs and have no access to tariffs for large-scale industry. That can be worthwhile, some day. It may take a little time, but we will keep an eye on the segment of storage around 20 kilowatt hours. Using racks, our batteries can be extended indefinitely, no problem. And we are already noticing that large-scale industrial storage is becoming increasingly important.

The mega battery in Feldheim has been quite the coup for you. You were able to install ten megawatts at a stroke last summer, i.e. a thousand ten-kilowatt hour storage units. Will such giant units become commonplace?

I would not say that. But such container solutions for megawatt-scale storage will be a new and interesting proposition particularly for municipal utilities. This is true even in spite of the fact that the Federal Network Agency has recently added more stringent requirements for large-scale storage to the primary control of the grid. But commercial-scale storage can still be feasible. The load-balancing power station in Feldheim is the largest stationary storage unit in Europe, and now has a medium-voltage link to a wind farm. We have since had a number of inquiries from municipal and regional utilities wanting to set up battery units. We have commercial and industrial projects in Germany, Italy, Switzerland, France and the UK.

What will the prices for storage be like in five years?

I would estimate about half of what they are today. Because in five years there will not be a single car manufacturer that is not also involved in e-mobility. Many fully electric vehicles will run on our energy cells, while hybrid cars will include our power cells. We are currently in negotiations with most major car manufacturers. At the IAA in September, Audi presented their new concept car – their response to Tesla. And we have a hand in that.

And in PV?

Of course we are hoping that the German market will recover. The current hard times are only a short-term slump. Electricity storage for private households and industry will spread from the German into other markets, we can already see this taking shape. PV without storage will then no longer make sense. Even large solar installations will be built in combination with large-scale storage units, in order to take advantage of innovative business models. However, in the long run I can only see a few manufacturers of storage units being in with a chance in such fast-paced developments. The market has to be able to function without support or subsidies. And that is not too far off. We are self-evidently making rapid progress in that direction.

Sunrun and LG Chem partner on solar-plus-storage

By Danielle Ola Oct 27, 2016


Residential installer Sunrun has teamed up with LG Chem, a Korean battery manufacturer, to offer solar-plus-storage systems in the US.

LG Chem will supply its lithium-ion RESU batteries for Sunrun’s BrightBox solar generation systems, which gives homeowners the ability to store solar energy generated during the day for use in the evening, offering significant savings on electricity bills.

“The energy storage market is advancing at a breakneck pace. At Sunrun, we are enabling a home energy management service that integrates rooftop solar generation with onsite energy storage to offer greater energy choice and savings to our customers while helping to modernize the grid,” said chief marketing officer Michael Grasso, in a statement. “We’re thrilled to offer LG Chem’s best-in-class battery technology to homeowners. The partnership with LG Chem supports our financing advantage, enabling our customers to install solar plus energy storage for little to no money down.”

San Francisco-based Sunrun started offering BrightBox this year in Hawaii, using Tesla batteries. The company has plans to expand the system to California in 2017. According to company co-founder Ed Fenster, the company is waiting to see how California regulators adjust electricity rates next year, and peak-hour prices in particular.

In future, BrightBox will allow consumers to adopt a time-of-use (TOU) rate model to time shift when solar energy is used to minimise peak prices. TOU is expected to be the most-used rate design in California by 2019.

The partnership expands the application of LG Chem’s energy storage systems, which are normally deployed in the electric vehicle market, to the consumer residential market, giving more individuals the chance to access clean, affordable energy.

On the residential scene, the pairing of batteries with solar is often considered too expensive a proposition. However, solar-plus-storage makes sense in Hawaii where electricity prices are particularly high. Systems are typically leased to avoid upfront costs. Since Sunrun plans to own the BrightBox systems, it could potentially sell electricity from the batteries to the utilities during peak hours, allowing Sunrun to offer the system to its customers for a lower cost than would otherwise be possible.

Energy storage: LG Chem Europe surprised by high demand

7/4/17, 11:00 AM -

http://www.pveurope.eu/News/Energy-Storage/Energy-storage-LG…

For six months he has been Head of Sales in Europe for Korean battery manufacturer LG Chem.

At Intersolar in Munich the supplier has won second EES Award for its new battery module.

Stefan Krokowski talks about innovations, products and emerging markets in domestic and commercial energy storage:


You joined LG Chem in Sulzbach early this year and thus were not with the company in 2016. Nevertheless, can you give us an outline of the past year?

...Stefan Krokowski: I am happy to try. At the Intersolar 2016, we presented our new Resu series and it was a great success. Demand has been extraordinarily good. And we were pleased to notice that our brand is gaining in importance in the storage market. Yes, 2016 happened without me, but it went pretty good. We sold more than 5,000 Resu units in Europe.


How did 2017 start, now that you are involved and giving it your all?

..The current year will also be a very good one. We are noticing a trend among our distributors that shows us that the market will be very active this year.


There has been high demand for Resu energy storage systems and supply periods are fairly long. How are you dealing with this problem?

...To be honest, we were quite overwhelmed by the success of the Resu series. As far as our low-voltage battery of 48 volts is concerned, we have now gotten to grips with the supply situation. We have worked out a rolling forecast process with our distributors, which allows us to keep track of the expected volumes to be supplied.


And for the high-voltage version?

...The launch has been delayed a little bit, also because we were surprised by the high demand. Also, other providers of DC batteries have switched to AC units, which has generated further demand. So we first need to step up production, but that issue will be solved within the next few months.


Your batteries are imported directly from LG Chem in Korea. Would it not make sense to build a factory in Europe? Poland is being discussed as a location ...

...True: Shipping by sea takes eight weeks. Also true: We are starting up production in Poland. But this is more to meet the needs of the automotive sector, which usually runs on a just-in-time basis. This requirement is not there for stationary storage batteries.


Which markets have so far been important to you in the energy storage segment?

...In Europe, that is clearly and most of all the German market. But we are also seeing rising demand in the UK and France. We are taking a keen interest in the announcement by the Swedish government that they will subsidise energy storage batteries by up to 60 percent of the investment costs; Sweden wants to rapidly transform their energy supply system. The low countries are also seeing rising demand: Net metering should be a hindrance to storage, but the fact that we are seeing a rise in demand anyway, shows that people are eager to invest in their independence. So this is not only a matter of economic criteria, but, just like when buying a car, emotional and psychological factors also come into play.


How will the prices for energy storage systems develop?

...In the medium term, prices will fall, but this will not happen as fast and abruptly as with photovoltaics. For one thing, the euro is currently very weak. That is problematic for providers that sell their cells or batteries into Europe from overseas. For us, the depreciation of the euro against the Korean won makes any reduction in prices unlikely. Furthermore, the prices for raw materials have gone up.


What raw materials are we talking about here?

...Cobalt most of all. Prices are driven up by a high demand from a number of sectors. And we may also be witnessing the result of speculative commodity futures trading. But I am expecting prices to stabilise in the medium term.


How will the energy density of lithium cells progress?

...This is where we have real leverage for lowering prices: If cells become more energy-dense, that can bring down the price per kilowatt hour. There is no way for me to quantify that, but of course we will continue to work on making our cells ever more efficient.


70 to 80 percent of the production costs of storage batteries come from the lithium cells. How much leeway do you see in what remains, i.e. in the housings and the electronics?

...To be honest, I see very little leeway there. This is a block of fixed costs and there is not much that can be done about them. No matter what, you need both, the solid aluminium housing and a battery management system. These have to be developed and assembled, regardless whether you end up with a storage unit of three or 20 kilowatt hours of capacity. Because the cost for lithium cells will eventually come down, we will see larger storage systems. And this will reduce the proportion of fixed costs in relation to the cells and battery modules.


We are already seeing that in the market: With prices for storage coming down, people are buying larger systems – because they want to be more self-sufficient.

...Even if the larger battery is not necessarily more economical for their solar array and the consumption patterns of their house. It is clearly all about independence. That is what I was talking about when I made the comparison to buying a car. One more argument in favour of larger battery systems is that they go through the retailers’ value chains just like the smaller units. And it does not take any more time for the technician to connect them.


So far, LG Chem has very little presence in the market for commercial storage. Why is that?

...It is possible to combine two of our Resu 10s, which gives you 20 kilowatt hours. Our next larger system then are megawatt-scale units that we deliver the cells for. We do not build such storage solutions ourselves, but in collaboration with our systems integrators. In the commercial range of, say, several hundred kilowatt hours we are quite involved as a supplier of cells, although we leave the integration of the battery systems to our partners.


Shall we take a look at what next year will bring?

...Sure. I see a dramatic paradigm shift ahead for the energy supply sector, in which storage batteries will play an essential role. They are capable of taking in and giving off electricity at any given place and time and at varying prices. And storage is the catalyst for this development, which is spurred on by PV and other forms of decentralised generation. A key driver of this development probably is electric mobility, i.e. mobile storage.

http://www.pveurope.eu/News/Energy-Storage/Energy-storage-A-…

"...

This year, they showed a new battery module that is designed as a stand-alone system. This DC battery stores 6.5 kilowatt hours of solar electricity, and up to ten of such modules can be combined to form a battery of 65 kilowatt hours.

And although the same JH3 cell as for the Resu units is at the heart of this new system, it is clever for its high degree of standardisation as well as its control electronics: multiple modules are wired up according to the master-slave principle and connected to the inverter or charging controllers, which then control them directly.


Quickly build up large storage units

Thus: Using these battery modules, any system integrator can very quickly put together large-scale storage units and adapt them to the needs of his customers. Even though LG Chem do not intend to get into the market for commercial storage, as they did by introducing their Resu units to the market for private end customers last year, their SBM (stand-alone battery module) should soon allow them to become the leading supplier to providers of commercial storage. Because the JH3 cell, which is constantly being enhanced, has a great energy density, has an application in the automotive sector most of all. The next generation – JH4 – is soon to follow and it is to be expected that the energy density will again rise sharply.

The cells, both within the battery module and among the modules, are controlled in such a way to enhance service life. In case of weaknesses or defects, the affected battery module can be removed from the battery rack and replaced without difficulties.


Economies of scale

This battery module will be very soon be manufactured in large volumes. This will allow LG Chem to massively reduce the price per unit in order to make the batteries more inexpensive. This is hard to achieve with individual fixed-output batteries as in the Resu series. And even though LG Chem were able to sell 5,000 units last year, achieving really high volumes is only possible if all storage units are based on a standard and easily integrated battery module. The Chinese battery manufacturer BYD, Panasonic from Japan and Samsung, from Korea like LG Chem, are also following this path.

The voltage level of the battery modules is at 51.8 volts, they run on 42 to 58.8 volts. Because of their high energy density of 227 watt hours per litre, the individual SBMs are very compact and easy to handle. They are controlled by a CAN 2.0B or a Modbus 485. Another 3.3 kilowatt hour variant still manages to achieve an energy density of 197 watt hours per litre.


Refining cells at a higher level

That way, it will in the future make less sense for storage suppliers to order separate cells from LG Chem: They will buy in complete battery modules and integrate them, thereby making the in-house manufacture of modules redundant.

LG Chem will thus take over that part of the value chain and refine their cells at a higher level. The prospects are enormous: The lithium ion storage market could expand to 16 gigawatt hours by 2020, compared to three gigawatt hours in 2016.

LG Chem demontrated their desire to take centre stage in this segment by the quality of their submission to the EES Award: Few of the submitted proposals could match theirs in terms of scale and value when it came to technical details on innovation, test reports and certificates.
