Over the last decade a surge in lithium-ion battery production has led to an 85% decline in prices, making electric vehicles and energy storage commercially viable for the first time in history.
 
Batteries hold the key to transitioning away from fossil fuel dependence, and are set to play a greater role in the coming decade.
 
UBS estimates that over the next ten years the energy storage market in the United States could grow to as much as $426 billion, and there are many ways to buy into the surge, including chemical companies, battery cell makers, car companies, solar companies and utility companies.
 
Capturing the massive economic opportunity underlying the shift to controls and battery-based energy systems requires that planners, policymakers, 
regulators, and investors take an ecosystem approach to developing these markets,” sustainability-focused research firm Rocky Mountain Institute said recently.
What a difference a decade can make. In 2010, batteries powered our phones and computers. By the end of the decade, they are starting to power our cars and houses too.
 
Over the last ten years, a surge in lithium-ion battery production drove down prices to the point that — for the first time in history — electric vehicles became commercially viable from the standpoint of both cost and performance. The next step, and what will define the next decade, is utility-scale storage.
 
As the immediacy of the climate crisis becomes ever more apparent, batteries hold the key to transitioning to a renewable-fueled world. Solar and wind are playing a greater role in power generation, but without effective energy storage techniques, natural gas and coal are needed for times when the sun isn’t shining or the wind isn’t howling. And so large scale storage is instrumental if society is to shift away from a world dependent on fossil-fuel.
 
UBS estimates that over the next decade energy storage costs will fall between 66% and 80%, and that the market will grow to as much as $426 billion worldwide. Along the way entire ecosystems will grow and develop to support a new age of battery-powered electricity, and the effects will be felt throughout society.
 
Changing electrical grid
If electric vehicles grow faster than expected, peak oil demand could be reached sooner than expected, for instance, while more green-generated power will alter the makeup of the electricity grid.
 
In a recent note to clients, Cowen analysts said that the grid will “see more changes over the next ten years than it has in the prior 100.”
 
The growing energy storage market offers no shortage of investing opportunities, especially as government subsidies and regulations assist the move towards clean energy. But like other highly competitive markets — such as the semiconductor space in the 1990s — the battery space hasn’t always provided the best return for investors. A number of battery companies have gone bankrupt, underlining the fact that a society-altering product might not reward shareholders.
 
“Eventually this will come down to some industry leaders who make some money,” JMP Securities’ Joe Osha said. “I think all these companies are going to do a good job of delivering declining prices for [electric vehicle] manufacturers over the course of the next 5-10 years. I am not so sure that they are going to generate great stockholder returns in the process.”
 
That said, while it might be tricky to invest in pure-play battery companies, there are opportunities to target companies that stand to benefit from the shift to a low-carbon world. For example, Sunrun is the largest residential solar company in the United States, while NextEra Energy is one of the country’s largest renewable power companies and is currently building out its utility-scale storage.
 
As scientists alter the chemical makeup of batteries and companies make bets on what could be the next breakthrough technology, Dan Goldman, founder at clean tech-focused venture capital firm Clean Energy Ventures, said that areas like innovative battery management systems are a good bet for investors since they can work with any battery technology.
 
“Capturing the massive economic opportunity underlying the shift to controls and battery-based energy systems” requires that not only planners, policymakers and regulators but investors “take an ecosystem approach to developing these markets,” researchers from Rocky Mountain Institute wrote in Breakthrough Batteries: Powering the Era of Clean Electrification.
 
Batteries: the new star of science
Battery technology in its simplest form dates back more than two centuries. The word itself is an umbrella term since batteries come in all shapes and sizes: lead-acid, nickel-iron, nickel-cadmium, nickel-metal hydride, etc.
 
Lithium-ion batteries — which itself can be a catchall term — were first developed in the 1970s, and first commercialized by Sony in 1991 for the company’s handheld video recorder. They’re now found in everything from iPhones to medical devices to planes to the international space station.
 
Perhaps the greatest indication of the role these batteries have played in modern society is that this year’s Nobel Prize in Chemistry was awarded to the three scientists who developed the lithium-ion battery.
 
“Over the past decades, this development [lithium-ion batteries] has progressed rapidly, and we can expect many more important discoveries to come in battery technology,” the Royal Swedish Academy of Sciences said in October. “These future breakthroughs will undoubtedly lead to further improvements in our lives, not only for our convenience, but also with respect to global and local environments and, ultimately, the sustainability of our entire planet.”
 
Electric vehicles: going the distance
Tesla was the first car company to commercialize a battery-powered electric vehicle when it unveiled the Roadster in 2008. Automakers had previously tinkered with hybrid models, but they were generally uninterested in fully electric cars, given the high cost of production.
 
But consumer tastes have shifted over the last decade, and as regulatory oversight increases — especially in Europe — automakers have had to keep up.
 
Virtually all automakers now offer or plan to offer fully electric — or, at the very least — hybrid car models. In November Ford unveiled its all-electric Mustang Mach-E, which is part of the company’s $11 billion plan to develop 40 all-electric and hybrid models by 2022, and in March Volkswagen increased its electric vehicle goal to 70 new models by 2028, up from a prior target of 50.
 
Battery pack prices for electric vehicles are typically looked at in cost per kilowatt hour. Over the last ten years prices have fallen as production has reached economy of scale. They now cost around $156 per kilowatt-hour, according to BloombergNEF, which is an 85% decline from 2010′s $1,100 plus/kWh cost. And continued production and improving efficiencies are set to make prices drop below the $100/kWh price by 2024, BloombergNEF found, which is significant since that’s the industry consensus for when electric vehicles will reach price parity with internal combustion engine vehicles.
 
“Although the concept of electric vehicles is not new, what is different in this automotive cycle is the availability of reliable and low-cost batteries that possess excellent energy and power capabilities in a practical form factor,” Cowen analyst Jeffrey Osborne said in a recent note to clients.
 
Worldwide sales of plug-in electric vehicles — which includes battery-powered electric vehicles and plug-in hybrid electric vehicles — hit 1.98 million in 2018, according to the International Energy Agency, bringing the total number of electric vehicles on the road to more than 5.1 million. That’s still a very small portion of the 1 billion-plus cars on the road today, but the number is expected to keep growing. BloombergNEF predicts that by 2040 57% of new passenger car sales will be electric, which would bring the total electric fleet to 30%.
 
Tesla is currently the world’s largest manufacturer of electric vehicles, and while it has yet to turn a profit on an annual basis, it has posted a profit on a quarterly basis, including in the most recent quarter. The company has proved to be somewhat polarizing from an investing angle, given the frequent delivery target misses and the sometimes erratic behavior of CEO Elon Musk.
 
But the company has been successful in getting the price of its battery pack down. This is in part due to Tesla’s gigafactory in Sparks, Nevada which operates close to peak efficiency, and also because the company’s residential and utility storage options help to spread the fixed costs of battery production. The company has also benefited from government subsidies and streamlined operations at its gigafactory.
