What are the main drivers of growth in batteries?
What’s the battery growth forecast to 2030?
What are the potential bottlenecks for energy storage and battery markets?
The battery market is a critical piece of our global energy future, and it’s growing at an unprecedented rate. The electrification of the transportation industry, the use of battery systems to provide energy storage and demand management for the grid, and the batterification of many devices continues to spur this industry’s growth. These developments are already affecting:
As batteries offer potential solutions to the challenges of legacy electric grids, it’s important to use market forecasting and intelligence to make sound planning decisions.
Sam Jaffe, vice president of Battery Storage Solutions at ESource, explained in our webinar Battery market forecast to 2030 that the presence of a Li-ion battery changes not just the essence of the product it’s added to but the entire market for it. Jaffe says that customer-sited solar plus storage and a battery’s ability to balance to balance generation with sophisticated load control will be disruptive forces on the current utility model.

Growth in the battery industry is a function of price. As the scale of production increases, prices come down. Figure1 forecasts the decrease in price of an automotive cell over the next decade. The price per kWh moved from $132 per kWh in 2018 to a high of $161 in 2021. But from 2022 to 2030 the price will decline to an estimated $80 per kWh. Factors like material supply and charge-discharge strategies will have an influence on market growth.
Recycled Li-ion cells are less expensive than newly manufactured cells, and they’ll begin to substantially affect the supply chain around 2027. We expect reused Li-ion to represent 11% of the supply chain by 2030.
The idea of batteries cycling twice per day (or double dipping) will affect efficiencies and the overall number of batteries installed on the grid. Figure2 shows excess renewables generation during two distinct times of the day: overnight during wind overproduction and midday during solar overproduction. Meanwhile, there is an excess of demand during the early morning hours and in the evening. At these times, batteries can discharge. A battery that has four hours of energy capacity can charge and discharge twice, providing eight hours of discharged energy when it’s needed most. This won’t affect the cycle life of the battery because the actual charging regime will be relatively gentle.
We’re in the beginning stages of integrating batteries at various capacities onto the grid. Globally in 2021, the grid had 30 gigawatt-hours (GWh) of battery storage installed. We expect that number to grow to 400 GWh by 2030. This has many implications for utilities, battery storage investors, and large commercial energy users:
Our forecast predicts Li-ion manufacturing capacity to stay above global demand through 2030. Figure3 shows our forecast model of manufacturing capacity. We assume a healthy dose of skepticism in our model based on thousands of data points. We expect a sixfold increase in manufacturing capacity between now and 2030, an increase from 510 GWh manufactured today to over 3,100 GWh by 2030.
We tracked 30 battery markets in major regions and found that in 2022 the world will consume or demand 420 GWh of Li-ion batteries for all applications. By 2030 that will rise to 2,722 GWh. Stationary battery storage isn’t likely to account for more than 15% of all battery energy capacity. Understanding the trends and dynamics of other battery markets, ranging from power tools to e-scooters to automobiles, will allow stationary storage battery consumers like utilities and independent power producers to hedge against unanticipated pricing and supply shocks in the future.
Of all the commodities that go into the battery supply chain, lithium is the most critical possible bottleneck. To meet anticipated demand, lithium producers will need to build new extraction and processing facilities and strongly consider geographic constraints. Other battery materials with critical constraints will involve nickel, cobalt, and copper foil.
Inflation will also affect supply-chain constraints. In 2021, most material inputs had increased in price. Even industrial commodities like PVDF (polyvinylidene fluoride, a polymer binder used during the manufacturing process) and phosphoric acid (used in some battery formulas) had seen price increases of 30%–50%. Lithium has seen the highest price spikes. Spot pricing for lithium carbonate, the most-used form of lithium feedstock for batteries, increased by 400% in the past 18 months.
When a stationary battery sits unused, it’s not earning money for you. Batteries need to be charged or discharged as often as possible to earn revenue. To keep up, the industry will need to develop higher-quality batteries and more-advanced technologies.
An EV battery cell is different, as it’s temperature regulated, safely enclosed, and sitting 90% of the time. Even with these differences, we expect the $100-per-kWh pricing to occur around the same time for stationary storage and EVs (in 2025). Effective energy storage programs can help you and the customer make the most of batteries.
Increasing scale in battery manufacturing is the only way to produce a decent margin. Operating margins are small and barriers to entry are large, which cause oligopolies. Today, a few companies in China make most of the batteries. Even as manufacturing ability increases in Europe and the US and Canada, we’ll continue to see just a handful of companies dominating the market.
As we electrify transportation, vehicle charging becomes a challenge. A light-duty EV can pull 15 kW on Level2 chargers. Fast-charging commercial trucks draw as much as 1 megawatt (MW). Newly built commercial charging stations draw as much as 100 MW at full capacity. Many large battery packs charged at the same time can severely strain the grid. As a result, utilities need to carefully design charging stations. We offer some solutions in the report Building your EV charger asset management plan.
