Visualizing Where Clean Energy Technologies Are Manufactured

When looking at where clean energy technologies and their components are made, one thing is very clear: China dominates the industry.

The country, along with the rest of the Asia Pacific region, accounts for approximately 75% of global manufacturing capacity across seven clean energy technologies.

Based on the IEA’s 2023 Energy Technology Perspectives report, the visualization above breaks down global manufacturing capacity by region for mass-manufactured clean energy technologies, including onshore and offshore wind, solar photovoltaic (PV) systems, electric vehicles (EVs), fuel cell trucks, heat pumps, and electrolyzers.

The State of Global Manufacturing Capacity

Manufacturing capacity refers to the maximum amount of goods or products a facility can produce within a specific period. It is determined by several factors, including:

• The size of the manufacturing facility
• The number of machines or production lines available
• The skill level of the workforce
• The availability of raw materials

According to the IEA, the global manufacturing capacity for clean energy technologies may periodically exceed short-term production needs. Currently this is true especially for EV batteries, fuel cell trucks, and electrolyzers. For example, while only 900 fuel cell trucks were sold globally in 2021, the aggregate self-reported capacity by manufacturers was 14,000 trucks.

With that said, there still needs to be a significant increase in manufacturing capacity in the coming decades if demand aligns with the IEA’s 2050 net-zero emissions scenario. Such developments require investments in new equipment and technology, developing the clean energy workforce, access to raw and refined materials, and optimizing production processes to improve efficiency.

What Gives China the Advantage?

Of the above clean energy technologies and their components, China averages 65% of global manufacturing capacity. For certain components, like solar PV wafers, this percentage is as high as 96%.

Here’s a breakdown of China’s manufacturing capacity per clean energy technology.

So, what gives China this advantage in the clean energy technology sector? According to the IEA report, the answer lies in a combination of factors:

• Low manufacturing costs
• A dominance in clean energy metal processing, namely cobalt, lithium, and rare earth metals
• Sustained policy support and investment

The mixture of these factors has allowed China to capture a significant share of the global market for clean technologies while driving down the cost of clean energy worldwide.

As the market for low-emission solutions expands, China’s dominance in the sector will likely continue in the coming years and have notable implications for the global energy and emission landscape.

Visualizing China’s Dominance in Battery Manufacturing

With the world gearing up for the electric vehicle era, battery manufacturing has become a priority for many nations, including the United States.

However, having entered the race for batteries early, China is far and away in the lead.

Using the data and projections behind BloombergNEF’s lithium-ion supply chain rankings, this infographic visualizes battery manufacturing capacity by country in 2022 and 2027p, highlighting the extent of China’s battery dominance.

Battery Manufacturing Capacity by Country in 2022

In 2022, China had more battery production capacity than the rest of the world combined.

With nearly 900 gigawatt-hours of manufacturing capacity or 77% of the global total, China is home to six of the world’s 10 biggest battery makers. Behind China’s battery dominance is its vertical integration across the rest of the EV supply chain, from mining the metals to producing the EVs. It’s also the largest EV market, accounting for 52% of global sales in 2021.

Poland ranks second with less than one-tenth of China’s capacity. In addition, it hosts LG Energy Solution’s Wroclaw gigafactory, the largest of its kind in Europe and one of the largest in the world. Overall, European countries (including non-EU members) made up just 14% of global battery manufacturing capacity in 2022.

Although it lives in China’s shadow when it comes to batteries, the U.S. is also among the world’s lithium-ion powerhouses. As of 2022, it had eight major operational battery factories, concentrated in the Midwest and the South.

China’s Near-Monopoly Continues Through 2027

Global lithium-ion manufacturing capacity is projected to increase eightfold in the next five years. Here are the top 10 countries by projected battery production capacity in 2027:

China’s well-established advantage is set to continue through 2027, with 69% of the world’s battery manufacturing capacity.

Meanwhile, the U.S. is projected to increase its capacity by more than 10-fold in the next five years. EV tax credits in the Inflation Reduction Act are likely to incentivize battery manufacturing by rewarding EVs made with domestic materials. Alongside Ford and General Motors, Asian companies including Toyota, SK Innovation, and LG Energy Solution have all announced investments in U.S. battery manufacturing in recent months.

Europe will host six of the projected top 10 countries for battery production in 2027. Europe’s current and future battery plants come from a mix of domestic and foreign firms, including Germany’s Volkswagen, China’s CATL, and South Korea’s SK Innovation.

Can Countries Cut Ties With China?

Regardless of the growth in North America and Europe, China’s dominance is unmatched.

Battery manufacturing is just one piece of the puzzle, albeit a major one. Most of the parts and metals that make up a battery—like battery-grade lithium, electrolytes, separators, cathodes, and anodes—are primarily made in China.

Therefore, combating China’s dominance will be expensive. According to Bloomberg, the U.S. and Europe will have to invest $87 billion and $102 billion, respectively, to meet domestic battery demand with fully local supply chains by 2030.
