The Battery Industry’s Exponential Growth and Sustainability Imperative
The global demand for batteries is skyrocketing, driven largely by the urgent need to reduce climate change through the electrification of mobility and the broader energy transition. Just as analysts often underestimate the growth of renewable energy, battery demand forecasts tend to fall short, regularly requiring upward revisions.
A 2022 analysis by McKinsey’s Battery Insights team projects that the entire lithium-ion (Li-ion) battery value chain, from mining to recycling, could grow by over 30% annually from 2022 to 2030, reaching a market size of more than $400 billion and 4.7 TWh. This staggering growth will be driven primarily by the rapid adoption of electric vehicles (EVs), which are expected to account for around 4,300 GWh of demand by 2030. Additionally, battery energy storage systems (BESS) will see a compound annual growth rate of 30%, rivaling the total GWh required for all battery applications today.
While this exponential battery growth will bring numerous environmental and social benefits, it also presents significant challenges that the industry must address head-on. To avoid supply shortages, manufacturers must secure a steady supply of raw materials and equipment, channel investments to the right areas, and execute large-scale industrialization efficiently. Moreover, rather than engaging in greenwashing, companies must commit to extensive decarbonization and true sustainability across the entire value chain.
Transitioning to a Sustainable, Circular, and Resilient Battery Value Chain
To become a sustainable, circular, and resilient industry, the battery sector must address a range of environmental, social, and governance (ESG) risks. These include issues such as CO2 emissions, water scarcity, biodiversity loss, human rights violations, and worker health and safety. Addressing these challenges will require a collaborative effort, the deployment of sufficient resources, and greater transparency and mitigation measures.
Many industry leaders recognize the urgency of this transformation. As Benedikt Sobotka, CEO of Eurasian Resources Group, states, “The lithium-ion battery value chain is set to grow by over 30% annually from 2022-2030, in line with the rapid uptake of electric vehicles and other clean energy technologies. The scaling of the value chain calls for a dramatic increase in the production, refining and recycling of key minerals, but more importantly, it must take place with ESG considerations at front and center.”
To achieve a sustainable, circular, and resilient battery value chain by 2030, the industry must focus on 10 transformational success factors:
-
Establishing Value Chain Circularity: Adopting circular business models, such as battery-as-a-service and second-life applications, can increase resilience and mitigate risks related to battery waste disposal.
-
Increasing Energy Efficiency and Electrification: Mastering energy efficiency in battery manufacturing, through measures like building insulation and heat recovery, is crucial.
-
Minimizing Environmental Impacts Beyond Climate: Going beyond just reducing carbon emissions, the industry must consider all planetary boundaries, including biodiversity protection.
-
Creating Positive, Just, and Inclusive Social Impact: Ensuring health, safety, fair-trade standards, and human rights, while fostering inclusive dialogues with local communities.
-
Sourcing 24/7 Low-Carbon Electricity and Heat: Procuring time-matched green energy solutions, enabled by long-duration storage technologies, to achieve deep decarbonization.
-
Establishing Full Supply Chain Transparency and Compliance: Leveraging harmonized, credible, and trusted data, such as the Global Battery Alliance’s Battery Passport.
-
Embracing Technology Innovation and Flexibility: Maintaining agility to adapt to rapidly changing market dynamics and adopt promising innovations.
-
Securing Raw Material and Machinery Supply: Exploring long-term agreements, co-funding, and other arrangements to ensure adequate supplies and avoid production delays.
-
Excelling in Cost and Regional Execution: Continuously improving battery costs, manufacturing efficiency, and capital expenditures to remain competitive.
-
Harmonizing International Standards and Regulations: Fostering dialogue and collaboration to align manufacturing standards and local regulations, reducing costs and barriers to scale-up.
By focusing on these transformational success factors, the battery industry can pave the way for a resilient, sustainable, and circular future, unlocking significant value and contributing to the global effort to mitigate climate change.
The Importance of Circularity and Battery Recycling
The current battery industry often operates as a linear value chain, with products disposed of after use. However, a shift towards circularity, which emphasizes reusing or recycling materials, can reduce greenhouse gas intensity while creating additional economic value.
Circularity can effectively couple the transport and power sectors, laying the foundation for transitioning to other energy sources, such as hydrogen and power-to-liquid, after 2025 to achieve the target of limiting the increase in emissions to 1.5°C above pre-industrial levels. Current regulations encourage circularity, and this model can bring numerous benefits, including fewer supply bottlenecks and reduced virgin raw material mining and refining.
Digital technology can play a crucial role in increasing circularity by providing the transparency and data management required to create an efficient ecosystem in which batteries and critical materials can be traced through end-of-life. As the recycling market matures, battery manufacturers may find new opportunities, potentially creating a closed-loop, domestic supply chain that involves the collection, recycling, reuse, or repair of used Li-ion batteries.
The recycling industry alone could create a $6 billion profit pool by 2040, with revenue exceeding $40 billion – more than a three-fold increase from 2030 values. However, current recycling business models are still costly and heavily dependent on various factors, including battery design, process quality, and shifts in market supply or raw-material demand. Regulatory incentives and corporate sustainability goals can provide strong reasons for companies to improve their recycling efforts by optimizing access to feedstock, technological processes, and strategic partnerships throughout the battery value chain.
Regional Trends and Localization Efforts
The value chain depth and concentration of the battery industry vary significantly by country. While China has many mature segments, cell suppliers are increasingly announcing capacity expansion in Europe, the United States, and other major markets, to be closer to car manufacturers. Partially due to recent regulatory changes, these new locations could provide almost 40% of global capacity in 2030.
Despite the rising local demand, China will likely continue to have significant overproduction capacity, while Europe and North America might not be able to meet their own local demand for cell production. Players in the battery value chain who want to localize the supply chain could mitigate these risks through vertical integration, localized upstream value chain, strategic partnerships, and stringent planning of manufacturing ramp-ups.
The battery value chain is facing both significant opportunities and challenges due to its unprecedented growth. It is one of the most ambitious scaling and ESG transformations that this highly complex and global product value chain has seen. Mastering this transformation, however, has the potential to create more than $400 billion in value-chain revenues by 2030, contribute to up to 18 million jobs along the entire value chain, and avoid around 70 GtCO2e in cumulative road transport emissions from 2021 to 2050.
Sustainable Battery Technologies and Decarbonization Strategies
Battery electric vehicles (BEVs) are widely recognized as the most effective decarbonization option for passenger cars. While BEVs have higher emissions during the manufacturing phase, they emit significantly lower emissions during the use phase compared to internal combustion engine (ICE) vehicles. In the worst-case scenario, with no low-carbon electricity, total life-cycle emissions for BEVs are about 50% lower in Europe and 72% lower in the United States compared to ICE vehicles. With low-carbon electricity during the use phase, BEVs achieve even better life-cycle carbon footprints, with about 77% lower emissions in Europe and 88% lower emissions in the United States.
To further decarbonize battery production, companies can leverage a variety of tactics, such as the use of circular materials and low-carbon electricity. In the best-case scenario, some of these tactics could result in cost savings, while others would entail large expenditures. Under the most beneficial circumstances, companies might potentially decarbonize up to 80% of emissions at a minimum additional cost.
Recent advancements in battery technologies, including increased cell energy density, new active material chemistries (such as solid-state batteries), and improved cell and packaging production technologies (like electrode dry coating and cell-to-pack design), present both opportunities and challenges for battery manufacturers. To manage uncertainty, battery cell manufacturers need to plan their target investments carefully, secure external funding, and optimize short- and long-term costs to ensure agility and adaptability of production lines.
