Supply chain dynamics in the battery energy storage industry globally are influenced by several factors that span from raw material extraction to end-product delivery. All are interdependent on another to ensure an efficient supply chain to cope with the speed of innovation, market demand and socio-ethical practices too.

Navigating the energy storage supply chain is a key challenge for those investing in utility-scale BESS, so in this Insights article, we’re going to outline the 2024 outlook and shed some light on the current situation as we see it playing out.

Key aspects of the energy storage supply chain

Raw material sourcing

The battery energy storage industry heavily relies on raw materials such as lithium, cobalt, nickel, manganese and graphite. The supply of these materials is geographically concentrated with only a few key players globally contributing to a significant portion of the supply. Political instability, environmental concerns and trade policies in these regions can significantly impact raw material availability, leading to price volatility and supply disruptions.

Manufacturing and processing

Battery manufacturing involves complex processes including the production of cathodes, anodes, electrolytes, and separator materials, followed by cell assembly and packaging. The industry is witnessing rapid technological advancements, with continuous improvements in battery chemistry, energy density and longevity. This requires manufacturers to constantly adapt and upgrade their production capabilities, which can strain the supply chain.

Most mass-manufacturing and processing occurs in East Asia with countries like China dominating this part of the supply chain so it’s critical, especially for Western countries, to have strong partnerships in the regions for maximising efficiency.

Supply chain logistics

Following on from processing, it’s then the transportation of raw materials, intermediate products and finished batteries that involves logistical challenges, given the hazardous nature of some battery components. Regulations governing the transport of batteries, especially by air, can affect supply chain efficiency and costs.

The industry, as has been reported in recent years, is also impacted by global shipping trends, port capacities and trade routes, with disruptions such as port congestion or shipping delays having a cascading effect on the supply chain.

Regulation and sustainability

Increasing scrutiny on the environmental and social impacts of battery production, especially concerning cobalt and lithium mining, is leading to more stringent regulations and a push towards more sustainable practices.

With growing manufacturing prominence comes the necessity for traceability and environmental compliance across the board. This involved ensuring that components, especially those sourced from diverse global locations, meet stringent environmental and quality standards.

Recycling and ‘second life’ applications for batteries are becoming an integral part of the supply chain, offering potential relief to raw material scarcity but also adding complexity in terms of collection, processing and reintroduction into the manufacturing cycle.

Market demand and innovation

The demand for battery energy storage is growing rapidly, driven by the expansion of renewable energy integration and improving grid network stability. This puts pressure on the supply chain to scale up production without compromising quality and cost.

While batteries are generally readily available, other components like AC solutions, transformers and switchgear often have longer lead times, which can bottleneck project deployments. Reliable supply chains are thus essential.

Innovation in battery technologies, such as solid-state batteries, silicon anodes and alternative chemistries, could disrupt existing supply chains by changing raw material needs or manufacturing processes.

Geopolitical and economic factors

Trade policies, tariffs and geopolitical tensions can significantly affect the supply chain. For example, tariffs on imported materials can increase costs, while geopolitical tensions can lead to restrictions on raw material exports.

Economic conditions, including inflation, exchange rates and economic growth rates, can also impact investment in mining, manufacturing capacity – and ultimately – the price and availability of battery storage solutions.
