Batteries play a crucial role across various industries, significantly impacting electric vehicles (EVs), renewable energy integration, and consumer electronics.

  • Electric Vehicles (EVs) - Batteries are at the core of the electric vehicle movement. As we move away from fossil fuels, the need for batteries that are efficient, long-lasting, and quick to recharge has grown significantly.

  • Renewable Energy Integration - Batteries play a key role in balancing the power grid by storing extra energy from renewable sources like solar and wind, then releasing it when demand is high. Large-scale battery storage systems are becoming more important to ensure a steady and reliable energy supply.

  • Consumer Electronics - Batteries have transformed consumer electronics, powering everything from smartphones and laptops to wearable devices and portable gadgets. The push for longer battery life, faster charging, and smaller power sources has led to major innovations in this area.

There are many factors driving global demand for energy storage and battery technology, placing them at the heart of the future of energy and transport, namely:

  • Push for decarbonization - Many countries and companies setting targets to become carbon neutral by 2050. Batteries are crucial in this transition, enabling the shift from fossil fuels to cleaner energy sources by storing renewable energy and powering electric vehicles, thereby reducing greenhouse gas emissions.

  • Electric vehicle growth - The rapid expansion of the electric vehicle market is one of the main drivers of demand for batteries. This is not only shaping the automotive industry, but also driving innovation in battery technology, as companies strive to improve energy density, reduce charging times and cut costs.
  • Advances in renewable energy technology - The cost of renewable energy technologies, particularly solar and wind power, has fallen considerably, making them more competitive with fossil fuels.

Investment Opportunities in Energy Storage and Battery Innovation 

  • Lithium-ion Batteries - Lithium-ion (Li-ion) batteries dominate the energy storage market, making up over 90% of global battery production. Known for their high energy capacity (typically around 150-250 watt-hours per kilogram), efficiency, and long lifespan (often over 1,000 charge cycles), these batteries are crucial for powering electric vehicles and renewable energy storage systems. As demand for EVs continues to grow, with global EV sales projected to reach over 40 million units annually by 2030, the Li-ion battery market is expected to expand significantly.

  • Solid-State Batteries - Solid-state batteries, an emerging technology, aim to replace the liquid or gel electrolytes in traditional Li-ion batteries with a solid electrolyte. This could increase energy density by up to 50%, improve safety by reducing the risk of fires, and extend battery life to over 2,000 charge cycles. While still in the development stage, the global market for solid-state batteries is expected to reach $6 billion by 2030, driven by demand for safer, more efficient batteries in EVs and other applications.

  • Flow Batteries - Flow batteries, which store energy in liquid electrolytes held in external tanks, offer a unique advantage with their ability to scale easily and provide long-duration energy storage, often exceeding 10 hours. This makes them ideal for large-scale applications like grid storage. The global flow battery market is set to grow to over $1.3 billion by 2030.

  • Alternative Storage Technologies - Pumped Hydro Storage is the most established large-scale energy storage technology, accounting for over 90% of the world’s energy storage capacity, with an estimated global installed capacity of 160 gigawatts. It provides long-duration storage and grid stability, making it a reliable and cost-effective solution for utility-scale energy storage. Despite the rise of newer technologies, pumped hydro remains a dominant player, especially in regions with suitable geography.

Emerging Trends & Growth Areas 

We are noticing some key trends within the industry. For example, research into new battery materials, such as silicon anodes, lithium-sulfur, and lithium-air, is pushing battery performance and capacity forward. These developments aim to increase how much energy batteries can hold, lower costs, and extend their lifespan, making them more practical for a wider range of uses.

As electric vehicles become more common, there's growing interest in repurposing their batteries once they're no longer suitable for driving. These used batteries can find a second life in less demanding applications, like stationary energy storage, which extends their usefulness and contributes to sustainability by reducing waste.

Or in grid-scale energy storage, recent advancements have focused on boosting energy capacity, making it easier to store renewable energy and support the integration of variable sources like solar and wind into the power grid.
