Will water-based batteries be the future of sustainable energy storage?

February 27, 2024


In the ever-evolving landscape of sustainable energy storage, a new promising solution has emerged on the horizon: water-based batteries. As the world grapples with the urgent need to transition away from fossil fuels, researchers are tirelessly seeking efficient and eco-friendly solutions. Could water-based batteries hold the key to unlocking a future where renewable energy is harnessed, stored, and distributed in unprecedented ways? This blog delves into the promising realm of water-based batteries, exploring their potential, future outlook, and usage to decipher whether they truly embody the future of sustainable energy storage.

The Need for Sustainable Energy Storage

As renewable energy sources like solar and wind power become increasingly prevalent, the intermittent nature of these sources poses a challenge. Energy generation might not align with energy consumption, leading to a shortage of power during peak demand. Efficient energy storage is crucial to address this problem, enabling a consistent supply of electricity and reducing reliance on fossil fuels.  So, as a result of this problem, an emerging solution of water-based batteries arises which can hopefully solve the need for sustainable energy storage.

Rise in Renewable Energy Capacity

By 2023, the global renewable energy capacity will reach over 2,600 gigawatts (GW), which is nearly 30% of the world's total electricity generation capacity. Battery storage systems, such as lithium-ion batteries, are instrumental in smoothing out the intermittency of renewable energy sources like solar and wind. They store excess energy when generation is high and release it when demand is high or generation is low. This ensures a stable and reliable electricity supply.

Water-Based Batteries: A Promising Solution

Water-based batteries, also known as aqueous batteries, have the potential to solve the energy storage issue. They are sustainable, safe, and scalable. These batteries employ water as the primary component in their electrolytes, replacing hazardous and expensive materials found in traditional lithium-ion batteries. This not only enhances safety but also reduces the environmental impact of battery production, use, and disposal.

Basics of Water-Based Batteries

Water-based batteries employ water as one of their primary components. Unlike traditional lithium-ion batteries, which rely on lithium-ion movement through an electrolyte, these batteries utilize the movement of ions in and out of water-based solutions. Two primary types of water-based batteries have gained attention: the aqueous hybrid ion (AHI) battery and the aqueous lithium-ion battery.

How Water-Based Batteries can be used?

Water-based batteries are well-suited for various applications:

  • Grid-Level Energy Storage

Aqueous batteries can store excess renewable energy generated during periods of high production (e.g., sunny or windy days) and release it during times of high demand or low renewable energy availability.

  • Electric Vehicles

Aqueous lithium-ion batteries could enhance the safety of electric vehicles while providing sufficient energy density for extended driving ranges.

  • Consumer Electronics

Smaller-scale water-based batteries can power laptops, smartphones, and other portable devices, reducing the risk of thermal incidents in everyday gadgets.

  • Industrial Use

In industries such as renewable energy storage, grid stabilization, and backup power systems, water-based batteries provide a reliable means of storing and releasing energy.

Future Outlook

The future outlook for water-based batteries appears promising, given their potential to address critical energy storage challenges. These batteries utilize water as an essential component in their electrolyte system, enhancing safety, affordability, and environmental sustainability. Research and development efforts are focusing on improving the efficiency, energy density, and cycle life of these batteries to make them competitive with existing energy storage technologies.
