The saltwater batteries market size has grown rapidly in recent years. It will grow from $16.68 billion in 2025 to $19.98 billion in 2026 at a compound annual growth rate (CAGR) of 19.8%. The growth in the historic period can be attributed to concerns over lithium ion battery safety, increasing demand for renewable energy storage, early adoption of alternative battery chemistries, environmental regulations promoting non toxic materials, growth of off grid power systems.
The saltwater batteries market size is expected to see rapid growth in the next few years. It will grow to $38.43 billion in 2030 at a compound annual growth rate (CAGR) of 17.8%. The growth in the forecast period can be attributed to rising deployment of residential energy storage systems, expansion of renewable energy installations, demand for sustainable battery recycling solutions, increasing government investments in green energy storage, growing need for long cycle life stationary batteries. Major trends in the forecast period include rising adoption of environment friendly and non toxic battery technologies, increasing use of saltwater batteries for stationary energy storage, growing preference for fire safe and non flammable energy storage systems, expansion of low cost battery solutions for off grid applications, advancements in sodium ion and magnesium ion based saltwater batteries.
The increasing demand for energy storage is expected to drive growth in the saltwater batteries market in the coming years. Energy storage involves capturing energy produced at one time for later use, helping to balance energy demand and production. This demand is rising due to decreasing costs, the widespread adoption of renewable energy sources, the necessity for reliable and resilient grids, and supportive policies such as tax incentives. Saltwater batteries offer a safe and environmentally friendly solution for energy storage, utilizing abundant materials and posing minimal environmental risk. For example, in April 2024, the International Energy Agency, a France-based autonomous intergovernmental organization, reported that battery storage had become the fastest-growing commercially available energy technology in the power sector. Global deployment more than doubled year-on-year, with 42 GW of new battery storage capacity added across utility-scale installations, behind-the-meter systems, mini-grids, and solar home systems for electricity access. Thus, the growing demand for energy storage is a significant driver of the saltwater batteries market.
Key players in the saltwater batteries market are concentrating on developing advanced products, such as eco-friendly saltwater batteries, to enhance their competitive position. Eco-friendly saltwater batteries use a saline solution as an electrolyte instead of toxic chemicals, ensuring environmental safety. For instance, in January 2024, Salgenx, a US-based provider of energy storage solutions, introduced an innovative saltwater battery designed for residential energy storage. This battery employs sodium chloride (NaCl) for charging and recombination, offering a safe and environmentally friendly alternative to traditional batteries. Unlike conventional models, this redox flow energy storage system operates without a membrane and uses non-flammable saltwater, ensuring exceptional safety. Its modular design allows for flexible installation in various settings, such as garages, underground facilities, or integrated into building structures. With a storage capacity of 126 kWh, the Salgenx battery can be expanded with additional electrolyte liquid and cathode materials, achieving impressive efficiency of 91% and a power output of 20 kW.
In December 2023, Statkraft AS, a Norway-based renewable energy company, partnered with Aquabattery to develop and commercialize an innovative saltwater flow battery technology known as LDES. This technology aims to enhance long-term electricity storage capabilities using saltwater, testing scalability and commercial viability in Delft, the Netherlands. AquaBattery B.V., based in the Netherlands, specializes in sustainable and safe long-term energy storage solutions.
