Expected ROI of sodium ion battery storage project in Ireland 2025

Are sodium-ion batteries the future of energy storage?

Sodium-ion batteries are being leveraged across multiple industries. Utility companies are at the forefront of their deployment, as demonstrated by HiNa Battery’s 100MWh energy storage project. These batteries provide an affordable alternative for renewable energy grid storage, helping stabilize energy supply.

Will lithium-ion batteries meet Ireland's energy storage needs in 2035?

Lithium-ion batteries were assumed to be a key technology option for meeting Ireland’s energy storage needs towards 2035, with a wider mix of technologies being deployed to achieve 2050’s net zero targets.

Will 2025 be a pivotal year for sodium-ion batteries?

With ongoing innovations and substantial investments, their adoption in energy storage systems, renewable grids, and budget EVs is expected to soar in the coming years. In conclusion, 2025 marks a pivotal year for sodium-ion batteries.

Will sodium ion batteries increase energy density?

This company continues to progress in the development of sodium-ion batteries with the intent to increase energy density and market their solutions as substitutes for lithium-ion batteries. In December 2022, Svolt Energy unveiled its inaugural sodium-ion battery prototype, boasting an energy density of 100 Wh/kg.

Are sodium-ion batteries competitive?

As of 2025, sodium-ion batteries are well-positioned to achieve cost parity with lithium-iron-phosphate (LFP) batteries, a key milestone for market competitiveness. With ongoing innovations and substantial investments, their adoption in energy storage systems, renewable grids, and budget EVs is expected to soar in the coming years.

What types of batteries can be stored in Ireland?

These include lithium-ion batteries, hydrogen storage, thermal storage, flow batteries and pumped hydro storage. However, thermal storage fell outside of the focus on electricity storage and the potential for additional pumped hydro storage in Ireland is considered to be fairly limited and so neither were modelled in detail.
