Heiwit has reached a major strategic milestone in the development of sodium-ion batteries, an innovative technology that is set to revolutionise the energy storage market. Heiwit is preparing its own factory in Italy: the first phase, with construction planned from 2027, is sized for about 12,000 battery packs a year (about 100 MWh), with the goal of reaching 3 GWh a year within three years of start-up. These are project targets, not capacity already available.
This production project aims to position Heiwit significantly in the fast-growing European energy storage landscape, which is increasingly oriented towards sustainable and safe solutions. The sodium ion batteries offered by Heiwit represent a viable alternative to traditional lithium technologies.
Heiwit is already marketing the 10 kWh home version and is also developing a version for three-phase high-voltage systems: availability and specifications will be announced at launch.
Sodium-ion batteries also work without lithium: sodium is a far more abundant and widespread element.
Moreover, the sodium batteries proposed by Heiwit are characterised by a lower operational risk, operating stably at moderate temperatures (around 30°C), and a more sustainable and less complex supply chain.
Heiwit, therefore, presents itself as an emerging strategic player in the European energy storage scene, with significant growth prospects thanks to the sodium-ion technology of its batteries.
Behind the announcement on production capacity lies a range already in the catalogue: find out how Heiwit sodium-ion batteries are made and the 10 kWh domestic version already on the market.
