HEION & HEIONTEC
HEIONIT GmbH is a spin-off of HEION GmbH, which has developed a modified fuel and successfully launched it on the market as HEION CLEAN DIESEL (EN 590). During the production of HEION CLEAN DIESEL, a process water is produced as a residual substance in a patented process.
This process water is the main component of HEIONTEC TEC-G cells and enables resource-saving, sustainable and cost-effective cell production through this upcycling process. By dispensing with expensive, imported materials used in conventional battery construction (e.g. lithium), HEIONTEC production is independent of geopolitical tensions and imports and has a better carbon footprint.
