Analysis of the entire life cycle

The analysis by the specialists from Freiburg contains the entire life cycle of the battery. The check started with the production of the battery cell made in Austria, through use by the end customer, to recycling at the end of the life cycle. Further, extreme scenarios such as external fire were taken into account in the analysis.

Objective analysis is important to BlueSky Energy

It was important to the team of BlueSky Energy that an independent, external institute conduct a rigorous, objective analysis of the technology. The environmental friendliness, safety and sustainability of the technology is at the core of BlueSky Energy’s corporate philosophy of storing “green energy” in a “green battery”.

Further development of battery technology

The saltwater battery technology developed in Austria is a further development of the “Aqueous Hybrid Ion – AHI” technology, which successfully underwent cradle-to-cradle certification for the Aquion company several years ago.
