There is currently no question of bankruptcy, Sanders emphasizes. "But we are indeed winding down," she says. "We see no opportunities to commercialize our product." At the end of February, the shareholders will decide on the future of Cellcius. In addition to TU/e and TNO, Vereniging Eigen Huis and several private ‘angel investors’ are co-owners of the company.

Cellcius worked on a salt battery to store heat. In the energy transition, the storage of sustainable energy is one of the major challenges, because solar panels and wind turbines only supply energy when the sun shines and the wind blows. The promise of a salt-based heat battery attracted investors. In June 2022, Cellcius received a capital injection of 1.2 million euros

The Cellcius website states that after previous successful test setups in Eindhoven and France, "the first home batteries will be installed at a number of 'launching customers' in 2026". The company was also working on a 'broader market introduction'. At this stage, CEO Sanders does not want to provide further explanation about the events that led to the decision to wind down the company.

It is still unclear what the future holds for Cellcius. The company could simply close down, but a takeover by another company may also be a possibility.
