Mobile thermal energy storage based on recycled ceramics


Today heavy industries lose 20-40% of the energy they consume through waste heat. Above 200°C, these losses represent each year more than 4,000 TWhth, €200bn, 2,500 Mt CO2.
Waste heat recovery solutions have emerged: they offer massive potential in costs/energy savings as well as reduction of environmental impact. However, due to financial viability, existing solutions are mainly implemented for large industries & not compatible with all types of processes. Main challenge is to offer reliable, efficient & affordable heat recovery solution with reduced CAPEX & OPEX.
Our solution is based on 3 innovative concepts:
- The elaboration of ceramics from industrial wastes, such as refractory ceramics for thermal storage;
- The implementation of those ceramics in a thermal energy storage unit EcoStock. EcoStock is an efficient, affordable & low risk technology;
- The financial scheme design facilitating & de-risking the customer purchase, based on ESCO investment.
This solution solves one of the main challenges of the industry—increasing energy efficiency while reducing CO2 emissions & saving money.
Waste heat recovery is a global multisector market: 50,000+ industrial sites in various sectors are concerned & thousands of EcoStock units could be sold. The market size of waste heat recovery systems was €39.3bn in 2015, projected to reach €58.8bn by 2021. It is a high-volume market. underexploited because of high CAPEX & low flexibility of existing solutions.
To reach the commercialisation objective, the Phase 2 project budget is €1.9m for 24 months.
