EngEChrom project addresses the main objective of ENERGY Theme of HORIZON 2020, focused on the “Secure, Clean and Efficient Energy“. Energy saving is the most debated topic of the 21st century. Improvements in energy saving are achieved by adopting efficient technology or by applying methods to reduce energy losses. One real alternative is the development of glazing application which allows tunable transmittance of solar energy and visible light. This type of glazing is often called “smart” and is based on chromic materials, with electrochromic (EC) materials being currently the most widely studied. The main objective of EngEChrom is to develop novel polymeric materials with a double electron donor topology to be employed as active layers in prototype EC devices with low operating voltages for energy saving. Our previous results and technical skills placed us at TRL2 and allowed us to engineer suitable electrochromic materials still insufficiently explored. The conditions for TRL3 will be fulfilled by the investigation methods and tools, which will predict the electrochromic behaviour. The TRL4 proof of concept will be validated by engineering and optimization of prototype EC devices at lab scale as to achieve long-term stability, rapid switching, high coloration efficiency and low voltage operation. The fabrication and characterization of the prototype EC devices will fit the standards required by this research topic. To ensure the best practice, the work plan was divided into 3 work packages with specific objectives, ranging from material feasibility to assessment of the prototype EC devices performances. The potential risks, approaches for mitigation these risks, deliverables and milestones associated with each work packages are also described.
