Nanouptake – Overcoming Barriers to Nanofluids Market Uptake (COST Action CA15119) aims to create a Europe-wide network of leading R+D+i institutions, and of key industries, to develop and foster the use of nanofluids as advanced heat transfer/thermal storage materials to increase the efficiency of heat exchange and storage systems. By developing of nanofluids up to higher Technological Readiness Levels (TRL) and overcoming commercial application barriers, Nanouptake will contribute to achieve the European Horizon 2020 Energy and Climate objectives (Societal Challenges 3: Secure, efficient and clean energy; and 6: Climate action, environment, resource efficiency and raw materials).
