The general goal of COCO is to avoid or mitigate high temperature corrosion of candidate low cost material systems for new generation Brayton cycle CSPs.
The general goal of COCO is to avoid or mitigate high temperature corrosion of candidate low cost material systems for new generation Brayton cycle CSPs.
COCO’s hypotheses are based on developing stable, lower cost and less corrosive molten salt mixtures and using coatings on mechanically stable stainless steels to replace Ni base materials.
Technical Advantages
Economically viable technology to win advantage over other renewable energies and fossil fuel.
Cost savings
Materials more efficient that allow and resist the new operating conditions, but, without increasing costs.
Energy efficiency
Increase the operating temperature of the plants to reach higher efficiencies. Brayton power cycle using supercritical CO2
The COCO project focuses on the development of new materials and structural coatings advanced long-term performance for two key components.
Molten Salt Fluids
new molten salt mixtures with a higher thermal stability point are required (up to 700ºC) to increase plant efficiency.
CO2 Energy Cycle
s-CO2 is considered as a working fluid in the new Brayton power cycles due to its very low economic value.
