Solar Thermal market demands improved molten salts for heat storage and heat transfer
Yara has the Nitrates expertise
Yara produces several CN grades and formats
Existing literature regarding Calcium Nitrate use in solar thermal power
Yara researched and tested to identify a nitrate grade with the optimal thermal performance:

Next Generation eutectic molten salt solution from the worldwide leader in nitrates

Synthetic
Chloride-free
Very pure
Competitively priced


Eutectic Molten Salt with CN-K melting process
Improvements over binary salts:
Lower melting point
Broader ΔTª
Reduced risk of molten salt solidification
Corrosion tests show eutectic CN-K Molten Salt to be significantly less corrosive than binary salts
Euctectic CN-K Molten Salt:Performance Benefits & Cost savings in Solar Thermal Electricity Plant Construction & Operation
Lower CAPEX: Yara CN-K scale advantage translates into lower-cost molten salt mix, pushing down solar energy cost

Lower melting point: 131 ºC
Wider delta Tª opens new operational possibilities and means you need less of the molten salt blend to generate power
Reduced risk of molten salt solidification: a technical challenge causing plant damage, stoppage and maintenance costs for current molten salt technologies

Lower start-up energy costs: Less energy needed to melt the ternary mixture including CN-K

Lower life-cycle cost: less corrosive eutectic CN-K molten salt mix reduces maintenance costs
