Solutia's heat transfer fluid was chosen for use in two solar power plants in Spain.

A Therminol heat transfer fluid from St. Louis-based Solutia Inc., has been chosen for use in two solar power plants in Spain. Synthetic fluid Therminol VP-1 will be used in the projects, which are each 50 MW solar power plants with thermal storage.

Heat transfer fluid is used in the trough-shaped mirror assemblies to absorb concentrated sunlight, heating up to about 752°F (400°C). The stored heat can be used to produce energy during periods of little to no sunlight, including evening hours. The heated Therminol is used to generate steam, which drives the power-generating turbines.
