Abstract
The condensation of silica to form hard scale is a major issue in the generation of energy from geothermal resources. Presented here is nano-structured calcium silicate (NCaSil) as a solution to this issue. NCaSil prevents the unwanted silica deposition by formation of a competing product, which is highly porous and interesting for various applications in materials science. The progression and development of NCaSil technology from laboratory experiments to batch field trials and pilot scale experiments will be shown, and the potential for its implementation on industrial scale outlined.
