Calor de processo solar: competitividade e necessidade de modelos de financiamento

Abstract

Excluding the non-energetic uses of primary energy sources, process heat related Final Energy Consumption (FEC) stands, worldwide, to 23% of the total FEC (among all sectors). Presenting the potential to supply industry with low and medium temperature heat demands – 52% of the overall heat demand in industry – solar process heat market penetration is marginal, standing for about 0,1% of the total installed capacity of solar thermal energy. With many of the technical and technological questions which could impair he adoption of solar thermal technologies in industrial applications, this weak market penetration is mostly due to economic competitiveness reasons. The present article assesses the critical boundary conditions for the competitiveness of solar process heat. Based in different technology, conventional energy sources and emission cost scenarios, this assessment presents the impact of different business models in the competitiveness of this technological option.
