RESUMO: Excluídos os usos não energéticos de fontes de energia primária, os consumos de energia final (FEC) associados à produção de calor de processo no sector Industrial correspondem, à escala global, a 23% do FEC total entre todos os sectores. Apresentando o potencial de suprir as necessidades de calor de processo a baixa e média temperatura – 52% das necessidades – a sua penetração actual no mercado corresponde, à escala global, a cerca de 0,1% da capacidade total instalada em energia solar térmica. Resolvidas que estão muitas das questões técnicas e tecnológicas que poderiam apresentar-se como limitações à adopção destas tecnologias pela indústria, esta fraca penetração deve-se, sobretudo, a questões de competitividade económica. O presente artigo analisa as condições de fronteira críticas para a competitividade do calor de processo solar, tendo por base cenários de evolução de custos da tecnologia, fontes de energia primária e valorização de emissões evitadas. Nesta análise é avaliado o impacto de diferentes modelos de negócio na competitividade desta solução.
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.
