Investment Economics

Market Awareness BarrierThe industry is at its infancyAmongst top management of industryAmongst technical consultants to the industry

Technology BarrierLack of standardization of application covering CST technology, process integration & heat storage

Financing BarrierTechnology risk perceived by lendersNo testing facility No publicly available performance data

Why don’t we see widespread use?

Policy related BarriersLack of financial incentives based on performance – favoring low-efficiency technologiesREC mechanism does not include steam generationHigher subsidy for organizations that cannot avail accelerated depreciationHigher subsidy for economically unviable but promising applications like solar cooling, desalination, etc

Why don’t we see widespread use?
