India: UNDP-GEF Project Paves Way for Commercialising Industrial Process Heat

Dr GoswamiThe five-year UNDP-GEF project Market Development of Concentrating Solar Thermal Heating (CSH) Technologies for Process Heat Applications has paved the way towards commercialisation. The objective was to accelerate demand for CSH systems in industrial, commercial and public facilities by organising stakeholder workshops, strengthening the industrial supply chain and implementing quality assurance measures. Solarthermalworld.org spoke with Dr R P Goswami, National Project Coordinator and Director at the Ministry of New & Renewable Energy, about CSH market development in India.

Solarthermalworld: How would you sum up the results of the GEF-UNDP CSH programme? 
Goswami: MNRE’s efforts during the UNDP-GEF CSH project have led to significant growth in the concentrated solar thermal sector, with installations across industrial and commercial sectors driving down costs of procurement and installation. We have supported 45,500 m² of CSTs for cooking, process heating and cooling applications between 100 and 300 °C and expect 35,000 m² to be commissioned by 30 September 2017, at the end of the project (see table about the support scheme below). We have also established the first facilities for testing system performance in the country.
 
The project has additionally led to the creation of many knowledge base documents, among them training manuals in Hindi and English on O&M, plus troubleshooting, for various CSTs, performance standards in terms of anticipated heat delivery in different regions and manuals for a bank’s loan appraisal of CST proposals, etc. This programme will have long-term gains and has paved the way for commercialisation.
 
Solarthermalworld: How did you spread awareness during your GEF-UNDP CSH programme? 
Goswami: Over 70 workshops and business meetings have been organised all over the country during the programme duration. They targeted industrial and institutional stakeholders and had around 3,000 participants. As one of the supporting partners, the World Renewal Spiritual Trust, created a training and awareness centre, conducting nine seminars for potential beneficiaries and six training sessions for technicians. There is also a new website – cshindia.in – for providing comprehensive information about CSH activities, case studies, policy announcements and video films on successful projects. The programme has likewise resulted in the publication of a monthly newsletter www.insolthermtimes.in, a quarterly magazine called SUNFOCUS and a national toll-free helpline. 
 
Solarthermalworld: Industrial process heat is still a niche segment in India. What are your thoughts on its long-term potential? 
Goswami: There is great potential. Huge amounts of subsidised electricity and fuel oil or LPG are being used for heating, cooling, process and drying applications in the country. Estimates speak of more than 15 million tons of fuel oil for industrial heat at up to 250 °C and of about 500 trillion kWh of electricity being consumed annually in several sectors to heat water and air. Even if only 1 % of this fuel could be saved thanks to CSH systems – keeping in mind space and DNI availability at factory sites – a mirror area of about 2 million m² would seem to be a realistic countrywide target.
 
Solarthermalworld: How has your programme addressed financing issues?
Goswami: Seminars for senior representatives from banks and financial institutions were conducted to inform them about the options for providing loans to manufacturers and industrial end users. As a result, Syndicate Bank, United Bank of India, State Bank of Bikaner & Jaipur and State Bank of Patiala have issued circulars on providing loans at prime interest rates. This provided manufacturers and technology suppliers with the motivation to initiate ESCO projects, where they put up plants themselves and sign long-term heat supply contracts with clients. Four such projects are being implemented right now – one for process heat at Hatsun Agro’s dairy factory in the city of Chennai (Madras) and three for community cooking in institutions. This model is expected to improve the confidence of beneficiaries and ESCOs, leading to a win-win situation for both.
 
Solarthermalworld: Could you say something about the quality and standards from your programme?
Goswami: To address the issue of system quality, there have – for the first time in the country – national and regional test centres (mobile and stationary) been established at the National Institute of Solar Energy in Gurugram and the Savitribai Phule University of Pune. The previous lack of facilities meant that the performance of installed systems was not gauged. In addition, there are handbooks on component & material specifications for six CSH technologies available to provide guidance for suppliers and beneficiaries, resulting in the Bureau of Indian Standards issuing specifications for various CSH technologies and test methods (see end of interview).
 
“More start-ups need to offer monitoring solutions”
 
Solarthermalworld: What have been the takeaways from a first assignment of online monitoring systems to 15 locations?
Goswami: Unfortunately, we were faced with unforeseen difficulties when monitoring existing solar process heat plants. The online performance monitoring instruments primarily measured weather parameters, thermal output and data acquisition and management. A lack of standardised online monitoring systems resulted in non-uniform approaches towards data acquisition, transmission and analysis. We did not publish a comparison of results from these 15 locations, but the monitoring benefited individual CSH users by providing essential information on how to optimise their system.
 
Solarthermalworld: What are your recommendations for improving the transparency of performance information?
Goswami: Based on our experience with this first monitoring assignment, on-site monitoring has been made compulsory for all installations supported under the UNDP-GEF programme in India. Progress, however, has not been satisfactory due to solar thermal manufacturers’ and system suppliers’ lack of knowledge and experience.
 
We recommend that system suppliers provide a complete monitoring unit, whereas the MNRE may think of integrating online monitoring into the CSH subsidy scheme. There should be compulsory after-sales services, including monitoring, and more start-up companies need to offer monitoring solutions, as this involves major IT and communication technology components. Sites in remote areas may receive additional support for implementing online monitoring.
 
“Solar heat sector has not been attracting as much attention as solar electricity”
 
Solarthermalworld: PV has already reached a high level of commercialisation in India. Do you think that this will also possible for CSH?
Goswami: Yes, but not only for CSH systems. Other solar thermal technologies also have potential to achieve commercialisation. Whereas solar water heaters are useful for low-temperature applications, CSH systems provide vast opportunities at medium and high temperatures. Demand for thermal and electricity generation is almost equal in industry, but the solar heat sector has not been attracting as much attention as solar electricity at national level. The focus needs to be put on solar thermal technologies by introducing PV-like policies. Volumes and policy initiatives, both in terms of fiscal and financial incentives and technology improvements, could help CSH systems become viable.
