Workshop on “Energy Efficient Japanese Technologies and Best Practices in Compressed Air System” held at Pune on 11th October, 2014

An awareness workshop on ‘Energy Efficient Japanese Technologies and Best Practices in Compressed Air System’ was organised on 11th October 2014, at Courtyard Marriott, Pune by TERI and Institute for Global Environmental Strategies (IGES), Japan in collaboration with Maharashtra Energy Development Agency (MEDA). About 45 participants from government, industry, consultancy agencies and donor organisations attended the event. A summary of the deliberations at the workshop is presented below.

Mr Chetankumar Sangole, TERI welcomed the Japanese compressed air experts and other delegates to the event. He also gave an overview of the activities being undertaken by TERI and IGES to disseminate Japanese energy efficient technologies among industry in India.

Mr Hemant Patil, MEDA gave the inaugural address. He mentioned that Japan is well known for energy efficient technologies and hence such bilateral cooperation will be of great mutual benefit. MEDA provides support for energy audit studies and also gives financial assistance for implementation of energy efficiency projects. He urged the units to conduct energy audits and take the help of organisations like TERI for energy efficiency improvements.

Mr Prosanto Pal, TERI gave an overview of the proposed bilateral ‘Joint Crediting Mechanism (JCM)’, between India and Japan and mentioned that the mechanism would provide a good opportunity for financing of new energy efficient Japanese technologies for adoption in India. He also mentioned about TERI’s activities among forging units in Pune cluster under the World Bank-GEF program.

Dr Rabhi Abdessalem, IGES made a presentation on the ALCT project, undertaken by IGES and TERI with support from JICA/JST. Under the project, hard technologies like Gas Heat Pump (GHP) and Electric Heat Pump (EHP) and soft technologies in compressed air and induction furnaces were demonstrated among SMEs in India. In future, the JCM scheme can be used to implement low carbon Japanese technologies in India and support under Climate Technology Centre and Network (CTCN) of UNFCCC can also be explored.

Mr Tsukasa Saito, Hitachi Industrial Equipment System, Japan made a presentation on ‘Best Practices in Compressed Air Systems’. He mentioned that the air compressor consumes between 20-40% of the total energy in many industries. Typically, in an air compressor’s life cycle, cost of operation (energy) is 84%, capital cost is 7% and maintenance cost is 9%. He highlighted the need to reduce the consumption of compressed air and reduce the compressed air generation pressure wherever possible before optimizing the air compressor itself. He emphasised various areas which are important for efficient operation of air compressors such as pipe sizing, reducing unloading time, reducing the use of valves, epoxy coating of air receiver, providing drain valves, proper sizing of filter and air dryer, closed loop system, use of two stage compressor, use of invertor compressor, proper sizing of air receiver, use of exhaust ventilation ducts, use of nozzles and many such measures.

The workshop ended with a vote of thanks by Mr Kailash Tarde, TERI.
