GE takes IISc's biomass tech to US

Business Standard:  September 09, 2015

Bengaluru: A home-grown technology to generate electricity using biomass designed by the Indian Institute of Science (IISc) is being taken to the US by General Electric.

GE, which had licensed the biomass gasifier technology that generates electricity from agro-waste and wood from IISc, will help Phoenix Energy set up power plants in California. GE demonstrated a model at its Tech event in Bengaluru over the weekend. “Technology transfers typically happen from the North to the South. In gasifier technology, it flows from the South to the North,” said S Dasappa, professor, Centre for Sustainable Technologies, IISc.

“GE officials had scouted across the globe and found this platform – power generation from biomass at IISc. The technology available with us is the best in the world.” While the indigenous gasifier technology gets a US presence, and has installations in countries such as Zambia, the uptake in India is still very slow.

Bioresidue Energy Technology, a Bengaluru-based licencee, has seen one of its projects in Mangaluru shut and another 1.2 mega watt (Mw) power plant generating below capacity in Gadag with revenue from electricity distribution companies not matching up with the cost.

In Karnataka, it costs Rs 6 to generate one unit of electricity, while the power generator is compensated with Rs 6.40 per unit.

“It is uneconomical to run these plants at this cost,” said Amar Kumar, founder of BETP.

India has a vast amount of biomass waste – wood chips from trees such as eucalyptus, coconut shell, sawdust, sugar cane trash and coffee husk - that can be converted into energy. The scientists at IISc estimate India can generate 15,000 Mw of electricity using agro and crop waste of 120-140 million tonnes using a distributed model of having 1-6 Mw power plants across the country.

“There is little parity with biomass and solar and other renewable energies. If it happens – this can provide grid quality 24/7 power giving direct and indirect employment,” said Dasappa. “We are looking at a level-playing field.”

Karnataka offers as much as Rs 12 a unit of power generated by solar, but pays less to biomass-based gasifier projects.
