"ile solar PV based captive power generation is in its infancy, there are specific market segments which have clean pain points that could be addressed well by solar PV. As a result, these segments are likely to have a much higher adoption of solar PV for captive power generation Solar PV is most cost competitive as a replacement for diesel-based power production. India has about 7,000 MW of diesel based power production in MW scales alone, with hundreds of thousands of diesel gensets used in diverse commercial locations from over 2,50,000 mobile telecom towers to over 5 million diesel based agricultural pump sets, and with tens of thousands of companies and industries using it for power generation from small kW to hundreds of kWs Grid-tied solar PV systems are the most common systems used in captive power production in India. The use of diesel solar hybrids is growing; however, the growth in use of wind-solar hybrid systems has much slower than expected, owing primarily to performance issues with micro wind turbines It costs about Rs. 80,000-1,00,000 per kW for setting up a captive solar PV system without battery storage and about 30-50% more for a system with batteries depending on the hours of autonomy There are a number of established companies that can take up turnkey implementation of captive solar PV systems; in addition, there are dozens of small players operating in this market, with this number expected to increase dramatically in the near future The National Solar Mission has a special section of incentives for offgrid solar power production, with incentives in the form of capital subsidies. In addition, captive solar power plants can also avail accelerated depreciation benefits Set as a replacement for diesel power generation, captive solar PV power plants provide attractive equity IRRs and equity payback periods, under typical financing patterns Until now, the most preferred route for captive solar PV has been the corporate financing route.

According to an article [*.pdf] in the August issue of Microbiology Today , this technology has an added bonus: leftover enzymes can be used to scavenge precious metals from spent automotive catalysts to help make fuel cells that convert hydrogen into energy. Hydrogen has three times more potential energy by weight than petrol, making it the highest energy-content fuel available. Research into using bacteria to produce hydrogen from waste biomass has been revived thanks to the rising profile of energy issues. According to the researchers, the UK throws away a third of its food, wasting 7 million tonnes a year. The majority of this is currently sent to landfill where it produces gases like methane, which is a greenhouse gas 25 times more potent than carbon dioxide. Following some major advances in the technology used to make biohydrogen, this waste can now be turned into valuable energy. Two-stage process There are special and yet prevalent circumstances under which micro-organisms have no better way of gaining energy than to release hydrogen into their environment. Microbes such as heterotrophs, cyanobacteria, microalgae and purple bacteria all produce biohydrogen in different ways, says Dr Mark Redwood from the University of Birmingham. When there is no oxygen, fermentative bacteria use carbohydrates like sugar to produce hydrogen and
