NON-CONVENTIONAL ENERGY/RENEWABLE ENERGY
NGRI and NIO along with industry had undertaken preliminary assessment of hydrate potential in the offshore areas of India. For the first time multidisciplinary database of gas hydrates was created in the country at NIO. The favorable results obtained led to the formation of a National Gas Hydrate Programme (NGHP) under the Petroleum Ministry, Government of India, with the participation of the Oil industry. NIO has recently undertaken multidisciplinary investigations for the first time to decipher the proxies related to the occurrence of gas hydrates in the two selected modal laboratories in Krishna-Godavari (KG) offshore and Goa offshore on the East and West coasts of India, respectively. NGRI is involved in demarcating zones for gas hydrates along western continental margin using seismic methods, for Gas Authority of India. By undertaking the mega venture of gas hydrate exploration programme, NIO has become an active partner under NGHP (National Gas Hydrate Programme, conceived by the Ministry of Petroleum & Natural Gas, Government of India) with Oil industry (ONGC, GAIL, OIL and DGH).
Jatropha curcas, Salvadora, Pongamia and Madhuca indica are the some plants whose oil, though available in substantial quantities cannot be used for edible purposes. IIP aims to develop processes for using such oils into bio-diesel under a sponsored project from Department of Biotechnology (DBT). The study would include characterization of biodiesel and engine evaluation of its blends with diesel to study its beneficial effects. Another sponsored activity in this area is based on production of biodiesel from totally renewable resources using Jatropha curcas oil and ethanol. This study includes field trials of biodiesel blends in passenger cars apart engine evaluation. This is a collaborative study of IIP/CSIR and MNES
IIP is also working on the production of lubricants and speciality products such as transfer oil, hydraulic oils, etc., from vegetable oils and cellulosic and starchy materials.
CSMCRI has taken up an international collaborative R&D project with Daimler Chrysler and University of Hoheinhem, Germany on Jatropha curcas.
NBRI is involved in the development of biofuels and has completed network projects on Guayule, hydrocarbon crops, non-edible vegetable oil crops, etc. It participates in a mission programme of DBT for developing techniques and technologies on bio-fuel cultivation, extraction and processing. It is promoting bio-diesel from Jatropha curcas, Madhuca sp., Pongamia pinnata and Salvadora sp, as well as working with Biotech Park for producing large number of Jatropha curcas seedlings. Under a Biomass Research Center Programme financed by MNES, it has developed protocols, selected elites, produced large-scale quality seedlings and information about plantation of energy plants and bio-fuel species. It has developed hi-tech, low-cost nurseries for clonal propagation of bio-fuel tees and shrubs.
Liquid fuels from petro-crops
IIP has worked on the development of energy crops for liquid fuels since 1979 under the sponsorship of DST and later Ministry of Non-Conventional Energy Source. Laticiferous and resinous species have been screened for their potential as energy crops. These studies resulted in the identification of E. antisphilitica as the species with most potential having maximum bio-crude yield 8.8 per cent on dry weight basis.
The aim of the present study under the DBT sponsored project is to (i) evaluate the potential of hydrocarbons from energy crops, (ii) develop the extraction technology of bio-crude and (iii) conversion of bio-crude to liquid fuels by catalytic and thermal cracking.
IIP is also working on the development of high-performance lubricity oil using vegetable oils derived esters and synthetic esters.
Liquid fuels from petrocrops/biomass
IIP is pursuing R&D work on ethanol production and liquid fuels from pyrolysis under CSIR Network project to develop cost effective processes utilising indigenous resources.
The production of hydrogen from biomass, a renewable source, rather than the conventional process of hydrogen production from fossil fuels is the process of the future. IIP has taken up the project to study the process of hydrogen production from biomass as a part of NMITLI project on hydrogen production for fuel cells.

The coal industry is facing serious problems in the supply of good quality coal both for metallurgical and power industries. Keeping this in mind future activities would focus on characterization and washability studies on coking and non-coking coals from different coalfields. With increased focus on planned utilization of mineral resources coupled with environmental consideration, there is an urgent need for utilization of low-grade resources as well as off-grade rejects. With depletion of high-grade resources and increased complexity of lean ores, continuous pursuit of finding economically feasible process is the need of the hour. Proper utilization of the fines generated from mining and processing may certainly prove beneficial towards conservation of natural resources as well as reduction of environmental related problems.
High sulphur content in lignite/coals present problems in their utilization as fuel. Although biochemical and chemical desulphurisation routes have been traced, these are not entirely successful. Thus the endeavour would be to utilize such high sulfur hydrocarbon and develop a cost effective process for conversion of high sulphur inferior lignite into low sulphur superior fuel char to be used in cement plants and in fluidized bed reactors and to reduce the sulphur content of the high- sulphur Assam coals to enable their use in any of the heat and power generating industries.
Coal characterization in terms of its alpha quartz content, mercury and other trace elements, besides ash properties is important for its efficient and clean utilization. Major emphasis in the coming years would be to address the problem of augmentation of coking coal through incorporation of hitherto non-linked coals and identification of new resources of non-coking coals.
The major activity in the coming years visualizes CFRI as the primary source and repository of data on all indigenous coals.
IIP would focus on new generation fuels and lubricants, upgradation and development of refining processes for heavier and high- sulphur crudes, alternative fuels like the conversion of biomass to fuels, biodiesel, conversation and utilization of natural gas including methane value chains, and biodegradable lubricants. There is a lot of scope for improved biomass gasification system for thermal applications and development of an ultrasonically aided anaerobic reactor for biomethanation of agricultural/ vegetable wastes as well as programmes on solar drying of kendu leaves, timber etc.
Fuel cells provide an exciting option for the efficient conversion of the energy into electricity and attention would be paid to this emerging area.
