As shown in Table , oil extraction phase is the major contributor of life cycle environmental impacts of B100 fuel, and majority of the impacts in oil extraction phase are due to the use of electricity from Indian power grid. Indian power grid is presently dominated by fossil feedstocks (~80%) with renewable having less (~20%) share in grid electricity . In near future, it is expected that renewable will have significant share in electricity generation so that the environmental impacts intensity of power grid will reduce, so we assume three scenarios: base case scenario (Scenario 1), 15% reduction in grid intensity (Scenario 2), 30% reduction in grid intensity (Scenario 3). It is observed that for scenario 2, global warming potential will be reduced by 4.3% over base case scenario and compared to the reference fuel diesel reduction in GWP impact category will increase from 59.6% to 61.4%. Significant reduction is expected in acidification potential (~8.8%) and human toxicity potential impact category (~12.6%) from the base case under scenario 2. For scenario 3, global warming potential will reduce by 9% over base case scenario (% saving in GWP over reference fuel diesel will increase from 59.6% to 63.1% over base case). Similarly, acidification potential, human toxicity potential, and eutrophication potential will decrease by 19.4%, 28.8%, and 6.53% respectively from the base case scenario (Table ).
