Wide Range

Trees and other forms of vegetation are well designed for the collection and storage of solar energy. Moreover, photosynthetic organisms show enormous diversity and are well adapted for a wide range of environments. Biomass is convertible to liquid and gaseous fuels by a number of established processes, and this paper examines the possible contribution of biomass to world energy demands. The maximum efficiency of solar energy conversion in plant production is 5-6 %, but plants grown under usual field conditions do not achieve this degree of conversion. The highest yielding crops convert solar energy into plant material with an efficiency of 1-2%, but the average yields of the major crops and forests indicate considerably lower efficiencies. The average efficiency of solar energy conversion on a global scale is estimated as about 0.15 %. The energy content of the annual biomass residues in Australia and U.S.A. is equal to about one-quarter of the primary energy use in those countries, but only about one-third of the residues are considered to be readily recoverable. A number of high yielding crops are examined as potential fuel crops. Energy inputs for growing non-irrigated crops in Australia are estimated to amount to 7-17 % of the solar energy stored in the total crop biomass. Irrigation adds considerably to the energy cost of producing crops. The overall energy efficiency of fuel production from biomass varies from 20 to 58%, depending on the nature of the biomass and the process used to produce liquid or gaseous fuel. A recent estimate by an Australian committee of the potential contribution of biomass to liquid fuel production in Australia is presented. It is concluded that biomass will not be able to provide a substantial fraction of the world’s energy demand, although it can make a useful contribution.

The kinetic model has been developed for disserting the efficiency of solar energy conversion as a function of light intensity. A comparison of theory with experimental results shows that the model provides a satisfactory agreement. We have estimated the essential parameters of photosynthetic systems (the size of the photosynthetic antenna, the rate of electron transport, the correlation between photosynthesis and respiration) that are responsible for reaching the maximum efficiency at "one sun" and "one hundred suns" light illumination intensities. Recommendations for the improvement of photosynthetic system parameters using genetic engineering methods are also provided.
