Use of syngas for electrical power and heat production is more adaptable and direct as compared to its use for fuels and chemicals production. Several demonstrations of heat and power generation using syngas generated from biomass and wastes are available in literature (Young and Pian 2003; Bengtsson 2011; Son et al. 2011). Technologies used for heat and power productions include external combustion engines such as steam engine, internal combustion engines such as reciprocating gas engines and gas turbines and fuels cells. However, challenges remain in using existing equipment because of low volumetric energy content of biomass-generated syngas (4-15 MJ/m3) as compared to that of fossil fuels such as natural gas (38 MJ/m3) (Wang et al. 2008), for which the engines are designed for. Use of gas turbines was demonstrated in a week-long tests for power production from wood chips-generated syngas in Sweden at the scale of 18 MW (thermal) (Bengtsson 2011). In developing countries, gasification of locally available biomass and wastes has potential to provide electricity (Abe et al.

2007) . However, the challenges in commercialization of biomass gasification for power generation are several: robust syngas cleaning technologies are needed; power is lower value product than liquid fuels; and infrastructure and equipment to use biomass is not well-established unlike fossil-based feedstocks such as coal and natural gas.
