Renewable energy has been rapidly used in the last 20 years for the great reduction of CO₂ emission into the atmosphere and the development of sustainable society. In this presentation, the following issues regarding biomass power generation systems are summarized: (1) many restrictions of biomass power generation systems such as (1-1) very low energy efficiency from solar power to electricity, (1-2) limiting amount of resource, and (1-3) requirement of fuel cost for operation, and (2) characteristics of combustion technologies including drawbacks and the following strong points: (2-1) high power, (2-2) high-temperature heat generation, and (2-3) utilization for hygiene or sanitation purposes. and I propose 3) next-generation biomass power generation systems integrated with variable renewable energy (VRE) and energy storage system for dynamic operation are proposed as a promising method to balance the intermittent electricity supply by VRE and electricity demands. The reduction of simple combustion and the noble use of combustion technology by effectively utilizing these strongpoints are needed to greatly reduce CO₂ emission even if renewable biomass is used
