Abstract

In accordance with the New and Renewable Energy Supply Statistics, biomass power generation has surged since 2013, and use of wood pellet has the most sharply increased, 696Gwh in 2013, 2,764Gwh in 2014 and 2,512Gwh in 2015. Total domestic wood pellet consumption was 1.48million tons in 2015, of which wood pellets consumed for power generation account for about 1.08million tons, about 73%. In this study, we gained the result that the wood pellet would be consumed 2.61million tons in 2020, 6.85million tons in 2025, 11.39million tons in 2030. We also calculated the optimum biomass power generation, on the premise that the power plant co-fire 50% biomass, and the result was that 2.26million tons of wood pellets should be produced domestically in 2021 to operate the present licensed wood pellet power plant from this study.

신 재생에너지 보급통계에 의하면 바이오매스 발전실적은 2013년 부터 급증하고 있으며 그 중에서 가장 급격하게 증가한 연료는 Wood pellet으로 2013년 696Gwh, 2014년 2,764Gwh, 2015년에는 2,512Gwh를 발전 하였고 국내 Wood pellet 총 소비량은 2015년 기준 148만톤이며 그 중 발전용으로 소비된 Wood pellet은 108만톤으로 약 73%를 차지하고 있다. 본 연구에서 Wood pellet 소요량을 예측한 결과 국내 발전용으로 필요한 Wood pellet 소요량은 2020년 261만톤, 2025년 685만톤, 2030년 1,139만톤이 필요하며, 최적 바이오매스 발전량 산정을 위하여 바이오매스 발전소에서 국내 생산 Wood pellet 사용량을 50% 사용한다는 가정하에 기 허가 신청된 발전소를 가동하기 위해서는 2021년 226만톤의 Wood pellet이 국내에서 생산되어야 한다는 결론이 도출 되었다.
