计及管道输氢成本的绿色甲烷生产单元技术经济性评估
Techno-economic evaluation of green methane production units considering the cost of hydrogen pipeline transportation
摘要
Abstract
The green methane production unit(GMPU),based on coupling green hydrogen from renewable electricity and carbon capture in coal-fired power plants,can effectively promote renewable energy utilization and reduce carbon emissions.However,China's renewable energy resources are geographically mismatched with both the carbon emission-intensive coal-fired power plants and the natural gas load centers,requiring long-distance hydrogen pipelines for transportation.To quantitatively assess the levelized cost of gas(LCOG),a system model of GMPU is developed.A techno-economic evaluation model,incorporating invest-ment and operational costs of each subsystem,is established to compare LCOG with and without considering hydrogen transport costs.The results show that,ignoring transport costs,LCOG of GMPU with an annual out-put of 28 000 t of green methane is 9.18 yuan/m3.When the hydrogen transport distance is 300 km,LCOG in-creases by 0.639 yuan/m3,with the transport cost accounting for 6.50%of the total.In the construction of long-distance hydrogen pipelines,the pipeline length should be reasonably planned based on the maximum pressure drop to avoid significant cost increases.关键词
