    Advances in manufacturing technologies and materials are crucial to the commercial deployment of energy technologies. We present the case of concentrating solar power (CSP) with molten salt (MS) thermal storage, where low-cost, high-efficiency heat exchangers (HXs) are needed to achieve cost competitiveness. The materials required to tolerate the extreme operating conditions in CSP systems make it difficult or infeasible to produce them using conventional ... ...点击完成人机验证后继续浏览

    制造业技术和材料的进步对于能源技术的商业化部署至关重要。本文以熔盐(MS)储能的聚光太阳能发电(CSP)为例,介绍了为了实现成本竞争力所需的低成本、高效率换热器(HX)。由于CSP系统中极端运行条件所需材料难以用传统制造工艺生产,尽管可以通过选择性激光粉末床融合(LPBF)等增材制造技术生产性能合适的换热器,但本文评估了采用这种方法是否具有成本效益。我们描述了一种基于过程的成本模型(PBCM),用于估算使用LPBF制造MS至超临界二氧化碳换热器的成本。该PBCM旨在识别对制造成本影响最大的设计修改、工艺选择和制造业创新。我们的PBCM确定了可以将预期的HX成本从每千瓦热量750美元(8元/立方厘米)降低到当前可用LPBF技术下的350美元/kW-th(6元/立方厘米),并且通过短期内可能实现的LPBF技术改进,进一步降低成本至220美元/kW-th(4元/立方厘米)。此外,PBCM还指导了一个HX设计的重新设计,将预期成本降低到140-160美元/kW-th(3元/立方厘米)。
