论文摘要
可再生能源资源已广泛可用，但它们在全球范围内分布不均。在可再生的未来，缺乏高质量可再生资源的国家可能会选择从其他国家进口能源。为了评估全球可再生能源贸易的资源依赖性和技术经济基础，并确定潜在的进口商和出口商，本研究介绍了两个新的指标：可续签的级别水平化的能源（RLCOE_EX）（RLCOE_EX）和势能出口量（PEEV）。这些指标是根据区域资源潜力，国内能源需求和各个国家 /地区的财务成本变化计算的，而无需任何能源系统建模。通过将这两个指标应用于165个国家/地区，我们确定具有出口可再生能源（例如美国，中国）以及缺乏满足需求的国内资源的国家（例如，韩国，日本）。 RLCOE_EX和PEEV指标通过单独的分析进行了验证，该分析采用每个国家/地区的全面能源系统模型。
Renewable energy resources are widely available, yet they are unevenly distributed globally. In a renewable future, countries lacking high-quality renewable resources may choose to import energy from other countries. To assess the resource-dependent and techno-economic basis for global renewable energy trade and identify potential importers and exporters, this study introduces two new metrics: Renewable Levelized Cost of Energy available for Export (RLCOE_Ex) and Potential Energy Export Volume (PEEV). These metrics are computed based on regional resource potential, domestic energy demand and varying financial costs across countries, without the need for any energy system modeling. By applying these two metrics to 165 countries/regions, we identify countries with significant potential for exporting renewable energy (e.g., the US, China) and those that lack the domestic resources to satisfy demand (e.g., South Korea, Japan). The RLCOE_Ex and PEEV metrics are validated through a separate analysis, employing a comprehensive energy system model for each country/region.
