📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本はSBSPの研究開発を進めており、エネルギー安全保障と技術リーダーシップの観点から関連性がある。ただし、現行のGX政策（GX推進戦略やSSBJ開示）との直接的な連携は薄く、長期的な技術開発戦略として位置づけられる。
In the global GX context
Globally, SBSP is gaining attention as a clean energy source, with programs in the US, China, Japan, and Europe. This paper contributes to the discourse on energy transition and space economy, offering a comparative framework that can inform international cooperation and competition in clean energy technology.
👥 読者別の含意
🔬研究者:Provides a novel application of LCOE to space-based solar projects and a classification of national strategies, useful for energy economics and policy research.
🏢実務担当者:Offers insights into long-term investment opportunities in space energy, but practical applicability for corporate sustainability teams is limited.
🏛政策担当者:Highlights the strategic importance of SBSP for energy security and technological leadership, informing national energy and space policy.
📄 Abstract（原文）
The development of space-based solar energy (SBSP) in the last decade goes beyond scientific and technical experiments and acquires the features of an emerging sector of the global economy. In contrast to the works focused on technological aspects or the environmental agenda, the study considers SBSP as an area of intersection of long-term investment strategies, national priorities of energy security and new market opportunities. The subject of the analysis is the country models of SBSP development, their institutional design and economic parameters determining the prospects for the orbital stations’ commercialization. The purpose of the work is to identify the dominant national strategies in the sphere of space energy and to determine the threshold values of indicators ensuring its economic feasibility. The relevance of the topic is due to the intensification of programs in the United States, China, Japan, India, Russia and the European Union, which consider SBSP as a tool for reducing dependence on traditional energy carriers and consolidating technological leadership. The methodological framework includes comparative country analysis, modeling with the decomposition of factor influences on LCOE, as well as analysis of strategic documents and reporting data. The scientific novelty of the study lies in the classification of national approaches to the development of CSE, built on the basis of the analysis of financing sources and mechanisms, as well as in the adaptation of the levelized cost of energy (LCOE) methodology to the specifics of space projects. The results of the study allow us to identify six strategic paradigms, from the American synergetic model based on private initiative to the conservative evolutionary position of Russia. Quantitative analysis confirms the main barrier to commercialization is not the efficiency of photovoltaic cells but the cost of launching a payload into orbit, setting benchmarks for long-term investment policy and technological development.
