The decentralized revolution being ushered in by blockchain, an emerging technology with the potential to bring significant innovation and benefits, has also piqued the interest of major players in the energy supply industry, financial institutions, technology developers, academia, and national governments. How the deep integration of blockchain and energy will impact energy’s prospects and the energy market remains an open question. This study conducts a composite of qualitative and quantitative analyses of 622 selected articles on blockchain in the energy field. It is dedicated to identifying feasible technical paths and potential themes. The results show that (1) Research in this field follows two main approaches: engineering- and management-oriented. (2) Management-oriented research has become mainstream. (3) Research has led to new transaction systems, and the commercialization of energy blockchains has driven research iterations. Thematic predictions call for more attention to the negative impacts of technology, such as new business risks, the problem of lagging regulations, and the drawbacks of high energy consumption. This study provides research references and practical suggestions for researchers, regulators, and enterprises.

区块链这一新兴技术所带来的去中心化革命有可能带来重大创新和效益，也引起了能源供应行业、金融机构、技术开发商、学术界和国家政府主要参与者的兴趣。区块链与能源的深度融合将如何影响能源前景和能源市场仍然是一个悬而未决的问题。本研究对 622 篇精选的能源领域区块链文章进行了定性和定量分析。它致力于确定可行的技术路径和潜在主题。研究结果表明：（1）该领域的研究主要遵循工程导向和管理导向两种途径。(2)管理导向研究成为主流。（3）研究催生了新的交易系统，能源区块链的商业化驱动了研究迭代。专题预测呼吁更多关注技术带来的负面影响，如新业务风险、监管滞后问题、高能耗弊端等。本研究为研究者、监管者和企业提供研究参考和实践建议。
