能源区块链是一个基于区块链技术的平台，为点对点交易和自动化智能合约创建一个安全，透明和分散的系统。该平台能够促进能源资源的交换和管理，例如电力或可再生能源证书。我们的研究旨在阐明全球区块链技术能源系统的增长趋势。这项研究的新奇之处在于，使用专利分解分析和对数平均Divisia指数分析来了解能源区块链专利授予的主要因素，并发现研发从电力转向其他技术的相对重要性。此外，IPC能源区块链技术主要侧重于配置和管理能源系统，包括电力、天然气和供水。我们还全面概述了各国和公司如何参与能源区块链技术，并发现中国以59%的专利领先，其次是美国的20%，但他们的具体技术份额有所不同。参与者超越了传统的能源领域，包括电气和电子机械，IT公司，运输制造商，初创公司和致力于区块链技术的大学。
The energy blockchain is a platform based on blockchain technology, creating a secure, transparent, and decentralized system for peer-to-peer transactions and automated smart contracts. This platform has the ability to facilitate the exchange and management of energy resources, such as electricity or renewable energy certificates. Our research aims to clarify the growth trends of energy systems with blockchain technology throughout the world. The novelty of this study is to understand the main factor in energy blockchain patent granting using a patent decomposition analysis and log mean Divisia index analysis and discover the relative importance in the R&D shift from electricity to other technology. Additionally, the IPC for energy blockchain technology primarily focuses on configuring and managing energy systems, including electricity, gas, and water supply. We also present a comprehensive overview of how countries and companies engage with energy blockchain technology and find China leads with 59% of patents, followed by the U.S. with 20%, but their specific tech shares differ. Participants span beyond traditional energy sectors, including electric and electronic machinery, IT firms, transport manufacturers, startups, and universities dedicated to blockchain technology.
