能源互联网推动下的氢能发展

Hydrogen energy development driven by the Energy Internet

随着当前以化石燃料为主的能源体系资源消耗和环境污染问题日益严重,能源结构转型已经成为世界能源体系发展的重要趋势。能源互联网是以信息传递为基础,以可再生能源和核能为主要一次能源供体,以电能为核心,以储能技术为媒介的新型能源体系,具有智能化、清洁化、操作灵活化等优点,是未来能源结构发展的理想形式。氢能具有热值高、无污染、可再生、长周期储存和远距离运输等优点,能够实现“可再生能源-电能-氢能”的多样化转换,可作为能量储存、传递和转换媒介在能源互联网构建中发挥重要作用。该文从能源互联网的概念出发,阐述了氢能在能源互联网中的重要地位,并结合清华大学核能与新能源技术研究院(简称核研院)在核能制氢方面的研究成果,综述了氢能和氢储能技术在能源互联网体系下的关键技术的发展现状,并对氢储能技术的未来发展做出展望。

The increasing resource consumption and environmental pollution in the current energy supply system dominated by fossil fuels is leading to a transformation of the energy structure of the world's energy supply.The Energy Internet is a new energy system based on information transmission,with renewable energy and nuclear energy as the primary energy supplies,with electrical energy as the core,and extensive energy storage.This ideal,future energy structure has the advantages of intellectualization,cleanliness,flexibility and others.Hydrogen is a secondary energy carrier with high caloric value,no pollution when burned,good long-term storage potential and easy long-distance transport.Thus,hydrogen will play a vital role in the Energy Internet as a energy storage,transmission and conversion medium.This article describes the importance of hydrogen in the future Energy Internet.In addition,this article relates recent progress in hydrogen production from nuclear energy in the Institute of Nuclear and New Energy Technology(INET),Tsinghua University,to the current status of the development of key technologies for hydrogen and its storage in the Energy Internet system along with future development prospects for hydrogen storage technologies.
