摘要: 化石燃料的日渐枯竭以及因CO2气体排放引起的全球气候变暖等问题日益引起人们的重视.寻找更高效、安全且价廉的电化学储电和发电装置是关键.利用弃风、弃光等可再生能源的电能,以高温熔盐为电解质,将氧化物转化为可再生燃料,即电能转化为化学能技术已成为近几年氧化物特别是CO2固定和资源化技术的研究热点;同时,通过熔融盐基燃料电池技术将可再生燃料中化学能转化为电能,具有高效、清洁且燃料范围广泛的优点.本文将围绕季节储能和区域储能的需要,主要阐述通过熔盐电化学方法实现可再生燃料的制备-利用技术的可行性和初期研究结果,主要包括氧化物转化为可再生燃料、可再生燃料转化电能(直接固体燃料电池)以及可逆的直接固体燃料电池三个方面.

Abstract: The ever-increasing consumption of finite resources of fossil fuels and global environmental concerns have accelerated the efforts to develop efficient and affordable electrochemical energy storage and electricity generation devices. Electrochemical reduction of oxides to fuels in molten salts using renewable energy sources such as solar and wind power is an effective way for converting electrical energy to chemical energy in fuel itself; this energy can be converted back to electricity when the fuel is electrochemically re-oxidized in fuel cells. These processes can be related with the molten salts enabled electrochemical cycling between oxides and solid fuels. Because solid fuels are of high density and stable in air, they are suitable for long term storage and long distance transportation. Therefore, we anticipate that the realization of "seasonal energy storage" (SES) and "regional energy storage" (RES). The purpose of SES is to store energy harvested in the sunny summer and reuse it in cold winter, whilst the RES aims to collect energy from remote desserts (sunlight to electricity) or mountains (wind to electricity) to urban areas. Preparation and application of the regenerative fuels via electrochemical process in molten salts are discussed.
