A concept of an Active Carbon Neutral Energy System (ACRES) was proposed. Carbon dioxide is regenerated artificially into hydrocarbons by using a heat source with non-carbon dioxide emission, and the regenerated hydrocarbon is re-used cyclically as an energy carrier media in ACRES. Feasibility of ACRES was examined thermodynamically in comparison with hydrogen energy system. Carbon monoxide was the most suitable for a recycle carbon media in ACRES because of relatively high energy density in comparison with hydrogen, and high acceptability to conventional chemical, steel and high-temperature manufacturing industries. A high-temperature gas reactor was a good power source for ACRES. ACRES with carbon monoxide as recycle media was expected to be one of the efficient energy utilisation systems for the reactor.","PeriodicalId":88069,"journal":{"name":"Nuclear science abstracts","volume":"31 1","pages":"345-352"},"PeriodicalIF":0.0,"publicationDate":"2010-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77927563","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To minimise the cost of electricity, these plants must operate at maximum capacity; however, the electrical outputs do not match changing electricity demands with time. A system to produce intermediate and peak electricity is described that uses light water reactors (LWR) and high temperature electrolysis. At times of low electricity demand the LWR provides steam and electricity to a high temperature steam electrolysis system to produce hydrogen and oxygen that are stored. At times of high electricity demand, the reactor produces electricity for the electrical grid. Additional peak electricity is produced by combining the hydrogen and oxygen by operating the high temperature electrolysis units in reverse as fuel cells or using an oxy-hydrogen steam cycle. The storage and use of hydrogen and oxygen for intermediate and peak power production reduces the capital cost, increases the efficiency of the peak power production systems, and enables nuclear energy to be used to meet daily, weekly and seasonal changes in electrical demand. The economic viability is based on the higher electricity prices paid for peak-load electricity.","PeriodicalId":88069,"journal":{"name":"Nuclear science abstracts","volume":"23 1","pages":"155-164"},"PeriodicalIF":0.0,"publicationDate":"2010-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76078583","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
