Hydrogen energy is clean, and its use leads to a reduction of CO2 emissions into the atmosphere. It represents an alternative to traditional fuels, oil, coal, and gas. The use of hydrogen preserves traditional fuel resources. In the field of comfort, the energy obtained from hydrogen is applicable in the heating and air conditioning of spaces, in the production of electricity necessary to create light comfort. The use of hydrogen in boilers leads to the reduction of pollutant emissions. Hydrogen fuelling systems were designed for different experimental thermal machines, designed by authors from spark-ignition engine and compression ignition engine. The characteristic combustion parameters, like maximum pressure, the maximum rate of pressure rise, efficiency, and pollutant emissions for hydrogen fuelling are presented and analyzed.","PeriodicalId":231315,"journal":{"name":"Hydrogen Fuel Cell Technology for Stationary Applications","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114465097","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}

For many people, the term energy storage is the storage of electricity in batteries, as it is the most commonly found way of storing energy. In addition to classic batteries, there are other energy storage alternatives from a primary source for later use. The most valuable forms of energy storage are the ones that can both take over and release the energy on demand, in the form of electricity, such that, in the end, the electrical energy is transformed into thermal or mechanical energy. In stationary applications, energy can be stored in various forms such as batteries, ultracapacitors, or tanks of hydrogen, water, and different types of materials. This chapter will evaluate each form of energy storage.","PeriodicalId":231315,"journal":{"name":"Hydrogen Fuel Cell Technology for Stationary Applications","volume":"12 1-4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114080500","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}
