Fuel cell-based hybrid cycles that include conventional power generators have been created to modify energy performance and output power. In the present paper, integrated biomass gasification (IBG)-molten carbonate fuel cell (MCFC)-gas turbine (GT) and steam turbine (ST) combined power cycle is introduced as an innovative technique in terms of sustainable energy. In addition, biomass gasificati...

The study deals with an emergy evaluation of the supply of electricity and heat to a large user, namely a public hospital in Northern Italy. We performed firstly a conventional LCA evaluation, in order to identify and quantify the material and energy flows involved in three cogeneration alternatives for the hospital. The evaluated cogeneration alternatives were: 1) an Internal Combustion Engine...

1.1 Background Thanks to the breakthroughs in microfabrication technologies, numerous concepts of microsystems including micro aerial vehicles, microbots, and nanosatellites have been proposed. Contrary to ordinary electronic devices, these microsystems perform mechanical work and require the extended operation. As their functions are getting complex and advanced, their energy consumption is al...

The molten carbonate fuel cell (MCFC) has evolved to current megawatt-scale commercial power plants. When using the fuel cell for electrolysis (MCEC), it provides a promising option for producing fuel gases such as hydrogen, via water electrolysis, and syngas, via co-electrolysis of water and carbon dioxide. The molten carbonate cell can thereby operate reversibly as a dual energy converter for...

•Wind-electrolysis hydrogen fuel cells have the largest CO2 mitigation potential•CO2, PM2.5, and SO2 potentials of different trajectories are estimated•Fuel reduce over 70% emissions from coal-fired power plants•Deploying in northern China enables environmental benefits has committed to reaching carbon neutrality by 2060. One challenges country faces is a transition away emission-intensive ener...

Continuous depletion of the crude oil and gradual increase in the oil price have emphasized the need of a suitable alternative to our century-old oil-based economy. A clean and efficient power supply device based on a renewable energy source has to be available to face this issue. Among the different technological alternatives, fuel cell power generation becomes a more and more interesting and ...
