“…Other than the energetic and environmental performance, the principal benefit of using a CHP system is economic, either through saved fuel costs [13] or through fiscal incentive schemes such as electricity feed-in tariffs (FIT) [14,15]. Various case studies have shown that savings created over the lifetime of such systems are enough to offset the total lifetime operating cost, including capital costs, running costs, and maintenance costs, and leave enough profitable margin to invest in the system [16][17][18][19].…”

In Europe, the energy consumed for heating and cooling purposes by the hospitality sector is significant. In island economies such as that of the Mediterranean Island of Malta, where Tourism is considered essential to the local economy, energy consumption is perhaps even more significant, and energy-efficient systems, or the use of renewable energy, are often listed as possible solutions to counter this. Based on this premise, the research contained in this paper presents an investigation on the technical and financial feasibility of using Combined Heat and Power (CHP) and Combined Cooling, Heating, and Power (CCHP) systems for the hospitality sector in Malta. Using a supply–demand design methodology, the research made use of the software package RETScreen to model the electrical and thermal demand of a number of hotels ranging from 3- to 5-star hotels. Based on these modelled hotels, different scenarios were simulated to analyze the technical and financial implications of installing a CHP in these modelled hotels. A number of parameters, including thermal size matching, presence of financial grants, electricity tariffs, feed-in tariffs, and fuel prices, were tested out for a total of 144 scenarios. Results showed that the parameters having the highest impact were those of a financial nature. Specifically, the study showed that the 4-star hotels considered were the hotels which would benefit the most from having such systems installed.

“…The majority (82%) of the total primary energy demand in the EU residential sector is consumed for space heating and hot water supply [4,5]. In line with the goals of the European Union of "improving energy efficiency" by 27% in 2030 and "reducing greenhouse gas emissions" by 40% in 2030 compared to 1991, the minimum efficiency requirements within the Ecodesign legislative framework and the EU Energy Label [6][7][8] have proven to be effective. Another effective tool of eco-design, which has been gaining importance in recent years, is life cycle assessment (LCA), which allows for the quantitative assessment of the life cycle environmental performance of products and can be used by manufacturers and developers to design more sustainable and energy-efficient products, as well as by the government to support decision-making for legislation [9].…”

The energy demand of private households contributes globally to 36.5% of the total CO2 emissions. To analyze the emissions reduction potential, we conducted a comparative life cycle assessment of a proton exchange membrane fuel cell in a residential application and a conventional system with a stand-alone gas condensing boiler and electricity from a grid mix. The period under review was referred to as the service life of the PEMFC and is assumed to be 10 years (83,038 h of PEMFC). The applicability of this in a single-family house built between 1991 and 2000 under German climatic conditions was investigated. The functional unit is set to the thermal energy demand of 16,244 kWh/a and electricity demand of 4919 kWh/a of a single-family house. The impact assessment method “CML 2001–August 2016” was used in this investigation. The manufacturing phase of the proton exchange membrane fuel cell showed disadvantages, whereby the use phase had significant advantages in most of the environmental impact categories as compared to the conventional energy supply system. Considering the whole life cycle, the advantages from the use phase could outperform the disadvantages from the manufacturing phase in most of the impact categories, except for ADP elements and TETP.

“…Therefore, the demand for stationary fuel cell systems for buildings is increasing worldwide. Also, the electricity output, durability, system size, operation, installation, and operation costs of fuel cell systems are becoming competitive [5,6]. In particular, the efficiency of a fuel processor and fuel cell combined system is mainly affected by the fuel processor efficiency [7,8].…”

To increase the efficiency of a fuel processor and HT-PEMFC (high temperature-proton exchange membrane fuel cell) combined system, it is essential to improve the efficiency of the fuel processor. In this research, the fuel processor was simulated by the Aspen Hysys® simulator, and the effect of the various operating conditions on the total efficiency was investigated. The thermal efficiency of the fuel processor increased as the temperature and S/C (steam-to-carbon) ratio increased, and the efficiency was higher at an S/C ratio of 3 than at an S/C of 4 with a reformer temperature of 700 °C and higher. Under the selected operating conditions of the fuel processor, the recycling of unreacted hydrogen from the anode off-gas (AOG) of the HT-PEMFC improved the overall efficiency of the combined fuel processor and HT-PEMFC by a factor of 1.28. The operating conditions where the AOG supplied more heat than was required for fuel processor operation were excluded. The high-efficiency operating conditions of the fuel cell system were proposed with the target of 5 kW of output as the capacity of the household HT-PEMFC.
