Design and Performance Analysis of a Clean Energy Installation for Residential Use

摘要

Two of the primary energy demands of residential customers are electricity and fuel for road transport. The ideal solution would be to address those necessities using renewable resources. To accomplish this goal, various green technologies have already been developed to supply electricity. From the point of view of road transport, hydrogen is a clean energy source that is more efficient than other fossil fuels used to date. However, its use in this field is still limited, not only because of technical and economic limitations of the vehicle itself but also due to the need for large hydrogen refuelling stations. For that reason, the primary objective of this paper is to present the design and performance of a residential hydrogen fuelling station based on water electrolysis. To obtain more complete and efficient performance, the design has been developed to take into consideration the power consumption of the residence itself. In addition, also the power surplus will be sold to the electrical grid to help recover the investment. The option selected for producing the required power and hydrogen is wind energy, due to the favourable characteristics of efficiency, reliability, cost and safety of this resource. Moreover, an analysis of the performance of the designed installation has been evaluated through a simulation with Matlab/Sim Power System. An estimation of the costs has also been developed.
