Abstract:
This paper examines four concepts for resilient energy supply on construction sites. It focuses on possible applications of renewable energies and alternative low-emission technologies. Hydrogen technology plays a central role in this context. The supply of generative energies is considered using the example of a model construction site, and conclusions are drawn about its feasibility. A methodology is used to evaluate different variants in terms of economic efficiency and environmental friendliness with the aid of a cost-effectiveness analysis. In addition, the impact of a CO2 shadow price model on the advantages of the design alternatives in the concept is examined and the CO2 price of the turning point is determined, where environmentally friendly alternatives are the preferred variants. A PV system proves to be advantageous but can only partially cover energy needs. Electricity generators with fuel cells and electric excavators are associated with very high costs and limited performance.
