In this study, the life cycle costs of railway projects involving hybrid diesel-electric vehicles are analysed. Specifically, analysis focuses on comparison 3 lithium-ion battery technologies (NMC, LTO and LFP) 8 energy management strategies (including rule-based optimization-based strategies). order to develop analysis, a methodology that returns cost each proposed case is presented. The inclu...

Heterotrophic or autotrophic? This is the continuous question industry faces when microalgae production endeavor. Surprisingly, nowadays specialists have not reached a consensus on which most economical option. The current work analyses costs for heterotrophic and autotrophic cultivation of at an industrial scale. results in cost 4.00 €·kg −1 dry weight as centrifuged paste. within range costs,...

In small-scale hydropower scheme, the most important component is electro-mechanical equipment. Since cost contribution of this component is high because hydrokinetic projects require negligible civil works. Turbine and alternator contribute a major fraction of the hydrokinetic projects. Thus, there is a requirement to estimates the electromechanical equipment cost for a hydrokinetic hydropower...

Decentralized Generation (DG) is expected to play a vital role in the future of electric power system. The power electronics interfaced microturbine generation systems are currently attracting lot of attention to meet different needs both at end consumers and the distribution utility levels. Dynamic modelling of the microturbine is a challenging process because manufacturers do not readily prov...

This paper presents the theoretical foundations of an intelligent online modelling tool capable of processing heterogeneous information on complex techno-economical systems. Its main functionality is to investigate, elicit, and apply rules and principles that govern the development processes of technologies and related markets. Specifically, we will focus on applications of the tool to model th...
