1. Introduction

The European Union promotes the transition to a sustainable energy system

based on energy efficiency, alternative fuels and renewable energy sources.

This means that there are mainly three fields of action regarding the PCT

equipment:

• Use of more efficient energy systems

• Reduction of fossil fuel based equipment

• Use of energy recovery systems


1. Introduction

What will do GREENCRANES on this matter?

Activity 2. Evaluation of Eco-Efficient GREENCRANES Alternatives.

Activity 2 will develop an integral evaluation with the aim of adapting existing

solutions based on innovative low-carbon emission technologies and alternative

fuels for PCTs equipment and handling machinery. The adoption of these

technologies would significantly reduce the global carbon footprint of port

container facilities.

In GREENCRANES, the methodology for the evaluation and selection of PCTs Eco-

Efficient Alternatives has been designed according to technical, environmental

and economical criteria. Although the three mentioned requirements need to be

satisfied in order to make viable the implementation of certain alternative, the

critical criterion is associated to the cost-benefit result of the investment.

To check the economical feasibility, GREENCRANES is developing an approach

based on the modelling and simulation of the considered eco-efficient

alternatives which were feasible from the technical and environmental

perspectives. The methodology for this evaluation is based on the concept of

differential investment modelling.



The differential investment model calculates the cash-flow (positive or negative)

generated by the new alternative and provides as outputs three investment

variables: Net Present Value (NPV), Internal Rate of Return (IRR) and Investment

Payback (IP).

Net Present Value (€) Internal Rate of Return (%) Investment Payback (years)



The GREENCRANES has developed two differential Investment Models:

• Single-variable model: the investment takes place exclusively over a

machine/vehicle (e.g., substitution of TT, RS, etc). This model is based on the

differential of energy consumption between two alternatives.

• Two-variable model: requires investments over a machine/crane/vehicle

and also over a certain area of the installation (e.g., electrification of RTGs).

Both models analyze a combination of scenarios and generate as outputs a

distribution of solutions. The single-variable model gives a linear distribution for

the reference output variables (NPV, IRR and IP). And in two-variable model, the

distribution is composed by a surface, combination of the different scenarios for

the two analyzed investment variables.



In both cases the OPTIMUM is reached in a combination of solutions which

maximizes NPV or IRR.
