Enabling Support Tool (EST)

How much would it cost to Decarbonise your bus fleet?

This tool is aimed at bus operators that are looking to decarbonise their fleet. If you have been thinking of the viability of hydrogen compared to alternative fuels, this will help you decide.

Total Cost of Ownership & Abatement (TCO/TCA)

The model will supply the TCO & TCA for transitioning to a hydrogen based fleet. As well as compare the viability of hydrogen to battery electric and traditional diesel methods.

Use EST results to begin your Decarbonisation process

The model aims to give you a base estimate of how viable it is for your bus fleet to switch to hydrogen based operations. Using the model outputs you can see which routes would be ideal for hydrogen use.

What do you need to complete the EST?

To complete the EST, you are required to input some general information about your bus fleet such as fleet size, operational time, and data on your routes. There are external links to help you complete some of the sections about degree days and the steepness of your routes, which will help the model compare hydrogen busses to their battery electric counterparts. Take time to follow the instructions on each section to get the most accurate information for the model. 

Some concepts that are necesary to understand are the UA value of your fleet, and the Utilisation rate of your busses along route:

(Explanation here)

You may go back and forth through the form, and complete it as many times as you would like. Feel free to pre-check the form for what information is required. If there is any information which you do not have available, the model will input a default value based on our calculated assumptions. However, this will make the model less accurate for your fleet transition.

At the end of the form you will be presented with charts such as the example on the right. This displays the TCO & TCA of the bus fleet based of the information provided. This is for each route and compares the fuel types of Hydrogen, battery electric and traditional diesel drive trains.
