Create a Pathway

Create a Pathway

In order to create a pathway in GREET.net it is necessary to know :

• What Processes are involved in the pathway, they can be either stationary or transportation processes
• What Resources, Intermediate Materials or Energies involved in the pathway

Once this is know we are going to check first that the database contains the necessary information for the resources and intermediate materials. If some are missing they will be added using the Resource Editor. In a second time the processes will be created. When the processes are all defined in the database the pathway can be build by assembling processes together.

Define Resources

See more details for Resources Editor

In order to link all the processes together, resources and products for each of them needs to be entered in the database. Usually we define a name and some physical properties if they apply like heating values or carbon and sulfur ratios. Those resources will be used to define the Inputs of a process and their Products. A simple example could be a coal electric plant which uses Coal as an input and produces Electricity. Coal and Electricity needs to be defined in our resources database.

Note : as the product of a process can be also used as a resource for the next process or a fuel for a vehicle. We are using the term resource for any materials or source of energy. Therefore in GREET.net Coal, Electricity, Sun or Ammonia will all be in the Resources Database.
