STRE3AM

Strategic Technology Roadmapping, and Energy, Environmental, and Economic Analysis Model

The Strategic Technology Roadmapping and Energy, Environmental, and Economic
Analysis Model STRE3AM is an optimization-based modeling tool and
analysis framework to assist with strategic planning and technology investments
of the industrial sector. This open-source framework is written in Julia using
JuMP objects, which enables users to model future pathways for incumbent and
future production technologies, fuels and energy carriers, emissions, and other
impacts from industries as they transform in pursuit of a robust, competitive,
resilient, and sustainable manufacturing sector. The model starts with an
initial stock of industrial production technologies and assets at a facility
level or an aggregated national level, and then determines pathways that
minimize cost or similar economic objective(s), subject to an array of
constraints on demand, annual or cumulative emissions, market shares, and other
exogenously specified operational considerations such as capacity utilization
rates or regional availability of feedstocks and energy sources. Key features of
the framework include flexibility to model a wide range of industries and
industrial technologies/processes at varying levels of granularity from
facility-level to regional or national level, ability to perform parametric
sensitivity analyses, and ability to visualize model results using visualization
objects.

Key Requirements

• Julia
• Conda
• Git

Quick installation

After installing Julia, conda, and git.

In the terminal the following should be typed.

git clone https://github.com/ANL-CEEESA/STREAM.git

This will clone the repository. Then at the STREAM repository, start the
Julia REPL by typing in the terminal:

julia

Then, at the REPL pressing the ] key one, would start the package manager,
i.e.,

(@v1.11) pkg> 

At this point the following command should activate the environment,

activate .

Followed by

instantiate

This will get the stre3am module ready to be used. E.g. at the command-line
interface,

user@local directory % julia --project=/path_to_STREAM/

julia> using stre3am

The final step is optional.
At the STREAM folder, the following must by typed in the terminal:

conda env create --name stre3am --file environment.yml 

And then activating i.e. conda activate stre3am.
