model.energy/products: online optimisation of hydrogen-based e-product delivery

This is the code for the online optimisation of hydrogen-based e-product delivery from wind and solar.

It uses only free software and open data, including Python for Power System Analysis (PyPSA) for the optimisation framework, the European Centre for Medium-Range Weather Forecasts (ECMWF) ERA5 dataset for the open weather data, the atlite library for converting weather data to generation profiles, Clp for the solver, D3.js for graphics, Mapbox, Leaflet and Natural Earth for maps, and free software for the server infrastructure (GNU/Linux, nginx, Flask, gunicorn, Redis).

You can find a live version at:

https://model.energy/products/

The tool is a simplified version of the model behind the research paper Import options for chemical energy carriers from renewable sources to Germany by Johannes Hampp, Michael Düren and Tom Brown in PLOS ONE, 2023.

Requirements

Software

This software has only been tested on the Ubuntu distribution of GNU/Linux.

Ubuntu packages:

sudo apt install coinor-clp coinor-cbc redis-server

To install, we recommend using miniconda in combination with mamba.

conda install -c conda-forge mamba
mamba env create -f environment.yaml

For (optional) server deployment:

sudo apt install nginx
mamba install gunicorn

Data

This uses the same data as https://model.energy/, see the WHOBS-server repository.

Regenerate default assumptions

The basic assumptions in defaults-initial.csv are added to by the script generate_defaults.py, which adds assumptions from the trace repository and technology-data repository (which is in turn largely based on the Danish Energy Agency's Technology Data). The CSV defaults.csv is an output of this script and should not be modified. All modifications should be make in defaults-initial.csv.

To run the script do:

python generate_defaults.py

Run server locally on your own computer

To run locally you need to start the Python Flask server in one terminal, and redis in another:

Start the Flask server in one terminal with:

python server.py

This will serve to local address:

http://127.0.0.1:5002/

In the second terminal start Redis:

rq worker efuels

where efuels is the name of the queue. No jobs will be solved until this is run. You can run multiple workers to process jobs in parallel.

Deploy on a publicly-accessible server

Use nginx, gunicorn for the Python server, rq, and manage with supervisor.
