Ever wanted to run an energy system model with your own assumptions?

We've made a simplified version of our 45-node European sector-coupled model available to run online.

It includes renewables, CCS, nuclear, power, hydrogen, biomass, industry, etc.

model.energy/scenarios/

You can ask it questions like:

i) At what cost does nuclear take over (around 3-4000 EUR/kW)

ii) What happens if we restrict power or hydrogen grid (costs go up!)

iii) What happens if we relax restriction on carbon sequestration from 200 MtCO2/a (costs go down!)

See scenarios others have run here:

model.energy/scenarios/resu…

Submit your own scenarios here (takes several minutes):

model.energy/scenarios/subm…

To run in reasonable time with open source, there are some strong simplifications:

a) Model is greenfield, e.g. ignores existing generators.

b) Time resolution is sampled for full year at most 25-hourly.

c) Only 45 nodes for Europe (proper model requires 200 for good results).

More info on the original, full model PyPSA-Eur-Sec here (that doesn't include above simplifications):

Any feedback/comments very welcome, but cannot fix things quickly ;-).

PS The online interface is still rough around the edges and the model needs more explanation everywhere (it was an after-hours hobby project).

But the code is open and anyone can contribute to further development:

PPS There is more detail and context on the underlying model in this slide deck:
