Assumptions
The current case fixes a 2050 horizon, hourly balances, candidate network expansion and technology availability. Assumptions are working inputs, not policy commitments.

Report 01 · The Joule Model
Europe, as one connected system.
A working 2050 model scenario for examining how electricity, hydrogen, methane and synthetic fuels interact across the continent.
Current model
How the four carrier networks are modelled together.
The model co-optimises electricity, hydrogen, methane and synthetic-fuel networks with storage, cross-border flows and demand-side flexibility. Results can be viewed at continental, country, node, sector and technology level, with the assumptions available alongside them.

Methodology
Assumptions, outputs and sources.
Outputs
Charts and tables report solved scenario values by geography, carrier, sector and technology. Values remain subject to model and editorial review.
Sources
Source registers are maintained in the study shell, with public reference points including ENTSO-E Transparency, Eurostat and ENTSOG.

Model architecture
The four connected networks.
Electricity
Generation, storage, demand response and candidate transmission expansion are co-optimised at hourly resolution.
Hydrogen
A 110-node network connects electrolysis, reforming, pyrolysis, ammonia gateways and storage.
Methane
Biomethane, LNG backup and pipeline repurposing expose the spatial trade-offs between gas and hydrogen.
Synthetic fuels
E-kerosene and e-methanol are represented at system nodes alongside five import gateways.
