Abstract
Power-to-Hydrogen is crucial for the renewable energy transition, yet
existing literature lacks business models for the significant excess heat it
generates. This study addresses this by evaluating three models for selling
electrolyzer-generated heat to district heating grids: constant, flexible, and
renewable-source hydrogen production, with and without heat sales. Using
agent-based modeling and multi-criteria decision-making methods (VIKOR, TOPSIS,
PROMETHEE), it finds that selling excess heat can cut hydrogen production costs
by 5.6%. The optimal model operates flexibly with electricity spot prices,
includes heat sales, and maintains a hydrogen price of 3.3 EUR/kg.
Environmentally, hydrogen production from grid electricity could emit up to
13,783.8 tons of CO2 over four years from 2023. The best economic and
environmental model uses renewable sources and sells heat at 3.5 EUR/kg
