Whr-charging-hub: techno-economic model of waste heat recovery at megawatt charging hubs

Description

MATLAB model for the techno-economic assessment of waste heat recovery at megawatt charging hubs for battery-electric heavy trucks. The liquid-cooled charging points reject heat that can be sold to a heat network. The model compares two ways of connecting a hub: • TSN – feed-in to a low-temperature source network (5GDHC) through a plate heat exchanger • DH – feed-in to a conventional district heating network through a heat pump For both paths it calculates the levelised cost of heat (LCOH), the net present value (NPV) and the discounted payback period. It also shows how these respond to connection distance, hub size, energy prices, subsidy rate and every cost assumption. The package contains: • an interactive explorer app (WhrExplorerApp) with a guided Live Script tour • the full calculation chain as plain MATLAB functions • run_all.m, which reproduces all tables and figures of the accompanying study • a test suite (107 tests) and a complete model reference (docs/model_reference.md) Requirements: base MATLAB, no toolboxes (tested with R2026a; the Live Script tour needs R2025a or newer). Quick start: run setup_path, then WhrExplorerApp. See README.md for details. Accompanies: Müller et al.
