Table 7. Roadmap to tackle challenges associated with the LOHC.

Theme Advancement Limitations Roadmap Applications Ref.
Thermal neutrality/heat supply Microwave/exhaust-heat concepts; electrified/local heating; induction approaches Endothermic dehydrogenation energy penalty; heat transfer limits Demonstrate net-efficient heat integration and electrified heating with full energy accounting Industrial hubs with waste heat; electrified stations 93
Reactor/process intensification Continuous/intensified reactors; improved transfer control Gas evolution and liquid wetting reduce effective contact; scale-up complexity Scale continuous reactors with validated control & durability High-throughput release units; modular deployments 126
Catalyst innovation Tailored catalyst architectures: Durability focus Deactivation over cycling; sensitivity to real feeds/carrier impurities Shift metrics from activity to lifetime and regenerability Any LOHC deployment 27
Carrier molecule strategy Broader material portfolios; “lower enthalpy carriers” concept No universal best carrier; trade-offs between heat demand and chemical sensitivity Match carriers to heat-grade availability and purity needs; standardise specs DBT-like for logistics; NEC-like, where a lower temperature is crucial 105
System TEA/LCA More lifecycle/chain-level reviews TEA/LCA often lacks durability/operations realism Bankable demos: validated cycles, supply chain specs and safety standards Early industrial corridors; demonstration refuelling corridors 11
