Introduction
The transition to low-carbon energy systems requires integrated approaches that combine multiple fuel pathways, feedstocks, and technologies. In emerging economies, this challenge is further complicated by infrastructure constraints, resource distribution, and demand variability.
Integrated Systems Approach
Rather than treating biofuel and e-fuel production as separate systems, an integrated modelling approach enables the optimisation of:
- biomass resource utilisation
- hydrogen production from electrolysis
- carbon capture from industrial sources
- multi-fuel production pathways
This approach allows simultaneous evaluation of multiple energy vectors, including hydrogen, ammonia, methanol, methane, ethanol, diesel, and sustainable aviation fuel.
Role of Spatial Optimisation
Spatial variation in feedstock availability and infrastructure significantly affects system performance. Large-scale optimisation across regions enables:
- identification of optimal plant locations
- minimisation of transport costs
- efficient allocation of resources
Implications for Energy Planning
Integrated modelling provides decision-makers with:
- cost-optimal production pathways
- infrastructure investment insights
- scalable system design strategies
Conclusion
As energy systems become increasingly complex, integrated optimisation frameworks will play a critical role in enabling cost-effective and scalable low-carbon fuel production.
