Summary
The global transition to a carbon-neutral economy demands a paradigm shift in bioenergy technologies. To meet future energy needs, we must advance beyond conventional methods toward high-efficiency, engineered systems that maximize resource recovery across all conversion pathways.
This Special Issue, "Next-Generation Bioenergy Systems for a Carbon-Neutral Future: Process Intensification, Hybrid Integration, and Scale-Up," aims to bridge the gap between fundamental science and applied energy engineering. We focus on technological developments in thermochemical and biochemical conversion, alongside system-level optimization. We invite papers that demonstrate how advanced engineering solutions can improve reaction kinetics, reduce capital costs, and accelerate industrial scale-up.
We welcome original research and reviews covering the following themes:
· Thermochemical Conversion Engineering: Technological developments in gasification, fast/slow pyrolysis, torrefaction, hydrothermal processes, and clean combustion strategies.
· Process Intensification (PI): Novel reactor designs (e.g., oscillatory baffled, micro-channel), reactive separations, and catalytic engineering for improved heat/mass transfer.
· Hybrid Integration: Coupling bioenergy with solar, wind, or hydrogen (Power-to-X); and poly-generation systems (CCHP) for maximized efficiency.
· Scale-Up & Analysis: Engineering challenges in pilot-to-plant upscaling, digital twin simulations, and robust Techno-Economic (TEA) and Lifecycle Assessments (LCA).
We look forward to receiving your contributions to this pivotal topic.
