Patent granted on system for feeding biomass to high-pressure reactors

A newly granted patent covers a system designed to reliably feed low-density biomass and waste into high-pressure reactors, tackling bridging, compaction, and flow instability—the “pressure gap” that has historically forced pre-grinding or pelletizing and limited scale-up. By addressing this gap, the technology aims to reduce preprocessing needs and enable more stable, continuous operation for biomass- and waste-to-energy processes.

What specific mechanisms in the patented design overcome the pressure gap (e.g., sealing, pressure staging, compaction control), and how do its costs and efficiencies compare with conventional lock-hopper or plug-screw feeders?
