Research areas

Feasibility & TEA

Published techno-economic assessments explore unit economics, CAPEX/OPEX, incumbent benchmarks, sensitivity and verdict-flip thresholds.

FOAK / TRL 7→9 research

Scale-up risk, the gap between a flawless lab coupon and a financeable plant, where the physics quietly breaks the spreadsheet — read by someone who has carried first-of-a-kind projects across the finish line.

Independent second opinion

Background

The published work draws on six years of first-of-a-kind commercial development at a waste-to-fuels pioneer and a 13-country book of projects. David Zheng, P.Eng., MBA brings engineering, commercial experience and process economics to research in English and Mandarin.
