Techno-Economic Analysis (TEA) & Life Cycle Assessment (LCA)

REI provides Techno-Economic Analysis (TEA) and Life Cycle Assessment (LCA) to support technology development, scale-up, and commercialization decisions for energy-intensive and industrial processes. Our work focuses on early-stage and first-of-a-kind technologies, where understanding cost, risk, and environmental impact is critical.

Techno-Economic Analysis (TEA)

REI’s Techno-Economic Analysis translates technical performance into clear economic insight. Our TEA studies are grounded in detailed process and reactor modeling, enabling defensible assumptions and realistic scale-up projections.

Capabilities include:

  • Process- and system-level mass and energy balance development

  • Bottom-up CAPEX and OPEX estimation for early-commercial systems

  • Sensitivity and scenario analysis to identify key cost drivers and performance thresholds

  • Scale-up assessments linking laboratory, pilot, and commercial performance

TEA results are used to compare technology pathways, define meaningful performance targets, and inform R&D and investment decisions.

Payback vs. Efficiency Gains

 

Life Cycle Assessment (LCA)

REI conducts Life Cycle Assessments to quantify environmental impacts, with a primary focus on “cradle-to-gate” system boundaries appropriate for early-stage technology development.

Capabilities include:

  • Cradle-to-gate LCA modeling from raw materials through process output

  • ISO 14040/14044-aligned methodology

  • Greenhouse gas emissions accounting for emerging and decarbonization pathways

  • Identification of dominant emissions drivers and environmental hot spots

  • Comparative evaluation of alternative process configurations

LCA results are used to identify high-leverage decarbonization opportunities and guide technology design decisions.

Cradle-to-gate Emissions

 

Integrated TEA + LCA

REI integrates TEA and LCA to evaluate both economic and environmental performance within a consistent framework.

This integrated approach enables:

  • Identification of tradeoffs between cost, efficiency, and emissions

  • Comparison of technology pathways under consistent assumptions

  • Development of metrics such as carbon abatement cost ($/tonne CO₂ avoided)

By linking process-level modeling, economics, and cradle-to-gate environmental analysis, REI helps clients move from technical concept to informed deployment strategy.
