    Climate Tech Unit Economics & TEA Modeler

    Demonstrate your pathway to cost parity. Calculate your Levelized Cost ($/tCO2, $/kg H2, $/kWh) with CapEx amortization, clean power sensitivities, and FOAK-to-NOAK learning curves.

    Step 1: Facility Capacity & Total CapEx

    Plant Sizing, Overnight Capital & Financing

    Define nameplate annual output, total installed facility CapEx, operating lifetime, and financing hurdle rate (WACC).

    Venture-Grade Climate Modeling

    Need an investor-ready 3-statement financial model & TEA for Series A?

    SlickBooks builds venture-grade techno-economic analyses, CapEx depreciation schedules, and DOE loan guarantee models for deeptech climate startups.

    Why Venture Investors Demand a Techno-Economic Analysis (TEA)

    Unlike software companies where gross margins are 80% on day one, deeptech and climate hardware startups scale through physical infrastructure:

    1. Levelized Cost Parity

    Investors need to see when your cost per unit ($/ton of CO2 or $/kg H2) undercuts incumbent fossil or chemical alternatives (the Green Premium crossover point).

    2. Surviving the FOAK Valley

    First-Of-A-Kind (FOAK) commercial plants have high overnight CapEx. A robust TEA shows how unamortized engineering costs compress as capacity doubles.

    3. Power Sensitivity Modeling

    For electrochemical and DAC systems, electricity is up to 60% of OpEx. Modeling sensitivity to $/MWh clean PPAs is critical for site selection and project finance.

    Methodology & Published Benchmark Sources

    The default parameters and scaling curves in this tool are calibrated against published institutional techno-economic literature:

    Carbon Removal & Clean Hydrogen
    • Direct Air Capture: NREL / National Academies TEA methodology on solid/liquid sorbent systems ($100/tCO2 target).
    • Green Hydrogen: IEA & US DOE Hydrogen Shot technical benchmark guidelines ($2.00/kg target by 2030).
    Scaling Curves & Capital Amortization
    • Capital Recovery Factor (CRF): Standard discounted cash flow annuity formulation based on WACC and facility design life.
    • Wright’s Law Learning Rates: Historical empirical clean energy learning rates (12%–18% per cumulative doubling).

    Frequently Asked Questions

    Everything you need to know about climate techno-economic modeling.

    Why does CapEx dominate early-stage climate unit economics?

    For First-Of-A-Kind (FOAK) facilities, unamortized non-recurring engineering (NRE) costs and pilot fabrication expenses are spread over relatively small initial output volumes. As manufacturing scales to gigawatt or megaton volume, annualized CapEx per unit typically falls by 60% to 80%.

    What is the difference between WACC and discount rate in a TEA?

    The Weighted Average Cost of Capital (WACC) represents the blended cost of debt and venture equity used to finance the project. A higher WACC (e.g. 12% for unproven FOAK vs 6% for mature utility project debt) increases the Capital Recovery Factor and consequently raises the Levelized Cost.
