Curated Data Sources
A curated list of public datasets and databases useful for early-stage climate TEAs — covering energy, chemicals, materials, and industrials.
Finding trustworthy data is consistently the hardest part of building a TEA. This list covers the public sources we return to most often across energy, chemicals, materials, and industrials.
These are starting points, not substitutes for validation. For each assumption that materially affects your model, triangulate across at least two or three sources and document where your numbers come from.
Energy & Power
NREL Annual Technology Baseline Comprehensive cost and performance data for electricity generation technologies. The standard reference for energy-sector TEAs — updated annually, with historical data for trend analysis.
DOE Hydrogen and Fuel Cell Technologies Office Technical targets, cost projections, and production pathway data for hydrogen technologies. Covers electrolysis, SMR, biomass pathways, and more.
IEA Energy Technology Perspectives Global energy technology cost and deployment data across sectors and scenarios. Useful for benchmarking and understanding where costs are heading.
Chemicals & Industrials
Chemical Engineering Plant Cost Index (CEPCI) The industry standard for adjusting process plant construction costs over time. Essential for converting historical capex data to current-year dollars.
ICIS Chemical Pricing Feedstock and commodity chemical pricing. Some data is paywalled, but spot prices and historical trends are partially accessible.
Materials & Mining
USGS Mineral Commodity Summaries Annual data on production, imports, exports, and prices for over 90 mineral commodities. The most reliable public source for critical mineral pricing.
LME (London Metal Exchange) Real-time and historical pricing for base metals. Free historical data available with registration.
Carbon & Emissions
EPA Emission Factors for Greenhouse Gas Inventories Standard emission factors for calculating carbon intensity across processes, fuels, and materials. Required reading for any TEA with a carbon intensity component.
GREET Model (Argonne National Laboratory) Life cycle analysis tool with embedded emissions and energy data for transportation fuels, electricity, and materials. Free to download.
