INDUSTRIAL TRANSFORMATION TECHNOLOGY AND INVESTMENT MODEL DOCUMENTATION

The Industrial Transformation Technology and Investment Model (ITTIM) is an Excel-based tool that estimates energy use, CO2 emissions, and capital investment needs for industrial decarbonization. It employs a six-tier cumulative technology framework—ranging from energy efficiency to clean chemical feedstocks—to mitigate 97% to 99% of industrial emissions. The model currently supports datasets for China, India, Indonesia, Viet Nam, the Philippines, and the United States, allowing users to simulate various scenarios including carbon pricing and different hydrogen cost projections.

• The ITTIM utilizes a cumulative six-tier technology framework to address industrial emissions, which together can mitigate between 97% and 99% of energy-related and cement calcination emissions in each modeled region.
• The technology tiers are prioritized by cost, maturity, and practicality: Tier 1 focuses on material and energy efficiency; Tier 2a and 2b cover electrification of low- to high-temperature processes; Tier 3 implements Carbon Capture and Use or Storage (CCUS); Tier 4a replaces remaining fossil fuels with green hydrogen; and Tier 4b transitions to clean chemical feedstocks.
• The model's geographic scope includes datasets for China, India, Indonesia, Viet Nam, the Philippines, and the United States (including 48 contiguous states), which collectively represented 64% of global industrial energy-related CO2 emissions in 2019.
• The ITTIM estimates both energy costs and capital equipment costs, though it excludes costs for land, buildings, installation, and operations and maintenance.
• The model allows users to simulate carbon pricing from $0 to $250 per tonne of CO2, which affects the cost-effectiveness of interventions but does not change the choice of technologies because the tool is not a cost-driven optimization model.
• Green hydrogen costs in the 'High Improvement' scenario for 2050 vary by region, ranging from $1.80/kg in China and India to $3.53/kg in the Philippines.
