INDUSTRIAL TRANSFORMATION TECHNOLOGY AND INVESTMENT MODEL DOCUMENTATION

The Industrial Transformation Technology and Investment Model (ITTIM) is a free, open-source Excel-based tool designed to map transition pathways for achieving non-emitting industrial sectors. It estimates energy use, CO2 emissions, expenditures, and capital investment needs across various regions and subindustries, utilizing a cumulative six-tier technology framework to mitigate 97% to 99% of industrial energy-related and cement calcination emissions.

• The ITTIM utilizes a cumulative six-tier technology framework to decarbonize industry, which together mitigate between 97% and 99% of industrial energy-related and cement calcination emissions in each region.
• The technology tiers are prioritized by cost, maturity, and practicality: Tier 1 focuses on material, product, and energy efficiency; Tier 2a covers non-thermal and low-temperature electrification (below 150 °C) and secondary steelmaking; Tier 2b addresses medium- and high-temperature electrification; Tier 3 implements Carbon Capture and Use or Storage (CCUS) for specific high-temperature processes; Tier 4a replaces remaining fossil fuels with green hydrogen combustion; and Tier 4b transitions to clean chemical feedstocks.
• The model includes datasets for six countries—China, India, Indonesia, Viet Nam, the Philippines, and the United States—as well as the 48 contiguous U.S. states. These six countries represented 64% of global energy-related CO2 emissions from the industrial sector in 2019.
• The ITTIM estimates two primary cost types: energy costs and capital equipment costs. It explicitly excludes costs for land, buildings, installation, and operations and maintenance, as the latter are assumed to be similar between clean and emitting technology variants.
• The model provides three pricing scenarios for green hydrogen based on 2050 projections. Under the default 'High Improvement' scenario, costs are $1.80/kg in China and India, $3.50/kg in Indonesia, $2.17/kg in Viet Nam, $3.53/kg in the Philippines, and $3.00/kg in the United States.
• The model tracks various pollutants beyond CO2, including fugitive methane (in CO2e), and direct industrial emissions of fine particulate matter (PM2.5), sulfur dioxide (SO2), and nitrogen oxides (NOX). It also estimates public health outcomes such as premature mortality, nonfatal heart attacks, new asthma cases, lung cancer cases, and strokes.
