The industrial sector is characterized by 6 demand segments, each representing either the physical output of the industry or the total energy requirement (Table 3.5.1). There are also one demand for 'Other non-specified energy consumption (ONO)', one for 'Industrial and Other non-energy uses (NEO)' and one for 'Other Industrial consumption (I0I)', which are considered as a generic demands. The last one (I0I) has been added for minor calibration purposes and is generally not used. There are different technologies and fuels modelled for supplying steam, process heat, machine drives and electro-chemical process for each energy-service demand in the Base-year templates.

|I0I||Other Industrial consumption||PJ|
|IIS||Iron and Steel||Mt|
|ILP||Pulp and Paper||Mt|
|NEO||Industrial and Other Non Energy Uses||PJ|
|ONO||Other non-specified consumption||PJ|
Energy service demands are projected to 2100 using general economic and demographic drivers population, GDP, GDP per capita and sectoral output). To develop projections of future energy service demands, estimates of drivers are used in conjunction with user assumptions on the topic of service demand sensitivity to these drivers. Projected industry sector energy-service demands at a global level are presented in Figure 3.5.1. Similar tables have been generated for each region. Industry sector has relatively high growth in China as compared to other regions.

There are hundreds of technologies modelled in the industry sector to meet the energy-service demands. For each energy-services of each industry, a number of existing technologies are in competition to satisfy energy-service demand. They are characterized by an efficiency, an annual utilization factor, a lifetime, operation costs, and six seasonal share coefficients (summer-day, summer-night, intermediary day, intermediary-night, winter-day, winter-night). The technologies included in the Base-Year template are the existing technologies to meet the base-year demand and the residual capacities can be used till end of their life period. No new investments are allowed in the existing technologies in any sector. . These technologies progressively replace the existing ones and they are characterized by the same type of parameters such as efficiency, and investment cost. Regional specific hurdle rates are applies to industry sector new technologies as shown in Figure 3.5.2. It varies from 10% (developed countries) to 20% (least developed countries).
