New Deliverable Online Now: Definition of the Base and Reference Cases for the KPIs Assessment

Among all the industrial sectors, the steel and the fertiliser industries are two of the most energy and carbon-intensive ones. The annual emission of the steel industry is equivalent to 9% of the total global CO2 emissions and 16% of total industrial CO2 emissions. Similarly, the fertiliser sector is responsible for a significant share of CO2 emissions, making the emissions directly related to these two manufacturing processes equivalent to 30% of the emissions of all industrial sectors.

In a steel plant, around 50% of the total CO2 emissions come from the power section where residual Basic-Oxygen-Furnace-Gas (BOFG) and Blast-Furnace-Gas (BFG) are used as fuel to cover the electricity demand of the plant. The remaining CO2 emissions are attributed to several sections in the steel plant.

CO2 direct emissions from the urea sector are mainly related to the synthesis of ammonia that is combined with carbon dioxide to produce urea. In fact, in the ammonia plants, fossil fuels are burnt to supply the necessary heat in the primary reformer.

The INTIATE project aims to show how in an operational environment residual carbon-rich gas from the steel sector can be used as a valuable feedstock for ammonia and urea production. In the demonstration of the bankability of this concept, a sound techno-economic evaluation is key.

In the Deliverable 5.3 ‘’Definition of the base and reference cases for the KPIs assessmentpublished earlier today, the base and reference cases along with the main key performance indicators are defined with the aim of the later assessment of the INITIATE concept. “Base cases” means state-of-the-art commercially available plants, while “reference cases” refers to state-of-the-art commercially available plants with CO2 capture technologies. Deep analysis, in terms of heat and mass balances, overall energy performance, as well as costs, of steel, ammonia and urea plants were performed and described in this document.

A presentation of Deliverable 5.3 is available on our website in the learning resources section.
