Request for Information (RFI) on Steel Made via Emissions-Less Technologies (SMELT)

Description

Request for Information (RFI): Steel Made via Emissions-Less Technologies (SMELT) This is a Request for Information (RFI) only. This RFI is not soliciting application for financial assistance. The purpose of this RFI is solely to solicit input for ARPA-E consideration to inform the possible formulation of future programs. The purpose of this RFI is to solicit input for a potential future ARPA-E-funded research program focused on novel technical approaches to produce iron metal (Fe) from iron-containing ores, which can create new technology pathways to enable future net-zero GHG emissions steelmaking at global scale. Global steel production – 1,700 million tonnes (Mt) of crude steel annually, of which 2/3 is primary production from ores and 1/3 is secondary scrap recycling2 – accounts for ~7% of world energy use (over 38 EJ) and ~7% of global GHG emissions4 (3.5 Gt CO2e). The most widespread primary steelmaking pathways are: (1) blast furnace ironmaking-basic oxygen furnace steelmaking (BF-BOF) which emits ~2.2 t CO2/t steel, and (2) natural gas direct reduced ironmaking-electric arc furnace (NG DRI-EAF) steelmaking, which emits ~1.4 t CO2/t steel. Annual domestic steel production (~80 Mt steel) accounts for ~4% of U.S. emissions and 2% of U.S. energy use; the remainder of annual U.S. steel demand (~43 Mt steel) is imported. Global steel production is expected to almost double, reaching ~2,500 Mt steel per year by 2050 as GDP per capita increases in developing nations. Despite steel’s role in achieving sustainable development goals, these increasing emissions must be abated to avoid the most disastrous effects of climate change. The most emissions-intensive stage in the value chain from ore to steel products is ironmaking (see ARPA-E Iron & Steel Webinar7 overview). There are no zero-emissions ironmaking technologies yet available at scale to replace these routes. Accordingly, this request for information (RFI) focuses on novel zero-emissions ironmaking processes with a credible future path toward enabling zero-emissions steelmaking at global scale (~2 Gt steel/yr). A dominant medium-term strategy toward this goal is to retrofit carbon capture systems (CCS) onto blast furnaces, which will increase the levelized cost of crude steel; the estimated premium is ~$130/t steel, as shown in Figure 1. A dominant long-term strategy for many global steel companies is water electrolysis to produce hydrogen followed by hydrogen direct reduced ironmaking (H2 DRI).H2 DRI is currently more expensive than CCS retrofit given today’s electrolyzers and electricity prices, but may approach a cost-competitive range if electrolyzer R&D is successful and electricity prices drop.

THIS NOTICE DOES NOT CONSTITUTE A FUNDING OPPORTUNITY ANNOUNCEMENT (FOA). NO FOA EXISTS AT THIS TIME.
