Advancesteel8/24/2023 Of the programme will be determined at a later date. In light of the current restrictions on access to HBI technologies, the timeline Going forward, when sufficient volumes of "green" hydrogen and industrialized technologies of hydrogen-based reduction become available, the decarbonization potential of the process should exceed 90% (vs. Even with the current energy consumption structure, the above route allows for a twofold reduction of CO2 emissions compared to the BF-BOF route. In 2021, NLMK Group adopted its Climate Programme that envisages a phased transition to the electric arc method of steel production based on DRI/HBI as feedstock (coke-free iron ore with a high iron content). More significant reductions can be achieved through transition from coal to "green" hydrogen and switch to the HBI+EAF process (hot-briquetted iron + electric arc furnace). The CO2 reduction potential for BF-BOF steelmaking, given the existing technology and possible advancements, is limited to 5-15% of the current levels (excluding carbon capture, utilization, and storage 3). NLMK Group's management devotes particular attention to climate aspects when considering the Company's strategy, risk management, annual budget, and business plans, as well as when setting the Company's business goals and monitoring the implementation and efficiency of major investments.įor more information on climate-related issues, please visit the Company website. The Company evaluates progress towards achieving the goals annually. Goals related to climate impact reduction are assigned by the CEO (Chairman of the Management Board) to the functional divisional managers of the Group, as well as the heads of production divisions at NLMK Group companies. The Board of Directors Strategic Planning Committee determines climate impact reduction goals. The agenda of the BoD meetings includes such issues as the decarbonization strategy, climate projects, climate risks, methodologyĪnd benchmarking, progress towards achieving the goals. The Company's leadership devotes continued attention to climate-related issues, which are embedded into its corporate governance system. Our approach to managing climate change-related issues On Climate-related Financial Disclosures (TCFD) 2 from 2021. In 2023, NLMK Group published its third report in line with the revised recommendations of the Task Force Specific CO2 emissions from scrap steelmaking are approximately four times lower than when using primary raw materials. On average steel produced by NLMK Group consists of 30-35% of recycled resources such as ferrous scrap and other materials that are climate neutral and can significantly reduce the Company's carbon footprint. Emissions avoided with NLMK's products are comparable to emission volumes from the entire steelmaking operations of the Group. Moreover, the Company's products (suchĪs steel for wind energy and energy-efficient electrical steels) enable a broad range of consumer industries to reduce their climate impact substantially. Its performance is nearly close to that of a noble metal-based Pt/C/NF||RuO 2/NF water splitting system.NLMK Group is fully committed to climate change action and takes meaningful steps towards decreasing greenhouse gas emissions, progressively reducing the carbon footprint of its products. The water splitting system composed of NiSe 2-rGO-ST/NF||FeSe 2-rGO-ST/NF electrodes requires only ∼1.75 V at 10 mA cm −2. Furthermore, all catalysts indicate negligible deterioration, indicating better stability during the process of HER and OER after a stability test of 60 h. The FeSe 2/rGO-ST/NF shows a low overpotential (297 mV) at 50 mA cm −2 for the OER compared to RuO 2/NF (325 mV), while the overpotentials of CoSeO 3-rGO-ST/NF and NiSe 2-rGO-ST/NF are 400 and 475 mV, respectively. NiSe 2/rGO-ST shows a remarkable overpotential (52.5 mV) at 10 mA cm −2 for the HER compared to the benchmark Pt/C E-TEK (29 mV), while the overpotential values of CoSeO 3/rGO-ST and FeSe 2/rGO-ST are 246 and 347 mV, respectively. The resulting electrocatalyst composite can enhance mass/charge transfer and promote interaction between water molecules and electrocatalyst reactive sites. Herein, metal selenium nanoparticles (M = Ni, Co & Fe) are anchored on the surface of reduced graphene oxide and a silica template (rGO-ST) through a simple one-pot solvothermal method. Exploration of economical, highly efficient, and environment friendly non-noble-metal-based electrocatalysts is necessary for hydrogen and oxygen evolution reactions (HER and OER) but challenging for cost-effective water splitting.
