when the price of CEA is 300 /ton, the break-even cost would be 18.0/kg, 19.0/kg and 16.4 /kg H2 respectively. 0 5 10 15 20 25 300 Greenhydrogenreplacingcoalforhydrogenproduction Greenhydrogenreplacingnaturalgasforhydrogenproduction Greenhydrogenreplacinghydrogenproductionfromcokeovengas G reenh ydro genrep l a c em entcostwith  C E A, yua n k g -1 275250225200175150125100756050 CEA,yuan/ton Figure Break-even price between green hydrogen and its substitutions under CEA market The decreasing cost of green hydrogen and the increasing price of CEA will lead to the sooner economic feasibility of green hydrogen metallurgy. Hydrometallurgy is an essential technology for low carbon transition of steel production. Comparing hydrometallurgy and conventional blast furnace ironmaking, the cost can be calculated giving the price of hydrogen, coke and CEA. The production of 1 ton of iron requires 340 kg of coke, costing 850, and 1.25 tons of GHG emissions. It takes 89 kg of hydrogen for per ton iron, at a cost of 14/kg for coke oven gas by-product hydrogen, the price of green hydrogen varies by time, and the carbon emission is 0. Besides, compared to coke oven by-product hydrogen, green hydrogen can reduce an additional 8.05 kgCO2e/kg H2. Giving the CEA prices at 60/ton, 100/ton, and 200/ton, respectively. Calculation shows that by 2030 if the price of green hydrogen drops to 13/kg, and if the CEA price reaches 200/ton, green hydrogen metallurgy is cheaper than both coke metallurgy and by-product 清氢学院 清氢学院 清氢学院 清氢学院 清氢学院 清氢学院 清氢学院 清氢学院 清氢学院 Table Hydrogen Carbon Intensity by Pathways and Standards Source Carbon intensity g CO 2 eq /MJ Carbon intensity kg CO 2 eq /kg H 2 Grid-average electrolysis 301 36 Coal gasification 208.33 25 Methanol cracking 174.17 20.9 Eligibility requirement of 5 FCV pilot city clusters in China 125 15 Natural gas reforming 111.83 13.42 Coke oven gas by-product 108.75 13.05 Chlor-alkali by-product 104.08 12.49 Gasoline 102 Diesel 90 Subsidy requirement of 5 FCV pilot city clusters in China 41.67 5 Low carbon and renewable hydrogen from China T/CAB 0078-2020 Standard 40.83 4.9 EU CertifHy 36.67 4.4 Renewable hydrogen from Eu Renewable Energy Directive II 28.3 3.4 Renewable hydrogen from Eu Taxonomy 25 3 UK low-carbon hydrogen standard 20 2.4 Source Life-cycle Analysis of GHG Emissions of Hydrogen, and Recommendations for China, Research group If the petroleum refining and coal chemical can be included in CEA market, the decarbonization benefits of green hydrogen can be converted into noticeable economic value. Petroleum refining and coal chemistry are the largest hydrogen consumers. The cost of green hydrogen is expected to be 30/kg, 13/kg and 8/kg in 2022, 2030 and 2050 respectively. By 2030, when the price of CEA is 50-300/ton, the cost of green hydrogen per unit quality of chemical products, can be reduced by 7.7-46.2, which starts to be slightly lower than that of grey hydrogen. In 2050, when the price of CEA is 50-300/ton, the cost of green hydrogen per unit can be reduced by 12.5-75, which is significantly lower than that of grey hydrogen. Taking ammonia for instance, if ammonia is sold at 4,200/t and the total cost is about 3,500/t, the gross margin is 20. By 2030, if green hydrogen drops to 13/kg, the cost of coal gasification hydrogen keeps 12/kg, and the price of CEA reaches 100/t, the combined cost of using green hydrogen and gray hydrogen for 1 ton ammonia is 2454 and 2680 respectively, saving an additional material cost of 226, and the gross margin can rise from 20 to 25.9. In summary, when the grey hydrogen cost plus green hydrogen decarbonization benefit could equal the green hydrogen cost, it can be considered that green hydrogen could replace grey hydrogen economically. When the price of CEA is 60 /ton, the break-even price between green hydrogen and coal gasification, SMR and coke oven by-product hydrogen is 13.2 /kg, 17.0 /kg and 14.5 /kg H2 respectively; when the price of CEA is 300 /ton, the break-even cost would be 18.0/kg, 19.0/kg and 16.4 /kg H2 respectively. 0 5 10 15 20 25 300 Greenhydrogenreplacingcoalforhydrogenproduction Greenhydrogenreplacingnaturalgasforhydrogenproduction Greenhydrogenreplacinghydrogenproductionfromcokeovengas G reenh ydro genrep l a c em entcostwith  C E A, yua n k g -1 275250225200175150125100756050 CEA,yuan/ton Figure Break-even price between green hydrogen and its substitutions under CEA market The decreasing cost of green hydrogen and the increasing price of CEA will lead to the sooner economic feasibility of green hydrogen metallurgy.

Hydrogen fuel cell heavy-duty vehicle HDV are one of the effective ways to decarbonize road transport. At the current price, without subsidies, 49-ton fuel cell HDV are far more expensive than diesel and electric ones. By 2030, benefited from the decreasing of whole vehicle cost and hydrogen price, the Total Cost of Ownership TCO of fuel cell HDV may be lower than diesel HDV. When the CCER market is restarted, the fuel cell HDV owners can use this market-based mechanism to convert the decarbonization benefits into cash flows. According to the calculation, giving the price of CCER 60 /ton and the price of hydrogen 35 /kg, the TCO of hydrogen fuel cell HDV is 851.7 /100 km, while CCER income is about 6.4/100 km, accounting for less than 1, which is too little to impact the cost.

Compared with CCER, the price decreasing of fuel cell HDV and hydrogen has a greater impact on TCO. However, CCER is still helpful in promoting the scale up of hydrogen fuel cell vehicles. 清氢学院 清氢学院 清氢学院 清氢学院 清氢学院 清氢学院 清氢学院 清氢学院 清氢学院 hydrogen metallurgy.

For carbon market, it is necessary to include chemical and metallurgy into CEA market as early as possible. Meanwhile, the voluntary emission reduction tools as represented by CCER also need to be restarted soon. For standards and regulations, a national standard for green hydrogen needs to be formed as soon as possible. The conversion mechan
