The requirement of steel may be fulfilled either through indigenous production and/or through, one ton of steel currently costs in the order of €400, which includes about €50 required for the coal used. Replacing this coal with hydrogen would require around €180 worth of hydrogen at current best prices (€3.6/kg), which would increase the total price of a ton of steel by about one third.The potential of hydrogen for decarbonising steel production

Coal & Steel Production FutureCoal

Coking coal is converted to coke by driving off impurities to leave almost pure carbon. The coking coal is crushed and washed. It is then ‘purified or ‘carbonised in a series of coke ovens, known as batteries, where the coking coal is heated to 1000-1100ºC in the absence of oxygen for 12-36 hours.Total Domestic Production for 2020-21 stood at 716.09 Million Ton . 2020-21 was 906.13 Million Tones (MT). Out of which total coal import was 215.25 MT which was 23.75% of the total requirement. The This will help in reducing the import of coking coal as it can be blended with high grade imported prime coking coal for steelTotal Domestic Production for 2020-21 stood at 716.09 Million Ton

Steel and emissions: How can we break the link? Bellona

The global iron and steel industry accounts for approximately 5% of total global CO2 emissions. On average, 1.9 tonnes of CO2 are emitted for every tonne of steel produced. About 2.8MtCO2 per year are solely related to energy use in the iron and steel sector, about 8% of total energy-related emissions[i]. Over 1.3 billion tons of steel are Manufacturing 1 ton of steel needs 50 kg of hydrogen. Replacing coal with hydrogen would raise the total price of a ton of steel by almost one-third. If large-scale hydrogen generation reduces the price of H 2 to €1.80/kg by 2030, the price difference between green hydrogen steel and conventional steel would be 10%.
