Novel adaptation for existing blast furnaces could reduce steelmaking emissions by 88%; closed-loop carbon recycling

Green Car Congress

Researchers from the University of Birmingham have designed a novel adaptation for existing blast furnaces that could reduce CO 2 emissions from the steelmaking industry by nearly 90%. Iron and steelmaking is the biggest emitter of CO 2 of all foundation industrial sectors, accounting for 9% of global emissions. 2023.135963.

Global Carbon Budget 2022: Global fossil CO2 emissions expected to grow 1.0% in 2022

Green Car Congress

Growth in oil use, particularly aviation, and coal use are behind most of the increase in 2022. During the Global Financial Crisis in 2008/9, the COVID19 pandemic, and now the Ukrainian War, economic stimulus packages were meant to put the world on a cleaner and greener path, but this is not at all evident in the CO 2 emissions data.

How to Hasten India’s Transition Away From Coal

Cars That Think

Greenhouse gas emissions will certainly grow too, because India’s energy generation is dominated by fossil fuels—coal-fired power plants for electricity, coal- and gas-fired furnaces for industrial heating, liquid petroleum gas for cooking, and gasoline and diesel for transportation. cents per kilowatt-hour and 5.5 IIT Madras.

ICCT LCA study finds only battery and hydrogen fuel-cell EVs have potential to be very low-GHG passenger vehicle pathways

Green Car Congress

This study uses recent data on industrial-scale battery production and considers regional battery supply chains. Natural gas does not offer climate benefits compared to gasoline and diesel, and many biofuel pathways do not, either. This is especially important for assessing the GHG emissions of PHEVs.
