Introduction. The United States (US) chemical industry consumes roughly 7,000 trillion BTUs of energy annually, accounting for over 10% of the total energy consumption in 2018 . As such, the chemical industry contributes a significant fraction of the US greenhouse gas (GHG) emissions, ranking 7 th amongst anthropogenic contributors . The deepening climate emergency underscores the urgent need to reduce the carbon footprint of manufacturing; key contributors to this footprint are the combustion of fossil fuels and the production of basic feedstocks. A potential decarbonization strategy consists of capturing and converting emitted CO2 into chemicals (e.g., producing methanol through CO2 hydrogenation); alternatively, it is also possible to reduce the generation of CO2 during the production of key feedstocks (such as hydrogen) . Hydrogen production, in particular, accounts for 3% of the global CO2 emissions ; this is because nearly 50% of all the hydrogen in the world is produced via steam-methane reforming (SMR), which is an energy-intensive process . It is estimated that the global warming potential (GWP) of producing 1 kg of hydrogen via SMR is 11.8 CO2-eq kg .
