Steam methane reforming (SMR) is a widely used industrial process for producing hydrogen by reacting methane with steam at high temperatures in the presence of a catalyst. It is the most common method for hydrogen production, but it also generates significant carbon dioxide emissions, which has implications for its environmental impact and the pursuit of cleaner energy solutions.

Steam Methane Reforming

Hydrogen production involves various methods to generate hydrogen gas, a clean energy carrier, from different sources like water, natural gas, and biomass. The choice of production method impacts the environmental footprint, cost, and scalability of hydrogen as a sustainable energy solution.

Hydrogen Production

Methane (CH4) is a potent greenhouse gas with a global warming potential significantly higher than carbon dioxide over a short time frame, making it a critical target for climate change mitigation. It is primarily produced through natural processes like wetlands and human activities such as agriculture, fossil fuel extraction, and waste management.

High Temperatures

A catalyst is a substance that increases the rate of a chemical reaction without being consumed in the process, allowing reactions to proceed more efficiently and often under milder conditions. Catalysts are crucial in both industrial applications and biological systems, where they facilitate essential reactions that would otherwise occur too slowly to sustain life.

Industrial process

Carbon dioxide emissions, primarily from burning fossil fuels and deforestation, are the leading cause of climate change, contributing to global warming and ocean acidification. Mitigating these emissions is crucial for achieving international climate goals, such as those outlined in the Paris Agreement, to limit global temperature rise and its associated impacts.

Carbon Dioxide Emissions

Environmental impact refers to the effect that human activities and natural events have on the environment, encompassing changes to ecosystems, biodiversity, and natural resources. Understanding and mitigating these impacts is crucial for sustainable development and the preservation of ecological balance.
