The BayoTech page on Carbon Intensity discusses various aspects of hydrogen production and its associated carbon emissions:
Color and Carbon Intensity: Hydrogen, a clean fuel, results in no emissions other than water when consumed. However, the production and delivery processes of hydrogen contribute to carbon emissions. The carbon intensity of hydrogen production methods varies widely, influenced by factors like energy consumption, transportation, liquification, and feedstock source.
Misleading Color Associations: Hydrogen production methods are often oversimplified and represented by colors based on their source molecule. These colors reflect the emissions profile at generation but don't account for the entire transportation process to the hydrogen's use point. Considering the entire value chain, the carbon intensity presents a more complex and varied picture, challenging long-standing beliefs in the hydrogen sector.
Carbon Intensity Factors: Overlooked factors affecting carbon intensity in hydrogen production and transportation include the source of electrical power for electrolysis. For instance, if electrolysis is powered by a grid with significant fossil fuel energy, it results in higher carbon impact. Despite being associated with "green hydrogen," electrolysis can be inefficient and contribute to greenhouse gas emissions.
Potential for Carbon Negative Production: BayoTech’s on-site hydrogen production using reformer technology can lower carbon intensity compared to electrolysis using less renewable electric grids or central hydrogen production plants. Using biomethane sources, such as animal waste and landfill gas, for hydrogen production can significantly reduce carbon impact, potentially leading to negative carbon intensity in hydrogen production with BayoTech’s technology.
