The Color of Hydrogen - Why It Matters

Posted by Bray Dohrwardt | Jul 10, 2024 | 0 Comments

Hydrogen has gained significant attention as a clean and efficient energy source capable of powering various applications, from fueling vehicles to generating electricity. Regarding energy production, different types of hydrogen play crucial roles in meeting diverse energy demands. Let's delve into the various types of hydrogen used in energy production. You can go to the Department of Energy’s page to learn more about the many uses of hydrogen in the energy space. Also, look at the National Governors Association's article “Hydrogen As An Energy Source” for a deeper dive into the subject. Contact the Dohrwardt Law Firm to discuss how the firm can help your business with your energy contracting needs.

Hydrogen is a tasteless, colorless, odorless, but flammable gaseous substance and one of the most abundant chemicals in our universe. How hydrogen is produced determines its “color” and its various uses in the energy space.

Grey Hydrogen: Grey hydrogen is the most commonly produced type of hydrogen today. It primarily derives from natural gas through steam methane reforming (SMR). While it is widely used, grey hydrogen production produces significant carbon emissions, making it a less sustainable option than other types of hydrogen.

Blue Hydrogen: Blue hydrogen is produced through a process similar to grey hydrogen but with the implementation of carbon capture and storage (CCS) technology. This allows for capturing and storing carbon emissions generated during production, significantly reducing its environmental impact. Blue hydrogen thus presents a more sustainable alternative to grey hydrogen while utilizing the existing infrastructure for natural gas.

Green Hydrogen: Green hydrogen is derived from renewable sources through electrolysis, which uses electricity to split water into hydrogen and oxygen. This method ensures zero carbon emissions during production, making green hydrogen the cleanest and most environmentally friendly option. With the increasing availability of renewable energy sources such as solar and wind power, green hydrogen production holds enormous potential for powering a carbon-neutral energy future.

Turquoise Hydrogen: Turquoise hydrogen is produced using methane pyrolysis, which breaks down methane into hydrogen and solid carbon without releasing carbon dioxide. This approach offers a unique pathway to produce hydrogen while sequestering carbon in a solid form, thus contributing to carbon dioxide reduction efforts.

Pink Hydrogen: Pink hydrogen is an emerging type that uses nuclear energy to power electrolysis, resulting in hydrogen generation without carbon emissions. While adopting nuclear power for hydrogen production raises various considerations, it offers a high-carbon option for large-scale hydrogen production.

Each type of hydrogen used in energy production presents distinct advantages and challenges, influencing its suitability for various applications. As the energy industry prioritizes sustainability and decarbonization, expanding low-carbon and renewable hydrogen production methods is expected to play a pivotal role in transforming the global energy landscape. By understanding the unique characteristics of each hydrogen type, stakeholders can make informed decisions to drive the transition towards a more sustainable and cleaner energy future.
