"Blue" hydrogen – an energy source that involves a process for making hydrogen by using methane in natural gas – is being lauded by many as a clean, green energy to help reduce global warming.
Blue hydrogen, a common term for decarbonised hydrogen, is derived from the reaction between natural gas and steam. Examples of the processes used for this are the Shell Blue Hydrogen Process (SBHP), steam methane reforming
Blue hydrogen is produced using a process called ''steam reforming'', which uses steam to separate hydrogen from natural gas. This process does produce GHGs, but carbon capture and storage technologies capture and store those emissions.
"Blue hydrogen" production controls CO 2 emissions by applying carbon capture, utilization and storage (CCUS) technology to the existing gray hydrogen process. Performance improvement by identifying key performance-influencing factors of materials for each unit can be a valid approach to effectively solve the aforementioned issues.
Instead, it is captured and stored separately. Blue hydrogen is currently a more viable production option than gery hydrogen due to its lower environmental impact, rendering it as a more environmentally friendly option. However, carbon emissions into the atmosphere are not completely eliminated by the blue hydrogen process.
How does the production of blue hydrogen work? In principle, the production method of blue hydrogen is no different to grey hydrogen. The industrial ''steam methane reformers'' (SMR) or ''auto thermal reformers'' (ATR) that currently
The production of blue hydrogen can be broken down into several key steps: Steam methane reforming (SMR) or autothermal reforming (ATR): Natural gas, primarily composed of methane (CH4), is combined with steam to create a mixture of hydrogen (H2) and carbon dioxide (CO2).

Natural gas-based hydrogen production with carbon capture and storage is referred to as blue hydrogen. If substantial amounts of CO 2 from natural gas reforming are captured and permanently stored, such hydrogen could be a
Nan Liu : When we compare typical hydrogen manufacturing technologies, the Shell Blue Hydrogen Process has two key differences: Simplicity and reduced capex. Shell blue hydrogen technology is based on its use of Shell Gas POx (SGP) technology, which is
Inclusion of blue hydrogen is inevitable for the transition toward hydrogen economy. Oxygen-based processes are most efficient for greenfield blue hydrogen applications. Carbon intensity and thermal efficiency are crucial factors in blue H 2 technologies.
Blue hydrogen is based on the idea that the current processes used to produce hydrogen from fossil fuels could be coupled to CCS technologies to decrease most of their GHG emissions. While this
5 · Horisont Energi is a clean energy startup that produces blue hydrogen, carbon capture and storage (CCS), and ammonia. It produces blue hydrogen by converting natural gas into hydrogen and carbon dioxide (CO2). The startup captures CO2 and securely stores it in underground reservoirs. This patented process prevents CO2 from entering
Steam methane reforming (SMR) is widely used in the hydrogen production industry; however, a significant amount of CO 2 is released during this process. Several efforts have been made to produce low-CO 2 hydrogen (blue hydrogen) via SMR; however, the proposed solutions are not applicable to small-scale plants. Therefore, this
This method involves splitting water molecules (H2O) into hydrogen (H2) and oxygen (O2) using an electric current. Using renewable energy sources ensures that the production of green hydrogen has minimal to zero greenhouse gas emissions, making it a sustainable and environmentally friendly alternative. Production Process for Green
Blue hydrogen is based on the idea that the current processes used to produce hy- drogen from fossil fuels could be coupled to CCS technologies to decrease most of their GHG emissions.
A novel technological industrial blue hydrogen production process – the Industrial Sorption Enhanced Autothermal Membrane (ISEAM) process, with the potential to produce constant fuel cell grade hydrogen with a purity of 99.99%, regardless of upstream process upsets, has been modelled using an Aspen Plus simulator and MATLAB
June 28, 2021. 3 min read. Saudi Aramco bets on blue hydrogen exports ramping up from 2030. [Arabian Business] Saudi Aramco has outlined plans to invest in blue hydrogen as the world shifts away from dirtier forms of energy, but said it will take at least until the end of this decade before a global market for the fuel is developed.
Natural gas–based hydrogen production with carbon capture and storage is referred to as blue hydrogen. If substantial amounts of CO 2 from natural gas reforming are captured and permanently stored, such hydrogen could be a
Industrial consumers could more fully decarbonize feedstock emissions by switching to blue hydrogen, so that both process CO₂ and combustion CO₂ get captured, but a nearer-term solution is blue hydrogen with carbon capture from only the more CO₂-concentrated process stream.
Blue hydrogen production is relatively easy to scale up to meet demand, says Shell. Furthermore, when a CO 2 penalty of US$25–35/t is applied, blue hydrogen becomes more competitive against grey hydrogen. Shell''s new Shell Blue Hydrogen Process reduces the cost of hydrogen by 22% compared to processes currently on the
Blue hydrogen is produced using the same reforming process that is used to create grey, brown and black hydrogen, but the CO₂ that would ordinarily be released is captured and stored
The Shell Blue Hydrogen Process has the lowest carbon footprint and lowest levellised cost compared to other decarbonised hydrogen (blue hydrogen) production methods like steam methane reforming and autothermal reforming.

Processes of blue hydrogen production are reviewed. • Blue hydrogen can reduce the carbon emissions compared to natural gas. • Carbon emissions can be stored in depleted natural gas reservoirs.
5 · Hydrogen is labelled blue whenever the carbon generated from steam reforming is captured and stored underground through industrial carbon capture and storage (CSS). Blue hydrogen is, therefore, sometimes referred to as carbon neutral as the emissions are not dispersed in the atmosphere.
Blue Hydrogen: Not Clean, Not Low Carbon, Not a Solution 5 Executive Summary Blue hydrogen hype has spread across the U.S., spurred by the billions of dollars of government funding and incentives included in the 2021 Bipartisan Infrastructure Law (BIL) and the 2022 Inflation Reduction Act (IRA).
