THE SHELL BLUE HYDROGEN PROCESS

via electrolysis has a similar efficiency to blue hydrogen production, but the levellised cost of production is significantly higher for electrolysis at €66/MWh compared with €47/MWh for SMR–CCUS [Ref 9]. In addition, it is widely acknowledged that scaling up blue hydrogen production will be easier than delivering green hydrogen.

On the climate impacts of blue hydrogen production

1. Introduction Hydrogen is foreseen to be an important energy vector in (and after) the transition to net-zero Greenhouse Gas (GHG) emission economies. 1–6 The prerequisite is that its production results in very low GHG emissions, such that the overall process of hydrogen production and use could be made net-zero with a feasible level of carbon …

Production

CCUS enabled – Commonly referred to as "blue hydrogen", CCUS enabled hydrogen is commonly produced via a process called reforming.This process reacts steam with a stream of natural gas at high temperatures to create hydrogen and carbon dioxide. The capture of carbon dioxide (CO 2) is required to make this a low carbon form of hydrogen …

Q&A: Affordable blue hydrogen production with Shell Blue Hydrogen Process

Shell is already developing both green and blue hydrogen production. Whilst green hydrogen is the ideal aspiration for a low-carbon energy future, that technology has a number of years to go before it is of a competitive price range. In the interim, blue hydrogen can help create the demand and transport networks for hydrogen whilst green ...

The hydrogen colour spectrum

Currently, this is the most common form of hydrogen production. Grey hydrogen is created from natural gas, or methane, using steam methane reformation but without capturing the greenhouse gases made in the process. Grey hydrogen is essentially the same as blue hydrogen, but without the use of carbon capture and storage. Black …

Blue hydrogen must be done properly

In summary, producing blue hydrogen properly implies sourcing feed gas with minimum GHG intensity from the production, processing, and transport of natural gas. Also, sourcing of electric power input is needed from a low CO 2 intensity grid or from dedicated low carbon electricity generation.

Shell Blue Hydrogen Process

Blue hydrogen refers to hydrogen that is produced from fossil fuels with applied carbon capture and storage technologies (CCS) to limit the carbon intensity of the process. Blue H 2 sometimes is referred to as low-carbon hydrogen. Without low-carbon hydrogen, it will be difficult to decarbonise hard-to-abate heavy industry and achieve ...

blue hydrogen production

Steam reforming is a principal industrial process used to manufacture synthesis gas (syngas) for the production of hydrogen, ammonia and methanol. The heart of the process is the tubular primary reformer in which hydrocarbon feed (e.g., methane) reacts catalytically with steam to form a mixture of H 2, CO and CO 2 .

The term "Blue Hydrogen" refers to hydrogen generation processes that minimize CO 2 emissions. The CO 2 emissions are reduced via absorption from the hydrogen rich process gas (pre-combustion CO 2 Capture) or the reformer flue gas (post-combustion CO 2 Capture). The absorption is typically accomplished with an amine based solvent, but …
