There is an increasing need for industry to transition toward more sustainable and low-carbon solutions, and green H₂ is emerging as an alternative thermal source in this scenario. When used as a fuel in steam crackers, H₂ has the potential to eliminate CO₂ emissions.

Fired heaters, reformers and olefin furnaces (referred to collectively as heaters) are critical assets in the hydrocarbon and petrochemical processing industries (HPI). Refractory linings, structures and associated materials play a vital role in protecting exterior steel casing from high temperatures, flames and corrosive combustion gases, reducing thermal energy losses and fuel consumption. 

While the concept is simple, H₂ blending poses several chemical, logistical and control challenges. This article discusses the benefits and challenges associated with H₂ blending and provides process measurement solutions.

Pipelines are a highly cost-effective method of transportation, and existing pipeline infrastructures are being assessed for their suitability to transport H₂ around the globe, blended within natural gas transport or as pure H₂.

Ammonia (NH₃) is emerging as one of the most promising H₂ carriers, offering solutions to several critical challenges associated with H₂ storage and transportation. As H₂ is increasingly recognized as a pivotal component in the transition to a carbon-free energy future, efficient storage and transportation systems have become crucial for its widespread adoption.

To establish a sustainable global green hydrogen (H₂) market, offtake agreements—which determine the sale, purchase and supply of green H₂ and its derivatives—are paramount.

In 2024, important progress was made in the hydrogen (H₂) sector in Spain. The revised version of the National Energy and Climate Plan (NECP, or PNIEC in Spanish) was released, significantly increasing ambitions for renewable technologies.
