AFC Energy has agreed to jointly develop a range of small to large-scale ammonia-to-hydrogen crackers with an undisclosed US industrial firm. Under the terms of a joint development agreement (JDA), UK-based AFC Energy will get its development costs paid back by the industrial partner. Once certain key project steps are completed, the partnership is expected to start generating significant revenue for AFC Energy, commencing in 2027.

Co-recovery of helium from natural gas streams has been the helium sourcing paradigm since the 1970s and the countries with the largest helium reserves are Qatar, US, Algeria, Russia and Australia. Armed conflict, international tensions, depleting reserves and planned or unplanned outages in these key locations have influenced the global helium supply and demand balance dramatically.

Before air separation and liquid nitrogen became prevalent, ammonia cracking was used to produce small amounts of nitrogen. However, as the potential of international hydrogen supply chains emerges, small-scale ammonia cracking will be required to convert ammonia into hydrogen at the point of use. Unlike pure hydrogen, gaseous or liquid, liquid ammonia is easy to store and transport due to its high energy density.

Oxygen has been at the heart of industrial gases since 1895, when Carl von Linde first liquefied air and separated it into its primary oxygen and nitrogen components. Oxygen will remain vital and play a pivotal role in the energy transition. Releasing heat from fuel gases requires a reaction with oxygen. This combustion is essential to yield high temperature heat for power generation and industrial processes.

The dominant path to green hydrogen is splitting ultrapure water using renewable electrical power in an electrolyser. For each kilogramme of green hydrogen produced, 9-10 litres of water are consumed by electrolysis. This equates to circa 200 litres of water per megawatt of electrolyser capacity. To generate that amount of ultrapure water, circa 1.5 times as much fresh water is required. And to generate desalinated fresh water, approximately twice as much seawater is required.

Stephen Harrison from sbh4 Consulting analyses the key role oxygen and ASUs are playing in tackling emissions in heavy industryScope 3 emissions take place in the supply chain to an iron or steel making facility. They are not directly emitted from the iron or steel making plant (scope 1) and neither do they account for emissions from power generation for the plant (scope 2). Production of green steel will require reduction in all categories of greenhouse gas emissions.

Stephen B. Harrison outlines developments in the fast-moving aviation sector as airlines seek alternative sustainable fuelsAbout 8 gigatonnes of carbon dioxide (CO2) are emitted by the global transport sector each year. Almost half of that is from cars. Just over a quarter from trucks, buses, and lorries. About one eighth from shipping, and another eighth from aviation.

Stephen Harrison explores the area of industrial gases integration with petrochemicals processing and outlines the roles of oxygen and CO2 in ethylene oxide productionEthylene oxide (EO) production is one of the best examples of deep integration between the petrochemical and industrial gases sectors. In the presence of a catalyst, oxygen reacts with ethylene to produce ethylene oxide and yields carbon dioxide (CO2) as a co-product.

Aviation carbon dioxide (CO2) emissions are one billion tonnes per year – similar to the total annual CO2 emissions from Germany or Canada. And aviation CO2 emissions are rising faster than other transport sectors. Green hydrogen can be produced from renewable electrical power. Blue, low-carbon hydrogen is produced from fossil fuels with permanent storage of the CO2 emissions. Sustainable aviation is in its infancy. The breadth of solutions is broad.

Before air separation and liquid nitrogen became prevalent, ammonia cracking was used to produce small amounts of nitrogen. Small-scale ammonia cracking will be required in the future in advanced energy systems to convert ammonia into hydrogen at the point of use. Liquid ammonia is easy to store and transport due to its high energy density. And it can conveniently be cracked back to hydrogen on-demand.
