Hydrocarbon-based production of ammonia carries an unavoidable carbon footprint. But one of the best methods for mitigating that footprint is already here: ultra-low carbon-intensity ammonia production, also known as “blue” ammonia. With blue ammonia production, a typical ammonia plant can sequester or repurpose game-changing volumes of carbon dioxide that would otherwise end up in the atmosphere. To help foster an optimal understanding of the benefits, Ameet Kakoti and Per Juul Dahl of Topsoe A/S provide an overview of the technologies that can help any ammonia operation achieve and maintain sustainable operations – sooner rather than later.

Paz Muñoz and Carmen Perez of Stamicarbon discuss the strategic selection of future-proof technology for nitric acid plants. To produce nitric acid in a feasible and sustainable way, manufacturers must carefully choose the right technology and consider the capex and opex involved in the production process to ensure long-term profitability.

Horisont Energi has the aspiration to develop the most carbon and energy efficient blue ammonia plant in the world, an environmentally friendly plant with a focus on sustainable solutions. This article describes the main features of the Barents Blue Ammonia project, such as 99% carbon capture rate target, a high degree of modularisation, winterisation, infrastructure for ammonia and CO2 management and the provision for future expansion.

Highly efficient ammonia synthesis and subsequent cracking to hydrogen are key processes in the transition to the green hydrogen economy. Catalysts play an important role in the ammonia cracking process. Clariant offers both nickel and precious metal catalysts for this application and research on robust catalysts that allow lower temperatures for increased energy efficiency is ongoing.

Technological innovation is vital to solving the global food challenge and delivering the transition to a low-carbon economy. Pejman Djavdan, Stamicarbon’s CEO, sets out his vision for a future-proof fertilizer industry – one that will enable the sustainable intensification of agriculture while also protecting the environment.

Despite being an age-old industry, the phosphate sector remains vibrant and driven by a passionate commitment to leaving behind a sustainable world for future generations. Tibaut Theys, general manager of Prayon Technologies, explains how the industry, by implementing more efficient production processes and promoting responsible fertilizer usage, is working urgently to reduce CO2 emissions, as well as striving to minimise its environmental footprint.

The recovery of waste heat from Aurubis’ copper smelting operation in Hamburg is already helping to reduce global carbon emissions and has the potential to provide heat for up to 20,000 homes through the district heating network in Hamburg’s HafenCity. The energy for the network comes from waste heat that Aurubis recovers from their sulphuric acid plant, using unique Alfa Laval plate heat exchanger technology.

Pejman Djavdan , CEO of Stamicarbon looks at the ways in which the fertilizer industry must grapple with issues such as decarbonisation, sustainability and more efficient use of nutrients.

Gasification, particularly of waste and biomass, is seeing interest as sustainable sources of syngas. But there are both technical and commercial challenges to wider adoption.

Advances in clean hydrogen and ammonia production is fuelling worldwide interest in a new market for hydrogen and ammonia to provide a reliable low-carbon energy future. Ammonia cracking, the dissociation of ammonia back into hydrogen, delivers a pathway to large-scale sustainable hydrogen production. In this article KBR, Johnson Matthey, thyssenkrupp Uhde, Duiker, Proton Ventures and Casale report on their technologies and approaches to ammonia cracking in a low carbon economy.
