Converting clean ammonia back into hydrogen

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.

Black Sea deal in danger

Last year, in the wake of Russia’s invasion of Ukraine and the associated disruption to fertilizer and grain exports from both countries, there were dire predictions of the impact upon global food supply. That the worst of these predictions have not so far come to pass is in no small part due to the deal brokered by the United Nations and Turkey in July 2022 to allow exports of grain and fertilizers from Black Sea ports. According to the UN, since last July, some 29.5 million tonnes of grain and foodstuffs have been exported from Ukraine via the Black Sea, including nearly 600,000 tonnes in World Food Programme vessels for aid operations in Afghanistan Ethiopia, Kenya, Somalia and Yemen. Before the war, Ukrainian grain fed the equivalent of up to 400 million people worldwide, and the deal ensured that Ukrainian grain exports ‘only’ fell by 5 million t/a over the past year.

Innovative gas scrubbing at SSP plants

Single superphosphate (SSP) is relatively easy and cheap to make. Yet traditional gas scrubbers often limit production and create plant maintenance issues.Fortunately, an innovative scrubbing technology developed by Armatec Environmental can overcome many of these problems. Based on high efficiency void towers, this new approach helps SSP producers meet stringent global emissions standards, explains Armatec’s Shane Pope , while simultaneously maximising production and improving worker conditions.
