Air Liquide SA plans to start up its first pilot ammonia cracker at Antwerp, Belgium in the first quarter of 2025, as per company.
“We will have the first pilot unit started in Q1 2025 that will be the first of its kind in Belgium,” said Emilie Mouren-Renouard, Air Liquide’s CEO of the Europe, Africa, Middle East and India Industries Hub, speaking Dec. 4 in a panel discussion at the Gulf Petrochemicals and Chemicals Association (GPCA) 18th Annual Forum, being held in Muscat, Oman.
“We have developed the technology process [for] ammonia cracking to convert it back to green or blue hydrogen in those geographies where there is demand,” she said in the panel session focused on sustainable solutions for the chemical industry.
Air Liquide announced in March 2023 that it would build the pilot ammonia cracker at the port of Antwerp, with the plant originally planned to be operational in 2024. The unit’s initial capacity was not given.
According to Air Liquide’s website, the ammonia cracking process uses the company’s proprietary next-generation reactor tubes heat-integration technology, which allows for the “highest possible ammonia-to-hydrogen conversion yield and zero direct CO2 emissions.” Under Advance, the company’s strategic plan, Air Liquide has committed to globally investing about €8.0 billion in the low-carbon hydrogen value chain by 2035.
Mouren-Renouard said the ability to quickly develop pilot units and gain experience from their initial operations is “absolutely key if we want to build at scale, critical mass, and at the end of the day, we want to reduce the cost.”
She referenced the Middle East’s growing number of announced projects for the production of blue and green ammonia, all being developed primarily for export markets such as Europe and Asia.
Mouren-Renouard also said that Air Liquide is seeing “real demand” for more circularity not only from the chemical industry but also other hard-to-abate industrial sectors such as the cement, lime and steel industries. Carbon capture and sequestration (CCS) technology will be key to achieving this, she said, with CCS “very relevant” for hard-to-abate sectors that are not able to relocate their plants and which would be unable to achieve lower emissions if the solution is not available. “We see demand picking up in all those hard-to-abate sectors,” she said.
Also speaking on the same GPCA panel, Ed Sparks, CEO of W.R. Grace, and Narongsak Jivakanun, CEO of Thailand’s PTT Global Chemical, flagged circularity challenges related to the recycling of waste plastics.
“The real challenge that we see — the tough nut on circularity — is how do you move beyond the limits of mechanical recycling, which are not going to be sufficient to meet targets for the recycling of plastics, and how do you make advanced chemical recycling real, affordable and scalable quickly?” Sparks said.
Pyrolysis is a “great first step and a viable solution in the near term,” he said. However, longer term, he said the real opportunity will lie in creating higher-value products from advanced chemical recycling. Grace is currently at pilot scale with its own advanced recycling solution, he said.
One of the biggest challenges for plastics recycling and the processing of waste oils is the “variability of feedstocks,” Sparks said. “How can you design processes that can span that variability and solutions that don’t require you to have a pure feedstream, because it won’t be.” Evolving the relevant supply chains is incredibly challenging, he noted, adding that “what it means is a robustness in process technologies and an ability to be able to handle those impurities and still make top-level products. I think that’s one of the real challenges.”
PTTGC’s Jivakanun said technology, however, is not the only challenge. On a waste plastics mechanical recycling project the company is developing, he said the issue was not technology, the end product, its certification or the end market. “People want to use it. The bottleneck is the raw material.”
Despite working closely at community and household levels and organizing more than 300 drop points, Jivakanun said this is “still not enough ... it’s not just technology anymore, it’s how do we create a supply chain. We’re going through the same exercise with our sustainable aviation fuel program that will be starting up next year. Those are the challenges, and it’s real.”
We remind, Air Products and Chemicals Inc. (Allentown, Pennsylvania) has issued a letter to shareholders urging them to support the company’s board nominees over the nine nominations proposed by activist investor Mantle Ridge (New York). The company criticized Mantle Ridge’s campaign as a “reckless desire for short-term gain at the expense of other shareholders.” Air Products has scheduled its 2025 annual meeting for Jan. 23, 2025.
