Carbon Recycling International (CRI), which operates a geothermally powered green methanol plant at Svartsengi, 40km southwest of Reykjavik, had to evacuate its site in late November when a 3km fissure opened in the earth a few kilometres away and lava began spilling across adjacent land. Satellite photos of the area taken on November 24 show a large field of molten and cooled lava to the north, west, and south of Svartsengi, though the plant itself remained undamaged. CRI’s Iceland facility runs on CO2 , water, and renewable electricity from the Svartsengi geothermal power station. CRI says the low-carbon energy source allows it to produce 4,000 t/a of methanol with a greenhouse gas footprint just 10–20% that of conventional methanol.

Protectionism casts a shadow over the new year

The start of a new year is a traditional time to take stock of the previous 12 months and look ahead to the next. In this regard, CRU’s most recent annual client survey, conducted at the end of December last year, makes interesting reading as to your own concerns for 2025 and beyond. There were numerous responses across commodity and financial sectors, and broadly based worldwide, if slightly skewed towards Europe and North America, but across all of these the key worry for the coming year clearly emerged as trade tariffs and protectionism. This is perhaps unsurprising, given incoming US president Donald Trump’s avowed intent to impose blanket 20% tariffs on all goods entering the US, and up to 60% on China. While most clients did not think tariffs would rise as much as some of Trump’s rhetoric might suggest, most expect rises of 5-10% across the board, and Asian businesses are most concerned. CRU’s most recent position paper on US tariffs highlights some of the internal political and legal challenges in implementing these, but does acknowledge that some rises will be inevitable, and may well produce the kind of reciprocal measures last seen in the previous Trump administration’s trade war with China and the EU in 2018.

Conversion into hybrid ammonia plants

One challenge of a green revamp by stepwise injection of green hydrogen into existing ammonia/urea complexes is to cover the nitrogen demand for the ammonia synthesis while stepwise reducing the front-end load, usually by applying a cost-intensive air separation unit (ASU). thyssenkrupp Uhde GmbH has developed an advantageous concept whereby, instead of an ASU, the nitrogen gap is closed by the introduction of pretreated reformer flue gas back into the ammonia process, with the side effect to also enhance CO2 production.

Making RFNBO compliant ammonia competitive

One of the key challenges of producing RFNBO (renewable fuels of non-biological origin) compliant ammonia is managing the intermittency associated with renewable energy sources for hydrogen production. Furthermore, the additional costs associated with managing this intermittency can be significant. In this article, Dr Solomos Georgiou of AFRY Management Consulting explores those additional costs as well as potential ways to achieve cost savings and make RFNBO-compliant ammonia production competitive against conventional ‘grey’ ammonia.
