Yara opts for mass balance approach to low-carbon ferts
Norwegian fertilizer giant Yara is employing an internal mass balance mechanism to distribute its production of low-carbon and renewable ammonia towards finished fertilizer production.
Under the mechanism, referred to as Yara's Ammonia Transfer System, ammonia produced by Yara with a lower carbon footprint — either from renewable electricity and electrolysis or by using natural gas and carbon capture — will be handled and treated in the same manner as Yara's fossil fuel-based ammonia production. With no physical distinction between the two types of molecules, both will be held in the same tanks.
A thorough in-house carbon accounting system, referred to by Yara as Carbon Watch, will monitor overall carbon emissions from all of Yara's production ensuring that the firm is not selling more low-carbon final products than the low-carbon or renewable ammonia it has produced.
Yara will offer consumers fertilizer products made from its low-carbon ammonia with a statement of verified carbon intensity. The finished product could contain any percentage mix of renewable, low-carbon or fossil fuel-based ammonia feedstock, but the carbon intensity reduction allocation across all products will match the carbon intensity reduction achieved from Yara's low-carbon or renewable production assets. The Ammonia Transfer System and Carbon Watch have both been validated by Norwegian classification society DNV.
Yara produces renewable ammonia from its Porsgrunn plant in Norway, which it commissioned at the end of 2023 and is ramping up to 20,000 t/yr this year. Yara has also reached a final investment decision on its carbon capture and storage expansion project at its Sluiskil plant in the Netherlands, where up to 800,000 t/yr of CO2 could be captured and stored by 2026. Production from both plants will be included in the mass balance structure.
At present, Yara is applying the Ammonia Transfer System exclusively to its own production, but the firm may extend it to third-party supply in the future.
Yara has a 100,000 t/yr offtake agreement with Indian renewable energy firm Acme for renewable ammonia from its planned plant in Oman, which could supply Yara with low-carbon ammonia from 2026. The third-party supply could potentially be included in Yara's carbon accounting, the company said. The approach is being applied to finished fertilizers produced with low-carbon ammonia so far, but could be implemented for other end uses in the future.
The mass balance method avoids incurring additional emissions and costs from transporting and storing low-carbon molecules separately. This is particularly important in the fertilizer industry, where affordability is essential. It also enables low-carbon product to be phased in using existing infrastructure.

US amsul stripping margin rises again in April
US amsul stripping margin rises again in April
Houston, 19 April (Argus) — The stripping margin for ammonium sulfate (amsul), driven by higher amsul prices, continued to rise in April even as variable costs grew. The stripping margin increased by nearly $24/st to $270/st for April, up by 10pc from March and up by 13pc from April 2023. Inland amsul trade exceeded $400/short tons (st) this month on continued supply tightness following production outages in the first quarter. Minimal length at New Orleans (Nola) spurred sellers to offer imported tons as high as $405/st fob for first half May delivery. Participants in the amsul market anticipate values to keep rising into May as supply tightness persists. Higher amsul prices have been partially caused by higher costs for inputs. The Tampa, Florida, ammonia contract rose by 7pc to $475/st in April from the month prior and the sulfur Tampa contract climbed by 17pc to $81 per long ton (lt) from the previous quarter. The cost of ammonia and sulfur were 8pc and 27pc lower than a year earlier, respectively. The total variable cost for amsul rose by $10/st in April to $143/st after holding steady in March. Rising ammonia prices have supported amsul variable costs but gains in the price of ammonia have not been as substantive as the market expected, sources said. Applications of ammonia in the US are slowing, which may weaken the price of the Tampa contract, but production outages could offset seasonal declines. Ma'aden's ammonia II plant is due to undergo a month of maintenance starting mid-April. Sulfur prices are expected to remain firm in the near term but lose momentum entering the third quarter on higher refinery utilization in the US and the return of Chinese exports of MAP and DAP, which could oversaturate the phosphate fertilizer market. Sulfuric acid is used to produce DAP and MAP. By Meghan Yoyotte Send comments and request more information at feedback@argusmedia.com Copyright © 2024. Argus Media group . All rights reserved.
Phosphates: Indian DAP stocks build in March
Phosphates: Indian DAP stocks build in March
London, 19 April (Argus) — DAP stocks rose by the equivalent of 2-3 import cargoes in March, or nearly 86,000t, as imports and local production outstripped offtake. Indian DAP production reached 218,900t in March, according to FAI data, down nearly 41pc on the same month in 2023. DAP imports reached 201,000t in March, down nearly 54pc on March 2023. Sales of DAP reached 334,200t, down nearly 12pc year on year. Stock draw/build, defined as production plus imports minus offtake, was plus 85,700t. This implies that stocks are still close to 2mn t of DAP, as estimated by the Indian government. Full fertilizer year DAP production (April 2023-March 2024) reached 4.29mn t, down around 1pc year on year. Imports were down 15.4pc at 5.57mn t, mainly due to the loss of supply from China owing to customs inspections, with sales at 10.8mn t, up nearly 4pc year on year.

EPS to register six ammonia-powered newbuilds with SRS
EPS to register six ammonia-powered newbuilds with SRS
London, 17 April (Argus) — Shipping firm Eastern Pacific Shipping (EPS) will register six dual-fuel ammonia powered vessels, due to be delivered from 2026, with the Singapore Registry of Ships (SRS). The commitment is part of an initial agreement with Singapore's Maritime and Port Authority (MPA), vessel classification organisation American Bureau of Shipping (ABS) and Lloyd's Register. EPS said the collaboration with the MPA will extend to supporting crew and seafarer training on the vessels powered by "zero and near-zero emission fuels", in addition to pilot trials of these fuels, and building on the capacity and infrastructure required for ammonia bunkering. Argus assessed the price of green ammonia dob east Asia on a very-low sulphur fuel oil energy density equivalent (VLSFOe) at $2,608.90/t in March, a premium of over $1,975.08/t against VLSFO dob Singapore. Grey ammonia in east Asia was assessed at an average of $829.52/t VLSFOe across March, a premium of $195.70/t to VLSFO dob Singapore.

Singapore's MPA, IEA unite on maritime decarbonisation
Singapore's MPA, IEA unite on maritime decarbonisation
Singapore, 17 April (Argus) — The Maritime and Port Authority of Singapore (MPA) and the IEA have signed an initial deal to push the transition to zero and near zero emission fuels, while working on technology as well as digitalisation to meet the maritime decarbonisation agenda. The agreement, signed by MPA chief executive Teo Eng Dih and IEA executive director Faith Birol, was announced at the Singapore Maritime Week 2024 (SMW) this week. "Greater international collaboration in maritime and energy industries is critical for international shipping to meet international decarbonisation goals," Teo said. "Shipping is one of the hardest sectors to decarbonise and we need to spur development and deployment of new technologies to slow and then reverse the rise in its emissions," said IEA chief economist Tim Gould. "This will require strong collaboration at a national and international level." Training programmes will be built to support the adoption of new fuels. There will also be partnerships made towards fuel-related projects and initiatives such as the International Maritime Organisation-Singapore NextGen project. The IEA plans to open its first regional co-operation centre in Singapore, which will be its first regional office outside of its headquarters in Paris, France.
