NextChem to conduct study on SAF plant

NextChem subsidiary MyRechemical has been awarded an engineering study contract by Altalto Ltd. for a sustainable aviation fuel (SAF) plant in Immingham, Lincolnshire, based on its proprietary NX CircularTM gasification and NX CPOTM technologies. Altalto is a company set up by Velocys to develop SAF projects in the UK. The plant is expected to be operational in 2030. Initial targets include the production of 23,000 t/a of SAF for the UK market. Feedstock will be sourced from residual municipal solid waste (MSW) and commercial and industrial waste. The project has been awarded a grant from the UK Department for Transport’s Advanced Fuels Fund to progress basic engineering design. MyRechemical will operate as a technology provider and as coordinator for other technological partners. It will also supply engineering services.

NX Circular gasification technology allows the plant to convert waste by generating syngas, which is subsequently transformed to syncrude through Velocys’ Fischer-Tropsch technology and upgraded to high-quality sustainable fuels. NX CPO technology produces synthesis gas via controlled partial oxidation through a very fast reaction, is contributing to maximising overall yield while minimising carbon intensity of the product.

Offtake agreement for fertilizer plant

ATOME says that it has signed a definitive offtake agreement with Yara for the purchase of the entire 260,000 t/a output of the low-carbon Villeta project. The plant will be based on 100% renewable baseload power, and will displace some 500,000 t/a of carbon dioxide equivalent. ATOME says that the agreement represents the last commercial milestone in its path to a final investment decision (FID), following the successful completion of other key commercial items, including the signing of the $465 million fixed-price, lump-sum engineering, procurement and construction contract with Casale.

HIP Azotara to be dismantled for data centre

The nitrogen plants at HIP’s Azotara site are to be dismantled and removed as part of plans to convert the site to a data storage facility. Plants to be removed include the urea plant and urea storage facility, the UAN liquid storage facility, the calcium ammonium nitrate and nitric acid plans, and thegrain storage societies. In addition, the entire Block 6 is planned to be removed, which includes ammonia plants and storage, nitric acid and urea production, all of which have been out of operation for a long time.

NextChem and Siemens to cooperate on maritime methanol fuel cells

NextChem and Siemens Energy have signed a memorandum of understanding to cooperate on the development and commercialisation of a high temperature methanol fuel cell, based on a newly designed modularised solution. With an initial focus on the high-end yachting segment, the target market for the cooperation is the maritime industry and beyond. According to the MoU, NextChem will focus on the design and supply of the methanol fuel cell module, while Siemens Energy will leverage its expertise in onboard system integration, complete electrification and energy management with the aim of delivering a complete solution to shipyards and owners.
