U.S. green hydrogen producer Avina Clean Hydrogen has finalized the front-end engineering design (FEED) and front-end loading (FEL-3) for its clean ammonia facility, which will produce 2,200 metric tons per day (MTPD) and is situated on the Texas Gulf Coast.

The FEED scope included the engineering design of the ammonia synthesis loop, hydrogen and ammonia storage, electrolytic hydrogen production, renewable power integration, and the engineering design of outside battery limits (OSBL) facilities.

As announced, the overall FEED effort was spearheaded by Indian conglomerate Larsen & Toubro (L&T), which provided its engineering, procurement, and modularization expertise to assist in the project's design and estimation. U.S. construction contractor EXCEL led the constructability efforts during FEED, drawing on its experience in building similar ammonia plants in the Texas Gulf Coast area.

Additionally, the FEED process involved collaboration with electrolyzer manufacturers and renewable energy suppliers to enhance the plant design. U.S. engineering firm KBR had previously supplied the basic engineering design (BED) package for the facility and continued to support design activities.

Aiming for a final investment decision (FID) in 2025, the clean ammonia facility is projected to begin operations in 2028. It is anticipated to produce up to 800,000 metric tons per annum (MTPA) of clean ammonia by utilizing a combination of blue and electrolytic hydrogen. Avina has stated that the facility will meet renewable fuels of non-biological origin (RFNBO) standards, in accordance with European Union (EU) regulations.

Notably, Avina has secured a long-term water supply agreement with the local water district, guaranteeing adequate water access for clean ammonia production. Additionally, interconnection studies have been completed to confirm access to 1 GW of transmission capacity. The facility will also benefit from the extensive network of pipelines, storage, and terminal facilities managed by oil and gas sector players in the Texas Gulf Coast region.
