# Siemens and Shomax partner to build off-grid green ammonia plant in Texas

Publication Date: 04.06.2026, 09:00

The off-grid NitroLEAF process skips natural gas entirely, which Shomax says can cut a grower's nitrogen costs by roughly 49%.

Siemens has signed a memorandum of understanding with Shomax Energy to develop new greenfield zero-carbon green ammonia fertilizer production in north Texas, a move aimed at cutting U.S. reliance on imported nitrogen, which covers about 18% of domestic supply.

The fertilizer, branded NitroLEAF, is made via off-grid renewable electrolysis without natural gas, which Shomax says insulates its pricing from fossil-fuel swings. Siemens will contribute power distribution, network architecture, process automation, and digital twin design to speed construction and lower capital costs.

In a June 2025 field trial near Wichita Falls, NitroLEAF raised winter wheat yield and application volume, according to Shomax, which estimates the product cuts a grower's nitrogen costs by roughly 49%, or about $40 per acre at prevailing prices.

Irfan Verjee, CEO of Shomax Energy, said Siemens' expertise would "accelerate our build-out and drive down capital costs" as the company scales NitroLEAF. The partners framed the plant as a template for distributed, made-in-America fertilizer production.

Neither company disclosed the facility's planned capacity, investment, or start-up date. The collaboration lands as U.S. nitrogen prices stay elevated, with anhydrous ammonia averaging above $1,100/t in Illinois in mid-May.
