Green Ammonia Plant

Key Components of a Green Ammonia Plant

Renewable Power Supply: Dedicated solar farms, wind farms, or a hybrid combination provide the electricity needed for electrolysis.

Alkaline Water Electrolysis Units: Modular systems that offer high efficiency and scalability, with capacities typically ranging from several MW to over a GW.

Hydrogen Storage: Buffering mechanisms ensure continuous operation of the ammonia synthesis unit, even when renewable power supply fluctuates.

Ammonia Synthesis Section: Advanced catalytic reactors transform the hydrogen and nitrogen feedstock into ammonia under controlled conditions.

Ammonia Storage and Distribution: Liquid ammonia is safely stored in cryogenic tanks and can be transported for use as fertilizer, a hydrogen carrier, or clean fuel.

Energy & Mass Balance Overview

This tool calculates the core process parameters for a green ammonia plant powered by renewable electricity. Based on the input power to the electrolysis plant (in MW), it estimates the production rates of key products and utilities required throughout the value chain:

⚡ Input

Power to Electrolysis Plant: The total electrical capacity feeding the electrolysis unit, typically sourced from renewable energy (e.g. solar, wind, hydro).

🧪 Electrolysis Output

• Produced Dry Hydrogen (Nm³/h): Hydrogen generated from water electrolysis.

• Produced Oxygen (Nm³/h): Oxygen is released as a byproduct during hydrogen production.

🧬 Ammonia Synthesis Inputs

• Required Nitrogen for Haber-Bosch (Nm³/h): Nitrogen feed for ammonia synthesis, typically generated from air separation.

• Required Water (t/h): Total water needed for electrolysis.

• Required Cooling Water (t/h): Cooling water to manage electrolysis thermal load.

🌱 Final Products

• Produced Liquid Ammonia (t/h): Amount of NH₃ synthesized through the Haber-Bosch process.

• Tail Gas to Flare (Nm³/h dry): Unreacted or purge gases, usually containing hydrogen and ammonia, sent to a flare or recovery unit.
