Project definition

Problem statement

Green ammonia can use renewable hydrogen with an established Haber-Bosch loop, or pursue more direct electrochemical and plasma-assisted nitrogen conversion. Published evidence spans different scales, metrics and measurement quality.

The engineering problem is to compare these routes on a common product boundary without presenting catalyst-scale performance, nominal electricity use or one favourable context as proof of complete plant readiness.

Project objectives

  • Compare alkaline, PEM and solid-oxide electrolysis coupled to Haber-Bosch with mild-condition, lithium-mediated, protonic, nitrate-reduction and plasma-assisted routes.
  • Evaluate energy, operational carbon, renewable flexibility, feed compatibility, materials, durability, purity, safety, scale, economics and measurement assurance.
  • Study central, wind, solar, distributed, nitrate-recovery and export contexts.
  • Compare direct following, hydrogen-buffered, battery-buffered and hybrid system configurations.
  • Test balanced, energy, flexibility and scale-readiness decision priorities.
  • Retain hard gates, uncertainty, sensitivity, workflow FMEA and an assurance crosswalk.

Project structure

Project components

01

Route register

Declares eight route archetypes with transparent process, energy, material, scale and evidence positions.

02

Context and system model

Crosses six production contexts with four operating configurations while preserving feed and scale constraints.

03

Decision model

Applies five hard gates and four transparent weighting scenarios to the retained evidence.

04

Uncertainty model

Runs 30,000 fixed-seed samples per route and retains percentile and threshold results.

05

Assurance model

Ranks 180 workflow FMEA cells and links route evidence to twelve assurance requirements.

Methodology

Project workflow

  1. 01
    Define the product boundary

    Nitrogen feed, hydrogen source, electricity, synthesis, separation, recovery, storage and product purity are declared.

  2. 02
    Build the comparison matrix

    Each route is evaluated across every retained context, system configuration and evidence state.

  3. 03
    Apply decision priorities

    Balanced, energy, flexibility and scale scenarios expose conditional rankings.

  4. 04
    Propagate uncertainty

    Fixed-seed sampling tests whether route positions persist when evidence values vary.

  5. 05
    Review validation gates

    Energy, carbon, feed, scale and measurement weaknesses remain visible beside weighted scores.

Demonstration scenario

Under the retained balanced inputs, electrolysis followed by flexible Haber-Bosch has the strongest industrial evidence. Direct electrochemical routes show modularity and response advantages but remain constrained by energy efficiency, lifetime, product recovery, measurement assurance and demonstrated scale. Nitrate reduction becomes competitive only where nitrate feed and recovery value are present.

Pandas retains complete case matrices, route summaries, scenarios, uncertainty, FMEA and assurance results.
Figures
Matplotlib generates twelve labelled route, context, energy, flexibility, uncertainty and risk figures.
Reproducibility
A fixed seed, explicit configuration, automated tests and Docker reproduce the study.
Documentation
The report covers synthesis fundamentals, route evidence, renewable integration, measurement, safety, lifecycle boundaries, methods, results and further work.

Testing

Evaluation

Evaluation measures

  • Energy intensity and operational carbon boundary
  • Renewable flexibility, minimum load and system compatibility
  • Nitrogen-feed compatibility, product purity and recovery
  • Materials, durability, safety, scale-up and economic evidence
  • Balanced, energy, flexibility and scale-readiness scenario rankings
  • Uncertainty intervals, sensitivity, hard gates, workflow FMEA and assurance completeness
  • Automated tests, accessibility audits, repository validation and container reproduction

Project boundaries

  • Inputs are literature-informed screening positions, not measurements from one operating plant.
  • Scores are not plant designs, cost quotations, safety cases, lifecycle certificates or investment recommendations.
  • Electricity source, capacity factor, feed availability, product purity, heat integration, storage and scale can change the comparison.
  • A site decision requires process simulation, complete balances, representative operating data, product testing, process safety review and qualified engineering assessment.
