Green ammonia
Renewable hydrogen combined with nitrogen from air. Today ammonia is indispensable to fertilizer production and may also serve as an energy carrier and maritime fuel.
Renewable energy Green hydrogen Global green molecules
GREEN MOLECULES is building a scalable platform for renewable industrial molecules — beginning with green ammonia and expanding toward green methanol and sustainable aviation fuels for global agriculture, industry, maritime and aviation markets.
Our approach
Convert renewable power into transportable, storable molecules for global industry.
GREEN MOLECULES combines renewable electricity, green hydrogen and proven synthesis technologies to create lower-carbon industrial molecules for sectors that are difficult to electrify directly.
Electricity is powerful but difficult to move across oceans or store for long periods. Green molecules such as ammonia and methanol can convert renewable energy into chemical form, making it easier to store, ship and use in industrial value chains.
Green molecules
Green molecules are fuels and industrial chemicals produced using renewable energy and low-emissions hydrogen instead of conventional fossil-based feedstocks wherever technically feasible.

Renewable hydrogen combined with a sustainable carbon source to create a liquid molecule suited to chemical and marine-fuel value chains.
Renewable hydrogen can support synthetic fuel pathways, including sustainable aviation fuel, for transport modes where direct electrification is difficult.
Hydrogen-derived fuels and feedstocks can address industrial processes and transport segments where direct electrification is technically difficult or uneconomic.
Hydrogen derivatives such as ammonia and methanol are easier to store and transport over long distances than gaseous hydrogen, creating a pathway for international renewable-energy trade.
Ammonia is the starting point for mineral nitrogen fertilizers. Replacing fossil-derived hydrogen with renewable hydrogen can reduce production-related emissions.
Lower-carbon ammonia can reduce the production footprint of nitrogen fertilizer.
Green methanol and low-emissions ammonia are being developed as options for lower-carbon shipping.
Renewable hydrogen can support synthetic aviation-fuel pathways for long-haul transport.
Renewable molecules can replace fossil-derived feedstocks in selected chemical and industrial processes.
Our first molecule
Green Ammonia is produced by combining green hydrogen — generated using renewable electricity — with nitrogen separated from the air.
It provides a pathway for renewable energy to become a storable, transportable molecule with applications across agriculture, Aviation, industry and emerging clean-energy markets.
The global ammonia challenge
Ammonia is fundamental to food production and industry, but conventional production is still overwhelmingly fossil-based. Green ammonia changes the hydrogen source — using renewable-powered electrolysis instead of fossil-derived hydrogen.

IEAWhy green ammonia matters
More than 70% of today's ammonia production uses natural-gas steam reforming, while much of the remainder relies on coal gasification. Renewable electrolysis can produce hydrogen without the direct fossil CO₂ emissions associated with those hydrogen-production routes.
IRENA reports that demand in existing ammonia markets could reach 333 Mt by 2050 in a 1.5°C scenario — before considering the full scale of potential new energy uses.
Interactive scenario
Illustrative calculation only. “Today” applies the IEA's 450 Mt direct-CO₂ baseline proportionally. The 2050 figure applies the same average direct emissions intensity to IRENA's 333 Mt demand scenario. It assumes the replacement route has zero direct operational fossil CO₂; it is not a lifecycle assessment and does not include electricity, construction, logistics, land use or downstream fertilizer-use emissions.
Why green ammonia
Green Ammonia can support the transition toward lower-carbon fertilizer production.
Green Methanol is being explored as a potential low-carbon fuel for the maritime industry.
Sustainable aviation fuel from green hydrogen is a potential low carbon fuel for the aviation industry.
Ammonia can enable hydrogen to be transported and utilized through an established chemical pathway.

About Green Molecules
Green Molecules is being promoted by high-net-worth individuals who are interested in investing in the green economy and contributing to sustainable development globally.
The company is committed to promoting green molecules across international markets. Its current development focus includes Africa and India, where strong renewable-energy resources, industrial demand and logistics can support competitive green-molecule production.
In India, the company has identified a potential coastal project location in Andhra Pradesh. The development strategy is to work with the State Government and Government of India, including applicable incentive frameworks, to create cost-efficient green-molecule production for domestic and export markets.
The first phase under development in Andhra Pradesh is envisioned as a 400,000-tonnes-per-year Green Ammonia project. Subsequent phases are intended to expand into other green molecules, including Green Methanol and Sustainable Aviation Fuel (SAF), together with associated downstream and supporting industries.
The company aims to build a scalable international platform that connects renewable-resource regions with global customers in agriculture, chemicals, maritime transport, aviation and other hard-to-abate industrial sectors.

Technology
Each stage below uses established industrial technology. What changes in a green pathway is the energy that drives it.
Stage one
Photovoltaic generation supplies the electricity that drives the entire chain. Andhra Pradesh receives high solar irradiance across most of the year, which makes it well suited to producing the large, steady volumes of renewable power that electrolysis requires.
Because solar output varies through the day, plant design has to account for how production ramps with available power — through sizing, storage, or grid balancing.
Stage two
An electrolyser passes renewable electricity through water, splitting it into hydrogen and oxygen. No carbon is involved in the reaction itself — the carbon intensity of the hydrogen is determined almost entirely by the electricity that powers it.
Stage three
The hydrogen produced by renewable-powered electrolysis is the key building block. It is buffered and conditioned to the pressure and purity that ammonia synthesis requires, so that the synthesis loop can run within stable operating conditions.
Stage four
Air is roughly seventy-eight per cent nitrogen. An air separation unit isolates it — typically by cryogenic distillation or pressure swing adsorption — giving a high-purity nitrogen stream at industrial volume from an effectively unlimited feedstock.
Stage five
Hydrogen and nitrogen are combined over a catalyst at elevated temperature and pressure — the Haber-Bosch process, which has produced the world's ammonia for over a century. Three hydrogen atoms bond with one nitrogen atom to form NH₃.
The chemistry is unchanged. The difference in a green plant is the origin of the hydrogen and the renewable power behind the process.
N₂ + 3H₂ → 2NH₃
Stage six
Ammonia is stored either refrigerated at low temperature or pressurised in vessels, under controlled conditions with continuous monitoring, detection and containment. Handling procedures follow recognised industrial safety standards, and design details will be published alongside the plant's engineering documentation.
Stage seven
The finished molecule reaches customers by road tanker, rail or vessel depending on volume and destination. Andhra Pradesh's port access on the Bay of Bengal supports both domestic supply and export routes toward emerging clean-energy markets.
Products
