Renewable energy Green hydrogen Global green molecules

Green molecules for a cleaner global economy.

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

Turning renewable energy into molecules the world can use.

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

Renewable energy, converted into chemistry.

Green molecules are fuels and industrial chemicals produced using renewable energy and low-emissions hydrogen instead of conventional fossil-based feedstocks wherever technically feasible.

01

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.

02

Green methanol

Renewable hydrogen combined with a sustainable carbon source to create a liquid molecule suited to chemical and marine-fuel value chains.

03

Sustainable fuels

Renewable hydrogen can support synthetic fuel pathways, including sustainable aviation fuel, for transport modes where direct electrification is difficult.

Hard-to-abate

Industrial decarbonization

Hydrogen-derived fuels and feedstocks can address industrial processes and transport segments where direct electrification is technically difficult or uneconomic.

Energy trade

Move renewable energy

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.

Food systems

Cleaner fertilizer inputs

Ammonia is the starting point for mineral nitrogen fertilizers. Replacing fossil-derived hydrogen with renewable hydrogen can reduce production-related emissions.

Agriculture

Green fertilizer

Lower-carbon ammonia can reduce the production footprint of nitrogen fertilizer.

Maritime

Marine fuels

Green methanol and low-emissions ammonia are being developed as options for lower-carbon shipping.

Aviation

SAF pathways

Renewable hydrogen can support synthetic aviation-fuel pathways for long-haul transport.

Industry

Clean feedstocks

Renewable molecules can replace fossil-derived feedstocks in selected chemical and industrial processes.

Our first molecule

Green ammonia. Built from renewable energy.

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

Essential to the world economy. Expensive for the climate.

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.

182Mt / year

Global ammonia production reported for 2022.

Why green ammonia matters

Change the hydrogen. Change the production footprint.

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

If conventional ammonia were replaced by green ammonia

Today's production scale 225 Mt potential direct CO₂ avoided / year
2050 existing-market scenario 412 Mt illustrative direct CO₂ avoided / year

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

One molecule. Multiple possibilities.

01

Green Fertilizer

Green Ammonia can support the transition toward lower-carbon fertilizer production.

02

Clean shipping

Green Methanol is being explored as a potential low-carbon fuel for the maritime industry.

03

Clean Aviation

Sustainable aviation fuel from green hydrogen is a potential low carbon fuel for the aviation industry.

04

Hydrogen carrier

Ammonia can enable hydrogen to be transported and utilized through an established chemical pathway.

Technology

Seven stages between sunlight and a delivered molecule.

Each stage below uses established industrial technology. What changes in a green pathway is the energy that drives it.

Stage one

Solar energy

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

Electrolysis

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.

H₂O + ELECTRICITY H₂ O₂

Stage three

Green hydrogen

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

Nitrogen separation

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

Ammonia synthesis

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

Storage

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

Distribution

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.
