H2U Eyre Peninsula Gateway Hydrogen Project Begins Largest Green Ammonia Plant

The title of this post, is the same as that of this article on Hydrogen Fuel News.

  • South Australia will be creating the largest green ammonia plant in the world.
  • It will make 40,000 tonnes of green ammonia every year.
  • The plant will be powered totally by renewable energy.
  • At its heart will be a 75 MW hydrogen electrolyser.

This paragraph sums up the main objective of the plant.

According to Dr. Attilio Pigneri, H2U CEO, the project will play an important role in the ongoing development of the emerging green hydrogen and green ammonia markets.

It appears a lot of the green ammonia will be exported to Japan.

What Is Green Ammonia?

It is just ammonia produced by renewable energy. This is the first paragraph of the Wikipedia entry for ammonia.

Ammonia is a compound of nitrogen and hydrogen with the formula NH3. A stable binary hydride, and the simplest pnictogen hydride, ammonia is a colourless gas with a characteristic pungent smell. It is a common nitrogenous waste, particularly among aquatic organisms, and it contributes significantly to the nutritional needs of terrestrial organisms by serving as a precursor to food and fertilizers. Ammonia, either directly or indirectly, is also a building block for the synthesis of many pharmaceutical products and is used in many commercial cleaning products. It is mainly collected by downward displacement of both air and water.

It is a very useful chemical compound and it is now being developed as a zero-carbon fuel, as I wrote in The Foul-Smelling Fuel That Could Power Big Ships.

It can also be used as a refrigerant.

One of the most amazing pieces of engineering, I ever saw was a very old barn, where a farmer stored vast tonnages of apples. It was kept cool, by a refrigeration plant certainly built before the Second World War or possibly even the First, which used ammonia as the refrigerant.

Now that’s what I call engineering!

The Foul-Smelling Fuel That Could Power Big Ships

The title of this post, is the same as that of this article on the BBC.

The article talks in detail about using liquid ammonia to power large ocean-going ships.

  • A research project is underway in Copenhagen.
  • The ammonia would be green ammonia produced by renewable energy.

The aim is to seriously reduce emissions of greenhouse gases from shipping.
