Africa to Use Inexperienced Hydrogen to Produce Fertiliser – Watts Up With That?

Essay by Eric Worrall

The UN has been pushing poor, fossil gas wealthy African international locations to embrace intolerably costly inexperienced options to their meals manufacturing issues.

How Transformative Innovation Can Shift the Needle on Local weather Change

15 December 2022

UN Local weather Change Information, 15 December 2022 – On the UN Local weather Change Convention COP27 in Sharm el-Sheikh in November, authorities delegates and quite a lot of specialists highlighted essential revolutionary approaches to deal with local weather change notably within the areas of power, meals and buildings at International Innovation Hub dialogues organized by the UN Local weather Change secretariat.

…

Inexperienced hydrogen for the primary time within the focus as a significant answer to local weather change 

At COP27, individuals for the primary time closely centered on inexperienced hydrogen as a key element of the transformation to wash power, which is important to attain the central Paris Settlement objective of holding world common temperature rise to as shut as potential to 1.5 levels Celsius.

…

While representatives of the African international locations Mauritania and Namibia defined that their international locations have been eager to capitalize on the potential of inexperienced hydrogen and to develop industries whereas creating jobs, additionally they famous an additional key space wherein inexperienced hydrogen could be deployed: boosting meals manufacturing with the assistance of zero-carbon ammonia fertilizer produced with the assistance of hydrogen. Ammonia manufacturing may be very energy-intensive and presently causes round 1.8% of world carbon dioxide emissions.

“At this stage, exporting hydrogen is difficult by way of transport and effectivity. Ammonia appears to the be the one of many prepared options, there’s a market already for that,” stated Khoumbaly Lebhbid of Mauritania’s Ministry of Petroleum, Mines and Power.

Mauritania and Namibia don’t want experimental options, they want tried and examined options, which may clear up their meals shortages and poverty. And such options can be found.

Business ammonia manufacturing within the West requires huge portions of fossil gas. Mauritania has one of many largest pure fuel deposits in Africa. Namibia additionally has giant oil and fuel deposits. Each nations are struggling to draw funding to develop the assets – however the assets are there, ready to be exploited.

So why would the UN push one thing like inexperienced hydrogen, which has but to reveal value competitiveness in the true world?

I think, and that is solely a guess, that the UN would love Mauritania and Namibia to go away their fossil gas deposits within the floor. They usually could be getting some assist from individuals contained in the Mauritanian and Namibian governments.

If Mauritania and Namibia drilled just a few fuel wells, and used well-known, business processes to supply Ammonia, they might vastly enhance meals manufacturing nearly in a single day, in addition to producing substantial portions of a beneficial export product.

Dilute Ammonia could be utilized on to vegetation as fertiliser, with none additional processing.

Every time I wash out the pet room, I generally throw the waste dilute Ammonia ground cleaner on my citrus timber. The outcomes have been spectacular – in my subtropical again yard, my fruit timber placed on inches of development each time I apply the ammonia. The ammonia doesn’t appear to construct up within the soil, my guess is any ammonia which isn’t absorbed merely evaporates or washes away.

However Ammonia which evaporates from fields is a greenhouse fuel. And the manufacturing of Ammonia releases giant portions of CO2, each to compress the gasses to the large temperature and strain required, and from steam reforming fossil gas to supply hydrogen, one of many elements required for Ammonia synthesis.

N₂ + 3H₂ = 2NH₃ (Ammonia)

I don’t know why Khoumbaly Lebhbid of Mauritania’s Ministry of Petroleum, Mines and Power, whoever he’s, is talking in help of UN plans to divert his nation into an unproductive useless finish like inexperienced ammonia manufacturing.
