As mentioned in chapter I, synthetic ammonia (NH3) has become the principal source of all nitrogen fertilizers, particularly since 1945. At present, over 95% of all commercial fertilizer nitrogen is supplied by or derived from synthetic NH3; only minor percentages are supplied by natural sodium nitrate, byproduct NH3 from coke-oven gas (usually ...

Inhibition of biohydrogen production by ammonia
Water Research, 2006Ammonia inhibition of biohydrogen production was investigated in batch and continuous flow reactors with glucose as a substrate. In batch tests, biohydrogen production rate was highly dependent on pH and ammonia (defined as the sum of NH3 of NH4+ species) concentrations above 2 g N/L.

Small-scale ammonia production: a superstructure approach
Ammonia is an important chemical for the energy transition as it can serve as a hydrogen carrier. Small-scale ammonia can be produced from decentralized or waste resources thereby integrating and expanding its use by delivering the product directly to the site of consumption.MartÃnez, Alonso +4 more

Renal production and excretion of ammonia
The American Journal of Medicine, 1964Abstract The secretion of ammonia, once thought to be limited to distal tubules and collecting ducts, has been shown to occur throughout the length of the nephron of the rat. As much as half or more of the ammonia excreted in the urine may be added to tubular fluid in the proximal segment.

Hydrogen Production through Ammonia Electrolysis
ECS Meeting AbstractsHydrogen, pivotal for a global carbon-neutral energy framework, faces hurdles in storage and transport, leading to the consideration of ammonia as a viable hydrogen carrier. Compared to hydrogen, ammonia can be liquefied at higher temperatures, and is safer in handling.
