Toelichting (Engels) This study is an exploration and reality check of a novel concept. It investigates to which extent protein production by means of single cell protein (SCP) production using hydrogen gas (H 2 ), oxygen gas (O 2 ), carbon dioxide (CO 2 ) and ammonia (NH 3 ) is economically feasible. These substances are all available on the farm. The process uses off peak (redundant) green electricity which is converted by means of electrolysis of water to hydrogen gas (H 2 ) and oxygen gas (O 2 ). The nitrogen source can be either ammonia (NH 4 ) from fertilizers or recovered ammonia from manure stripping processes. In this way the ammonium is cleared from any other substances in the manure. The carbon source, carbon dioxide (CO 2 ), can be concentrated from fermentation gases (e.g. biogas) or from exhausted industrial air emissions. Hydrogen, oxygen, ammonia and carbon dioxide can be used as inorganic substrates for a mixed microbial community of chemolithoautotrophic bacteria, i.e. hydrog en-oxidizing bacteria. These bacteria are capable of producing protein-rich biomass at re latively high yields, which can be used as feed on the farm. Indeed, the technological co ncept offers the farmer the opportunity of (partial) self-supply of feed.

To support researchers to publish their research Open Access, deals have been negotiated with various publishers. Depending on the deal, a discount is provided for the author on the Article Processing Charges that need to be paid by the author to publish an article Open Access. A discount of 100% means that (after approval) the author does not have to pay Article Processing Charges.

For the approval of an Open Access deal for an article, the corresponding author of this article must be affiliated with Wageningen University & Research.
