This GAC Group and Toyota-developed ammonia-combustion 2.0-litre four-cylinder engine produces 120kW of power. It also emits 90 per cent less carbon than an equivalent petrol engine.
Hydrogen released from splitting ammonia through electrolysis via the Haber-Bosch process is cheaper easier and safer to transport than hydrogen fuel cells for vehicles.
The main input is natural gas. All Hydrogen fuel models for car transportation source the hydrogen from natgas, ultimately. The japanese have been trying out several methods, like this one, for the engine part of it. The back-end supply chain infrastructure is being set up in major natgas producing countries, Russia notably.

Yes, ammonia is produced from natural gas. It's still going to compete with ammonia for fertilizer. There have already been recent fertilizer shortages.
the volume of ammonia production is set to the demand for fertilizer. if more is needed for fuel, the production can be expanded to match that demand. that said the video itself says clearly that ammonia is a poor fuel choice. This project was more about solving a few issues with ammonia as a fuel because it has some interest for boutique applications. For personal automobiles, a more direct hydrogen delivery system is inevitable. Ammonia is basically just a way to deliver hydrogen fuel.
Cars in the near future will be like plug-in hybrids are today. Smaller electric engines designed to be used for most short haul trips, which can be charged directly, but also paired with an ICE engine running some kind of hydrogen fuel that can also charge the battery. The primary issue with EV cars is that it's impossible to make enough batteries for every vehicle in the world and the charging times. for long haul ICE is far superior and it's just a matter of swapping out the petrol fuel for something else that doesn't create air pollution. hydrogen is the answer to that and the infrastructure work to ensure production volumes is already beginning. The remaining question is exactly how it will be stored and delivered to cars. Experiments like the one in your link are about answering that question. Essentially they are all trying to figure out ways to boost efficiency of hydrogen - fuel cells are already there for cars but many transport vehicles could potentially benefit from different fuels. It's the same as today where there are many different formulations of petrol fuel and engines that make sense for different things such as boats, planes, machines, etc.
Climate change is of course total bullshit but air pollution is not. Many of the world's cities are in valleys and invection layer effects trap air pollution within them - cars being a major contributor to that. The advantage of non-particulate fuels is clear in these environments despite the efficiency tradeoff from petrol. The pollution generated from producing the hydrogen is not an issue because it can be done far offsite, often very remotely, where it can be dispersed without impacting the human population.
