The race for the most innovative sustainable energy discovery in the automotive sector is in full swing! A Chinese company has just unveiled a toxic new fuel that will run in a combustion engine, but less polluting than fossil fuels. They promise it will be a great solution for the industry’s energy transition, potentially even displacing hydrogen, seen by many experts as the fuel of the future. Discover everything about this new toxic fuel that promises to be more sustainable and what is the company behind this innovative and bold launch.
A dangerous fuel as an option for the future
Guangzhou Automobile Group Co., better known as GAC, a renowned Chinese car manufacturer, is behind this innovative launch for the automotive market. It promises to meet the new needs of the automotive sector, following new regulations for companies — especially in Europe — seeking to reduce their carbon footprint. This major launch is a combustion engine powered by a slightly different fuel, even considered toxic: liquid ammonia.
GAC revealed this new launch at the company’s annual technology event. While not particularly groundbreaking, as ammonia was already used as a fuel in trucks and marine vehicles, the company still stands out with this new project as a pioneer in applying this type of fuel to regular passenger cars. This is something never seen before, and there’s some curiosity about how the company will implement this process.
This curiosity about the process stems from the fact that ammonia is considered toxic due to the high nitrogen in its formulation. The idea of using ammonia in passenger cars may sound potentially dangerous, but GAC guarantees that this fuel works well for internal combustion vehicles, safely, technologically, and, of course, more sustainable and affordable than other options.
Maybe it’s not so simple to implement ammonia in passenger cars…
GAC reported that, to maintain the proper functioning of the ammonia-fueled car, and to ensure that this process is as sustainable and safe as possible, it will operate as follows: the engine will have a sufficiently high cylinder pressure to prevent some of the excess nitrogen in the ammonia formula from escaping and causing problems.
Obviously, there’s no guarantee that we’ll see ammonia on the market anytime soon, or even that it will be an easy fuel to implement in passenger cars. In addition to the obvious safety risk, since ammonia is a toxic substance that can dissolve alkali metals and even lead to the death of humans and animals — in the case of prolonged exposure to ammonia in either gaseous or liquid form — it also has a very slow combustion, burning slowly, which can impact the car’s performance.
The positive side of this new fuel is that, according to its manufacturers, the combustion engine that runs on liquid ammonia emits 90% less carbon dioxide than a conventional combustion engine, generating an excellent result in the process of reducing the carbon footprint. We’re eager to see if these conditions will be sufficient for the implementation of ammonia and whether the company can overcome the challenges involved.
The uncertain future of ammonia as a fuel
While GAC’s project is bold and marks a new and important era for the automotive sector in its quest for more sustainable energy sources, the choice of liquid ammonia as a fuel remains uncertain and risky when it comes to implementation and use. At this point, what we have is a promise, which still requires further research before it can be realized. But we are eager to follow the energy transformations in the automotive sector and see what solutions, not only GAC but other companies, will come up with for a better future in automotive world.
