How Ships Could Produce an Unlimited Amount of Their Own Fuel

Một con tàu có thể tự sản xuất ra nhiên liệu để vận hành như thế nào?

Scientists have taken a major step by improving a process for turning seawater into hydrocarbons. The barebones of the technology has existed since a landmark 2014 paper, but scientists have worked since then to make the process energy-efficient and affordable enough to use at scale in the field. This work could be a step toward that threshold.

The idea of seawater fuel is very simple. Ships can collect seawater to catalyze into fuel, and they already have pumps on board to return the waste water. If ships are self-sufficient with the ability to produce a virtually unlimited amount of their own fuel, they’re not just environmentally sound—they’re free to stay at sea for much longer times, especially during some kind of unforeseen emergency.

The reaction at play here is called reverse water gas shift, and it’s used in this context to turn carbon dioxide separated from regular seawater into carbon monoxide that can be synthesized into hydrocarbons. To do that, scientists use a reactive catalyst made of molybdenum carbide, a compound of extremely high-melting molybdenum and carbon.

In this case, the molybdenum carbide is interspersed with potassium and gamma alumina. Gamma alumina, like its siblings alpha and beta alumina, is another word for a form of aluminum oxide that’s effective as a catalytic support. Both potassium and gamma alumina help ensure the molybdenum carbide can put its most available, reactive, and energy-efficient foot forward in the reaction to turn carbon dioxide into carbon monoxide.

Futurity reports this research is set apart by its use of plentiful and low-cost components instead of the typically precious ingredients in previous iterations:

“The potassium-modified molybdenum carbide catalyst is synthesized from low-cost components and did not show any signs of deactivation during continuous operation of the 10-day pilot-scale study. That’s why this demonstration of the molybdenum carbide catalyst is important.”

The modifying ingredients are already widely available for other industrial uses, meaning they’re easy to buy rather than synthesize or produce.

 “Together, experiments across the molecular, laboratory and pilot scales demonstrate that K-Mo2C/γ-Al2O3 is an economically-viable RWGS catalyst with promising future applications in the US Naval Research Laboratory’s seawater-to-fuel process, downstream methanol synthesis and FT,” the study concludes.

If this step is a kind of feasibility study for the production of the catalyst itself, the next step is to examine how that combined catalyst really works, including in the real environment inside a ship. That means testing with impure water and gas and in environments where conditions can’t be as secured as they are in a lab. But this is a very promising development, and the researchers seem excited for what’s next.
