Emirates Flight Catering and Crop One Holdings announced plans this week for what would be the world’s largest vertical food farm, to be based in Dubai.

Vertical farms—indoor facilities in which crops are grown in hydroponic systems stacked on top of one another—are ideal for all kinds of situations. Old, abandoned urban factories make for nice vertical farms. But they might be best suited for environments like the United Arab Emirates, where arable land is rather limited but sunshine, which can be used for clean energy, is nearly limitless.
The green vegtation food facility will span 130,000 square feet, which makes it nearly twice as large as the previous (planned) champion, based in Newark, New Jersey, just outside New York City.USA.
Vertical farms have lots of distinct advantages. Being indoors, they aren’t subject to seasons and can produce food year-round. And being locked off from the outside world means that they typically use zero pesticides.
One way to counteract the large energy footprint of vertical farms is to set up a clean energy source. Crop One told CNN that it will be using a mix of power grid energy and solar; Dubai does not currently get very much of its energy from solar power but has announced ambitious plans to ramp up solar power in the next several years. Its target by 2050: is that75 percent of Dubai’s energy will come from solar power generation.
The Crop One facility will primarily grow greens, which do very well in systems like this and aims to harvest 6,000 pounds of greens every day. Those will be going, not surprisingly given its co-owners, to in-flight and airport lounge meals starting in December of 2019. Crop One has not announced plans to grow anything besides leafy greens at this stage, but more variety is certainly possible; squash, peppers, and some fruits (like strawberries) have proven able to handle vertical farming conditions.
