Mapping Territorial Readiness for Green Hydrogen Deployment in Colombia: A GIS-Based Multicriteria Framework
This study develops a GIS-based multicriteria framework weighted by expert consultation to map Colombia's territorial readiness for green hydrogen deployment, revealing that optimal locations depend on a complex integration of economic, infrastructural, and institutional factors rather than renewable resource availability alone.

The Big Idea: It's Not Just About the Sun and Wind
Imagine you want to open a new, high-tech bakery that makes "Green Bread" (which represents Green Hydrogen). To make this bread, you need two main things:
- Ingredients: Lots of sunshine and wind to power your ovens (renewable energy).
- A Good Location: A place with a road for trucks, a water supply for the dough, a nearby market to sell the bread, and a safe neighborhood where the police and local government are helpful.
For a long time, people thought, "Let's just build the bakery wherever the sun shines the brightest." But this paper argues that's a bad idea. If you build your bakery in the middle of a desert with no roads, no water, and no security, you can't actually make or sell the bread, no matter how much sun you have.
The Goal: This study created a "Smart Map" for Colombia to find the best places to build these green hydrogen projects. It didn't just look at the weather; it looked at the whole neighborhood.
How They Made the Map (The Recipe)
The researchers used a computer system (GIS) to layer different pieces of information, like stacking transparent sheets on top of each other. They looked at 15 different ingredients to decide if a spot was "ready" for a project.
They grouped these ingredients into five categories:
- The Power Source: Is there enough sun or wind? (The ingredients).
- The Cost & Tech: Is the equipment ready to use, and will the bread be cheap enough to sell? (The business plan).
- The Roads & Tools: Are there power lines, roads, ports, and universities nearby to help? (The infrastructure).
- The Water & Nature: Is there enough fresh water without hurting protected forests or Indigenous lands? (The environment).
- The Rules & Leaders: Does the government have good laws and incentives to help? (The rules).
The "Taste Test" (Expert Weights):
To decide which ingredient was most important, they asked 16 experts to vote. They used a method called the "Best-Worst Method." Imagine asking a chef, "What is the most important thing for this bread?" (Answer: The cost of flour) and "What is the least important?" (Answer: The color of the bag).
- Result: The experts said the cost of production was the most important factor, followed closely by the amount of sun/wind and how close you are to existing roads and power lines.
What They Found (The Results)
When they combined all these layers, they got a colorful map showing "Readiness Zones."
The Surprise:
The places with the absolute most sun and wind were not always the top-ranked spots.
- The Winner: Valle del Cauca took first place.
- The Runners-Up: Cundinamarca, Antioquia, Santander, and Cesar.
Why?
Think of it like this: A place might have a huge, empty field with perfect sun (high renewable potential), but if it's 50 miles from a road, has no water, and is in a conflict zone, it's a bad spot for a bakery.
Valle del Cauca won because it had a balanced mix: good sun, plus good roads, plus water, plus a supportive local government. It was the most "ready" place to actually start building.
The "Polycentric" Pattern:
The map showed that readiness isn't just in one corner of the country. It's scattered in different hubs (like a city with several busy neighborhoods rather than just one downtown). This means Colombia has many different places where green hydrogen could work, depending on what kind of project you want to build.
The "Safety Check" (Conflict and Governance)
After making the main map, the researchers did one more step. They looked at two other maps:
- The Conflict Map: Where are there safety issues or social tensions?
- The Governance Map: Where is the local government strong and organized?
They didn't use these to change the "score" of the land, but to add a warning label.
- Analogy: Imagine you found a perfect spot for your bakery. But then you check the news and see that the neighborhood is currently in a riot. The paper says, "This spot is technically perfect for the oven, but you might need to wait or fix the neighborhood first before you start building."
The Main Takeaway
This paper is a tool for planners. It tells them:
- Don't just look at the weather. You need to look at the whole picture (roads, water, laws, safety).
- Not all sunny spots are equal. A place with "medium" sun but "excellent" roads and water is often a better place to start than a place with "perfect" sun but no roads.
- It's a starting point. This map doesn't say "Build here tomorrow." It says, "These are the best neighborhoods to start your homework and planning."
In short, the paper helps Colombia move from asking "Where is the sun?" to asking "Where can we actually build a successful green hydrogen business?"
