Taking a deep breath, Han Zizhen asked: "Academician Xu, how much does this carbon dioxide adsorption and capture device cost approximately?"

Xu Chuan shook his head and said: "I really don't know much about this. But among the porous liquefied DAC carbon dioxide traps, the most expensive one is the material that adsorbs carbon dioxide inside. The other materials shouldn't be that expensive."

"As for the carbon dioxide adsorption material, that is, ion exchange membrane isophorone diamine, according to the current cost, it is probably close to 300 per kilogram."

"One kilogram of isophorone diamine can cover an adsorption area of ​​about two square meters. Each square meter can treat about one hundred cubic meters of air in one hour."

"However, isophorone diamine is not disposable. It can recycle itself. Simply put, it can be used for a long time after being put in once. According to the current experimental data, it can probably run for almost ten years."

"The specific cost price will probably have to be calculated later."

Han Zizhen nodded and silently calculated in her mind.

Three hundred yuan per kilogram can be used to pave two square meters. Based on the area of ​​a commercial building of 20,000 square meters, even if it is just to modify the exterior wall, the carbon dioxide absorption material alone will cost at least 300,000 yuan.

It may not sound like much, but it is just a ‘part’ in this set of equipment, and only one floor of a building has been renovated.

If there are 500 buildings in Jinling City that are more than 100 meters tall, that is, more than 30 floors, and each building has one floor renovated, then the adsorption materials alone will cost at least 150 million.

Although the one in front of you is said to be the most expensive part of the entire equipment, other parts, especially such high-tech equipment, may not be that cheap.

Overall, if this project is carried out, it is roughly estimated to start at tens of billions.

This number is too big for him to make the decision alone.

Moreover, no benefits will be seen from this project in a short period of time. Strictly speaking, this is a public welfare project for people's livelihood.

Although Han Zizhen believed what the person in front of her said, carbon dioxide is a resource and can also be converted into starch, gasoline and other materials.

But overall, the main purpose of this project is to change the atmospheric environment of Jinling City and reduce the urban temperature.

Whether it's worth it or not, I'm afraid there's some quarrel with the city government this time.

Of course, although the investment is huge, if it can really be done, Jinling will undoubtedly become the most livable city in China, and it can even be said that there is no other city.

Because a suitable living climate is fatal to the attraction of ordinary people.

Who doesn't want to think that in summer, the temperature outside is still only 25 or 26 degrees Celsius?

This is to create a super city that is most suitable for human habitation.

Suddenly, a thought flashed through Director Han's mind.
