// CO₂ in the smart indoor agriculture

CO₂ injections for plant growth

CO₂ injection is a very well-known farming technique, it helps increase the growth of the crops, by fully maximising their photosynthesis potential. The importance of CO₂ for plants resembles the importance of food for humans – they grow by actually ‘eating it’.

By using CO₂ enrichment, it is possible to boost plant growth by 20 to 30%, depending on the type of crops.

// Where to get CO₂

Sourcing CO₂ for injections

Generally, CO₂ prices are quite high due to the need of transportation, liquefaction. With our on-site capturing technology pulling CO₂ directly from the open air, there is no need for such expenses.

Our target price is one of the lowest prices on any CO₂ of DAC origin – €150 per ton of CO₂.

Environmental benefits

Both retail and ecommerce are heading towards “carbon labeling” – special markings with an indication of the carbon footprint of the growing.

The carbon footprint of greenhouse growth is mainly linked to traditional fossil-based heating. Because of the regulatory pressure to reduce carbon emissions (EU GREEN DEAL, US Climate Strategy) and unstable fuel prices, growers will soon be forced to look for alternatives to provide energy for their greenhouses. And this will drive them to source CO₂ from an external supply.

We offer a stable supply of clean CO₂ from the air locally, thus eliminating the traditional CO₂ supply cost chain, and reducing the carbon footprint of the outcome product.

How does it work?

Signing a contract with Carbominer

The grower leaves a request in the form, we connect, negotiate the billing terms, and sign an agreement

Delivery and installation of the DAC module

We deliver the capturing module to the grower's premises and install it for free, connecting to the target greenhouse

Increasing crop yield with fossil-free CO₂

The capturing module pulls CO₂ from the air and sends it to the greenhouse to promote the plant growth

The optimal CO₂ injection

Plants consume CO₂ only up to a certain level that is beneficial to their growth. If the carbon dioxide level is too high, the crops will start to deteriorate.

We have conducted several customer discoveries, which have shown that the optimal amount of CO₂ in greenhouses depends on the crop type. The average indicators of CO₂ levels range from 700 ppm to 1500 ppm.


Frequently Asked Questions

What is the cost of Carbominer CO2?

The cost of the CO₂ is one of our main advantages. Since our process is energy efficient, we are going to offer CO₂ at an affordable price, lower than any other fossil-free CO₂ from the open air.

There is no generic price of CO₂, as it depends on the cost of the electricity in the target region. If you'd like to receive a calculation for your premises, please contact us.

With our price, greenhouse operators and vertical farmers can cut their expenses and raise their margins significantly. It is possible not only to promote plant growth by 20-30%, depending on the type of crops but also make essential cost-savings on reduced carbon taxation.

What are the climate benefits of Carbominer tech?

Another important aspect of our technology is that it is climate-friendly. With low- or zero-carbon energy sources, it can easily reach zero-emissions status, which is essential for countries with such regulations.
With our clean CO₂ from the open air, greenhouse growers can reduce their current emissions and the carbon footprint of the final products. As the CO₂ is captured locally there is no need for a traditional CO₂ supply chain – liquefaction, transportation, and gasification, all of which have their energy needs and carbon footprint.

How do growers benefit from Carbominer's solution?

We are open to assisting growers and vertical farmers in the calculation of their benefits – both regarding profit margins and emissions reduction. If you would like to get a calculation for your greenhouse or vertical farm, please, submit the form below.
