From Pollution to Profit: How Power Plants Can Monetize Recovered CO₂
Power plant operations are among the largest contributors to global carbon emissions. Fueled by coal, natural gas, and oil, these power plants release significant amounts of CO₂ into the atmosphere with every megawatt generated. According to the International Energy Agency (IEA), electricity production accounts for nearly 40% of global CO₂ emissions, placing power plants squarely at the center of climate change challenges.
What if these emissions could become a valuable asset instead of a liability? This is where CO₂ recovery comes in – a process designed not only to cut emissions but also to unlock a new source of revenue. Rather than venting carbon into the atmosphere, a power plant can capture it and supply industries that depend on high-purity CO₂. Manufacturers like Hypro specialize in advanced CO₂ recovery systems that help power plants transform their emissions into a profitable, high-demand commodity.
With the rising need for Carbon Capture and Utilization (CCU), power plants now have the chance to transform from major emitters into crucial suppliers for a growing carbon-based economy – turning pollution into profit.
Why Should Power Plants Consider CO₂ Recovery?
Revenue Generation from CO₂ Sales
Historically, power plants have treated CO₂ as an unavoidable byproduct. Today, however, that same CO₂ is in high demand. From food and beverages to oil recovery and chemical production, industries worldwide rely on steady supplies of carbon dioxide.
By adopting CO₂ recovery solutions offered by Hypro, a power plant can capture emissions and sell the recovered gas to various sectors, generating fresh income from what was once waste.
Industries that purchase CO₂ include:
- Food and beverage producers for carbonation and packaging.
- Oil fields using CO₂ for Enhanced Oil Recovery (EOR).
- Chemical and fertilizer plants in processes like ammonia and urea production.
- Greenhouses to accelerate plant growth.
For any power plant, this shift turns carbon emissions into a profitable product, supporting both business growth and sustainability goals.
Diversification of Business Model
A traditional power plant relies almost entirely on electricity sales. But with fluctuating tariffs, evolving regulations, and the rise of renewable energy, this single-stream model is no longer enough to ensure long-term stability. This is where Hypro steps in – enabling power plants to diversify their revenue by adding a valuable alternative: CO₂ recovery. Through advanced
technology, Hypro helps capture emissions directly from power plants and convert them into food-grade CO₂ with 99.998% v/v purity, opening doors to lucrative markets like food, beverages, and industrial applications.
By tapping into this second revenue stream, power plants can reduce their reliance on unpredictable power markets while strengthening their financial resilience. The result is a forward-thinking energy model that balances electricity generation with profitable carbon recovery, all while actively cutting down on emissions.
Transforming Industrial Emissions with Hypro’s CO₂ Capture Technology
Flue gas from high-temperature industrial processes carries significant CO₂ emissions. Instead of releasing this into the atmosphere, it is directed to a CO₂ recovery plant where impurities like particulate matter, NO₂, and SO₂ are removed, and CO₂ is separated from nitrogen and oxygen.
Hypro’s advanced technology captures CO₂ at the source and produces food-grade Liquid CO₂ with over 99.99% v/v purity. The process uses optimized amines for efficient CO₂ absorption and low-energy desorption, minimizing heat consumption and reducing amine degradation. To ensure longevity, stainless steel columns are used to withstand corrosion from hot amine solutions. Additionally, industries can utilize available waste heat or excess steam to power the system, enhancing overall efficiency.
The recovered CO₂ is liquefied and stored in vacuum-insulated tanks, ready for applications such as beverage carbonation, chemical manufacturing, and e-Methanol production – transforming emissions into valuable products.

Coal-Fired Power Plants: Giants of Energy, Titans of Emissions
Coal-fired power plants have powered economies for over a century, but at a steep environmental cost. These facilities burn coal to generate electricity, releasing enormous amounts of CO₂ into the atmosphere. According to the International Energy Agency (IEA), coal-fired power generation alone accounts for nearly 30% of global CO₂ emissions. On average, a coal-fired power plant emits 2.2–2.5 pounds of CO₂ per kWh, making them one of the biggest contributors to industrial carbon emissions.
Yet, coal-fired power plants don’t have to be just emitters; they can also be part of the solution. With carbon capture technologies, CO₂ from power plants can be repurposed for enhanced oil recovery (EOR) or converted into synthetic fuels and chemicals, turning pollution into profit. Some research suggests that captured CO₂ can even be mineralized into solid carbonates for construction materials, creating new revenue streams while reducing emissions. Although these solutions require significant investment, they offer a glimpse of a future where even the most carbon-intensive power sources can contribute to sustainability.
Natural Gas Power Plants: The Lesser Evil or a Hidden Opportunity?
Natural gas power plants are often touted as the cleaner alternative to coal, and for good reason. They produce about 0.9–1.2 pounds of CO₂ per kWh, nearly half the emissions of a coal-fired power plant. However, this doesn’t make them entirely green – especially when factoring in methane leaks from natural gas extraction and transportation, which can have an even greater warming effect than CO₂.
Interestingly, the CO₂ emitted from natural gas power plants isn’t just a byproduct – it’s a resource. Many industries rely on purified CO₂ for food and beverage carbonation, water treatment, and chemical manufacturing. Moreover, studies indicate that integrating direct air capture (DAC) with natural gas power plants can significantly reduce net emissions while generating high-purity CO₂ for industrial applications. By investing in carbon capture and utilization (CCU), natural gas power plants can transition from being mere polluters to key players in a circular carbon economy, where emissions are repurposed rather than wasted.
Oil & Gas Industry: Refining the Future of Carbon Utilization
Refineries and petrochemical plants are the backbone of modern industry, supplying fuels, plastics, and countless synthetic materials. However, this comes at a high environmental cost – oil refineries and petrochemical facilities collectively emit 2–3 tons of CO₂ per ton of refined product. The high energy demand and chemical processes involved in refining crude oil into usable products make this sector a significant carbon contributor.
Surprisingly, this industry has also pioneered CO₂ utilization. Enhanced oil recovery (EOR), a process where CO₂ is injected into oil wells to boost extraction rates, has been in use for decades. Additionally, refineries are exploring CO₂ conversion into synthetic fuels, polycarbonate plastics, and industrial solvents. According to a McKinsey & Company report, advanced carbon capture technologies could create a multi-billion-dollar market for CO₂ – derived fuels and chemicals. By integrating more CCU solutions, the oil and gas sector can turn emissions into economic assets, mitigating its environmental footprint while maintaining profitability.
Chemical & Fertilizer Plants: Turning CO₂ Emissions into Industrial Gold
The chemical and fertilizer industries, particularly ammonia, hydrogen, and methanol production, are another major source of CO₂ emissions. Ammonia plants, essential for fertilizer production, release around 1.8 tons of CO₂ per ton of ammonia produced, while global hydrogen production contributes nearly 830 million metric tons of CO₂ annually. The culprit? Steam methane reforming (SMR), a process that extracts hydrogen from natural gas while releasing CO₂ as a byproduct.
Yet, these industries also present some of the best opportunities for CO₂ reuse. Captured CO₂ is a key ingredient in urea production, an essential fertilizer component. Methanol plants are increasingly adopting carbon recycling methods, using CO₂ as a feedstock for producing chemicals and fuels. The Carbon XPRIZE competition has showcased breakthrough technologies that transform CO₂ into high-value materials such as carbon fiber and bio-based plastics, proving that emissions can be converted into profitable commodities. With advances in CCU, the sector has the potential to transform waste CO₂ into valuable products, helping to close the carbon loop in industrial manufacturing.
The Power Plant and Industrial Shift to a Circular Carbon Economy
Many of these industries tells a two-sided story – while they are among the largest CO₂ emitters, they are also at the forefront of carbon utilization. From coal-fired power plants to cement kilns, oil refineries to fertilizer plants, the shift toward carbon circularity is no longer just a vision; it is a necessity. As studies continue to highlight the economic potential of CO₂ conversion, businesses that invest in pollution-to-profit strategies will not only reduce their carbon footprint but also unlock new revenue streams in the evolving green economy.
