The Data Center Boom: A Critical Need for Clean Backup Power
From cloud computing to AI-driven applications, the demand for data processing and storage across the U.S. is skyrocketing, and with no end in sight. In 2023, the U.S. data center construction market was valued at approximately $24.59 billion and is projected to reach $47.72 billion by 2029, reflecting an impression annual growth rate of 11.69%. This rapid growth is further underscored by the fact that nearly 6.5 gigawatts (GW) of data center power supply is currently under construction, with 72% of this capacity already preleased.
In other words, as technology continues to advance, data centers will require greater energy capacity to operate without disruption. But to prevent the country’s computing systems from going dark, reliable backup power is a necessity.
Diesel generators have long been the go-to solution for emergency power in data centers, ensuring uninterrupted operation during outages. As sustainability is top of mind today, concerns over diesel emissions and their environmental impact are intensifying. Striking a balance between reliability and sustainability is now more important than ever.
If witnessing this unprecedented growth has taught us anything, it’s that we need to continuously explore options to help data centers reduce their environmental footprint while maintaining operational resilience.
When the power goes out
During a power outage, even a short one, the results can be catastrophic for data centers. Downtime means lost revenue, disrupted services and potentially damaged reputations. To prevent disorder, data centers depend on backup power systems to keep operations running smoothly during an outage.
Diesel generators, while reliable, come with their own set of environmental challenges. These engines produce significant emissions, including nitrogen oxides (NOx), particulate matter (PM) and carbon monoxide (CO), all of which contribute to air pollution and climate change. With strict emissions regulations, data centers are sometimes forced to abide by standards and therefore need new solutions to reduce their carbon footprint.
In addition to regulatory challenges, there is increasing pressure from stakeholders, ranging from investors to customers, to adopt more sustainable business practices.
Practical (and immediate) ways to reduce emissions: DPFs and SCR systems
In response to these valid concerns, many data centers are turning to innovative solutions like diesel particulate filters (DPFs) and selective catalytic reduction (SCR) systems to reduce the emissions from their backup diesel 
generators. These technologies enable data centers to continue using diesel backup systems while minimizing their environmental impact.
Diesel Particulate Filters (DPFs) work by trapping and removing harmful particulate matter from the exhaust gases of diesel engines. DPFs are essential in reducing black soot, which can cause serious health issues and contribute to air pollution.
Selective Catalytic Reduction (SCR) systems, on the other hand, target nitrogen oxide (NOx) emissions. NOx is a major contributor to smog and acid rain, and SCR systems help reduce its concentration by injecting a reducing agent (usually urea) into the exhaust stream. This process converts harmful NOx gases into nitrogen and water vapor, significantly lowering the environmental footprint of diesel backup generators. When combined with SCRs, DPFs create a comprehensive emissions control system that meets the strictest environmental regulations.
Together, DPFs and SCR systems represent a realistic and immediate approach to reducing black particulate matter and maintaining the reliability of diesel-powered backup systems. These technologies ensure data centers can stay compliant with evolving emissions standards while continuing to deliver the uninterrupted power that is critical to their operations. When combined with SCRs, DPFs create a comprehensive emissions control system that meets the strictest environmental regulations.
Rypos takes emissions control a step further
DPFs are a proven solution for minimizing the environmental impact of diesel generators at data centers, and Rypos takes emissions control a step further with its advanced technology.
Rypos’ active, self-cleaning filters are specifically designed to regenerate independent of exhaust temperature. Unlike passive filters, they do not require excessive run times for cleaning and eliminate the need for facility personnel to track the number of cold starts between service intervals. With the ability to remove up to 95% of harmful particulate matter (PM) and meet the California Air Resources Board (CARB) requirement of an 85% reduction, Rypos active DPFs offer an effective emissions strategy.
Beyond particulate matter, these filters also help minimize other harmful pollutants. Rypos active DPFs trap and eliminate PM while converting carbon monoxide and hydrocarbons into carbon dioxide and water. Additionally, when configured with selective catalytic reduction (SCR) technology, these systems can reduce nitrogen oxide (NOx) emissions, helping data centers achieve both reliability and sustainability in their backup power solutions.
The future of sustainable data centers
As the data center industry continues to expand, sustainability will remain a top priority. Governments and regulatory bodies are tightening emissions standards, and corporations are increasingly committing to net-zero and carbon neutrality goals.
Investing in clean backup power solutions is not just about regulatory compliance, it’s about corporate responsibility, environmental stewardship and future-proofing mission-critical operations.
