In a bold exploration of energy innovation, the U.S. Air Force’s Boneyard in Arizona—the final resting place for retired military aircraft—may hold a surprising key to addressing the burgeoning demand for electricity among data centers. As technological advancements compel data center operators to seek alternative energy sources, repurposed jet engines have emerged as a potential solution. This concept poses significant implications for small business owners, particularly those in tech and energy sectors.
Amid a backdrop of increasing energy consumption, operators of data centers in Texas have successfully implemented modified jet engines as power generators, each capable of producing 48 megawatts (MW). This approach exploits the vast pool of retired military aircraft at the Davis-Monthan Air Force Base, which houses around 4,000 planes, raising questions about the feasibility of harnessing their engines for electricity generation.
The theoretical capacity of these retired engines is staggering. Estimates suggest that converting the available jet engines could yield up to 40,000 MW of electricity—representing a potential 10% increase to Arizona’s current power-generation capacity. However, the opportunity comes with a set of challenges that small business owners should carefully consider.
Understanding the Electrical Potential
The core of this potential lies in the types of turbine engines housed at the Boneyard: turbojets, turbofans, turboshafts, and turboprops. Notably, turbofan engines emerge as the largest source of viable generating capacity, estimated at 32,000 MW. These engines serve as the basis for existing aeroderivative combustion engines, underscoring their compatibility for electricity generation. Manufacturers already produce refurbished models derived from aircraft engines, and their robust performance in utility applications is well-documented.
Chris Higginbotham, a principal contributor to the study, highlights that while this retrofitting process seems plausible, factory-produced models usually offer superior efficiency for electricity generation than those modified from retired engines.
Navigating Practical Implications
For small business owners, the applicability of this innovation extends beyond mere numbers. Companies venturing into energy production or those heavily reliant on data center services could find financial as well as operational benefits in utilizing such a renewable energy source. However, the logistics surrounding the recovery and renovation of these engines are complex. After sitting idle for years, the condition of the engines, the costs associated with conversion, and military requirements for retaining certain assets play significant roles in determining feasibility.
Moreover, whereas turboshafts from military helicopters could provide around 1,600 MW of capacity, the costs associated with modification and installation may surpass their generated electricity value. Each turboshaft has an average capacity just below 1.5 MW—less efficient compared to modern reciprocating engines commonly used for backup power.
Turboprop engines, like those from the iconic C-130 Hercules, represent another opportunity for generating electricity. Estimates suggest that these engines could offer about 7,300 MW collectively. For small businesses exploring backup power options, this could lead to a potential new avenue for energy sourcing.
Potential Hurdles
While the prospective benefits of utilizing these retired military engines are exciting, business owners should remain cognizant of the potential hurdles. There’s an inherent uncertainty regarding the practicality and cost-effectiveness of tapping these resources. Beyond initial investments, owners must account for ongoing maintenance costs and the realities of operational logistics, which may ultimately influence their bottom line.
As the energy landscape continues to evolve, the dream of harnessing jet engines for power generation at data centers is tantalizing yet fraught with complexity. Small business owners must weigh the potential for increased efficiency and cost reductions against the multifaceted challenges that come with implementing such innovative solutions.
The conversation surrounding this new energy frontier is only just beginning. Business leaders can stay informed by exploring developments in the field and considering how emerging technologies in power generation might be applicable to their operations.
