How Cycling Maximizes the Fuel Efficiency of SOFC

“The best part of my role is when I get to witness a customer’s excitement as they see for themselves what our aircraft are capable of, especially when they discover the flexibility, ease of use, and capability to easily integrate other technologies,” says Grace Burgess, Training Manager of Flight Operations at Edge Autonomy. “It’s really gratifying when a customer tells me, ‘That is exactly what we must have to fulfill our operational needs.”

And the demand for flight demonstrations and training is growing. Grace and the Edge Autonomy flight operations team have travelled the globe to showcase our uncrewed aerial capabilities for customers and partners, training new pilots and providing education for operations teams.

Not only does Edge Autonomy currently have more than 300,000 square feet of production and manufacturing space, but we also have multiple committed airspace locations devoted to training, demonstrations, and quality control.

“I enjoy traveling to meet our customers and partners wherever the need for our UAS technology lies,” says Grace. “And as a company we are also in an exciting time of expansion, which means that our dedicated flight operations facilities in the U.S. and overseas are growing to be even better equipped to accommodate the needs of our clients.”

A Strong Foundation in Aviation

Rapid growth and an ever-increasing demand for flexible and adaptive UAS technology makes strong organizational skills and a deep understanding of the industry a must. The daughter of a pilot who served in the U.S. Army while she was growing up, Grace found an early mentor in her father, who also worked in the drone and aviation industry. In addition to instilling her with a love of travel and a keen interest in technology, Grace’s military upbringing gave her a growth mindset and made her highly adaptable.

“This is a very fast-paced, ever-evolving industry and a lot is going on all the time,” says Grace. “Being resilient and adaptable to those changes is key to meeting the real-world needs our customers face, all while being open to learning about how our aircraft fit into current and future mission needs. It’s important not to be afraid to ask, ‘How can I learn more? How can I make this work?’ These questions not only lead to new technological innovations, but they keep me growing in my career.”

From flight safety and standardization to developing instructional curriculum and deploying as an operator, working in multiple disciplines within the UAS training arena gave Grace a solid foundation in aviation. Yet she believes her most intensive season of personal and professional growth began when she joined the Edge Autonomy team.

I’ve had opportunities at Edge Autonomy to complete trainings on new equipment and new technologies that I wouldn’t have been able to pursue elsewhere,” she explains. “My mentors within the company have given me so much opportunity for growth, as well as countless chances to move into leadership roles. I feel very blessed to have senior leadership that believes in my capabilities to step into more. More visibility and more responsibility.”

The Future of UAS: Maintaining the Human Factor in the Face of Automation

With all the buzz surrounding Artificial Intelligence and the swift changes taking place not only in aviation but in the broader technology culture at large, Grace believes it is critical not to lose sight of the human operators behind the technology.

“You have to understand people’s perspectives and the very personal ‘whys’ behind the needs our customers face,” says Grace. “We must remember that a human being ultimately operates a UAS. Our goal at Edge Autonomy, no matter what exciting technology advancements we implement, is to make a product that is as user-friendly and operable as possible.

“I’m really looking forward to up-and-coming capabilities that will give the operator even greater agility on the ground. How the operator controls the aircraft is going to change, I think, so it’s an exciting time to be working in this dynamic field.”

When comparing offgrid power technologies, key factors to consider are durability in different environments and maintenance needs. And one thing that will make a huge impact on the long-term cost of a power product is how much fuel it needs.

Some internal combustion engine generators, especially those unable to cycle on and off, can run just 8 hours on 20 pounds of propane. That can mean 3 site visits in one 24-hour period. This is fine if the generator is in an easy-to-reach location with good weather conditions, and if maintainers are available to make frequent refueling trips.

However, maintainers sometimes have to venture out in treacherous weather — from hurricanes and snowstorms to wildfires and ice storms — to keep power running. And some sites are so remote that refueling can only be done with a helicopter, ATV or other special transport, and only during certain months of the year. When site visits are costly or dangerous, finding a power source that’s highly fuel-efficient is vital.

At Adaptive Energy, our customers rely on our solid oxide fuel cells (SOFC) for reliable, low-maintenance and highly efficient power. Unlike all other low-watt offgrid power technology, our Performer Series SOFC are engineered to cycle on when voltage dips below a set threshold and back off when the battery is charged. Fuel is used only when the system is charging the battery, which is what makes our products so fuel-efficient.

And when it comes to measuring the cost of fuel, projected runtime is an important consideration because it dictates fuel usage. For example, if the SOFC cycles on to supplement a solar array only during times of darkness or cloud cover, it uses less fuel than a product that continuously runs like a generator.

In fact, 20 pounds of propane can provide 80 hours of runtime for a Performer Series SOFC. That’s days of power, compared to the hours available from a generator. This window also offers plenty of time to schedule a refueling visit when the conditions are safe. That’s why, especially for remote sites, fuel efficiency is crucial.
