How Supercapacitors Can Shape Sustainable Data Centers

Over the past 48 years, LaFace and McGovern has become one of the most recognizable names in the lighting-controls sector and is now looking to do the same for power solutions. 

LaFace and McGovern made its first big step by partnering with Emtel Energy USA to bring its Electrostatic Long-Duration Energy Storage (ELDES) technology stateside as a solution pointed at data centers and their increased need for power and managing it efficiently. 

Central to this innovation is the introduction of supercapacitors as opposed to conventional batteries, promising a host of benefits from safety to efficiency. 

“It redefines what’s possible in sustainable power management,” said Steve Whittingham, VP of Power Solutions at LaFace and McGovern. “Unlike conventional lithium solutions, our solid-state innovation delivers reliable performance without environmental compromise—advancing the clean energy revolution while preserving our planet’s resources.” 

The Supercapacitor Advantage

At the heart of Emtel’s offering is the supercapacitor—a solid-state, electrostatic energy storage solution. Unlike lithium-ion batteries, which rely on chemical reactions and inherently generate heat, Whittingham said supercapacitors store energy electrostatically.  

“This translates to less risk of overheating and fire, addressing critical safety concerns especially in high-stakes environments like data centers,” he said. “By eliminating heat production, these supercapacitors can reduce operating expenses through decreased cooling costs.”  

Supercapacitors not only charge and discharge more rapidly than their battery counterparts, he explained, but they can also do so multiple times a day—up to four cycles—without voiding warranties.  

“This rapid cycling capability ensures consistent energy supply, critical for data centers that demand constant power availability,” Whittingham said. “Moreover, these units can simultaneously charge and discharge, further optimizing energy management.”  

Pioneering Grid Efficiency and Environmental/Economic Impact

As the energy grid becomes ever more strained, especially during peak demand periods, Whittingham said Emtel’s technology offers a viable solution. He went on to explain that, traditionally, solar and wind farms directly captured energy into a grid, failing to store it for peak times when demand spikes. Emtel's supercapacitors can change that dynamic, holding renewable energy and deploying it when needed most, thereby easing grid demand and improving resilience. 

Beyond economic savings, Emtel's technology represents a significant environmental win. Whittingham said the components are recyclable and biodegradable, crafted from synthetic graphene—made from recycled materials—eschewing the need for rare earth mining. With a round-trip efficiency exceeding 99% and a lifespan significantly surpassing traditional batteries, Whittingham pointed out that Emtel is setting new standards for sustainable energy solutions.  

The Path Ahead

Whittingham is excited to be headquartered in the Pittsburgh region as it sits central to energy production coming from multiple sources. 

"We have a geographical advantage to produce cost-effective power,” said Whittingham. “Integrating Emtel’s technology into this ecosystem creates a harmonious synergy between producing and distributing energy efficiently. This pioneering spirit is what drives their mission to not only revolutionize energy storage but also educate others about its potential. Emtel’s embarked on bringing this technology from proven success in international markets to the heavy energy-using United States, supported by robust backing from prominent investors like the Royal Family of Dubai.”
