German energy equipment company Skeleton Technologies has officially expanded into the US market with the opening of a new engineering facility in Houston, Texas.

The company develops graphene-based supercapacitors for the utility and AI data center market. The system is a high-power energy-storage device designed to handle sharp load fluctuations in grids and AI data centers in under a millisecond.

The company claims that its systems enable AI data centers to smooth power demand and reduce energy consumption by up to 45 percent, easing grid impact and improving computing efficiency.

“Access to reliable power is increasingly becoming the primary bottleneck for AI infrastructure expansion in the United States,” said Taavi Madiberk, CEO and co-founder of Skeleton Technologies.

“The unprecedented level of electricity demand and grid strain – especially from AI data centers – makes the US our fastest-growing market by far and is driving massive opportunity for Skeleton Technologies. We’re moving quickly to build local manufacturing, strengthen customer relationships, and position ourselves as a strategic partner in America’s energy security and AI competitiveness.”

The US is already a core market for the company, with more than 100MW of systems deployed nationwide and around half of its revenue generated from North American customers. Skeleton plans to establish US manufacturing capacity for AI data center solutions in the first half of 2026.

The expansion closely follows the opening of two European factories in November 2025, including a $270 million facility in Germany and a $60m plant in Finland.

Before this, in June of last year, the company launched a new power shelf for data centers that uses its graphene-based supercapacitors. Dubbed GrapheneGPU, the shelf can handle power fluctuations associated with GPU use.

Skeleton was launched in 2009 in Tartu, Estonia. Its first customer was the European Space Agency and has seen uptake across the German automotive sector, with use in BMW’s i7 and M-series models.

Investors in the firm include Siemens Financial Services (SFS), Marubeni Corporation, FirstFloor Capital, and EIT InnoEnergy.
