Skeleton's New Product Cuts AI Data Center Energy Use by 44% and Boosts Computing Power by 40%

Diana Berman — Wed, 28 May 2025 12:08:47 GMT

Skeleton Technologies, a global leader in high-power energy storage, launches GrapheneGPU, a high-performance system designed to solve the key challenge of AI growth: energy inefficiency and power infrastructure limitations. Skeleton’s proprietary Curved Graphene material reduces AI energy consumption by up to 45% and lowers power connection requirements by 44%, while boosting computing performance in FLOPS by 40%.

By cutting energy use and peak power demand nearly in half, these improvements proportionally reduce both capital investments and operational costs in AI infrastructure. GrapheneGPU has successfully completed validation under the most demanding power profiles set by leading hyperscalers. Initial shipments are scheduled from Skeleton’s German facility for June 2025. US manufacturing expansion is scheduled for the first quarter of 2026 to support growing international demand.

Skeleton Technologies Receives Prestigious Louis Schwitzer Award for Contribution to IndyCar Hybrid Platform

Diana Berman — Thu, 22 May 2025 15:29:23 GMT

Skeleton Technologies has been awarded the 2025 Louis Schwitzer Award for its key contribution to the development of the hybrid power unit Energy Storage System (ESS) for the NTT IndyCar Series.

The award was presented to Raoul Fernandes, Senior Project Manager at Skeleton, along with other contributors from Honda Racing Corporation, EMPEL, Ilmor Engineering, INDYCAR, and Dana Inc., for their joint work on a groundbreaking technology that is already transforming the landscape of motorsports.

In 2025, the jury highlighted the development of a new hybrid energy storage system — the first of its kind to utilize a low-voltage energy solution based on supercapacitors. The system made its competitive debut in July 2024 at the Mid-Ohio race and is now officially used in all rounds of the IndyCar season, including the upcoming 109th running of the Indy 500, set to take place this Sunday.

Skeleton developed and supplied a critical component of the hybrid platform — the energy storage unit based on proprietary supercapacitor technology. This solution ensures ultra-fast charging and power delivery, which is essential for performance in high-speed racing environments. The technology not only boosts efficiency and responsiveness but also contributes to a more sustainable and environmentally conscious approach to motorsport.

Skeleton Technologies is proud to announce its inclusion in the prestigious list of the World’s Top GreenTech Companies of 2025, as compiled by TIME and data firm Statista. Skeleton was ranked 30th out of 250 corporations globally and is the first European company in the Energy Storage & Distribution category. Skeleton is also the only supercapacitor manufacturer to be recognized in this global ranking.

“It is a great pleasure to be included in theTIME Magazine’s World’s Top GreenTech Companies of 2025, especially as the first European company in the energy storage category and as the only supercapacitor manufacturer in the Energy Storage category. This is a major recognition of not only our technological leadership but also our team’s relentless work. We have made supercapacitors the key enabling technology in mission-critical applications, from stabilizing the German grid to supporting nuclear fusion, or making AI data-centres more energy-efficient while increasing their computing power. Our solutions are the backbone of both the AI and the green energy revolution, and with the presence of several AI companies in this ranking, TIME also underlines these two revolutions are deeply intertwined,” said Taavi Madiberk, CEO and Co-founder of Skeleton Technologies.

The TIME World’s Top GreenTech Companies of 2025 is the publication’s first-ever global ranking of climate technology firms and was developed in collaboration with Statista, a respected data and analytics firm. The selection process evaluated over 8,000 companies, with only 250 making the final list— based on their positive environmental impact, financial strength, and innovation.
