Clean Hydrogen: How Endeavour Powers Green Data Centres

Rising energy demand from AI workloads is intensifying pressure on data centre operators to secure reliable and lower-carbon power sources.

According to the International Energy Agency (IEA), data centres currently consume around 1.5% of global electricity, a figure expected to reach 3% by 2030.

Meeting this demand while reducing emissions remains a central challenge for the sector.

US-based infrastructure innovation firm Endeavour is positioning hydrogen as part of the solution, with a new system designed to support continuous, low-carbon energy supply for data centres.

Hydrogen production for data centre power

Endeavour’s technology, known as Pact, is a methane cracking system that produces hydrogen fuel while capturing carbon as a solid by-product.

Unlike electrolysis-based hydrogen production, which requires significant electricity input, Pact uses a continuous-flow, closed-loop process to extract hydrogen from methane sourced from natural gas or biomethane.

Jakob Carnemark, CEO and Founder of Endeavour, says: “There have been few low-carbon options that can be deployed quickly at the scale and cost needed for AI campuses and heavy industry. The Pact system fills that gap.”

Jakob adds that the system is designed to support energy-intensive environments such as AI data centres while avoiding the emissions associated with conventional hydrogen production.

Reducing emissions through carbon capture

A key element of the Pact system is its approach to carbon management.

Instead of releasing carbon dioxide, the process converts carbon into solid graphite during production.

This is enabled by a low-temperature catalytic reactor developed over more than a decade.

Methane is passed through the reactor, separating hydrogen while transforming residual carbon into a usable material.

By eliminating direct emissions and reducing reliance on high-energy processes, the system aims to lower the overall carbon intensity of hydrogen production.

The technology has been tested in collaboration with industrial hydrogen specialist EBNER at its facility in Ohio.

Herbert Gabriel, Managing Director of EBNER, says: “This is an important milestone for the hydrogen industry. 

“The Pact system dramatically reduces the environmental footprint of conventional fossil-based hydrogen and overcomes the scalability challenges of electrolysis-based systems.”

Turning carbon into a resource

Beyond energy generation, Pact’s production of solid carbon introduces an additional commercial dimension.

The system produces a fine graphite material that can be used across multiple industries, including semiconductors, construction and electrical infrastructure.

Juzer Jangbarwala, Chief Technology Officer for Pact at Endeavour, explains: “Instead of storing carbon or releasing it into the atmosphere, Pact is creating the foundation for a carbon materials platform backed by a growing patent portfolio of clean chemical synthesis and functionalisation technologies.”

Juzer highlights the potential for these materials to replace imported graphite, which could further improve the environmental profile of the process by reducing supply chain emissions.

Modular deployment for AI infrastructure

Endeavour has designed Pact as a modular system capable of scaling alongside data centre developments.

The technology can operate at capacities as small as 5MW or scale to gigawatt-level deployments, making it suitable for both individual facilities and large hyperscale campuses.

It can also be integrated with existing power systems, including on-site generation technologies such as gas turbines or fuel-based generators.

Hydrogen is produced on demand, reducing the need for large-scale storage or transport infrastructure.

This approach aligns with the operational requirements of data centres, where consistent power availability is critical and infrastructure must scale with demand.

Supporting next-generation data centre energy

As AI workloads increase power density and drive higher energy consumption, data centre operators are exploring a wider range of energy solutions beyond traditional grid connections.

Hydrogen-based systems such as Pact offer a potential pathway for on-site or distributed power generation with lower emissions, particularly in regions where renewable energy supply is constrained or inconsistent.

Endeavour’s approach focuses on delivering continuous power while addressing both cost and environmental considerations.

While large-scale deployment remains in early stages, the system reflects ongoing efforts within the data centre sector to balance performance, scalability and sustainability as digital infrastructure continues to expand.
