Endeavour's Pact: A new era for hydrogen-powered AI data centres. Key points. * Endeavour's Pact system produces hydrogen fuel and solid carbon through methane pyrolysis. * Pact is designed for continuous, low-carbon energy for AI data centres and heavy industries. * Solid carbon output can be sold for industrial applications, reducing carbon emissions. * The system addresses scalability and low-carbon energy supply challenges in the industry. Endeavour has unveiled its innovative system, Pact, aimed at providing low-carbon hydrogen fuel for AI data centres and heavy industrial applications. By utilizing methane pyrolysis, or methane cracking, Pact separates hydrogen from methane feedstocks, resulting in solid carbon as a byproduct instead of carbon dioxide. This method presents a significant improvement over traditional hydrogen production methods, which often result in high carbon emissions. The company positions Pact as a continuous-flow, closed-loop system that can run on both natural gas and biomethane, catering to the growing demands of hyperscale AI workloads. Key to Pact's appeal is its potential to deliver a round-the-clock, dispatchable energy supply, which is critical for large AI data centre campuses facing increasing operational demands. By being capable of immediate hydrogen production, Pact reduces the need for extensive hydrogen storage and transportation, which often pose logistical challenges due to hydrogen's low volumetric energy density. The modular design of Pact allows it to support a wide range of generator systems, ranging from small industrial sites to large campus developments. A significant advantage of Pact is its ability to convert carbon into solid graphite, a material that is increasingly in demand for various industrial uses and battery supply chains. This innovation not only provides a sustainable solution for hydrogen production but also offers a marketable byproduct that could contribute to a circular economy model in industrial applications. According to Endeavour, their methane pyrolysis system could potentially result in lower lifecycle greenhouse gas emissions compared to electrolytic hydrogen, depending on various factors including feedstock and methane leakage during production. The testing of Pact was conducted in partnership with EBNER, a company specializing in industrial heat treatment equipment. Both companies view Pact as a pivotal development in the hydrogen industry, particularly in terms of overcoming the scalability challenges associated with electrolytic hydrogen systems. EBNER's managing director labeled the advancement as a milestone, highlighting the environmental benefits compared to conventional fossil-based hydrogen. Endeavour's approach to commercializing Pact involves exclusive partnerships with Edged Infrastructure, focusing on integrated campus projects. Although the system's market introduction will depend on demonstrating sustained operational performance and economic viability under varying conditions, there is optimism about its potential to meet urgent low-carbon energy needs in AI and heavy industry. As highlighted by Endeavour's founder, the market currently lacks accessible low-carbon options that can be rapidly deployed at the necessary scale for demanding applications. In conclusion, Endeavour's Pact system represents a promising leap forward in the hydrogen sector, leveraging innovative technology to address the pressing energy needs of the AI data centre industry while simultaneously contributing to carbon reduction efforts.

Endeavour unveils Pact: A revolutionary hydrogen fuel system to power AI data centers. Key points. * Endeavour's Pact technology provides low-cost, carbon-neutral hydrogen fuel for AI data centers. * The system co-produces high-quality graphite, offering environmental and economic benefits. * Pact addresses scalability issues of traditional hydrogen systems with a modular design. * Endeavour aims to redefine infrastructure for AI while supporting climate change mitigation. On March 16, 2026, Endeavour announced an innovative new technology called Pact, aimed at providing a sustainable energy solution for AI data centers. This hydrogen and solid carbon co-production system promises to deliver affordable, clean, gigawatt-scale energy necessary for the demanding requirements of AI cloud providers. As the need for energy-efficient solutions grows amidst a widening power gap, especially in the realm of AI, Pact claims to fill this critical void by enabling continuous and carbon-neutral power generation derived from natural gas and biomethane feedstocks. The announcement was made during a press release highlighting how the Pact system uses a continuous-flow, closed-loop methane cracking process. This advanced technology separates hydrogen from methane while capturing the resulting carbon in the form of solid graphite. Notably, this method has been developed over a decade and is reportedly more environmentally friendly than traditional electrolysis methods for producing 'green' hydrogen. Jakob Carnemark, CEO and Founder of Endeavour, emphasized the innovation's significance, particularly in addressing the lack of low-carbon options that can be quickly deployed at the necessary scale. He stated that the Pact system represents a transformative step toward clean hydrogen fuel for technology infrastructure, offering a solution that not only meets operational demands but also contributes to reducing the environmental impact of energy consumption. Testing of the Pact technology took place in collaboration with EBNER, a leader in hydrogen production technology, at their headquarters in Wadsworth, Ohio. EBNER's Managing Director, Herbert Gabriel, described this development as a milestone for the hydrogen industry, highlighting its potential to significantly lower the environmental footprint associated with traditional fossil-based hydrogen production. Pact further enables the creation of revenue-generating pathways through various carbon materials, including advanced graphite used in semiconductors and low-carbon concrete. This multifunctional aspect not only enhances economic viability but also promises a net carbon-negative energy source as it replaces energy-intensive graphite imports. The system's design allows for flexibility, supporting generator systems ranging from 5 MW to over 1,000 MW, which is crucial for scaling up in response to the increasing energy needs for AI technologies. Moreover, the integration with Endeavour's TurboCell power system creates a just-in-time fuel production mechanism, alleviating many challenges traditionally associated with hydrogen energy systems. As the push for sustainable energy solutions intensifies, Endeavour's Pact provides a promising avenue for powering AI data centers while contributing to the wider goals of carbon neutrality and climate change mitigation. The company's vision extends beyond merely reducing environmental harm; it aims to create regenerative systems that restore local resources while delivering global benefits. With its focus on innovation and sustainability, Endeavour positions itself at the forefront of the clean energy movement. March 16, 2026 at 01:20 PM New York, United States
