ZIGRID Project: Work Performed and Main Achievements
Introduction
A major achievement in the ZIGRID project has been the transition to a stand-alone power module, significantly improving efficiency, adaptability, and scalability. This redesign, which stemmed from subsystem optimization and certification requirements, has led to efficiency gains exceeding 50% and positioned ZIGRID for successful pilot implementation in AI DataCenters. The combination of iterative testing, real-world system validation, and supplier coordination has positioned ZIGRID ahead of schedule in key technical areas.
WP1: Subsystem Development and Optimization
• Power Module Redesign:
o The power module is upgraded enhancing efficiency, scalability, and simplifying certification.
o The redesigned module includes additional cylinders, leading to smoother and more continuous power production.
o Optimization of drivetrain and hydraulic components improved torque, RPM efficiency, and overall energy conversion.
• Subsystem Interfaces and Real-World Testing:
o While Digital Twin simulations have played a role in system refinement, real-world testing at facilities like BAETTR and the Jönköping Engine Lab provided critical insights that shaped the final design of the upgraded power module.
o Physical validation of cylinder performance and heat management led to major design improvements.
WP2: IoT Platform Implementation
• IoT Pre-Study and Standard Platform Selection:
o The pre-study led to the selection of a standard IoT platform, reducing development effort and accelerating deployment.
o Integration of sensors with PLCs ensures continuous, real-time data availability.
o Live IoT data streams from power modules now support real-time performance tracking and predictive maintenance.
WP3: System Demonstration and Certification
• Pilot Shift to liquid cooled DataCenters:
o Given the upgraded power module’s enhanced adaptability and efficiency with up to 50% higher energy conversion—the pilot will likely shift to an AI DataCenter.
o This strategic pivot is driven by delays in the Green Hydrogen roadmap across the EU and US, while AI DataCenters represent an immediate, high-growth market for ZIGRID’s technology.
o The ability to integrate waste heat recovery into liquid-cooled AI infrastructures positions ZIGRID as a key player in this rapidly expanding sector.
• Certification Progress:
o Collaboration with RISE progressed smoothly, with ongoing work on meeting EU directives and preparing certification documentation.
o Early supplier selection ensures that certified components align with quality and scalability requirements.
