  • FLOPS vs Megawatts: Who’s Winning in 2026 Supercomputing?

    The article provides analysis and commentary on 2026 supercomputing buildouts, contrasting public exascale systems with hyperscaler AI campuses. It is not a first-time announcement by one entity, but a roundup of recent developments and milestones.

    • The piece compares public TOP500 systems and private hyperscaler AI campuses, highlighting that private builds are measured in hundreds of megawatts to gigawatts rather than HPL scores.
    • It cites several recent milestones, including Microsoft’s Wisconsin Fairwater campus, xAI’s Colossus 2, OpenAI and Oracle’s Stargate, and Meta’s Prometheus nuclear power agreements.
    • It also notes Alice Recoque installation in France under a €354.8 million EuroHPC JU contract with Eviden and mentions the next TOP500 list at SC26 in November.
  • Honda-LG ES begin ESS cell production at retooled Ohio EV cell facility

    L-H Battery Company has announced the commencement of lithium-ion cell production at its Jeffersonville, Ohio plant, shifting initial output from EV cells to stationary energy storage system applications.

    • Production began this month at the Jeffersonville, Ohio facility after a construction and workforce development effort that started when the JV was established in 2023.
    • The plant was originally conceived for EV cells but is now focused on ESS applications; LG ES Vertech will integrate the first cells into complete ESS solutions, and the company says the batteries will serve residential, commercial and industrial, and utility grid markets.
    • Local reporting had claimed the plant would make batteries for AI data centre-specific ESS solutions; Caroline Ramsey said that was “just not accurate.”
    • The article also places the announcement in the context of broader US battery manufacturing shifts, including Panasonic, LG ES, Ultium Cells, Samsung SDI, SK On, Ford Energy, and Peak Energy.
  • SpaceXAI wants to compete on AI infrastructure, not just AI models

    SpaceXAI has announced a new unified company strategy combining SpaceX and xAI to pursue orbital AI infrastructure.

    • The company said it will combine Grok models, Colossus GPU clusters, Starlink networks, and SpaceX launch capabilities to build data centers in space powered by solar energy.
    • It said it will deploy AI compute satellites as early as 2028 and begin work on the 11-million-square-foot Gigasat factory as soon as late 2027; the article also cites $55 billion for that factory investment.
    • The article references prior disclosures that SpaceX spent $12.7 billion on AI in 2025 and that Anthropic and Google signed access deals worth $1.25 billion per month and $920 million per month respectively for Colossus.
  • Streamlining ARM data access with AI-ready infrastructure

    The U.S. Department of Energy’s ARM User Facility has announced ongoing upgrades to the ARM Data Center to support AI-ready scientific workflows.

    • ARM is adding GPUs, replacing its file server with an AI-ready storage platform, and expanding cybersecurity/network controls to support data access and AI tools.
    • The facility plans to add 25 to 30 new GPUs over the next two to five years and 2 to 3 petabytes of storage for vectorized content over the next three years; ADA is expected in July 2026.
    • The article also describes ATLAS, a shared platform for model inference, semantic representation, workflow coordination, and secure access, tied to DOE’s American Science Cloud and Genesis Mission.
  • Sphere 3D enters 30MW co-mining agreements with Bitdeer

    Sphere 3D has announced new co-mining agreements with Bitdeer Technologies Group for 30MW of capacity across three data center sites in Tennessee and Kentucky.

    • Bitdeer will deploy Sealminer A2 Pro Air hardware at Sphere 3D’s sites, with the two companies sharing net mining proceeds under separate agreements.
    • Each agreement has an initial one-year term and may be renewed for one additional year; financial terms were not disclosed. Sphere 3D said the move lets it use available power capacity while evaluating AI and HPC opportunities. The company also said it closed its business combination with Cathedra Bitcoin in June 2026, engaged EA Advisors in June, and plans to rename itself DarkHorse Technologies Inc. subject to shareholder approval.
  • Modeling framework reveals grid battery aging effects

    Oak Ridge National Laboratory has announced research using high performance computing and physics-based modeling to analyze battery aging and improve the design of megawatt-hour grid storage systems.

    • ORNL researchers are coupling HPC with a physics-based modeling framework to evaluate how operating strategies affect battery aging over 500-1,000 cycles, with results in days instead of weeks.
    • The model scales from cell-level to module- and pack-level performance, simulates more than 10,000 cells at once, and is intended to optimize electrical architecture, control strategies, and operating schedules; the work was funded by DOE’s Office of Electricity and supports the Genesis Mission.
    • The research found different degradation pathways for frequency regulation versus energy-cost reduction use cases, and noted that low-voltage systems showed more aging variation than high-voltage systems.
    • The team received a Best Paper Award at the IEEE Electrical Energy Storage Application and Technologies Conference earlier this year for the work describing the project.
  • Aalo Atomics’ Test Reactor Reaches Criticality at INL, Fourth DOE-Authorized Advanced Reactor by July 4

    Aalo Atomics has announced that its Aalo-X Critical Test Reactor (CTR), dubbed Project First Light, reached criticality at Idaho National Laboratory on July 4, making it the fourth DOE-authorized advanced reactor to achieve criticality in the recent federal reactor testing push.

    • DOE said Aalo’s test reactor successfully completed a zero-power fueled criticality demonstration at INL under the Reactor Pilot Program; Aalo told POWER the CTR reached criticality at 12:20 a.m. MT on July 4.
    • Aalo CEO Matt Loszak said criticality paves the way for the Aalo Pod to power commercial data centers after NRC authorization; Aalo said the 10 MWe Aalo-X design supports construction and licensing in 2027 and operations/safety demonstrations in 2028.
    • The article also says Aalo has begun work on Project Ascension, a second reactor on the INL campus, with excavation and earthwork completed and first concrete being prepared; Aalo expects to finish it by end-2026 and make commercial-scale electricity in 2027.
