    JCB hits 368mph at Bonneville: hydrogen ICE performance insights for engineers

    First reported on The Construction Index

    30 Second Briefing

    JCB’s Hydromax hydrogen-powered streamliner has reached 368.347mph at the Bonneville Salt Flats, breaking the Southern California Timing Association Blown Gas Streamliner (AA/BGS, 500+ cubic inches) class record of 348.342mph set by the Spectre Streamliner in 2010. Driven by Wing Commander Andy Green OBE, the car uses two production-based JCB hydrogen internal combustion engines now being pushed towards a combined 1,600hp. The team is preparing the vehicle for an FIA-sanctioned outright world land speed record attempt next week, positioning hydrogen ICE as a zero-emission, high-load power option for heavy plant.

    Technical Brief

    • Hydromax runs two production-based JCB hydrogen ICE units, not bespoke race-only prototypes.
    • Powertrain tuning is being progressively increased towards the engines’ full combined 1,600 hp capability.
    • Record was certified under Southern California Timing Association AA/BGS (500+ cubic inches, blown gas) rules.
    • New class mark exceeds the prior SCTA AA/BGS record by 20.005 mph.
    • AA/BGS class record had stood unbroken since 2010, with no improvement for 16 years.

    Our Take

    JCB’s use of the Hydromax hydrogen engine at Bonneville gives it a high‑profile demonstrator that complements its more conventional fleet upgrades seen in our database, such as the LiveLink telematics enhancements for Hi‑Viz Loadalls, signalling that alternative fuels are being explored alongside digital efficiency gains rather than instead of them.

    For quarrying and concrete operators already buying JCB equipment – like Base Concrete’s recent TM420 purchase – a 368mph hydrogen record run by a UK manufacturer helps de‑risk perceptions around hydrogen combustion technology, making it easier to justify trialling low‑carbon powertrains on loaders and telehandlers in future procurement cycles.

    Paladin rare earth recycling expansion: supply-chain takeaways for engineers

    Rare earth recycler Paladin EnviroTech is investing over US$5 million to expand its Ohio recovery facility from 40 to 150 tonnes per year by Q3 next year, targeting end-of-life hard drives, EV motors, generators, MRI machines and wind turbines containing neodymium, praseodymium, terbium and dysprosium (up to ~16% Dy in MRI magnets). Working with Western Digital and Critical Materials Recycling, Paladin uses a non-acidic selective leaching process achieving 97–98% rare earth recovery and about 90% total value recovery, feeding mixed rare earth oxides back into Western magnet supply chains.

    Breedon’s new CEO from 2027: strategic implications for materials project teams

    Breedon has appointed current chief financial officer James Brotherton as its next CEO from 1 January 2027, succeeding Rob Wood after a 12-year tenure with the construction materials group. Brotherton has been CFO since 2021 and co-developed Breedon’s “expand and improve” strategy, which underpinned its expansion into the US market and transfer to the London Stock Exchange’s main market. Wood, who became CEO in 2021, will step down from the board at end-2026 but remain an employee to support the leadership transition until September 2027.

    Chryso–Ecocem low‑carbon cement system: mix design notes for concrete engineers

    Saint-Gobain’s Chryso and Ecocem have launched a combined low‑carbon system pairing Ecocem ACT cement, which cuts cement emissions by up to 70%, with Chryso’s new superplasticiser EnviroMix 3150 ACT, formulated for this binder chemistry. The admixture–cement combination enables concrete mix designs achieving over 50% carbon footprint reduction, meeting GWR5 and above, while maintaining high flowability, low viscosity at low water–cement ratios, and workability retention beyond 90 minutes without segregation. On the former John Lewis HQ refurbishment in London, around 1,300 m³ of C20/25 and C30/37 ACT concrete is being pumped using EnviroMix 3150 ACT to validate performance under site conditions.
