    Liebherr hydrogen loader tests: productivity and duty-cycle insights for engineers

    Liebherr hydrogen loader tests: productivity and duty-cycle insights for engineers

    First reported on The Construction Index

    30 Second Briefing

    Liebherr has started multi-year field trials of its prototype L 566 H hydrogen-powered wheel loader at Bremerhaven fishing harbour, where Georg Grube GmbH is using it for bulk handling of sand, gravel and rock, feeding conveyors and loading lorries in place of diesel machines. The loader is refuelled from a mobile storage station at the Fraunhofer IWES Hydrogen Lab, using green hydrogen generated by regional wind-powered electrolysis. Engineers are tracking whether the hydrogen combustion powertrain matches diesel units on productivity, cycle times and availability, as part of the EU-funded H2B:IMPACT programme.

    Technical Brief

    • Georg Grube GmbH is applying the loader in continuous bulk-handling duty at Bremerhaven’s fishing harbour.
    • Operational envelope includes feeding fixed conveyor systems and managing multiple aggregate stockpiles on a constrained port site.
    • Refuelling relies on a mobile hydrogen storage station positioned within the Fraunhofer IWES Hydrogen Lab premises.

    Our Take

    Liebherr’s hydrogen work in Germany sits alongside its recent R 9300 G8‑E electric excavator launch, signalling that the company is hedging across multiple non‑diesel power options rather than backing a single decarbonisation pathway for quarrying and bulk materials handling.

    With hydrogen and sand both appearing in over 100 keyword‑matched pieces in our database, this trial at the fishing harbour in Bremerhaven is part of a small but growing cluster of infrastructure stories looking at low‑carbon power for high‑throughput aggregates operations rather than just for long‑haul transport.

    The involvement of Fraunhofer IWES Hydrogen Lab suggests Liebherr is targeting compatibility with emerging German hydrogen infrastructure, which could make its equipment more attractive on publicly funded port and coastal projects where local content and research partnerships carry weight in procurement.

    Strabag’s Pfaffensteig Tunnel contract: design and delivery notes for rail engineers

    Strabag and Group company Züblin have secured the design-and-build structural works for the ABS Gäubahn Nord/Pfaffensteig Tunnel in south-west Germany, centred on an 11km twin-bore rail tunnel linking Stuttgart Airport station directly to the Gäubahn line towards Switzerland. About 9.8km will be driven by two TBMs, with conventional tunnelling for the A8 motorway undercrossing and airport connection, plus a 240m cut-and-cover section, retaining structures, railway underpasses and a grade-separated crossing. A 3km surface section will be upgraded and partially realigned for 200km/h operation, delivered under an integrated project delivery model with Ed. Züblin, Wayss & Freytag and Strabag AG sharing tunnelling, structural and earthworks packages.

    National Grid TBM under the Thames: tunnelling design and risk notes for engineers

    A 271.5‑tonne Herrenknecht Mixshield TBM, Caroline, has started driving a 2.2km electricity cable tunnel with a 4m internal diameter beneath the River Thames in Essex for National Grid’s Grain to Tilbury project, delivered by the Ferrovial BEMO joint venture. The drive will pass through variable Thames estuary ground conditions between 35m‑deep launch and reception shafts of 15m and 12m diameter, with tunnelling continuing into 2026 and overall scheme completion targeted for 2029. The new tunnel will replace the 1969 Thames Cable Tunnel and carry new high‑voltage circuits between Grain and Tilbury substations.

    Panama Canal Mixshield undercrossing: design and tunnelling lessons for engineers

    A 13.46m diameter Herrenknecht Mixshield TBM has broken through into the future Balboa station on Panama Metro Line 3 after completing the first-ever TBM undercrossing of the Panama Canal at depths exceeding 60m below sea level. The 5,600kW, 26,616kNm machine, fitted with an accessible cutterhead and more than 4,500 sensors linked via the Herrenknecht.Connected platform, has achieved peak advance of 150 segment rings (about 300m) per month through mixed sandstone, tuff, breccias and basalt. Around 1.5km of the 4.5km twin-track tunnel remains to final breakthrough.
