HyKit hydrogen bowsers and ‘shipping sunlight’: practical notes for site engineers
Reviewed by Joe Ashwell
First reported on The Construction Index
30 Second Briefing
HyKit has launched its first mobile hydrogen refueller – a trailer‑mounted “hydrogen bowser” – aimed at supplying fuel to off‑grid construction sites and plant. Executive chair Jo Bamford outlines plans for a global hydrogen supply chain spanning production, compression and on‑site dispensing, targeting heavy equipment such as excavators, generators and site vehicles. For contractors, the concept removes dependence on fixed refuelling stations and opens a pathway to trial hydrogen plant on existing projects without major infrastructure works.
Technical Brief
- Trailer-mounted HyKit unit integrates onboard hydrogen storage, compression, metering and hose reel in a single bowser.
- Refueller is sized to follow typical diesel bowser logistics, fitting standard site access and haul roads.
- HyKit’s model includes upstream production, tube‑trailers for bulk transport, and final on‑site decompression/dispensing.
- Bamford targets heavy plant duty cycles, designing flow rates to minimise refuelling downtime versus diesel equivalents.
- System is intended to operate as a temporary asset, moving between short‑term or phased worksites.
- HyKit is positioned as fuel‑as‑a‑service, with contractors buying kilograms of hydrogen rather than hardware.
- Strategy assumes centralised hydrogen hubs feeding regional construction clusters via road‑based distribution.
- For similar projects, mobile hydrogen bowsers could de‑risk early trials of fuel‑cell or H2‑ICE plant fleets.
Our Take
Hydrogen appears in only a small subset of the 842 Infrastructure stories in our database, but several of those—such as Galliford Try’s green hydrogen generator for National Highways—also focus on temporary or mobile power for construction compounds, signalling a niche where HyKit’s hydrogen bowsers could find early traction.
Recent pieces on natural and geologic hydrogen, including MAX Power Mining’s Lawson project and GeoRedox–Canada Nickel’s stimulated hydrogen well, show upstream supply concepts maturing; HyKit’s focus on distribution hardware positions it at the opposite end of the value chain, where project risk is more about deployment logistics than subsurface uncertainty.
With 24 hydrogen keyword-matched pieces in our coverage, most centred on fixed industrial or manufacturing users (for example, Dalkia UK’s Barrow Green Hydrogen project feeding Kimberly-Clark), HyKit’s mobile refuelling model targets a less crowded segment that could bridge the gap while dedicated hydrogen pipeline and grid infrastructure catch up.
