The Lower Thames Crossing (LTC) is a National Highways project that will build a new road connecting Kent, Thurrock and Essex through a tunnel beneath the River Thames. It will provide much-needed new road capacity across the river east of London, alleviating congestion on the Dartford Crossing. Three Delivery Partners have been appointed to deliver the three main components of the project - Kent Roads, Tunnels & Approaches and Roads North. National Highways has designated LTC a pathfinder project that will explore carbon neutral construction. Low Carbon Hydrogen is a key element in LTC's strategy to deliver its carbon reduction targets and a key objective of this procurement is to enable a significant reduction in the use of diesel on the programme by enabling the use of hydrogen powered plant, machinery and generators. The procurement covers the supply, delivery, storage on site and dispensing of Low Carbon Hydrogen for use by the LTC appointed Delivery Partners to fuel their construction plant and equipment. Making hydrogen easily available could displace a significant amount of the diesel forecast to be used during construction. This will be an 8 year contract (consisting of a period of preparation and readiness to supply hydrogen and then 5 years of hydrogen supply) with the option to extend by up to two additional years (1+1) in the event this is required. The option to extend is included to mitigate the impact of delays to the LTC programme The Low Carbon Hydrogen contract is enabled for use by Lower Thames Crossing's Delivery Partners and by National Highways' contractors Read full description ## CPV classification Industrial gases Source Contracts Finder (UK) [View official notice](https://www.contractsfinder.service.gov.uk/notice/482d23a8-5cc8-45ef-bc1b-67cd79014c13) Never miss a tender like this again Get AI summaries, deadline alerts and a bid pipeline for tenders matched to your business.
