Balfour Beatty has successfully achieved a 26% reduction in carbon emissions during road tests by retrofitting two salt spreader HGVs with hybrid hydrogen technology. This initiative is part of the M77 Hydrogen project, aiming to establish Scotland's first construction hydrogen hub. By installing the hydrogen system on vehicles like impact protection vehicles, the company is working towards lowering emissions. Balfour Beatty has also set up green hydrogen supply, storage, and refuelling infrastructure, leveraging collaborations with ULEMCo, Logan Energy, and PlusZero. The project, funded partially by the Scottish Government, has highlighted the ease and effectiveness of retrofitting existing vehicles with hydrogen technology. Despite the benefits, challenges such as retrofitting costs and limited hydrogen refuellers persist. The company emphasizes the flexibility of vehicles to switch to diesel when hydrogen is unavailable as a risk reduction measure. Overall, the project demonstrates a positive step towards sustainability and carbon reduction in the construction industry through innovative hydrogen technology.
