The company’s Hyflex generator, fuelled with hydrogen from Air Products, along with a battery energy storage system (BESS), supplied a site in Staffordshire with an estimated 5.2MWh.
Over the course of the self-funded trial, Hitachi says the installation avoided around five tonnes of carbon dioxide emissions compared to conventional diesel generators.
Head of Grid & Power Quality Solutions and Service at Hitachi Energy, Marco Berardi, hailed the capability of the Hyflex system to deliver power where grid capacity is limited or non-existent.
This comes as UK and European regulations aim to accelerate the decarbonisation of construction sites.
Hitachi says policy is catalysing a shift away from diesel, with the Construction Leadership Council aiming to cut its use 78% by 2035.
The company slated green hydrogen as “increasingly central” to the energy transition in the construction sector, which it says comprises over a third of global carbon dioxide emissions.
The Hyflex generator has recently been deployed in two 14-day trials at the Port of Gothenburg, Sweden, one powering the Stena Line ferry and one charging an electric excavator.
