Beka indicators help to refuel green buses

July 2006 Operator Interfaces, Switches & Relays

Beka Associates' intrinsically safe indicators and panel lamps are being used at London's first hydrogen filling station in Hornchurch near Romford.

This BP filling station has been built to refuel three first generation Daimler Chrysler fuel cell powered buses being operated by London Buses as part of the pioneering CUTE (Clean Urban Transport Europe) project involving trials in 11 European cities from Stockholm to Madrid. This EC co-funded two year project will assess the day-to-day performance of fuel cell powered vehicles in a wide variety of conditions, with the long-term aim of reducing urban air pollution and noise.

Initially operating alongside conventional double-decker buses on Route 25 between Oxford Circus and Ilford, when the field trial is well established London Buses intend to run these fuel cell buses on their other routes to fully test their operational and environmental effectiveness.

The demonstration BP filling station is supplied with liquefied hydrogen by BOC from its manufacturing plants in Holland and France via a 2,5 tonne road tanker. At the filling station the liquefied fuel is stored in an underground vacuum insulated vessel, from which buses are refuelled with a 40 kg load of gaseous hydrogen. Each refuelling provides at least 125 miles of urban operation.

Beka intrinsically safe loop powered indicators are used to display level and pressure on the Liquid Hydrogen Delivery Panel, which also contains Beka intrinsically safe LED indicator lamps and a Beka alarm sounder.

Bus refuelling is fully automated and also includes two Beka loop powered indicators showing the pressure and temperature within the six gas storage cylinders that are mounted on the bus roof adjacent to the fuel cells.
