<p>Up to 277kg of hydrogen fuel is safely contained aboard HydroFLEX in 
36 high pressure tanks. This is fed into fuel cells, where a chemical 
process converts the hydrogen and oxygen from the air to generate clean 
electricity.</p>
<p>Innovations such as HydroFLEX can play a significant role in 
achieving the 2050 Net Zero target by encouraging modal shift from road 
transport to rail.</p>
<p>Hydrogen powered trains will support the progressive roll out of 
electrification schemes, as well as delivering clean train travel on 
routes where overhead wires cannot be economically justified.</p>
<p>HydroFLEX is part of a suite of Porterbrook Engineering initiatives 
designed to improve air-quality, reduce carbon and deliver a 
cost-effective and sustainable railway for both passengers and 
taxpayers.</p>
