UK to greenify Type 26 frigate fleet to boost global presence
March 17, 2022, by Fatima Bahtić

Royal Navy’s Type 26 frigates HMS Glasgow and its seven sister vessels are being fitted with selective catalytic reactors to reduce their impact on the environment.
The new selective catalytic reactor, which is a box about three metres tall and two across equipped with large-scale filters/converters, will allow the submarine-hunting ships to operate in some of the most environmentally-sensitive parts of the world as well as meet the standards set in heavily-regulated waters such as the North Sea and off the Eastern Seaboard of the USA.

When explaining how the reactor functions, Royal Navy noted that as exhaust fumes from the diesel generator pass through, a urea solution is sprayed in, causing a chemical reaction to reduce the majority of nitrogen oxides emissions.
Instead of the gases – harmful to the ozone layer, a key component of acid rain and a factor in global warming – the process instead produces water and oxygen.
“The urea we will use is effectively the same ‘Adblue’ solution that you see sold in fuel station forecourts for trucks and vans,” explained Commander Richard Wadsworth, a senior marine engineer officer with the Type 26 frigate programme.
