The vessel, Blackwater Joule, will begin service on the River Thames on July 1 to support patrols and operational work along the non-tidal river.
Equipped for river enforcement, routine patrols, and maintenance, the RS Pulse 63 RIB is part of a plan to cut fleet boat emissions by 50 per cent.
Lisa Craddock, national navigation senior advisor for the Environment Agency, said: “This is a great day for us.
“The Blackwater Joule will allow us to quickly and cleanly patrol along the entire waterway.
“Many of our medium sized craft are approaching the end of their lives, so this new addition is well timed in helping us make long term decisions on the technology we should be investing in.
“Together with the imminent launch of sister ship Electra in East Anglia, this means we can now trial two electric workboats free of charge for the next two years.”
The launch is part of the Zero Emission Workboat Network (ZENOW) project, which aims to deploy the world’s largest network of zero emission electric workboats.
The project will also support the development of the wider clean maritime sector and guide future policy and regulations.
Owners of powered and non-powered boats, including paddleboards, must register annually with the Environment Agency to use the non-tidal Thames.
Registration can be completed by calling 03708 506 506.
