A hospital in Lincolnshire has been awarded £23m to make energy and power upgrades.
Boston Pilgrim Hospital has received the funding as part of the latest round of the government's Public Sector Decarbonisation Scheme.
The money was set to be used to pay for an electrically powered heating and hot water system across the site of the hospital.
Mike Parkhill, from Lincolnshire Community and Hospitals NHS Group, said the funding would help to reduce the hospital's reliance on fossil fuels for energy.
'Sustainable future'
He said: "This funding brings us closer to achieving our net-zero target by 2040, while also reinforcing our commitment to provide modern and more energy efficient environments for our patients and staff.
"By significantly reducing carbon emissions and lowering our reliance on fossil fuels, we're investing in a more sustainable future for Boston.
"We are also working on future bids for our other hospital sites across Lincolnshire."
The investment comes weeks after the hospital unveiled the first half of its new Emergency Department, with the completed works expected to cost between £45m and £49m.
The scheme for the site in Sibsey Road, Boston will also be delivered by Salix on behalf of the government's Department for Energy Security and Net Zero.
Ian Rodger, Salix Director of Public Sector Decarbonisation, said: "We have no time to stand still when talking about climate change and reducing our carbon emissions is key.
"This funding will not only help the hospital site achieve its net zero ambitions, but it will make the buildings better and more comfortable for the patients, staff and everyone who uses them."
