Energy storage and floating offshore wind will benefit from £68m and £20m, respectively.
The investment is part of the government’s £1bn Net Zero Innovation Portfolio.
The Energy Storage Innovation and the Floating Offshore Wind Innovation competitions will be formally open to bids in spring 2021.
Energy minister Anne-Marie Trevelyan said: “The UK’s energy innovators have been vital to us becoming a world-leader in clean green technology, helping us to go further and faster as we tackle climate change.
“This funding will allow us to develop new ways of unlocking the potential for green energy as we continue making big strides towards our goal of eradicating our contribution to climate change by 2050.”
