The next phase of a government funding programme is offering up to £9 million to help develop innovative energy technologies.
The Energy Entrepreneurs Fund (EEF) will look to assist small-to-medium sized enterprises in the public or private sector working on energy efficiency, power generation, heat and energy storage projects.
There also needs to be a plan in place for the technology to reach the market at a reasonable price with potential for cost reduction in the future.
The companies that are selected will also get additional financing to help them maximise the commercial impact of the grant.
So far, 86 innovative, low carbon projects have been awarded grants totalling around £38.3 million.
Expressions of interest are required by 5pm on 25 November 2016 for the first round of applications. The second round closes at 5pm on 20 January 2017.
