Whatever happened to wave power?

Wave energy has not developed as fast as tidal stream technology and a new report asks, what went wrong with the UK support programme? The message seems to be that it was expected to become commercially viable too fast - that will take time. And for the moment, with the drive to ever sharper market competition, its prospects do not look too good.

Energy transitions in the UK

UK R&D funding options in energy need to be reconfigured with green heat systems being a high priority, although some still look to fossil carbon capture and storage (CCS), and nuclear, as two new reports illustrate.

The Helm energy cost review

Dieter Helm's review of UK energy costs suggests that radical changes are needed - a shift to a universal carbon price and a unified Equivalent Firm Capacity auction process for all energy technologies, with balancing systems requirements being included. It sounds simple, but the devil will be in the practical application - will sensible prices and enough balanced low carbon capacity really emerge from this market revamp?
