The title of this post, is the same as that of this article on Solar Power Portal.

Taking the title of this article at face value, it is probably good practice for a company like Gravitricity to take on someone like Juliet Davenport, as they move to the next phase of their business.

The article also mentions Gravitricity's developments in the storage of hydrogen and heat.

This paragraph also mentions a new development.

Gravitricity is now developing plans for a full-scale energy storage project at a recently closed coal mine in mainland Europe, in what will be the start of a pipeline of projects worldwide.

That does seem to be good news.

Note that it is recently closed coal mine. This is surely for the best, as who knows what the state of long-disused mine will be? My project management and engineering knowledge, says that an orderly handover can reduce the cost of the installation.
