Verdant Power - pluses and minuses


In an earlier post, I promised to write more about my recent visit to Verdant Power...but first, don't let the picture fool you - there's a 19 hour non-slack period in this stretch of water, running at up to 3 m/s.

On the plus side:
  • Verdant's got kit in the water (at least I think it was in the water, the East River's a bit murky)

  • Verdant has made real progress with the technology, through umpteen refinements

  • It's got further development plans, both in the East River and elsewhere

  • The design is simple, with relatively few things to go wrong, and may be scalable

  • The site is fantastic, with well-behaved bi-directional flow at up to 3 m/s, within a 4-iron of the United Nations building (well, one of Tiger Woods' 4-irons), and better still a short taxi ride from Wall Street

  • The company's already raised some significant finance (exploiting that taxi ride from Wall St)


On the "still to do" side:
  • Installation is still difficult and expensive

  • Labour costs in New York are high

  • Reliability is still unproven, despite time in the water (due in part to the fast technology iterations)
  • Revenue support mechanisms in the US are not as clear as in the UK


On balance, I was very impressed with the company's progress, technology and concept. There's still a fair way to go, but it seems to me that there could well be commercial applications for the technology, particularly in more accessible run-of-river style applications.

In summary, nice one Verdant!
