There are some technical details about flow rates and head height in section 4.8 (p. 85/88) of this document: http://tidallagoon.opendebate.co.uk/files/TidalLagoon/DCO_Application/6.2_4.PDF http://tidallagoon.opendebate.co.uk/files/TidalLagoon/DCO_Ap... One other thing I noticed upon briefly skimming is they're considering installing turbines which can also be used as pumps. I suppose in principle, at the cycle of the tide when the head is low and the plant isn't producing power, you could use the same facility as pumped storage. There's also a rather florid promotional video here, if anyone's interested: https://www.youtube.com/watch?v=mXEmHDQtXnw https://www.youtube.com/watch?v=mXEmHDQtXnw
