A lot of companies are involved in a lot of renewables tech research. That doesn't mean that any particular one is going to be profitable. The vast majority are going to be big failures.
Wave power's track record so far has been subpar to say the least. And looking at their diagrams, I can't imagine that they're not headed straight for the same fate. Even if we assume that their numbers aren't overly optimistic, their design looks like it would involve several times more steel per nameplate capacity than a wind turbine tower. And they're operating in a much harsher environment. No rotors, but they're dealing with major hydraulic pumping instead. It just doesn't look like a winner to me.
If it was my job to have a go at wave power, I can't imagine going for anything involving large amounts of structural steel or hydraulic pumping; I'd keep it simple and just go for a grid of cables (potentially a high tensile strength UV-resistant plastic), anchored at the edges to keep tension up across the whole grid, with the only slack available involving the grid pulling on regularly spaced springloaded reels (the rotation thereof generating electricity), with any combination of floats, drag chutes and weighs/anchors to cause the needed tug from the movement of water. No pumps, no hydraulic fluid, no large compressive-loaded structures, just a tensile structure that would be (proportionally) lightweight and easy to deploy.
But hey, it's not my industry
