Wave energy is one of those things that only works at the "ghetto contraption I built with crap I had lying around" scale. Combine something that pumps, two check valves, some hose and creative plumbing (alternatively, replace creative plumbing with a lever and hydraulic cylinder) and you've got a really low pressure pump. From there it's just physics. Doing this kind of thing at scale just doesn't work. Between expensive engineers, permitting, code, surveys, OSHA, etc. etc. etc. there's no scale at which you can do this where you more than break even generating eletricity. Electricity travels great so you're competing with all sorts of other sources. It just doesn't work. But if all you want is to pump enough water into a tank so you can hose bird crap off your dock and you want to avoid digging a 300ft trench for a water line at the same time it works great. If you need real power somewhere remote go solar/wind. If you need better uptime than that then add lead acid to the mix. But once you start breaking into mid-range power needs (think gravel pit mine running crushers or something) it's hard to beat diesel.
