Producing hydrogen from wave energy

"Leading economist Professor Ross Garnaut and two government renewable energy agencies (CEFC and ARENA) are championing the use of hydrogen to exploit Australia’s massive solar and wind resources."

If solar and wind are considered suitable for hydrogen production, would wave energy be suitable as well?

It seems it is and may in fact have some advantages.

"The aim of this paper is to present and evaluate a proposal for designing an off-grid offshore electrolysis plant powered by wave energy. This plant includes PEM electrolyzers, a Reverse Osmosis system to produce water with adequate conductivity, a compression unit to store the hydrogen for transport, and batteries for temporary storage of electricity for short-time balances. First, the systems that compose the proposed plant are justified and described. Then a proposal for sizing these subsystems is given, based on using buoy-measured data at the expected location and simple mathematical models of the different sections of the plant. Finally the performance of the plant in a specific location is tested in detailed by using measured data, studying the influence of sizing on the expected performance."

The requirements of reverse osmosis, electrolysis and compression all fall within the capabilities of ceto.

Hydrogen production allows renewable energy to be stored and exported, something that would be highly desirable from my point of view.

Japan is indicating that they want hydrogen as an alternative to nuclear (for obvious reasons).

Offshore/off grid production of a transportable renewable fuel would have to be an attractive proposition for a renewable energy company.  I would imagine even the likes of Woodside and Exon would want to be part of that if it is viable.

Offshore and off grid removes the need to be located close to where the energy is consumed.  That opens up a whole lot of places that would otherwise not be considered.

As the bulk of hydrogen fuel would be transported by ship or pipeline, offshore rigs could be located just about anywhere there are waves.
