Sea Energy Harvesting – off-shore

Of course, onshore resources are first.

Of course, it will take a long time before it’s real business, but we can start with the vision…

Where is the most “energy intense” location on earth in terms of wind, solar and other renewable sources? Is it onshore or off-shore?

Let’s see what sea energy harvesting is about…

There was in 2011 an interesting research I recommend here, that overlapped the irradiation and the temperature, in order to determine where solar can yield more, given the PV panels are less efficient the higher the temperature. The resulting optimal areas for generation where the Himalayas (not too accessible), the Antarctica (similar to off-shore) and regions in the southern Andes.

Do we need batteries without wheels?

Let’s start this post by quoting another post on a recent market estimation by IMS research, estimating the battery energy storage is to skyrocket up 200 M$ today to 19 bn$ in 2017.

While this may look promising, and seem the perfect way to increase renewable penetration, paving the way to a decarbonized energy sector, please stop. …and reconsider if it is the best solution.

Why decarbonize the power sector alone… if we can decarbonize the transportation and the power sector at the same time?

Battery wheels

How? Investment in electric vehicles (EVs) must be economically efficient in itself (cheaper than the CO2 emmitting vehicles) so every € invested has already a return via mobility (for the owner/user). This means using the available storage is relatively “free” to the power sector. In my opinion, subsidizing  battery storage (gathering dust inside a building) is a stupid idea compared to incentivizing the “transport-sector-decarbonizing-storage” or, to say it other way, batteries-with-wheels. EVs should be incentivized not only by governments trying to reduce the energy sector trade unbalances and reducing CO2 emissions, but also by utilities willing to increase the customer’s bill (an EV customer is billed aprox. a 30% more)
