Very Interesting in the suggestion it proposes to capture dissolved CO2 from seawater.
Interesting in that it does not have all the technology necessary for the solution to be implemented.
Interesting that a similar conversion process to produce methanol from atmospheric captured CO2 is much closer to technical completion and development?
Very very interesting that the prospect of the solution provides one more reason to keep things just the way they are. IE keep on burning fossil fuels because one day we will have a solution to keep everything (ICE vehicle industry) just as it is. No Change!
(Excuse the Cynicism. It is worth pointing out that while a prospect that may be a step in a lower carbon future, such projects also offer an excuse to put off action applying solutions we can access now.)
The most interesting of all aspects is the energy conversion or efficiency balance. The project accepts there currently is no large scale commercial solution for extracting CO2 from seawater or certainty on how to manage the byproducts such as chlorine. Hence the economics, scale and overall conversion efficiency of the technology are all speculative. The end point is a floating production facility that can deliver 1.7t of product per hour. It is assumed this figure only applies when the sun shines.
This is not all that significant an output, given the world consumed approx 4,600 million tonnes of oil in 2017. Approx 70% of this goes into producing light and medium weight distillates. IE mostly diesel, petrol, aviation and domestic heating fuel (kero).
It would be very very interesting if the report was able to present a comparison with more direct alternatives for the use of collected solar energy in battery or direct hydrogen powered systems. The proposed technology creates hydrogen as a primary step, and hydrogen used in a fuel cell is 3-4 times more energy efficient than methanol used as a vehicle fuel. It would seem much more effective to export the captured solar energy as hydrogen directly than export it as a heavier and less effective carbon based fuel?
For anyone with a love of statistics, data or suffering insomnia, the following may prove useful.
