Offshore wind and hydrogen – Charley Rattan Associates

Source: www.charleyrattan.com

Floating Wind and Hydrogen.

At first sight, the proposition of the industrial-scale production of hydrogen – with all the challenges inherent in converting air to gas at sea, and all the hazards, difficulties and dangers of working in such a hostile environment – may appear fanciful.

However, there are good reasons why the combination of offshore wind with the production of hydrogen in the sea or at sea may be a very smart idea indeed.

One of the constraints for offshore wind has been the necessity for access to the electrical grid – but the move to hydrogen may remove this – so redefining the very nature of a wind farm. In addition, hydrogen production can utilise existing installations such as reusable gas or oil assets; for example, I am currently advising on the potential of incorporating an electrolyser into an oil and gas platform.

I hadn't thought of this-- offshore wind (particular the more efficient turbines in the deeper waters) definitely struggle with the grid connection problem, both the cost to put in a grid connection and the efficiency loss that comes from that power transportation process. But if hydrogen can instead be transported by pipeline then that flips the script. What'sthe ballpark comparison in how the relative costs and efficiencies of these two different pathways would take? Or are there too many variables and it really comes down to analyzing specific wind turbine sites and seeing which makes sense in that situation?

A slightly surprising take from a professional using hyperbolic language. One of course is a tried and tested bankable technology with scaleability, the other techmology, which the repondent cites, appear to be a research project and certainly not an investable proposition.

I'd like to support Matt. Hydrogen production using deep-sea hydroelectric power plants, such as Hydro Power Tower, which are still the only most powerful and independent sources of energy in the ocean, with it is possible to obtain electric energy in the industrial scale through the use of new submerged electric machines with permanent magnets that generate a large enough amount of electric energy to split hydrogen and oxygen. Such underwater power (100-200 MW) electrolyzers can supply hydrogen fuel not only to marine platforms, but also to unmanned ships. In addition, oxygen released during a chemical reaction can be used to clean up dead zones in the ocean. I sent a similar proposal to EC coll Horizon 2020 - "building a low-carbon, climate-resilient future: research and innovation in support of the European green agreement (H2020-LC-GD-2020)" and am currently looking for potential partners and a project coordinator. Therefore, if you want to participate in my project, I will be happy to invite you to contact me by email gsmprado@yandex.ru or call +79117074631. But here I agree with Charlie that this is just a Research project, but it was done at a high level of implementation. Now the task is to conduct tests on a scale of trl6, and then start developing technical documentation for the production of a pilot batch of 100 MW electrolyzers.

Thank Charley for the Post!
