It is lossy _now_ and very expensive _now_. I think what the poster was saying was such barriers may be surmountable in time.

- gehsty 7y agoI work in subsea power cables, AC transmission is not efficient, HVDC transmission is efficient for long distances. India has HVDC links 1500km long. I don’t understand the ‘lossy’ description, any energy transfer loses energy, when dealing with utilities it is either acceptable or not. HVDC is proven long distance transmission technology. There is a subsea hvdc link in the early planning stage between Iceland and the U.K. I think it is more likely the financing of the project is not arranged yet than the technology. The cost of these links is generally cheaper than a new build power station of a similar capacity, so when you can transfer excess generation it becomes cost effective to build.
