You can convert electricity, water and CO2 to fuels, such as hydrogen and natgas. These fuels can then be transported.

There are significant energy losses if all you want on the other end is electricity. But not so bad if you're burning it for heat.

In theory a nuclear reactor could produce both electricity and heat to produce synthetic fuels, making it more cost effective than renewables.

For electricity only it looks like renewables are significantly cheaper however.
