They don't have a glut - they have a lack of regasification terminals.
The LNG tankers going in circles waiting for a receiving terminal means that the ships aren't being used to move product.
Europe isn't the ONLY customer in the world - other countries need the LNG, and aren't getting it because they've been shut out of the market by the EuroWeeinies.

Run a LNG filled bare pipe through Munich during Oktoberfest and allow the celebrants to relieve themselves on the pipe. Just tell them not to step on the pipe. There is your fossil fuel-free,. practical heat source even Greta would approve.
