| Summary: | <p>This paper deals with a new concept for the conversion of far-offshore
wind energy into sustainable fuel. It relies on autonomously sailing
energy ships and manned support tankers. Energy ships are
wind-propelled. They generate electricity using water turbines
attached underneath their hull. Since energy ships are not
grid-connected, they include onboard power-to-X plants for storage of
the produced energy. In the present work, the energy vector is
methanol.</p>
<p>The aim of the paper is to propose an energy ship design and to
provide an estimate for its energy performance as function of the wind
conditions. The energy performance assessment is based on a numerical
model which is described in the paper. Results show that the wind
energy-to-methanol (chemical energy) conversion efficiency is 24 %
and that such an energy ship deployed in the North Atlantic Ocean could
produce approximately 5 <span class="inline-formula">GWh</span> per annum of chemical energy
(900 <span class="inline-formula">t</span> of methanol per annum).</p> |
