Abstract

The production of natural gas from sub-seafloor gas hydrates is one possible strategy to
meet the world’s growing demand for energy. On the other hand, climate warming scenarios
call for the substitution of fossil energy resources by sustainable energy concepts. Burning
natural gas from gas hydrates could be emission neutral if it was combined with a safe storage
of the emitted CO2. Laboratory experiments, that address corresponding strategies, need to be
performed under high pressures and low temperatures to meet the thermodynamic conditions
of the sub-seafloor environment. In this paper, we present a high-pressure flow-through
sample cell that is suitable for nuclear magnetic resonance (NMR) experiments at realistic
marine environmental conditions, i.e. pressures up to 15 MPa and temperatures from 5 to 20
°C, and we demonstrate its suitability in applied gas hydrate research.
