干水在2.7 MPa和273.2 K下以水合物形式储存175 v（STP）/v甲烷，这接近能源部甲烷储存的体积目标。干水是二氧化硅稳定的自由流动的粉末（95%wt水），并且由于该材料的相对大的表面积与体积比，观察到快速的甲烷吸收（在160分钟内90%饱和吸收，没有混合）。
Dry water stores 175 v(STP)/v methane at 2.7 MPa and 273.2 K in a hydrate form which is close to the Department of Energy volumetric target for methane storage. Dry water is a silicastabilized free-flowing powder (95% wt water), and fast methane uptakes were observed (90% saturation uptake in 160 min With no mixing) as a result of the relatively large surface-to-volume ratio of this material.
