연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

초록

An apparatus and system is described for storing high-pressure fluids such as hydrogen. An inner tank and pre-stressed concrete pressure vessel share the structural and/or pressure load on the inner tank. The system and apparatus provide a high performance and low cost container while mitigating hydrogen embrittlement of the metal tank. System is useful for distributing hydrogen to a power grid or to a vehicle refueling station.

1. An apparatus for bulk storage of high-pressure hydrogen gas comprising: a plurality of multi-layered tanks adapted to hold the high-pressure hydrogen gas for selective discharge through a distribution unit, each of the plurality of multi-layered tanks including an inner layer and an outer layer each being a metal material, wherein said inner layer is nested within said outer layer, and wherein said inner layer is resistant to hydrogen embrittlement and permits the transfer of hydrogen gas therethrough for venting from said multi-layered tank;a pre-stressed concrete pressure vessel disposed around said plurality of multi-layered tanks and entirely enclosing said plurality of multi-layered tanks except through said distribution unit, said pre-stressed concrete pressure vessel adapted to provide at least a portion of structural support for said plurality of multi-layered tanks,wherein the high-pressure hydrogen gas exerts a cylinder stress on each of said plurality of multi-layered tanks, each of said plurality of multi-layered tanks being adapted to carry a first portion of the cylinder stress and said pre-stressed concrete pressure vessel being adapted to carry a second portion of the cylinder stress, wherein, for each of said plurality of multi-layered tanks, the first portion of the cylinder stress as carried by said multi-layered tank is a substantial portion of the cylinder stress including up to 50% of the cylinder stress, and wherein the second portion of the cylinder stress as carried by said pre-stressed concrete pressure vessel is a substantial portion of the cylinder stress including at least 50% of the cylinder stress. 2. The apparatus as recited in claim 1 further comprising one or more steel tendons within said pre-stressed concrete pressure vessel. 3. The apparatus as recited in claim 1 further comprising a manifold which is also fluidly coupled to said distribution unit. 4. The apparatus as recited in claim 1 wherein said inner and outer layers of said plurality of multi-layered tanks are made of a steel material. 5. The apparatus of claim 4 further comprising an interface material disposed between an outermost layer of each of said plurality of multi-layered tanks and said pre-stressed concrete vessel. 6. The apparatus of claim 5 wherein said interface material is concrete with high strength and high ductile properties. 7. A composite storage container for pressurized hydrogen gas, comprising: a plurality of multi-layered storage tanks for holding the pressurized hydrogen gas;a pre-stressed concrete pressure vessel disposed around said plurality of multi-layered storage tanks, said pre-stressed concrete pressure vessel adapted to support at least a portion of a pressure load to said plurality of multi-layered storage tanks, wherein the pressurized hydrogen gas exerts a cylinder stress, each of said plurality of multi-layered storage tanks being adapted to carry a first portion of the cylinder stress and said pre-stressed concrete pressure vessel being adapted to carry a second portion of the cylinder stress, wherein, for each of said plurality of multi-layered tanks, the first portion of the cylinder stress as carried by said multi-layered storage tank is a substantial portion of the cylinder stress including up to 50% of the cylinder stress, and wherein the second portion of the cylinder stress as carried by said pre-stressed concrete pressure vessel is a substantial portion of the cylinder stress including at least 50% of the cylinder stress; anda charge/discharge tank fluidly coupled to said plurality of multi-layered storage tanks;wherein each of said plurality of multi-layered storage tanks has multiple layers including an inner layer and an outer layer each being a metal material, wherein said inner layer is nested within said outer layer, wherein said inner layer is resistant to hydrogen embrittlement and permits the transfer of hydrogen gas therethrough for venting from said plurality of multi-layered storage tanks, and wherein said pre-stressed concrete pressure vessel entirely encloses said plurality of multi-layered tanks except through said charge/discharge tank. 8. The container of claim 7 further comprising one or more sensors within the container adapted to monitor one or more characteristic of the container. 9. The container of claim 8 wherein said monitored characteristic is at least one of temperature, pressure or fluid detection. 10. A hydrogen charging/discharging system comprising: a storage container for high-pressure hydrogen gas comprising: a plurality of multi-layered tanks adapted to contain the hydrogen gas, each of said plurality of multi-layered tanks including an innermost layer nested within an outer layer each being a metal material, wherein said inner layer is adapted to permit the transfer of hydrogen gas therethrough for venting from each of said plurality of multi-layered tanks;a pre-stressed concrete pressure vessel disposed around each of said plurality of multi-layered tanks, wherein said pre-stressed concrete pressure vessel and said plurality of multi-layered tanks share support of a pressure load on said tank, wherein, for each of said plurality of multi-layered tanks, said multi-layered tank carries a first portion of the pressure load and said pre-stressed concrete pressure vessel carries a second portion of the pressure load, wherein the first portion of the pressure load as carried by said multi-layered tank is a substantial portion of the pressure load including up to 50% of the pressure load, and wherein the second portion of the pressure load as carried by said pre-stressed concrete pressure vessel is a substantial portion of the pressure load including at least 50% of the pressure load; anda distribution unit adapted to direct the hydrogen gas into and out of said plurality of multi-layered tanks, wherein said pre-stressed concrete pressure vessel surrounds said plurality of multi-layered tanks and wherein the hydrogen gas is released through said distribution unit. 11. The system of claim 10 wherein said distribution unit includes an inlet and an outlet to each of said plurality of multi-layered tanks. 12. The system of claim 11 further comprising an interface material disposed between an outermost layer of each of said plurality of multi-layered tanks and said pre-stressed concrete vessel wherein said interface material is concrete with high strength and high ductile properties. 13. The system of claim 10 wherein said storage container further comprises an inlet and an outlet for the hydrogen in communication with said distribution unit; and wherein said inlet is adapted to receive the hydrogen from a hydrogen generator and said outlet is adapted to provide the hydrogen to a power distribution grid. 14. The system of claim 10 wherein said storage container further comprises an inlet and an outlet for the hydrogen in communication with said distribution unit; and wherein said inlet is adapted to receive the hydrogen from a hydrogen transporter and said outlet is adapted to provide the hydrogen to a vehicle fueling station.
