Description

부유식 수소 생산 및 관리시스템{HYDROGEN-FLOATING PRODUCTION AND TREATMENT SYSTEM}Floating hydrogen production and management system {HYDROGEN-FLOATING PRODUCTION AND TREATMENT SYSTEM}

본 발명은 부유식 수소 생산 및 관리시스템에 관한 것으로서, 더욱 상세하게는 수소를 안정적으로 생산 및 공급할 수 있는 부유식 수소 생산 및 관리시스템에 관한 것이다.The present invention relates to a floating hydrogen production and management system, and more particularly, to a floating hydrogen production and management system capable of stably producing and supplying hydrogen.

오늘날 환경문제가 인류의 주요한 이슈로 대두됨에 따라, 전 세계적으로 지구 온난화 문제 해결 및 대기환경 개선을 위해 노력하고 있다. 이러한 문제 해결을 위해 환경문제의 근원이 되는 화석에너지를 대신하여 태양광, 풍력, 조력 및 수력과 같은 재생에너지에 대한 관심이 높아지고 있다.As environmental problems are emerging as a major issue for mankind today, efforts are being made to solve global warming problems and improve the atmospheric environment around the world. In order to solve this problem, interest in renewable energy such as solar power, wind power, tidal power and hydro power is increasing instead of fossil energy, which is the source of environmental problems.

그러나 재생에너지는 지역별, 계절별 수급 불균형의 문제가 있는 바, 재생에너지로 생산된 에너지를 효과적으로 저장할 수 있는 에너지 저장매체, 다시 말해 에너지 캐리어(Energy-carrier)가 필요하다. 다양한 에너지 저장매체 중에서 대용량, 장기간 안정적으로 저장할 수 있으면서도, 타 에너지원으로의 변환이 용이한 수소가 최적의 에너지 캐리어 각광받고 있다. However, since renewable energy has a problem of regional and seasonal imbalance in supply and demand, an energy storage medium that can effectively store energy produced by renewable energy, that is, an energy-carrier is required. Among various energy storage media, hydrogen, which can be stored stably in a large capacity and for a long period of time, and is easy to convert into other energy sources, is in the spotlight as an optimal energy carrier.

수소가 미래의 주요한 에너지원으로 주목받음에 따라, 수소의 저장 및 운송 기술에 관련된 과제들이 제시되고 있다. 수소의 저장방법으로는 기체나 액체 등 다양한 형태로 구현할 수 있겠으나, 에너지 밀도, 저장량 및 수송 효율 등을 고려할 때 액화수소의 형태로 저장하는 것이 유리한 것으로 인식되고 있다. 그러나 액화수소는 끓는 점이 약 -253 ℃인 초저온의 유체이고, 비중은 액화천연가스(LNG, Liquefied Natural Gas)의 약 1/6 수준으로 작아 체적당 증발률(BOR, Boil-Off Rate)이 액화천연가스의 약 10배에 달할 정도로 높다. 따라서 수소의 생산, 저장 및 취급을 안정적이고 효율적으로 수행할 수 있는 방안이 요구된다.As hydrogen draws attention as a major energy source in the future, challenges related to hydrogen storage and transportation technology are presented. As a storage method of hydrogen, it can be implemented in various forms such as gas or liquid, but it is recognized that storage in the form of liquid hydrogen is advantageous in consideration of energy density, storage amount, and transport efficiency. However, liquefied hydrogen is an ultra-low temperature fluid with a boiling point of about -253 ℃, and its specific gravity is about 1/6 of that of liquefied natural gas (LNG), so the evaporation rate per volume (BOR, Boil-Off Rate) is liquefied. It is about ten times higher than that of natural gas. Therefore, there is a need for a method capable of stably and efficiently performing hydrogen production, storage and handling.

한편, 수소는 석유화학이나 제철 등 화학공정의 부산물로 발생되는 부생가스에서 수소를 추출하거나, 천연가스 또는 갈탄 등 1차 에너지로부터 개질하여 생산할 수도 있으며, 물을 전기분해하여 수소를 생산하는 등 다양한 방법에 의해 생산이 가능하다는 이점이 있다. 다만, 개질을 통해 수소를 생산하는 경우 대기 환경에 중대한 영향을 미치는 이산화탄소가 부산물로 발생된다는 단점이 있다. On the other hand, hydrogen can be produced by extracting hydrogen from by-product gas generated as a by-product of chemical processes such as petrochemical or steelmaking, or by reforming from primary energy such as natural gas or lignite, and can be produced by electrolysis of water to produce hydrogen. There is an advantage that production is possible by the method. However, when hydrogen is produced through reforming, there is a disadvantage in that carbon dioxide, which has a significant effect on the atmospheric environment, is generated as a by-product.

However, the present invention is not limited thereto, and as long as it can provide and supply power to the water electrolyzer 110 to be described later, it may include wind power generators of various shapes and structures, such as floating turbines installed on the ground or connected to the ground by wire. .

The distribution device 120 applies the power required for the operation of the water electrolyzer 110 to the water electrolyzer 110 side, and the remaining power is supplied to the power demander 10 on land, so that the wind power generator (1) It is possible to efficiently utilize the power produced by The distribution device 120 may be implemented as a plurality of switches or may be provided with a power distributor to distribute power.

변압기(160)는 분배장치(120)와 수전해장치(110)에 각각 전기적으로 연결되어 분배장치(120)에 의해 분배되어 전달되는 전원 또는 전력을 공급받아 수전해장치(110)의 작동에 적합하도록 전압을 조정될 수 있다. 변압기(160)에 의해 전압이 조정된 전원은 직류-교류 변환기(170)로 출력될 수 있으며, 직류-교류 변환기(170)는 풍력발전기(1)로부터 제공되는 직류 발전전원을 입력받아, 전압 또는 전력을 필요로 하는 수전해장치(110)의 요구 조건을 고려하여 교류 발전전원으로 변환하여 전달함으로써 후술하는 수전해장치(110)의 안정적인 작동을 도모할 수 있다.The transformer 160 is electrically connected to the distribution device 120 and the water electrolysis device 110 , respectively, and receives power or power distributed and transmitted by the distribution device 120 , and is suitable for the operation of the water electrolysis device 110 . The voltage can be adjusted to The power whose voltage is adjusted by the transformer 160 may be output to the DC-AC converter 170 , and the DC-AC converter 170 receives the DC power generated from the wind power generator 1 and receives a voltage or The stable operation of the water electrolyzer 110, which will be described later, can be achieved by converting the power to AC power generation in consideration of the requirements of the water electrolyzer 110 requiring power.

수전해장치(110)는 부유식 해상 구조물에 탑재되어 후술하는 담수화장치(150)로부터 제공되는 물을 공급받음과 동시에, 풍력발전기(1)가 생산한 전원 또는 전기를 공급받아 작동할 수 있다. 수전해장치(110)는 전력이 인가되면, 공급받은 물을 전기분해하여 산소와 수소를 분리함으로써, 수소가스를 생산할 수 있다. 수전해장치(110)는 알칼리 전해조 방식이나 고분자 이온 교환막 방식 또는 고체 산화물 방식으로 마련될 수 있으나, 어느 하나에 한정되는 것은 아니다. 수전해장치(110)의 작동원리 및 작동방식은 이미 공지된 기술에 해당하므로 자세한 설명은 생략한다.The water electrolyzer 110 is mounted on a floating offshore structure and is supplied with water provided from a desalination device 150 to be described later, and can be operated by receiving power or electricity produced by the wind power generator 1 . When electric power is applied, the water electrolyzer 110 may produce hydrogen gas by electrolyzing the supplied water to separate oxygen and hydrogen. The water electrolyzer 110 may be provided in an alkaline electrolytic cell method, a polymer ion exchange membrane method, or a solid oxide method, but is not limited thereto. Since the operating principle and operating method of the water electrolyzer 110 correspond to known techniques, a detailed description thereof will be omitted.

When the water electrolyzer 110 directly electrolyzes seawater to produce hydrogen gas, the seawater contains a large amount of impurities such as sodium, so the production efficiency of hydrogen gas through the water electrolysis reaction is very low. Accordingly, the desalination device 150 may desalinate seawater to increase the hydrogen gas production efficiency of the water electrolyzer 110 and supply it to the water electrolysis device 110 . The desalination device 150 may receive seawater from a seawater pump, and although not shown in the drawing, may include a heating device for heating seawater, a condenser for condensing water vapor generated by heating, etc. Fresh water may be obtained by cooling, and this may be provided to the water electrolyzer 110 .

압축부(131)는 수소 액화라인(130)으로 유입되는 수소가스를 가압하도록 마련된다. 압축부(131)는 수소가스의 재액화효율을 향상시키기 위해 수소가스를 가압하여 후술하는 냉각부로 공급할 수 있다. 압축부(131)는 컴프레서를 포함할 수 있으며, 도 1에서는 컴프레서가 단일로 배치된 것으로 도시되어 있으나, 이는 일 예로서 수소가스의 가압 압력범위에 따라 다단 컴프레서로 이루어질 수도 있다. The compression unit 131 is provided to pressurize the hydrogen gas flowing into the hydrogen liquefaction line 130 . The compression unit 131 may pressurize hydrogen gas to improve the reliquefaction efficiency of hydrogen gas and supply it to a cooling unit to be described later. The compression unit 131 may include a compressor, and although the compressor is shown as a single arrangement in FIG. 1 , it may be formed of a multi-stage compressor depending on the pressurized pressure range of hydrogen gas as an example.

수소 액화라인(130) 상의 제1 열교환기(132)로 진입하는 가압된 수소가스는 압축부(131)에 의해 가압되면서 온도 역시 상승한 상태이므로 수소 액화라인(130) 상의 제2 열교환기(133)로 진입하는 수소가스보다 상대적으로 온도가 높다. 또한, 냉매순환라인(180) 상의 제1 열교환기(132)로 진입하는 냉매는 전단에서 제2 열교환기(133)를 거치면서 냉열을 제공한 상태이므로 상대적으로 온도가 높으나, 압축부(131)를 통과한 고온의 수소 증발가스 보다는 온도가 훨씬 낮으므로 냉열을 제공하기에 충분하다. 따라서, 제1 열교환기(132)에서는 제2 열교환기(133) 대비 상대적으로 높은 온도범위에서 열교환이 이루어지되, 수소 액화라인(130) 상의 가압된 수소가스와 냉매순환라인(180) 상의 가열된 냉매가 서로 열교환함으로써, 수소 액화라인(130) 상의 수소가스가 1차적으로 냉각될 수 있다. Since the pressurized hydrogen gas entering the first heat exchanger 132 on the hydrogen liquefaction line 130 is pressurized by the compression unit 131 and the temperature is also increased, the second heat exchanger 133 on the hydrogen liquefaction line 130 . The temperature is relatively higher than the hydrogen gas entering the furnace. In addition, the refrigerant entering the first heat exchanger 132 on the refrigerant circulation line 180 is in a state in which cooling heat is provided while passing through the second heat exchanger 133 at the front end, so the temperature is relatively high, but the compression unit 131 The temperature is much lower than the high-temperature hydrogen boil-off gas that has passed through, so it is sufficient to provide cooling heat. Accordingly, in the first heat exchanger 132 , heat exchange is performed in a relatively high temperature range compared to the second heat exchanger 133 , the pressurized hydrogen gas on the hydrogen liquefaction line 130 and the heated on the refrigerant circulation line 180 . As the refrigerants exchange heat with each other, the hydrogen gas on the hydrogen liquefaction line 130 may be primarily cooled.

아울러, 후술하는 기액분리기(135)에서 분리된 미액화수소는 팽창부(134)를 거치면서 수소의 액화점에 근접하게 냉각된 상태이므로, 제2 열교환기(133)에서는 극저온의 냉매와 더불어, 미액화수소의 냉열을 수소가스로 추가적으로 전달함으로써, 수소가스의 액화효율을 증대시킬 수 있다. 또한, 후술하는 저장탱크(190)에서 발생되는 수소 증발가스 역시 수소 액화라인(130) 상의 제1 열교환기(132)를 거쳐 1차적으로 냉각된 수소가스보다 온도가 낮으므로, 후술하는 증발가스 공급라인(191)이 저장탱크(190)의 수소 증발가스를 미액화수소로 합류시켜 제2 열교환기(133)로 공급함으로써, 제2 열교환기(133)의 냉각 효율 및 수소가스의 액화효율을 최대화할 수 있다.In addition, since the unliquefied hydrogen separated in the gas-liquid separator 135 to be described later is cooled close to the liquefaction point of hydrogen while passing through the expansion unit 134, in the second heat exchanger 133, together with the cryogenic refrigerant, By additionally transferring the cooling heat of unliquefied hydrogen to hydrogen gas, it is possible to increase the liquefaction efficiency of hydrogen gas. In addition, since the hydrogen boil-off gas generated in the storage tank 190 to be described later also has a lower temperature than the hydrogen gas primarily cooled through the first heat exchanger 132 on the hydrogen liquefaction line 130, the boil-off gas supply to be described later Line 191 merges the hydrogen boil-off gas of the storage tank 190 into non-liquefied hydrogen and supplies it to the second heat exchanger 133, thereby maximizing the cooling efficiency of the second heat exchanger 133 and the liquefaction efficiency of hydrogen gas can do.
