Description

本発明は、エネルギーシステムに関し、特に、再生可能エネルギーを利用したエネルギーシステムに関する。  The present invention relates to an energy system, and more particularly, to an energy system using renewable energy.

再生可能エネルギーは、バイオマス燃料、バイオマス由来の廃棄物により製造された燃料、バイオマス由来の熱などの他に、いったんは電気に変化されて取り出される大規模水力発電、中小水力発電、太陽光発電、風力発電、地熱発電、波力発電、海洋温度差発電など、多くの自然エネルギーがある。従来、この再生可能エネルギー由来の電気は、電力会社に売却されるか、その場で電解式水素製造装置により水素・酸素への変換が行なわれている。  Renewable energy includes biomass fuel, fuel produced from biomass-derived waste, heat derived from biomass, etc., as well as large-scale hydropower, small and medium hydropower, solar power, There are many natural energies such as wind power generation, geothermal power generation, wave power generation, and ocean thermal power generation. Conventionally, electricity derived from this renewable energy is sold to an electric power company or converted into hydrogen / oxygen on the spot by an electrolytic hydrogen production apparatus.

水素は、同じ二次エネルギーである電力に比べて、貯蔵性の点では決定的な優位性を持っている。気候や季節に依存し、出力のコントロールが困難な自然エネルギーが多くをしめる再生可能エネルギーを有効に利用するうえで、水素のこの利点はきわめて重要である。  Hydrogen has a decisive advantage in terms of storability compared to electric power, which is the same secondary energy. This advantage of hydrogen is extremely important for the effective use of renewable energy, which depends on the climate and the seasons, and the amount of renewable energy is difficult to control.

しかし、水素を二次エネルギーとして利用するとき、特に自然エネルギーを利用して水素を製造する場合には、自然エネルギーを得る場所が、奥深い山中、風の強い海岸など、水素の多くを消費する都会とは離れていることが多い。これらの場所は、水素の輸送インフラであるパイプラインや水素の液化輸送の機器の普及など輸送手段が未熟であることから、再生可能エネルギーの開発が進まないという課題があった。また、開発が進まないことにより輸送手段が未熟のままであるという悪循環となっている。  However, when using hydrogen as secondary energy, especially when producing hydrogen using natural energy, the place where natural energy is obtained is a city that consumes a lot of hydrogen, such as deep in the mountains and windy beaches. Is often far away. In these places, there is a problem that the development of renewable energy does not progress because the transportation means such as the pipeline of hydrogen transportation infrastructure and the spread of equipment for liquefying and transporting hydrogen are immature. Moreover, it is a vicious circle that transportation means remain immature due to the lack of development.

さらに、現在風力や中小水力などで発電された電気は、電力会社に売電されているが、電力会社への買い取り相場は低く発電コストとの採算性が悪いという課題がある。  Furthermore, electricity generated by wind power or small and medium hydropower is currently sold to power companies, but there is a problem that the market price to power companies is low and the profitability with power generation costs is poor.

本発明はこうした状況に鑑みてなされたものであり、その目的は、再生可能エネルギーを効率良く利用する技術の提供にある。  The present invention has been made in view of such circumstances, and an object thereof is to provide a technique for efficiently using renewable energy.

You may provide the adjustment part which adjusts transfer time.

図１は、本発明の実施の形態に係るエネルギーシステムの構成を示す。エネルギーシステム１０は、再生可能エネルギーにより発電し、発電された電気を近傍の電力会社の送電ネットワーク２０から託送する複数の発電システム２１〜２７と、送電ネットワーク２０に接続され、発電システム２１〜２７から託送された電気を受け取って、受け取った電気により水素、又は水素及び酸素を製造する電解式水素製造装置２８と、電解式水素製造装置２８から製造された水素を受け取って、受け取った水素を利用する水素利用者装置２９と、エネルギーシステム全体を管理する管理システム４０を備える。  FIG. 1 shows a configuration of an energy system according to an embodiment of the present invention. The energy system 10 is generated by renewable energy, and is connected to the power transmission network 20 and a plurality of power generation systems 21 to 27 that consign the generated electricity from the power transmission network 20 of a nearby power company. Receiving the consigned electricity, producing hydrogen or hydrogen and oxygen by the received electricity, and receiving the hydrogen produced from the electrolytic hydrogen production device 28 and using the received hydrogen A hydrogen user device 29 and a management system 40 for managing the entire energy system are provided.

複数の発電システムは、太陽光発電システム２１、既存ダム未利用水力発電システム２２、地熱発電システム２３、バイオマス発電システム２４、中小水力発電システム２５、風力発電システム２６、及び波力発電システム２７を含む。既存ダム未利用水力発電システム２２又は中小水力発電システム２５は、例えば、既存ダムの発電用水利以外の農業用水、工業用水道用水、上水道用水、かんがい用水、洪水調節・農地防災用水、消流雪用水、河川維持用水、不特定用水、レクリエーション用水から選ばれた一つ又は複数の任意の組み合わせを利用して発電を行う。  The plurality of power generation systems include a solar power generation system 21, an existing dam-unutilized hydroelectric power generation system 22, a geothermal power generation system 23, a biomass power generation system 24, a small and medium hydropower generation system 25, a wind power generation system 26, and a wave power generation system 27. . The existing dam unused hydroelectric power generation system 22 or the small / medium hydroelectric power generation system 25 is, for example, agricultural water other than power generation water for existing dams, industrial water, water supply, irrigation water, flood control / farmland disaster prevention water, extinguishing snow Electricity is generated using one or more arbitrary combinations selected from water, river maintenance water, unspecified water, and recreational water.

複数の発電システム２１〜２７は、通信ネットワークの一例であるインターネット３０に接続されており、インターネット３０を介して、管理システム４０との間でデータを送受信する。  The plurality of power generation systems 21 to 27 are connected to the Internet 30 which is an example of a communication network, and transmit and receive data to and from the management system 40 via the Internet 30.

本実施の形態のエネルギーシステム１０では、点在する発電システム２１〜２７において再生可能エネルギーにより発電された電気を、送電ネットワーク２０により託送し、水素需要地域に電解式水素製造装置２８を設けて、送電ネットワーク２０から受け取った電気で水素を製造し、需要者に販売する。  In the energy system 10 of the present embodiment, electricity generated by renewable energy in the scattered power generation systems 21 to 27 is transferred by the power transmission network 20, and an electrolytic hydrogen production apparatus 28 is provided in the hydrogen demand area. Hydrogen is produced by electricity received from the power transmission network 20 and sold to consumers.

再生可能エネルギーは、地球温暖化効果ガスをほとんど排出しない理想的なエネルギーであるが、ダムの発電未利用水、自流水、中小河川発電、風力、上水道ライン、下水放流口などは全国に点在する。これらは、大規模なものから多くの小規模なものまで存在しており、それぞれ丁寧に開発していく必要がある。一方で、温暖化効果ガスの排出の削減に向けて、国、地方自治体、大企業を中心に、再生可能エネルギーの使用比率を高めていく必要があり、再生可能エネルギーの需要は拡大する。従来のように、再生可能エネルギーが得られる場所で水素を製造すると、それぞれの場所で水素の製造、貯蔵、及び輸送のための設備投資が必要であり、さらに輸送されてきた様々な量の水素を購入者の必要量にまとめて再輸送する設備も必要となるので、ここにも設備投資が必要であった。  Renewable energy is ideal energy that emits almost no global warming effect gas, but dam power generation unused water, free flowing water, small and medium river power generation, wind power, water supply lines, sewage outlets, etc. are scattered throughout the country. To do. These exist from large-scale to many small-scale ones, and each must be carefully developed. On the other hand, in order to reduce greenhouse gas emissions, it is necessary to increase the use ratio of renewable energy, mainly by the national government, local governments, and large companies, and the demand for renewable energy will increase. Conventionally, when hydrogen is produced at a place where renewable energy can be obtained, capital investment for production, storage, and transportation of hydrogen is required at each place, and various amounts of hydrogen that have been transported are also required. Because it is also necessary to have equipment that can be transported together in the amount required by the purchaser, capital investment was also necessary here.

本実施の形態のエネルギーシステム１０によれば、それぞれの場所での水素の製造設備と貯蔵と輸送のための設備投資が不要となる。また、需要の高い地域に大型の電解式水素製造装置２８を設置して水素製造を行えば、需要地域における水素インフラの整備を最小限に抑え、エネルギーシステム１０全体の設備投資を大幅に少なくすることができる。また、水素の輸送手段が整備されていない、山中や海岸などの不便な場所の再生可能エネルギーであっても、電気の形態で、ほぼ全国を網羅している送電ネットワークにより容易に都市部へ託送して利用することができるので、貴重で重要なクリーンエネルギー資源を増大させ、拡大する需要に応えることができる。また、発電システムの管理事業者からみても、再生可能エネルギーを、低い買い取り相場で電力会社に売電されるのではなく、付加価値の最も高い水素や酸素に変換して売ることができるので、採算性が良くなるというメリットがある。  According to the energy system 10 of the present embodiment, there is no need for hydrogen production facilities and capital investment for storage and transportation at each location. In addition, if hydrogen is produced by installing a large electrolytic hydrogen production device 28 in a high demand area, the maintenance of the hydrogen infrastructure in the demand area is minimized, and the capital investment of the entire energy system 10 is greatly reduced. be able to. In addition, even renewable energy in inconvenient places such as in the mountains or on the shore, where hydrogen transportation means are not established, can be easily transferred to urban areas in the form of electricity through a power transmission network that covers almost the whole country. As a result, it is possible to increase valuable and important clean energy resources and meet the expanding demand. Also, from the viewpoint of the power generation system management company, renewable energy can be sold by converting it to hydrogen or oxygen with the highest added value, rather than being sold to electric power companies at low purchase prices. There is an advantage that profitability is improved.

A consignment cost management unit 52 for management and a charging database 53 for storing charging information are provided. The hydrogen selling price management unit 51 and the consignment cost management unit 52 calculate the value to be given to the manager of each device and the cost to be paid by the manager of each device, and record them in the charging database 53. When producing hydrogen or hydrogen and oxygen, the electrolytic hydrogen production apparatus 28 may receive more electricity from the power transmission network 20 if only the electricity commissioned from the power generation system is insufficient. In this case, the billing server 50 acquires the amount of electricity further received by the electrolytic hydrogen production apparatus 28 and performs a process of charging the price of the charge to the administrator of the electrolytic hydrogen production apparatus 28. Thereby, the billing information of the business operator and the user involved in the energy system 10 can be managed in an integrated manner.
