Description
本願は、2021年9月16日に日本国特許庁に出願された特願2021-151135号に基づき優先権を主張し、その内容をここに援用する。
<水素供給システム及び水素消費プラントの構成>
図1に示されるように、本開示の実施形態1に係る水素消費プラント1は、水素を任意の目的で消費する水素消費装置2と、水素消費装置2に水素を供給する水素供給システム10とを備えている。水素消費装置2については特に限定はしないが、例えば、水素のみを燃料とする、又は、他の燃料に対して水素を混入した燃料を使用するガスタービン3とすることができ、実施形態1では、水素消費装置2を、他の燃料に対して水素を混入した燃料を使用するガスタービン3として説明する。水素消費装置2がガスタービン3の場合、ガスタービン3の燃焼器3aには、燃料(例えば天然ガス)と、水素供給システム10からの水素とが供給されるようになっている。図1には、燃料と水素とが別々に燃焼器3aに供給されるように描かれているが、燃料と水素とが混合された後に燃焼器3aに供給されるようにしてもよい。
次に、本開示の実施形態1に係る水素供給システム10及び水素消費プラント1の動作について説明する。水素消費プラント1では、水素供給システム10から水素が水素流通ライン12を介してガスタービン3の燃焼器3aに供給される。燃焼器3aに供給された水素は、燃焼器3aに供給された燃料と共に、圧縮機3bから供給された圧縮空気によって燃焼される。すなわち、水素がガスタービン3の燃焼器3aで消費される。燃焼器3aにおける燃焼により生じた排ガスでタービン3cを駆動することによって、ガスタービン3が駆動する。
図1には、1つの貯蔵タンク15が設けられているように描かれているが、2つ以上の貯蔵タンク15が設けられていてもよい。この場合、複数の貯蔵タンク15をバイパスライン14に並列に設けて、それぞれの貯蔵タンク15に同時に水素を貯蔵させてもよい。貯蔵タンク15から水素を供給する場合には、それぞれの貯蔵タンク15から同時に水素を供給してもよいし、1つの貯蔵タンク15から水素を供給し、その貯蔵タンク15が空になったら別の貯蔵タンク15から水素を供給するようにしてもよい。また、複数の貯蔵タンクのそれぞれにバイパスラインを連通させる切替装置を設けて、それぞれの貯蔵タンク15に別々に水素を貯蔵させてもよい。
次に、実施形態2に係る水素供給システム及び水素消費プラントについて説明する。実施形態2に係る水素供給システム及び水素消費プラントは、実施形態1に対して、貯蔵タンク15の構成を変更したものである。尚、実施形態2において、実施形態1の構成要件と同じものは同じ参照符号を付し、その詳細な説明は省略する。
図2に示されるように、本開示の実施形態2に係る水素供給システム10において、バイパスライン14には、貯蔵タンク15と、貯蔵タンク15の下流側に位置する圧縮機17と、貯蔵タンク15の上流側に位置する流量制御弁21とが設けられている。実施形態2における貯蔵タンク15は、バッファータンク13よりも低圧の条件下において水素を貯蔵するものである。低圧条件下でガスを貯蔵することから、タンク1基当たりの大型化及び設置基数の低減が可能であり、又、タンク本体を安価な構造とすることが出来る。これにより、貯蔵のために必要な設備費を総合的に低く抑えることができる。
本開示の実施形態2に係る水素供給システム10において、水素の需要量の変動が小さい場合にバッファータンク13の緩衝機能によってその変動を吸収させつつ負荷追従させる動作については、実施形態1と同じである。水素の需要量の変動が大きい場合に水素の供給量を燃料の供給量の変動に追従させる実施形態2の動作が実施形態1とは異なるので、以下ではこの動作についてのみ説明する。
実施形態2においても、図2には、1つの貯蔵タンク15が設けられているように描かれているが、実施形態1の変形例と同様に、2つ以上の貯蔵タンク15が設けられていてもよい。実施形態2において複数の貯蔵タンク15が設けられている場合の各貯蔵タンク15への水素の貯蔵及び各貯蔵タンク15からの水素の供給の運用方法については、実施形態1の変形例と同じである。
実施形態1及び2では、バッファータンク13の設計圧力と貯蔵タンク15の設計圧力とは異なっていたが、バッファータンク13と貯蔵タンク15とを同じ設計圧力にしてもよい。この形態でも、水素の需要の変動が小さいときはバッファータンク13の緩衝機能によってその変動を吸収させ、水素の需要量の変動が大きくなったときは、貯蔵タンク15に過剰分の水素を圧縮貯蔵すること、又は、貯蔵タンク15から不足分の水素の供給を行うことにより、実施形態1及び2と同様の作用効果を得ることができる。
