２０２３年８月３０日 アフリカの水力開発は今後どうなるか，大規模な机上調査で示唆
世界の水力開発の焦点は，ヒマラヤ周りとアフリカに移ってきている，ヒマラヤ周りは，おそらくインドと中国などアジア周辺の国々の経済発展を支える方向だが，アフリカの水力は，アフリカに期待される経済発展もさることながら温暖化対策を進める欧州諸国の期待を担っている側面も考えられる
今日発表されたアイリッシュ紙（Irish Tech News）は，学者グループが，アフリカの水力開発について大規模な調査を実施したことを示唆し，その将来について，太陽光との比較の上で，必ずしも見通しは明るくない，との見解を示した，１９７０年の吉本等は，アフリカの水力包蔵は１１億ＫＷと
今回の報告はアフリカの水力の将来に悲観的な見方を示した，としているが，実際には短期的に水力開発が進むことも示唆している，特にミラノの学者の意見として，コンゴ，ニジェール，ナイルなど河川の流域では開発が有望としている，この報道に出ている集中的な調査の結果を見てみたいと思う

これは水力発電にとって「ゲームオーバー」を意味するのでしょうか？研究が説明するように、完全ではない。短期的には、いくつかの新しい水力発電所は、依然として必要な国に安価な電力を供給できる可能性があり、また、出力が常に変動する太陽光と風力の統合を支援するために柔軟に使用できる可能性がある。
「私たちのモデルは、どの特定の水力発電所が短期的にも依然として費用対効果が高いかを示しています」とミラノ工科大学天然資源管理教授であり、この研究の主著者であるアンドレア・カステレッティ教授はコメントする。「特にコンゴ、ニジェール、ナイル川流域では、綿密に計画され、環境への有害な影響が最小限に抑えられる限り、努力する価値のある特定のプロジェクトがあります。」
しかし、長期的には、太陽光発電はほとんどのアフリカ諸国で支持される明確な技術として浮上し、太陽光発電が間もなく世界中の電力市場の新たな「王」になるだろうという国際エネルギー機関の2020年の主張を反映している。
「アフリカの水力発電が実現可能な投資となる可能性は非常に急速に閉ざされつつある」と、ベルギーのブリュッセル自由大学（VUB）のエネルギー気象学の教授であり、世界資源研究所（WRI）の上級研究員でもあるセバスチャン・スタール教授は付け加えた。アディスアベバ、エチオピア。この研究は、2030 年を超えても、アフリカ全土で魅力的な投資対象となる水力発電所は非常に限られた数だけになるであろうことを示唆しています。「費用対効果は別として、これは環境にとっては一般的に良いニュースです。これは、多くの川がせき止められる必要がなく、自然の流れを維持できることを意味します」とスタール氏は結論づけています。
Abundant rainfall, massive gorges, enormous waterfalls: the geography of Africa has all the elements for producing electricity from river flow. For decades, many African countries have relied on hydropower for electricity generation, including projects that inspire as much awe as controversy. One only needs to think of Ghana’s Lake Volta, the largest artificial lake in the world; the Grand Ethiopian Renaissance Dam, Ethiopia’s flagship project to provide millions of its citizens with electricity access; or DR Congo’s dream of building the Grand Inga plant, which some claim could “light up all of Africa”. And the voices that advocate for more of the same are strong: it is estimated that Africa has barely exploited 10% of its hydropower potential.
“Our model shows which specific hydropower plants would still be cost-effective in the short-term,” comments Professor Andrea Castelletti, professor in Natural Resources Management at Politecnico di Milano and senior author of the study. “Especially in the Congo, Niger, and Nile basins, there are certain projects that would be worth the effort, as long as they are well-planned and harmful environmental effects are kept to a minimum.”
