📝 gxceed 編集解説 — Why this matters

日本のGX文脈において

小規模な水・エネルギー技術の効率改善事例として、日本の分散型再生可能エネルギーや地域の脱炭素技術導入の参考になり得るが、SSBJや開示制度との直接の接続は薄い。

In the global GX context

Adds a niche empirical data point on low-cost solar desalination efficiency and carbon-credit accounting, relevant to distributed renewable and water-energy nexus discussions but peripheral to mainstream TCFD/ISSB disclosure frameworks.

📄 Abstract（原文）

ABSTRACT This study investigates the thermodynamic and water‐production performance of a conventional tubular solar still (CTSS) compared with a tubular solar still (TSS) utilizing custard apple seeds (TSS–CAS). The cumulative distillate yield of the TSS–CAS reached 3.60 kg/day, significantly surpassing the 2.76 kg/day obtained by the CTSS, an increase of 30.43%. The TSS–CAS energy and exergy efficiencies were 39.78% and 3.12%, respectively, compared with 26.56% and 1.45% for the CTSS, indicating improved efficiency in both metrics. From an exergy perspective, destruction within the evaporation basin peaked at 1:00 PM, reaching 586.11 W/m 2 for the CTSS and 527.20 W/m 2 for the TSS–CAS; exergy destruction within the glass cover reached its maximum values of 39.23 and 51.20 W/m 2 , respectively. The study revealed that exergy destruction in the saline water was lower in the TSS–CAS, peaking at 138.13 W/m 2 , compared with the CTSS, which peaked at 157.63 W/m 2 , thereby demonstrating improved thermodynamic efficiency. The integration of bio‐seeds into TSS enhances heat retention and minimizes exergy losses in the saline water. The economic, environmental, and enviro‐economic evaluations corroborated the TSS–CAS's increased yield and efficiency. The relative improvement in total carbon credit earned and total carbon emission mitigation for the TSS–CAS was 30.91% and 30.92%, respectively.
