Energy Storage Performance and Investigation of Usage Potential a PV Combined-Alkaline Electrolysis Hydrogen Production System

Abstract

Hydrogen fuel has the potential to reduce CO2 emissions significantly. In this study, PV-alkaline electrolysis cell was combined and during day time it was harvested energy. Some of the deposited energy was used on-grid alkaline electrolysis cell and hydrogen was produced also was stored. In the electrolysis system, Ni-based coatings were operated on steel mesh with the help of the electrodeposition method. It was used re-cycled steel mesh substrates in order to decrease operational costs and also in order to encourage metal-cycling in our country. The relevancy of cathodes was investigated using bulk electrolysis. The characterization was achieved via scanning electron microscopy (SEM), energy dispersive X-ray analysis (EDX). Results define both effects of "lab-made cathodes performance comparison" and "the trend of PV panel under different climate and weather conditions". This system reflects the real-time measurements for Adana, Sarıcam region of Turkey.

Birleşik PV-alkali elektroliz hidrojen üretim sisteminin enerji depolama performansı ve kullanım potansiyelinin araştırılması

Öz

Hidrojen yakıtı, CO2 emisyonlarını önemli ölçüde azaltma potansiyeline sahiptir. Bu çalışmada PV-alkalin elektroliz hücresi birleştirilmiş ve gün boyunca enerji toplanmıştır. Depolanan enerjinin bir kısmı şebekede alkali elektroliz hücresinde kullanılmış ve hidrojen de depolanmıştır. Elektroliz sisteminde Ni esaslı kaplamalar, elektrodepozisyon yöntemi yardımıyla çelik hasır üzerinde çalıştırılmıştır. Ülkemizde işletme maliyetlerini düşürmek ve ayrıca metal çevrimini teşvik etmek amacıyla geri dönüşümlü çelik hasır substratları kullanılmıştır. Katotların uygunluğu, elektroliz yöntemi kullanılarak araştırıldı. Karakterizasyon, taramalı elektron mikroskobu (SEM), enerji dağılımlı X-ışını analizi (EDX) ile sağlandı. Sonuçlar, hem "laboratuvar yapımı katot performans karşılaştırmasının" etkilerini hem de "farklı iklim ve hava koşulları altında PV panelinin eğilimini" tanımlar. Bu sistem, Türkiye'nin Adana, Sarıçam bölgesi için gerçek zamanlı ölçümleri yansıtmaktadır.
