“…The existing literature on clean hydrogen is focused largely on production technology options, extended in some cases to consider storage and transport, with analyses of supply-side costs 10 . Discussion of demand is focused largely on the transportation sector in developed countries, on hydrogen fuel-cell vehicles in particular 11,12 .…”

Countries such as China are facing a bottleneck in paths to carbon neutrality: abating emissions in heavy industries and heavy-duty transport. There are few in-depth studies of the prospective role for clean (green/blue) hydrogen in these “hard-to-abate” (HTA) sectors. Are current mitigation technologies in HTA sectors effective? What are the roles for clean hydrogen towards carbon neutrality? We carry out an integrated modeling analysis to answer these questions. Results show that, first, clean hydrogen as both energy carrier and feedstock can significantly reduce heavy industry emissions. Second, clean hydrogen can fuel up to 50% of China’s heavy-duty truck and bus fleets by 2060 together with significant shares of shipping. As a side benefit, a realistic hydrogen scenario, reaching 65.7 Mt of production in 2060, could avoid $1.72 trillion new investment cost compared to a no-hydrogen scenario. This study provides strong evidence for countries facing challenges similar to China in addressing requirements to reduce emissions from their recalcitrant HTA sectors towards carbon neutrality.

“…Bu beklentilere ek olarak; sürdürülebilir, verimli, temiz, güvenilir ve kaliteli bir enerji kaynağı söz konusu olduğunda akla gelen en makul alternatif hidrojendir. Hidrojen üretimi ve saklanması konusundaki gelişmeler hirojenin yaygın kullanım ihtimalinin gerçek olmasını sağlayacaktır [6][7][8][9][10][11] Hidrojenin yaygın olarak kullanımını kısıtlayan temel sorunlardan biri depolama problemidir [12,13]. Hidrojenin saklanmasında ilk akla gelen teknik yüksek basınç kullanmak olsa da hidrojenin düşük moleküler kütlesinden dolayı enerji yoğunluğu kısıtlanmaktadır [14].…”

Yapılan çalışmada Al2O3 destek üzerinde ikili Co-Fe ve üçlü Co-Fe-Pt katalizörleri emdirme tekniği ile sentezlenmiştir. Üretilen katalizörler ile alkali ortamda NaBH4'ün tepkime vermesi sağlanmış ve hidrojen üretim hızı ve kinetik verileri derlenmiştir. Katalizörlerin morfolojik ve boyutsal özelliklerinin anlaşılması maksadı ile taramalı ve geçirimli electron mikroskop (SEM ve TEM) analizleri, hidrojen üretim kapasiteleri ve kinetik verilerin belirlenmesi için ise hidroliz testleri gerçekleştirilmiştir. İki ve üç bileşenli katalizörlerden Co0,95Fe0,05/Al2O3 ve Co0,85Fe0,08Pt0,07/Al2O3 kendi gruplarında en iyi performansı sergilemişlerdir. 40 mg Co0,85Fe0,08Pt0,07/Al2O3 katalizörü ile 20 ˚C sıcaklıkta, 12.750 mL H2/gkat.min hidrojen üretim hızına erişilmiştir. NaBH4 ve katalizör miktarlarını farklılaştırılması ile yapılan çalışmalarda hidrojen üretim hızının katalizör miktarı ile orantılı olduğu ve NaBH4 miktarının tepkime hızına etki mertebesinin 0,22 olduğu görülmüştür. Yüksek aktivite sergileyen Co0,85Fe0,08Pt0,07/Al2O3 katalizörünün aktivasyon enerjisi 26,17 kJ/mol olarak hesaplanmıştır. Bu katalizörün tekrar kullanımlarındaki dönüşüm değerleri aktivitesine oranla daha tatmin edici düzeydedir.

“…Electrolysis can be further divided into alkaline, solid oxide, PEM, AEM, acidic-alkaline amphoteric, microbial and photoelectrochemical, as depicted in Figure 1. At present, nonrenewable, fossil fuel-based processes, specifically, steam reforming of methane, coal gasification and other chemical processes, account for 96% of worldwide hydrogen generation, with electrolysis contributing just 4% [25][26][27][28]. Nonetheless, hydrogen originating from fossil fuels is low in purity and leads to the release of greenhouse gases including carbon monoxide, sulfur oxides, nitrogen oxides and carbon dioxide [19,29,30].…”

Membrane-Based Electrolysis for Hydrogen Production: A Review

et al. 2021

Hydrogen is a zero-carbon footprint energy source with high energy density that could be the basis of future energy systems. Membrane-based water electrolysis is one means by which to produce high-purity and sustainable hydrogen. It is important that the scientific community focus on developing electrolytic hydrogen systems which match available energy sources. In this review, various types of water splitting technologies, and membrane selection for electrolyzers, are discussed. We highlight the basic principles, recent studies, and achievements in membrane-based electrolysis for hydrogen production. Previously, the NafionTM membrane was the gold standard for PEM electrolyzers, but today, cheaper and more effective membranes are favored. In this paper, CuCl–HCl electrolysis and its operating parameters are summarized. Additionally, a summary is presented of hydrogen production by water splitting, including a discussion of the advantages, disadvantages, and efficiencies of the relevant technologies. Nonetheless, the development of cost-effective and efficient hydrogen production technologies requires a significant amount of study, especially in terms of optimizing the operation parameters affecting the hydrogen output. Therefore, herein we address the challenges, prospects, and future trends in this field of research, and make critical suggestions regarding the implementation of comprehensive membrane-based electrolytic systems.
