“…Using surplus electricity from fluctuating renewable energy sources to generate hydrogen via water electrolysis combined with hydrogen storage could play a key role in the transition toward a carbon neutral energy system. [ 1–4 ] Currently two electrolysis technologies, capable of directly utilizing electricity for water splitting, are available on a large scale commercial level: alkaline water electrolysis and proton exchange membrane water electrolysis (PEMWE). [ 5 ] PEMWE has a higher tolerance to differential pressures and current fluctuations as well as system shutdowns and cold‐starts.…”

High investment costs and a dependence on noble metal catalysts currently obstruct the large‐scale implementation of proton exchange membrane water electrolyzers (PEMWEs) for converting fluctuating green electricity into chemical energy via water splitting. In this context, this work presents a high‐performing and stable non‐noble metal catalyst for the hydrogen evolution reaction (HER), consisting of [Mo3S13]2− clusters supported on nitrogen doped carbon nanotubes (NCNTs). Strikingly, a significant electrochemically induced activation of the Mo3S13‐NCNT catalyst at high current densities is observed in full cell configuration, enabling a remarkable current density of 4 A cm−2 at a cell voltage of 2.36 V. To the authors’ knowledge, this is the highest reported value to date for a PEMWE full cell using a non‐noble metal HER catalyst. Furthermore, only a minor degradation of 83 µV h−1 is observed during a stability test of 100 h constant current at 1 A cm−2, with a nearly unchanged polarization behavior after the current hold. Catalyst stability and activity are additionally analyzed via online dissolution measurements. X‐ray photoelectron spectroscopy examination of the catalyst before and after electrochemical application reveals a correlation between the electrochemical activation occurring via electrodissolution with changes in the molecular structure of the Mo3S13‐NCNT catalyst.

“…However, this strategy has again raised an important question regarding cost-effectiveness, due to the inefficient process of conversion of biomass and the low energy efficiency [ 6 ]. To replace the direct conversion of lignocellulosic biomass to low-value fuel for the generation of heat and electricity, conversion to high-added value-quality bio-products and energy carriers has been proposed [ 7 ], aimed at the establishment of a bio-refinery concept. To achieve this, it is very important to make use of all the major components of lignocellulosic biomass, namely cellulose, hemicellulose, and lignin.…”

BackgroundThe aim of this work was to establish a process for the heterotrophic growth of green microalgae using forest biomass hydrolysates. To provide a carbon source for the growth of the green microalgae, two forest biomasses (Norway spruce and silver birch) were pretreated with a hybrid organosolv-steam explosion method, resulting in inhibitor-free pretreated solids with a high cellulose content of 77.9% w/w (birch) and 72% w/w (spruce). Pretreated solids were hydrolyzed using commercial cellulolytic enzymes to produce hydrolysate for the culture of algae.ResultsThe heterotrophic growth of A. protothecoides was assessed using synthetic medium with glucose as carbon source, where the effect of sugar concentration and the carbon-to-nitrogen ratio were optimized, resulting in accumulation of lipids at 5.42 ± 0.32 g/L (64.52 ± 0.53% lipid content) after 5 days of culture on glucose at 20 g/L. The use of birch and spruce hydrolysates was favorable for the growth and lipid accumulation of the algae, resulting in lipid production of 5.65 ± 0.21 g/L (66 ± 0.33% lipid content) and 5.28 ± 0.17 g/L (63.08 ± 0.71% lipid content) when grown on birch and spruce, respectively, after only 120 h of cultivation.ConclusionsTo the best of our knowledge, this is the first report of using organosolv pretreated wood biomass hydrolysates for the growth and lipid production of microalgae in the literature. The pretreatment process used in this study provided high saccharification of biomass without the presence of inhibitors. Moreover, the lipid profile of this microalga showed similar contents to vegetable oils which improve the biodiesel properties.

ÖZET Son yıllarda, tüm dünyada artan enerji ihtiyacının karşılanması ve çevresel sorunların çözümü için yenilenebilir kaynakların kullanımı giderek artmaktadır. Türkiye'de yenilenebilir enerji kaynaklarının kullanımını arttırmak ve enerji bağımlılığını azaltmak için çeşitli çalışmalar yapılmaktadır. Bu sebeple, Türkiye'deki alternatif enerji kaynağı arayışı biyogaz enerjisi üretiminin de yaygınlaşmasına sebep olmuştur. Özellikle tarım ve hayvancılığa uygun olan alanlarda oluşan organik atıklardan biyogaz enerji üretimini arttırmak için çalışmalar yapılmaktadır. Bu bölgelerde bitkisel ve hayvansal atıkların biyogaz enerji üretiminde kullanılması toplam enerji tüketiminin azaltılmasına ve atık yönetimine katkı sağlamaktadır. Bu çalışmada, Türkiye'nin İç Anadolu Bölgesi'nde yer alan Çankırı İl'inin biyogaz enerji potansiyeli ve kullanılabilirliği araştırılmıştır. Genellikle tarım ve hayvancılık sektörünün geliştiği, sanayileşme oranının düşük olduğu Çankırı İl'inde hayvansal atıklardan elde edilebilir biyogaz enerji potansiyeli belirlenmiştir. Biyokimyasal metan üretim potansiyeli (BMP) ve elektrik üretimine katkısı hesaplanarak her bir ilçe için ayrı ayrı bölgesel harita ve grafikleri oluşturularak biyogaz enerji potansiyeli analizi yapılmıştır. Ayrıca, biyogaz üretiminden elde edilecek elektrik geliri ve CO2 emisyon değerleri de hesaplanmıştır.
