“…For example, a system composed of [FeFe] hydrogenase embedded in a modified hydrogel has been used to achieve reversible hydrogen conversion, with a voltage of 1.16 V near the thermodynamic limit [ 167 ]. There is ongoing research into the commercial exploitation of these approaches in a variety of bio-enhanced systems, such as fuel cells, hydrogen production devices, and electrocatalysis [ 153 , 168 , 169 ]. Another hydrogenase of biotechnological interest is the ‘hydrogen-dependent CO 2 reductase’ (HDCR), which catalyzes the oxidation of hydrogen coupled to the reduction of CO 2 to form formate (see Section 2.1.2 ).…”

Biotechnology has a high potential to substantially contribute to a low-carbon society. Several green processes are already well established, utilizing the unique capacity of living cells or their instruments. Beyond that, the authors believe that there are new biotechnological procedures in the pipeline which have the momentum to add to this ongoing change in our economy. Eight promising biotechnology tools were selected by the authors as potentially impactful game changers: (i) the Wood–Ljungdahl pathway, (ii) carbonic anhydrase, (iii) cutinase, (iv) methanogens, (v) electro-microbiology, (vi) hydrogenase, (vii) cellulosome and, (viii) nitrogenase. Some of them are fairly new and are explored predominantly in science labs. Others have been around for decades, however, with new scientific groundwork that may rigorously expand their roles. In the current paper, the authors summarize the latest state of research on these eight selected tools and the status of their practical implementation. We bring forward our arguments on why we consider these processes real game changers.

“…All these NPs enhance biohydrogen production due to an increase in surface area and impact of the quantum measure [39,40]. The enzyme hydro-genase acts as a catalyst for the transformation of H 2 to protons, thereby diminishing the control from oxidation of hydrogen [41]. The production of H 2 using various NPs and their positive upshots are discussed in the following sections.…”

Application of Nanotechnology in the Production of Biohydrogen: A Review

Hydrogen is an outstanding source of energy that does not create any hostile carbon footprint as it produces only water during combustion. The application of nanotechnology is one of the recent advanced technologies used to enhance the rate of hydrogen production from biomass. The use of nanoparticles (NPs) in the conversion process enhances this rate. Biological methods such as dark fermentation and photobiological route of conversion of biomass to hydrogen are the most suitable and cost‐effective paths. Hydrogen production with nanotechnology in dark fermentation utilizes organic or inorganic NPs in the bioreactor membrane. The efficiency of biohydrogen production depends on the concentration and nature of the NPs used, and the kind of biowastes or biomass feed. The effectiveness of both processes is discussed.

“…Hydrogen metabolism is one of the most ancient processes of life, and today it is at the center of growing attention in the field of bioenergy (or bio-inspired) production technologies [ 1 , 2 , 3 , 4 , 5 ]. Hydrogenases are the enzymes responsible for the biological production or consumption of hydrogen in all domains, Archaea, Bacteria, and Eukarya [ 6 , 7 ].…”

Hydrogen production in nature is performed by hydrogenases. Among them, [FeFe]-hydrogenases have a peculiar active site, named H-cluster, that is made of two parts, synthesized in different pathways. The cubane sub-cluster requires the normal iron-sulfur cluster maturation machinery. The [2Fe] sub-cluster instead requires a dedicated set of maturase proteins, HydE, HydF, and HydG that work to assemble the cluster and deliver it to the apo-hydrogenase. In particular, the delivery is performed by HydF. In this review, we will perform an overview of the latest knowledge on the maturation machinery of the H-cluster, focusing in particular on HydF.
