“…Delivery systems are through three main methods: gaseous pipelines; pressurized tube trailers; cryogenic liquid tankers [8]. Hydrogen energy can be used through two key pathways: fuel cells and combustion [9]. Fuel cells produce electricity, while combustion is used in boilers and engines [10].…”

Adoption of hydrogen energy as an alternative to fossil fuels could be a major step towards decarbonising and fulfilling the needs of the energy sector. Hydrogen can be an ideal alternative for many fields compared with other alternatives. However, there are many potential environmental challenges that are not limited to production and distribution systems, but they also focus on how hydrogen is used through fuel cells and combustion pathways. The use of hydrogen has received little attention in research and policy, which may explain the widely claimed belief that nothing but water is released as a by-product when hydrogen energy is used. We adopt systems thinking and system dynamics approaches to construct a conceptual model for hydrogen energy, with a special focus on the pathways of hydrogen use, to assess the potential unintended consequences, and possible interventions; to highlight the possible growth of hydrogen energy by 2050. The results indicate that the combustion pathway may increase the risk of the adoption of hydrogen as a combustion fuel, as it produces NOx, which is a key air pollutant that causes environmental deterioration, which may limit the application of a combustion pathway if no intervention is made. The results indicate that the potential range of global hydrogen demand is rising, ranging from 73 to 158 Mt in 2030, 73 to 300 Mt in 2040, and 73 to 568 Mt in 2050, depending on the scenario presented.

“…However, it is observed that in past, CO 2 reduction in industries was not considered to be taken into consideration to mitigate its emissions. More recently, it is expected that the CO 2 must be mitigated by introducing the hybrid system of energy just like hybrid fuel powered cars that will play a significant role in reducing carbon emission worldwide [19,20,22,23]. Moreover, it is believed that hydrogen fuel could be used as a clean fuel that after burning it produces water, which results in less CO 2 emissions.…”

“…According to recent assessments, the tight gas potential of Pakistan is believed to be in the range of 24 TCF to 40 TCF in different basins of the country [9,12]. The tight gas potential is also found in the prevailing (D&P) Development and Production Leases of the country [22][23][24]. The Goru formation along with some limestone and Siltstones in the sedimentary basin of Pakistan also possesses tight gas potential in large quantity [37].…”

Climate change is one of the most challenging issues in Pakistan and has affected humans in every sphere of life. Pakistan is ranked on 8th in the world among the countries emitting Greenhouse gases (GHG). Such an extensive emission of GHG is due to the growing number of industrial units and urban centres consuming fossil fuels that emit GHG at a large scale. Mitigating the GHG emission indeed is a challenge for Pakistan. This manuscript highlights the GHG emission status and provides recommendations with suitable alternatives to mitigate the emission. Simultaneously, the study explores the impact of switching over the fuels from conventional fossil fuels to unconventional natural gas as a source of energy for domestic use, transportations and industrial sectors to mitigate the GHG emission. Natural gas is considered as green fuel due to the low carbon emission ratio as other fuels e.g. coal and oil. If Pakistan becomes successful in exploring and exploiting the indigenous untapped natural gas resources, that will eventually support in reducing the GHG emissions. This is only possible by making new natural gas reservoir discoveries. Discovering new gas reservoirs from unconventional resources is also very challenging and requires investment and modification in existing energy policies. In addition, the government should encourage the Exploration Production (EP) companies to exploit the hidden natural gas potential that will assist in both alleviating the energy deficit and reducing the GHG emission. The findings of the present study analysis have substantial implications regarding GHG mitigation, energy transition, and economic development.

“…Molecular hydrogen (H 2 ) is an energy carrier with high combustion yields [1]. Biologically produced H 2 , referred to as biohydrogen production (BHP), is considered an environmentally friendly clean alternative with near zero carbon emission and has potential to replace fossil fuels as energy carriers [2]. Comparing different BHP systems, two main parameters must be considered.…”

As a renewable energy carrier, dark fermentative biohydrogen (H2) represents a promising future alternative to fossil fuels. Recently, the limited H2 yield of 4 moles of H2 per mole glucose, the so-called “Thauer limit”, was surpassed by a defined artificial consortium. In this article, we demonstrate the upscaling of this drawing board design, from serum bottles to laboratory scale bioreactors. Our results illustrate that this designed microbial co-culture can be successfully implemented in batch mode, with maximum H2 yields of 6.18 and 4.45 mol mol−1 substrate. Furthermore, we report volumetric H2 productivities of 105.6 and 80.8 mmol H2 L−1 h−1. These rates are higher than for any other dark fermentative H2 production system using a synthetic microbial co-culture applied in batch mode on a defined medium. Our study is an important step forward for the application of artificial microbial consortia in future biotechnology and energy production systems.
