“…This further begs the question: Are both hydrogen and batteries needed for the electrification of passenger vehicles and buses? Some scholars have explicitly considered this question [6] or tackled other examples of competing decarbonisation technologies such as nuclear verses renewables [101]. Yet, with most scholarship focused on single technologies or socio-technical systems, there is room for more consideration of competing decarbonisation technologies in the field of energy governance and sustainability transitions.…”

As policymakers and automotive stakeholders around the world seek to accelerate the electrification of road transport with hydrogen, this study focuses on the experiences of Germany, a world leader in fuel cell technology. Specifically, it identifies and compares the drivers and barriers influencing the production and market penetration of privately-owned fuel cell electric passenger vehicles (FCEVs) and fuel cell electric buses (FCEBs) in public transit fleets. Using original data collected via a survey and 17 interviews, we elicited the opinions of experts to examine opportunities and obstacles in Germany from four perspectives: (i) the supply of vehicles (ii) refuelling infrastructure, (iii) demand for vehicles, and (iv) cross-cutting institutional issues. Findings indicate that despite multiple drivers, there are significant challenges hampering the growth of the hydrogen mobility market. Several are more pronounced in the passenger FCEV market. These include the supply and cost of production, the lack of German automakers producing FCEVs, the profitability and availability of refuelling stations, and low demand for vehicles. In light of these findings, we extract implications for international policymakers and future studies. This study provides a timely update on efforts to spur the deployment of hydrogen mobility in Germany and addresses the underrepresentation of studies examining both buses and passenger vehicles in tandem.

“…Supply of energy produced from fossil fuels to fulfil continuously increasing global energy demand has recently surged and given rise to increased greenhouse gases resulting in global warming and associated detrimental effects on climate change [1–4] . The development of carbon‐neutral and carbon‐negative alternatives to fossil fuel is possibly the most researched area, and has been for several decades [5,6] . Owing to high energy density and carbon free combustion, hydrogen is considered as an ideal and sustainable energy carrier [7,8] .…”

Single‐Step and Sustainable Fabrication of Ni(OH)₂/Ni Foam Water Splitting Catalysts via Electric Field Assisted Pulsed Laser Ablation in Liquid

The prevailing barrier to produce hydrogen from water splitting is disappointingly sluggish kinetics. Furthermore, a lack of understanding of the key obstacle in the oxygen evolution reaction (OER), is an obstruction to the design of efficient water‐splitting electrocatalysts. Here, we present the single‐step and fast fabrication of ready‐made Ni(OH)2/nickel foam (NF) electrocatalysts for overall water splitting by using the environmentally friendly and sustainable approach of electric‐field‐assisted pulsed laser ablation in liquid for the generation of nanoparticles (NPs) and the simultaneous electrodeposition of the NPs on the NF substrate. The as‐fabricated electrocatalyst is found to be highly efficient and stable in alkaline medium for hydrogen evolution reaction (HER) and OER kinetics with remarkably low overpotentials of 187 mV (vs. RHE for HER) and 166 mV (vs. RHE for OER) to reach a current density of 20 mA cm−2, with HER and OER Tafel slopes of 82 and 69 mV dec−1, respectively. The two‐electrode electrochemical cell made of the bifunctional Ni(OH)2/NF electrocatalyst requires an overpotential as low as 168 mV to drive a 10 mA/cm2 current density over a long period. These results reveal the long‐term stability and activity of the Ni(OH)2)/NF electrocatalyst towards overall water (OW) splitting. The developed sustainable approach of electrocatalyst fabrication can be extended to a range of materials, beyond Ni(OH)2/NF, to boost a range of chemical reactions, beyond water splitting.

“…The COVID-19 has navigated the transitions of renewable and sustainable energy [ 95 ] and clean energy, including nuclear energy [ 96 ]. According to data from 123 countries over 25 years, Sovacool et al [ 97 ] found that, compared to renewables, nationwide nuclear attachments do not necessarily associate with lower carbon emissions significantly. More attention and personalised assessment, with a consideration of the environment in different countries, are urgently required to navigate the energy transitions under the COVID-19 pandemic.…”

The coronavirus disease 2019 (COVID-19) pandemic has magnified the insufficient readiness of humans in dealing with such an unexpected occurrence. During the pandemic, sustainable development goals have been hindered severely. Various observations and lessons have been highlighted to emphasise local impacts on a single region or single sector, whilst the holistic and coupling impacts are rarely investigated. This study overviews the structural changes and spatial heterogeneities of changes in healthcare, energy and environment, and offers perspectives for the in-depth understanding of the COVID-19 impacts on the three sectors, in particular the cross-sections of them. Practical observations are summarised through the broad overview. A novel concept of the healthcare–energy–environment nexus under climate change constraints is proposed and discussed, to illustrate the relationships amongst the three sectors and further analyse the dynamics of the attention to healthcare, energy and environment in view of decision-makers. The society is still on the way to understanding the impacts of the whole episode of COVID-19 on healthcare, energy, environment and beyond. The raised nexus thinking could contribute to understanding the complicated COVID-19 impacts and guiding sustainable future planning.
