Super-Hydrophilic Leaflike Sn4P3 on the Porous Seamless Graphene-Carbon Nanotube Heterostructure as an Efficient Electrocatalyst for Solar-Driven Overall Water Splitting.

Water splitting using renewable energy resources is an economic and green approach that is immensely enviable for the production of high-purity hydrogen fuel to resolve the currently alarming energy and environmental crisis. One of the effective routes to produce green fuel with the help of an integrated solar system is to develop a cost-effective, robust, and bifunctional electrocatalyst by complete water splitting. Herein, we report a superhydrophilic layered leaflike Sn4P3 on a graphene-carbon nanotube matrix which shows outstanding electrochemical performance in terms of low overpotential (hydrogen evolution reaction (HER), 62 mV@10 mA/cm2, and oxygen evolution reaction (OER), 169 mV@20 mA/cm2). The outstanding stability of HER at least for 15 days at a high applied current density of 400 mA/cm2 with a minimum loss of potential (1%) in acid medium infers its potential compatibility toward the industrial sector. Theoretical calculations indicate that the decoration of Sn4P3 on carbon nanotubes modulates the electronic structure by creating a higher density of state near Fermi energy. The catalyst also reveals an admirable overall water splitting performance by generating a low cell voltage of 1.482 V@10 mA/cm2 with a stability of at least 65 h without obvious degradation of potential in 1 M KOH. It exhibited unassisted solar energy-driven water splitting when coupled with a silicon solar cell by extracting a high stable photocurrent density of 8.89 mA/cm2 at least for 90 h with 100% retention that demonstrates a high solar-to-hydrogen conversion efficiency of ∼10.82%. The catalyst unveils a footprint for pure renewable fuel production toward carbon-free future green energy innovation.

The impact of heterogeneous environmental regulations on the technology innovation of urban green energy: a study based on the panel threshold model

<abstract> <p>Since the Porter hypothesis was proposed, environmental regulation has been recognized as a critical factor influencing technology innovation. However, there is no unified conclusion on whether the relationship between the two is linear or non-linear, and environmental regulation is always examined from single angles. Therefore, according to the difference of environmental regulation implementation subjects, this paper divides environmental regulation into formal regulation and informal regulation. Utilizing the panel data of 281 prefecture-level and above cities in China from 2011-2019, the non-linear effects of heterogeneous environmental regulations on green energy technology innovation are analyzed based on the panel threshold model, and the non-linear relationship between the two under the difference in urban economic development level is further considered. The results indicate that: (1) The threshold effect of the environmental regulations on China's green energy technology innovation is significant, and there is heterogeneity in the effects of different environmental regulations. (2) At present, positive relationship are observed between the informal environmental regulation and green energy technology innovation in China, while the formal environmental regulation exerts a significant inhibitory effect on green energy technology innovation. (3) The level of regional economic development plays a significantly positive role in moderating the relationship between environmental regulation and green energy innovation. However, there exists a certain heterogeneity in the moderating role between the formal regulation-innovation link and informal regulation-innovation relationship. This study provides a reference for further clarifying the relationship between heterogeneous environmental regulations and green energy technology innovation.</p> </abstract>

Escalation effect of fossil-based CO2 emissions improves green energy innovation

The 21st-century development pathway is facing a challenge between climate change mitigation, sustained economic prosperity, and energy security. While extant literature focuses on drivers of anthropogenic emissions, the role of policy measures including green energy innovation, and energy research and development are limited in scope. Here we develop conceptual tools across IEA member countries with four decades of data that demonstrate the role of green energy innovation, and research and development in reducing emissions. Our assessment reveals that sectoral fossil-based CO2 contributes directly to GHG emissions by 29.7–40.6% from transport, 24.6–32% from industry, 18.6–19.5% from buildings, 15–18.4% from other sectors, and 0.5–1.1% from power. We highlight that industrialized high-income countries converge on green energy innovation but diverge on emissions. The empirical evidence shows that achieving green growth is possible through green energy innovation amidst climate change and its impact.

Environmental Policy Integration in the Energy Sector of China: The Roles of the Institutional Context.

The rapid growth of China’s renewable energy market and production capacity has attracted worldwide attention. Environmental policy integration in the energy sector and the institutional background behind this growth have seen little examination. In this paper, we present an assessment of environmental policy integration (EPI), attempting to reveal how the institutional factors facilitate EPI in the energy sector of China. A qualitative analytical framework involving normative, organizational, and procedural dimensions, incorporating multiple pieces of quantitative evidence, was applied. The results show that an ambitious and long-term normative vision covering political will, social backing, and cultural foundation in China is indispensable to the EPI process in the energy sector. The energy agency’s trans-sector cooperation in policy-making has been established to overcome the sectoral compartmentalization. China’s EPI in energy has a relatively complete and stable regulating system but, at the same time, it is expected to obtain more benefits from market cultivation and public participation. In this process, advantages such as the co-evolution of the green energy innovation, market, and society do exist; however, this market-oriented approach may bring the risk of economic and societal disturbances when interest-driven production capacity growth far surpasses market and societal requirements. This potential risk needs to be handled and prevented by strong governmental guidance and support. The continuous ambitious and long-term visioning of EPI, sufficient governmental funds, and a proactive industrial plan for renewable energy, are suggested.

Does Energy Price Induce China’s Green Energy Innovation?

This paper aims to comprehensively analyze the relationship between energy price and green energy innovation in China, and first studies the impact of energy price on China’s green energy innovation, then further investigates the moderating role of energy price distortion in the price–innovation relationship, especially in the context of lagging energy marketization level in the process of China’s transition from planned economy to the market economy. Based on the data of 30 provinces in China from 2003 to 2017, this paper provides a measurement of green energy innovation capacity through the number of “alternative energy production” and “energy conservation” patents. Our results show that energy price has a significantly positive impact on China’s green energy innovation, no matter the number of green energy patent applications or the number of green energy patent grants is used as the proxy of green energy innovation capacity. However, there exists heterogeneity related to the influence of energy price on green energy innovation. Specifically, energy price has a noticeable role in promoting green energy innovation in central and western China, but not in eastern China. Further research results show that energy price distortion significantly reduces the inducing effect of energy price on green energy innovation. Meanwhile, the distortion degrees of energy price in the central and western regions of China are significantly lower than that in the eastern region, which explains to a large extent why the inducing effect of energy price on innovation is more prominent in the central and western regions.

The Moderating Role of Green Energy and Energy-Innovation in Environmental Kuznets: Insights from Quantile-Quantile Analysis

Background. The recent environmental challenges in Africa emanated from global warming, human activity, limited access to electricity, and over-exploitation of natural resources, have contributed to the growth of carbon dioxide (CO2) emissions in the region. Objective. This paper empirically investigates the moderating role of green energy consumption and energy innovation in the environmental Kuznets’ curve for the Sub-Saharan African (SSA) region using data spanning from 1980 to 2018. Methods. A sample of 45 SSA countries for the period between 1980-2018 was studied. To solve for potential heteroscedasticity and endogeneity issues, we performed 2sls and panel quantile regression to give inference at various quantiles. Discussion. Empirical results confirm that green energy, energy innovation and natural resource abundance mitigate pollution in the SSA region. Besides, a threshold effect of energy innovation is estimated, which indicates the amount of energy innovation that SSA would require to reduce environment degradation. Our threshold model found that atleast 54 per cent of population need access to energy innovation before the region could be safe from environmental degradation. Conclusions. We conclude that investment in green energy, energy innovation, and conservation of natural resources will help to mitigate environmental degradation in SSA in the long run. Policies should be targeted towards encouraging the consumption of green energy, and more investment in energy innovation beyond the estimated threshold will save the region from pollution and its implications. Contribution: This study has contributed to the existing studies in different ways. This is the first study to explore the impact of green energy and energy innovation in SSA. We contribute to this line of research by implementing quantile techniques to examine the role of green energy and energy innovation in the environmental Kuznets’ hypothesis. In addition, our threshold estimation provides practical implications for policy applications.

Finally, we find that these newly identified shocks have distinct consequences for the U.S. economy: precautionary demand shocks reduce real GDP, while speculative demand shocks cause inflation.

Energy intensity and green energy innovation: Checking heterogeneous country effects in the OECD

Over the recent years, there has been evidence of a decline in energy intensity worldwide. Most of this decline was industry or sector specific. The main aim of the quantitative analysis is to enhance the understanding of how green energy innovative activities are entangled with energy intensity in the OECD through models that take into account heterogeneity and serial correlation. The existing literature does not fully address this country related heterogeneity in either the short- or long-run scales. We use some specific estimators that address those key econometric issues. The analysis specifically focuses on the dynamics of green energy innovation and finds the existence of both short-term and long-term relationships between energy intensity and green energy innovative activities, though this relationship loses its significance over time.

These demonstrate the potential for nature derived materials in green energy innovation.

Energy Prices, Technological Knowledge, and Innovation in Green Energy Technologies: a Dynamic Panel Analysis of European Patent Data

We examine the effect of energy prices and technological knowledge on innovation in green energy technologies. In doing so, we consider both demand-pull effects, which induce innovative activity by increasing the expected value of innovations, and technology-push effects, which drive innovative activity by extending the technological capability of an economy. Our analysis is conducted using patent data from the European Patent Office on a panel of 26 Organization for Economic Co-operation and Development countries over the period 1978–2009. Utilizing a dynamic count data model for panel data, we analyze 11 distinct green energy technologies. Our results indicate that the existing knowledge stock is a significant driver of green energy innovation for all technologies. Furthermore, the results suggest that energy prices have a positive impact on innovation for some but not all technologies, and that the effect of energy prices and technological knowledge on green energy innovation becomes more pronounced after the Kyoto protocol agreement in 1997 (JEL codes: C33, O31, Q40, Q42, Q55).
