AbstractNowadays, hydrogen has become not only an extremely important chemical product but also a promising clean energy carrier for replacing fossil fuels. Production of molecular H2 through electrochemical hydrogen evolution reactions is crucial for the development of clean-energy technologies. The development of economically viable and efficient H2 production/oxidation catalysts is a key step in the creation of H2-based renewable energy infrastructure. Intrinsic limitations of both natural enzymes and synthetic materials have led researchers to explore enzyme-induced catalysts to realize a high current density at a low overpotential. In recent times, highly active widespread numerous electrocatalysts, both homogeneous or heterogeneous (immobilized on the electrode), such as transition metal complexes, heteroatom- or metal-doped nanocarbons, metal-organic frameworks, and other metal derivatives (calix [4] resorcinols, pectates, etc.), which are, to one extent or another, structural or functional analogs of hydrogenases, have been extensively studied as alternatives for Pt-based catalysts, demonstrating prospects for the development of a “hydrogen economy”. This mini-review generalizes some achievements in the field of development of new electrocatalysts for H2 production/oxidation and their application for fuel cells, mainly focuses on the consideration of the catalytic activity of M[P2N2]22+ (M = Ni, Fe) complexes and other nickel structures which have been recently obtained.

The Capability Approach

This paper reflects on criticisms raised in the literature on the UN’s Sustainable Development Goals (SDGs). These have been criticized as creating a dichotomy between the environment and human beings that fails to address the multiple interconnections between the two. This paper focuses on SDG7—“affordable and clean energy”—and suggests that there is in fact a tripartite distinction between the environment, human beings and technology underlying the SDGs. This distinction, we argue, does not adequately represent the multiple interconnections among the various SDGs and hampers their implementation. We contend that the formulation of SDG7 produces a circular definition of sustainability, a difficulty that is currently resolved at the level of the targets and indicators in a way that regards energy technologies primarily as artifacts. By contrast, the literature on ethical aspects of energy systems largely agrees that energy is a paradigmatic example of a sociotechnical system. We contend that, by not considering this sociotechnical nature, the SDGs run the risk of implicitly defending a certain variant of technological optimism and determinism. We argue that this is disadvantageous to the environment, human well-being and technological development. In line with recent critical evaluations of the SDGs, we argue that these (and other) shortcomings can be addressed by better connecting the SDGs to human well-being. Building on recent literature that expands the scope of the Capability Approach as an alternative measure of well-being so as to include considerations of sustainability, we articulate a framework that allows us to elucidate this connection and thus to take advantage of synergies between human well-being and the environment. On the basis of the Capability Approach, we argue that equating sustainable energy with renewable energy—as is done in the transition from SDG7’s goal to its targets—is indefensible because, as part of the overarching energy systems, energy technologies cannot be classified as simply right or wrong. Rather, the indicators and targets within a framework focused on sustainability need to be (more) context sensitive, meaning that, among other things, they may vary by country and with the available technology.

Integrated photovoltaic-fuel cell (IPVFC) systems, amongst other integrated energy generation methodologies are renewable and clean energy technologies that have received diverse research and development attentions over the last few decades due to their potential applications in a hydrogen economy. This article systematically updates the state-of-the-art of IPVFC systems and provides critical insights into the research and development gaps needed to be filled/addressed to advance these systems towards full commercialisation. The design methodologies, renewable energy-based microgrid and off-grid applications, energy management strategies, optimisations and the prospects as self-sustaining power source were covered. IPVFC systems could play an important role in the upcoming hydrogen economy since they depend on solar hydrogen which has almost zero emissions during operation. Highlighted herein are the progresses as well as the technical challenges requiring research efforts to solve to realise numerous potential applications of IPVFC systems such as in unmanned aerial vehicles, hybrid electric vehicles, agricultural applications, telecommunications, desalination, synthesis of ammonia, boats, buildings, and distributed microgrid applications.

Global warming is increasing; therefore, Change is the law of nature. The changes like the environmental and climatic conditions, are one of the most complicated issues faced by the growing society. The survival of the fittest contributes to the idea of adaptation to the changes in society. Today’s business is all about being green, and companies use this as a key strategy to expand its market and impact society. Even the top companies like Amazon to apple are moving in a great way towards green. The economic development lies in the palms of the banks being the financial organizations.Green banking means a financial institution, typically public or quasi-public, that uses innovative financing techniques and market development tools in partnership with the private sector to accelerate deployment of clean energy technologies. Green banks use public funds to leverage private investment in clean energy technologies that, despite being commercially viable, have struggled to establish a widespread presence in consumer markets. Green banks seek to reduce energy costs for ratepayers, stimulate private sector investment and economic activity, and expedite the transition to a low-carbon economy. Adoption of green banking practices will not only be useful for the environment but also benefit in greater operational efficiencies, minimum errors and frauds, and cost reductions in banking activities. The present paper aims to highlightIndian initiatives and adoption by various banks towards green banking in India. Further, an attempt has been made to highlight the major benefits, confronting challenges of Green Banking.

Valley Of Death

This article seeks to describe the geography of clean tech investment which has emerged in recent years in the USA and the UK. An empirical approach was used, relying on close-dialogue interviews with senior investment managers in both markets. The article draws three conclusions. First, clean tech investment is often strongly influenced by physical geography, particularly in the area of renewable energy technologies. Second, regulatory settings play a strong role in the flow of investment. Third, capital flows unevenly between the different stages of technological maturity in clean energy products — a phenomenon which has been described as the ‘valley of death’ financing gap.
