“…In the present time, electricity generation is mostly focused on hydrocarbon‐based fuels (coal, oil, etc.) due to their predictable nature and technical ability to generate at stable voltage; even being a major source of air pollution and conspicuous contributor toward global warming 1,2 . Whereas from environmental aspect, supremacy of renewable energy (RE) is an established fact.…”

Summary A novel dual mode wind turbine driven hybrid energy storage scheme with electromagnet based mode changing operation is proposed in this article. The hybrid storage system includes a pump storage hydroelectric system (PSH) and a vanadium redox flow battery. The proposed system provides uninterrupted energy at stable voltage to consumers in an isolated microgrid. The system is capable in handling different effects of wind speed‐related uncertainties at the load end, up to a certain limit. Advantages of the system lie in its reliability, operation simplicity, robustness, and energy output at stable voltage irrespective of normal wind speed variation. The proposed system also provides an idea of efficient usage of renewable energy. This article documents the proposed system structure, operation strategy, mathematical modeling, and simulation result using real wind speed data. The proposed system is found to be viable, upon simulation with a variable loading pattern.

Objective: The electricity-to-hydrogen technology can convert surplus renewable energy electric energy into chemical energy. Hydrogen plays an important role in transportation, power generation, and other fields. Therefore, developing electrochemical (P2X) technology for renewable energy consumption effectively solves renewable energy curtailment. Methods: The four aspects of market scale, technical route, energy conversion efficiency, and demonstration project progress are reviewed, and the energy efficiency of the four electrochemical technologies is compared, Power consumption, marginal electricity price, equivalent output, and market share five major technical and economic indicators. To analyze the strengths, weaknesses, opportunities, and threats of P2X in China, a literature review survey was conducted, relying on recent two-decade publications from four main publishers: Scopus, Springer, Wiley, and Taylor and Francis. Keywords were selected from the first-hand references based on their impact on P2X or related topics listed in the literature databases. The keywords as Power to X, Power to chemicals, PtX, and P2X were chosen according to their actual involvement or keen interest in P2X projects. Results: The research results based on the low-temperature electrolysis technology route show that the comprehensive energy efficiency of the electricity-to-methane and electricity-to-gasoline technologies is higher (50%); the electricity-to-gasoline technology is the most economical (marginal electricity price is 0.37 yuan/kWh), but the synthesis process requires carbon monoxide and carbon emissions, And the technical risk is high; the promotion of electricity to ammonia will have the greatest impact on the market (17.18%). Reducing coal consumption by about 22.85 million tons and the environmental protection significance of electricity-to-ammonia conversion (reducing carbon emissions by about 39.1 million tons) are two important directions for future electrochemical technology. Conclusion: Facing the development of P2X technology in the future, the plan and economics of the high-temperature electrical and chemical technology route based on high-temperature solid oxides were preliminary discussed and prospected.

“…Heavy-polluting enterprises are clearly the industrial carbon producers for they consume high-carbon energy, such as coal and petroleum, and are yet to innovate their technologies toward large-scale energy conservation. Some recent studies on heavy industrial enterprises have focused on exposing energy consumption and carbon dioxide emissions by Chinese firms, such as in the steel industry [42], the nonferrous metals industry [43], or the coal chemical industry [44], etc. Enterprises that take actions deemed as bad for the environment and the indigenous communities, however, can also take the guise of environmentally conscious companies or have associations with an international body.…”

Toward a new paradigm of environmentally friendly cultural values

Climate change gives rise to a growing threat of extinction to humankind, yet the current approach and solutions appear insufficient in addressing it effectively. This paper presents a critical review of the climate crisis and current approaches, highlighting how misguided would it be to exclude enterprises—the primary drivers of the climate problems—from top-down policy-making. In assessing the different core cultural values of environment-damaging and environment-protecting enterprises, the authors suggest embracing a new paradigm of environmentally-friendly cultural values. The new paradigm, which calls for a process of identifying, transforming, and synthesizing a set of core cultural values, serves as the cornerstone of the whole system and aims to shift the core cultural value from “exploitation” to “construction.” As environmentally-friendly cultural values can shape human progress away from capitalism/monetarism and toward environmentalism, it could be added to Harrison and Huntington’s (2001) list of human cultures as the 11th value. The paradigm comprises two mutually interacting attributes: (i) money cannot trade for environmental deficits, and (ii) environmental embellishment value needs to become a new “measure of profit,” priced at least on par with monetary value. The insights carry serious implications for policy-makers in engaging enterprises in the fight for a more habitable and sustainable planet.
