Abstract:
... Small-scale liquefied natural gas (LNG) processes have gained considerable attention owing to the development of offshore natural gas (NG) reserves. Low energy efficiency and high process costs are the major challenges associated with small-scale LNG processes. In this study, to reduce energy consumption and improve process economics, a dual-phase expander-based process assisted by carbon dioxide ...

Abstract:
... The debate on firm’s investment decision under uncertainty is still unsettled. This study empirically examines the impact of firm-level political risk on contemporaneous capital and operating investment decisions. Using the text-based measure of firm-level political risk for US firms developed by Hassan et al. (2019), we show that when firms face higher political risk, they reduce the irreversible ...

Abstract:
... Decentralized water technologies such as rainwater harvesting (RWH) and greywater recycling (GWR) can supplement centralized urban water systems, helping reduce water withdrawal and improve water reliability. These benefits only emerge when decentralized water technologies are widely implemented. Several decision-supporting frameworks have been developed to identify suitable locations for deployin ...

Abstract:
... Compressed air energy storage has attracted worldwide attention owning to its low capital investment, scalability, eco-friendliness and long life. In this paper, a new combined thermal-compressed air energy storage with ejector-assisted superheated Kalina cycle is comprehensively investigated. Parametric assessment at the aspect of thermodynamic and economic performances is first conducted to inve ...

Abstract:
... Moving away from fossil fuels to cleaner energies is a big challenge in different industries due to its complexities and the huge capital investment needed. Manufacturers therefore need efficient energy transition planning to enhance their energy basket. In this regard, capacity expansion planning models can provide an appropriate context in which operations decisions can be integrated into energy ...

Abstract:
... Deeply understanding the driving effect of green finance on green development is of great significance to promote economic transformation and realize the long-term green development. This paper uses the entropy method and undesirable-SE-SBM model to measure provincial green finance and green development efficiency respectively from 2008 to 2018. And based on the above, the panel threshold model is ...

Abstract:
... There has been increasing attention in recent years on the use of photobioreactors for various biotechnological applications, especially for the cultivation of microalgae. Photobioreactors-based production of photosynthetic microorganisms furnish several advantages as minimising toxicity and providing improved conditions. However, the designing and scaling-up of photobioreactors (PBRs) remain a ch ...

Abstract:
... A techno-economic analysis was conducted to compare 3 different processes for biodiesel production: (i) the conventional base-catalysed process (NaOH) (ii) a reactive coupling process to form glycerol carbonate (GLC) as a co-product in situ (iii) a reactive coupling to form solketal as a co-product in situ. The processes were simulated at rapeseed oil feed of 100,000 t/y. The capital investment an ...

Abstract:
... Accelerating the promotion of high-quality development of tourism (HQDT) is of great significance to the sustainable development of tourism. This paper defined the concept of HQDT, and then built an evaluation system for HQDT measurement to analyze the spatio-temporal evolution characteristics of China’s HQDT based on provincial panel data from 2010 to 2019, using Geodetector to explore the simila ...

One cause of the high rate of COVID-19 cases in the USA is thought to be insufficient prior capital investment in national health programs to preemptively reduce the likelihood of an outbreak and in national capacity to reduce the severity of any outbreak that does occur. We analyze the choice of capital investments (e.g. testing capacity, stockpiles of PPE, and information sharing capacity) and f ...

Abstract:
... Forest harvesting machines have become technologically advanced, making them more productive but also more complex and expensive to purchase. Logging contractors have the challenge of deciding the right duration for operating their machines to optimize the high initial capital investment of purchasing new equipment. We evaluated the decline in ground-based mechanized logging equipment value in the ...

Abstract:
... The US Inflation Reduction Act of 2022 imposed a 1% excise tax on share repurchases. We can learn from corporate reaction to such a new policy in India. The Indian federal government recently levied a 20 percent tax, plus surcharge, on share repurchases. We show that companies did not slow down their share repurchase initiation. However, to offset the added taxes, they increased their capital inve ...

Abstract:
... While now appears appropriate to assert that digital finance can relieve firms’ financing constraints, the picture of whether it can improve enterprises’ green investment is much less clear. Using 2011–2019 data for Chinese listed heavily polluting (HP) enterprises, we examine the effects of digital finance on corporate green investment. Results show that digital finance impedes HP firms’ green in ...

Abstract:
... To reduce carbon emissions, the Chinese government is considering introducing a differentiated industrial carbon tax on enterprises outside the carbon trading market in the future. An efficient carbon tax must consider not only how carbon taxes impact the current economy but also how the size of the tax should be adjusted across time due to external changes. To calculate the optimal industrial car ...
