“…Coal‐fired power plants are major stationary sources of CO 2 and although CCS is the most mature route, it poses severe economic penalties to power generation 77 . A 500‐MW coal power plant releases 11 400 metric ton (MT) CO 2 day –1 78 .…”

“…proposed a route consisting of CO 2 biocapture by C. pyrenoidosa and use of the resulting biomass as feedstock to a microalgae‐based biorefinery. The integrated arrangement comprises: (i) CO 2 biocapture in a photobioreactor, (ii) oil extraction from part of the produced biomass and gasification of the remaining biomass to obtain biosyngas, and (iii) conversion of biosyngas to methanol 77 . The results showed CO 2 capture by microalgae to be a promising technology for mitigating CO 2 emissions, although technical drawbacks must be overcome.…”

Global warming caused by carbon dioxide (CO2) emissions is one of the most important topics of concern in the fields of science, environment and global economy. Carbon dioxide emissions have increased dramatically in recent years, and this trend is likely to continue with a projected increase of both global energy consumption and CO2 emissions by 51% in 2050 compared with 2005. To mitigate the negative impacts arising, a potential strategy to convert CO2 into renewable fuels or valuable chemicals can be applied. Bio‐CO2 emission reduction is receiving more and more attention as an environmentally friendly method. Microalgae are attracting worldwide attention in this regard owing to their exceptional speed of growth, resistance to harsh environments and low production costs. In this review, the biochemical principles of microalgae‐CO2 fixation and the research progress of microalgae strains used for CO2 fixation are reviewed and discussed. The latest progress in the co‐development of a microalgae carbon sequestration industry and other industries are provided, along with a survey of the progress in methods to improve microalgae‐CO2 fixation. Finally, the problems to be solved in the industry and its future directions of development are clarified. © 2021 Society of Chemical Industry (SCI).

“…Yet the NPV still has benefits and the global warming potential could be pronouncedly reduced. Wiesberg et al [49] also mentioned that carbon capture and storage pose a great economic penalty to power generation. It was suggested that authorities should support the shared investments of CO 2 capture installations.…”

The global COVID-19 pandemic has had strong impacts on national and international freight, construction and tourism industry, supply chains, and has resulted in a rapid decline in the demand for traditional energy sources. In fact, research has outlined that urban areas depend on global supply chains for their day-to-day basic functions, including energy supplies, food and safe access to potable water. The disruption of global supply chains can leave many urban areas in a very vulnerable position, in which their citizens may struggle to obtain their basic supplies, as the COVID-19 crisis has recently shown. Therefore, solutions aiming to enhance local food, water and energy production systems, even in urban environments, have to be pursued. The COVID-19 crisis has also highlighted in the scientific community the problem of people’s exposure to outdoor and indoor pollution, confirmed as a key element for the increase both in the transmission and severity of the contagion, on top of involving health risks on their own. In this context, most nations are going to adopt new preferential policies to stimulate the development of relevant sustainable energy industries, based on the electrification of the systems supplied by renewable energy sources as confirmed by the International Energy Agency (IEA). Thus, while there is ongoing research focusing on a COVID 19 vaccine, there is also a need for researchers to work cooperatively on novel strategies for world economic recovery incorporating renewable energy policy, technology and management. In this framework, the Sustainable Development of Energy, Water and Environment Systems (SDEWES) conference provides a good platform for researchers and other experts to exchange their academic thoughts, promoting the development and improvements on the renewable energy technologies as well as their role in systems and in the transition towards sustainable energy systems. The 14th SDEWES Conference was held in Dubrovnik, Croatia. It brought together around 570 researchers from 55 countries in the field of sustainable development. The present Special Issue of Energies, specifically dedicated to the 14th SDEWES Conference, focuses on four main fields: energy policy for sustainable development, biomass energy application, building energy saving, and power plant and electric systems.

“…For a theoretical facility such as this one, a number of key assumptions must be made in regards to the finances and set up (38)(39)(40)(41). Parameters such as contingency, maintenance budget, depreciation schedule, discount rate and construction period were all taken as the average values used within the literature, as shown in ha -1 ) and electricity (£ kWh -1 ) were calculated as the average values for these in the UK (42,43).…”
