“…The Life Cycle Inventory (LCI) was developed using both primary and secondary data. Primary data (input and output flows) for the main processes in the foreground system referring to the power plant construction and operation, that is, input materials flow at the construction of the wells, structures, machinery, and pipelines as well as those used in operation and maintenance phases and transportation stages were gathered from the various scientific publications relating to this plant [5,6,23,25,26]. Similarly, data regarding the energy consumption that is: consumption of diesel for wells drilling, internal use of electricity at the site and for drilling wells, and the composition of geothermal fluid represent primary data.…”

This study deals with the life cycle assessment (LCA) and an exergo-environmental analysis (EEvA) of the geothermal Power Plant of Hellisheiði (Iceland), a combined heat and power double flash plant, with an installed power of 303.3 MW for electricity and 133 MW for hot water. LCA approach is used to evaluate and analyse the environmental performance at the power plant global level. A more in-depth study is developed, at the power plant components level, through EEvA. The analysis employs existing published data with a realignment of the inventory to the latest data resource and compares the life cycle impacts of three methods (ILCD 2011 Midpoint, ReCiPe 2016 Midpoint-Endpoint, and CML-IA Baseline) for two different scenarios. In scenario 1, any emission abatement system is considered. In scenario 2, re-injection of CO2 and H2S is accounted for. The analysis identifies some major hot spots for the environmental power plant impacts, like acidification, particulate matter formation, ecosystem, and human toxicity, mainly caused by some specific sources. Finally, an exergo-environmental analysis allows indicating the wells as significant contributors of the environmental impact rate associated with the construction, Operation & Maintenance, and end of life stages and the HP condenser as the component with the highest environmental cost rate.

“…The options shown in Table 4 can retain acceptable costs while scaling for the safe sequestration of trillions of tonnes of liquid CO 2 produced by the HTL and Allam Cycle power plants. They include geologic CO 2 sequestration in depleted oil and gas wells and brine aquifers [59,127,128] and mineralization in olivine, basalt, and other rocks on land [8, [129][130][131][132][133] and in the sub-seafloor [134]. Other authors have analyzed secure contained seafloor storage either as liquid [135] or as CO 2 -hydrate [136][137][138].…”

“…6 With geologic or mineralization storage, the injection rate of CO 2 should not exceed that which causes earthquakes or leaks due to high pressure in the ground near the injection point [127]. 7 The actual mineralization rate depends on the characteristics of the local rocks [133,139]. See SMD for maps and discussion of different types of rocks with more references [132,134,140].…”

Unless humanity achieves United Nations Sustainable Development Goals (SDGs) by 2030 and restores the relatively stable climate of pre-industrial CO2 levels (as early as 2140), species extinctions, starvation, drought/floods, and violence will exacerbate mass migrations. This paper presents conceptual designs and techno-economic analyses to calculate sustainable limits for growing high-protein seafood and macroalgae-for-biofuel. We review the availability of wet solid waste and outline the mass balance of carbon and plant nutrients passing through a hydrothermal liquefaction process. The paper reviews the availability of dry solid waste and dry biomass for bioenergy with CO2 capture and storage (BECCS) while generating Allam Cycle electricity. Sufficient wet-waste biomass supports quickly building hydrothermal liquefaction facilities. Macroalgae-for-biofuel technology can be developed and straightforwardly implemented on SDG-achieving high protein seafood infrastructure. The analyses indicate a potential for (1) 0.5 billion tonnes/yr of seafood; (2) 20 million barrels/day of biofuel from solid waste; (3) more biocrude oil from macroalgae than current fossil oil; and (4) sequestration of 28 to 38 billion tonnes/yr of bio-CO2. Carbon dioxide removal (CDR) costs are between 25–33% of those for BECCS with pre-2019 technology or the projected cost of air-capture CDR.

“…Then, CO 2 from the flue gas is injected by the blower to the Ca(OH) 2 solution, resulting in a carbonation reaction. Carbon capture and storage (CCS) is considered the key technology for mitigating emissions from fossil-fuel power plants while these are still operational [3]. Much research has been carried out on how to store the carbon using various methods, such as geological sequestration [4,5], biological fixation [6,7], and ocean disposal [8,9].…”

This study introduces a novel methodology to calculate the carbon dioxide (CO2) emission reduction related to residual emissions, calculating the CO2 emission reduction through a 2 MW (40 tCO2/day) carbon capture and utilization (CCU) plant installed at a 500 MW coal-fired power plant in operation, to evaluate the accuracy, maintainability, and reliability of the quantified reduction. By applying the developed methodology to calculate the CO2 emission reduction, the established amount of CO2 reduction in the mineral carbonation was evaluated through recorded measurement and monitoring data of the 2 MW CCU plant at the operating coal-fired plant. To validate the reduction, the accuracy, reproducibility, consistency, and maintainability of the reduction should be secured, and based on these qualifications, it is necessary to evaluate the contribution rate of nationally determined contributions (NDCs) in each country. This fundamental study establishes the concept of CCU CO2 reduction and quantifies the reduction to obtain the validation of each country for the reduction. The established concept of the CCU in this study can also be applied to other CCU systems to calculate the reduction, thereby providing an opportunity for CCU technology to contribute to the NDCs in each country and invigorate the technology.
