“…Transitioning to a sustainable carbon cycle will require a suite of technologies from large‐scale carbon capture plants to a large number of small and distributed carbon capture units. [ 16 ] Inspired by the trend of individual responsibility, small and mobile carbon capture units could enable small business enterprises to play their part in reducing global carbon emissions. Recycling carbon dioxide from the air can be a valuable process in beverage carbonation, food preservation, and dry ice cleaning devices.…”

the viability of existing fossil fuel energy sources and processes. A more recent approach proposes the use of DAC [3] to complement the implementation of renewable energy sources in order to facilitate a reduction in global atmospheric CO 2 concentrations. In addition to new processes reported for CO 2 capture from stationary sources, such as the metal-mediated CO 2regenerative amine-based battery process that directly converts CO 2 reaction enthalpy into electrical energy, [4] DAC offers a practical mitigation of CO 2 emissions from highly distributed or mobile point sources. As an alternative to storage of captured CO 2 in deep saline aquifers suggested for large stationary emitting sources, [5] DACproduced CO 2 could be used as a chemical feedstock for the synthesis of value added products. [6,3b,7] Examples of such demonstrated technologies include the use of CO 2 instead of water to cure concrete leading to permanent sequestration of the CO 2 , [8] efficient growth of plants in greenhouses, and conversion of CO 2 into alcohols by algae. [3b,9] Additionally, the uptake of distributed point-of-use DAC CO 2 could mirror, and even be facilitated by, consumer-driven selection of point-of-use solar photovoltaics (PV) electricity generation and storage. [1a,10] Proposed routes for DAC include the use of aqueous basic solutions [11] and solid adsorbents [12] as capture media. Aqueous basic solutions are used because they offer the opportunity to continuously contact the feed air with the solution in the presence of contaminants and other constituents in the air. [13] From a process engineering perspective, this approach is excellent for large-scale carbon capture in the form of a processing plant permanently located alongside free waste-heat sources, such as a coal or gas power plant. [13c,d,14] Solid adsorbents offer the prospect of DAC with a low energy input, low operating costs, minimal infrastructure, and the potential for application over a broad range of scales. [14a,15] Transitioning to a sustainable carbon cycle will require a suite of technologies from large-scale carbon capture plants to a large number of small and distributed carbon capture units. [16] Inspired by the trend of individual responsibility, small and mobile carbon capture units could enable small business enterprises to play their part in reducing global carbon emissions. Recycling carbon dioxide from the air can be a valuable process in beverage carbonation, food preservation, and dry ice cleaning devices. [17] However, if small mobile DAC units relying solely on It is increasingly apparent that negative emissions technologies, such as direct air capture (DAC), are required as part of the technology mix for limiting global atmospheric temperature increase. For all DAC technologies, the requisite energy for regeneration of the separation media strongly influences the overall cost of the process and therefore directly influences their likely implementation. Herein, the results of a pilot-scale demonstration of a new metal organic framework (...

“…By contrast, the main benefit of thermal decomposition of methane in comparison with water electrolysis is the feedstock availability via the current natural gas infrastructure, whereas electrolysis is highly dependent on the cost and availability of renewable electricity. For power generation, Abanades examined two cases to illustrate the potential application of decarbonization in the power-to-gas scenario, considering a combined cycle plant [84]. Even if hydrogen were to be cheaper due to the higher scale, the plant's efficiency reduction to 34% is only compensated by carbon taxes of between 51 and 105 EUR/ton CO 2 .…”

Thermo-catalytic decomposition is well-suited for the generation of hydrogen from natural gas. In a decarbonization process for fossil fuel—pre-combustion—solid carbon is produced, with potential commercial uses including energy storage. Metal catalysts have the disadvantages of coking and deactivation, whereas carbon materials as catalysts offer resistance to deactivation and poisoning. Many forms of carbon have been tested with varied characterization techniques providing insights into the catalyzed carbon deposition. The breadth of studies testing carbon materials motivated this review. Thermocatalytic decomposition (TCD) rates and active duration vary widely across carbons tested. Regeneration remains rarely investigated but does appear necessary in a cyclic TCD–partial oxidation sequence. Presently, studies making fundamental connections between active sites and deposit nanostructures are few.

Future energy systems will comprise 100% renewable energy and involve high integration of energy systems. District heating (DH) and cooling systems will be an undeniable part of future energy systems, as they facilitate high-efficiency, low-cost, and clean production. Low-temperature district heating (LTDH) is one of the candidates for future district heating systems, where the supply temperature is 60°C or below. Reducing heat losses from the pipe network in DH systems is challenging. Improving the insulation standards in DH pipes can decrease heat and temperature losses in the pipe networks. This study employs computational fluid dynamics to evaluate the optimum insulation thickness based on the material and digging costs in South Korea. A micro hybrid DH system with natural gas run fuel cell, heat pump and solar thermal is proposed in this study. An evaluation of the system with a 500 m pipe network system supplying hot water at 60°C with polyethylene, ethylene propylene diene monomer rubber, and polyurethane as insulation materials using ANSYS Fluent 17.2 shows that the heat losses are minimal when using PU foams. A cost estimation analysis showed that 32 mm was the optimum insulation thickness for achieving heat losses below 20 W/m and minimum material and digging costs when burring the pipeline network in the ground.
