"Kilang bio dengan carbon capture and storage memiliki potensi dalam mengurangi emisi karbon dari atmosfer. Penelitian ini bertujuan untuk memperoleh efisiensi energi keseluruhan sistem, biaya produksi (etanol, xilitol, dan listrik), CO2 avoidance cost (CAC), serta nilai emisi CO2eq dari integrasi sistem kilang bio dengan carbon capture and storage(CCS). Aspen Plus v.11 digunakan untuk simulasi proses produksi etanol dan xilitol dengan teknologi hidrolisis asam, sedangkan unit CCS disimulasikan dengan Aspen HYSYS v.11. Penelitian ini menggunakan dua skema, yaitu skema produksi tunggal etanol (1) dan skema koproduksi etanol-xilitol (2). Analisis lingkungan dilakukan dengan metode life cycle assessment (LCA) dengan lingkup cradle-to-gate dan analisis keekonomian dilakukan dengan metode levelized cost. Hasil penelitian menunjukkan bahwa efisiensi energi sistem keseluruhan  lebih tinggi pada skema 1 (35,8%) daripada skema 2 (33,7%). Nilai emisi sistem kilang bio dengan CCS pada skema 1 (-3,55 kgCO2eq/L etanol) lebih negatif daripada skema 2 (-2,20 kgCO2eq/L etanol). Skema 1 memiliki biaya produksi etanol dan nilai CAC (0,64 USD/L etanol dan 69,50 USD/ton CO2eq)  yang lebih besar daripada skema 2 (0,60 USD/L etanol dan 63,98 USD/ton CO2eq). Skema 1 menghasilkan nilai LCOE (0,15 USD/kWh) yang lebih tinggi daripada skema 2 (0,14 USD/kWh). Pada skema 2 diperoleh biaya produksi xilitol seharga 2,73 USD/kg xilitol. Oleh karena itu, skema 2 memiliki potensi komersial yang lebih baik.

Biorefinery with carbon capture and storage has great potential in reducing carbon emissions from the atmosphere. This study aims to obtain the overall system energy efficiency, production costs (ethanol, xylitol, and electricity), CO₂ avoidance cost (CAC), and CO2eq emission from the integration of biorefinery system with carbon capture and storage (CCS). Aspen Plus v.11 was used to simulate the ethanol and xylitol production processes using acid hydrolysis, while the CCS unit was simulated with Aspen HYSYS v.11. This study uses two schemes, namely a single ethanol production scheme (1) and an ethanol-xilitol coproduction scheme (2). Environmental analysis was conducted using the life cycle assessment (LCA) method with a cradle-to-gate scope, and economic analysis was conducted using the levelized cost method. The results showed that the overall system energy efficiency was higher in scheme 1 (35.8%) than scheme 2 (33.7%). The emission value of the biorefinery system with CCS in scheme 1 (-3.55 kgCO2eq/L ethanol) was more negative than scheme 2 (-2.20 kgCO2eq/L ethanol). Scheme 1 has higher ethanol production costs and CAC values (0.64 USD/L ethanol and 69.50 USD/ton CO2eq) than scheme 2 (0.60 USD/L ethanol and 63.98 USD/ton CO2eq). Scheme 1 produced a higher LCOE value (0.15 USD/kWh) than scheme 2 (0.14 USD/kWh). In scheme 2, the production cost of xylitol is 2.73 USD/kg xylitol. Therefore, scheme 2 has better commercial viability."

"This book approaches the energy science sub-field carbon capture with an interdisciplinary discussion based upon fundamental chemical concepts ranging from thermodynamics, combustion, kinetics, mass transfer, material properties, and the relationship between the chemistry and process of carbon capture technologies. Energy science itself is a broad field that spans many disciplines, policy, mathematics, physical chemistry, chemical engineering, geology, materials science and mineralogy, and the author has selected the material, as well as end-of-chapter problems and policy discussions, that provide the necessary tools to interested students."

"In this volume, summarize polyethylene glycol (PEG)-promoted CO2 chemistry on the basis of understanding about phase behavior of PEG/CO2 system and reaction mechanism at molecular level. Furthermore, they describe carbon capture and utilization strategy as an alternative approach to address the energy penalty problem in carbon capture and storage. The authors also discuss PEG radical chemistry in dense CO2 as rather creative and unusual use of PEG, presumably serves as a reaction medium and a radical initiator for radical chemistry."

"Paris Agreement merupakan perjanjian mengenai mitigasi emisi gas CO2. Tujuan perjanjian ini dibentuk untuk menahan laju peningkatan temperatur global. Hal ini juga didukung mengenai volume emisi CO2 akibat pembakaran bahan bakar fosil yang mencapai 56% dari total semua emisi global. Carbon Capture and Storage (CCS) adalah salah satu solusi di bidang teknologi mitigasi yang membahas pemanasan global. Penelitian ini bertujuan untuk mengidentifikasi dan menganalisis konduktivitas listrik pada sampel batuan tersaturasi CO2 yang didapatkan dari perhitungan Digital Rock Physics. Metode Digital Rock Physics adalah suatu metode berbasis digital yang memanfaatkan citra batuan digital untuk mengidentifikasi sifat fisis batuan dan visualisasi struktur mikro batuan secara lebih efektif dan efisien. Dengan memanfaat metode digital rock physics menggunakan sampel batuan pasir dan karbonat, dapat menunjukkan antara korelasi konduktivitas listrik terhadap batuan tersaturasi CO2 dengan konsentrasi 2 mg / L, 6.5 mg/L, dan 10 mg/L tiap saturasi CO2 mulai dari 0% hingga 100%. Hasil analisis menunjukkan nilai konduktivitas listrik sangat baik pada batuan pasir dengan rentang 1.38 μS/cm - 2.80 μS/cm dan batuan karbonat dengan rentang 18.38 μS/cm - 20.47 μS/cm. Hasil penelitian ini menunjukkan nilai konduktivitas listrik berbanding lurus dengan saturasi CO2. Hasil penelitian juga menunjukkan nilai porositas sangat baik pada batuan pasir dengan rentang 19.51% - 26.92% dan batuan karbonat 12.88% - 14.41%. Porositas juga mempengaruhi nilai konduktivitas listrik terhadap batuan tersaturasi CO2. Semakin besar nilai porositas, maka konduktivitas listrik akan semakin rendah. Konsentrasi CO2 juga mempengaruhi konduktivitas listrik, dimana semakin tinggi konsentrasi CO2 maka semakin besar nilai kondukstivitas listrik yang didapat. Hubungan antara konduktivitas listrik batuan dengan konsentrasi CO2 sangat kuat dengan koefisien korelasi diatas 0,9 untuk semua sampel. Berdasarkan hasil ini dapat digunakan sebagai salah satu parameter aplikasi Carbon Capture Storage (CCS) untuk mengetahui saturasi CO2 yang berada di dalam reservoir berdasarkan konduktivitas listrik batuan dengan catatan sebelumnya reservoir yang digunakan tidak ada fluida yang terisi dan tidak ada kompaksi tanah.

The Paris Agreement is an agreement on the mitigation of CO2 gas emissions. The purpose of this agreement was formed to restrain the rate of increase in global temperature. This is also supported by the volume of CO2 emissions due to the burning of fossil fuels, which account for 56% of all global emissions. Carbon Capture and Storage (CCS) is one of the solutions in the field of mitigation technology that addresses global warming. This study aims to identify and analyze the electrical conductivity of CO2 saturated rock samples obtained from Digital Rock Physics calculations. Digital Rock Physics method is a digital based method that utilizes digital rock images to identify rock physical properties and visualize rock microstructure more effectively and efficiently. By utilizing the digital rock physics method using sand and carbonate rock samples, it can show the correlation of electrical conductivity to CO2 saturated rocks with concentrations of 2 mg/L, 6.5 mg/L, and 10 mg/L per CO2 saturation ranging from 0% to 100%. The results of the analysis show that the electrical conductivity is very good in sandstone with a range of 1.38 μS/cm - 2.80 μS/cm and carbonate rocks with a range of 18.38 μS/cm - 20.47 μS/cm. The results of this study indicate the value of electrical conductivity is directly proportional to CO2 saturation. The results also showed very good porosity values in sandstone with a range of 19.51% - 26.92% and carbonate rock 12.88% - 14.41%. Porosity also affects the value of the electrical conductivity of CO2 saturated rocks. The greater the porosity value, the lower the electrical conductivity. The concentration of CO2 also affects the electrical conductivity, where the higher the concentration of CO2, the greater the value of the electrical conductivity obtained. The relationship between the electrical conductivity of rocks with CO2 concentration is very strong with a correlation coefficient above 0.9 for all samples. Based on these results, it can be used as one of the parameters for the application of Carbon Capture Storage (CCS) to determine the CO2 saturation in the reservoir based on the electrical conductivity of the rock with the previous record that the reservoir used was not filled with fluid and no soil compaction."

"Sleipner merupakan lapangan minyak dan gas pertama yang melakukan penginjeksian karbon dioksida untuk Carbon Capture and Storage (CCS). Penginjeksian ini pertama kali dilakukan pada tahun 1996. Penulis telah melakukan seismic monitoring dengan metode inversi model-based terhadap data tahun 1994 yang merupakan tahun sebelum injeksi karbon dioksida, serta tahun setelah injeksi karbon dioksida, yaitu tahun 2001 dan 2010. Hasil inversi pada tahun 1994, 2001, dan 2010 menunjukkan rentang impedansi akustik yang konsisten untuk shale, sedangkan bright spot menunjukkan adanya CO2 yang menyebabkan terjadinya penurunan nilai impedansi karena pengurangan kepadatan dan peningkatan kecepatan gelombang pada reservoir. Tidak ada kebocoran CO2 yang terdeteksi, dikarenakan keberadaan lapisan seal yang baik. Penginjeksian CO2 menyebabkan penurunan horizon Base Utsira sehingga membentuk seperti sinklin. Variasi impedansi akustik dipengaruhi oleh densitas CO2 yang lebih rendah daripada reservoir di zona saline aquifer. Temuan ini menggarisbawahi efektivitas CCS dan pentingnya teknik pemantauan yang kuat.

Sleipner is the first oil and gas field to perform carbon dioxide injection for Carbon Capture and Storage (CCS). This injection was first carried out in 1996. The author conducted seismic monitoring using the model-based inversion method for data from year 1994, which is the year before carbon dioxide injection, as well as in the years after carbon dioxide injection, namely 2001 and 2010. The inversion results for data from year 1994, 2001, and 2010 show a consistent range of acoustic impedance for shale, while bright spots indicate the presence of CO2, which causes a decrease in impedance values and density and increased wave velocity in the reservoir. No CO2 leakage was detected, due to the presence of a good seal layer. CO2 injection caused a decline in the Base Utsira horizon, forming a syncline-like. Variations in acoustic impedance are influenced by the lower density of CO2 compared to the reservoir in the saline aquifer zone. These findings underline the effectiveness of CCS and the importance of robust monitoring techniques."

"Carbon Capture and Storage, Second Edition, provides a thorough, non-specialist introduction to technologies aimed at reducing greenhouse gas emissions from burning fossil fuels during power generation and other energy-intensive industrial processes, such as steelmaking. Extensively revised and updated, this second edition provides detailed coverage of key carbon dioxide capture methods along with an examination of the most promising techniques for carbon storage. The book opens with an introductory section that provides background regarding the need to reduce greenhouse gas emissions, an overview of carbon capture and storage (CCS) technologies, and a primer in the fundamentals of power generation. The next chapters focus on key carbon capture technologies, including absorption, adsorption, and membrane-based systems, addressing their applications in both the power and non-power sectors. New for the second edition, a dedicated section on geological storage of carbon dioxide follows, with chapters addressing the relevant features, events, and processes (FEP) associated with this scenario. Non-geological storage methods such as ocean storage and storage in terrestrial ecosystems are the subject of the final group of chapters. A chapter on carbon dioxide transportation is also included. This extensively revised and expanded second edition will be a valuable resource for power plant engineers, chemical engineers, geological engineers, environmental engineers, and industrial engineers seeking a concise, yet authoritative one-volume overview of this field. Researchers, consultants, and policy makers entering this discipline also will benefit from this reference"

"This book describes comprehensively carbon (C) cycle process in global ecosystems and the potential and co-benefits of recarbonization of the biosphere. An ever increasing human population is disposing increasing amounts of carbon dioxide (CO2) into the atmosphere by land use and land cover changes but most importantly by burning of fossil fuels. This process severely perturbs the natural global C cycles and Earth system processes. Recarbonization of the biosphere is a potential strategy to redistribute C among global pools, and to enhance ocean but most importantly land-based C sinks. Sustainably managed and protected must be, in particular, the large and sensitive C stocks in permafrost, wetlands, peatlands, tropical rainforests and savannas, grasslands, degraded/desertified lands, and croplands. Recarbonization requires long-term management because C stocks grow with a progressive improvement in ecosystem health. Protecting and enhancing land-based C sinks serves food security aside contributing to climate change mitigation and adaptation. "

"Skripsi ini bertujuan untuk mengkaji formulasi kebijakan teknologi carbon capture, utilisation, and storage (CCUS) yang diatur melalui Peraturan Menteri ESDM No. 2 Tahun 2023 dan Peraturan Presiden No. 14 Tahun 2024. Di saat ini, dua regulasi yang hadir tersebut hanya mengatur penggunaan CCUS dalam industri migas secara eksklusif. Kelemahan terbesar yang ada merupakan ketidakhadiran dari insentif ekonomi yang diberikan pemerintah untuk kontraktor atau pelaku industri aktivitas CCUS. Dengan harga hingga USD$1 miliar per fasilitas, adopsi CCUS dengan regulasi yang ada sekarang memiliki lebih banyak resiko daripada keuntungan bagi pelaku industri yang relevan. Keberlanjutan teknologi CCUS di Indonesia juga menjadi pertanyaan mengingat peraturan yang ada tidak membahas penelitian domestik yang dapat mengembangkan CCUS lebih lanjut dan mempermudah adopsinya kedepan. Skripsi ini ingin menjawab mengapa Permen ESDM No. 2 Tahun 2023 dan Perpres No. 14 Tahun 2024 terbatas dalam formulasinya. Penelitian ini menggunakan metode kualitatif melalui wawancara dan studi literatur, dimana yang terkumpul akan dianalisis menggunakan teori Bounded Rationality milik Herbert Simon seperti yang dijelaskan oleh Bryan Jones. Keterbatasan yang ditemukan dalam proses perumusan kebijakan CCUS di Indonesia disebabkan oleh tiga faktor: 1) keterbatasan informasi akibat usia muda teknologi penangkapan karbon sehingga data lapangan yang tersedia cukup terbatas; 2) keterbatasan kognisi para pembuat kebijakan yang ditandai dengan ketidakmampuan mereka untuk sepenuhnya memahami kebutuhan, masalah, dan risiko yang mungkin terjadi dalam operasi CCUS; 3) keterbatasan waktu akibat keberadaan kepentingan Indonesia dalam pemenuhan janji-janji yang dibuat pada saat KTT G20 tahun 2022 dan peluang untuk menarik investasi sehingga para pembuat kebijakan mengeluarkan regulasi dalam waktu yang singkat. Kombinasi dari ketiga keterbatasan ini menyebabkan para pembuat kebijakan menghasilkan regulasi tidak optimal, dan hanya menghasilkan regulasi yang “cukup” (satisficing).

This thesis aims to examine the policy formulation of carbon capture, utilisation, and storage (CCUS) technology regulated through Permen ESDM No. 2 Tahun 2023 and Peraturan Presiden No. 14 Tahun 2024. Presently, the two existing regulations only control the use of CCUS in the oil and gas industry exclusively. The biggest drawback is the absence of economic incentives provided by the government for contractors or industry players of CCUS activities. Costing up to USD$1 billion per facility, the adoption of CCUS with the current regulations has more risks than benefits for the relevant industry players. The sustainability of CCUS technology in Indonesia is also questionable as the existing regulation does not address domestic research that could further develop CCUS and facilitate its future adoption. This thesis aims to answer why Permen ESDM No. 2 Tahun 2023 and Perpres No. 14 Tahun 2024 are limited in their formulation. This research uses qualitative methods through interviews and literature studies, wherein the data collected will be analysed using Herbert Simon's Bounded Rationality theory as explained by Bryan Jones. The limitations found in the CCUS policy formulation process in Indonesia are caused by three factors: 1) limited information due to the young age of carbon capture technology resulting in the limited available field; 2) limited cognition of policymakers characterised by their inability to fully understand the needs, problems, and risks that may occur in CCUS operations; 3) limited time due to the existence of Indonesia's interest in fulfilling the promises made during the G20 Summit in 2022 and the opportunity to attract investment caused the policymakers to issue regulations in a short time period. The combination of these three limitations causes policy makers to produce non-optimal regulations, and only produce "satisficing" regulations."
