The earth's temperature and climate are being affected by human activities that involve burning of fossil fuels the clearing forests, which release greenhouse gases, like carbon dioxide (CO2). These fuels, include coal oil, made was first taken from atmosphere photosynthesis millions years ago. combustion these is making up >75% gas emissions worldwide almost 90% CO2 overall. Additionally, Global Carbon Budget 2022 estimates yearly have grown every decade since mid-twentieth century, about 11 billion tons in 1960s to a 36.6 2022. Therefore, capture utilization (CCU) considered an important mitigation strategy support compliment storage (CCS) objectives for reduction CO2. geological (geo-storage) promising approach can help reduce emissions. However, effective underground formations requires understanding main techniques trapping mechanisms. more research required enhance understand their underlying mechanics. In light this, this investigates many oceanic geo-storage techniques, such as saline aquifers, depleted oil reservoirs, unmineable seams, basalt formations, hydrates. stability its mechanisms major areas interest. Physical chemical processes static, capillary, adsorption, solubility, mineral trapping, ionic exchange highlighted.

Hydrogen Storage Performance During Underground Hydrogen Storage in Depleted Gas Reservoirs: A Review

Engineering, Journal Year: 2024, Volume and Issue: 40, P. 211 - 225

Published: April 12, 2024

Hydrogen has emerged as a promising alternative to meet the growing demand for sustainable and renewable energy sources. Underground hydrogen storage (UHS) in depleted gas reservoirs holds significant potential large-scale seamless integration of intermittent sources, due its capacity address challenges associated with nature ensuring steady reliable supply. Leveraging existing infrastructure well-characterized geological formations, offer an attractive option implementation. However, knowledge gaps regarding performance hinder commercialization UHS operation. deliverability, trapping, equation state are key areas limited understanding. This literature review critically analyzes synthesizes research on during underground reservoirs; it then provides high-level risk assessment overview techno-economics UHS. The significance this lies consolidation current knowledge, highlighting unresolved issues proposing future research. Addressing these will advance hydrogen-based systems support transition landscape. Facilitating efficient safe deployment assist unlocking hydrogen's full clean carrier. In addition, aids policymakers scientific community making informed decisions technologies.

27.09%-efficiency silicon heterojunction back contact solar cell and going beyond

Nature Communications, Journal Year: 2024, Volume and Issue: 15(1)

Published: Oct. 16, 2024

Crystalline-silicon heterojunction back contact solar cells represent the forefront of photovoltaic technology, but encounter significant challenges in managing charge carrier recombination and transport to achieve high efficiency. In this study, we produced highly efficient with a certified efficiency 27.09% using laser patterning technique. Our findings indicate that losses primarily arise from hole-selective region polarity boundaries. We propose solutions these issues establish clear relationship between resistivity, series resistance, design rear-side pattern. Furthermore, demonstrate wafer edge becomes main channel for current density loss caused by once electrical shading around electron-selective is mitigated. With advanced nanocrystalline passivating contact, passivation technologies meticulous optimization front anti-reflection coating rear reflector, achieving efficiencies as 27.7% feasible.
