How green is blue hydrogen? Tập 9 Số 10 - Trang 1676-1687 - 2021
Robert W. Howarth, Mark Z. Jacobson
AbstractHydrogen is often viewed as an important energy carrier in a future
decarbonized world. Currently, most hydrogen is produced by steam reforming of
methane in natural gas (“gray hydrogen”), with high carbon dioxide emissions.
Increasingly, many propose using carbon capture and storage to reduce these
emissions, producing so‐called “blue hydrogen,” frequently promoted as low
emissions. We un... hiện toàn bộ
Advances on waste valorization: new horizons for a more sustainable society Tập 1 Số 2 - Trang 53-71 - 2013
Rick Arneil D. Arancon, Carol Sze Ki Lin, King Ming Chan, Tsz Him Kwan, Rafael Luque
AbstractIncreasingly tighter regulations regarding organic waste, and the demand
for renewable chemicals and fuels, are pushing the manufacturing industry toward
higher sustainability to improve cost‐effectiveness and meet customers’ demand.
Food waste valorization is one of the current research areas that has attracted
a great deal of attention over the past few years as a potential alternative t... hiện toàn bộ
Parametric analysis and systems design of dynamic photovoltaic shading modules Tập 4 Số 2 - Trang 134-152 - 2016
Johannes Hofer, Abel Groenewolt, Prageeth Jayathissa, Zoltán Nagy, Arno Schlueter
AbstractShading systems improve building energy performance and occupant comfort
by controlling glare, natural lighting, and solar gain. Integrating PV
(photovoltaics) in shading systems opens new opportunities for BIPV (building
integrated photovoltaics) on façades. A key problem of such systems is mutual
shading among PV modules as it can lead to electrical mismatch losses and
overheating effect... hiện toàn bộ
Enhanced oil recovery mechanism and recovery performance of micro‐gel particle suspensions by microfluidic experiments Tập 8 Số 4 - Trang 986-998 - 2020
Wenhai Lei, Tong Liu, Chiyu Xie, Haien Yang, Tianjiang Wu, Moran Wang
AbstractMicro‐gel particle suspensions (MGPS) have been proposed for enhanced
oil recovery (EOR) in reservoirs with harsh conditions in recent years, yet the
mechanisms are still not clear because of the complex property of MGPS and the
complex geometry of rocks. In this paper, the micro‐gel particle‐based flooding
has been studied by our microfluidic experiments on both bi‐permeability
micromodel... hiện toàn bộ
Numerical investigation of casing shear deformation due to fracture/fault slip during hydraulic fracturing Tập 8 Số 10 - Trang 3588-3601 - 2020
Hu Meng, Hongkui Ge, Fu DengWei, Xiaoqiong Wang, Yinghao Shen, Zhenxin Jiang, Jianbo Wang
AbstractThe frequent occurrence of casing failure has significantly affected the
development of shale gas in the Sichuan Basin. Based on engineering and geology
analyses, natural fracture/fault slip leads to casing shear deformation during
hydraulic fracturing. Hence, natural fracture/fault slip and casing‐cement
sheath‐formation assembly finite element models were established to
quantitatively ex... hiện toàn bộ
Characteristics of energy storage and dissipation of coal under one‐time cyclic load Tập 8 Số 9 - Trang 3117-3135 - 2020
Kang Peng, Shaowei Shi, Quanle Zou, Junhui Mou, Jin Yu, Yongjiang Zhang, Yanying Cheng
AbstractEnergy is an important research parameter in rock mechanics. To explore
the law of energy evolution of coal, a one‐time loading and unloading test under
uniaxial compression was conducted on coal taken from four different coal mines.
By utilizing the area integral method, the total input, elastic, and dissipated
energy densities in coal at different unloading levels were calculated. The

Spectral response measurements of multijunction solar cells with low shunt resistance and breakdown voltages Tập 4 Số 6 - Trang 372-382 - 2016
Juan Pablo Babaro, Kevin G. West, Behrang H. Hamadani
AbstractSpectral response measurements of germanium‐based triple‐junction solar
cells were performed under a variety of light and voltage bias conditions. Two
of the three junctions exhibited voltage and light bias‐dependent artifacts in
their measured responses, complicating the true spectral response of these
junctions. To obtain more insight into the observed phenomena, a set of
current‐voltage... hiện toàn bộ
