Thermodynamic analysis of a novel fossil-fuel–free energy storage system with a trans-critical carbon dioxide cycle and heat pump [PDF]
, 2020 This paper presents and analyzes a novel fossil-fuel–free trans-critical energy storage system that uses CO2 as the working fluid in a closed loop shuttled between two saline aquifers or caverns at different depths: one a low-pressure reservoir and the ...

Biotechnology and Bioengineering, EarlyView.ABSTRACT Cultivating hydrogen‐oxidizing bacteria (HOB), such as Cupriavidus necator, using H 2 ${{\rm{H}}}_{2}$, CO 2 ${\text{CO}}_{2}$, and O 2 ${{\rm{O}}}_{2}$ offers a promising route for CO 2 ${\text{CO}}_{2}$ valorization into chemicals and materials. To enhance cultivation efficiency in a lab‐scale gas fermenter lacking a gas recycling system, an

Fuel quality-processing study. Volume 2: Literature survey [PDF]
The validity of initial assumptions about raw materials choices and relevant upgrading processing options was confirmed. The literature survey also served to define the on-site (at the turbine location) options for fuel treatment and exhaust gas ...

Biotechnology and Bioengineering, EarlyView.We show that pH and neutralization strategy strongly influence the growth, pellet morphology, and organic acid production of Aspergillus oryzae. Acidic and alkaline conditions lead to hairy, dispersed pellets, while near‐neutral environments favour compact pellet formation.

German wind power sector in crisis Energiewende under further threat. OSW COMMENTARY NUMBER 309 | 25.09.2019 [PDF]
, 2019 The slowdown in expansion of onshore wind farms poses a serious threat to the German Energiewende. In 2018, wind power accounted for half of the electricity obtained from RES, and is considered the driving force behind the Energiewende. In the first half

Business Strategy and the Environment, EarlyView.ABSTRACT This study adopted a mixed‐method approach to examine decarbonization business models/strategies employed across the energy ecosystem. In study 1, we conducted a systematic literature review of 94 studies to identify business models/strategies mapped to five energy ecosystem contexts—energy systems' transition, energy systems—demand side ...

Review of Passive Flow Control Methods for Compressor Linear Cascades
Applied SciencesThis paper reviews the evolution of flow control methods for bladed linear cascades, focusing on passive techniques like riblets, grooves, vortex generators (VGs), and blade slots, which have proven effective in reducing drag, suppressing flow separation,
