Henry's law and accumulation of weak source for crust-derived helium: A case study of Weihe Basin, China

open access: yesJournal of Natural Gas Geoscience, 2017
Crust-derived helium is generated from the radioactive decay of uranium, thorium and other radioactive elements in geological bodies. Compared with conventional natural gas, helium is a typical weak source gas as a result of extremely slow generation ...

Do Banks in the Middle East and North Africa Region Price Carbon Exposure?

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT This study examines whether carbon exposure is incorporated into corporate borrowing costs within the Middle East and North Africa (MENA) region. Using a panel of 771 firm‐year observations from publicly listed non‐financial firms between 2016 and 2023, the analysis investigates the relationship between carbon intensity and firms' cost of debt

Air Pollution, Investor Attention, and Greenium: An Attention‐Based View

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Although prior research has highlighted the growing importance of green bonds and their sensitivity to environmental conditions, evidence regarding the existence of a green‐bond premium (“greenium”) remains inconclusive. As an innovative financial instrument whose valuation depends partly on the credibility of its environmental certification ...

Tandem Electrolysers for High‐Efficiency CO2‐to‐Acetate Conversion Driven by Full‐Spectrum Solar Energy

open access: yesCarbon Energy, EarlyView.
A full‐spectrum solar‐driven tandem electrolysis system enables efficient CO2‐to‐acetate conversion by spectrally splitting sunlight and coupling high‐temperature SOEC CO2‐to‐CO electrolysis with ambient CO reduction. The integrated design achieves a solar‐to‐acetate efficiency of 15.8%, demonstrating effective energy‐quality matching for solar carbon ...
