‘CLOSING THE CARBON LOOP’: Climate Policy Discourses and the Material Politics of Municipal Waste‐to‐Biofuel Programs

International Journal of Urban and Regional Research, EarlyView.
Abstract Waste‐to‐biofuel (WTB) programs have gained popularity as a municipal circular economy and an emissions reduction strategy. The upgrading of biofuels to renewable natural gas (RNG) has drawn particular interest, as RNG can displace conventional fossil fuels in any existing natural gas end use and be delivered through existing pipeline ...

Development of CCMb: A Low‐Mg Calcite Reference Material for In Situ Measurement of δ18O, δ13C and Selected Trace Elements

Geostandards and Geoanalytical Research, EarlyView.
Key Points Low‐Mg calcite RM developed for in situ microanalysis applications in palaeoclimatology (δ18O, δ13C; Mg, Sr m/m). New data for calcite CRM IAEA‐603 (δ18O, δ13C by SIMS and GS‐IRMS; Mg m/m). No detectable IMF effect of Mg on SIMS δ18O determinations for mass fractions < 3650 μg g‐1.

Numerical simulation of hydraulic fracture propagation after thermal shock in shale reservoir

Journal of Petroleum Exploration and Production Technology
The scale of propagation of hydraulic fractures in deep shale is closely related to the effect of stimulation. In general, the most common means of revealing hydraulic fracture propagation rules are laboratory hydraulic fracture physical simulation ...

Shale gas in Europe: much ado about little? Egmont Paper No. 64, March 2014 [PDF]

, 2014
Introduction. Shale gas is an unconventional form of gas1 because its extraction is more difficult or less economical than that of conventional natural gas.

Deep Groundwater Total Dissolved Solids Mapping in the Dakota Group, Williston Basin, USA

Groundwater, EarlyView.
Abstract Growing concern about the quantity of available freshwater around the world has led to interest in surveying groundwater total dissolved solids (TDS) below water well depths. Deep TDS has not been systematically mapped, and there is much to learn about the distribution and controls on deeper groundwater. In sedimentary basins across the United

Differences in the Media’s Framing of Fracking/Shale Gas in New York, Pennsylvania, Germany, and the United Kingdom [PDF]

Over the past decade, commercial mining firms in the United States have increasingly used horizontal drilling and hydraulic fracturing (fracking) to extract natural gas from shale rock formations (shale gas).

Carbon Populism and Representative Politics: On Why Fossil Fuel Firms Speaking for ‘The People’ Is a Bad Idea

Journal of Management Studies, EarlyView.
Abstract Despite growing recognition that countries around the world must transition to a low‐carbon economy, global greenhouse gas emissions continue to rise. One way that decarbonization has been obstructed, we argue, is by fossil fuel firms intentionally conflating their agenda with ‘the people’, evoking notions of national identity, security and ...

Elastic-wave-equation numerical simulation using a time–space domain dispersion-relation-based staggered-grid finite-difference method

Frontiers in Earth Science
Compared to the conventional high-order staggered-grid finite-difference method (C-SFD), the time–space domain dispersion-relation-based high-order staggered-grid finite-difference method (TS-SFD) can suppress the numerical dispersion more efficiently to
