Who pays? Who cuts emissions? 5 issues for UN climate deal

by Associated Press  (Feb. 12, 2015)

World governments are hoping that this year will mark a breakthrough in the slow-paced U.N. climate talks. In Geneva this week, negotiators from more than 190 countries are working on a draft of a deal that's supposed to be adopted in Paris in December. At this point it's a wish list reflecting the diverging preferences of rich countries like the ...

Hexavalent chromium reduction and energy recovery by using dual-chambered microbial fuel cell

by IWA Publishing  (Feb. 26, 2015)

Microbial fuel cell (MFC) technology is utilized to treat hexavalent chromium (Cr(VI)) from wastewater and to generate electricity simultaneously. The Cr(VI) is bioelectrochemically reduced to non-toxic Cr(III) form in the presence of an organic electron donor in a dual-chambered MFC. The Cr(VI) as catholyte and artificial wastewater inoculated ...

Removal of bromide and bromate from drinking water using granular activated carbon

by IWA Publishing  (Feb. 27, 2015)

Granular activated carbon (GAC) was used to remove bromide (Br−) and bromate (BrO3−) from drinking water in both bench- and pilot-scale experiments. The present study aims to minimize BrO3− formation and eliminate BrO3− generated during the ozonation of drinking water, particularly in packaged drinking ...

Development and testing of a European Union –wide farm‐level carbon calculator

by John Wiley & Sons, Ltd.  (Feb. 6, 2015)

Direct greenhouse gas (GHG) emissions from agriculture accounted for around 10% of total European Union (EU) emissions in 2010. To reduce farming‐related GHG emissions, appropriate policy measures and supporting tools for promoting low‐carbon farming practices may be efficacious. This paper presents the methodology and testing results of a new ...

Comparative study on electrochemical 4-chlorophenol degradation in different diaphragm systems with combined reduction and oxidation properties

by IWA Publishing  (Jan. 21, 2015)

Two diaphragm electrolysis systems, two-electrode (anode–cathode) and three-electrode (cathode–anode–cathode), were compared for the electrochemical degradation of 4-chlorophenol. The performance of these systems was improved by feeding with hydrogen gas and then with air, in aid of the combined processes of reduction and ...

Impact of ambient air temperature and injection timing on reduction of engine out emissions of DI diesel engine operating under the influence of oxygen enriched hydrogen gas

by Inderscience Publishers  (Jan. 20, 2015)

The present experimental work is a study of the impact of ambient air temperature and the injection timing of diesel fuel on reduction of engine–out emissions of DI diesel engine, operating under the influence of oxygen enriched hydrogen gas. Here the oxygen enriched hydrogen gas was produced by the process of water electrolysis. The produced gas ...

Case study - Using thermal storage systems to reduce carbon emissions

by Climate-KIC  (Jan. 23, 2015)

Aquifer Thermal Energy Storage (ATES) systems have the potential to provide a significant tool for climate change mitigation. Using aquifers as a source for thermal energy can provide heating and cooling for houses, offices and other buildings E-USE (aq). In comparison to the use of fossil fuels, as well as providing up to 60% CO2 reductions, ...

Determinants of corporate carbon reduction targets

by Inderscience Publishers  (Sep. 25, 2014)

This paper examines attributes affecting a corporation’s choice of an intensity-only (carbon emissions relative to sales, production, etc.) versus an absolute carbon dioxide (CO 2 ) emissions goal. We investigate alternative hypotheses for this choice including: 1) a high growth hypothesis whereby high growth companies select an intensity goal, ...

The jobs impact of GHG reduction strategies in the USA

by Inderscience Publishers  (Dec. 2, 2014)

This paper estimates the economic and jobs impact of the USA displacing 1.2 billion tons of carbon emissions annually by 2030 using energy efficiency and renewable energy. We assess the technologies deployed, their costs, and the necessary time frames. We then estimate the job impacts of the policy and find that it will generate more than 4.5 ...

Carbon dioxide gas case study

by Ametek Process Instruments - THERMOX  (Nov. 24, 2014)

Application Moisture] is measured in carbon dioxide gas pipelines and processing plants. Problem The presence of moisture in carbon dioxide gas promotes corrosion. Perhaps more significant is the fact that moisture will readily form ice when pressure is reduced. The ice can readily freeze up pressure regulators, valves, and orifice plates causing ...
