The article discusses the development of membranes for carbon dioxide removal from industrial emissions, inspired by VHS tapes made of the same material, cellulose acetate. Gas separation membranes were limited to research centers for most of the 20th century, but polymeric membranes have emerged as a leading option for carbon dioxide separation due to their flexible molecular structure.

The U.S. Environmental Protection Agency (EPA) has committed to updating regulations for how landfills monitor, capture, and control methane emissions. The EPA is collecting information on new technologies and approaches that could be incorporated into updated rules for municipal solid waste (MSW) landfills. The agency is working on a series of white papers to inform the proposed regulations, covering topics such as gas capture systems, aerial monitoring for methane, and incentivizing organics diversion. The new rules are expected to be issued in 2025. [Extracted from the article]

The U.S. EPA has developed a Waste Characterization Handbook and Excel tool to assist decision-makers and solid waste professionals in conducting waste characterization studies. The Handbook provides guidance on planning and conducting these studies, as well as analyzing the data collected. The accompanying Excel tool allows for easy data entry and visualization. The resulting data can be used in other tools to better understand organic waste management and methane mitigation options. [Extracted from the article]

The article offers information on the ways to store renewable electricity. Topics discussed include conversion of renewable electricity into hydrogen, methane or ammonia fuels; aims of various former U.S. presidents such as John F. Kennedy regarding fueling paradigm for American automobiles; and development of automobiles powered by hydrogen and pollution free.

The article discusses the pipeline standards for biomethane and the issues in injecting Renewable Natural Gas (RNG) into the existing natural gas pipelines. Topics include the markets for low carbon vehicle fuels, energy policies on renewable electricity production, and biogas terminology are mentioned. Comments by Bernard Sheff owner of Sheff & Sons Engineering, Anthony LaRusso, principal program manager for Emerging Gas at electricity company National Grid are given.

The article discusses the use of biomethane or renewable natural gas (RNG) as vehicle fuel in Canada. Topics discussed include the Feed-in Tariff (FIT) program for biogas, production of biogas at Woodward Avenue wastewater treatment plant in Hamilton, Ontario and the role of municipal government in operating or administering vehicle fleets such as garbage trucks and transit buses. It also adds that RNG would be upgraded by biogas produced at Bio-En's Elmira anaerobic digester facility.

The article informs that by late June 2021, the U.S. Congress may finish its rollback of former President Donald Trump's removal of methane gas release from federal clean air regulation.

The article discusses the story on hydrogen which has always had two sides, and H2 does not produce carbon dioxide when it's burned in an enqine or reacted in a fuel cell. It mentions that the fuel is light, efficient to use, and a remarkable building block for chemicals or products that makes it an excellent alternative for petroleum or fossil methane gas as a fuel or feedstock.

The article discusses the city of Aberdeen, located on the Northeast coast of Scotland, UK, looks out to sea deep below the waves of the infamously hostile North Sea, oil has found. Topics include the ‘black gold' formed the basis of decades of prosperity turning to the offshore oil industry's capital; and Aberdeen's population has 230,000 and the city has a dynamic blend of modern and traditional the oil sector, extremely important.

Hydrogen is utilized by city buses Food Waste AD Facility Supplies Municipal Energy Demand: Anaerobic digestion plant supplies biomethane to energy center with dedicated CHP system that powers event center and a hydrogen reformer. The remaining biomethane is directed to the TECA events venue and energy center, which has a dedicated CHP system that generates heat for the buildings and powers a hydrogen reformer.

The article focuses on a research by researchers Rahul Banerjee and John D. Lipscomb from University of Minnesota, Twin Cities and Yegor Proshlyakov and Denis A. Proshlyakov of Michigan State University on ways of converting waste Compound Q methane into a liquid fuel and chemical feedstock.

A letter to the editor is presented in response to the article "Chasing Methane" that was published in the September 30, 2013 issue.
