Climate balance of biogas upgrading systems
Waste Management, 2010One of the numerous applications of renewable energy is represented by the use of upgraded biogas where needed by feeding into the gas grid. The aim of the present study was to identify an upgrading scenario featuring minimum overall GHG emissions. The study was based on a life-cycle approach taking into account also GHG emissions resulting from plant ...

Life cycle assessment of biogas upgrading technologies
Waste Management, 2012This article evaluates the life cycle assessment (LCA) of three biogas upgrading technologies. An in-depth study and evaluation was conducted on high pressure water scrubbing (HPWS), as well as alkaline with regeneration (AwR) and bottom ash upgrading (BABIU), which additionally offer carbon storage.

Upgrading Biogas to Biomethane
2020Biogas provides a flexible clean and efficient form of energy. Enriched biogas may generate large volumes of bioCH4, allowing its usage as an alternative to natural gas via existing natural gas networks or being used directly as fuel by vehicles. There are two broad categories of upgrade techniques where traditional methods focus on ex-situ upgrading ...

Biogas upgrading by cryogenic techniques
Environmental Chemistry Letters, 2019The scarcity of fossil fuels and the worldwide pollution have led the scientific community to seek renewable energy alternatives. In particular, biogas has become a potential alternative fuel to be employed instead of traditional energies. Biogas is mainly composed by methane (CH4) and carbon dioxide (CO2).

Biogas Purification and Upgrading Technologies
2018The fact that most countries do not promote the use of biogas as energy vector via tax incentives entails the need for an optimization of biogas upgrading technologies in order to support a cost-competitive utilization of this renewable energy source. Nowadays, the contaminants present in biogas such as CO2, H2S, H2O, N2, O2, siloxanes, and halocarbons

Biogas upgrading for dairy digesters
Biogas generated from the anaerobic digestion (AD) of livestock manure is a reliable source of renewable energy and is most commonly used to generate electricity. In more recent years, biogas has increasingly been refined and used as a “drop in” fuel to replace natural gas in transportation applications.Bronstad, Embrey +4 more
