A Review of the Role of Critical Parameters in the Design and Operation of Biogas Production Plants
Sarker, Shiplu; Lamb, Jacob Joseph; Hjelme, Dag Roar; Lien, Kristian Myklebust (Journal article; Peer reviewed, 2019)Many operating parameters, individually or together, may influence the performance of anaerobic digestion towards biogas or digestate yield and quality maximization. The most preferred method of optimizing an anaerobic ... -
Carbohydrate Yield and Biomethane Potential from Enzymatically Hydrolysed Saccharina latissima and Its Industrial Potential
Lamb, Jacob Joseph; Hjelme, Dag Roar; Lien, Kristian Myklebust (Journal article; Peer reviewed, 2019)The demand for fuel for utilisation of machinery and transport has culminated in large amounts of fossil fuel usage in the last century. The environmental dangers attached with the usage of fossil fuels have created a large ... -
Cryogenic vs. absorption biogas upgrading in liquefied biomethane production – An energy efficiency analysis
Hashemi, Sayed Ebrahim; Sarker, Shiplu; Lien, Kristian Myklebust; Schnell, Sondre Kvalvåg; Austbø, Bjørn (Journal article; Peer reviewed, 2019)Production of liquefied biomethane (LBM) from biogas comprises two major energy intensive processes; upgrading to increase the methane concentration and refrigeration to liquefy the upgraded biogas. Amine-based absorption ... -
Digitalization of colourimetric sensor arrays for volatile fatty acid detection in anaerobic digestion
Lamb, Jacob Joseph; Lien, Kristian Myklebust; Hjelme, Dag Roar (Journal article; Peer reviewed, 2019)During the process of converting the organic matter into methane, many volatile fatty acids (VFAs) are produced during acidogenesis and acetogenesis phases of the process. The main VFAs of interest are acetic acid, butyric ... -
Effect of power ultrasound and Fenton reagents on the biomethane potential from steam-exploded birchwood
Lamb, Jacob Joseph; Islam, Md Hujjatul; Hjelme, Dag Roar; Pollet, Bruno; Lien, Kristian Myklebust (Journal article; Peer reviewed, 2019)The global demand for non-fossil energy sources is increasing rapidly. As a result, biogas presents a suitable alternative; however, first generation biofuels (e.g., sugar cane) potentially impact food crops globally. ... -
Greenhouse gas balances in Zero Emission Buildings – Electricity conversion factors revisited
Andresen, Inger; Lien, Kristian Myklebust; Berker, Thomas; Sartori, Igor (ZEB Project report;, Research report, 2017) -
Opportunities and challenges for thermally driven hydrogen production using reverse electrodialysis system
Raka, Yash Dharmendra; Karoliussen, Håvard; Lien, Kristian Myklebust; Burheim, Odne Stokke (Journal article; Peer reviewed, 2019)Ongoing and emerging renewable energy technologies mainly produce electric energy and intermittent power. As the energy economy relies on banking energy, there is a rising need for chemically stored energy. We propose heat ... -
Optimization of an Absorption-Based Biogas Upgrading and Liquefaction Process
Hashemi, Sayed Ebrahim; Lien, Kristian Myklebust; Schnell, Sondre Kvalvåg; Austbø, Bjørn (Journal article; Peer reviewed, 2019)The present work proposes a methodology for optimization of a liquefied biomethane (LBM) production plant. The LBM production plant comprises amine-based absorption upgrading followed by a single expander refrigeration ... -
Overview of recent progress towards in-situ biogas upgradation techniques
Sarker, Shiplu; Lamb, Jacob Joseph; Hjelme, Dag Roar; Lien, Kristian Myklebust (Journal article; Peer reviewed, 2018)Biogas, as derived from the anaerobic digestion process, offers a versatile possibility of renewable and sustainable energy usage. When enriched, upgraded biogas can yield high levels of biomethane, allowing its use as an ... -
Perspectives of optical colourimetric sensors for anaerobic digestion
Lamb, Jacob Joseph; Bernard, Olivier; Sarker, Shiplu; Lien, Kristian Myklebust; Hjelme, Dag Roar (Journal article; Peer reviewed, 2019)Although biogas is not a new approach to producing renewable fuel, it could further be developed to improve its potential as an alternative energy source. To achieve this, vast improvements in the efficiency and cost of ... -
Perspectives of surface plasmon resonance sensors for optimized biogas methanation
Lamb, Jacob Joseph; Bernard, Olivier; Sarker, Shiplu; Lien, Kristian Myklebust; Hjelme, Dag Roar (Journal article; Peer reviewed, 2019)Biogas production is becoming significantly viable as an energy source for replacing fossil‐based fuels. The further development of the biogas production process could lead to significant improvements in its potential. ...
