Advances in metrology for energy-containing Gases and emerging demands
Metrologia, 2020Co-Authors: Adriaan M H Van Der Veen, Gerard Nieuwenkamp, Ewelina T Zalewska, Iris De Krom, Stefan Persijn, Heleen MeuzelaarAbstract:Metrological services from National Metrology Institutes related to energy Gases have been supported by the programme of key comparisons of the Gas Analysis Working Group of the Consultative Committee for Amount of Substance: Metrology in Chemistry and Biology since its conception in 1993. Most of the key comparisons have been performed on Natural Gas composition measurement, which is key to the calculation of Natural Gas properties, thereby facilitating fiscal metering and the trade in Natural Gas. In the recent years, non-conventional energy Gases and Natural Gas Substitutes, such as refinery Gas and bioGas have been addressed. The paper gives an overview over the achievements in this area from the first key comparison (CCQM-K1) onward and outlines the current challenges to the metrological community. The ongoing energy transition towards renewable energy Gases is at the centre of these challenges. The associated emerging challenges primarily concern the measurement of the concentrations of impurities, such as silicon in biomethane and upgraded bioGas, carbon monoxide in hydrogen, and many others. The paper presents the first results of the development of measurement standards and methods for impurities in bioGas, biomethane and hydrogen and the implications for the programme of key comparisons.

Prediction of burn rate, knocking and cycle-to-cycle variations of binary compressed Natural Gas Substitutes in consideration of reaction kinetics influences:
International Journal of Engine Research, 2017Co-Authors: Sebastian Hann, Lukas Urban, Michael Grill, Michael BargendeAbstract:Since zero-dimensional/one-dimensional simulations of Natural Gas spark-ignition engines use model theories similar to Gasoline engines, the impact of changing fuel characteristics needs to be take...

Techno-economic assessment of biomass-based Natural Gas Substitutes against the background of the EU 2018 renewable energy directive
Biomass Conversion and Biorefinery, 2018Co-Authors: Michael Kraussler, Florian Pontzen, Matthias Müller-hagedorn, Leopold Nenning, Markus Luisser, Hermann HofbauerAbstract:This paper investigates biomethane and BioSNG production processes against the background of the 2018 renewable fuel directive of the European Union (EU). The investigated biomethane processes use manure, clover grass, and grass silage as feedstock, are based on membrane separation Gas upgrading processes, and generate 1.0 and 4.8 MW of biomethane. The investigated BioSNG processes use wood chips as feedstock, are based on the dual fluidized bed steam Gasification technology and the VESTA SNG process from Amec Foster Wheeler, and generate 6.1, 12.2, and 49.1 MW BioSNG. The techno-economic assessment shows that the biomethane processes have, in general, a lower break-even price for the generated Natural Gas substitute. However, their scalability is limited and at larger scale (49.1 MW BioSNG capacity), the BioSNG processes become competitive. The 1.0 MW biomethane and all BioSNG plants meet the 2018 renewable fuel directive of the EU. In contrast, the 4.8 MW biomethane process does not meet the directive as the feedstock, which is mainly based on energy crops, causes significant CH_4 and CO_2 emissions.
