Methane emissions from biogas plants – Methods for measurement, results and effect on greenhouse gas balance of electricity produced

IEA Bioenergy Webinar Series – 18 January 2018

Presented by Jan Liebetrau
Head of Biochemical Conversion Department
DBFZ; German Biomass Research Center

The webinar introduces the new report of IEA Bioenergy Task 37: “Methane emissions from biogas plants – Methods for measurement, results and effect on greenhouse gas balance of electricity produced”. The presentation describes the state of the art of methane emission measurements at biogas facilities, as well as advantages and disadvantages of several methods to quantify emissions sources and overall plant emissions.

Note: As a result of the auto-play function being accidentally enabled by one of the hosts, from minutes 2:45 – 12:00 at the beginning of the webinar, the slides were advancing every five seconds. The facilitator was able to re-sync the presentation and disable this function, such that the rest of the recording is smooth with no issues.

Erratum: During the webinar, Martin Junginger stated that there are no mandatory sustainability criteria in place for non-industrial use of solid biomass. This is not entirely correct. The UK does have sustainability criteria for the Renewable Heat Incentive and many of these are small scale schemes
 https://www.gov.uk/guidance/sustainability-requirements-for-supplying-and-using-woodfuel. For small schemes these can be met by accrediting the supplier on the Biomass Suppliers list, so that individual users don’t need to do it. A comprehensive overview and comparison of sustainability criteria in a number of EU member countries can also be found here: http://onlinelibrary.wiley.com/doi/10.1002/bbb.1822/abstract

Additional information: One question asked during the Q&A was which share of electricity/energy the use of pellets had in the UK. Some data that breaks down the use of wood (including wood pellets) and its contribution to UK energy is provided here by country: https://www.unece.org/forests/areas-of-work/forestswood-energy/databases.html from where one can find the link for 2013: https://www.unece.org/fileadmin/DAM/timber/wood_energy/jwee2013-web.xlsx Go into the Sources tab and select UK from Cell B4.  This provides the following general data for the UK for 2013:

Role of Wood Energy in Energy Sector 2013
Share of woody biomass in TPES (%) 1.4%
Share of woody biomass in RES (%) 26.4%
Share of wood energy generated from black liquor, energy basis (%) 0.0%
Imported wood fuel as share of wood energy, volume basis (%) 65.2%


Energy Resources 2013
Total primary energy supply, TPES (ktoe) 190,952
Share of renewables (RES) in TPES 5.3%
Total wood energy supply, volume basis (1000 m3) 13,364
Total wood energy supply, energy basis (ktoe) 2,671

The amount of electricity produced by Drax in 2015/2016, and the share of this electricity in the UK mix in these years is given in the following Table:

2015 2016
16% of total UK renewable electricity generated 16% of total UK renewable electricity generated
~8% of UK electricity 7% of UK electricity
26.7 TWh total electricity generated. (11.5 TWh of which was biomass generation) 19.6 TWh total electricity generated (biomass 65% of this)

Algae Bioenergy State of Technology Review

IEA Bioenergy Webinar Series – 25 January 2017

Presented by Lieve L.M. Laurens, Senior Scientist, and Jim McMillan, Chief Engineer both of the National Renewable Energy Laboratory

Even though algae remain an attractive target for bioenergy applications over the longer term because of their high photosynthetic efficiency, the near-term prospects for primary algae-based energy/fuels production are poor due to the relatively high cost of cultivating and harvesting algae. The past 6 years have nonetheless seen substantial progress in research, development and demonstration of algae-based bioenergy and bio-products. With low fossil fuel prices, the algae-based industry is increasingly focusing on manufacturing higher value (non-fuel/energy) products that can be profitable today. Algal biomass-based co-products can provide the critically needed revenue to reduce the net cost of producing algal-based biofuels. As such, a biorefinery approach appears essential to realize the full value of algal biomass. Progress in minimizing/reducing the energy, water, nutrients and land use footprints of integrated algal-based operations needs to be a primary objective of larger scale demonstrations and future research and development.
