1. Food waste digestion systems.2. Local applications to sustainable anaerobic digestion3. Green Gas4. The role of anaerobic digestion and biogas in the circular

economy5. Validity of BMP results6. Methane emissions7. Sustainable Bioenergy Chains (Collaboration with Task 40)



Methane slippage and sustainability

Must save 70% GHG savings as compared to fossil fuel displaced to be deemed

sustainable

Fossil fuel comparator (FFC) is equal to 186 g CO2eq. per MJ of electricity

30 % of the FFC, which corresponds to 55.8 gCO2/MJ

Slurry storage without digestion assumed to produce 17.5% of methane produced; thus

carbon negative feedstock

All slurry 20% Maize

80% slurry


Renewable Energy Directive requires 3.6% of transport energy by 2030 to be from

advanced biofuels. Ryegrass is a significant source of advanced biofuel.

Decarbonised buses

California Air Resources

Board (CARB) awarded

a Carbon Intensity (CI)

score of -254.94

gCO2e/MJ for a dairy

waste to vehicle fuel

pathway. This is the

lowest ever issued by

CARB.

6 European gas grids have committed to 100% green gas in the gas grid by 2050

Thermal production

of Biomethane

CO + 3H2 = CH4 + H2O

CO2 + 4 H2= CH4 + 2H2O

Seasonal Variation in biomethane yield from Laminaria Digitata


Cultivating Seaweed

Position adjacent to fish farms, protect fish from

jelly fish

Increased yields of seaweed as compared to

pristine waters

Clean water of excess nutrients

Harvest when yield is highest


Higher methane yields after ensiling

can compensate for silage

fermentation losses.

No losses in methane yield occurred

during 90 day storage for 4 of 5

species.

Ambition for Green Gas (of working group Green Gas dec. 2007)

Short term target:Replacement of natural gas by upgraded biogas 1-3%

Midterm target: 8-12% replacement of natural gas in 2020

(4 billion Nm3/y), inclusive SNG production from biomass

Long term: Upscaling to 50% replacement of natural gas by Green Gas in the gasgrid

Differences in gridinjection duringsummer/winter season

21

Several Strategies for Gas Grid Injection;

Different innovative approaches in cooperation with

several grid operators;

Basic challenge is: biomethane production capacity

doesn’t meet gas demand- Direct injection (limited because of gas

demand)

- Development biogas/green gas hubs

- Injection with recompression in gas grid to

higher pressure part of grid

- Development of dedicated biogas grids

with replacement of standard gas boilers

- Pressure regulation in distribution grid in

combination with creation of storage

capacity in distribution grid.(www.sg3.nl)

Mono manure digestion

Development of farm scale Manure digestion

- Electricity production with biogas in CHP

- biomethane production and grid injection for bigger farms

(>=13kton manure)
