Members:
Biogas plant owners, constructors, consultants, supsuppliers, energy sector, waste sector, agriculture, research etcetera .
Mission:
Promote framework conditions for production and use of biogas contributing to meet societal challenges:
climate change
eutrophication

5. Why methanation of H2 at the biogas plants ?
DDK 50 billion invested in high capacity gasstorage and gasdistribution in Denmark.
Maximum up to 8 % H2 Can be handled throug the gas grid
Methan is already the basic gas in the grid.
Concentrated CO2 available at the biogas plants.
Gas grid connection in place at most of the biogas plants.
Methanation with high effincicy in several ways
- biological can save upgrading cost
- chemical in combination with electrolysis
80 % efficency demonstrated .

6. Gassystem: high storage capacity
Gas grid
Gas system storage (11 TWh el. P2G)
International grids (electricity)
District heating with seasonal storage
District heating with normal storage
Individual heat pumps
Electric and plug-in hybrid cars (3035)
0.1 TWh electricity

7. Biogas –as the backbone in a future green energy system ?
Biogas –as the backbone in a future green energy system ?
Biogas:
Unique energy source combined with the gas system plus gas storage
Effective tecnologies ready for the entire value chain. Gasengines, boilers, buses, cars, fuelcells etc.
High system capacity and flexibility
Biogas a limited resource
Therefore
An important backup role
(cover the gaps from wind and solar )

8. Coverage of Denmark´s gasconsumption - now and in the future
Coverage of Denmark´s gasconsumption - now and in the future
Future: 2050: 100 % gas consumption: Fossil free
50 – 75 PJ Biogas potential +
? PJ P2G (Power to Gas)
Now: : 20 % of gas consumption: Biogas
13 PJ injected in gas grid
7 PJ direct supply to CHP or process industry
Next goal: 2030: 50 % of gas consumption: Biogas

10. New energy agreement June 29 2018
Existing biogas plants guaranteed current tarifs
Until 2032 or at least 20 years for each plant
Projects in progress may be established until ”2020”
Existing plants can expand without limits until ”2020”
within ”certain limits” after ”2020”
A new system will be phased in after 2020

14. Danish process industry is dependence of gas
Danish process industry is dependence of gas
The process industry accounts for approx. 35 pct. of the Danish gas consumption or approx.
700 million m3 / year. (28 PJ)
The gas's purity and regulating ability are important in many industrial processes
Extra cost 0.7 billion. Kr/y if switching from natural gas to wood pellets or electricity.(EA energianalyse 2017)
Danish Biogas Association

15. Biogas for individual heat supply
Biogas for individual heat supply
The heat pump covers 80 pct. with VE -electricity.
Biometane covers 20 pct.
(when cold or high electricity prices)
Below 30 per cent grid load in relation to electric heat pump
App. 500 MWel potential for flexibility
With fixed heat price from agregator
Covers the gas villa market with just 0,12 bill. m3 biomethane pr yr. (6 PJ)

Potential for biogas in heavy transport sector
Gradual substitution of ⅓ of the fuel with 10 PJ of biogas (250 million m3 of methane / year) reduces greenhouse gas emissions by 2.4 million. tons of CO2 equivalents until 2030

18.
In cooperation, the gas- and biogas industry has a unique concept for the green transition
The natural gas system has high capacity, storage facility and deliver security of supply.
Ideal back up for fluctuating wind and sun.
Biogas makes the gas CO2 neutral and fossil free
Biogas provide circular economy in practice for agriculture and waste sector
We should work together to communicate this
as it have a high value for Denmark .
The Government’s announced forthcoming gas strategy will be crucial for the gas future.
