WP2 main goals:• Establish an accurate picture of which appliances/utilisations we have today• Evaluate as far as possible the evolution of the stock• Evaluate the sensitivity of existing and new technology to gas quality change( green gases, LNG, etc..)
WP2 input Models & scenarios WP 3,4 etc.
Which gas applications and utilisations are compatiblewith the future gases?

Impact of gas quality on air factor (boilers without CC)Nominal condition = 100% methane
Air & gas volumes areconstant
Not enough air when the Wobbeincreases (eg. LNG)
Too much air whenWobbe decreases(eg. Biomethane)
Increase of CO = safety issues

Conclusion
- WP2 is bringing input to other WPs:- Quantitative info: How many appliances, gas consumption, tolerance to gas
quality etc.- Qualitative info: Which technologies are on the way (e.g. hybrid boilers),
what are the technical solutions to increase tolerance to gas quality variations, etc.
- Synergy between the FG project & Marcogaz, IGU, EU harmonisation process, etc..
- A large share of the work programme is executed
