In the North we are doing quite well in achieving our targets!!
• EU targets 20 – 20 - 20• Targets are expected to
be achieved by 2020
1.december 2016
• Targets for 2030 • Greenhouse gas-reductions of 40% compared to 1990
• Within ETS 43% compared to 2005• Outside ETS 30% compared to 2005 – Denmark expectedly
to reduce 39%.
• Renewables to cover 27% of EU's gross energyconsumption

Where can we use gas in the transition phase?
•Gas in Transport• Heavy transport – person transport also a possibility
•Need for balancing wind and solar • Power balancing by gas – fast in ramping and quite
inexpensive• Interconnectors can do quite a lot
• In periods with low wind we will need a back-up• Central and/or decentralised power plants running on gas?• Short periods = Use of Gas turbines
•Long term storage facility• Short term might not be needed – flexibility, electric cars…

Need for regulation on a national scale
•Too little connection between gas and other fuelsor carriers• Regulation for power and heat has strong influence on gas
•The gas regulation should be more suited to supplying varying amounts of gas• Capacity is the key word….• Is it too expensive today to utilise the gas infrastructure to
boost capacity?• Interesting with combined heat pumps and gas boilers,
however not economic feasible because of the tax system
•Support to Biogas should incentivise to competition with other renewable technologies• Biogas needs to be cheaper
