3.  Denmark ◦ Higher RES waste – negative electricity pricing ◦ Implemented procurement strategies earlier ◦ National and regional support both  Sweden ◦ Vätgas Sverige  H 2 Skåne ◦ Procurement strategies recent ◦ Primarily regional support Aguilera & Mathew, 2012

4. AdvantagesChallenges Potential to utilize industry by- products eg. Chlor alkali Infrastructure investments, Production and Maintenance costs Final products are water and electricity Ongoing and future R&D needed Applicability in different sectors: Transport CHP Uninterrupted Power Supply (UPS) Inclusion of Hydrogen in Swedish national energy goals and RE subsidies Vs. Battery: Transport – better electromobility UPS – large scale H 2 cheaper More widespread on small scale (eg.fuel cell electric vehicles) Synergistic relationship with biofuels Volatility of H 2 in properties and reactions
