58 In Summary Part 1 Black liquor (BL) gasification works. Presence of alkali in the BL fuel results in complete carbon conversion at around 1000 deg C gasification temperature Laboratory work indicates that pyrolysis oil can be mixed with BL in significant amounts and that the catalytic effect still results in full carbon conversion at around 1000 deg C At a mix of 25% PO in 75% BL (dry basis) the syngas generation increases with about 100% Lab scale tests indicates that alkali supported gasification can be extended to other feedstocks such as manure, WWT sludge and meet and bone meal. 58

59 In summary Part 2 New SECA regulation demands new, low sulphur bunker fuels Methanol can become a cost effective bunker fuel alternative, cheaper and simpler to use than LNG Bunker Methanol infrastructure in harbors can stimulate DME production at optimum locations from a distribution point of view BioMethanol can be transported to the bunker Methanol infrastructure / DME production facilities and make the DME (and methanol) partly renewable It is cost effective and comparably simple to introduce a new fuel in the HD transport sector which uses about 25% of all transportation fuels (relates to Sweden but is similar in rest of Europe) 59
