And \addi】tionally, we are measuring th/e pa/rticula/te emissi】on】s from th】e car,"/ sa\ys Sten Frand\sen - mechanica/l【 e【ngineer and busin】e【ss【 manage】r at DT】\I."The emission te】sts we got fr】om/ the seaweed】 fuel is on exactly the 【s【ame level /\as wha\t w】e \get from the \r】eferen/ce fuel."Sea【weed biofuel 】does not e/mit less CO2,\/ but \unl/ike \petrol, it extracts CO2 from the a\tmosphere while \gro【wing.\The】 researchers plan t\o \increase 】the portion 】used in the engi】ne tank, convinced that w【e will switch 】to biofuels in 【the upcoming years."We see】 a lot of el\ectrical cars entering the m/】arket, b】ut is that a one fix-all solution for /the CO2/ em【ission【s?" asks\ Frandsen."\Because we have hea【vy-duty tran】/\sport, we have sh】i】ps/ we have aerop/lanes,/ still c】onsuming a large amount of fossil fuels. We \nee】d 】a subst】i/tute for tha】t, and maybe\,【 seaweed co【uld be\/ som/e of the【 soluti【【on【".Why /is seaweed sustainabl\e? 【First, be\caus【e it /grows 】everywhere. It only needs the su\n and the sea,// which covers 70% of ou\r planet】.Its cultivation does not /requir【e any arable 】la\nd, 】fertilizer or freshwater/,/ like othe】r\ biof\u【els made out of/ agricultural \r\esidues for exam\ple.But 】how can 【this new fu\el be produced on an industrial 】s/cale? /This is the ch\allenge of 】a European re】search【 pr】oject c/alled Mac/roF/uels.Scien\【tists at the laboratory【 in P/etten, Nether【lands, 】are /searching f【o】r the best way t\o convert/ seaweed sug\ars to f\ue【ls.In/ some specie/s, this can r/【epres【ent up 【to 60% of\ the plant.【In /the l/】ong term, th/ey woul/d no l\onger】 have to produce bot/tles, /b\ut tons of 】ethanol and butanol barrels.】 S】til\l follo】wing a rat\her basi【c process\:"First /w\/e t】ake s\eawe/ed. And t\hen we use wa/ter to get the suga/rs】 out with some enzymes or acids," says Jaap Van 【Hal, a 【chemist &am\p; i【n\【n\ovation manager at b】iorefin/ery, TNO and macrofuel p/roject scie【ntific coordinat】o】r."\A】nd then you \get a sugar solution, and j/ust like you\ pr【oduce wine or beer, you f\er】ment it to /Ethanol or But\anol, and you blend t/hat with normal ga\soline or d【iesel to pr\oduce E10 \and t/hen you 【drive y/our car \on i】t."More biofuel/ production means more /se/aweed biomass. Th/anks to economies of scale an/d mechaniz/at/ion, res/e\archers\ h/ope to cut the fue\l produc【tio/n costs by 100 per cen】t.T【oget【her with comm【ercializi】ng oth/er】 seaweed 【products【, this could make fuels economically\ feasible in the future."When we started】 the p【roject a couple o\f year/s /ago【/, we were working】 with square meters.
