United Euro­pean Car Car­ri­ers (UECC) Spear­heads Col­la­bo­ra­ti­on with Indus­try Lea­ders to Advan­ce CNSL as a Sus­tainable Mari­ne Fuel

In a groundbreaking collaboration with industry giants such as maritime advisory organization Lloyd’s Register FOBAS, engine manufacturer Wartsila, and biofuel supplier ACT Group, UECC is leading the charge in critically assessing and evaluating a Cashew Nut Shell Liquid (CNSL)-based biofuel.

As part of this part­ner­ship, ACT Group crea­ted a CNSL-based bio­fuel known as FSI.100, demons­t­ra­ting their com­mit­ment to inno­va­ti­on and sus­taina­bi­li­ty. This was achie­ved through a rigo­rous deve­lo­p­ment pro­cess, which included exten­si­ve engi­ne test­ing and a meti­cu­lous­ly con­trol­led sup­p­ly chain, ear­ning the trust of UECC. Fol­lo­wing tho­rough test­ing on various blend com­bi­na­ti­ons FSI.100 recei­ved appr­oval from engi­ne manu­fac­tu­r­ers as a 30% blend com­po­nent in an ISO 8217 DMA gra­de distil­la­te fuel oil to car­ry out sea tri­als, repre­sen­ting a signi­fi­cant stri­de in the pro­gres­si­on of sus­tainable mari­ne fuels.

FSI.100 addres­ses con­cerns about the popu­la­ri­ty and sui­ta­bi­li­ty of CNSL-based bio­fuels. It also offers com­pel­ling advan­ta­ges: a cer­ti­fied sus­tainable, ful­ly con­trol­led sup­p­ly chain that ensu­res tracea­bi­li­ty and accoun­ta­bi­li­ty from the point of ori­gin to extra­c­tion, con­ver­si­on, and con­sump­ti­on. This approach enhan­ces con­fi­dence in CNSL-derived mari­ne fuels, redu­ces was­te, and pro­mo­tes resour­ce effi­ci­en­cy, alig­ning with cir­cu­lar eco­no­my prin­ci­ples in the mari­ti­me sec­tor. Addi­tio­nal­ly, FSI.100 uti­li­zes sus­tainable land use prac­ti­ces and exhi­bits high-quality mari­ti­me fuel pro­per­ties, such as ultra-low sul­fur and win­ter spec pour points. It also deli­vers signi­fi­cant green­house gas savings, with well-to-wake emis­si­ons reduc­tions of 90% (9.50gCO2eq/MJ) com­pared to con­ven­tio­nal mari­ti­me fuels.

UECC reco­gni­zes the importance of this tho­rough eva­lua­ti­on and trans­pa­ren­cy in sus­tainable fuel pro­cu­re­ment to ensu­re the relia­bi­li­ty and safe­ty of ope­ra­ti­ons, espe­ci­al­ly in light of recent inci­dents in the Rot­ter­dam area that high­light chal­lenges posed by the blen­ding of “unestab­lished” bio­fuel feedstocks in mari­ne fuels. As a pio­neer in sus­tainable Ro-Ro ship­ping, UECC has taken proac­ti­ve steps to address the­se ope­ra­tio­nal issues through its col­la­bo­ra­ti­on with LR FOBAS, Wart­si­la, and ACT Group in deve­lo­ping FSI.100.

Dani­el Gent, Ener­gy & Sus­taina­bi­li­ty Mana­ger at UECC, empha­si­zes the signi­fi­can­ce of this col­la­bo­ra­ti­ve approach, sta­ting, „In our decar­bo­niza­ti­on jour­ney, it’s essen­ti­al to lea­ve no stone untur­ned. UECC is proud to lead the indus­try in not only imple­men­ting crea­ti­ve solu­ti­ons but also estab­li­shing a blue­print for the cri­ti­cal assess­ment of future fuels such as CNSL-based FSI.100, which holds gre­at poten­ti­al for sus­tainable ship­ping.„

The joint efforts bet­ween UECC, LR FOBAS, Wart­si­la, and ACT Group have resul­ted in struc­tu­red and pha­sed pro­ces­ses that include exten­si­ve engi­ne test bench tri­als and ana­ly­ti­cal assess­ments to eva­lua­te the sui­ta­bi­li­ty of CNSL-based FSI.100 blends in both resi­du­al and distil­la­te fuel oils for mari­ne appli­ca­ti­ons. This dili­gent approach ali­gns with UECC’s com­mit­ment to sus­taina­bi­li­ty and respon­si­ble busi­ness practices. 

An important mile­stone for the mari­ti­me indus­try was accom­plished when the col­la­bo­ra­ti­on resul­ted in the pro­vi­sio­nal accep­tance of CNSL- based FSI.100 as a 30% blend com­po­nent in a distil­la­te DMA mari­ne fuel oil, cle­ared by OEM, Class, and flag Admi­nis­tra­ti­ons, for sea-trial stages. This achie­ve­ment unders­cores the importance of trans­pa­ren­cy and rigo­rous eva­lua­ti­on in the adop­ti­on of sus­tainable ship­ping fuels.

Fabio Sca­ra­mel­li is lea­ding the bio­fuels sup­p­ly and tra­ding divi­si­on at ACT Group, and he is encou­ra­ged and invi­go­ra­ted by the col­la­bo­ra­ti­on. He notes, “As inno­va­tors in mari­ti­me sus­taina­bi­li­ty, our part­ner­ship with UECC, LR FOBAS, and Wart­si­la repres­ents a signi­fi­cant step for­ward in advan­cing CNSL-based bio­fuels. The deve­lo­p­ment of FSI.100 high­lights our dedi­ca­ti­on to crea­ting trans­for­ma­ti­ve resour­ces for the sector’s decar­bo­niza­ti­on jour­ney. ”

Gent fur­ther adds, „UECC’s col­la­bo­ra­ti­on with indus­try lea­ders demons­tra­tes our dedi­ca­ti­on to sha­ping the future of sus­tainable ship­ping. By set­ting high stan­dards and embra­cing inno­va­ti­ve solu­ti­ons, we are not only redu­cing emis­si­ons but also dri­ving posi­ti­ve chan­ge across the mari­ti­me indus­try.„

As part of UECC’s com­mit­ment to trans­pa­ren­cy and best prac­ti­ces, the com­pa­ny recom­mends pre­cau­tio­na­ry mea­su­res in bun­ker pro­cu­re­ment, ensu­ring cla­ri­ty on blend com­pon­ents and adhe­rence to estab­lished bio-grade fuel stan­dards. Whe­re the­re are no ‘estab­lished’ fuel stan­dards for the pro­duct being offe­red, then a struc­tu­red pha­sed approach in asses­sing the sui­ta­bi­li­ty of the pro­duct for use on board a ship needs to be taken to gain accep­tance by Class, OEM and Flag for sea tri­als.

UECC calls for indus­try stake­hol­ders to prio­ri­ti­ze col­la­bo­ra­ti­on, trans­pa­ren­cy, and rigo­rous assess­ment in the pur­su­it of sus­tainable ship­ping solu­ti­ons. With con­cer­ted efforts and inno­va­ti­ve approa­ches, the mari­ti­me indus­try can navi­ga­te towards a more sus­tainable future.
