gHowever，hydrogen has significant limitations whcn it comes to delivery andrefueling.These roadblocks，combined with hydrogen's convincing potential of rcducingCOemissions，motivateda team of researchers led by William H.Grecn.Theyintendedto explore a way totransport and store hydrogen usingliguid organic hydrogencarriers（LOHCs），which are organic substancesthat can absorb and release hydrogengthrough chemical reactions. The team is developing a new technology that allowsVLOHCs to not onlydeliver hydrogen to the trucksbut alsostore hydrogen onboard.Currently，LOHCs，which work within the existing system of fuel distribution，areused to deliver hydrogen to refueling stations,where itis then processed and deliveredonto trucksequippedwith hydrogen fuel cells.“The current approach causes significant energy loss at the refueling station,”saysGreen.“To address this，our work is exploring a more efficient application，withLOHCs-powered trucksfeaturingonboarddehydrogenation（脱氢）.”To carry outsuch a design，theteam aims toadjust the truck'spowertrain（传动系统）to allow onboard hydrogen release from theLOHCs，usingwaste heat fromtheengineexhaustpipe（排气管）.Thedehydrogenationprocesshappenswithina high-temperature reactor,which continually receives hydrogen-rich LOHCsfrom the fuelstorage tank.Hydrogen released from the reactor isfed to the engine.On itsway to theengine,some of thehydrogen is redirected to a burner to heat the reactor,which helpsincrease the reactor heating.Regardless of technical improvements,these existing options remain quite expensivedue to the high cost of hydrogen delivery.“Using hydrogen is an option that is globallyaccessible，and couldbe extended to countries like the one where I'mfrom，”saysMoreno Sader，who is from Colombia.“Since it works well with existing supportingfacilities,large investments in advance are unnecessary.The global applicability is huge.There is also an enormouspotential toimprovedelivery andrefueling to further reducethe cost,and our system isworking to do that,”says Sader.28.Whathaskept hydrogen frombeingwidelyused？A.Its potential threat to the environment.B.Its complexprocess of power generation.C.Its restrictions on shipment and refuelingD.Its inconvenience in production29.What can weknow about the team's newtechnology？A.It enhances truckscarrying capacity.B.It is intended tocarry dangerous gases.C.It helps design a new type of transport truck.D.Itmakes innovations based onpresentLOHCs.30.What doesparagraph 5mainly focuson？A.Added information aboutLOHCs.B.Challenges of redesigning the truck's powertrain.C.An explanation of the onboard dehydrogenation process.D.Advantages of usinghydrogen in long-distance transportation.英语试题（雅礼版）第5页（共10页）
