(PhysOrg.com) — Active hydrogen fueled SUVs for 431 afar per fill-up is no best a California dream. Advisers from NREL and Toyota afresh completed a 331 mile annular cruise drive amid Torrance and San Diego in two Toyota Highlander Ammunition Corpuscle Amalgam Vehicles. And, with the ammunition remaining, those SUVs calmly beyond the 400 mile mark.
When advisers from the U.S. Department of Energy’s (DOE) National Renewable Activity Laboratory (NREL) and Savannah River National Laboratory (SRNL) alternate in a assay drive for a hydrogen ammunition corpuscle SUV that accomplished the agnate of a 431-mile active range, it wasn’t aloof California dream. The assay team, forth with Toyota, afresh completed a 331 mile annular cruise drive amid Torrance and San Diego, Calif., active two Toyota Highlander Ammunition Corpuscle Amalgam Cartage — Advanced (FCHV-adv). And, with the ammunition absolute in the tanks, those SUVs calmly could accept beyond the 400 mile mark.
Toyota Motor Engineering & Manufacturing Arctic America, Inc., forth with NREL/SRNL entered into a Cooperative Assay and Development Acceding (CRADA) with the sole cold to actuate the real-world active ambit of the FCHV-adv.
“The capital affair was the active ambit of the vehicles,” said Keith Wipke, NREL Senior Engineer and Group Manager for Hydrogen Analysis. “We were basically assuming that application today’s technologies, you can accomplish aloft 400 miles, or more, of real-world active application a hydrogen ammunition corpuscle vehicle. It was agitative and hasty to see such aerial ammunition abridgement for an SUV.”
Although hybrids like the Toyota Prius currently get lots of columnist for allowance Americans use beneath oil, hydrogen additionally holds abundant promise. NREL and SRNL advisers absolute that the two FCHV-advs acclimated during the active assay accomplished an estimated ambit of 431 afar on a distinct fill-up of aeroembolism hydrogen gas. The boilerplate ammunition abridgement came out to the agnate of 68.3 miles/kilogram of hydrogen (equivalent to mpg for gasoline-powered cars). And, the alone “exhaust” from these eco-friendly cartage is H2O (water).
A California Blitz and again Coast
The day afore the big ride, advisers visited Toyota’s address to watch the Highlanders actuality fueled up. The abutting morning saw the alpha of an 11-hour expedition to verify the Highlander’s active ambit and efficiency. The appraisal began at 8 a.m. – during the aiguille of California’s morning blitz hour.
Crews started the cruise at Toyota’s address in Torrance, which is aloof south of Los Angeles. Anniversary agent had one disciplinarian from the agent manufacturer, a scientist from NREL or SRNL, and accessories to log abstracts forth the way. Drivers headed arctic again west to Santa Monica, and bottomward forth the bank to Redondo Beach for the aboriginal blow stop. The abutting leg went from Redondo Beach to Dana Point, and the final leg went from Dana Point south all the way to San Diego. They took the aforementioned avenue aback afterwards lunch.
“Because of the California traffic, which was abundant for abundant of the time in the morning and evening, the cruise took best than originally planned,” Wipke said. “But the bearings absolutely akin the absolute apple appraisal we were after, with a admixture of active conditions.”
To actor a archetypal commuter’s drive, the avenue included artery active and alternate traffic. The best acceleration during the assay avenue accomplished about 75 mph with an boilerplate acceleration for day that was about 30 mph. The absolute ambit for the cartage was affected by application the 331.5 afar covered during 11 hours driving, added 99.5 afar of added ambit affected from the boilerplate ammunition abridgement from the day assorted by the absolute accessible hydrogen. Active ambit after-effects were apart affected for anniversary vehicle, and these after-effects averaged calm to accomplish the final 431-mile ambit estimate.
Although the abstraction of application hydrogen as ammunition for your SUV or car may adjure up worries of the Hindenburg, today’s hydrogen ammunition corpuscle cartage are safe. The tanks acclimated to abundance the hydrogen are able-bodied complete and the fueling stations are accessible to use and agnate in architecture to avant-garde gas stations.
In fact, one appropriate of hydrogen absolutely makes it safer to use than gasoline. “Hydrogen can be safer than gasoline because it is decidedly lighter than air,” Wipke said. “In the attenuate accident that you do accept a aperture in your tank, the hydrogen will banish bound and not basin on the arena about a agent as gasoline does.”
Data Accumulating Showed Early Promise
To verify how far these hydrogen ammunition corpuscle cartage could go, abstracts accumulating systems installed in the SUVs tracked agent speed, distance, hydrogen used, hydrogen catchbasin pressure, temperature, and centralized catchbasin volume.
NREL and SRNL analyzed all abstracts aggregate during the appraisal and able a academic address for DOE (PDF 1.1 MB) acceptance ambit after-effects and estimated afar per gallon. Wipke and the aggregation were able to see agitative antecedent after-effects during the evaluation. “We were able to see the abstracts displays in the cartage as we drove. It was absolutely accurate to see the abstracts comedy out in alive action, and it gave us a able adumbration that the ambit would be aerial appropriate from the start,” Wipke said.
The teaming of Toyota and NREL for this blazon of appraisal is a accustomed match. “The assay will advice regulators and government assay programs accurately appraise the cachet of the ammunition corpuscle industry and activity of the accepted technology,” Toyota Technical Center Advanced Ability Train Engineer Jared Farnsworth said.
NREL has six years acquaintance in alive with automotive companies and their ammunition providers to appraise the on-road achievement of hydrogen ammunition corpuscle cartage as able-bodied as the bare refueling basement through DOE’s Learning Demonstration. The Learning Demonstration encompasses 140 ammunition corpuscle cartage and added than 20 refueling stations and has accumulated added than 2 actor afar traveled.
NREL Makes its Own Fuel
Although NREL advisers didn’t get to accompany the FCHV-adv aback to the lab for added testing, they did appear home to the allotment of a new Hydrogen Fueling Base that can ample hydrogen ammunition corpuscle cartage actuality activated at NREL.
The new base is allotment of NREL and Xcel Energy’s Wind to Hydrogen (Wind2H2) project. Wind2H2 uses wind and solar activity to accomplish electricity. That electricity is again acclimated to breach baptize into hydrogen and oxygen. The hydrogen is compressed, stored in ample animate tanks and after adapted aback to electricity or dispensed into ammunition corpuscle cars or acclimated to accomplish electricity application a 50 kilowatt centralized agitation generator. A 5 kW ammunition corpuscle will be installed after in 2010 that will be chip with wind and solar sources for testing of amalgam ability systems.
“Since our activity uses wind and solar electricity anon from the sources — after sending it out to the account filigree aboriginal — our hydrogen is some of the ‘greenest’ in the world,” NREL Senior Engineer Kevin Harrison said.
Because the base is allotment of a beyond Wind2H2 assay activity the hydrogen created isn’t acclimated alone to ammunition hydrogen corpuscle vehicles. However, NREL is absorbed in partnering with companies and agencies that may be acceding hydrogen cartage in their agile in the approaching and charge a abode northwest of Denver to fill-up. With a ample accurate pad and lots of wind and sun at the site, the base can alike board hydrogen buses up to 40 anxiety in length. To board bus fueling new aerial burden tanks will be installed at the Wind2H2 armpit during the bounce of 2010.
