GVR, which has about 24,000 members, is frequently cited as the reason why new retirees choose Green Valley. Several times a year, the public is invited to craft shows at the West Center, and art exhibits can be viewed in the lobbies of several of the recreation center. It also offers a mix of leisure classes, concerts, movies and other entertainment, as well as facilities for lapidary, ceramics, pottery, woodworking, photography, billiards, computer instruction and more. Included are Pickleball, tennis, swimming, bocce, racquetball and state-of-the art fitness centers. Many residents are members of Green Valley Recreation Inc., a non-profit services corporation that operates 13 recreation centers. Duffers will find a great selection of golf courses in the area, all of which offer opportunities to play yearround. Green Valley, at an elevation of 2,900 feet, is often described as a golfer’s paradise. Just up the road in Sahuarita are a mix of shopping centers, including the Madera Marketplace, Sahuarita Plaza, Valley Verde Center, Rancho Sahuarita Marketplace, as well as The Crossing at Sahuarita on Abrego Drive and Nogales Highway and The Corner at Rancho Sahuarita. In the future, the station may also use the ATR process to produce hydrogen from ethanol.Ĭhevron is also working on single-step reforming (SSR): a process presented at the National Hydrogen Association conference in 2005 that converts natural gas and steam into near-pure hydrogen in a single step, with potentially significant cost savings.ĪC Transit is one of the largest transit agencies in California, serving more than 64 million passengers a year throughout a 360-square mile region.PHOTO BY CAROLYN MAZAIKA OPPOSITE PAGE, BOTTOM:Ĭanoa Hills bocce ball. This mixture must be processed further to produce the essentially pure hydrogen required for use in fuel cell vehicles. The hydrogen gas produced from ATR is a mixture of hydrogen, nitrogen (from the air), carbon dioxide and small quantities of other gases. What they do is maintain these petabytes of data everything from CO 2 levels, temperatures, radiation from satellites. He worked in the Langley Research Center’s atmospheric science data center, which stores the satellite-generated data that’s constantly raining down to Earth. This station produces 12 kg of hydrogen per day.Īutothermal reforming uses a process in which natural gas is reacted catalytically at high temperature with oxygen and steam at high temperature to produce hydrogen. Mazaika wasn’t actually a rocket scientist at NASA. Dri mazaika how to#(A Chevron Technology Ventures engineer described the difference between the two operations as knowing how to build an elephant, and figuring out how to build an ant.)Īnother Chevron hydrogen energy station built at the Hyundai-Kia America technical Center in Chino uses autothermal reforming (ATR) rather than steam methane reforming to produce hydrogen from natural gas. The mainstream refinery operation that focuses on the bulk production of hydrogen for use in refining processes isn’t involved. The hydrogen production and refueling component is driven by Chevron Technology Ventures-a subsidiary of Chevron that is focused on new energy technologies, including wind and biofuels. The HyRoad project is part of the DOE Technology Validation program. The 6,250 psi pressure at the pump dispenser is appropriate to fuel vehicle tanks to 5,000 psi. Dri mazaika series#This is further compressed to 6,250 psi, and stored in a series of cascade storage vessels. A pressure swing absorption (PSA) unit accepts the compressed reformate and delivers 99.99% pure hydrogen. Here at Your First Step, we can help you to find 1-85 the right drug abuse treatment program in Fawn Creek, KS that addresses your needs. The reformate is compressed to approximately 125 psi-the pressure needed to separate hydrogen from contaminants in the gas stream. The two Steam Methane Reformers produce a reformate stream typically composed of 75% hydrogen, 20% CO 2 and other trace gases including CO and CH 4 (methane). The Chevron hydrogen station will dispense up to 150 kg of hydrogen daily-enough to fuel the three 40-foot fuel cell buses and 10 fuel cell vehicles.

The Chevron hydrogen energy station uses dual on-site steam methane reformers (SMR) to produce hydrogen from natural gas.
