Fueling Stations of the Future Here Now
The 21st century’s just about sure to see the end of what, in terms of human evolution, has been aptly dubbed “The Fossil Fuel Era.” The transition to cleaner, renewable forms of energy and power — be it for lighting, heating, cooling or industry — is (pardon the pun) gaining steam. And while gains are slower and more difficult to come by, the same can be said when it comes to transportation, that other major component of fossil fuel consumption and greenhouse gas emissions.
A growing number of entrepreneurial companies — from multinational giants such as GE to small-scale newcomers, such as Tesla, A123, and a bevy of others — are hard at work developing electric, flex and hybrid fuel vehicles, as well as the infrastructure to support them.
There’s good reason to believe that this surge in the search and development of clean, alternative fuel vehicles and infrastructure will be different; that a drop in oil, gasoline and diesel prices won’t be enough to derail progess, as happened in the eighties and nineties subsequent to the oil crises of the 1970s. Two news items this past week provide supporting evidence.
Of Skypumps and Solar Trees
GE’s industrial division and Urban Green Energy (UGE) came out with word that the first installation of their Sanya Skypump is up and running at the headquarters of environmental services company Cespa near Barcelona, Spain. Integrating New York–based Urban Green Energy’s 4-kW vertical-axis wind turbines (VAWTs) and GE’s DuraStation EV chargers, the Sanya Skypump points the way toward fueling stations of the future that gather all the energy they need from the wind.
Along a similar vein, San Diego’s Envision Solar announced it has successfully completed engineering and manufacturing of its first run of pre-cast concrete columns for its Solar Tree arrays. Parking lots are ideal sites for Envision’s Solar Trees. Combine them with EV chargers and you have a clean, renewable fueling station right where EV motorists need and want it.
The Sanya Skypump can fully charge EVs in 4-8 hours, using electricity produced by UGE’s 4-kW VAWT, which stands 42 feet high, according to the partner companies. Winds of at least 7 mph are needed to generate electricity.
Plans are in the works to install Sanya Skypump EV fueling stations in the US and Australia before year-end, GE and UGE say. Sites include shopping malls and universities, as well as other locations.
A big advantage of the Sanya Skypump wind-powered EV fueling station is its installation time. The entire system takes less than two hours to get up and running, the companies say.
Envision Solar’s new pre-cast Solar Tree concrete columns are part of its “Drag & Drop Infrastructure” product line, one that “offers much faster, more efficient deployment of Solar Tree structures,” the company explains.
“We are continually leveraging technology to increase our efficiency and quality. We call this new modularized approach: Drag & Drop Infrastructure™ — creating the shortest possible time and ease for deploying the best solar shaded parking products in the industry with the least disruption in the field,” Envision Solar president and CEO Desmond Wheatley elaborated.
“That means lower costs, lower risks, higher quality and higher customer satisfaction. We have to take these steps in order to efficiently meet the volume demands that our business development activities will be creating. We are in this to deploy thousands of Solar Tree arrays and we are going to have to be highly efficient to get that done.”
Manufacturing the concrete columns in a controlled environment enables Envision to produce the highest quality results. It also makes for much more efficient installations. The new Solar Tree columns enable Envision to install the solar PV structures in hours rather than the days or even weeks required for columns that are cast in place, director of Program Management Peter Seiler added.
