Ze-gen Ramps Up its Waste Gasification Process: Lessons from a Clean-Energy Startup

reduce recycling. But that’s an “illogical” fear, Davis says, since C&D waste like that used in Ze-gen’s demonstration plant has already been recycled—the company gasifies what’s left after everything recyclable has already been recovered.

Fortunately for Ze-gen, the Waxman-Markey climate and energy bill passed by the U.S. House of Representatives this summer includes a provision ensuring that C&D waste gasification would count as a form of renewable energy. Davis says two large non-governmental organizations lobbied specifically on Ze-gen’s behalf for the inclusion of that language. “I’m not allowed to mention the name of the groups that lobbied for us, but they recognize the perversion of disincentivizing advanced technology while awarding incineration and landfilling,” Davis says.

The Senate, however, has yet to come up with its own version of climate and energy legislation—so Ze-gen could still use some friends in high places.

Be open to redefining your market as the economy dictates.

The main problem for U.S.-based energy entrepreneurs has always been that fossil fuels are so cheap here, meaning there’s little incentive to invest in alternatives. In 2008, when petroleum and natural gas prices shot up, it looked like the economics of cleantech might finally be changing, but the spike was short-lived. That could force Ze-gen to look outside the U.S. for its eventual commercialization partners, not to mention its customers.

“A year ago, natural gas cost around $12 per mmBTUs [million British thermal units], and today it’s $3 per mmBTU,” Davis observes. “It’s very difficult to imagine going ahead and building a plant with coventional financing, unless there are either [regulatory] incentives or higher fuel prices. That’s not an argument for giving up, but rather for looking to places that have different economics than in the U.S. We have very cheap natural gas relative to the rest of the world, other than the Middle East. It’s going to stay cheap for a while. But if you go to the U.K. or other countries dependent on natural gas, things are very different.”

So, look for Ze-gen to start exploring foreign markets soon after building its next plant. And watch this space for further developments—Davis says news about the company’s joint venture agreement is coming soon.

Between 2007 and 2014, I was a staff editor for Xconomy in Boston and San Francisco. Since 2008 I've been writing a weekly opinion/review column called VOX: The Voice of Xperience. (From 2008 to 2013 the column was known as World Wide Wade.) I've been writing about science and technology professionally since 1994. Before joining Xconomy in 2007, I was a staff member at MIT’s Technology Review from 2001 to 2006, serving as senior editor, San Francisco bureau chief, and executive editor of TechnologyReview.com. Before that, I was the Boston bureau reporter for Science, managing editor of supercomputing publications at NASA Ames Research Center, and Web editor at e-book pioneer NuvoMedia. I have a B.A. in the history of science from Harvard College and a PhD in the history and social study of science and technology from MIT. I've published articles in Science, Technology Review, IEEE Spectrum, Encyclopaedia Brittanica, Technology and Culture, Alaska Airlines Magazine, and World Business, and I've been a guest of NPR, CNN, CNBC, NECN, WGBH and the PBS NewsHour. I'm a frequent conference participant and enjoy opportunities to moderate panel discussions and on-stage chats.
