Hummer, the epitome of all that’s wasteful in our society, is winding down

Wednesday, February 24th, 2010

Turns out the Chinese couldn’t get it together, as attempts by Sichuan Tengzhong Heavy Industrial Machines Co. Ltd. to acquire GM’s Hummer division have fallen through. GM, in response, announced today it will begin the orderly wind-down of Hummer. Sure, some Saudi prince could decide to step in and buy the operation at the last minute as his own play thing, but I doubt it. GM didn’t say why the deal couldn’t be complete, but who cares: one of the world’s most wasteful and pointless machines is at the end of its road. Sorry Arnie.

Waste Management invests in Enerkem as part of $53.8 million round

Wednesday, February 24th, 2010

Kudos to Vincent Chornet. The president, CEO and co-founder of Montreal-based Enerkem (along with his father, Esteban) has in just a few years turned his company into a leading player in the emerging waste-to-fuel market. Today, Enerkem gained even more momentum, announcing it had secured $53.8 million in venture financing in a round that included Houston-based Waste Management, the continent’s top waste-management firm.

Enerkem uses a thermochemical fluidized-bed process to gasify municipal solid waste (organics, wood waste, plastics), demolition wood, and agricultural/forest residues. The resulting syngas is cleaned and, using a proven catalyst, can be turned into a variety of end products, including methanol, ethanol and high-value olefins (plastics). The company is in the process of building a waste-to-ethanol facility in Mississippi (75 million litres a year) and an Edmonton plant (36 million litres a year) that will also turn sorted municipal solid waste into ethanol. The Edmonton facility is being done in partnership with Greenfield Ethanol, Canada’s largest independent ethanol producer. Meanwhile, in Westbury, Quebec, the company has a commercial-scale demonstration facility that currently turns old wooden hydro poles into ethanol.

Rho Ventures, Braemar Energy Ventures and BDR Capital, all existing investors, participated in the financing round with Waste Management, along with new investor Cycle Capital. “This financing round validates Enerkem’s business and advances our path towards leadership in the waste and advanced fuels markets,” said Chornet in a release. In an earlier story (July 2008) I wrote for Greentech Media, Chornet said that burning waste or burning the syngas created from waste is, well, a waste. Based on electricity and ethanol prices at the time, a company can make three times more revenue per tonne of processed waste compared to a plant that simply burns its syngas to generate electricity, he said. Chornet also said Enerkem’s process is profitable with oil at $50 a barrel and if the company can get a competitive tipping fee to take the garage.

Large-scale storage of wind energy using compressed nitrogen and old pipelines… Could it work?

Monday, February 22nd, 2010


I just got back from a trip last week to Edmonton, Alberta, where I visited a startup called Lancaster Wind. I’ve been following this company for over a year now, but only recently has its founder and CEO — Dave McConnell — started talking about his approach to storing huge amounts of energy in the same pipelines used to carry oil and natural gas. You can read about it in my Clean Break column today, as well as in two stories recently written in the Edmonton Journal, here and here.

The basic idea is that specially designed hydraulic wind turbines are used to compress nitrogen into existing gas or oil pipeline infrastructure, some of it unused throughout North America. Several hundred, even thousand, kilometres of pipeline could be filled with nitrogen and kept under pressure, in effect becoming a kind of massive nitrogen battery for wind. When electricity needs to be generated anywhere along the pipeline, the nitrogen gas is released and expands to turn a turbine that generates electricity. Wind, under this setup, suddenly becomes dispatchable and has baseload characteristics. Also, the pipeline eliminates the need for transmission lines.

There’s still much to learn about Lancaster’s approach, but it’s an intriguing idea that in my mind is worth investigating. Some questions: Can these pipelines handle the expansion/compression cycles over time? How efficient would the process be? Can such a small company pull off such an ambitious feat? How does it compete with other options, such as compressed-air cavern storage or pumped storage or even flow batteries?

Stay tuned…

Spin is in, but climate change still here

Monday, February 15th, 2010

My Clean Break column today is a shot back at those skeptics in the media who are hopping on the kill-the-IPCC bandwagon. I’ve pasted below the fuller version of the column, which was cut to get into the paper:

Spin is in, but climate change still there
Hardcore climate skeptics smell blood and so do some in the mainstream media, adding momentum to a boisterous campaign to discredit and confuse

Tyler Hamilton
Energy Reporter

The following e-mail arrived last week from an instructor at Seneca College. He was gleeful, commenting on all the negative publicity recently directed at the Intergovernmental Panel on Climate Change.

“How will the Star explain to her devoted believer’s (sic) why Al Gore and David Suzuki are being led away in handcuffs?” he wrote. “ClimateGate, ThermometerGate, GlacierGate, AmazonGate… Button up Mr. Clean – it’s real (sic) cold out there this winter.”

These taunting, often hateful e-mails arrive all the time from folks who don’t believe climate change (human caused or otherwise) is happening, and who believe their case is strengthened every time some libertarian pundit adds to their arsenal of doubt.

They mock the green economy and green energy. On climate action, they worship the status quo. Lately, they smell blood. And like underfed sharks at an annual seal gathering, they’re whipping themselves into a frenzy in hopes of turning a scratch into a fatal gorging.

Sarah Palin is now writing off all climate science as “a bunch of snake oil.” Fox News host Glenn Beck said last week that IPCC scientists have so dishonoured themselves they should perform hara-kiri – that is, commit mass suicide by plunging a sword into their bellies.

Here in Canada, the Financial Post’s resident libertarian Terence Corcoran wrote a column in late January with a headline that shouted “Climate agency going up in flames,” while the Globe and Mail’s Margaret Wente wrote early in February that “the science scandals just keep on coming” and that the entire climate-change movement has been discredited. Columnist Rex Murphy, who has fittingly moved on to the National Post is pretty much saying the same thing, only with bigger words.

Wishful thinking doesn’t make it so.

Interestingly, both Corcoran and Wente supported their arguments by mentioning how climate scientist Andrew Weaver from the University of Victoria is, in the words of Wente, among the many climate scientists who “sense a sinking ship” and are “bailing out.” Corcoran wrote that Weaver is “heading for the exits” and this is “firm evidence that the IPCC is in trouble.”

Here’s what Weaver had to say last Wednesday when asked by the Star about the recent coverage. “It would be nice if they actually called me,” he said, referring to Wente, Corcoran and some journalists in England. (more…)

Ontario news: Grid storage project, acquisitions and Vestas

Thursday, February 11th, 2010

Mississauga-based Electrovaya Inc., maker of lithium-ion Superpolymer batteries, is supplying batteries for a utility-scale energy storage project being spearheaded by CEATI International Inc. of Montreal, an advanced technology centre for utilities. The $7.5 million project will be a large-scale initiative involving multiple utilities and sites. The batteries will be tested as storage for renewable energy generation and as a way to ease distribution and transmission bottlenecks in high-density urban areas. CEATI will also investigate the repurposing of electric-vehicle batteries for smart-grid applications, given that a battery that outlives its usefulness in a vehicle can still be used for many years as general energy storage for the grid.

On the acquisition front, two more promising Ontario cleantech ventures have been plucked up by U.S. firms. On Tuesday Toronto-based biogas maker Stormfisher Biogas announced it had been acquired by Virginia-based Greenhouse Gas Services. Despite having one of the most boring and uninspiring names, Greenhouse Gas Services is a venture of GE Energy Financial Services and AES Corp., so it has some serious backing. The company invests in and develops projects that reduce greenhouse-gas emissions, and it then sells the carbon credits. So here’s my question: If some of the biggest Stormfisher projects are expected to be in Ontario, and since the Ontario Power Authority doesn’t appear to be letting biogas projects keep carbon credits, then what’s in it for Greenhouse Gas Services? I can only speculate that the power authority has quietly decided to let developers keep credits from methane destruction. Something I’ll have to follow up on.

And just today, Sunnyvale, Calif.-based Calisolar announced it had acquired Vaughan, Ontario-based 6N Silicon, a maker of solar-grade silicon that will operate as a wholly owned subsidiary. “In addition, $22.5 million in funding was raised from existing Calisolar and 6N investors,” the companies said in a statement. “The new funds will be used to increase capacity at the Sunnyvale, California cell manufacturing facility and expand silicon purification operations in Vaughan, Ontario.” It’s sad to see 6N fall under foreign ownership so early in its life, but the good news is that Calisolar is likely to set up some module assembly in Ontario to take advantage of the feed-in-tariff program here. Given that its solar cells will contain 6N’s silicon, the company will be well positioned to meet Ontario’s local content requirements and even supply other cell/module makers.

Finally, I have a follow to my story about Vestas and the possibility it will lay roots in Ontario. I spoke Wednesday to the company’s head of global offshore markets, who spoke highly of the Trillium projects and called the opportunity to develop offshore wind in the Great Lakes “fantastic.” He wouldn’t say if Vestas plans to establish manufacturing in Ontario — which isn’t surprising — but given the potential in the Great Lakes, the liklihood of Trillium’s projects moving forward first, and the positive policy and regulatory environment in Ontario (including the feed-in-tariff program, which offers 19 cents per kilowatt-hour for offshore wind power), all the stars are aligned and it’s only a matter of time before Vestas makes its move.
