Cement maker first in world to capture CO2 with algae

Thursday, March 18th, 2010

We all know that making cement is an energy-intensive process, so when carbon prices are introduced in North America it’s going to have a major impact on an industry that quite literally lays at the foundation of our economy. In Ontario, cement maker St. Marys Cement — now part of Brazilian conglomerate Groupo Votorantim – has partnered with stealthy startup Pond Biofuels of Toronto on a project that, since last fall, has already started to capture CO2 from a cement plant in southwestern Ontario. It’s believed to be the first project of its kind in the world. Pond Biofuels, the three-year-old company that developed the processes and algae bioreactor technology behind the project, hopes to demonstrate that the system can be scaled up to accept the emissions from an entire plant or any other energy-intensive industrial facility. In the case of St. Marys, the algae will be harvested, dried using industrial waste heat, and then used to offset fossil fuels that are currently used in its cement kilns. In essense, the CO2 will be recycled over and over again. The company, which became a strategic investor in Pond Biofuels last year, is also investigating the idea of producing biodiesel from the algae that can be used to fuel its own truck fleet.

There are many algae technology companies out there, but it’s nice to see these two Ontario companies actually doing something outside of the lab in a way that directly meets the needs of industry. In fact, Pond Biofuels has its sights set on China as well. The company revealed in December that its St. Marys project had been approved as part of the Asia-Pacific Partnership on Clean Development and Climate program. This means it will get funding to do a feasibility study that will assess the suitability of its technology for the cement industry in China.

Attention all suppliers: Ontario Power Generation needs your wood pellets!

Thursday, March 18th, 2010

Ontario Power Generation issued a call today to potential suppliers of wood pellets to the Atikokan coal plant, which the utility plans to beginning converting to 100 per cent biomass burn in 2012. OPG requests that proponents provide pricing for a minimum volume that is between 22,500 and 30,000 tonnes (a year) and pricing for the entire 90,000 tonnes (a year) requirement,” according to the company’s ” request for indicative prices.”

In other words, it expects it will need 90,000 tonnes annually but wants to break this down into three our four chunks so it can have several suppliers. The final stage of conversion will begin in June 2012 and commissioning of the new equipment will likely start in August. OPG expects full-on commercial operation will happen by December. “The wood fuel pellet supply being considered under this RFIP will have a local content requirement such that the source of the wood fibre and the location of the production facilities that will produce the wood pellets shall be within Ontario,” according to the company. “OPG will require that the wood-based fuel pellets be accompanied by Chain of Custody Certification ensuring that the wood pellets supplied to OPG are manufactured from wood fibre sourced from well managed forests.”

In the Great Lakes St. Lawrence forest region of Ontario it’s estimated that there is about 1.475 million oven dry metric tons of wood fibre available for sustainable harvesting each year, or about 1.25 million if we take into account that some of the biomass will be used as fuel to dry the biofibre. So what OPG is requesting in this initial round is roughly 6 per cent of what’s available — and let’s not forget that pellets made of grass crops are also a potential source of fuel. Let’s keep in mind these converted coal plants will be used as peakers when using biomass fuel. This means there is plenty of biomass available for several units being targeted for conversion at the massive Nanticoke coal plant.

What we’re witnessing here is the beginning of the creation of an entirely new industry in Ontario developed around the need to economically harvest, pelletize and transport biomass fuel pellets to support the province’s coal phaseout strategy. This will create many jobs in parts of the province where jobs are needed most, and will establish a made-in-Ontario biomass fuel supply chain that can support the move to more distributed forms of biomass energy generation. There is plenty of opportunity here for entrepreneurs looking to play a role.

The Bloom Box: Am I missing something?

Monday, February 22nd, 2010

There’s much hype around the 60 Minutes segment Sunday night about Bloom Energy and its miraculous Bloom Box. I’m scratching my head wondering why this is such a big deal, so maybe someone can enlighten me. This to me seems like a fancy solid-oxide fuel cell system. It’s still super expensive, though Bloom claims that it can get the cost down to $3,000 (U.S.) for a residential unit. It still relies on fuel, such as natural gas, meaning it still produces CO2 emissions. Yes, far less emissions than burning that natural gas in a power plant and sending it via transmission lines to your home, but it’s not the emission-free miracle that 60 Minutes is touting. I didn’t hear much talk on the segment about whether the Bloom Box has a dual purpose: that is, electricity generation and heat production. And while it may replace the need for electricity lines coming into your home, you still need a natural gas line. In this sense, I can see tremendous interest from natural gas utilities looking to compete against electric utilities (a good parallel is how cable and phone companies over the years ended up offering the same services as technologies converged).

Perhaps there’s more to this story that wasn’t revealed by 60 Minutes, but there are many companies out there working on this kind of fuel cell so I don’t see what’s particularly special or unique about Bloom Energy. More details are expected to be released on Wednesday, however, so maybe then my questions will be answered.

In the meantime, would someone out there please enlighten me?

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.
