There was a big stink this week when a published study, led by University of Virginia civil engineering professor Andres Clarens, concluded that producing biofuels from algae isn’t as climate-friendly as many people believe, at least when compared to getting biofuels from switchgrass, canola, and – Huh? — even corn. The results, according to an abstract of the study, “indicate that these conventional crops have a lower environmental impact than algae in energy use, greenhouse gas emissions, and water regardless of cultivation location.” Why? Because of the need to supply more nutrients — i.e. fertilizer — to algae to stimulate growth, and fertilizer is energy-intensive to produce.

The problem with this conclusion? Clarens based the life-cycle analysis on data that was mostly 10 years old. For example, some current algae cultivation practices, particularly those based on wastewater or sea water, tackle the fertilizer issue head on. So the age of the data is an important bit of information that should have been made very clear in the study — even the abstract. Ten years in the world of technology, particular cleantech, is a long time. I mean, the big R&D push around algae-based fuels only began three or four years ago, and 10 years ago the “cleantech” sector didn’t exist in name. Ten years ago the world was still wrapping its head around Y2K, George W. Bush was just getting into office, Google was still a start-up years from going public, and the TV show CSI (the original one) had its world premiere. In other words, you can expect data about algae cultivation to be, well, rather useless as a reflection of current practices.

This isn’t to blame Clarens. As he told the New York Times’ Green Inc., the most current data out there is simply unavailable to academia. It’s proprietary. (more…)

Algae or enzymes? That is the question. Both are moving forward as an approach to capturing CO2, and both are getting funding. Quebec City-based CO2 Solution announced last week that Codexis Inc. acquired a 17-per-cent stake in the company for $2 million. The two companies have signed a joint development agreement whereby they will collaborate on the use of “enzymatic carbon capture” technology.  CO2 Solution has developed a process that relies on the enzyme carbonic anhydrase to extract carbon dioxide from the smokestacks of coal power and industrial plants. This particular enzyme is used by humans and other mammals to extract CO2 from the blood stream that is later exhaled. Codexis brings to the table a way to improve the ability of this enzyme to thrive in harsh industrial environments. The companies are betting that this approach will be less energy-intensive and therefore less expensive than other solutions in development or on the market.

Meanwhile, Toronto-based Pond Biofuels Inc. says one of its CO2-to-algae demonstration projects has been approved as part of the Asia-Pacific Partnership on Clean Development and Climate program. The company, in partnership with cement manufacturer St. Marys Cement, has established a microalgae facility that uses CO2 from the neighbouring cement plant as a source of nutrients for the organisms. The algae is then expected to be harvested and used as biomass fuel in the plant’s cement kiln. Pond Biofuels will now get funding under the Asia-Pacific Partnership for a feasibility study that will assess the suitability of its technology for the cement industry in China.

I’ve got a lengthy feature in the Toronto Star this weekend about the recent wave of activity around algae as a source of renewable fuel. Now, in the past there has been no shortage of algae-to-biofuel startups — some have already failed, others have managed to raise money and continue to work away. But the new wave of startups — Algenol Biofuels, Catilin, Synthetic Genomics and others — have two things going for them. One, they’re overcoming one of the biggest economic obstacles, which is the difficulty and cost involved with harvesting algae so that they can be processed for their oils. Instead, these new startups are developing strains of algae that continuously produce and actively secrete oils and ethanol. By turning the algae cells themselves into microscopic refineries, several process steps can be eliminated along with costs. Second, these startups are also hooking up with some big partners in industry to demonstrate that their technologies can be scaled to a size that matters. Algenol has hooked up on a massive demonstration project in Texas with Dow Chemical, while Synthetic Genomics (Genomics pioneer Craig Venter’s company) recently snagged $300 million in funding from ExxonMobil, which has committed $600 million to algae fuel R&D and says it will contribute billions of dollars more if efforts over the next few years prove successful. Honeywell, by the way, is leading the charge in turning algae oils into green jet fuel, and it’s working with Boeing, Airbus and several major airlines to make it happen. Dow, Exxon, Honeywell — these are no corporate pansies. These are serious companies putting flesh in the game.

My feature, by the way, starts out focusing on Florida-based Algenol. Many don’t realize the company’s technology emerged out of research at the University of Toronto, and that founder Paul Woods is a Canadian who was born, grew up and ran a natural gas marketing business in Toronto before heading south at age 36. Algenol’s chief science officer, John Coleman, is the U of T professor who worked with Woods over the past 25 years to perfect the Algenol process.

I’ve said this in many posts before, but I’ll say it again: These are exciting times people. The engine of innovation is in high gear.

I had a feature this weekend in the Toronto Star about the cap-and-trade system coming to Ontario and the likelihood an offsets market will be created a year or more before the 2012 launch of the program. The government here is working hard to align our own provincial system with the Western Climate Initiative, in which it is a member, as well as the Waxman-Markey bill under consideration in the United States (which will likely set the North American standard). The idea of allowing a carbon offsets market to emerge in advance of the cap-and-trade launch is a smart one, as it gives industry a way to prepare and it stimulates offset project development before the final cap-and-trade rules go into effect.

But here’s the problem: A good portion of offset projects are also electricity generation projects, such as wind, solar, biogas and hydroelectric. But in Ontario, if you want to sell your electricity to the power authority you sign a 20-year deal under a new feed-in tariff program. The tariffs are generous, but most developers are also hoping to keep the carbon credits they would qualify for so they can be sold as offsets.

Unfortunately for them, the Ontario Power Authority’s contract for power purchases stipulates that it — and by “it” I mean the Ontario government, which is ultimately the Ontario ratepayer — gets to keep all environmental attributes. This raises a number of issues: (more…)

Toronto-based RuggedCom continues to defy the economic downturn and prove the smart grid is the market to be in by posting a 52 per cent increase in fourth-quarter revenue and 49 per cent increase in same period profits. For the fiscal year, the company’s profit jumped 154 per cent. The company’s annual revenue now tops $60 million, 63 per cent of which is coming from the utility industry through sales of smart-grid networking gear. Find me another company that has seen its stock value jump 75 per cent higher than what it traded at just before the October 2008 market crash. RuggedCom is indeed a rare bird. It’s why I’m always amazed to see the U.S. media ignoring this story. There is so much attention to Cisco getting into the smart grid that nobody has noticed that little RuggedCom leads the market in the sale of networking equipment for the grid, or that RuggedCom plans to leverage that leadership position and expand its presence throughout other aspects of grid modernization. In fact, I wouldn’t be surprised if Cisco is doing its due diligence on RuggedCom as a possible acquisition. It fits the Cisco purchase profile, and compared to other smart-grid plays its P/E ratio isn’t that rich.

Another company that’s overlooked by U.S. media is Ottawa-based Cyrium Technologies, which just announced record performance from its commercially manufactured multi-junction solar cells, which are based on quantum dot technology. “Cyrium’s first generation solar cells offer efficiencies of 40 per cent or higher together with a nearly constant conversion efficiency for solar concentrations from 200 to greater than 1,000 suns,” the company said. This is a big deal, given that the other “records” touted to date, which range from 40.8 to 42.8 conversion efficiency (these claims are in dispute — see Wikipedia entry), have been limited to the lab. Cyrium, on the other hand, is actually manufacturing limited quantities of its cells for testing by potential customers. And the company isn’t resting on its laurels, either. “Cyrium anticipates its second generation product will reach 43 per cent efficiency within one year and third generation products are targeted to be at 45 per cent within two years,” the company said.

Meanwhile, Montreal-based Enerkem has been granted a permit to commence construction of what it’s calling the “world’s first commercial municipal waste-to-biofuels facility.” The $70 million facility, located in Edmonton, Alberta, will take municipal solid waste that’s left over after recycling and composting and will convert that waste into ethanol using Enerkem’s process. The project is a joint-venture between Enerkem (technology supplier) and Greenfield Ethanol (ethanol producer). “This unprecedented project is set to change the dynamics of the waste and fuel industries by making waste — that would otherwise be landfilled — a resource for transportation fuels,” said Enerkem CEO Vincent Chornet. I know I won’t be the only one following this project closely.

Finally, honorable mention goes to Toronto-based WhalePower, which has just made it as a finalist at the prestigious INDEX international design competition in Copehagen, Denmark. You may recall WhalePower’s new wind-turbine blade design, which is inspired by the humpback whale’s tubercle-line flipper. This bumpy leading edge gives the whale more agility in water. WhalePower has adapted the design to turbine blades, allowing for more efficient capture of wind energy and access to this energy at lower speeds. There are five categories in the Copenhagen competition, and the winner of each category gets 100,000 Euros. Winners will be selected in August and the winning designs will also become part of a touring show through Asia and Europe. WhalePower is competing in the “community” category against some tough competition, including Shai Agassi’s Better Place.

But enough with the bragging Canuck — let’s end on a more negative note. (more…)
