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.

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.

Wisely, airline industry continues move toward green jet fuel

Sunday, February 21st, 2010

I’ve always said that if we are to pursue a biofuels strategy, it should first and foremost focus on developing renewable fuels for airplanes. Using batteries or fuel cells to power a large passenger jet is a non-starter, given the added weight to the aircraft. We can electrify most ground transportation, but we can’t electrify airplanes, so biofuels is what we’re left with if we want to reduce the carbon footprint of the airline industry.

There’s no question that biofuels are controversial, particularly when we talk of growing corn and other food crops as a feedstock for producing ethanol and other green fuels. There’s much potential in second- and third-generation biofuels, using wood, agricultural, and municipal wastes and algae, but there’s considerable doubt that even these non-food feedstocks could allow us to make a meaningful dent in our fossil-fuel consumption. This is why targeting the airline industry makes sense. It only represents about 12 per cent of global petroleum consumption, so maybe we can serve this market with the non-food feedstocks we have.

Momentum in this area continues. Last week British Airways announced a partnership with U.S.-based Solena Group, which plans to build the first commercial plant in Europe dedicated to producing jet fuel from municipal solid waste — everything from food waste to grass cuttings. The waste will be turned into syngas using a plasma-arc process, and that gas will form the basic chemical building blocks for the green jet fuel.

Joshua Kagan over at Greentech Media has a good update on this trend.

100% coal-to-biomass conversion reduces GHGs by 92 per cent: study

Monday, February 1st, 2010

Ontario is making solid progress with its plan to convert some of its coal-fired power plants to biomass. And not just co-firing, like what many U.S. jurisdictions are considering, but full out 100 per cent biomass burn. It will prove a key part of Ontario’s greenhouse-gas reduction strategy. A new University of Toronto study has concluded that converting coal-fired units at the Nanticoke and Atikokan plants to burning wood pellets would reduce GHGs by roughly 92 per cent, and this is based on a full lifecycle analysis. On top of that, it would create a local biomass supply chain — for harvesting, pelletization, transportation, etc. — and local jobs that simply don’t exist under a coal-only regime. OPG also plans to operate the plants as peakers, meaning they could be used to help manage renewables (i.e. there would be less natural gas required to perform this balancing act).

I have an update on Ontario Power Generation’s biomass strategy in today’s Clean Break column. OPG will likely convert Atikokan to 100 per cent biomass by 2012, with some units at Nanticoke likely to follow a year later. Lambton and Thunder Bay plants are also being considered. The OPG executive heading up the transition, Chris Young, says the company is seriously investigating a fuel pellet mixture with both wood and agricultural residues (or dedicated crops, like switchgrass). OPG figures that coal plants converted to burning biomass will likely operate for another 10 years before decommissioning, at which point the pellet supply chain will be firmly established and the move to build a distributed fleet of newer biomass-burning plants can begin.

And what is U of T’s estimated cost of supplying electricity from an existing coal plant converted to burning 100 per cent biomass? Roughly 12 cents per kilowatt-hour, which excludes the impact of carbon prices. Given that natural gas won’t stay low forever and will eventually be subject to carbon pricing, this makes the biomass option competitive (also with wind and nuclear) and at the same time is a winner when it comes to local green-collar job creation.

If OPG can pull this off, it would be another Ontario first — and something other jurisdictions can learn from.
