From Banana Peels and Leaves to Heat and Electricity

Is it viable to turn food and yard waste into renewable energy for heating buildings and providing them with electricity? That’s what Yukon Energy is currently looking into, through a partnership with the Cold Climate Innovation Program of the Yukon Research Centre. It’s the first project of its kind ever tried in Yukon. This week, representatives from both companies spent time at the Whitehorse compost site collecting two 55-gallon drums full of organics; one barrel of food waste and the other of yard waste. The material has been sent to Saskatchewan where there will be a trial done to find out how much energy (biogas) can be produced with the organics. The organic mixture, in various ratios of yard versus food waste, will have microbes added to it, and will then be put in a chamber and sealed so no oxygen can get at it. It’s heated to 38 degrees Celsius and left to ‘cook’ for 30 days. During the trial, biogas is produced and collected. Scientists will measure the amount and composition of the biogas and they’ll analyze the chemical characteristics of our organics before and after the testing. This information will give Yukon Energy a good idea of how much biogas could come from Whitehorse’s organic waste. Currently there’s approximately 2,200 tonnes of yard and food waste going to the Whitehorse landfill each year, although that is expected to increase as the City of Whitehorse moves forward with its enhanced diversion plans. The next step of this study is to do a financial analysis to find out if this method of renewable energy production would be economically viable. It's important to note that if this does move ahead as a bigger scale project, the food and yard waste used to generate heat and electricity would go on to be composted as it is now. This project would in no way reduce the amount or quality of compost generated at the landfill site.

Thermal Back-up Proves to be Life Line

We are making good progress in getting rid of the ice causing problems for our Whitehorse hydro units. Yesterday afternoon we managed to get our largest Whitehorse hydro generator back on line, and this morning only had to use a small amount of Whitehorse diesel generation to help meet the morning peak. At the time this is being written (noon), we are not running any diesel at all. Divers are still working to clear the ice from the trash racks (metal grates that prevent debris from getting into our turbines) for our three other Whitehorse hydro units. We expect they will be back in operation later today. The problems began on Saturday night, when mild temperatures and high winds caused slushy sheet ice to break away from the shoreline of Schwatka Lake. The ice attached itself to the trash racks of all four of our hydro generators. We were forced to burn a substantial amount of back-up diesel to meet the demand for electricity. This is an example of why Yukon needs thermal back-up. While it’s desirable to not use diesel or natural gas for generation, in a case like this, it was a life line. We lost hydro capacity at our largest hydro generating facility, and yet no one lost their power.  Yukon Energy spent about $192,000 on diesel over the last few days. If the two natural gas units had been in operation, we would have saved at least $34,000 for those three days alone. Here are some photos of the work that's going on to de-ice our trash racks.
