Spotlight On Canada's Newest Anaerobic Digester At Ag-Forum

Posted by Lee Drever on Jan 9, 2015 3:47:59 PM

Seabreeze Biogas Tank
CH-Four Biogas used Octaform to form the concrete tanks of the new facility at Seebreeze Farm.

BC's newest anaerobic digester is now turning poop into power... and you can sign up for a site visit!

 

Seabreeze Dairy Farm in Ladner is now combining agricultural and non-agricultural waste to harness and utilize greenhouse gasses that would otherwise vent into the atmosphere. Under FortisBC's renewable natural gas program, this biogas is purified on site and injected into their natural gas system. 

Biogas Tank Construction
Assembly of the Octaform tanks began in the Spring of 2013.

This project will be spotlighted at the end of this month at the 2015 Agri-Energy & Waste Management Forum (January 30-31) in Abbottsford, BC. This forum will open on January 30 with a session focused on Seabreeze Farm and conclude with a site visit on January 31. Register Here!

Introducing the 2015 Agri-energy & Waste Management Forum

Renewable energy and waste management technologies enable you to take advantage of underutilised resources, diversify income, manage waste, and reduce costs. The 2015 Agri-energy & Waste Management Forum will enable you to increase your understanding of renewable energy and waste management technologies relevant to your farm or agricultural operation.

Also, don’t miss your chance to see BC’s newest anaerobic digester. Sign-up to book your place on the site visit bus today! The site visit will include a free bbq lunch, coffee and tea. Buses will leave from in front of TradeX (1190 Cornell St, Abbotsford). The site visit costs only $20.00!

Concrete Biogas Tank
The Agri-Energy & Waste Management Forum will provide an opportunity to hear from the technology providers and contractors that worked together to build the new Seabreeze digester. 

Anaerobic Digestion Session 1: Seabreeze Farms
January 30, 9:30am - 11:00am

Building an anaerobic digester involves many different technologies and local contractors. Through rapid-fire presentations, learn about some of the technologies and contractors that have contributed to Seabreeze Farm’s anaerobic digester in Delta. These presentations will provide useful background information for the Seabreeze Farm site visit on January 31st.

Chair: David Melnychuk (Agricultural Consultant, Langley).

Tweeting the Biogas to Biomethane Workshop

Posted by Christina Florencio on Nov 2, 2011 4:40:00 PM

Fortis BC recently held a free workshop titled “Biogas to Biomethane: Renewable natural gas development in B.C.”.  The event was targeted to those interested in learning from technology suppliers, industry experts and Fortis BC to gain a better understanding of B.C.’s renewable natural gas potential, how project developers can contribute to developing renewable and sustainable energy in B.C.

The Octaform team attended the full day workshop covered a wide variety of topics including:

  • The current state of the Biomethane industry
  • B.C.’s regulatory framework for supply
  • Biomethane supply opportunities for FortisBC’s renewable natural gas offering
  • Technology provider presentations from: Xebec, Greenlane Flotech, and Purac
  • Feedstock considerations presented by:  Green Tech Avenue             
  • Case Studies presented by: MT Biomethan and Deep Blue NRG

With approximately 50 attendees to the workshop, the audience ranged from local farmers, to civil engineers to representatives from financial institutions. We tweeted live from the event to give our followers a real time update on insights shared:

  • Greenlane Biogas: a provider of #Biogas upgrading technology.

  • Purac Puregas is a part of Läckeby Water Group. They offer contracting, products and servicing for #biogas production. #FortisWorkshop

  • Amine washing achieves a methane purity of 99 % and methane loss of less than 0.1 %. #Biogas #FortisWorkshop

  • Electricity and gas prices expected to remain flat through 2020 while diesel continues to rise. #Biogas #FortisWorkshop

  • Biomethane project requirements: Utility agreement, Offtake contracts, Transportation agreement, Financing. #Biogas #FortisWorkshop

Biogas Upgrading Comes to Small-Scale Farms

Posted by Lee Drever on Aug 30, 2011 9:15:00 AM

The anaerobic digestion process solves two big problems by creating energy from waste. The simplest way for a small-scale agricultural operation to do this has been to use the biogas derived from the digester to fuel a generator, pumping electricity onto the farm and surplus energy back on to the grid.

Large-scale operations have also had the option to invest in upgrading equipment and sell to utilities companies like Fortis in British Columbia. In its raw form, biogas contains other gases not compatible with natural gas. Upgraded or "scrubbed" however, it becomes biomethane or renewable natural gas. This process has been cost-prohibitive for a small-scale operation but a company in Sweden is hoping that their upgrading technology will fill that niche.

Artic Nova has developed a small-scale upgrading system called BioSling, making it possible for farmers to turn their waste into fuel for their (and even their neighbour's) vehicles. Suitable for operations with as few as 200 cows, BioSling is a flexible alternative to simple electricity generation.

Small Scale Biogas UpgradingCoils of plastic hoses constitute the main component of BioSling. The vessel shown in the background accumulates the upgraded gas and separates it from water saturated by carbon dioxide.

The system is contained in a standard 24ft container consisting of a control room and an upgrading room. Rotating coils of plastic hosing force the raw biogas in contact with water, effectively scrubbing the gas of impurities and carbon dioxide increasing the methane content to 94 per cent. Biogas of this purity is ideal for for farm equipment and converted spark ignition or diesel engines.

Further scrubbing is possible (and required) to send natural gas to the grid but excess is easily stored in pressurized cylinders.

Is it expensive? Sure, but if renewable energies are to become a real alternative, investment will is required. Many European countries are already leading the way with subsidies for green technologies. As energy prices increase in North America, the will to do the same is starting to appear and consumers do seem eager to support renewable energies.
