Portrait of Maryam Akbari

Abstract: Renewable natural gas (RNG) can be produced from different biomasses through gasification, supercritical water gasification (SCWG), pyrolysis, and anaerobic digestion (AD). For the development of a commercial scale RNG production plant from biomass as feedstock, assessing the cost of production of RNG is necessary. In this study, comprehensive data-intensive techno-economic models are developed to calculate RNG production cost ($/MJ) from thermochemical and biological conversion processes using forest and agricultural biomass feedstocks. The results provide new information for policymakers and companies as they can draw insights for the technology transitions that they may need to consider meeting climate change goals.

Abstract: To meet the challenge of climate change, Quebec has embarked on a major energy transition. This transition requires the electrification of the economy, but also the development of hydrogen and bioenergy. Renewable natural gas, a low-carbon gas produced locally, is ideal for "greening" uses where electrification is more difficult. To ensure the development of this new industry, the Quebec government has adopted structuring tools, both in terms of regulations and support programs for producers. The outline of this plan will be presented to you.

Portrait of Sophie Chainel

Abstract: Twelve French farmers had decided to pool their stockpiles of manure and other organic waste to serve as a resource for biogas production. Prodeval used its Valopur® technology to help them set up a compact, economical production unit, which simply connected to the methanation units already in place without any change to operations. The technology allows for the repurposing of a portion of the biogas generated by the anaerobic digestion of agricultural waste. The Méthamoly project effectively met 40% of the regional needs in its first year of implementation. Thrilled with the results, the farmers opted for Prodeval’s first CN’Green® unit in September 2020, enabling them to convert RNG into CNG and supply biogas to the region’s waste collection trucks.

Portrait of Sahar Kamali

Abstract: Who CE is and what is Redeem RNG? How we generate supplies of RNG with partners like BP across Canada and the US - examples of current Canadian and US suppliers. Who are the RNG suppliers we want to partner with? Our growth trajectory – Sold over 500 M DLE’s across North America in 2019 and anticipate that there will be very significant supply and demand increases as individual Canadian provinces (like BC already has) and/or the federal government introduce low carbon fuel standards/carbon taxes similar to what states like California and Washington and the US government have in the US. The relative value of zero or negative CI RNG and how this will be a game changer as a financially and operationally superior and equal or better environmental alternative or complement to battery powered buses and commercial trucks NOW and for the foreseeable future without even considering the dirty secret associated with the production and disposal of large battery packs. Why governments at all levels need to recognize that the production and use of RNG for on-road transportation is the highest and best use of RNG, a boon to the circular economy high paying job creator. In closing, an exciting opportunity for clean fuel diversity that will allow Canada and Canadians to meet environmental goals without betting the farm (and its RNG production) on one technology – flavour of the day battery buses and commercial vehicles (How many nuclear plants do we want to build to provide the power these vehicles will need and who is going to pay for it?)

Portrait of Erika Winquist

Abstract: In Finland, the total biomass energy potential available for biogas production, not competing with food production, is estimated to be 10 200 GWh (Marttinen et al., 2015). Most of this potential is in agriculture (grass and straw 72%, manure 14%), and the rest in pulp and paper sludge (6%), food industry waste (3%), municipal biowaste (3%) and sewage sludge (2%). However, only ca. 800 GWh of energy was produced from biogas in 2018. A significant potential to increase biogas production lies in agricultural residues and local farm-scale plants. The study shows on example of a farm-scale leaching bed digester. Grass silage from green manure leys was used for biogas production together with horse and chicken manure. The aim of the study was to follow up a new type of farm-scale bioreactor, a leach bed reactor, and evaluate its suitability and efficiency for energy production and nutrient circulation on the farm.

Biography: Erika Winquist works as Senior Scientist in Natural Resources Institute Finland (Luke), Biorefinery and Bioproducts research group. She has several research interests all related to circular economy such as sustainable and resource efficient use of agricultural biomasses, and production of biogas and recycled nutrients.
