Oil sands company Suncor Energy strengthens its focus on hydrogen and renewable fuels, divesting wind and solar

Green Car Congress

Suncor Energy, a Canadian integrated energy company that is one of the top oil sands producers in the country, will strengthen its focus on hydrogen and renewable fuels to accelerate progress towards its objective to be a net-zero company by 2050. Suncor also plans to divest its wind and solar assets.

Oil sands GHG lifecycle study using operating data finds lower emitting oil sands cases outperform higher emitting conventional crude cases; a call for more sophisticated tools and reporting

Green Car Congress

Well-to-wheel (WTW) greenhouse gas emissions for in situ SAGD and surface mining pathways generated employing GHOST/TIAX/ GHGenius combination and comparison with SAGD, mining and conventional crude oil literature pathways (all results are on a HHV basis). WTW emissions for pathways vary by more than ±10% (e.g.,

New lifecycle analysis of WTW GHG emissions of diesel and gasoline refined in US from Canadian oil sands crude

Green Car Congress

In a new, comprehensive study, a team from Argonne National Laboratory, Stanford University and UC Davis ITS has estimated the well-to-wheels (WTW) GHG emissions of US production of gasoline and diesel sourced from Canadian oil sands. g CO 2 e/MJ for US conventional crude oil recovery. This range can be compared to ∼4.4

U Calgary study finds oil shale most energy intensive upgraded fuel followed by in-situ-produced bitumen from oil sands

Green Car Congress

A team at the University of Calgary (Canada) has compared the energy intensities and lifecycle GHG emissions of unconventional oils (oil sands and oil shale) alongside shale gas, coal, lignite, wood and conventional oil and gas. Earlier post.).

New study finds GHG emissions from palm oil production significantly underestimated; palm oil biofuels could be more climate-damaging than oil sands fuels

Green Car Congress

When peat swamps are drained for agriculture, the peat begins to decompose, and is an enormous source of carbon emissions. Mha (20%) of the peatlands of Peninsular Malaysia, Sumatra and Borneo in 2010, surpassing the area of Belgium and causing an annual carbon emission from peat decomposition of 230–310 Mt CO 2 e.

Plot of cumulative steam-to-oil ratio (cSOR) vs. ratio of energy produced in form of chemical energy contained in bitumen if combusted to energy injected in form of steam (75% efficient steam generation). One of the key challenges in producing bitumen and heavy oil is their high, variable viscosity. From Gates and Larter (2013).

Researchers propose framework for CCS infrastructure optimization to reduce GHG emissions from oil sands extraction and processing

Green Car Congress

CCS infrastructure for six key CO 2 emission prices. The width of the pipeline network (green lines) is proportional to CO 2 flow; the largest CO 2 flow is approximately 36 MtCO 2 / yr for the $155/tCO 2 scenario (pipeline leaving the Athabasca oil sands area). Sources are red and sinks are blue. Costs are in $US 2011.
