Ammonia as a Carbon-Free Fuel for Use in the Transportation Sector
The action plan lays out the specific commitments Ontario is making to meet its 15% overall greenhouse gas emissions reduction target by 2020. Emissions from total passenger transportation (cars, trucks, bus, rail and domestic aviation) have grown almost 15% since 1990, to 36 million tonnes of CO2e, approximately 66% of Ontarioâs 2014 transportation emissions. This growth was driven by an increase in vehicle-kilometres travelled as well as a shift in the composition of the fleet from cars to sport-utility vehicles, pick-ups and minivans where the specific contributions of the vehicle types are shown in Fig 1.
Fig. 1. Ontarioâs greenhouse gas emissions in 2014 (data from Ref. 1).
Here, it is important to note that under Environment and Climate Change Canadaâs economic sector categorization, most off-road transportation emissions are allocated to their host economic sectors and consequently are not included under transportation in Fig. 1. For example, emissions from diesel combustion in farm equipment are categorized under Agriculture. Therefore, in reality GHG emissions caused by the transportation vehicles are higher than 33% in Ontario.
Additionally, emissions from total freight transportation (trucks, rail and other) have increased more drastically over the period, rising 85% since 1990, to almost 18 million tonnes of CO2e (approximately one third of Ontarioâs current transportation emissions). This was driven by a significant increase in the use of diesel-fuelled heavy-duty trucks, with additional kilometres travelled offsetting improvements in efficiency .
This brief report tries to address the following points:
- Targets and blending requirements:
- Ontarioâs has existing content requirements for ethanol in gasoline. What minimum level of ethanol blending and GHG performance would help support the objectives of the RFS?
- Given Ontarioâs GHG reduction targets for 2030 and 2050, what factors should be considered in setting RFS targets post-2020?
- Flexibility mechanisms:
- Should activities to lower the carbon intensity of other conventional transportation fuels be eligible for compliance purposes?
- Should investments in low-carbon transportation projects also be eligible for compliance purposes? If yes, what types of projects?
- Assessing lifecycle emissions
- Should an RFS consider impacts from indirect land-use changes (ILUC),7 even though science in this area continues to evolve? If so, how?
- What measures can be taken to increase transparency and support business decision making under an RFS (e.g. an information registry, bulletins, guidance material)?
- What other considerations should be included in the discussion?
This report is primarily based upon three MITACS projects and several other location, feedstock or jurisdictionally based reports Hydrofuel Inc. has completed with the University of Ontario Institute of Technology (UOIT)
