Another workbook in the Abundance series.

It revolves around the idea of Canada to supply Natural Gas as Liquified Natural Gas (LNG) to China, with goals (fro9m the perspective of this workbook):
 - help China reduce amount of coal it uses,
 - help Canadaian economy,
 - be popular in Alberta,
 - make sense re climate change
The final goal is for both countries to be completely off fossil fuels as quickly as possible.

What about Chinese-made electric vehicles?
What is the current status of the pipeline from Alberta to an ocean terminal in BC?
A key issue for people, is being able to trust all parties to follow through as fast, efficiently as possble to phase out all fossil fules.

### TODO
- define the details of this model
 - work out how it makes sense re climate change
  - work through a scenario with a time frame that shows net reduction in CO2
-

>>> Canada has built a LNG pipeline from Dawson Creek to Kitimat. Please summarize this project.

Okay, let's break down the Canada LNG pipeline project, officially known 
as the **Coastal GasLink (CGL) Pipeline**. Here's a summary, covering 
its purpose, route, construction, controversies, and current status:

**1. What is it & Why was it Built?**

*   **Purpose:** The Coastal GasLink pipeline is designed to transport 
natural gas from the resource-rich Montney region in northeastern 
British Columbia (centered around Dawson Creek) to a liquefied natural 
gas (LNG) export facility near Kitimat on the British Columbia coast.
*   **Part of a Larger Project:** It's a critical piece of the massive 
**LNG Canada** project, a joint venture between Shell, Woodside Energy, 
Chevron, and Mitsubishi Corporation. LNG Canada takes the natural gas 
delivered by CGL, liquefies it, and ships it overseas, primarily to 
Asia. The goal is to access international markets for Canadian natural 
gas.

**2. The Route & Specifications:**

*   **Length:** Approximately 670 kilometers (416 miles).
*   **Route:** It starts near Dawson Creek and travels through the Rocky 
Mountains, crossing numerous rivers and passing near indigenous 
communities.  The route was subject to significant review and 
modification to minimize environmental and social impacts (more on that 
below).
*   **Diameter:**  Primarily 914 mm (36 inches) in diameter.
*   **Capacity:** Designed to transport approximately 4.5 billion cubic 
feet per day (Bcf/d) of natural gas.

**3. Construction & Timeline:**

*   **Approved:**  The project received provincial approval in 2018 and 
federal approval in 2019, following extensive reviews and consultations.
*   **Construction Start:** Construction officially began in December 
2019.
*   **Challenges & Delays:** The project faced significant delays and 
cost overruns, primarily due to:
    *   **Indigenous Opposition:**  Significant opposition from some 
First Nations (more detail below).
    *   **COVID-19 Pandemic:**  Disruptions to supply chains and 
workforce availability.
    *   **Environmental Concerns:**  Requirements for additional 
environmental protection measures.
*   **Completion & Operation:**  The pipeline was mechanically complete 
in December 2023.  Natural gas began flowing through the pipeline in 
October 2024.

**4. Controversies & Opposition:**

*   **Wet'suwet'en Hereditary Chiefs & Land Defenders:**  The most 
significant controversy revolves around the pipeline's route through 
Wet'suwet'en traditional territory.  The Wet'suwet'en Hereditary Chiefs 
have asserted their rights and title to the land and have not consented 
to the pipeline's construction.  This has led to blockades, protests, 
and legal challenges.
*   **Indigenous Consultation:**  The adequacy of the consultation 
process with Indigenous communities was a major point of contention. 
Critics argued that the process was inadequate and did not meaningfully 
address the concerns of Wet'suwet'en and other First Nations.
*   **Environmental Impacts:** Concerns were raised about potential 
impacts on water resources, fish habitat, and wildlife, particularly 
during construction and operation.
*   **Climate Change:** Opponents argue that the pipeline and LNG Canada 
contribute to greenhouse gas emissions and exacerbate climate change.

**5. Current Status & Significance:**

*   **Operational:** The pipeline is now operational and transporting 
natural gas.
*   **Economic Impact:** The project is expected to generate significant 
economic benefits for British Columbia, including jobs, tax revenue, and 
investment.
*   **Ongoing Tensions:**  Despite the pipeline's completion, tensions 
remain with some Wet'suwet'en communities, and the issue of Indigenous 
rights and consultation continues to be a sensitive and complex one.
*   **Symbolic Importance:** The Coastal GasLink pipeline has become a 
symbol of the broader tensions surrounding resource development and 
Indigenous rights in Canada.

>>> Why does the pipeline move natural gas rather than LNG?
You're asking a very astute question that highlights the difference 
between the pipeline's function and the overall project goal! Here's the 
breakdown of why the pipeline moves natural gas and not LNG:

**The Pipeline's Job: Transportation**

*   **Natural Gas is the Raw Material:** The Coastal GasLink pipeline’s 
*primary* role is to transport **natural gas in its gaseous form**. It's 
a transportation infrastructure project. Think of it like a highway for 
natural gas. It gets the gas from the production fields to the LNG 
facility.
*   **Pipeline Limitations:** Natural gas is a gas at normal 
temperatures and pressures.  LNG (Liquefied Natural Gas) is natural gas 
that has been cooled to -162°C (-260°F). This process turns the gas into 
a liquid, which is much denser and easier to transport in large volumes. 
 Pipelines are not designed to handle LNG; they'd need specialized, 
extremely cold-resistant infrastructure, which would be incredibly 
expensive and complex.

**LNG Canada's Role: Liquefaction & Export**

*   **Liquefaction Process:** At the LNG Canada facility in Kitimat, the 
natural gas arriving via the Coastal GasLink pipeline undergoes a 
process called **liquefaction**. This involves cooling the gas to 
extremely low temperatures, transforming it into LNG.
*   **Shipping LNG:** It's the LNG – the liquid form – that is then 
loaded onto specialized ships and exported to international markets.



**Think of it this way:**

*   **Coastal GasLink Pipeline:**  Moves *natural gas* (the raw 
ingredient).
*   **LNG Canada Facility:**  Takes the natural gas, liquefies it, and 
prepares it for export as LNG.

The pipeline is a crucial link in the chain, but it's only one part of the larger LNG export process.

>>> Is natural gas the same as methane?
That's a great question, and it gets to a bit of a nuance in 
terminology. Here's the breakdown of the relationship between natural gas and methane:

**Methane (CH₄) is the *primary* component of natural gas.**

Let's break it down further:

*   **Methane:** This is a chemical compound – a molecule made up of one 
carbon atom and four hydrogen atoms. It's a gas at room temperature and 
pressure.
*   **Natural Gas:** This is a *mixture* of gases that is found 
underground. The vast majority (typically 70-90%) of natural gas is 
methane (CH₄). However, it also contains smaller amounts of other gases, 
including:
    *   **Ethane (C₂H₆)**
    *   **Propane (C₃H₈)**
    *   **Butane (C₄H₁₀)**
    *   **Carbon Dioxide (CO₂) - a small amount**
    *   **Nitrogen (N₂) - often present as a contaminant**
    *   **Trace amounts of other hydrocarbons**

**So, while natural gas is *primarily* methane, it's not *just* 
methane.** It's a mixture, with methane being the most abundant and 
commercially valuable component.



**Think of it this way:**

*   **Methane is like the main ingredient.**
*   **Natural gas is the finished dish (that contains the main 
ingredient, but also a few others).**

>>> In the pipeline project, how much natural gas leaks into the air at each step of the process?

Okay, quantifying natural gas leaks across the entire process – from 
wellhead to export – is complex and a topic of ongoing scrutiny and 
reporting. There's no single, definitive number, as leak rates vary 
depending on technology, maintenance practices, and regulatory 
oversight. However, I can give you a breakdown of where leaks occur and 
estimates of the leakage rates at each step, based on available data and 
industry reports.

**1. Upstream (Production & Gathering - Dawson Creek Region):**

*   **Source:** This is where most of the leakage occurs. It involves 
wells, processing plants, gathering pipelines, and compressor stations.
*   **Leak Sources:**
    *   **Well Sites:** Venting and flaring (intentional release of 
gas), leaks from equipment.
    *   **Processing Plants:** Equipment leaks, incomplete combustion 
during processing.
    *   **Gathering Pipelines:** Leaks from pipelines, compressor 
stations, and meter stations.
*   **Estimated Leakage Rate:** Estimates vary widely. Older figures 
suggested a potential rate of around 2-3% of total gas produced. More 
recent estimates, influenced by stricter regulations and improved 
technology, place it closer to 1-1.5% but can spike during maintenance 
or incidents. The BC Oil and Gas Commission (now the BC Energy 
Regulator) has been working to lower these rates.
*   **Specific to CGL:** Direct data specific to the Coastal GasLink 
pipeline's upstream section is difficult to obtain, but it’s likely 
influenced by the average rates for the region.

**2. Coastal GasLink Pipeline Transportation:**

*   **Sources:** Leaks from pipeline sections, compressor stations 
(required to maintain pressure), and meter stations.
*   **Leakage Rate:** CGL has committed to a leak detection and repair 
program. The pipeline's design incorporates advanced leak detection 
technology. CGL's publicly stated commitment is to operate the pipeline 
with a methane intensity below 0.2%. The industry average is around 
0.3%. It's important to note that "intensity" is typically expressed as 
a ratio of methane emissions per unit of gas transported, rather than a 
percentage of the total gas volume.
* **Challenges in Monitoring**: Given the remote nature of some sections 
of the pipeline, accurately quantifying leaks can be challenging.

**3. LNG Canada Facility (Kitimat):**

*   **Sources:** Leaks from liquefaction equipment, storage tanks, and 
loading facilities. Venting and flaring during maintenance and 
emergencies.
*   **Leakage Rate:** LNG facilities are subject to strict environmental 
regulations, but leaks are still a concern. Similar to the pipeline, LNG 
Canada has committed to best practices and aims to minimize methane 
emissions.  However, the liquefaction process itself is inherently 
energy-intensive and can generate methane emissions.
*   **Recent Developments:** Shell, one of the major partners in LNG 
Canada, has publicly committed to reducing methane emissions across its 
operations, including at the Kitimat facility.

**Overall Estimates & Challenges:**

*   **Total Methane Emissions:** It’s challenging to provide a single, 
comprehensive figure for the entire process. Estimates suggest that the 
entire LNG Canada project, from production to export, could potentially 
release several tens of thousands of tonnes of methane annually.  The 
exact amount depends on the factors mentioned above.
*   **Underreporting Concerns:** There's ongoing debate about whether 
methane emissions are consistently and accurately reported by the oil 
and gas industry. Some studies suggest that reported emissions may be 
significantly lower than actual emissions.
*   **Importance of Measurement Techniques:**  Accurate measurement of 
methane emissions is crucial for understanding and mitigating the 
problem.  Scientists are using various techniques, including satellite 
monitoring, aerial surveys, and ground-based sensors, to improve 
measurement accuracy.

**Disclaimer:** Estimating leakage rates is inherently complex, and the 
numbers provided above are approximate. Ongoing monitoring, 
technological advancements, and stricter regulations are continuously 
impacting these rates.

>>> How much of the natural gas in the Dawson Creek area produced using fracking?

Okay, let's break down how much of the natural gas produced in the 
Dawson Creek area relies on hydraulic fracturing (fracking). It's a very 
high percentage – essentially, the vast majority.

Here's a detailed explanation:

**The Montney Formation – The Key Player**

*   **Dawson Creek's Production Hub:** The Dawson Creek region is at the 
heart of the Montney Formation, one of Canada’s largest and most 
prolific natural gas resource areas.
*   **What is the Montney?** The Montney is a shale formation – a layer 
of sedimentary rock with very low permeability (meaning gas can't flow 
through it easily). It contains huge reserves of natural gas, along with 
some oil and condensate.
*   **Conventional vs. Unconventional:** Historically, some natural gas 
in the region was produced using conventional methods (where gas flows 
relatively easily through the rock). However, the vast majority of the 
gas potential in the Montney is considered *unconventional*, meaning 
it's trapped within shale rock and requires specialized extraction 
techniques.

**The Role of Fracking**

*   **Essential for Production:** To unlock the gas trapped in the shale 
rock of the Montney Formation, hydraulic fracturing (fracking) is 
*essential*. Without fracking, virtually none of the gas in the play 
would be economically recoverable.
*   **How Fracking Works (briefly):** Fracking involves injecting a 
mixture of water, sand, and chemicals under high pressure into the shale 
rock, creating fractures (cracks) in the rock that allow the gas to flow 
more freely to a wellbore.
*   **Dominance of Fracking:** Estimates suggest that **over 95% of the 
natural gas produced in the Dawson Creek/Montney area is extracted using 
fracking techniques.** Some sources even state it’s closer to 98-99%.

**Supporting Data Points**

*   **BC Oil and Gas Commission/BC Energy Regulator Reports:**  These 
reports consistently highlight the reliance on unconventional gas 
production in the Montney region. Their data show the overwhelming 
majority of new wells and production comes from shale gas formations.
*   **Industry Reports:** Reports from industry organizations like the 
Canadian Association of Petroleum Producers (CAPP) also confirm the 
dominant role of fracking in the region's natural gas production.
*   **Well Type Distribution:** Analysis of the types of wells being 
drilled in the Dawson Creek area consistently shows a very high 
proportion of shale gas wells, which require fracking.

**Key Takeaway:** The Dawson Creek area’s natural gas production is almost entirely dependent on hydraulic
fracturing to access the 
resources locked within the Montney Formation.

>>> Assume that all of this LNG is shipped to China. Compare two scenarios in 
... terms of greenhouse gas (carbon dioxide and methane) emissions. Scenario 1
... : natural gas and LNG from Dawson Creek, to Kitimat, to China. Scenario 2:
...  mine coal in China. In both scenarios, the fuel is burned to produce heat
... .

Okay, let's analyze the two scenarios – Dawson Creek LNG to China versus 
Chinese coal mining for heat production – comparing their greenhouse gas 
(GHG) emissions. This is a complex comparison with a lot of variables, 
so I'll break it down into components and then provide a relative 
comparison.

**Scenario 1: Dawson Creek LNG to China**

*   **A. Upstream Emissions (Dawson Creek to Kitimat):**
    *   **Natural Gas Production & Processing:** Significant methane 
emissions (leakage) during extraction, processing, and transportation. 
(Estimate: 1-3% of gas produced, as discussed earlier).
    *   **Coastal GasLink Pipeline:** Methane leakage from pipeline 
operations, compressor stations. (CGL aiming for <0.2% methane 
intensity, but still some leakage)
    *   **LNG Canada Facility:** Methane leakage during liquefaction.
*   **B. Transportation Emissions:**
    *   **Ship Transportation:** Burning of marine fuels (typically 
heavy fuel oil or LNG itself) for the ship voyage to China. This 
produces CO2.
*   **C. Combustion Emissions (in China):**
    *   **Regasification:** Converting LNG back into natural gas for 
distribution.  This process releases heat and a small amount of CO2.
    *   **Combustion for Heat:** Burning the natural gas to generate 
heat. This is the primary source of CO2 emissions in this scenario.
    *   **Potential for Combustion Inefficiency:**  If the burners are 
old or poorly maintained, combustion can be incomplete, releasing more 
methane.

**Scenario 2: Chinese Coal Mining**

*   **A. Coal Mining Emissions:**
    *   **Methane Release:** Significant methane emissions during coal 
mining operations (methane is trapped within coal seams). This is a 
major source of GHG emissions from coal mining.
    *   **Coal Processing & Transportation:**  Dust, methane release 
during coal processing and transportation.
*   **B. Combustion Emissions (in China):**
    *   **Combustion of Coal:** Burning coal to generate heat. This is 
the primary source of CO2 emissions. Coal combustion is generally more 
carbon-intensive than natural gas combustion.
    *   **Potential for Combustion Inefficiency:** Like natural gas, 
coal combustion can be inefficient, releasing unburned coal particles 
and other pollutants.

**Comparison of GHG Emissions**

Let's break down the comparison into key areas:

*   **Methane Emissions:**  Scenario 1 (Dawson Creek LNG) generally has 
*higher* methane emissions than Scenario 2 (Chinese Coal).  While coal 
mining releases methane, the capture and utilization of that methane is 
increasing.  The upstream losses in Scenario 1 (gas production, 
pipeline) are difficult to avoid completely.
*   **Carbon Dioxide Emissions:** Scenario 2 (Chinese Coal) *typically* 
results in *higher* CO2 emissions per unit of heat produced. Coal is 
more carbon-intensive than natural gas.  Even with efficiency 
improvements in the Dawson Creek LNG pathway, coal generally produces 
more CO2.
*   **Overall GHG Intensity:**  The overall GHG intensity (total GHG 
emissions per unit of heat) is a complex calculation.  It depends on 
various factors, including:
    *   Methane leakage rates in the Dawson Creek pathway.
    *   Efficiency of coal mining and combustion in China.
    *   Transportation distances.
    *   The specific type of coal being used.

**Overall Assessment:**

* **Historically, the coal pathway has likely been more GHG intensive 
overall.** Older coal plants, and older mining practices, tended to have 
higher methane leakage rates and lower energy efficiency.
* **The Dawson Creek LNG pathway is becoming increasingly competitive, 
but it’s still highly dependent on minimizing methane leakage.**  
Improved monitoring technologies, stricter regulations, and better 
operational practices are essential to reducing methane emissions in 
Scenario 1.  If methane leakage can be kept below 0.5% or lower, the LNG 
pathway could potentially be lower than Scenario 2.
* **Both scenarios present significant environmental challenges.** 
Reducing GHG emissions in both pathways requires ongoing efforts to 
improve efficiency, reduce leakage, and transition to cleaner energy 
sources.



**Important Considerations:**

*   **Well-to-Gate vs. Full Life Cycle:** This analysis focuses on 
"well-to-gate" (from extraction to combustion). A full life cycle 
assessment would include emissions from manufacturing equipment, 
infrastructure development, and decommissioning.
*   **Regional Variations:** Mining practices and energy efficiency vary 
significantly within China, impacting the GHG intensity of Scenario 2.
*   **Technological Advancements:** New technologies, such as carbon 
capture and storage, could further alter the GHG intensity of both 
scenarios.
