CPD: The long-term prospects of natural gas and midstream assets


What are the long-term prospects for natural gas and midstream infrastructure assets as an investment opportunity?

While the speed of ultimate decarbonisation remains unclear, there appears to be a real opportunity for multi-decade investment as every country moves towards a cleaner environment.

In this article, Peter Aquilina (Senior Investment Analyst and Head of ESG) analyses what the global Net Zero goal means for natural gas demand in the long term; and discusses how 4D analyses and values oil/gas midstream assets, considering both the risk and opportunity as we move towards Net Zero.

1. Paris Agreement commitments

The headline goal of the Paris Agreement is to limit global temperature increases to well below 2°C, preferably to 1.5°C, compared to pre-industrial levels. To achieve this goal, parties to the Agreement aim to reach global peaking of greenhouse gas (GHGs) emissions as soon as possible, so as to achieve a balance between anthropogenic emissions by sources and removals by sinks of GHGs[1] in the second half of the century. Broadly speaking, signatories to the Paris Agreement are looking for Net Zero emissions by 2050.

As of November 2021, 193 states and the European Union are parties to the Paris Agreement (a further four countries are signatories, but are yet to ratify the agreement). These parties to the Paris Agreement cover approximately 98% of the world’s human-made emissions – a depiction is shown below.

Many countries outlined their current Net Zero plans at the recent UN Climate Change Conference (UNCCC) in Glasgow (GOP26) in late 2021. Within these plans, most countries also outlined interim decarbonisation commitments for 2030. These interim targets are intended to provide a more tangible medium-term target for countries to establish detailed plans and to indicate the pace of GHG emissions reduction.

Albeit the pace of decarbonisation between now and 2050 is still unclear, there seems to be widespread political support to achieve Net Zero. This will no doubt create a strong push to decarbonise economies globally, providing opportunities and risks for investors, especially for certain infrastructure sub sectors, such as midstream oil/gas.

The rest of this article looks at how 4D balances this opportunity with risk for this sector in particular.

2. Balancing conflicting challenges

With roughly 25% of all global emissions coming from electricity generation alone, it’s clear the energy sector is central to achieving a Net Zero goal. However, this goal cannot be viewed in isolation, and energy market participants must balance carbon reduction strategies with other social obligations.

In summary, we believe there are three main targeted outcomes for energy market participants as they seek balance between energy transition, political goals, and customer satisfaction:

  1. Power needs to be affordable to customers.
  2. The delivery of power needs to be reliable and consistent.
  3. GHG emissions need to be removed or offset in the shortest time possible.

An additional consideration is to support economic growth, predominantly through employment and investment. The balancing of these factors may vary depending on the perspective of the individual or government. However, these three (or four) targets are typically prescribed by all energy market participants and stakeholders.

3. Benefits of natural gas to energy markets

Natural gas has inherent qualities which support the above targets of affordability, reliability and GHG reduction.

  • Versatility: natural gas power generators can technically be turned on and off quickly as compared to other baseload power sources such as nuclear and coal. This makes peaking gas generators a strong compliment to support renewable power generation and ensure ongoing security of supply.
  • Storable: natural gas can be stored in underground salt caverns in large volumes for long periods of time, which also makes it a strong complement for renewables.
  • Transportable: natural gas can be transported within existing pipeline infrastructure, or can be converted into liquid by cooling to -162 degrees Celsius and transported by ship/rail, even internationally.
  • Plentiful: natural gas is relatively plentiful and available in many geographic locations, with the International Energy Agency (IEA) estimating that there are enough recoverable resources to last around 230 years.
  • Affordable: according to Lazard investment[2] bank research, the most efficient gas fuelled power generator has an all-in cost (as measured by Least Cost of Energy (LCOE)) of between US$44 – US$73 / MWh, which is the lowest of fossil fuels (coal generation between US$65 – US$159 / MWh);
  • Cleaner: burning natural gas results in fewer emissions of nearly all types of air pollutants than burning other fossil fuels. Natural gas generation releases about 117 pounds of CO2 million British thermal units (MMBtu) equivalent compared with more than 200 pounds of CO2 per MMBtu for coal, and more than 160 pounds per MMBtu for distillate fuel oil[3].

The above attributes make natural gas an important transitory energy fuel in maintaining reliability and affordability for customers as the world transitions away from GHGs. It is on this basis that we expect to see significant ongoing global demand for natural gas and the assets that transport it.

4. Long-term prospects for natural gas

Forecasts of the pace of GHG emissions reduction, and demand for natural gas in the long term, can be fraught with error and/or bias. A number of stakeholder groups have commissioned their own studies and forecasts from various consultants, which may cynically have a pre-determined goal that needs to be supported by the analysis. It is impossible to determine which, if any, forecast will be correct, and it is often difficult to understand if any particular forecast has inherent bias assumed within it.

Based on the views and forecasts of independent industry agencies and energy consultants, we are confident that natural gas will have a role to play in the energy mix in the very long term. Based on our review of a number of forecasts and studies, we are of the view that:

  • Achieving Net Zero emissions AND maintaining global temperature increases to 1.5°C by 2050 is becoming optimistic, if not unrealistic, due to the limited progress in setting and/or achieving national short/medium-term decarbonisation targets.
  • There could be some decline in natural gas demand by 2050, although the magnitude varies widely between decarbonisation forecasts. A more aggressive, yet reputable Net Zero scenario developed by the International Energy Agency (IEA) implies a 39% reduction in volume demand compared to 2020, while others assume very little demand erosion.
  • There is unlikely to be a significant reduction in natural gas demand by 2030.

5.  What does this mean for the long-term prospects of the midstream sector?

At 4D Infrastructure, we define the ‘midstream’ sector as the infrastructure used in the transportation, storage, extraction and refining of natural gas, natural gas liquids (NGLs) and crude oil. Midstream is the ‘glue’ between upstream E&P and downstream distribution.

With the transportation of oil and gas remaining the core business of midstream companies for the reasons discussed above, we see a longer ongoing demand profile for those transporting gas. However, there are also potential future opportunities for companies to re-use (and re-purpose) their assets and expertise in a Net Zero world. The expertise of midstream management teams in managing energy infrastructure is easily transferable to no/low carbon fuels. In addition, the prominent position of terminals in industrial hubs and pipeline assets in connecting demand centres provides a good basis for utilisation for low/no carbon fuels such as hydrogen, CO2 from CCUS, renewable natural gas (RNG), and other biofuels.

Taking all of the above into consideration, we believe the core business for the midstream sector in transporting oil/gas is almost certain to be maintained through the period to 2030. Further to that, even assuming aggressive decarbonisation scenarios, there is still likely to be utilisation of select midstream assets in 2050 and beyond. Beyond this, there is the opportunity for companies to reposition their business and re-use their assets and skills for low/no carbon fuels. Midstream assets connected to oil/gas basins with economic and geographic competitive advantages, and to demand centres (domestic and international), are likely to be heavily utilised in the long term. This doesn’t consider the potential for assets to be repurposed to carry low/no carbon fuels such as hydrogen, CO2 from CCUS, renewable natural gas (RNG) and other sustainable biofuels.

6. Investing in midstream gas assets

We believe that midstream companies satisfy our definition of infrastructure, although their specific characteristics could put them more at risk of being stranded in the very long term (>2050) under some aggressive Net Zero scenarios. However, even under aggressive decarbonisation scenarios, midstream companies with strategically placed assets connecting the lowest breakeven cost, natural gas basins are likely to be heavily utilised in 2050 and beyond.

Some of the due diligence and valuation considerations we adopt in selecting the best midstream names in the sector and valuing them appropriately include:

  • Adopting a base case in valuation models assuming that Net Zero is achieved to some degree by 2050: global temperature growth is maintained at or below 2°C.
  • Strong preference for midstream companies that operate in natural gas directed basins: natural gas is often a by-product of exploration & production (E&P) companies drilling for crude oil. The decision around continued production is based on the economic value of crude, so this production is often cut when the economics for crude production are not satisfied.
  • Adopt conservative assumptions: only incorporate growth assumptions for contractual price uplifts and associated with development projects that have been secured by management. Do not include any market growth associated with long-term forecasts.
  • Not valuing ‘blue sky’ opportunities: opportunities for midstream companies to re-purpose assets for utilisation with low/no carbon fuels is only in its infancy, and although a great opportunity, it is not currently being significantly valued in our models.
  • Conservative terminal value assumptions: acknowledging the uncertainty for growth associated with any fossil fuels beyond 2050, and its impact on earnings of midstream assets, we adopt conservative terminal value assumptions.
  • Scenario analysis: run scenario analysis within models to determine the impact on valuations under a number of different decarbonisation trajectories.
  • Due diligence for competitive advantages: develop a strong understanding of the competitive advantages of the various gas supply basins and which are likely to continue to be economic for E&P producers in a potential low demand, low price environment. This provides confidence in utilisation post 2030, as gas prices potentially decline in line with reduced demand. Alternatively, we look to understand which arterial pipelines are likely to be utilised in connecting demand centres and export terminals in the long term. Interconnection of assets from the wellhead to demand centres and export terminals ensures utilisation throughout the value chain.
  • Quality assessment: we undertake a detailed quality assessment, which incorporates an assessment of the quality and competitive advantages of company assets (point above), but also contractual defensiveness, ability to transition the business model into low/no carbon fuels, management quality, and financing position. This all provides insight into the sustainability of the business model.

7. Conclusion

There is significant uncertainty as to whether the globe will be able to maintain global temperature increases to ‘well below’ 2°C in line with the Paris Agreement. Despite the communicated target of most countries, the challenges to achieving this goal are great.

Irrespective of the world’s long-term carbon trajectory, most industry forecasts assume that natural gas has a role to play in the long-term global energy mix. Even assuming aggressive GHG reductions are achieved, and the globe is able to maintain temperature increases to below 2°C, natural gas volumes are still expected to be significant in the longer term. This is because 1) developing nations will still likely utilise natural gas after 2050 for energy production, and 2) natural gas will be used in combination with CCUS, carbon sinks and in the creation of blue hydrogen. Therefore, based on the continued demand for natural gas, the business model of midstream infrastructure names focused on processing and transporting natural gas is likely to be maintained. There is further potential upside from repurposing midstream assets for use with hydrogen, CCUS, RNG, biofuels and other renewable fuels, which many companies are starting to explore.

We at 4D adopt a cautious approach to investing in midstream oil/gas companies. We undertake significant due diligence regarding the quality of companies and their competitive advantages in the processing and delivery of natural gas. We also adopt conservative base case assumptions with regard to growth and terminal values, and undertake scenario analysis to understand the breadth of potential valuation outcomes. They also must adhere to strict ESG standards and stack up against their infrastructure peers on an overall quality basis. In doing this, we believe the investment proposition of specific midstream names is attractive.
