III. Escaping an Escher Print
Our continued embrace of natural gas congers images of an Escher print, a never-ending strange loop that optically obscures embedded anomalies. To avert a scenario where, in 2050, we have billions invested in natural gas infrastructure that becomes a stranded asset or continues to produce GHG emissions, we must assume—
- Natural gas remains essential for the modern electric grid and for home heating, at least for the next decade or so;
- Continued investment in natural gas infrastructure can be utilized to support the build-out of future robust hydrogen energy systems (for both producing and transporting hydrogen);
- Natural gas-powered electric generating stations will be coupled with CCUS technologies within a meaningfully significant time-frame; and
- Interim policies will be implemented swiftly enough to offset sufficiently the risk of meaningfully significant methane emissions.
Each assumption, unfortunately, contains a myriad of factors, leaving a wide margin of error. Before exploring a few critical ones, it is worth acknowledging that we must presume the political winds will remain calm enough to continue the present policies ushered in during the Biden Administration. Then, we must accept that regulatory programs will be fashioned to account for market changes.
Arguably, more significantly, we must agree that new natural gas infrastructure is indispensable for a reliable electric grid and national supply of heating capacity. Projections seemingly suggest it is. Our electricity needs will grow between now and 2050; and the transition to electric vehicles only intensifies the urgency of shoring up a reliable electric grid. Of course, even the EIA predicts that, by the early 2030s, the majority of natural gas produced in the United States will be exported either by pipeline or as LNG: it “will become larger than any domestic end-user sector, including residential, commercial, industrial, and electric generation.” Although we are the world’s largest consumer of natural gas and became a natural gas exporter in 2017 (and now the third largest exporter), as exports rose so, did production and a corresponding decrease in price, fueling additional consumption but not enough to offset the production increase. And at least as of spring 2022, a Pew research report suggests the majority of Americans do not oppose funneling natural gas to overseas markets.
This Essay cannot wade into the dialogue over whether renewable energy will be sufficient and, if so, when that might occur, but any assumption that natural gas will be essential for the electric grid for beyond another twenty years is problematic. Technological change occurs too rapidly to offer a sound prognosis for a future beyond, say, a decade. Projections about peak oil never materialized. High noon for natural gas faded into the sunset as horizontal drilling and hydraulic fracturing became economical. Even without the Clean Power Plan, utilities shuttered their coal-fired power plants faster than would have been necessary under the plan. Battery technologies could improve dramatically, for storing electricity on the grid (married to renewables) and for automobiles. Notably, the automobile industry champions a transition to electric vehicles likely quicker than when anyone expected a decade ago. Widespread adoption of small modular reactors could transform the electric grid, and electric heat pumps could eclipse natural gas heating, while new homes could enjoy induction ranges rather than gas burners. After all, today, many enjoy talking on their Apple Watch, while ten years ago, it would be three years before Apple’s Tim Cook would announce its arrival. A survey of senior business leaders in 2017 suggested that less than 20% were aware of artificial intelligence; and today, one would be quite ill-informed to have not heard of ChatGPT. Consequently, while perhaps we lack confidence to profess that natural gas will be unnecessary for another twenty years (or less), we should be equally cautious to pronounce it will remain indispensable.
One significant assumption involves examining how much our natural gas pipeline infrastructure will support future robust hydrogen systems. Currently, the meager miles of hydrogen-dominant pipelines are concentrated in the Gulf Coast, and worldwide “most hydrogen pipelines are owned by merchant hydrogen producers who sell their hydrogen to industry in bulk.” It seems somewhat trite to tout that new natural gas infrastructure should accommodate fuel switching, when nothing currently demands it. No consensus even exists on the applicable regulatory program for hydrogen pipelines and accompanying infrastructure—some suggest hydrogen pipelines should be regulated under the Interstate Commerce Act; others promote the NGA. And while FERC may employ the NGA when exploring tariffs that include other constituents flowing through a pipeline that could affect a line’s integrity, such as renewable natural gas (or biogas), using hydrogen as a justification for investing billions of dollars in new natural gas pipelines appears questionable. Some percentage of hydrogen and natural gas can safely be blended in existing natural gas pipelines and blending is not new, but just how much blending is possible remains uncertain—and the same is true for the accompanying compressors and equipment. A late 2022 report by the National Renewable Energy Laboratory encouraged that “additional research across the entire hydrogen and natural gas supply chain will be needed to fill current knowledge gaps and better inform [decisionmakers] on future blending projects.” And the Energy Department cautions that a blending percentage will “depend on the design and condition of current pipeline materials, of infrastructure equipment, and of applications that utilize natural gas.” In Europe, therefore, conversations focused on proposed new natural gas infrastructure include exploring its blending capabilities.
Sadly, this question and others escape meaningful inquiry here in the United States. This is despite that companies like Southern California Gas Co., one of the nation’s largest local gas distribution companies, is following an ASPIRE 2045 program for net zero emissions by 2045, highlighting hydrogen as a component—but principally green hydrogen from renewable energy. While, therefore, any examination seemingly should be encouraged when considering any new natural gas infrastructure, FERC’s program for considering new proposals abjures it. This is despite warnings in 2022 regarding how “FERC is under heightened pressure this year to reform the way it greenlights new pipelines, following recent court rulings and criticism that it has not done enough to analyze the environmental effects of natural gas infrastructure.”
FERC’s Abdication. FERC exudes a penchant for approving new natural gas infrastructure absent compelling reasons counseling otherwise. Indeed, the Commission’s approach toward reviewing natural gas projects has been plagued by various elemental concerns, most of which I chronicled earlier. The Commission clings to an outdated 1999 policy for addressing NGA certificate applications. When it attempted to update these policies that have since proven problematic, including the byzantine way the Commission and the pipeline companies employ NGA’s eminent domain authority, often to the detriment of landowners, the fierce backlash stalled the effort. Notably, however, three issues inform our present discussion. First, the Commission employs a rate of return for newly constructed interstate natural gas pipelines that affords a rate of return that is arguably too enticing from a short-term business perspective. This could favor capital investments in pipelines when the investment might appear profitable in the short-term, regardless of future regulatory initiatives that might shorten the economic life of a project—and possibly produce a stranded investment.
Second, FERC’s examination of whether a project is in the public interest and, as such, a need for the natural gas is anything but searching. FERC exhibits an affinity for approving a proposed natural gas infrastructure project, absent strong evidence questioning the merits of a particular project. In her analysis of FERC’s approval of 125 pipeline projects between 2014 and 2018, Romany Webb concluded that FERC generally avoids examining environmental issues in any depth—focusing more on economic analysis. Its 1999 Certificate Policy skews the deck: it emphasizes an economic test that balances the beneficial and adverse economic effects, and only when the former outweighs the latter will it proceed with an environmental analysis. And the economic analysis, as noted above, is often skewed because FERC merely relies on precedent agreements with little scrutiny unless forced. If existing customers are not being asked to subsidize a new project, no adverse effects would exist; if the project is a greenfield project, FERC similarly expresses little economic concern because it considers the risk of subsidization or degradation of existing customers unlikely. For instance, the D.C. Circuit chastised FERC for not examining the adequacy of the precedent agreements for the NEXUS Gas Transmission project that were designed, according to the City of Oberlin, Ohio, for exporting gas to Canada. FERC responded to the court’s remand by concluding that, regardless of the precedent agreements, shipping gas to Canada was in the public interest in accordance with its 1999 policy statement. Perhaps so, but the outcome seemed preordained. Not surprisingly, the Commission’s environmental analysis also occasionally appears slim upon review—ostensibly diminishing a project’s impact on the environment, aside from on the climate.
Finally, the Commission openly struggles with whether or how to examine GHG emissions associated with a proposed project. The Commission’s somewhat mercurial approach toward addressing GHG emissions associated with a project is possibly the most pronounced instance of where meaningful climate change policy is avoided. It became part of the floundering play by the Commission to update its 1999 Certificate Policy, only to cost its then-acting Chairman his job. FERC generally avoids examining upstream (indirect) effects of possibly inducing more natural gas development. And when it can, it relegates the importance of downstream GHG emission effects as well. During the 2023 summer, FERC Commissioner Allison Clements lamented how the Commission not only ought to revisit updating its Certificate Policy but should also comply with the requirement to consider and assess GHG emissions associated with a project approval. The D.C. Circuit soon thereafter suggested in an oral argument that perhaps the Commission ought to delay approving new projects until it updates its policy.
When the Commission considered the Henderson County Expansion Project, a roughly twenty-four-mile pipeline from Kentucky to Indiana, it refused to announce any judgment on whether the environmental analysis should have employed the social cost of carbon as a metric for assessing GHG emissions. When announcing the availability of the environmental impact statement (EIS), it noted how the document “is not characterizing the Project’s greenhouse gas emissions as significant or insignificant because the Commission is conducting a generic proceeding to determine whether and how the Commission will conduct significance determinations going forward.” During scoping for the project, the EPA expressed its concerns with the purpose of and need for the project, as well as its possible climate change impacts (including from methane leakage) and potential impact to wetlands. It later repeated aspects of these concerns when commenting on the final EIS. The Citizens Action Coalition of Indiana, however, requested rehearing of the Commission’s October 20, 2022 Order granting the necessary authorizations, specifically objecting to an allegedly deficient EIS. In a controversial move, the Commission denied rehearing in June 2023 without addressing the principal argument about analyzing GHG emissions. And the Commission’s spokesperson deflected criticism by observing how “[t]he Commission has made tremendous progress clearing the backlog of natural gas infrastructure projects needed for reliability” and Chairman Phillips “remains consistent and cooperative” in “mov[ing] orders forward.”
LNG: FERC and DOE. LNG export projects must wade through a labyrinth regulatory process that includes DOE as well as FERC, but the cards generally remain in their favor. For the most part, LNG export decisions by DOE are presumptively considered as in the public interest. After 1992, countries with a free trade agreement (FTA) with the United States “shall be deemed to be consistent with the public interest” and, as such, granted the authority to export “without modification or delay.” Similarly, the presumption also applies to “small-scale” natural gas exports to non-FTA countries. Then, for larger export projects in countries without an FTA, DOE conducts any relevant environmental inquiry and seemingly examines whether approving the export would serve the public interest. As of April 2023, DOE had existing authorizations under forty-one long-term orders for exporting 49.83 Bcf/d, excluding FTA and small-scale exports.
Recent DOE authorization orders suggest the department follows President Biden’s earlier commitment to promote LNG exports, primarily for Europe. And, analogously, Europe correspondingly has, for the first time, received more natural gas from LNG imports than from pipelines. The 2022 Environmental Integrity Project suggests that, as of that year, the DOE’s “role in the LNG permitting process is largely one of a rubber stamp.” In 2022, for instance, DOE expanded the volume authorized for export from two Gulf Coast terminals. And in DOE’s listing of its 178 orders in 2022, it appears the department generally accepts the industry’s requests. The Administration’s support for an LNG project in Alaska further illustrates its cautious approach toward chilling any LNG investment. When, moreover, the D.C. Circuit upheld the $39 billion Alaska LNG project, the FERC Chairman observed how it reflected “the fact [that] we’re moving in the right direction” for energy policy.
To be sure, DOE seemingly strengthened its approval policy by announcing how a company will have only up to seven years from an order granting the authorization to commence construction (or, before ninety days prior to the seven-year expiration period, apply for an extension). The industry perceived this as tightening standards surrounding LNG approvals. Yet, as DOE explained, this policy reflects LNG orders since 2011, and most of what DOE is concerned with is allowing companies to stretch out too long by continuing to seek extensions (sometimes at the last minute) when they commence construction. This appears unlikely to chill LNG proposals.
Conclusion
How the United States confronts the natural gas gambit is quintessentially a role for energy experts capable of canvassing the panoply of factors informing how at least the United States can reach net zero by 2050. Whether that means continuing FERC’s approach toward considering new or modified interstate natural gas projects or DOE’s presumption toward approving LNG export projects remains a complicated matter. Perhaps too, at least for now, natural gas is fundamental to stabilizing the electric grid, and there is little we should do. After all, EIA projects that even if a natural gas moratorium were imposed in 2024, it would merely reduce CO2 emissions from all sectors by a paltry 1% by 2050. And whether natural gas infrastructure ought to remain tethered to the burgeoning hydrogen-centric energy push is a query still in its infancy. Answering it, in part, naturally requires addressing whether existing and future efforts will target green or blue hydrogen. The former might diminish the role of existing natural gas infrastructure, consequently. But that, of course, could, in turn, be tempered by how the Internal Revenue Service deploys the 45V tax credit and whether that credit will be available for marrying other renewable resources, such as small modular reactors, with hydrogen or whether the credit (for purposes of “additionality”) will favor marrying hydrogen to natural gas.
No crystal ball can project regulatory changes, technological advances, and market changes that could steer us along the foremost path forward. Instead, we must develop institutional procedural mechanisms sufficiently comprehensive and flexible enough to monitor trends and, correspondingly, render efficacious decisions from gathered information. Our existing regulatory structure arguably does the opposite. Each participant, whether state or local entities, FERC or some other federal agency, contributes in some measure to energy choices, but their regulatory or other charge narrows their focus to what is before them. Each year EIA may project twenty-five years into the future, but transformations occur rapidly, and little about EIA’s efforts impact the choices made by the energy-related actors, such as FERC. To confront all facets of climate change, particularly the prospects for natural gas and how to eliminate methane emissions, that must change.
We should construct appropriate institutional mechanisms capable of asking the right questions. This suggests state regulatory commissions and FERC ought to appreciate how their decisions today can solidify possibly problematic natural gas infrastructure long after the immediate need for natural gas has faded. To avert this scenario, they should be capable of probing whether any proposal involving natural gas is absolutely necessary, not only today or the following year but five or more years hence as well. Regional entities could be formed to aid the endeavor; and those entities should be tasked with combining EIA’s analyses with similar regional assessments and projections on the need for natural gas not just immediately but for the entire physical and economic life of the infrastructure. This ought to include requiring any proposal for new natural gas infrastructure to accept a decommissioning or transition plan. FERC, for instance, should demand from applicants an enforceable timeline for achieving zero emissions: when will the project proponent commit to CCUS, agree to transition away from natural gas and toward hydrogen, or otherwise agree to shutter the infrastructure? A commitment, in short.
Climate change is propelling us into a perilous future, and yet we continue to promote natural gas with unverified assumptions about how we can arrest methane emissions. Those assumptions may well prove our prescience. Natural gas may well provide a catalyst capable of transitioning our energy systems toward a much more dominant hydrogen-based economy. But a gambit with natural gas is risky. Our future, consequently, warrants being cautious and charging our institutions with the obligation to prevent natural gas from becoming a proverbial sword of Damocles preventing our transition to a zero-carbon economy sooner rather than later.
