The Hydrogen Color Wheel: A Primer

Frederick M. Lowther ●

The international dialogue about climate change and the “net zero” world now includes a focus on hydrogen as an abundant source of energy useful in myriad ways (refining, fertilizer production, motive power, etc.) with potentially zero climate-harmful emissions. For those of us who took Chemistry 101 in high school, we know that hydrogen is by far the most abundant element in the Universe, representing an estimated 70 to 75 percent of all known matter. While that is an awesome number (giving rise to the common student question “How do we know that?”), the fact is that, here on Earth, hydrogen does not exist as a “free” gas—it is present here only in combination with other elements, notably oxygen, carbon, and nitrogen. Thus, to capture hydrogen for use in multiple applications, it must be separated from the paired substances (most commonly water (H2O) and natural gas (CH4)).

In the discourse around capturing hydrogen as a free gas, a color-coding terminology has emerged that rivals a paint store. I call it the “hydrogen color wheel” and it is the source of much confusion. While each of the color “codes” involves a somewhat detailed explanation, my goal in this post is to keep the detail short and within understandable limits.

A leader in stringent auto emission regulations, the State of California recently took additional steps in its effort to further protect the environment. On August 25, 2022, the California Air Resources Board (“CARB”) voted to require all new cars and light trucks sold in the state to be “zero-emission” by 2035.[1] The plan, officially known as the CARB Advanced Clean Cars II rule, was originally introduced via executive order by Gov. Gavin Newsom nearly two years ago.[2]

The plan mandates that “[i]t shall be a goal of the State that 100 percent of in-state sales of new passenger cars and trucks will be zero-emission by 2035. It shall be a further goal of the State that 100 percent of medium- and heavy-duty vehicles in the State be zero-emission by 2045 for all operations where feasible and by 2035 for drayage trucks. It shall be further a goal of the State to transition to 100 percent zero-emission off-road vehicles and equipment by 2035 where feasible.”[3]

Supreme Court Limits EPA’s Authority under the Clean Air Act

After seven years, three presidential administrations, and two appearances before the Supreme Court, the Obama Administration’s “Clean Power Plan” (“CPP”)—a Clean Air Act regulation designed to limit carbon emissions from existing coal-fired power plants (and later revised by the Trump-era “Affordable Clean Energy” (“ACE”) rule)—was struck down by the Supreme Court on June 30, 2022. See West Virginia et al. v. Environmental Protection Agency et al., No. 20-1530.

Relying on Section 111(d) of the Clean Air Act (“CAA”), the Environmental Protection Agency’s (“EPA’s”) CPP set a carbon emission limit that was essentially unattainable for existing coal-fired power plants. Consequently, EPA determined that the “best system of emission reduction” for carbon from these plants was to cause a “generation shift” from higher carbon emitting coal-fired sources to lower-emitting sources, such as natural gas plants or wind or solar energy facilities. Compliance with the CPP would have required a plant operator to: (1) reduce the amount of electricity the plant generated to reduce the plant’s carbon emissions; (2) build a new natural gas plant, wind farm, or solar installation, or invest in someone else’s existing facility and increase generation there; or (3) purchase emission allowances as part of a cap-and-trade regime. See West Virginia at 8.

EPA Reverses Course with the Mercury and Air Toxics Regulations for Power Plants

Margaret Anne Hill, Frank L. Tamulonis III, and Stephen C. Zumbrun

The saga for regulating mercury and air toxics from coal- and oil-fired power plants continues with a final rule promulgated by the U.S. Environmental Protection Agency (“EPA”) on April 16, 2020. EPA initially determined that it was “appropriate and necessary” under Section 112 of the Clean Air Act to regulate hazardous air pollutants (“HAPs”)—including mercury—for these types of power plants, commonly referred to as electric utility steam generating units (“EGUs”).[1] In a change of policy, EPA has now decided that the “appropriate and necessary” determination to regulate HAPs for these power plants—after two decades of additional EPA rules, and corresponding litigation—is no longer correct.[2]

A significant part of the backstory here is related to the U.S. Supreme Court’s decision in 2015 in Michigan v. EPA.[3] Briefly, the Court held that the EPA needed to consider costs in evaluating whether it was “appropriate and necessary” to regulate HAP emissions from coal- and oil-fired EGUs, especially the costs associated with compliance. Following the Supreme Court’s decision, EPA, under the Obama Administration, conducted a study in 2016 to evaluate these costs and concluded that it was still “appropriate and necessary” to regulate HAPs emitted from these sources.[4] The Trump Administration has now reversed course in issuing the April 16 final rule, effectively concluding that the EPA’s decision in 2016 was wrong.

Pennsylvania Plans to Join the RGGI CO2 Cap-and-Trade Program

At the outset of 2019, Pennsylvania Governor Tom Wolf set a goal for Pennsylvania to significantly reduce greenhouse gas emissions. Now, Governor Wolf plans to achieve that goal by taking the bold step to establish a carbon dioxide cap-and-trade program through executive action. On October 3, 2019, Governor Wolf issued an Executive Order directing the Pennsylvania Department of Environmental Protection (“DEP”) to begin the process for Pennsylvania to join the Regional Greenhouse Gas Initiative (“RGGI”, pronounced “Reggie”). RGGI is a market-based cap-and-trade program implemented by several Northeast states to reduce power sector CO2 emissions. Governor Wolf’s Executive Order made national headlines because of the potential implications of Pennsylvania—a state known for its coal and natural gas reserves—joining RGGI. But this news is only the start of a long regulatory process, one that could realistically take years to become implemented. At this stage, Pennsylvania fossil-fuel power generators should familiarize themselves with RGGI’s requirements and procedures as well as the rulemaking process by which the Commonwealth might join RGGI.

The RGGI Program

RGGI is a collective effort by its member states to create a Northeast regional cap-and-trade program affecting fossil-fuel power plants greater than 25 megawatts. Member states—currently Connecticut, Delaware, Maine, Maryland, Massachusetts, New Hampshire, New York, Rhode Island, and Vermont, with New Jersey in the process of rejoining—each enact statutory or regulatory programs in their respective states that are RGGI compliant. CO2 emitting power plants then participate in RGGI regional auctions to purchase CO2 emission allowances for usage, or to sell on secondary markets. RGGI caps the total amount of CO2 emission allowances, measured in tons of carbon, with the most recent cap being 80.2 MM-tons. Beginning in 2021, the cap will be set at 75.1 MM-tons, which will then be reduced by 30 percent between 2020 and 2030. Proceeds from the auctions are distributed to the respective states for investment in programs to further reduce CO2 emissions, such as energy efficiency, renewable energy, or consumer benefit programs.

Charting Climate Change Cases: A Survey of Recent Litigation

Margaret Anne Hill and Stephen C. Zumbrun

Introduction

Right now, cases involving climate change are being heavily litigated in courts across the United States. Hundreds of climate change-related cases have been filed in both federal and state courts, where parties are challenging governments’ and industry’s knowledge of and contribution to climate change. In the abstract, one would think that litigation involving emissions of greenhouse gases (“GHG”) linked to climate change would largely focus on the federal Clean Air Act. Yet, climate change-related cases now involve ever-expanding causes of action, including not only claims under the federal Clean Air Act and other federal statutes, but claims under the U.S. Constitution, state law claims, and common law claims.

There are several active cases that may have major implications on the government’s role in determining the direction of climate change policy, and on private companies’ past and future liability for alleged contributions to climate change, as well as knowledge of climate change impacts on business decision-making. This article discusses notable current cases involving climate change. Continue reading “Charting Climate Change Cases: A Survey of Recent Litigation”

Pipeline Update: Here Today, Gone Tomorrow? FERC’s Natural Gas Pipeline Greenhouse Gas Analysis Policy

Stephen C. Zumbrun

The Republican majority of the Federal Energy Regulatory Commission (“FERC” or “Commission”) has drawn a clear distinction with how and when the Commission will analyze upstream and downstream greenhouse gas (“GHG”) emissions when reviewing natural gas pipeline projects. But with the recent announced resignation by Republican Commissioner Robert Powelson, a pending Notice of Inquiry issued by the Commission, a separate advanced Notice of Proposed Rulemaking issued by the Council on Environmental Quality (“CEQ”), and a recent petition to the D.C. Circuit Court, this current established protocol may not last and by this time next year we may see a whole new approach to pipeline GHG analysis coming out of FERC.

United States Court of Appeals for the District of Columbia Circuit Vacates EPA’s Stay of Compliance Deadlines of Methane Rule

Amy L. Barrette

On July 3, 2017, in a 2-1 opinion, the United States Court of Appeals for the District of Colombia Circuit granted a petition by several environmental organizations that sought to vacate the Environmental Protection Agency’s (“EPA”) decision to stay the methane rule. In vacating the EPA’s stay, the Court concluded that the EPA lacked authority under the Clean Air Act (“CAA”) to stay the rule. Continue reading “United States Court of Appeals for the District of Columbia Circuit Vacates EPA’s Stay of Compliance Deadlines of Methane Rule”
