The document argues that the DOE's proposed 4 kgCO2e/kgH2 standard is too weak and should be lowered to 1 kgCO2e/kgH2 to prioritize truly zero-emission hydrogen. It criticizes the GREET model for underestimating methane leakage and grid emissions, warns against the safety and environmental risks of carbon capture and storage (CCS), and demands that the hydrogen hub program incorporate strict environmental justice protections and community engagement.

The report analyzes the impact of three US federal tax subsidies—the expensing of intangible drilling costs (IDC), percentage depletion, and accelerated amortization of geological and geophysical (G&G) expenses—on the profitability of oil and gas projects from 1998 to 2019. Using a financial model of 2,450 fields, the authors find that these subsidies increased the expected net present value of projects by billions of dollars annually, often exceeding $20 billion in high-price years. The benefits were heavily concentrated in unconventional shale developments in regions such as the Permian Basin and Appalachia, and disproportionately benefited independent firms over integrated ones. While subsidies provided 'super normal' profits during high-price periods (2007-2014) without significantly altering drilling decisions, they were critical for the viability of marginal projects during price drops, such as in 2016 for oil and 2010-2012 for gas in Appalachia.

The report identifies and assesses nine technologies to reduce the flaring of associated gas in US tight oil fields, concluding that Natural Gas Liquid (NGL) recovery, Compressed Natural Gas (CNG) trucking, and Gas-to-Power (for local loads) are the most mature and scalable options. It highlights that flaring in the Bakken and Eagle Ford basins reached approximately 125 billion cubic feet per year by 2013. The analysis emphasizes that while technical solutions exist, robust regulations are necessary to eliminate routine flaring. A case study on Alaska's Shublik formation suggests that while the region has high potential, its remoteness and harsh climate necessitate early infrastructure planning to avoid future flaring.

The document evaluates technical and commercial viability for several associated gas utilization technologies in US tight oil fields. It identifies gas gathering, CNG trucking, NGL recovery, gas-to-power, and Mini-GTL MT as technologies that pass initial screening, while gas reinjection, Mini-LNG, Mini-GTL FT, and ammonia production are rejected due to scale, maturity, or economic constraints. The report provides detailed technical specifications, cost models, and case studies for these options, specifically focusing on the Bakken region of North Dakota.

Earthjustice and a coalition of nonprofit organizations petition the EPA to regulate oil and gas wells as area sources, arguing that the rapid expansion of drilling—particularly via hydraulic fracturing—in metropolitan areas poses a non-negligible risk to public health. The document details the emission of toxic air pollutants such as benzene and formaldehyde, highlights the vulnerability of children and overburdened communities, and identifies significant regulatory gaps in existing EPA rules. It concludes that available technologies, such as green completions and vapor recovery units, can substantially reduce these emissions.

The document assesses the environmental and economic impacts of flaring associated gas in the Bakken and Eagle Ford formations, concluding that routine flaring is unnecessary due to the availability of mature alternatives like CNG trucking, NGL recovery, and gas-to-power generation. It argues that current regulations, such as those in North Dakota, are inadequate and calls for robust nationwide standards from the BLM and EPA to mandate gas capture.
