A report from the Center for Biological Diversity demonstrates what many of us have feared—that carbon emissions from Biden-approved fossil fuel projects will cancel out the expected CO2 reductions from the Inflation Reduction Act.

“Approving more fossil fuels not only torches our climate future, but it also harms people’s health, degrades ecosystems, and threatens wildlife,” writes Shaye Wolf, the lead author. “The potential carbon emissions from 17 massive fossil fuel projects approved by the Biden administration are larger than the projected emissions reductions from the IRA and other climate policies.”

Those 17 projects have the potential to release emissions totaling 1,642 million metric tons of CO2 equivalent per year, or the same as the annual emissions of 440 coal-fired power plants.

We represent heavily polluted communities throughout the State of California. Our communities border oil refineries, gas-fired power plants, industrial farming operations, fossil fuel extraction facilities, waste processing centers, ports, transportation corridors and other polluting operations. These cumulative sources of pollution cause a wide range of adverse health outcomes in working class communities of color. Our communities share a common fence with facilities and operations that emit toxins, foul smells, and noise and cause nuisance impacting people’s quality of life at all hours of the day and night.

The State of California intends to expand the use of hydrogen as a fuel, and to this end, we offer these guiding principles, which are essential to respect and protect our communities.

The following principles represent our collective values and positions to support communities as hydrogen energy is utilized across the state.

These principles were developed in 10 workshops and learning sessions for environmental justice partners across California between March and September of 2023. The learning sessions examined the current science, including risks, benefits, and unknowns, and shed light on each stage of the hydrogen cycle, including production, delivery, storage, and use. The workshops allowed our organizations to discuss different perspectives, build consensus, and reflect on how hydrogen may impact our communities. 

We adamantly oppose all non-green hydrogen proposals and projects. We insist that new projects protect communities first and do not perpetuate the injustices that polluting infrastructures impose on fence-line communities today. Each stage of the hydrogen life cycle—production, delivery, storage, and end use—can present unique risks and harms to environmental justice communities and to all Californians.

Discussions about building new green hydrogen infrastructure must involve the community, and its members should be meaningfully engaged. Siting green hydrogen infrastructure should also take into account the cumulative impacts of environmental justice communities and the risks associated with hydrogen.

In agreeing to be interviewed by the Spectator under the title the folly of Net Zero GMB General Secretary Gary Smith lets his members down; not least because remarks like these from a leading trade unionist help give Rishi Sunak encouragement to accelerate his retreat from the government’s already inadequate climate targets.

The phrase “the folly of Net Zero” makes as much sense as “the folly of getting into the lifeboats when the ship is sinking”. 

Difficulties in making a transition to sustainability does not mean that making it isn’t essential, and the faster we move the less damage is done. We can see that damage all around us even now. 

Gary doesn’t seem to get this, any more than Rishi Sunak does, and he latches on to some of the same lines as the PM does, albeit with a more pungent turn of phrase. To go through these point by point, quotes are either directly from Gary Smith or the Spectator.

Blue hydrogen hype has spread across the U.S., spurred by the billions of dollars of government funding and incentives included in the 2021 Bipartisan Infrastructure Law (BIL) and the 2022 Inflation Reduction Act (IRA). The fossil fuel industry promises that blue hydrogen, produced from methane or coal, can be manufactured cleanly and contribute to climate change mitigation measures. As we demonstrate in this report, the reality is that blue hydrogen is neither clean nor low-carbon. In addition, pursuing it will waste substantial time that is in short supply and money that could be more wisely spent on other, more effective investments for reducing greenhouse gas emissions in the immediate future.

In short, fossil fuel-based “blue” hydrogen is a bad idea.

Blue hydrogen’s environmental benefits rest largely on the assumptions baked into a Department of Energy (DOE) model named GREET (Greenhouse Gases, Regulated Emissions and Energy use in Transportation) that is the congressionally mandated evaluation tool for U.S. hydrogen projects. Due to a set of unrealistic and flawed assumptions, the model significantly understates the likely greenhouse gas intensity associated with blue hydrogen production.

Among the key shortcomings:

• It assumes an upstream methane emission rate of just 1%. This is far less than recent peer-reviewed scientific analyses have found and what has been demonstrated by numerous airplane and satellite surveys.
• It uses a 100-year Global Warming Potential (GWP). This significantly understates methane’s environmental impact in the short term, since its 20-year GWP is more than 80 times that of carbon dioxide (CO2).
• It does not include any estimate (either over 20 or 100 years) for the global warming impact of hydrogen, which works to extend the lifetime of methane and increase its atmospheric abundance. Hydrogen also has a 20-year GWP more than 30 times that of CO2.
• It does not include a full life cycle analysis (LCA) of all the emissions from the blue hydrogen production process. In particular, downstream emissions from the produced hydrogen and the generation of the electricity needed to compress, store and transport the hydrogen to the ultimate user(s) are excluded.
• It includes overly optimistic assumptions about the effectiveness of carbon capture processes.

Using more realistic numbers shows blue hydrogen to be a dirty alternative. For example, if we change just two variables—using methane’s 20-year GWP and a more realistic 2.5% methane emission rate—the carbon intensity of blue hydrogen calculated by GREET jumps to between 10.5 and 11.4 kilograms of CO2e/kgH2 (kilograms of carbon dioxide equivalents emitted per kilogram of hydrogen). This is between two and three times the 4.0 kg CO2e/kg hydrogen Clean Hydrogen Production Standard (CHPS) established by Congress and the DOE. Note that these already very high carbon intensity figures still reflect DOE’s overly optimistic assumption that hydrogen production facilities will capture at least 94.5% of the CO2 they produce. They also exclude the impact of downstream hydrogen emissions.

If more conservative assumptions are used, reflecting: 1) more realistic carbon capture rates; 2) downstream leakage of the hydrogen produced; and 3) downstream CO2e emissions from the production of the electricity needed to fully compress, store and transport the hydrogen to the site where it will be used, then blue hydrogen gets even dirtier, with a carbon intensity more than three times as much as the DOE’s clean hydrogen standard.

Given these results, IEEFA is extremely concerned that the current blue hydrogen hype is going to result in the funding of projects that exacerbate climate change and lock in our reliance on fossil fuels for decades. For this reason, we have undertaken a series of analyses into the emissions from blue hydrogen production based on current scientific knowledge of methane emissions and hydrogen leakage rates and the existing status of carbon capture and sequestration (CCS) technologies. This report focuses on the production of blue hydrogen from methane; a subsequent report will examine hydrogen from coal gasification.

To have a chance of limiting global heating to 1.5 degrees, there must be no new oil and gas production. But fossil fuel industries have other ideas, aggressively promoting themselves as ‘green’, to ensure that extraction (and their mega-profits) continue.

Instead of focusing on proven solutions to cut emissions – renewables and energy efficiency – massive public subsidy is being diverted to develop carbon capture and storage (CCS), and related technologies: 'blue' hydrogen and burning biomass.

Here in the UK, £20 billion funding has just been announced for CCS. Two pilot industrial clusters are already being driven forward, on the East Coast (Humber/Teesside) and Hynet (Liverpool Bay/North Wales).

Carbon capture may prove necessary in a few industries, but industrial and energy policy is being dangerously distorted by the fossil fuel industry’s interest in prolonging the use of oil and gas whilst developing a lucrative new revenue stream in so-called 'carbon management'.
