Generous tax subsidies for sustainable aviation fuels in the U.S.? Yes, but details matter

Aircraft jet landing

One of the Inflation Reduction Act’s key provisions is a powerful tax credit to spark the development and adoption of clean, low-carbon aviation fuels. Climate pollution from aircraft is often overlooked, but if aviation were a country, it would be among the top 10 greenhouse gas emitters.

The Biden administration is about to make a crucial decision on which fuels should be eligible for the tax credits. Getting this right is critical to whether this government subsidy will be money well spent.

Known Unknown: Current hydrogen leak estimates vary by up to 100-fold. We need to know more before betting the farm

Enthusiasm for hydrogen as a climate-friendly fuel of the future is everywhere. Hundreds of hydrogen energy projects worth more than $500 billion have been announced, and The International Energy Agency says hydrogen demand could increase sixfold by 2050.

Scientists, though, are confident that this leak-prone gas can warm the climate when it escapes into the atmosphere. Just how much warming will depend on how much hydrogen is emitted, and that remains a giant question mark. That’s why Environmental Defense Fund set out to identify the climate risks of future hydrogen emissions and help develop technology that can detect how much hydrogen escapes from today’s infrastructure.

EDF’s groundbreaking 2022 study explained how unchecked hydrogen emissions can severely undercut the climate benefit of switching from fossil fuels to hydrogen. We found that if it’s not done right, using hydrogen could be worse for the near-term climate than the fossil fuels it would replace.

New bipartisan legislation would give U.S. orphan well management efforts a huge boost

Senator John Hickenlooper (D-CO) meets with oil industry and environmental group leaders at kick-off event for orphan well remediation program in Adams County, CO

By Adam Peltz and Meg Coleman

Across the country, a million or more orphaned oil and gas wells threaten the climate, public health, groundwater and surface waters and hamper local economic development. Help is on the way thanks to a major federal effort to invest $4.7 billion in closing orphan wells under the Revive Economic Growth and Reclaim Orphaned Wells Act as part of the Bipartisan Infrastructure Law, but the scale of the problem is vast.

In order to get a handle on these orphaned wells, New Mexico Sen. Ben Ray Luján , Democrat,  and North Dakota Sen. Kevin Cramer, Republican,  worked together to secure well closure funding in BIL. Now, they have reintroduced the Abandoned Well Remediation Research and Development Act and a bipartisan group in the House led by Pennsylvania Rep. Summer Lee, Democrat,  and republican Oklahoma Rep. Stephanie Bice  have introduced a companion bill. This important, bipartisan legislation would invest more than $150 million over the next five years to help find an estimated 800,000 undocumented orphan wells, reuse those we can for beneficial purposes and ultimately close all of the rest more effectively and affordably. While partisan politics seem to divide the Capitol these days, it is exciting to see leaders on both sides of the aisle come together to address orphan wells.
