[Episode #224] – US Hydrogen Tax Credits

Clean hydrogen is expected to be an essential pathway to decarbonizing the economy. The US Inflation Reduction Act of 2022 offered a generous tax credit known as “45V” for clean hydrogen production, but left it to the US Treasury Department and the IRS to define the rules for earning the credit. So they sought input on the rules by issuing an RFI (Request for Information), and aspiring hydrogen industry players, think-tanks, policy advisors, and the public submitted their guidance. After the proposed rules were issued, tens of thousands of additional comments were filed. A final comment period on the rules ended on May 10.

Eric Gimon of Energy Innovation, a San Francisco-based clean energy think tank and a major contributor to the 45V discourse, previously discussed their guidance for the IRS in Episode #192.

In this episode, Eric rejoins us to discuss the proposed final rules, and their team’s comments on them. On the whole, they are optimistic that the rules will spur robust investments in the burgeoning US green hydrogen sector. With potentially hundreds of billions of dollars in tax credits on the line, it’s important to get the details right, so we explore them in depth in this 90-minute discussion—which earned a rare off-the-charts Geek Rating of 11. We also address concerns and criticisms raised by prospective hydrogen producers whose projects may not align with the new regulations.

Guest:

Eric Gimon consults as a technical expert, research scholar, and policy adviser with Energy Innovation, where he works with the Electricity team to develop innovative thinking on policy solutions for clean, reliable, and affordable electric power in the U.S. More specifically, Eric works on questions of renewable energy integration, both in the context of today’s challenges as well as for future pathways

[Episode #192] – When is Hydrogen ‘Clean’?

The Inflation Reduction Act of 2022 introduced two tax credits to encourage the development of a domestic clean hydrogen industry in the United States. These tax credits can potentially be worth billions of dollars and are based on a sliding scale, depending on how ‘clean’ the hydrogen production is. The less greenhouse gas emitted during production, the larger the tax credit.

However, measuring and accounting for the greenhouse gas emissions from a hydrogen production facility can be complicated, especially when the electrolyzer producing the hydrogen is in a different location on the power grid from the renewable power plant that powers it. So complicated that you pretty much have to be a grid power expert to even begin figuring these calculations out.

To address such sticky questions of hydrogen production tax credit eligibility, the US Internal Revenue Service (IRS) requested comments to shape how they will measure and account for related emissions. One of the respondents was the San Francisco-based clean energy think-tank Energy Innovation, which submitted a very thoughtful, 25-page response outlining some of the key issues the IRS should understand, the criteria it should consider, and some policy recommendations, as well suggestions for preventing attempts to game the tax credit system.

In this highly technical episode, we welcome back to the show Eric Gimon, one of the Energy Innovation authors, to review their response to the IRS. And this discussion reveals not just how to ensure that the billions of dollars of tax credits will go to projects that actually reduce emissions, but also important insights about everything from how we go about building new renewable power plants, to the varying carbon intensity of the power grid, to the business case for building electrolyzers to produce green hydrogen.

[Episode #156] – 6-Year Anniversary Show

In this sixth-anniversary show, we welcome back energy researcher Jonathan Koomey to help us review some of the hot topics in energy transition over the past year.

Topics in this discussion include:

  • The energy elements of the bipartisan infrastructure bill that passed the Senate, and how they stack up against the actual infrastructure needs of the US.
  • Highlights from the new climate assessment report from the IPCC, and the disconnect between how that modeling framework is structured, and what policymakers and journalists really need. We also try to identify how climate scientists can be more helpful in communicating the path the world is currently on.
  • The case for and against divestment and other supply-side strategies to reduce the consumption of fossil fuels.
  • The zombie theory of ‘value deflation’ in solar, and why it’s mistaken.
  • Corruption in the nuclear industry, and why climate hawks must start getting more discerning about who they are backing in the struggle to take action on climate change.
  • The energy requirements of the Internet and Bitcoin mining.
  • A new tool to explore the EIA’s vast stores of data.

In the news segment, we review the ongoing efforts in Congress to electrify the US Postal Service vehicle fleet; we update two stories about corruption associated with the US nuclear industry; we hail the world’s first production of a batch of steel without using fossil fuels; we have a look at the world’s largest battery storage system; and we note a major blow to the credibility of “blue hydrogen.”
