A full day of negative temps in #Denver down to -15F, and our #heatpump has no problem keeping things toasty. This with a 1900 house and old leaky windows, too! No gas necessary ⚡️

Today, the U.S. Department of @Energy (DOE) Industrial Technology Innovation Advisory Committee (ITIAC) released our first report containing recommendations on how DOE can accelerate a transition to clean, competitive U.S. #manufacturing. Check it out at

Want a deeper dive into what made it into the final 45V Clean Hydrogen Production Tax Credit rules? In a new blog, we share six insights on the electrolytic hydrogen side, covering pros/cons for emissions integrity, investment risk, and industry viability: https://t.co/dJDvvYyd1V

NEW: The U.S. Treasury's final 45V Clean Hydrogen Production Tax Credit rules are out. In my new @_LatitudeMedia op-ed, I argue these rules are a remarkable compromise that can spur a domestic clean hydrogen industry--but stakeholders must unite: https://t.co/Dzi7NkFamg

Read guest author @jeffrissman's opinion piece on five practical policies that policymakers should adopt to accelerate clean industry in the United States:

Great coverage of what's at stake with major upcoming U.S. hydrogen policy decisions in @CanaryMediaInc by @jeffsaintjohn -- for H2 to be a viable climate solution, we need it to be truly clean and strictly directed to uses where it has a competitive edge: https://t.co/5Ih5PpdBU3

🌱Policy should boost efficiencies in fertilizer application/management and pursue techs that reduce the need for chemical fertilizers, but clean hydrogen is necessary for climate-friendly ammonia production. Read our "Hydrogen for Ammonia" factsheet:

⛽️Oil refining must decline with time (as it has severe public health impacts), but hydrogen is a key part of this process; thus, it's critical to switch from dirty to clean H2 to reduce its climate pollution. Read our "Hydrogen for Refining" factsheet:

🏗️Hydrogen can start cleaning up steel today and prevent new investments in coal-based steel. Emerging all-electric technologies are on the way but are 10-20 years out, meaning we can't wait to get started. Read our "Hydrogen for Primary Steel" factsheet:

🛢️Hydrogen can be paired with captured carbon to build chemicals needed in everyday life. However, lasting pollution impacts suggest it will be critical to cut total demand, incl. via material efficiency. Read our "Hydrogen for Petrochemicals" factsheet:

✈️Hydrogen can be used to make sustainable aviation fuels (SAF) needed for long-distance flights. Notably, "PBtL" holds great potential to use H2 to boost SAF output from biomass. But, contrail challenges remain. Read our "Hydrogen for Aviation" factsheet:

🚢Hydrogen can be used to make two alternative fuels (methanol and ammonia) enabling long-distance marine trips. However, battery electric ships will likely beat hydrogen ships for shorter-haul shipping. Read our "Hydrogen for Marine Shipping" factsheet:

🔋Hydrogen can serve long-duration energy storage needs but carries public health risks. It's critical for any H2 power plants to be able to use 100% H2 with ultra-low to zero NOx emissions. Read our "Hydrogen for Seasonal Electricity Storage" factsheet:

🔥Hydrogen may be limited to opportunistic retrofits for providing high-temperature heat. Directly electrifying industrial heat (via heat pumps, thermal batteries, etc.) should take priority. Read our "Hydrogen for Industrial Process Heat" factsheet:

🚛Electric trucks are cheaper than fuel cell options, with the performance gap narrowing. They are increasingly capable of handling the vast majority of tasks, incl. in long-haul, heavy-duty trucking. Read our "Hydrogen for Heavy-Duty Vehicles" factsheet:

🚗Electric vehicles have insurmountable advantages over hydrogen fuel cell vehicles--including on efficiency, performance, cost, vehicle sales, and charging infrastructure deployment. Read our "Hydrogen for Light-Duty Vehicles" factsheet: https://t.co/gsosOLvSkL

⚡️Hydrogen can't compete with direct clean energy use or batteries for daily power needs. Using H2 this frequently would imply electrolyzing it at the same times as it's being burned for power. Read our "Hydrogen for Day-to-Day Power Generation" factsheet: https://t.co/4xpkCiSw9f

🏘️Hydrogen has at best a negligible role to play in decarbonizing buildings. Gas utility proposals for hydrogen blending do not reflect H2's value as a climate solution, instead delaying meaningful actions. Read our "Hydrogen for Buildings" factsheet: https://t.co/vyo1yJ6L9m

🚨NEW: Today, we published a paper titled Hydrogen Policy's Narrow Path Forward: Delusions & Solutions. It's dense with information but organized for readability, including a series of standalone 2-page overviews covering 12 potential hydrogen end uses. https://t.co/UHtgCCG689

The paper includes two sets of policy recommendations: tools to boost hydrogen's uptake in high-value uses, and measures to minimize risks of H2's low-value uses. This thread is too long already, so I'll cover these another time. For now, read them here: https://t.co/UHtgCCG689

Key Finding 6: Hydrogen's uptake in high-value uses will require targeted demand-side policies. Supply-side subsidies alone will not ensure this outcome (and may make better alternatives for low-value uses look worse). Policymakers need to intervene.
