Happy #ClimateDay: FACT SHEET ➡️ "President Biden Takes Executive Actions to Tackle the Climate Crisis at Home and Abroad, Create Jobs, and Restore Scientific Integrity Across Federal Government" whitehouse.gov/briefing-room/…
The order "makes clear that both significant short-term global emission reductions and net zero global emissions by mid-century – or before – are required to avoid setting the world on a dangerous, potentially catastrophic, climate trajectory."
"The order clearly establishes climate considerations as an essential element of U.S. foreign policy and national security."
We know how to make clean energy cheap. We've done it several times: wind, solar, LEDs, lithium-ion batteries. This decade, with proactive investment, governments and private sector innovators can finish the job and complete a toolkit for a prosperous net-zero emissions economy.
Our to do list:
-Advanced geothermal & nuclear, H2 combustion turbines, long-duration energy storage, cheaper HVDC transm.
-Hydrogen from electrolysis, gas reforming w/CCS & biomass gasification w/CCS
-Synthetic fuels
-CCS for cement
-Direct reduction of iron
-Direct air capture
None of these are radical breakthrough techs that need to come from scientific labs. These are all techs that have been demonstrated at pilot or commercial scale. We know how they work. Now we need to make them cheap, low-risk, scalable, just as we did for wind, solar, batteries
So let's talk about Budget Reconciliation, that 'one weird trick' the Senate majority uses to bypass the filibuster on measures related to revenue, spending and taxes. An explainer: budget.house.gov/publications/f…
Republicans used reconciliation in 2017 to pass the Trump/McConnell tax cuts that almost entirely benefited the wealthy & corporations, added $1.9T to the deficit, and killed the penalty for not getting health care. (They did pretty much the same thing in 2001, 2003, & 2006 btw).
Democrats can now use reconciliation to: expand unemployment insurance & $2,000 checks & $ for small biz to help Americans weather the pandemic, $ for vaccinations, rebuild our infrastructure, invest in US manufacturing, build clean energy, and tax the uber wealth. Seems fair.
Fabulous news! The MA Legislature passed the #Climate Roadmap Act, which updates the 2008 Global Warming Solutions Act and provides statutory requirement to reduce GHG emissions to net-zero by 2050, in line w/@MassGovernor's 2050 Roadmap released last week
In Oct 2019, I helped organize a letter from 37 scholars & experts "to confirm that the scientific underpinning for [the 2050 Roadmap Bill] is sound, technologies exist to put us on a path to achieving the goals, and there are viable policy pathways for achieving the targets."
My work on electricity decarbonization has demonstrated the importance of what I call "firm" low-carbon electricity generation technologies to enabling an affordable and reliable 100% carbon-free electricity system. See doi.org/10.1016/j.joul… & seminar
This work demonstrates that, under certain conditions, natural gas power plants w/CCS or burning hydrogen (possibly derived from methane reforming w/CCS) *could* play a firm low-carbon role in this 100% carbon-free electricity mix. THIS HAS NOTHING TO DO WITH GAS APPLIANCES.
They're right (with a few exceptions). Here's why...
We already have over 540 gigawatts of natural-gas fired generating capacity in the U.S. today. That's enough to meet about 2/3 of our nationwide peak in electricity demand. That's plenty of capacity to help manage the variability of weather-dependent wind & solar as they scale up
Those existing natural gas power plants will play a key role in the near-term as what I've termed "firm" generating capacity: available on demand (dispatchable), any time of the year, for as long as needed. (For more on firm generation, see doi.org/10.1016/j.joul…)
