House Dems introduce clean energy bill for net zero
Democratic leaders in the House last week introduced the Climate Leadership and Environmental Action for our Nation’s Future Act (the CLEAN Future Act, or H.R. 1512), a nearly 1,000-page piece of climate change–focused legislation establishing, among other things, a federal clean electricity standard that targets a 50 percent reduction in greenhouse gas emissions from 2005 levels by 2030 and net-zero emissions by 2050.
The bill, a draft version of which was released in January 2020, presents a sweeping set of policy proposals, both sector-specific and economy-wide, to meet those targets. The final version includes a number of significant revisions to bring the legislation into closer alignment with President Biden’s climate policy campaign pledges. For example, the bill’s clean electricity standard would require all retail electricity suppliers to provide 80 percent clean energy to consumers by 2030 and 100 percent by 2035. (A six-page fact sheet detailing the updates is available online.)

Recent developments in helicon ion sources and Inertial Electrostatic Confinement (IEC) device performance at UW-Madison have enabled low pressure (< 50 torr, 6.7 mPa) operating conditions that should allow the 3He-3He fusion reaction to be observed in an IEC device. An ion source capable of delivering a ~ 10 mA 3He ion beam into an IEC device with minimal neutral gas flow has been designed and tested. Furthermore, a new IEC device that has never been operated with deuterium has been constructed to avoid D-3He protons from obstructing the 3He-3He reaction product spectrum, and to minimize Penning ionization of deuterium by excited helium, which in the past is suspected to have limited the ionized density of He. These developments make it possible to study beam-background 3He-3He fusion reactions with > 300 mA recirculating ion currents.
