Arizona Project Will Advance DOE’s Hydrogen Shot of $1 per 1 Kilogram of Clean Hydrogen in One Decade
WASHINGTON, D.C. — The U.S. Department of Energy (DOE) today announced $20 million in funding to demonstrate technology that will produce clean hydrogen energy from nuclear power. This innovative approach will allow clean hydrogen to serve as a source for zero-carbon electricity and represent an important economic product for nuclear plants beyond electricity. The project, based in Arizona, will make progress on DOE’s H2@Scale vision for clean hydrogen across multiple sectors and help meet the Department’s Hydrogen Shot goal of $1 per 1 kilogram in one decade. This announcement is part of a week-long celebration of Hydrogen and Fuel Cell Day that culminates on October 8.

ATLANTA (April 5, 2021) – The ASHRAE Epidemic Task Force released an updated, unequivocal statement on the airborne transmission of SARS-CoV-2 in buildings.
ASHRAE has released the following statement: “Airborne transmission of SARS-CoV-2 is significant and should be controlled. Changes to building operations, including the operation of heating, ventilating, and air-conditioning systems, can reduce airborne exposures." It replaces the April 2020 statement that said airborne transmission was “sufficiently likely” that airborne precautions should be taken. At that time both, the World Health Organization (WHO) and the Centers for Diseases Control (CDC), contended that transmission of SARS-CoV2 was by droplet and fomite modes, not airborne. Subsequently, both have acknowledged the risk of airborne transmission indoors. “This may seem like a small step, but we feel it is important to leave no doubt about our position, given the muted support for ventilation and filtration as important tools in the effort to stop the pandemic, from some organizations that should be leading more strongly,” said William P. Bahnfleth, Ph.D., P.E., ASHRAE Epidemic Task Force chair. The ASHRAE Epidemic Task Force has been developing and disseminating guidance for the control of airborne transmission of SARS-CoV-2 since its formation in March 2020. “ASHRAE volunteers have played a huge role in evaluating evidence and developing detailed guidance to improve indoor environmental quality,” said Bahnfleth. “The public, globally, is benefitting from the volunteer efforts of some of the most knowledgeable scientists and engineers in our field and this updated guidance is proof of it.” To view the complete airborne transmission statement and other COVID-19 resources, visit ashrae.org/COVID-19.

ATLANTA (February 2, 2021) – As the performance of many HVAC systems in buildings are still being evaluated, the ASHRAE Epidemic Task Force has updated its reopening guidance for HVAC systems to help mitigate the transmission of SARS-CoV-2.
“The Building Readiness Guide includes additional information and clarifications to assist designers and commissioning providers in performing pre- or post-occupancy flush calculations to reduce the time and energy to clear spaces of contaminants between occupancy periods,” said Wade Conlan, ASHRAE Epidemic Task Force Building Readiness team lead. “New information includes the theory behind the use of equivalent outdoor air supply, method for calculating the performance of filters and air cleaners in series, and filter droplet nuclei efficiency that help evaluate the systems’ ability to flush the building.” This free webinar will provide valuable information to those involved with or responsible for the operation of HVAC in hospitals and healthcare installations. We urge you to attend.
