Video: Web tool weighs the merits of geothermal heat pumpsS. Himmelstein | January 18, 2022
A web tool previously developed by the U.S. National Renewable Energy Laboratory (NREL) enables users to cost-effectively tap renewable energy resources by optimizing system sizes and battery dispatch strategies.
A new module added to the Renewable Energy Optimization and Integration Tool (REopt) is designed to simulate the impact that converting conventional heating and cooling systems to geothermal heat pumps (GHPs) may have on on-site consumption of fuels and electricity, utility costs and carbon dioxide emissions. REopt’s existing distributed energy resource models can be applied to study the impact and interaction of a GHP retrofit with solar photovoltaics, batteries, combined heat and power, and other technologies.
REopt analyzes site-specific heating and cooling needs and can also be used to estimate how long a system can sustain critical loads during a grid outage, informing resiliency strategies.
