For the U.S. Army, creating secure sources of energy is an important driver for its net-zero goals. Critical military missions are at a high risk of failure in the event of an electric grid failure, according to a Defense Science Board report.
“Energy security, surety, and reliability, as well as overall physical security of the site, must be maintained or enhanced by the installation’s energy system,” says an Army guide to net zero.
“For example, a biomass-fueled power system may be unsuited to some sites due to off-site truck traffic required to bring in fuel,” the document says. “On the other hand, the ability to meet an installation’s critical load using on-site renewable sources (e.g., landfill gas, geothermal power, solar energy) in an islanding mode may greatly enhance energy security.”
On-site energy supplies and smart microgrids can reduce the risk of operational degradation due to blackouts, and may become an increasingly important strategic concern, the Army says.
