Low battery self-discharge: the hidden secret to long operating life

While much media attention has been focused on extending battery operating life through the use of low-power chipsets and communication protocols, the potential energy savings gained from all of these schemes fails to compare with the energy lost to annual self-discharge.

This graphic shows two ways to achieve 85 units of energy for cannabis production. On the left, electricity is provided by the electric utility. The electric utility or natural gas supplier, or both, supply energy needed for heating, cooling and dehumidification. Depending on whether the facility needs heating, between 266 and 300 units of energy are needed to supply 85 units of available energy. On the right, CHP generates needed electricity. Resulting thermal waste energy is used for heating, hot water, cooling and dehumidification. Only 100 units are needed to achieve 85 units of available energy. Courtesy: Energy Solutions Center

Producing RNG through power-to-gas technology

Power-to-gas (P2G) technology can help produce renewable natural gas (RNG) without creating greenhouse gas emissions, but there are questions about how to make P2G work, mostly related to system optimization and electric grid integration; projects in the field and university research are working to answer those questions.
