Regenerative agriculture is a way of farming that aims to restore and revitalize land to improve soil health and boost biodiversity. The ultimate goal of regenerative agriculture is to establish a sustainable and robust food system that nourishes a growing population while enhancing the land and communities that depend on it, sequestering carbon, reducing greenhouse gas emissions, and increasing biodiversity.
In part 3 of Agrihub’s 6-part video series, Host Dan Cloutier, Director of Regenerative Agriculture, explores leveraging energy efficiency for profit and environmental goals. In this video, we look at improving energy efficiency in barns through a regenerative agricultural lens. Dan Cloutier goes over the importance of climate batteries and cogeneration in order to achieve net zero and other sustainability targets.
A traditional battery stores electricity, whereas a climate battery stores heat that can be used in a greenhouse. A climate battery greenhouse uses the earth’s thermal mass to heat and cool a greenhouse, similar to a conventional geothermal system. However, unlike regular geothermal systems, the climate battery greenhouse relies on fans to circulate heated air through corrugated pipes rather than complicated and costly heat pumps.
Cogeneration, also known as combined heat and power (CHP), is the simultaneous production of electricity and heat from a single fuel source. This is typically achieved by using a heat engine, such as a gas turbine or internal combustion engine, to generate electricity while capturing the waste heat from the engine to produce steam or hot water for heating. Cogeneration is considered a more efficient and sustainable method of energy production, as it can lead to significant energy savings and reduced greenhouse gas emissions compared to traditional methods of electricity generation.
