Energy storage power supply for agricultural use

What is pumped storage power station?

The pumped storage power station has the ability to regulate and store energy, which can regulate the output of new energy generation and alleviate the conflict between new energy generation and irrigation demand for electricity. A complementary system for wind-PV and pumped storage can be constructed.

Can agricultural land be used for energy co-production?

To relax land constraints, we propose the concept of ‘aglectric’ farming, where agricultural land will be sustainably shared for food and energy co-production. While wind turbines on agricultural land are already put into practice, solar power production on agricultural land is still under research.

What are the different types of energy storage systems?

Energy storage systems include electric batteries (stationary as well as in electric vehicles), pumped hydro systems, power-to-heat systems such as hot water boilers or heat pumps that can convert excess electricity to heat to be stored for later use and power-to-gas systems that convert excess electricity into hydrogen.

Why do farms need a battery?

A battery can allow farms to get off-grid, e.g. in case of a temporary power outage (as back-up or UPS – Uninterruptable Power Supply). Through the use of batteries, farms can offer flexibility to the wider energy system (including through aggregators) for supporting the grid.

How can integrated food-energy systems improve land use?

Integrated food-energy systems, which fully account for the nexus of energy, food and water will optimise land use and advance circularity in energy-food linkages, recognising and addressing trade-ofs and harnessing synergies among the sectors. Several common challenges exist for scaling up renewable energy applications in food systems.

How can solar aglectric farms improve agricultural output?

Adjusting the intensity, spectral distribution and duration of shading allows innovative photovoltaic systems to achieve significant power generation without potentially diminishing agricultural output. The feasibility of solar aglectric farms has been proven through shadow modelling.
