Can agriculture be used to supply hydropower

image

The Colorado Energy Oce has identi -fied three components of agricultural water conveyance that have the capacity to har-ness hydropower: 1) on-farm pressurized irrigation systems, 2) conduit drops on ir-rigation ditches, and 3) existing agricultural dams. This publication will only address on-farm pressurized irrigation systems. Small scale hydropower generation, also referred to as micro-hydro, is a way of harnessing the energy of flowing water and putting that energy to mechanical or electrical use. Typical small-hydro systems are designed to generate 2 megawatts (MW) of energy or less. Harnessing the energy of water as it flows downhill has long been used to power industrial and agricultural operations. Flour mills, for ex-ample, used the water of a flowing stream to turn a waterwheel and mechanically drive the flour grinders. Today there are new technologies that allow energy to be captured from moving water and used to mechanically turn a center pivot, or even create electricity. The main benefit of small hydropower generation is the ability to use a device, called a turbine, to extract energy from moving water and convert that energy to power or electricity. Here it is important to distinguish between power, energy, and electricity. Power is the amount of work that gets done over time, energy is the ability to do work, and electricity is a charged cur-rent. To better understand how power and electricity are created we need to first look at the source of this energy.

Small on-farm hydropower generation offers an irrigator the opportunity to reduce their electrical costs which, depending on the size of the farm, could significantly reduce overall costs.

Why Hydropower is a good source of energy?

Facts about hydropower Renewable hydropower is a reliable, versatile and low cost source of clean electricity generation and responsible water management. Modern hydropower plants are helping to accelerate the clean energy transition, providing essential power, storage, flexibility and climate mitigation services.

How much more hydropower do we need to save the planet?

According to the International Renewable Energy Agency (IRENA), the world’s existing hydropower capacity will need to grow by around 60 per cent by 2050 to reach 2,150 GW to help limit the rise in global temperature to well below two degrees Celsius.

What is hydropower?

Hydropower, or hydroenergy, is a form of renewable energy that uses the water stored in dams, as well as flowing in rivers to create electricity in hydropower plants. The falling water rotates blades of a turbine, which then spins a generator that converts the mechanical energy of the spinning turbine into electrical energy.

What are dams used for in hydropower?

Only a small minority of the world’s dams are built for hydropower, with the majority used for irrigation, water supply, flood control and other purposes.

Why isn’t hydropower used more?

One reason hydropower hasn’t taken more of the U.S. energy market is that it has a high investment cost, it requires a large amount of fuel, and is limited to areas near bodies of water. The amount of hydropower that can be generated, unfortunately, is also dependent on the amount of available water.


Why can’t countries rely on hydroelectric power plants alone?

Hydro plants need a consistent supply of water and a large amount of land. Some countries have plenty of these resources; others do not. Poorly planned hydropower can also cause more problems for the climate than it prevents. Hydro plants need large reservoirs to provide a steady stream of water.


Is hydroelectric plants are environment friendly or not?

Hydropower is a climate-friendly energy source, generating power without producing air pollution or toxic by-products. Using hydropower avoids approximately 200 million metric tons of carbon pollution in the U.S. each year – equal to the output of over 38 million passenger cars.


What can we use instead of dams?

Geothermal, tidal, and wave energy are alternatives, the potential of which we have not even glimpsed. The promotion of large dams only delays adoption of the truly clean energy solutions that Latin America and the planet desperately need.


Is Hydro Electricity sustainable?

AND RENEWABLE. Hydropower draws energy from falling or flowing water and converts it into electricity, without consuming, wasting or depleting water in the process. Hydropower produces no air pollutants and has ultra-low greenhouse gas emissions.


Does hydropower create pollution?

Hydropower generators do not directly emit air pollutants. However, dams, reservoirs, and the operation of hydroelectric generators can affect the environment. A dam that creates a reservoir (or a dam that diverts water to a run-of-river hydropower plant) may obstruct fish migration.

Is hydroelectric energy expensive?

At US$0.05/kWh, hydroelectricity remains the lowest-cost source of electricity worldwide, according to a recent report by the International Renewable Energy Agency, entitled Renewable Power Generation Costs in 2017.


Why is hydropower considered a renewable resource?

Worldwide, hydropower is the most widely used renewable energy resource due to its significant advantages over other renewable resources: high energy density, low cost and reliability in particular. Hydropower plants are available from very small sizes of only few Kilowatts (kW) to multi-Gigawatts (GW). Small hydropower plants, generally in kW range, are used for rural electrification in many countries and have high potential to be integrated into the agriculture value chain in those locations.


How does a hydro turbine work?

Because it is powered by kinetic energy and not with potential energy it is known as a so-called “zero-head” or “in-stream” turbine. As such, no dams and/or height differences are necessary for the operation of this device; the course of a river remains in its natural state and no high investments in infrastructure are required. Because the amount of kinetic energy (velocity) varies from river to river, the capacity of an in-stream turbine ranges: from a minimum of a few watts to a maximum of 5 kW.


What is small hydropower?

Small hydropower generation is the most feasible when added to existing wa-ter delivery infrastructure and an existing, decreed water use. In this sense, the ad-ditional use of the water for hydropower generation would be considered an “in-cidental and non-consumptive use” and would not require a new water right, so long as the hydropower is only generated during the deliveries for the original and decreed water use. For example, if a small hydropower system is added to the water delivery infrastructure of a center pivot, the water used in irrigation could also be used to generate electricity without needing a new water right as long as the amount of water used does not exceed the amount of water decreed for irriga-tion. Unless a new water right is issued to divert more than the historical amount for irrigation, the amount of water diverted to irrigate, and incidentally to run a center pivot, must remain the same as before the small hydropower system was installed. It is important to note that relying on already-decreed water could affect the availability of power production, depend-ing on the seniority of the water right. If new diversions are needed for the sole purpose of generating electricity, then a new water right would need to be obtained. If you are unsure if a new water right is needed, contact the Colorado Division of Water Resources to clarify.


Is hydroelectric power regulated in Colorado?

Although small hydropower genera-tion may be easier to implement than be-fore, hydroelectric facilities are still subject to regulation by the State of Colorado and the FERC. By streamlining regulatory pro-cesses in 2013, the FERC offered irrigators the ability to add a hydroelectric facility to an irrigation ditch or pipeline where the primary purpose of the ditch or pipeline is to deliver irrigation water to fields rather than generating electricity. Mechanical hydropower projects do not produce electricity and therefore do not need to go through the FERC permitting process.Hydroelectric projects are only feasible because of the Hydropower Regulatory Eciency Act of 2013. Before this Act was signed, the FERC permitting pro-cess would take years and cost tens of thousands of dollars for even the small-est hydroelectric projects. Among other things, the Act exempts certain conduit hydropower facilities from the licensing requirements of the Federal Power Act
