Our work: Establish energy farms for the production of biogas and electricity with cactus. (opuntia)

Elqui Global Energy has been advising the public and private company present in South Africa, Colombia, Argentina, India, Spain, Chile and Mexico with projects developed or in development.

Cactus biogas represents an alternative for developing countries where other crops are not possible.

 

 

alternatives use of nopal

 

The nopal as a raw material has applications both for animal and human food, as well as in the production of energy. Its extensive international distribution allows its cultivation from the south of the USA to places as remote as Cape Town in South Africa. The low water requirements and its easy multiplication make it the ideal raw material for bioenergy projects in marginal areas

 

In low-income countries such as Nigeria, Angola, mainly Africans, it is an alternative for energy and food production in degraded soils.

 

 

v  Human Food

Ø  Fresh nopalitos.

Ø  Pickles in brine and vinegar

Ø  Cactus flour for the preparation of baked goods such as tortillas.

 

v  Animal Feed

Ø  Nopal fresh direct feed.

Ø  Nopal flour to supply rations in goats, cows, horses.

 

v  Vermiculture

Ø  Obtaining earthworm humus as an organic fertilizer.

Ø  Development of protein concentrates based on worm meat for animal feed.

 

v  Energy production

Ø  Obtaining biogas for heating and equipment operation.

Ø  Electricity for internal electricity supply or external sale.

Ø  Obtaining liquid effluent with high nitrogen content for use as fertilizer in technified irrigation.

 

v  Obtaining carbon credits.

Why use nopal?.

 

The cactus has excellent molecular characteristics which allows to deliver a large amount of biogas in a very short time, in comparative terms for the same volume of biogas nopal degrades 10-15 times faster than animal manure, it allows a single computer is 10 to 15 times more productive. Also it not produces hydrogen sulfide which when burned in contact with air becomes sulfur oxides.

 

What is the yield per hectare?

 

Cactus is an extraordinary plant with a modern irrigation, two or three crops per year, can deliver continuously from 800 to 1,200 tons of biomass / year, in terms of energy equivalent to 35 kw / ha x 24 hx 365 days.

 

What is the cost of a standard project?

 

Assuming there is water and the land is suitable for development of nopal. For a project of 1 MW has cost some US1.500.000 including plantations, equipment, etc. facilities assessment, the payback assuming a value of power sale dollars US80 / MWh would be within 2 years. 

 

 

ADVANTAGES OF CACTUS

 

v  Continuous power generation 24 X 365 days.

v  Production of biogas and electricity.

v  No sulfur oxides or particulate.

v  Low maintenance.

v  Overall plant efficiency 80-90%

v  Generates soil, organic fertilizers.

v  Change the microclimate retaining water in the soil.

v  Extracts carbon dioxide atmosphere.

v  Lifespan 20 years.

v  Allows the sale of carbon credits.

v  Totally organic process

v  Fast implementation of project

v  Generates permanent jobs for sowing harvest, and process plants.

v  Allows the opening of new markets to be considered a green company that cares.
