Products
Sprouter Energy is part of the movement towards a climate-neutral economy, transitioning away from fossil fuel energy to a 100% environmentally sustainable zero-emission energy.
Through the process of Anaerobic Digestion we produce Green Biogas with two primary subproducts, Green Biomethane and CO2. Other non-gas by-products are Digestate as fertilizer, Heat from the anaerobic process and Potable Water.
​
This range of products separates Sprouter Energy from other renewable energy creators in providing for economic diversity through multiple revenue opportunities.
Green Biogas By-Products
Green Biomethane - as electricity
​
Use in a CHP unit on site to convert the green biomethane in electricity.
​
The electricity can be sold directly into existing power grids or to individual customers such as industry, agriculture or municipalities.
Green Biomethane - as methanegas
​
Biomethane can be refined on site to be used as a natural gas replacement having the same energy properties though being 100% environmentally friendly.
​​
The biomethane gas can be sold directly into gas grids or to individual customers such as industry, agriculture or municipalities.
​​
Biomethane gas can be used for residential or commercial heat, for industrial purposes and to power the regular and heavy transportation sectors as a petrol and diesel replacement.
Green Biogas - as green hydrogen
​
Biogas converted into biomethane which can generate electricity to power an Electrolyzer which converts water into green hydrogen gas.
The process is 100% environmentally friendly as it only used water and green biomethane.
​
Green hydrogen has multiple uses especially in heavy industry and heavy transportation where electric option are not viable due to storage issues or energy conversion.
Green Biogas - as CO2
​
While CO2 waste gas is a contributor to greenhouse gas, purified CO2 is a product which is used on a daily basis. CO2 is used for medical purposes, in the food industry, in manufacturing, packaging, agriculture and numerous other areas.
​
CO2 can also be used as an energy carrier for other gasses such as methane, used for energy storage or for the further enhancement of the anaerobic digestion process to increase energy yields.
Anaerobic Digestor By-Products
Digestate - fertilizer
​
Digestate is the physical material remaining after the AD process and is mainly used as fertilizer. After processing it is a wet mixture which can be separated into liquids or solids, both are extremely rich in nutrients.
The digestate is an excellent fertilizer containing all necessary nutrients and micronutrients for farming, includes nitrogen, phosphorus and potassium and is completely organic.
Digestate is better for the environment than chemical fertilizers as it reduces the amount of phosphorus needed be to be mined, reduces nitrogen leaching into ground water versus unprocessed organic material, creates a reduction of animal and plant pathogens and reduces the spread of invasive weeds thus fewer chemical sprays.
AD Process - heat
​
The Anaerobic Digestion process creates a substantial amount of heat.
Surplus heat produced by biogas combustion in a combined heat and power (CHP) unit is the most common heat source within an AD plant.
Other processes which result in residual, usable heat include digestate pre-heating, digester heating, pasteurisation (either before or after digestion), electricity generation via the CHP, during the biogas upgrading to biomethane as the heat can be captured and reused.
This heat can be used locally for municipal or industrial heating or can be converted for energy storage.
AD Process - water
​
While not normally recognized as a by-product of Anaerobic Digestion, water is a major result of the process and can be reused in the Anaerobic Digestion process or fed back into local systems.
The Anaerobic Digestion process can be used as an important step for the prevention of water pollution by reducing organic solid waste and wastewater disposal, for saving water by enabling water reuse, for fossil energy saving and hence water saving, and for progressing from water conservation to resource conservation.
Green Hydrogen in Heavy Industry
& Heavy Transportation
Heavy industry requires high temperature for many of its processes, temperatures which are not achievable using electricity. Heavy transport such as aviation, shipping, and road freight cannot use electricity due to storage capacity and energy conversion ratios. The solution is green hydrogen and green biomethane for both heavy industry and heavy transport. Green biogas produced by an AD unit can be converted into green biomethane which is as powerful an energy carrier as natural gas and suitable for nearly all heavy industry energy requirements. So too is the green hydrogen, derived from the same AD / green biogas process. These products are applicable to the long-haul transportation sector in providing options of either green methane or green hydrogen as the future fuel for heavy trucks, aviation and ships. Recently some of the worlds largest shippers have begun testing hydrogen-fuelled marine engines on ocean-bound carriers. As these heavy industries begin switching to zero-emission fuels, production for green biomethane and green hydrogen will be in high demand. Unlimited green hydrogen and biomethane can be created from the energy derived during the anaerobic digestion process and as such Sprouter Energy is positioned to support both heavy industry and heavy transport.
