POSITIVE ENVIRONMENTAL IMPACTS FROM OUR OPERATION

CLIMATE IMPACT:

The amount of Methane CH4 recovered that would have been lost to global warming and the amount of Carbon Dioxide CO2 sinked and avoided per year.
Our process is based on negative emissions technologies. In other words, the fuel we produce (Biomethane) is the same fuel we use through the business for the harvesters, generator, compressors, trucks and all other support vehicles.

The amount of biomethane recovered and turned in to a clean fuel as BioLNG. In full production HyaPOWER will produce about 50 000t of biomethane per year that would have otherwise been lost and contributed to global warming due to the natural anaerobic decay of the biomass. Bearing in mind that the Global Warming Potential (GWP) of CH4 is 85 times higher than CO2 over a 20-year period. In other words, 50 000t of methane has the same global warming potential as 4 250 000tCO2e per year.

The CO2 that recovered from the biogas upgrading process will be use in our green houses as an Aerosol fertilizer and the plant will intern produce oxygen. Our main product will be BioLNG which can be used in different ways to generate energy. Therefore, we decided to calculate the amount electricity and CO2 emissions we would be able to generate using the total amount of BioLNG we would have produced per year. And then compare it to the CO2 emissions produce for the same amount of electricity generated by our coal power utility Eskom. If we would use our total daily production of 8000GJ of BioLNG to fuel 6x Combined Cycle Gas Turbine Generators, we would be able to produce 55MWh at -0.220kg CO2e/kW/h with a 60% Efficiency compared to the South African Eskom Coal fired Power stations at 1.03kg CO2e/kW/h with <30% Efficiency.

CO2 Emission avoided tCO2e/year = ((Eskom emissions – HyaPOWER emissions) x Power produced per hour x Hours per year)/ 1000 000

In full production with 55MWh we will be able to avoid 602 250 tCO2e per year. Plus, the CO2 that was extracted from the atmosphere by the water hyacinth we have harvested which calculates to about 30 000t per year. Including the CO2 savings from the production process we will be able to avoid and sink a total of about 632 000 tCO2e per year.

This process will enable HyaPOWER to be an energy company with a negative GHG emission footprint and make a huge impact on climate change. More information about the calculation method, the formula and our sources are available on request.

 

ENVIRONMENTAL IMPACT:

The ability to restore and maintain Water Quality, and biodiversity on the back of the pollution entering the dam on a yearly basis.  

The pollution brings in high levels of nutrients (Nitrates & Phosphates), this creates a state of Eutrophication which is the catalyst behind the high growth rate of the Hyacinth. As the hyacinth grows, they extract these nutrients from the water. Currently as the hyacinth grow and die and sink to the bottom increasing the nutrient level in the dam. This creates a downward spiral as the pollution increase, it is currently 7x higher than what is deemed acceptable. By harvesting the hyacinth, we will be able to break this downward spiral and reduce the nutrient level in the dam. Over time we will be able to restore the water quality and the ecosystem that depends on it. It will also reduce the water treatment cost for human consumption. We will be able to measure it in the water quality and the restoration of the biodiversity. We will use a drone on a weekly basis to take arial pictures of the dam to build up a database to track the growth of the hyacinth and our impact of the harvesting. Our process will be upscaled until we reach a point where we can maintain the Water Quality, and biodiversity on the back of the pollution entering the dam on a yearly basis. 

Social and Economic Impact: 

The number of Direct and Indirect Green Jobs created. Restoration of Tourism, Property Market and Property Development Industries.

The pollution and the huge hyacinth infestation led to the restriction of water use eq. water sports, fishing, which has a negative impact on the Tourism industry, the property market and the property development industry around the dam. This has led to job losses. By restoring the ecology of the dam, we will indirectly restore the economy around the dam and this will lead to the creation of indirect jobs.  

Possible Negative Environmental Impact from our operation

HyaPOWER as a company is very much aware that our water resources are very sensitive ecosystem and with many depending on it for their lively hoods. Therefore, we are committed to eliminate any negative impact our operation may have on the environment and it’s people. It is important to note that HyaPOWER will be producing energy products which is based on an Anaerobic process, similar to the organic process in a cow’s stomach. It is not a petroleum base refinery process. No organic waste will be produced by the system, all matter exiting the main process will be reprocessed into some form of a by-product. Our process is based on ‘Negative Emissions Technologies’. In other words: The biomethane fuel we will be producing will also be the fuel that we use through our business. BioLNG colorless, odorless, non-corrosive, non-toxic and non-flammable liquid at -162°C.       

AIR POLLUTION:

No Diesel or Petrol will be used through our business. All the machines from the harvester, generators, compressors, delivery tracks and all support vehicles will be powered with BioLNG/CNG. The CO2 recovered from the upgrading process of the Biogas will be used in greenhouse as an aerosol fertilizer. In this way we will be able to create a negative carbon footprint. Our production facility will be an air-tight system to prevent and methane releases into the atmosphere

Water pollution:

No Diesel or Hydraulics will be used on our harvesters. All the systems and processes on the harvesters will be driven ether Electrically or Pneumatically. No fluid or solid waste will be produced or released back into the dam. The digested biomass exiting the anaerobic process called digestate is rich in nutrients and will be dewatered and palletized as an organic fertilizer. The process water exiting the system is also rich in nutrients and will be concentrated into a liquid fertilizer. The remaining water will be recycled back into the system. BioLNG is lighter than water therefore it will float on the water and at -162°C it will quickly evaporate without leaving any remains.

Noise pollution:

The harvester will be fitted with an ultralow noise power generation unit. This unit will not produce more than 65dB at a 10m distance during normal operation. The process plant will be powered by low noise CHP generator.  

Bad smells:

Our only source of feedstock will be biomass from the dam. Therefore, nothing from our process can smell worse than what come from the dam. The entire process will be a closed loop system. The BioLNG/Biomethane fuel and CO2 we will be producing is odorless. The H2S recovered from the biogas upgrading process smells like rotten eggs, but this will be converted to SO2 (a yellow powder) in an enclosed process and sold as a by-product.

Visual Impact:

No structure in the process plant will be higher than 12m and all the reactors and storage vessels will be painted dark green to melt into the surrounding environment. A line of trees will be planted around the perimeter of the process plant to further reduce the visual impact.

Danger to watersport activities:

No harvesting operation will be done on Sundays and public holiday. The harvester will avoid tourist hot spot unless requested to do so. The harvester will be fitted with yellow construction warning lights.

 

Fire and Explosions:

The health and safety of our people and the community will be out first priority. It is important to note that HyaPOWER will be producing energy products in the form of Biomethane which is based on an Anaerobic process, similar to the organic process in a cow’s stomach. It is not a petroleum base refinery process with high temperature and extreme pressures. None the less, our anaerobic process plant will be designed, build and operated in compliance with special legislation, regulations and all relevant industrial and safety standards to ensure that we limit any possible hazards. BioLNG in a liquid state non-flammable and non-explosive. The BioLNG vapor or biomethane in only explosive in a confined space with an air/fuel mixture between 5-15% and only when ignited with an electrical spark. Therefore, our production facility will be an open-air facility to allow for adequate ventilation.   

Conclusion:

Please feel free to contact us to discuss any issues that were not adequately addressed above, and we will be happy to work on a solution to eliminate any issues that may arise. At the end of the day our positive impact on the environment must far out way any negative impact we may have.
