What is Hemp Biomass CHP?
Hemp absorbes an amazing 1.37 tonnes of CO2 per 1 tonne of hemp stem grown!
Why is Hemp Biomass Heat and power good for the environment?
The use of biomass is classed as being ‘Carbon Neutral’ and therefore do not contribute to Global Warming. As trees grow, they absorb carbon dioxide from the atmosphere during photosynthesis. When the wood is subsequently burnt, that same amount of Carbon is released back into the atmosphere and thus there is no net increase in Carbon and no impact on the environment. Compare this with the burning of fossil fuels such as oil and gas where the Carbon has been locked away for millions of years – until we burn it and release it.
Hemp can be classed as carbon negative dependant of the processes, as it absorbs more carbon in weight than it produces as stem! With this huge advantage and that biomass CHP produces a far lower carbon emission than traditional heat and power, we are out to show that Hemp Biomass CHP can actually produce carbon negative energy!
One hectare of industrial hemp can absorb 22 tonnes of CO2 per hectare. It is possible to grow to 2 crops per year so absorption is doubled. Hemp's rapid growth (grows to 4 metres in 100 days) makes it one of the fastest CO2-to-biomass conversion tools available, more efficient than agro-forestry. Hemp absorbes an amazing 1.37 tonnes of CO2 per 1 tonne of hemp stem grown!
Biomass is also a renewable energy. Trees are specifically grown to produce biomass fuel in sustainable forests that are constantly replanted as trees are felled. Hemp can produce much larger quantities of biomass than the fastest growing trees. The fuel can be grown in many parts of the world and thus we are not dependant on the traditional fossil fuel sources. The rest of the plant has numerous end uses making it a very good all-round crop.
Even the ash makes a great fertilizer for the garden.
Installing a Biomass CHP system will dramatically improve the Environmental impact of your premises, reducing your use of fossil fuels and reducing your carbon footprint. This is a very valuable public relations story for your customers who will be increasingly aware of global warming and the need to work with companies with impressive Green credentials.
What is CHP?
Combined heat and power (CHP) is a process that provides both heat and power on site in one single, highly efficient process.
CHP generates electricity and as a by-product of the generation process, heat is produced. This heat can be used on site while using the power generated. In contrast, our traditional coal and gas power stations can loose up to two thirds of the heat produced. By generating the heat and power on site, CHP systems can acheive in excess of 80% efficeincy.
Hemp Wood Biomass is fed into the system similar to a normal biomass boiler. Instead of feeding it Oxygen to burn the fuel, it is heated in an environment that has no oxygen present. At around 700 degrees Celsius, all the gases from the hemp are extracted and instead of being burnt, run through cooling coils and filters that produce a synthesis gas or Syngas. The gas is then fed to an engine that runs on the gas. Connected to the engine is a generator to provide electricity and the heat produced by the engine, instead of going to a radiator, can be fed into a heating system.
By using biomass, a carbon neutral fuel to power the CHP systems, substantial reductions in CO2 emmissions can be achieved
With the government’s commitment to reducing carbon emissions, several schemes have been initiated to help bring renewable technology to the market. Most renewable technologies take advantage of one or two of the tariffs to help pay back the cost on the system. Biomass CHP can take advantage of all the schemes due to generating both renewable heat and power. The schemes are as follows:
The Renewable Heat Incentive
This rewards people for generating heat from a renewable heat source such as biomass. A heat meter is placed on the system that records generation and the government’s scheme pays the owner of the equipment a certain tariff depending on the technology and size. Biomass boiler installations over the last 5 years have boomed with the introduction of this tariff.
Low Carbon, Low Cost Electricity
By generating your own power on site, there is a huge drop in carbon emissions due to the advantage of having no transmission losses getting thre power to your home. This also makes it cheaper than grid costs.
