For our industrial clients we scrutinize the energy consumption and the business processes, to analyze which (renewable) solutions are the best to integrate and in which manner. The goal being to increase the profitability of your company, and to guarantee a sustainable business management in the long run.
Essenga investigates the technical feasibility of the project, as well as the financial rentability for the long term. As such we develop engineering solutions in which we enhance the various green energy sources, deployed in one project, to reach a maximum ROI. We gladly research which of the techniques below match your company best, and what their possible return would be. We provide advice, installations and maintenance, as well as complete project management.
Essenga designs made-to-measure industrial automation solutions that are user-friendly and mainly based on renewable energy. If desired, we guide your project from engineering to installation. Options include designing new projects as well as adapting existing installations.
The kinetic energy produced by wind can be transformed into electricity by means of wind energy convectors. It is a very environmentally beneficial alternative as wind turbines provide electricity without producing polluting emissions. On the other hand, possible noise disturbance and shadow caused by the reversing blades are adverse effects.
Although the tax concession for solar panels has been abolished, investing in solar energy remains a sensible and profitable choice. The solar panels themselves have been heavily reduced in price, which allows to them to still compete with other green energy sources. Depending on your electricity consumption and profile, you will recover your investment after a period of 8 to 9 years. Also, the sun is an inexhaustible energy source and the solar panels are recyclable. So you can consider this to be a very environmental friendly alternative!
A heat pump withdraws warmth from the soil, water of the air. It then heats this under pressure, and pumps the heat into the central heating system or warms water, by means of a special fluid. This environmentally friendly alternative for a classis heating system will only yield return when used in well insulated areas. The results are brilliant when used in combination with e.g. floor radiation heating in a properly insulated building. A heat pump can also provide warm water for sanitary installations or provide cooling, depending on the installation.
Combined heat and power system (CHP)
When it comes to energy provision, most people think of electricity and forget about thermal energy (heat). Most of the time electricity and heat are generated by different installations. With a combined heat and power system (CHP) you can generate both at the same time. This way you will use an average of 15% less of fuels to generate the same amount of heating and electricity, which substantially reduces you energy cost. When we run the combined heat and power system on renewable energy sources, you can even lower you energy cost further. A combined heat and power system can either be a conventional gas combusting engine or a gas turbine.
Organic rankine cycle (ORC)
With many industrial processes a lot of energy is lost in the chimney. Heat a a higher temperature is not used because it helps the production process. This ‘lost’ heat can however be used to generate electricity by means of an ORC-installation. An organic rankine cycle or ORC is a rankine process with an organic solvent such as propane, isobutene, isoptane or ammonia instead of steam. In many cases a turbine is used. Because an organic solvent has a lower boiling point than water, the ORC makes it possible to generate energy from a lower temperature up to even a 100°C. This cycle is very suitable for utilizing residual heat. Utilizing landfill gas (which is unsuitable for a combustion engine because of the changing composition), geothermal energy and solar energy concentrated by parabolic mirrors is also a possibility.
When waste and vegetable material (biomass) are burned, energy is released. This energy is CO² neutral: the burning process does not release more CO² than what was ingested by the biomass in the first place. When biomass is properly utilized, it is one of the most cost effective sources of renewable energy. It is also a pretty much inexhaustible source and a highly environmentally friendly solution because it allows us to substantially reduce the refuse dump and convert it into usable energy.
Bio fermentaiton also produces sustainable energy. The big advantage of energy production by means of bio gass is that for this process we do not depend on the weather conditions, which is the case with solar energy and wind energy. A lot of companies have already chosen to utilize bio fermentation. It is an environmentally friendly solution and a technology that is easy to implement.
