Virtually carbon-neutral, Renewable Natural Gas (RNG) is therefore continuously available and can make a significant contribution to climate protection and the sustainable supply of energy.
As a carbon-neutral fuel, bio CNG (compressed natural gas) has obvious advantages. In the transport sector alone, switching to RNG from fossil fuels could cut CO2 emissions by up to 97 percent. In Germany, however, progress in developing the necessary infrastructure has been sluggish to date. We’ve joined forces with Munich-based BAUER Kompressoren GmbH to make a difference here: this long-term partnership means EnviTec is able to offer a complete package from biodegradable waste to the CNG pump from a single source. The system components – high-pressure compressors, gas buffer tanks and CNG pumps – are supplied by BAUER and installed in containers by EnviTec’s engineers. Depending on customer requirements, these are then integrated into the overall biogas plant and gas upgrading system. Once complete, HGVs, cars and buses can all then be fuelled. In China, EnviTec used this technology to acquire new customers such as Shandong Minhe Biological Scitech Co. Ltd. The CNG plant compresses the RNG from around 13.5 bar to 200 bar in a CNG tube trailer for delivery to a CNG filling station.
To boost the share of heat from renewable sources to 14 percent by 2020, using RNG in combined heat and power (cogeneration) plant is one of the most sustainable technologies currently available. Especially in cases where other kinds of renewable energy technologies or measures to reduce energy requirements are not deployable to the extent needed for structural reasons, the use of RNG in heating-only applications is a useful alternative.
There are several usage models for RNG-based heating. Typical consumers are the plant operator’s own property or business premises, housing complexes or public facilities fed via heating grids, as well as horticultural, commercial and manufacturing companies. All of this makes RNG an inexpensive and efficient renewable energy option on the heating market.
A reliable electricity supply requires a balance between electricity production and demand at all times. Accordingly, the load at any point in time must be met by a guaranteed level of (power generation) performance. As power generation from fossil fuels and nuclear power plants starts to be wound down, alternative solutions to provide this level of performance are required. Flexible power generation plants are a viable option here: these can respond quickly to changes in electricity generation from the fluctuating feed-in of renewable energy sources and handle the tasks required to secure the energy supply. The use of RNG enables the provisioning of the relevant system services on the basis of renewable energy sources and so reduces the need for fossil-based power plants.
…and we’re thinking even further ahead:
The CO2 generated during RNG production can be reused and liquefied. Ultrapure carbon dioxide offers an interesting additional source of revenue for plant operators, and can be utilised in a wide variety of industries (such as the food industry, in horticulture, for firefighting or in refrigeration plants).
