We would like to inform you about the congress “Eco Innovations from Biomass” in Papenburg, Germany, from 28 to 29 June 2017. As main topics of the congress, the prospects of bioeconomy and the relevance of biomass in the national and international context will be discussed. Furthermore, regional strategies for action, good practice bottom-up concepts and latest knowledge of research centers and industry concerning bio refining and Biobased products will be presented.
On the evening of 29 June, the 6th Lower Saxony Algae Round Table will take place. A separated registration is required.
We are looking forward to meeting you at the Eco Innovation Congress!
The aim of the congress is to provide an international platform for the exchange of knowledge about the bio-economy in the non-food sector and to discuss strategies for an efficient material utilization and energy recovery from biomass and residues according to the concept of a closed substance cycle. Presentations will be made on successful bottom-up concepts and current findings from research and practice concerning new green routes, biomaterials, biorefining, procedures for recovering nutrients and algae production as well as paludicultures. Companies will present »eco-innovative« product developments.
Companies, knowledge and research institutes are kindly invited to submit posters or to participate as exhibitors.
In order to achieve the global and national climate protection targets by 2050 special efforts are required by all sectors of the economy. Sustainable and eco-friendly products and procedures on the basis of biomass and residues play an essential role in this context. The bio-economy in the non-food sector promotes these innovative developments since they provide remarkable opportunities for companies of different industries, such as new products and services but also new customers and markets. In addition to the presentations there will be poster exhibitions and opportunities for networking with different discussion forums.
The congress is organised by 3N Kompetenzzentrum Niedersachsen Netzwerk Nachwachsende Rohstoffe und Bioökonomie e.V. in cooperation with the Lower Saxony Chamber of Agriculture.More info
Bonaire (pop. 14,500), a small island off the coast of Venezuela, is famous for its beautiful marine reefs, which are visited by 70,000 tourists every year. What many of the tourists don’t realize is that the majority of the electricity powering their needs comes from renewable energy. Yet for the residents of Bonaire, the switch from fossil-fueled to renewable energy systems has made a world of difference.
Like many Caribbean islands, Bonaire originally relied on diesel fuel to generate electricity for residents, with a peak demand of 11 MW. This fuel had to be shipped in from other nations, resulting in high electricity prices for Bonaire residents, along with uncertainty about when and how much prices might increase with changing fuel costs.
In 2004, everything changed when a fire destroyed the existing diesel power plant. Although tragic, the situation provided an opportunity for Bonaire to consider what kind of new electricity system to build. Temporary diesel generators were rented to provide power for the short term. Meanwhile, the government and local utility began working together to create a plan that would allow Bonaire to reach a goal of generating 100 percent of its electricity from renewable sources.
The result is a transformed electricity system on Bonaire. The island is now home to 12 wind turbines with a total of 11 MW of wind power capacity, which contribute up to 90 percent of the island’s electricity at times of peak wind, and 40–45 percent of its annual electricity on average. Battery storage (6 MWh) is included in order to take advantage of available power in times of excess wind, and provide that stored electricity in times of low wind. The battery also boosts the reliability of the overall system—it is capable of providing 3 MW for over two minutes, allowing time for additional generation to be started when there is a sudden drop in wind.
The Bonaire system also includes 14 MW of diesel generation, five total generators, which provide the necessary power to meet the load when there is not enough wind power available. The generators are equipped to run on both traditional diesel as well as biodiesel. The next steps in the island’s energy transformation involve using local algae resources, grown in the large salt flats on the island, to create biofuel, which can then be used in the existing generators. This will allow Bonaire to operate a 100 percent renewable electricity system—with on average 40–45 percent from wind and 55–60 percent from biodiesel.
The new electricity system led to more reliable electricity, more employment opportunities, reduced dependence on oil (and its fluctuating prices), and a reduction in electricity bills. Bonaire residents currently pay $0.22/kWh for electricity, much lower than prices on other nearby Caribbean islands, which are often $0.36/kWh or above. When oil prices spiked in 2008, while Bonaire was still using temporary diesel generators before making its transition to renewables, electricity prices on the island reached $0.50/kWh. The new electricity system also created jobs for the construction and ongoing operation of the wind farm, and for research and development of algae production capabilities and conversion to biofuel. Additional employment opportunities will be created for continuing algae production and operation of the biodiesel plant.
The success of the updated electricity system on Bonaire provides an important example to other nearby islands of the opportunity to achieve high levels of renewable energy penetration.
Two aspects unique to Bonaire’s situation may have contributed to the decision to switch to a 100 percent renewable electricity system. One driver may have been Bonaire’s status as a special municipality within the Kingdom of the Netherlands. This provides a connection with the Netherlands and Europe in general, where many countries have incorporated large amounts of wind and other renewable sources of electricity. Nearby Aruba, also a Dutch Caribbean island, has a wind farm as well, which provides up to 20 percent of the island’s electricity. There may be a common theme of islands with ties to European countries moving to renewables more quickly than others. In the case of Bonaire, the consortium that is developing the project, Ecopower Bonaire BV, is made up of Dutch and German companies.
Secondly, Bonaire’s government and local electricity provider were presented with an opportunity to build a new renewable electricity system since they needed to replace the plant that was damaged. Many other Caribbean islands still have existing diesel resources that are not at the end of their lifetime. These existing generators may remain a part of the electricity system, especially as renewables are incrementally added to the system, and may even remain as backup power for a transformed system that operates mostly with renewables. However, if some or all of the existing diesel resources on an island are completely shut down before the end of their available lifetime, that island will need to consider the sunk costs involved and incorporate that into their overall energy transformation plan.
RMI and Carbon War Room’s ongoing Ten Island Challenge works with Caribbean islands to utilize their local renewable resource potential to transform electricity systems and provide a renewable, reliable, secure, and affordable energy supply for their citizens. One of the participating islands is Aruba, which neighbors Bonaire and forms part of the ABC islands in the Netherlands Antilles, along with Curacao. Although the shift to renewables on Bonaire is not part of the Ten Island Challenge, RMI and CWR’s ongoing work in the area will strive to spread the success that Bonaire has achieved to the rest of the region, so that more Caribbean islands can take advantage of efficient and renewable electricity systems.
