The German Federal Ministry for Economic Affairs and Energy (BMWi) is expanding its funding for fuel cell heating systems. With immediate effect, you can apply to KfW for attractive subsidies for the installation of fuel cell heating systems in both all residential and non-residential buildings. Private individuals, freelancers, small and medium-sized enterprises (including contractors) as well as municipal and non-profit organisations are eligible to apply.
The subsidy is available for fuel cell heating systems with an electrical output of up to 5 kW that are installed either as part of a refurbishment or a new build. Depending on the electrical output, a subsidy of up to 28,200 euros per installed fuel cell is possible.
The aim of extending the funding is to establish the pioneering fuel cell technology for supplying electricity and heat in buildings on a broad market. Fuel cell heating systems are significantly more efficient than conventional combined heat and power systems. The natural gas or biogas used is utilised much more efficiently, which also leads to lower CO2 emissions.
Grant funding for fuel cell heating systems is part of the German government's "Energy Efficiency Incentive Programme". It supplements the existing KfW programmes for energy-efficient construction and renovation. Since the programme was launched in August 2016, the installation of over 900 fuel cell heating systems, primarily in detached and semi-detached houses, has been supported with grants of around 13 million euros.
A village is being built in the Netherlands that will be completely self-sufficient - from electricity production to food supply. The Utopia website shows what it will look like: Utopia.de

In its 2.10.2017 published opinion the German Advisory Council on the Environment calls on the incoming German government to initiate the coal phase-out without delay. The upcoming legislative period offers the last chance to set the course for an appropriate implementation of the Paris climate goals in Germany.
"Germany must reduce power generation from coal as quickly as possible and end it in the medium term, otherwise the climate targets in Germany cannot be achieved. The structurally compatible coal phase-out should therefore be initiated immediately. The last power plant must be taken off the grid in 20 years at the latest," explains Prof. Claudia Kemfert.
The basis of the coal phase-out should be a budget of the total amount of greenhouse gases that may still be emitted by coal-fired power plants until their final shutdown. This amount should be fixed by law. "From a scientific point of view, the remaining emissions budget for coal-fired power generation in Germany should be 2,000 megatonnes of CO2 Prof. Wolfgang Lucht specifies.
In its report, the SRU proposes a phase-out in three phases: The most emission-intensive power plants should be taken off the grid by 2020. On this basis, more modern plants could continue to operate at reduced capacity until about 2030 to ensure security of supply and to preserve jobs. In the 2030s, these power plants should then also be decommissioned. The federal government must now define the framework for this.
Climate protection and the shaping of structural change must go hand in hand. A long-term and structured phase-out path offers those affected planning security and can ensure that the burden is shared as fairly as possible. The phase-out path and its structural policy support should therefore be discussed in a commission together with the affected regions, companies, trade unions and environmental protection associations.
The German Advisory Council on the Environment (SRU) has been advising the German government on environmental policy issues for almost 45 years. The Council's composition of seven professors from different disciplines ensures a scientifically independent and comprehensive assessment, both from a scientific and technical perspective as well as from an economic, legal and health science perspective.
The Council currently consists of the following members:
Prof. Dr Claudia Hornberg (Chair), Bielefeld University
Prof. Dr Manfred Niekisch (Vice-Chairman), Goethe University and Frankfurt Zoological Garden
Prof. Dr. Christian Calliess, Free University of Berlin
Prof. Dr. Claudia Kemfert, Hertie School of Governance and German Institute for Economic Research
Prof. Dr Wolfgang Lucht, Humboldt University Berlin and Potsdam Institute for Climate Impact Research
Prof. Dr.-Ing. Lamia Messari-Becker, University of Siegen
Prof. Dr.-Ing. Vera Susanne Rotter, Technical University Berlin
