World's largest solar heating plant in China

Solarserver reports on the world's largest solar heating plant, which has been in operation in China since 2016. It consists of parabolic trough collectors.

On the roof of a XuChen factory hall next to the company headquarters, there are 22,000 m2 collector area, a further 71,000 m2 collector area are implemented as ground-mounted systems. Together they deliver an output of 65 MWth. With concentrating collectors, it would thus be the largest solar heating plant of its kind. An even larger one is the Danish Silkeborg plant (110 MWth)which, however, is equipped with a different collector technology.

By way of comparison, the largest German solar thermal plant supplying a housing estate, neighbourhood or district currently has just 14,800 m².


PV obligation on non-residential buildings in Baden-Württemberg

Environment Minister Franz Untersteller reacted with relief to the agreement reached yesterday by the coalition on the amendment of the Climate Protection Act. The law is to be passed by the state parliament before the summer break and will then replace the previous climate protection law from 2013.


European solar research and industry calls for "Solar Europe Now

Brussels/Fribourg, 5 May 2020 - A new alliance, "Solar Europe Now", officially launched on 5 May, calls for the recognition of solar energy as a key technology for the objectives of the European Green Deal. The new alliance, which currently includes more than 90 stakeholders from across the European solar value chain, is concerned that the current presentation of the Green Deal does not take enough account of the photovoltaic sector.


Berlin Senate adopts "Solarcity Master Plan

From the March 10, 2020 meeting of the Senate:

The Senate today adopted a comprehensive catalogue of measures to accelerate the expansion of solar energy in Berlin, based on a proposal by Ramona Pop, Senator for Economic Affairs, Energy and Industry.

Senator Pop: "The potential study for the Solarcity master plan has shown that we can harvest 25 percent of electricity generation with solar energy from the roofs of Berlin. To achieve this, we must accelerate the expansion of solar energy in the city. It is necessary for the federal government to finally improve the legal framework for solar energy in cities. Nevertheless, we want to actively use the existing leeway at the state level. With the Solarcity Master Plan, we will expand information and advice, set incentives and also examine regulatory instruments. The implementation of the Solarcity Master Plan is a joint task for the Senate, but also for all Berlin stakeholders from business and society."


The heat turnaround begins in the district

One of the Herculean tasks to achieve the climate targets is to radically reduce CO2 emissions from the heat supply. A group of researchers led by the Institute for Ecological Economy Research (IÖW) shows how cities can turn away from coal, oil and gas in a socially acceptable way. The project "Urban Heat Turnaround" investigated possible contributions from renewable energies and local heat sources in Berlin's urban neighbourhoods. "Waste heat from businesses, heat from waste water or geothermal energy have hardly been used so far.


Hamburg's new climate plan and new climate protection law

Senate adopts concrete measures for the next ten years and sets new CO2-targets for 2030 and 2050

December 3, 2019. Today, the Senate has set two decisive courses to achieve Hamburg's climate goals with an update of its climate plan and a new climate protection law. CO2 emissions are to fall by 55 percent by 2030, and Hamburg is to become climate-neutral by 2050. The climate plan describes the responsibility and the respective CO2 reduction targets in the sectors "transport", "private households", "trade, services, commerce" and "industry". It contains a large number of concrete measures which are to lead to the necessary reduction of CO2 emissions by 2030. The draft of the new climate protection law creates a binding legal framework for this.

8 percent less solar thermal in 2018

According to the annual balance sheet of the Federal Association of the German Heating Industry (BDH) presented today, the German market for solar thermal systems has shrunk further by 8 percent to 573,500 square meters of collector area.


Rhine-Hunsrück district is energy municipality of the decade

Yesterday, the Agency for Renewable Energies awarded the Rhine-Hunsrück district as Energy Municipality of the Decade / Environment and Energy Minister Ulrike Höfken congratulates warmly on this award. Yesterday, the Agency for Renewable Energies awarded the Rhine-Hunsrück district in Kassel as "Energy Municipality of the Decade". "Climate change is clearly noticeable in Rhineland-Palatinate, as currently [...]


Heat turnaround in Gimbweiler

The state of Rhineland-Palatinate is providing funding of 150,000 euros for a local heating network in Gimbweiler, which is to be supplied in future by means of a solar thermal open-space system and a woodchip system.


Conference presents compass for future-oriented energy research

The successful implementation of the energy transition requires a variety of technologies that solve different tasks in the energy system. Missing components must be supplemented and optimization processes implemented. Technological innovations, supported by social innovations, play a central role in this. Now, several projects are systematically investigating the potentials of the individual energy technologies and the innovation needs [...]


New solar roof register in Bonn goes online today

BN - Is the roof of my house or company building suitable for a photovoltaic system or a solar thermal system? This question can now be answered quickly and conveniently online with the help of the new solar roof cadastre of the city of Bonn. In a building-specific map display, a colored marking indicates whether and to what extent [...]


Video (2017) Möckernkiez in Berlin celebrates topping-out ceremony


14:16 min, from 15.08.2017, compilation of the event

"A year ago, Germany's largest cooperative building project was on the brink of collapse; on Thursday, the Möckernkiez is celebrating its topping-out ceremony. Just under a third of the 470 apartments at Gleisdreieck are to be ready by the beginning of the year - much later and more expensive than planned."

All apartments are scheduled to be ready for occupancy by July 1, 2018.

Declining costs of renewables drive global energy transition

According to Dr. Axel Berg, chairman of the board of the German section of EUROSOLAR, neither ambitious climate protection goals nor increased ecological awareness are the drivers of the energy turnaround, but rather "the exponential cost degression in renewable energy technologies, the technical innovations in storage technologies and a high level of interest from the industrial economy." In his detailed [...]
