Big Solar Germany: solar heat at record-low 36 EUR/MWh

Dear Solarthermalworld.org Reader, 

 

Operators of several gas-driven combined cycle power plants have notified the German Federal Network Agency of their systems’ final shutdown. These plants are no longer economically viable, as they have been running ever fewer hours because of a high proportion of cost-effective renewable grid electricity. Their shutdown will create a shortage of supply in district heating networks providing thermal energy to German municipalities. Utility-scale solar thermal plants equipped with seasonal storage could help close the gap at attractive heat prices of around 36 EUR/MWh, said Christian Holter, Managing Director of Austrian turnkey system supplier S.O.L.I.D., which has carried out feasibility studies on behalf of several European cities.

India: Financial support for concentrating solar systems extended until 2020
by Jaideep Malaviya

The “order” published by the Indian Ministry of New and Renewable Energy on 26 February 2018 put an end to the uncertainty which had pervaded the industry. In the 2-page document, the ministry pledged to continue its investment subsidy programme for concentrating solar thermal systems. The target until March 2020 is 90,000 m² of collector area.

Tibet´s highly subsidised solar heating market
by Bärbel Epp
 

Tibet is currently in the focus of the Chinese central government’s efforts to improve the heating situation of the population. The lack of space heating in many buildings in the region has prompted China’s government to support the installation of solar district heating systems. Chinese parabolic trough collector manufacturer Vicot Solar Technology has signed a contract with the local government to install a solar district heating system with 18,000 m². The photo, taken in November 2017, shows one-third of the field’s substructure.

Solar thermal and biomass – a winning solution for district heating
by Riccardo Battisti

Biomass may be cheap and carbon-neutral, but a solar upgrade of biomass-fired district heating could further improve efficiency and reduce local emissions. For example, solar heat helps avoid having to start up and shut down wood-chip boilers or operate them at partial load. It can even replace backup fossil fuel systems, which provide district heating networks with energy in summer.

World’s largest flat plate collector manufacturers in 2017
by Bärbel Epp
 

The 2017 ranking of the world’s largest flat plate collector producers clearly shows the market dominance of Chinese companies. Even second-ranked Greenonetec, an Austrian collector manufacturer, is now majority-owned by the Chinese-based Haier Group. The corporation acquired 51 % of the manufacturer’s shares on 18 May 2017. The largest European flat plate collector producer was heating technology supplier Bosch Thermotechnik, although it remained at a certain distance from the top four.

Molten salt storage 33 times cheaper than lithium-ion batteries
by Riccardo Battisti

Cost-effective energy storage is key to transitioning to a low-carbon society. A popular storage method for high-temperature thermal applications is a molten salt tank. Fact sheets created by the German Energy Storage Association show that molten salt tanks are around 33 times less expensive than electric batteries when it comes to storing a kilowatt-hour in them.
