Standardised yield assessments for industrial solar heat plants

Standardised yield assessments for industrial solar heat plants

The yield of solar process heat systems as simulated during feasibility studies has a decisive influence on the profitability of the respective investment. Therefore, simulation tools play an important role in the project development phase. Currently, however, project developers use a large number of simulation tools, whose results may differ …
Pathway to 100 % renewables: “Industry is a really hard-to-abate sector”

Pathway to 100 % renewables: “Industry is a really hard-to-abate sector”

“The world is burning more fossil fuels than ever. We need deep structural change,” REN21 Executive Director Rana Adib warned attendees at a panel discussion at last week’s Solar World Congress. “It is not enough anymore to look at the energy supply side – that is, the power sector – …
Tackling the complexity of urban-level energy simulations

Tackling the complexity of urban-level energy simulations

A special “Fall School” for PhD and advanced master’s students to enhance their knowledge of designing and implementing solar strategies in urban areas was offered by the IEA SHC Task 63 Solar Neighbourhood Planning in October. Dr. Caroline Hachem-Vermette from the University of Calgary, Canada, organised the course for 14 …
Germany supports solar thermal in energy systems with cogeneration

Germany supports solar thermal in energy systems with cogeneration

The use of solar district heating is rapidly gaining momentum in Germany. One reason is that the first projects which have received state support under the Innovative Combined Heat and Power Programme are close to completion. An example of a local energy supplier that has profited from this is municipal …
Future role of solar heat in IEA’s Net Zero Roadmap

Future role of solar heat in IEA’s Net Zero Roadmap

In May the International Energy Agency challenged policy makers with a 224-page report titled Net Zero by 2050: a Roadmap for the Global Energy Sector including 400 milestones that governments have to realise to achieve the 1.5 °C target. Whereas for solar heat in buildings fairly progressive targets are set …
Bulgaria torn between support for coal and decarbonisation aims

Bulgaria torn between support for coal and decarbonisation aims

In Bulgaria’s capital Sofia, 1,698 kilometres from Brussels as the crow flies, politicians remain wary of the EU’s Green Deal plans, reports our long-time Sofia correspondent Frank Stier. A sun-rich country bordering on the Black Sea, Bulgaria became a member of the EU in 2007. But while 18 % of …
Low-temperature heat networks key to positive energy districts

Low-temperature heat networks key to positive energy districts

In Europe, positive energy districts are still in their early stages. But initial pilot projects have shown that low-temperature district heating grids play a central role in the design of these smart districts. So far, however, there has been little policy support for PEDs, noted the experts who attended the …
"Renewable heat generation should be privileged in the Building Regulations §35"

“Renewable heat generation should be privileged in the Building Regulations §35”

There is a lack of land available in Germany for solar district heating systems due to the complexity of the land-use plan procedure. Some local mayors who are active for climate protection have already given up on the idea of solar heating in their communities because the search for suitable …
“We have an increasing number of new large projects in the pipeline”

“We have an increasing number of new large projects in the pipeline”

The Finnish turnkey solar heat system provider Savosolar held an extraordinary general shareholder meeting on 1 October to discuss rights issues of approximately EUR 5.4 to 6.4 million with three warrant programmes. The assembly authorised  Savosolar’s Board of Directors to decide on issuance of shares, options and other rights up …
“Energy taxes and emission trading systems complement each other”

“Energy taxes and emission trading systems complement each other”

Internalizing the costs of pollution into energy prices – this has been one of the key objectives of Climate Action Network (CAN) Europe for many years. In this context, two documents from the new Fit for 55 package are of major importance: the revision of the Energy Taxation Directive (ETD) and the …
10 MW solar plant heats air for malting plant in France

10 MW solar plant heats air for malting plant in France

A 10 MW flagship solar heat project was inaugurated on 20 September 2021 in Issoudun, Southern France, making it the largest solar industrial heat plant in France and the second largest in Europe. The 14,252 m2 solar collector fields now supply 10 % of the total heat requirement of the …
China’s future role in the IEA SHC Programme

China’s future role in the IEA SHC Programme

The Chinese solar thermal market shows a varied picture of demand. While subsectors such as solar space heating are booming, total market volume continues to decline. Solarthermalworld.org spoke with two professors at the China Academy of Building Research, He Tao (see above) and Ruicheng Zheng (see below), about the drivers …
