European Copper Institute (ECI) contributes to political debate, directly and through stakeholder platforms, sharing its expertise of copper-based products and technical building services and their contribution to the Commission goal of a carbon-neutral building stock. ECI has a considerable knowledge base and multidisciplinary expertise in technology, chemical policy and life cycle relating to copper and its applications. It also has established outreach channels aimed at supporting its advocacy towards the EU institutions.

Solarthermalworld.org was initiated by ECI in 2008 with the aim of providing stakeholders from research, public and private sector all around the globe with first-class information about solar heating and cooling to stimulate market growth. The ECI has supported the hosting of the website as well as the content gathering continuously since 2008.

concentrating solar technologies CST

Challenging short completion deadline

Fifty-one solar heat projects totalling 61 MW were awarded funding in Spain in the first round of the subsidy scheme Thermal Energy Production. The majority of these projects use concentrating solar technologies. This is a great step forward in a country where currently concentrating solar heat plants with a total …
Call for renewable heat projects

EU fund allocates EUR 108 million for C&I renewable heat projects

The first call for renewable heat projects for the industry and service sectors in Spain resulted in awarded grants of EUR 108 million. This budget will be used to support 51 solar heat projects totalling 62 MW. Within this funding line Thermal Energy Production beneficiaries receive non-repayable grants co-financed by …
Unfavourable stop and go policy in England

Unfavourable stop and go policy in England

The Green Homes Grant scheme in England “underperformed badly”. The Public Accounts Committee came to this conclusion when reporting that only about 47,500 families upgraded their homes out of the 600,000 originally envisaged and the scheme caused GBP 50 million of administration costs – more than GBP 1,000 per home …

Cities united for climate action

Cities drive climate action – that much is clear when looking at the numbers presented in last November’s 2021 Global Covenant of Mayors Impact Report. The signatories to the covenant announced a total of 222,034 actions, committing themselves to a reduction of 76 gigatons of CO2 by 2050, an amount …

Greenpeace Bulgaria campaigns for sunny future of heating

Greenpeace Bulgaria is actively campaigning to promote solar energy for heating purposes. The Bulgarian branch of the global environmental organisation has not only published promotional material but Greenpeace also donated two solar laboratories to schools to educate students about a decarbonised economy. At the beginning of this school year in …
Solar heat to save Switzerland several CHF 100 million a year

Solar heat to save Switzerland several CHF 100 million a year

A new roadmap called SolTherm2050 shows how much of a role solar heat combined with thermal storage could play in Switzerland in 2050. Using the Swiss EnergyScope tool, the developers of the roadmap simulated a variety of scenarios with and without solar thermal. In addition, over half of their 117-page …
Lessons learned from three years promoting SDH in the Western Balkans

Lessons learned from three years promoting SDH in the Western Balkans

The interest in solar district heating has increased significantly in Serbia since the European Bank for Reconstruction and Development (EBRD) started to finance prefeasibility studies for SDH plants in January 2019. Furthermore, Serbia adopted a Renewable Energy Law in April 2021 which includes an ambitious mechanism to support the implementation of renewable …
Feasibility studies on 13 solar heat plants underway in Austria

Feasibility studies on 13 solar heat plants underway in Austria

Solar district heating has turned around the steadily declining solar thermal market in Austria. As reported at the Austria Solar organisation’s annual meeting in December, solar heat was in high demand all over the country last year. Of particular note was the second quarter, in which capacity additions made a …
Molten salt: suitable heat-transfer fluid for concentrating collector fields

Molten salt: suitable heat-transfer fluid for concentrating collector fields

In a parabolic trough collector demo plant run by the German Aerospace Center (DLR) in Évora, Portugal, molten salt is used as a heat-transfer fluid instead of thermal oil. The advantage of molten salt is its stability at higher temperatures. Whereas thermal oil cracks at above 400 °C, molten nitrate …
