Lithuania: Can Solar Thermal Beat Low Biomass Heat Prices?

Submitted by Baerbel Epp on August 14, 2017
Lithuania District HeatingWith biomass prices on the rise, solar district heating could become profitable in Lithuania. But without investment grants, payback periods were still too long, it said in the conclusion of a 2015 SDH market study by LEI, the Lithuanian Energy Institute (see the attached document in Lithuanian). The photo shows the country’s first SDH system set up in 2011. Installed on the roof of the boiler house, it preheats water for a wood chip boiler in the district heating station of Dūkštas, a town in eastern Lithuania. The demonstration unit with 82 m² of vacuum tube collectors received funding from international organisations.

Denmark: Concentrating Solar Collectors for District Heat in Northern Europe

Submitted by Baerbel Epp on August 11, 2017
BronderslevBrønderslev, a Danish municipality with a population of 12,500, is setting up a multi-purpose renewable heat plant for their district heating network. So far, local utility Brønderslev Forsyning has been operating seven gas-fired combined heat and power (CHP) plants and two gas boilers to produce 130 GWh of heat each year. In the future, most of the yearly district heating demand is planned to be met by a new Organic Rankine Cycle (ORC) unit which receives its energy from two wood chip boilers with 10 MW each and from a 16.6 MWth parabolic trough collector field with a mirror area of 27,000 m².

Austria: How to De-Risk Renewable Investments in Industry

Submitted by Baerbel Epp on August 9, 2017
Results World Map SurveyTwo-thirds of the 71 companies listed on the World Map of Solar Process Heat Specialists 2017 agreed that achieving bankability for solar process heat projects required huge efforts to be made. They said that key barriers to implementation were a lack of technical expertise in risk assessment at financial institutions and the relatively small investment amounts in individual projects. To rectify this situation, EU project TrustEE is aiming to combine several of industry’s energy efficiency and renewable energy (EE+RE) investment projects into one package to be offered to pension funds and assurance companies. Important financial terms can be found in the glossary at the bottom of this article.

ESTIF Rebranding: “We are solar, we are heat, we are Europe”

Submitted by Baerbel Epp on August 7, 2017
Robin WellingThe European Solar Thermal Industry Federation (ESTIF) has recently changed its name to Solar Heat Europe and developed a new corporate identity. It represents the interests of the solar thermal sector at EU institutions and is home to around 50 European solar thermal manufacturers, national industry associations, research institutes and service providers. Solar Heat Europe’s headquarters are in Brussels, where a team of four strives to advance solar heat solutions. Solarthermalworld.org spoke with President Robin Welling about the purpose of the rebranding effort. Welling is Managing Director of Austrian collector manufacturer and system supplier Tisun and has been President of ESTIF since 2010.

Germany: Tool to Calculate Solar Feed into District Heating Network

Submitted by Baerbel Epp on August 1, 2017
Map District Heating in GermanyInterest in solar district heating is growing in Germany. A map by German research organisation Solites shows the systems currently in operation to be 23 totalling 49,600 m² of collector area (34.7 MWth). Last year saw the addition of four installations with a combined area of 12,921 m²; one of them was Germany’s first record-size solar district heating plant in 11 years, in Senftenberg. Solites has now developed a tool to calculate the yield of SDH plants. Called SCFW 2.0 (ScenoCalc Fernwärme 2.0), it is available as a free download at www.scfw.de and is hoped to increase transparency by improving the comparability of solar district heating plants and solutions.

Solar Thermal Shows Highest Energy Yield Per Square Metre

Submitted by Baerbel Epp on July 31, 2017
Area Yield ComparisonThe annual energy yield per square metre is much higher for solar collectors than for other renewable technologies, as the figure on the left shows. Compared to PV, solar collectors produce, on average, three times as many kilowatt-hours. Compared to biomass or bioethanol, output is in average as much as 43 times their yield. The chart shows end energy production and compares directly thermal and electric kilowatt-hours. The grey part of each bar marks the deviation in yield based on different estimates. The absolute values can be found in a table at the bottom of this article.

IEA-RETD: Lessons Learned from 21 Renewable Projects in Industry

Submitted by Baerbel Epp on July 28, 2017
Case Study MapThree years after the International Renewable Energy Agency underlined in its June 2014 Renewable Energy in Manufacturing study the great potential for using renewables in industry, the International Energy Agency has published a comprehensive report on the same topic. It is titled Fostering renewable energy integration in the industry and consists of several documents divided into two parts: a review of 21 case studies on renewable systems integrated into industrial processes and a policy section identifying eight issues which may attract or deter industrial stakeholders intending to deploy renewable production assets at their facilities. Commissioned by the IEA Renewable Energy Technology Deployment Program (IEA-RETD), the publication was lead-authored by French-based ENEA Consulting. It is one of the milestones towards an IEA Insights Paper on Renewables in Industry planned to come out in November 2017.

IEA Task 51: Challenges in Urban Planner Education

Submitted by Baerbel Epp on July 27, 2017
Task 51 MapCities and large municipalities all around the world have taken the lead in sustainability, and urban planners find themselves in the important position of having to devise solutions for integrating renewable and energy efficiency measures at local level. Each city has its own unique set of resources and pattern of energy use. But as solar energy is available everywhere to some extent, there will be an urgent need to develop the expertise and skills of solar industry stakeholders in urban planning. Researchers from the IEA’s Solar Heating and Cooling Programme’s Task 51, Solar Energy in Urban Planning, have examined the educational offerings of universities and colleges in nine partner countries (Australia, Austria, Canada, France, Germany, Italy, Norway, Sweden and Switzerland), identified gaps in knowledge and designed solutions to overcome them. 
 

India: New Energy Building Regulations to Boost Solar Heating Market

Submitted by Baerbel Epp on July 24, 2017
Jaideep MalaviyaThis June, the Indian Ministry of Power published an updated version of the Energy Conservation Building Code (ECBC) developed by the Indian Bureau of Energy Efficiency (BEE). The ECBC has established energy efficiency standards and a solar share of hot water demand for newbuilds and refurbished homes and commercial buildings across India. But it will be the task of municipal corporations to issue notifications which mandate compliance with ECBC 2017 regulations in the construction sector in their area. The ECBC was launched in 2007 based on the Energy Conservation Act from 2001. The photo shows a vacuum tube installation for solar process heat at automotive manufacturer JBM Group. Solar industry stakeholders have said that it was regrettable that industrial buildings and applications are not covered by the ECBC 2017.
