Sector coupling still at an early stage

Submitted by Baerbel Epp on July 18, 2018
‘Sector coupling’ has become one of the most well-known terms to describe the transformation of energy markets. It had originally been created for models that use surplus renewables, such as wind and solar electricity, to provide heat and power new means of transport. International organisations – for example, REN21 and IEA – have since established more general definitions and charts to illustrate the process. The figure on the left-hand side is taken from a presentation given by Paolo Frankl, Head of the IEA’s Renewable Energy Division, at the Mexirec Conference in Mexico last September.

Global electricity demand for air conditioning to triple by 2050

Submitted by Baerbel Epp on June 28, 2018
“Growing demand for air conditioners is one of the most critical blind spots in today’s energy debate,” Fatih Birol, Executive Director of the IEA, said as he presented the findings of The Future of Cooling report in May. The chart shows that, in the baseline scenario, cooling is projected to be responsible for between 25 % and nearly 50 % of peak electricity loads in the United States, the Middle East, Indonesia, India and Brazil in 2050. Globally, demand is expected to triple by the same year. The world’s stock of AC units is said to rise to 5.6 billion by 2050, up from 1.6 billion today, which reportedly means an average of 10 ACs will be sold each second over the next 30 years.

IEA´s Renewables Outlook 2017-2022

Submitted by Baerbel Epp on October 31, 2017
IEA Renewables 2017 forecastThe IEA’s Renewables 2017 market report was launched in London in early October. The document, which had been called Medium-Term Renewable Energy Market Report until last year, is published annually and forecasts market development in renewable electricity over the next five years (2017 to 2022). Considering that renewable markets are closely linked and politicians are increasingly looking for cross-sector solutions, we have compiled the IEA’s most important conclusions regarding renewable electricity in this news article. A lack of data on renewable heating and cooling (RHC) means that the IEA does not provide a separate RHC forecast, but instead uses the World Energy Model results published in the annual World Energy Outlook.

IEA Medium-Term Report: Solar Heating and Cooling Not on Track for 2 °C Scenario

Submitted by Baerbel Epp on December 15, 2016
MTRMR 2016The IEA’s Medium-Term Renewable Energy Market Report or MTRMR 2016 again includes a chapter on renewable heating and cooling – and it’s growing in size. The 282-page document published from Singapore on 25 October analyses on 47 pages the current and future market development of four renewable heating technologies: biomass, solar thermal, geothermal and heat pumps. The IEA began to add a renewable heating chapter to its MTRMR in 2013 – back then, it had only 14 pages. The authors of this year’s edition emphasise the fact that onshore wind and solar PV are the only renewable technologies on track for a 2 °C target.
 

Austria: Low Oil Price and Lack of Political Support Weakens Market

Submitted by Baerbel Epp on February 15, 2016
Heating with oilAccording to the ISOL Index by solrico and market data from the industry association Austria Solar, the solar thermal industry is heading into another year of declining markets. Low oil prices and corresponding campaigns of the fossil heating industry have had a substantial impact on this renewable technology. The banner shows the slogan “Heizen mit Öl – das zahlt sich aus” (The Benefits of Using Oil to Heat Your Home) on the website of the Austrian mineral oil industry, which offers grants of EUR 2,500 for the installation of a condensing oil boiler in a single-family building. Austria Solar has also criticised the reduction in the renewable budget of the Austrian Climate and Energy Fund as well as the complicated incentive scheme rules throughout the states. The large-scale project market is what keeps the industry alive. 

IEA SHC: Industry Invited to Join Research Community for Lower Solar Heat Costs

Submitted by Baerbel Epp on October 12, 2015
TASK 54Driving down the costs of solar thermal systems is not only about cheaper collector production. In fact, post-production processes, such as sales, installation and maintenance account for up to 50 % of the price the end customer will have to pay. The new IEA SHC Task 54, Price Reduction of Solar Thermal Systems, wants to investigate those factors and find ways to reduce system costs. The kick-off meeting on 21 to 22 October will be hosted by Fraunhofer ISE in Freiburg, Germany. Researchers and industry representatives from all over the world have been invited to participate. The task spans over three years and includes on average two two-day experts meetings per year. 
 

Solar Cooling 2.0: New Generation Growing Up

Submitted by Baerbel Epp on October 1, 2015
Task 53The workshop New Generation Solar Cooling & Heating Systems held in Rome, Italy, on 23 September 2015 was the opportunity to check the status of both research on and market developments in solar cooling technology. The half-day event, which had about 40 participants, was jointly organised by Task 53 of the IEA Solar Heating & Cooling Programme and the German Eastbavarian Institute for Technology Transfer, OTTI e.V., and took place a day before the start of OTTI’s 6th International Conference on Solar Air-Conditioning. Above all, the workshop provided a platform for presenting the first outcomes of the international research cooperation TASK 53 entitled New Generation Solar Cooling & Heating Systems, which was launched in March 2014, will end in 2017 and involves 10 countries, some from outside Europe (see the attached introductory presentation). 
 

IEA SHC Task 42: Latent Heat Storage Has Huge Potential in the Long Run

Submitted by Baerbel Epp on September 25, 2015
IEA SHC Task 42In their position paper published in August 2015, the scientists of IEA SHC Task 42 (Compact Thermal Energy Storage) summed up the key results of their work between 2009 and 2015. Operating agent Matthias Rommel sees huge potential for latent heat and sorption materials in the long run – in seasonal solar heat storage for small and medium applications, as well as in the building sector. So-called smart grids will also require more heat storage units when devices such as heat pumps and co-generation plants are based on electricity grid requirements. Rommel views the definition of measurement standards for PCM materials as one of the task’s big achievements, which will help in material development. Furthermore, a research group from German research institute ZAE Bayern has performed a first cost estimate of compact heat storage technologies.  
 

IEA SHC: 20 Country Profile Analyse Market and Industry Development

Submitted by Baerbel Epp on September 3, 2015
SHC country members“The Renewable Heat Incentive in the United Kingdom has failed to stimulate the market for solar thermal, which continues to contract. There are technical issues in the regulations preventing the use of solar thermal with other renewable heating systems, such as biomass and heat pumps, and the subsidy rate is relatively low compared to the feed-in tariff for solar photovoltaics.” This clear statement was made by Dr Robert Edwards, Director in the Science and Innovation Group at the Department of Energy and Climate Change (DECC). He represents the country in the Executive Committee of the IEA Solar Heating and Cooling (SHC) research programme and delivered an updated country profile of the British solar thermal market in June 2015. As part of its services, the IEA SHC programme publishes updated market profiles of all 20 member countries each year. You will find the list of member countries online and the link to the country profile at the bottom of each country page. The statement by Edwards is part of the latest UK country profile.
 

IEA SHC: Attractive Solar Process Heat Markets

Submitted by Baerbel Epp on August 28, 2015
fastest growing segmentWhich countries are currently attractive markets for solar process heat? Different sources give different answers to this question. The chart above shows the assessment of the solar industry. More than 30 % of the Austrian solar collector manufacturers in the two surveys in 2012 and 2013 assumed that solar process heat was the fastest-growing segment in their national market. More than every tenth manufacturer in Germany, Mexico and France shared their opinion. The figure in brackets behind the country stands for the number of surveys analysed. Some of the countries, such as Germany, India, Mexico and France, have a support scheme in place which focuses on solar process heat systems.
