IEA SHC: Thirty Net Zero Energy Buildings in One Book

Submitted by Baerbel Epp on May 2, 2017
The joint SHC Task 40 / EBC Annex 52 project Towards Net Zero Energy Solar Buildings has been one of the largest of the Technology Collaboration Programmes IEA Solar Heating and Cooling (SHC) / Energy in Buildings and Communities (EBC). As many as 86 experts from 19 countries collaborated in this project, which ran between October 2009 and October 2013. This April saw the publication of a book titled Solution Sets for Net Zero Energy Buildings, which presents 30 case studies of Net Zero Energy Buildings (NZEB) from all around the globe. 
 

IRENA: Renewable District Heating and Cooling Roadmap to 2030

Submitted by Baerbel Epp on April 27, 2017
District Heating PotentialThe International Renewable Energy Agency (IRENA) has published an industry roadmap for Renewable Energy in District Heating and Cooling (DHC) as part of its REmap 2030 project. This study analysed the current state of the DHC market in eleven countries – with a focus on district heating in seven and one on district cooling in the other four – and examined the long-term potential of the two technologies in these countries (see the attached PDF). The countries chosen for the study have distinctly different market environments. Two of them are Denmark and Switzerland, which have had the highest share of renewables in their energy supply (around 40 %); a third one is China, the largest market for DHC today, but one on which renewable energy has yet to play a role at all. The chart shows the key factors impacting the potential of renewable DHC. The aim of the renewable energy roadmap (REmap) programme is to show a path towards doubling the share of renewables in the global energy mix by 2030.

The Show represents the entire spectrum of the industry including: HVACR manufacturers, engineers, contractors, OEMs, facility managers, and other professionals. In addition, the visitors will find over 100 educational seminars, workshops and new product presentations. According to show organiser International Exposition Company, about 65,000 attendees registered for the 2017 AHR Expo.

Miraah in Oman: “Ahead of Schedule and Under Budget”

Submitted by Baerbel Epp on March 25, 2017
GlasspointReplacing gas with sunshine for enhanced oil recovery (EOR) is a cost-effective solution. This is the key message of US-based company Glasspoint, which has mobilised the biggest investment ever in a solar steam-producing unit in Oman. State-owned Petroleum Development Oman is building a concentrating solar thermal collector field called Miraah next to the Amal West oilfield. Once complete, it will generate more than a gigawatt of solar thermal power to drive EOR operations – saving Oman about 5.6 trillion BTUs of natural gas each year.

USA: Commercial Systems Dominate Californian Solar Thermal Market

Submitted by Baerbel Epp on March 24, 2017
California Incentive ProgrammeThe California Solar Initiative (CSI) – Thermal Program seems to have stabilised at around 20,000 m² (or around 200,000 ft²) of subsidised collector area per year. Commercial applications dominate the statistics, although there was a spike in the share of residential systems in 2016. The peak in applications for commercial pool heating in 2014 was due to the late addition of this type of system to the state subsidy scheme. It took almost a year before the level of incentives and other requirements were set, so that all the applications piling up over that period had to be processed in 2014. The data in the chart was provided by the California Public Utilities Commission (CPUC) and shows the subsidised and installed collector area for each year.

World Map of Solar Process Heat Specialists 2017

Submitted by Baerbel Epp on February 22, 2017
Worldmap Process HeatIndustrial solar heat is far from being a standard yet, but it is more widespread than you might think. The first World Map of Solar Process Heat Specialists shows 71 companies in 22 countries which reported almost 400 reference systems. Together with additional plants included in the online portal ship-plants.info, the world market for industrial process heat comprises at a minimum 525 plants with an collector or mirror area of at least 416,414 m².

USA/California: CALSEIA´s New President Promises to “Keep SHC on the Agenda”

Submitted by Baerbel Epp on February 16, 2017
The California Solar Energy Industries Association (CALSEIA) named Ed Murray, a solar expert with more than 30 years of experience in the field, its new president in early January 2017. He succeeded Rick Reed, Director of California-based collector manufacturer Sunearth. Murray, a 25-year member of CALSEIA, is President of Aztec Solar, a solar heating and solar electricity system supplier from Sacramento, California. “He’s the right person to lead CALSEIA in the uncertain times ahead,” reads the press release sent the day after the election. “I attend meetings in the states and in Washington DC to make sure that SHC is kept on the agenda and not completely overshadowed by solar PV,” Murray describes his commitment to solar thermal. The photo shows Murray (right) and Anthony Rendon, Speaker of the California State Assembly.

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.
 

USA: Californian Solar Process Heat Potential and Gas Price Competitiveness

Submitted by Baerbel Epp on November 19, 2016
Researchers at the US National Renewable Energy Laboratory (NREL) have observed a renewed interest in solar process heat applications in recent years, mainly thanks to “the improvement and proliferation of solar collectors for electricity generation and the development of sophisticated solar collector modelling tools.” Last year, two of those researchers – Parthiv Kurup and Craig Turchi – conducted a study on the potential of solar process heat provided by concentrating collector technologies in California (see the attached document). This study, entitled Initial Investigation into the Potential of CSP Industrial Process Heat for the Southwest United States, was supported by the US Department of Energy and was published in November 2015. The chart taken from it shows the annual energy use of steam in industry segments which utilise the largest amount of gas. The study’s authors found the temperature range from about 120 to 220 °C to be of great interest, as it enables the use of concentrating optics and of water as the heat transfer fluid.
