The topic of this issue is The role of heat pumps in smart grids and smart cities. The Foreword and Column set the background, while the topical articles cover capacity control as an enablig technology, and the role of heat pumps in district heating and cooling. The topic of this issue will also likely be the subject of other articles in later Newsletter issues during 2012.
With this issue, we are introducing a new type of article, the Strategic outlook. As for the Market reports, we plan to include one Strategic outlook in each issue.These will be national overviews, with UK as the first one.
We also want to remind you of, and highly recommend, the Heat Pump Programme Symposium (previously: Open Conference), which will take place in conjuction with the Chill¬venta, on Monday October 8, in Nürnberg, Germany.
Enjoy your reading!

Welcome to the Heat Pump Programme Symposium in conjunction with the Chillventa, October 8, Nürnberg, Germany!
|
|
We, the Heat Pump Programme, will hold a Symposium (previously called Open Conference) open for all visitors of the Chillventa Congressing day (October 8).
During this Symposium, work and visions of ongoing and planned HPP Annexes will be presented. There will also be invited speakers, with presentations on hot subjects, such as the ETP 2012 (by its coordinator at the IEA), heat pumps in smart cities, heat pumps and energy storage, heat pump research in the US, and others.
The schedule for the Symposium is close to finalized, and will be posted on the Heat Pump Centre website (www.heatpumpcentre.org). Please reserve the day, and let us know your interest by sending an e-mail to johan.berg@sp.se.

Maryland governor signs landmark geothermal heat pump bill
|
|
In the US, Maryland Governor Martin O’Malley has signed the Renewable Energy Portfolio Standard - Geothermal Heating and Cooling bill into law, making Maryland the first state in the nation to allow utilities to claim credits for the installation of geothermal heat pumps. The legislation makes GHPs an accepted technology for utilities to use toward earning Renewable Energy Credits under the state’s Renewable Portfolio Standard.
Geothermal heat pumps address one of the biggest consumers of U.S. energy – buildings. Buildings account for more than 70 % of the nation’s electricity usage, and geothermal heat pumps have the potential to reduce energy use by as much as 40 % to 70 % in a typical building.

Investment in building renovations is a priority in the EU
|
|
The European Union's next budget should focus more on the energy-efficient renovation of buildings, European Commissioner for Energy Günther Oettinger said after member states officially agreed on the EU's intensely negotiated Energy Efficiency Directive. Speaking after the 16 June meeting of energy ministers in Luxembourg, which marked the official deal on the Energy Efficiency Directive, Oettinger warned member states that there will be no ways of getting around the new compulsory measures. To top this measure, member states agreed, as a compromise, to also commit to 2050 roadmaps for the energy-efficient renovation of almost the entire building stock.

China now largest HVAC market
|
|
In addition to being the largest producer of heating, ventilating and air conditioning products in the world, China is now also the largest market for HVAC, a new report claims. The top three Chinese manufacturers, Haier, Midea and Gree, can supply 50% of the world's demand for HVAC products, according to the report by Frost & Sullivan.

The Growing Role of Heat Pumps in a Smart Grid Era
|
| Ron Domitrovic, K. R. Amarnath, US |
|
Heat pumps based on the vapor compression platform are here to stay, as an entire new family of products are beginning to work their way into the market. Variable capacity advancements are enabling what was an inherently single-speed, single-capacity technology, to mature into an advancement better able to match capacity to load. This capacity flexibility can make advanced heat pumps an attractive tool for electric grid demand control. Unfortunately that flexibility is difficult to characterize through the established methods of rating, and likewise difficult to promote through existing channels. There is much work to be done in properly describing the potential of this technology family, in the laboratory, in the field and in modeling tools.

Heat pumps – A key technology in future district heating and district cooling systems
|
| Jørn Stene, Norway |
|
Heat pumps represent an important technology for district heating and cooling systems, since they utilize renewable heat sources/sinks and so reduce primary energy consumption and greenhouse gas emissions in comparison with boiler systems. Current state-of-the-art technology has a maximum outlet water temperature of 90 °C, which means that heat pumps are applicable even in high-temperature systems. The most promising and environmentally benign working fluids for the future are ammonia (R717) and HFO1234ze, which will replace R134a. Carbon dioxide (CO₂) is also an interesting option in district heating systems with low return temperature.

Market report

The German market: upwards again
|
| Gregor Dilger, Bundesverband Wärmepumpe, Germany |
|
The German heat pump market is characterised by keen competition and discerning consumers looking for products which are both efficient and economic. After two years of consolidation, sales volumes are rising again, especially because of the increasingly popular air-to-water heat pumps. Recent drilling incidents have led to higher quality assurance of the drilling procedure in the federal state of Baden-Württemberg – maybe a model for other federal states as well. The German heat pump market is in motion – with an upward trend.

Strategical Outlook

Strategic outlook for the UK
|
| Penny Dunbabin, Department of Energy & Climate Change, UK |
|
This article presents the strategic outlook for heat pumps in the UK up until 2030. It presents the principal Government policies designed to increase the uptake of heat pumps, both in the domestic and the non-domestic sectors. Ensuring that UK installers have the necessary skills to install heat pumps is another key element, and Government has worked closely with industry to develop new installation standards, which are now in force. Finally, the article summarises some of the research projects undertaken by DECC to improve integration of heat pumps in heating systems.
