District Heating Heats Up in the U.K.

District heating is a hot item in the United Kingdom. Earlier this month, the Building Engineering Services Association (BESA) said that it will create the UK’s first test standard for heat interface units (HIUs).

HIUs are the devices that divert heat from the network into structures. This is an obviously critical element that, according to the story in Heating and Ventilation, often fails to perform adequately in U.K. district heat networks.

The test methodology was adopted from a Swedish method under funding from the Department of Energy and Climate Change (DECC).

District heading also is seen as a key tool elsewhere in the U.K. On January 24, the Scottish government released a draft climate change plan. The government aims to produce 80 percent of residential heating from low carbon sources. Scottish law firm Brodies LLP points out that low carbon is not synonymous with renewable and commercial and industrial use are not included. It calls the target “transformative” nonetheless.

The analysis at Lexography says that district heating is one of the strategies that will be used. Scotland plans to regulate district heat. The piece points out Scotland will do so before England, which also has plans to regulate. Usually, the commentary says, England leads and Scotland tweaks and adopts.

Decentralized Energy this week that the U.K.’s Chief Energy Advisor at the Danish Embassy said that the British district energy business is booming. Ian Manders said that the value of the market has risen from £76 million to £350 million in just one year.

The newest member of the district heating club in the U.K. is IKEA. Last week, the company said that its new store in Sheffield will include district heating.

BESA publishes district heating standard for HIUs

A new standard which will tackle the "Achilles heel" of district heating networks and improve the overall efficiency of schemes is to be published by the Building Engineering Services Association (BESA).

The standard will be used to compare manufacturers' products and equipment types to help network designers evaluate performance against their design parameters.

It will also be used to create a comprehensive database and improve the industry's knowledge of heat interface unit (HIU) performance to inform future network design.

The performance of HIUs, which are used to extract heat from the network to feed individual buildings, is critical to occupant satisfaction levels and the overall efficiency of the schemes in terms of return temperatures and network sizing.

HIU are often the reason for networks failing to meet their efficiency targets. BESA said HIUs have proven to be an "Achilles' heel" of district heating networks.

BESA's technical director Tim Rook said: "This standard is, therefore, a major step forward for UK heat networks and it is a real accolade for BESA to be asked to publish and disseminate it on behalf of the industry."

The standard is being adopted from a test regime initially developed by energy consultancy FairHeat which was adapted form a well-stablished Swedish methodology to suit typical UK operating conditions as part of a research project funded by the Department of Energy and Climate Change.

FairHeat managing director Gareth Jones said: "BESA is very well respected in the sector and we are delighted they have decided to take our regime and publish it as a standard.

"It is amazing to see how far the regime has come from a research project, developed with grant funding, to a recognised standard that will be used across the sector to improve heat network efficiency."

Geothermal district heating could become reality in Stoke-on-Trent by 2019

If progressing as planned, district heating fuelled by geothermal energy could become a reality for the first residents in Stoke-on-Trent in the UK, in a project by the municipality and private company GT Energy.

A joint project by the city of Stoke-on-Trent in the UK, and private developer GT Energy continuing development of a geothermal district heating network.

As part of the project – so local news – about 1,000 people could benefit from the heating scheme in the early stage as early as 2019.

The GBP 52 million ($64 million) project would connect high-density housing the municipality with geothermal heating. With the project customers are expected to become independent from price fluctuation sin fossil fuels, while reducing carbon emissions.

Around GBP 20 million have been secured from the government through a City Deal, with private company GT Energy to invest additional millions of pounds into the the geothermal plant.

The city council secured GBP 19.75 million (USD 24 million) from the Government for the DHN project through its City Deal.

The local community welcomes the project, as currently around third of the people’s income goes into paying for heating during the colder time of the year.

Direction of heat policy to be outlined in carbon plan

The government will start to outline its plans for the decarbonisation of heating when it publishes its latest emissions reduction plan in 2017, business and energy minister Baroness Neville-Rolfe has revealed.

It will need to "thoroughly re-assess the evidence" before establishing a long-term direction for policy over the next few years.

"Our plans on heat will feature in the emissions reduction plan next year," said Neville-Rolfe, at an event held by the think tank Policy Exchange. "We are determined to do more and we know that this will require determination and a clear line of sight."

She told attendees heat is "one of the more difficult energy uses to decarbonise" and there is currently "no consensus on the best technology or mix of technologies to achieve the scale of change needed".

"We need a clearer shared understanding of the potential, the costs and the benefits of different approaches," she added. "And whether there are practical solutions to the challenges we know they involve."

Neville-Rolfe said it is important to start the process now if Britain is to meet its 2050 carbon reduction targets in the most cost-effective way: "Our ambition is to be able to agree in the next few years on the right long-term direction for heat policy."

There have been mounting calls for the government to address a ‘policy gap' when comes to the decarbonisation of heating.

Policy Exchange has urged the government to "completely re-think" its most recent strategy. At a cost of £300 billion, it said the plans outlined in 2013 to install electric heat pumps in four out of five homes by 2050 would be a "colossal waste of money".

The Committee on Climate Change warned in October that progress on heating has stalled and that emissions targets will not be met unless the government puts in place "a credible new strategy". Last month the UK Energy Research Centre (UKERC) called on the government to produce a white paper to address the gap in policy.

Permanent secretary for the Department for Business, Energy and Industrial Strategy, Alex Chisholm, revealed in October that the latest emissions reduction plan will be published in February. The plan will lay out how the government intends to meet the fifth carbon budget for 2028 to 2032 which it agreed to in June.

Churchill College, Cambridge furthers sustainability goals using a new Veolia CHP

The service will replace the previous CHP that had completed over 120,000 generating hours over a 22 year life - equivalent to a vehicle completing over 5 million miles or 208 trips around the earth. After years of successful delivery of electricity, heat and hot water to the campus the college has now decided to take advantage of the benefits of a modern more efficient unit to support their academic and research activities in mathematics, science and technology, the arts and humanities.

The new CHP uses the latest lean-burn technology to generate low carbon electricity and heat for the campus, and will save an estimated 5,000 tonnes of CO2 emissions. Veolia’s CHP helpdesk will provide lifetime monitoring with maintenance provided by the company’s nationwide field service teams.

Commenting on the new contract, Gavin Graveson, Veolia’s COO Public and Commercial said “This latest application of CHP demonstrates our long term commitment to deliver energy efficiency and low carbon energy to higher education. We currently have 25MWe of CHP capacity that provides energy on over 60 University campuses, supporting their education and research facilities, and housing more than 200,000 students. ”

Receiving its Royal Charter in 1960, Churchill College is the national and Commonwealth memorial to Sir Winston Churchill and is situated on 42 acres in north-west Cambridge. The College is renowned for its academic standing and has produced twenty-nine Nobel Prize winners among its past and present members.
