Energietübbing for Crossrail?

April 2013: This week’s New Scientist features how “Smart heat is helping building the next energy revolution”. The article (subscription only…)  looks how the use of technologies such as  combined heat and power (CHP) and heat pumps could help “reverse some of the damaging effects that waste heat from our towns and cities is having on the climate ” –  and the use of waste heat from London Underground is also examined:

“As passengers often complain, exhaust heat accumulates in the train tunnels under many of our largest cities. Even on a cold day, temperatures on platforms in the London Underground can reach 20 °C. To harvest that warmth, German companies Züblin and Rehau, together with Arup, have designed a liner for tunnel segments that functions like the buried coils in ground source heat pumps, using the heat generated by engines and braking along with that from the surrounding ground to warm the refrigerant, again by compression. As this transfers the excess energy from the tunnel to the refrigerant, the process also causes the tunnel to cool.”

“The lining – dubbed Energietübbing – was placed into a 54-metre-long stretch of a new high-speed rail tunnel in Jenbach, Austria, to supply the municipal building above with enough heat to completely replace the existing boiler. It is still being optimised, but in its first successful winter it coped with outside temperatures as low as -15 °C. London commuters could soon benefit as well. Crossrail, a railway being constructed under the city, is considering Energietübbing for several segments of the new tunnel, where it too would both cool the tunnel and provide the resulting heat to buildings above.”

A recent question to the Mayor highlights which of the stations on the Crossrail route are planned to integrate heat pump technology to provide waste heat to buildings above.  “Out of the twelve oversite development schemes Crossrail is developing only two will not include a capability for using ground source heat pumps. These are at Woolwich and Limmo, where Crossrail is constructing a vent shaft. At these sites a large proportion of the oversite development schemes are not integrated with Crossrail infrastructure. Future owners of these oversite development schemes will however be able to install ground source heat pump technology within the buildings’ foundations.

A Haringey Green Deal Diary

April 2013: Great blog of a Green Deal ‘journey’ by sustainability expert Sofie Pelsmakers. Sofie started the process with a free Green Deal energy assessment offered to residents and business in Haringey (which is funded through DECC’s recently Green Deal Pioneer Places funding).  These free assessments are still on offer with the deadline recently extended to 30 April – more here.

Having had her assessment finalised – Sofie appears now to be struggling to secure Green Finance:

DECC issued their latest Green Deal and ECO monthly statistics last week with Greg Barker stating that “It is clearly very early days but the latest figures on the Green Deal show that this new market is gathering real momentum. 9,268 Green Deal assessments taking place in just over two months is very encouraging and shows a genuine interest from consumers.

The statistics do not however provide a breakdown of how many of these assessments came out of activities through the  Energy Company Obligation (ECO) process rather than directly as a result of households taking up the Green Deal. Additionally, the Green Deal Finance Company have stated that it is “yet to sign its first Green Deal Plan with a householder, but suggested it would not be long before it did. “There is one good to go and we are reviewing two others””.

Green Deal statistics for London will be available from DECC in June.

Greenwich Peninsula DE network

April 2013: Industry journal Utility Week revealed last week that E.ON is planning to support the development of a district heating development in the Greenwich Peninsula. The brief story states that “The energy company is in talks with the Royal Borough of Greenwich to develop heat networks around the O2 Arena”.

E.ON’s website provides some further detail on their role to date: “Initially E.ON undertook a high level technical model of the Greenwich Peninsula to assess and validate both heat demand and the indicative heat network design. A design audit shortly followed. E.ON is advising the Greenwich Peninsula Regeneration venture on the heat network design and specification provided by other consultancies, ensuring it’s sufficiently robust to be adopted by an ESCo (Energy Services Company).”

The March 2012 Greenwich Heat Mapping Study provides much more information, setting out that the “Greenwich Peninsula cluster focuses on the existing district heating network at the Greenwich Millennium Village and the O2 Stadium site and the proposed district heating network for the Greenwich Peninsula Regeneration Limited (GPRL) site. The new redevelopment site consists of 10,000 new homes and 340,000 square meters of mixed use space.”

The study goes on to say that a wider area heat network could in fact be developed by “engaging with the developers for Heart of East Greenwich, Lovell’s Wharf and Enderby Wharf to gain clarity on progress and potential for linking to wider DE network”.

Greenwich’s Climate Change Strategy from 2011 sets out plans for the wider use of decentralised energy across the borough. Greenwich’s Core Strategy consultation also sets out plans for supporting the development of CHP.

London CRC Performance

April 2013: The Carbon Reduction Commitment (CRC) Performance Table was published a few weeks ago and attracted some media attention on who had gone up and down the table (see Guardian article here). The CRC is a complex mechanism and Government has had to return to tweak the policy time and again to simplify it. Along with the performance table, it appears the Chancellor’s view of simplification is, as set out in his Autumn Statement (December 2012), to get rid of the CRC altogether.

“1.127 The CRC’s Performance League Table will be abolished, to simplify the scheme further. A full review of the effectiveness of the CRC will be held in 2016 and the tax will be a high priority for removal when the public finances allow.”

For those new to the CRC, they should be made aware the original plan of the policy was to recycle the funds obtained from participants purchase of carbon permits, into sector-wide energy efficiency funding. The incoming Government however changed plans in 2010 and the Chancellor simply took all the funds into Government. It’s more than likely the Government would like to see the back of the CRC sooner, however, it does bring in close to £1bn to the Exchequer a year and this will increase again, as  the 2012 Autumn Budget highlights:  “2.88 The forecast allowance price remains unchanged at £12 per tonne of carbon dioxide in 2013-14 and £16 per tonne of carbon dioxide in 2014-15. From 2015-16 onwards, the allowance price will increase in line with the RPI.”

Back to the performance table: how did London do?

Disabled Facilities Grant to fund heating

April 2013: The Department for Communities and Local Government announced last week new funding to help councils fund the adaptations disabled people need to live independently in their own home. The press release states that “Ministers have protected the Disabled Facilities Grant programme for the last 3 years, with a further £185 million expected in next year’s funding.

Included in eligible types of work for funding are:

  • adapting heating or lighting controls to make them easier to use
  • improving or providing a suitable heating system

A document setting out the allocation awarded to each local authority is provided here. Looking at London councils , it can be seen a total of £23.5m has gone to the capital – a breakdown of each borough’s funding is provided below:

Decarbonising London’s electricity network

March 2013: An update on  progress of the Low Carbon London programme as it moves into the trial phase – the key areas for which are:

  • Smart metering (SM) – monitoring residential and commercial electricity use and trialling variable tariff pricing to shift consumption behaviour.
  • Small-scale embedded generation (SSEG) – quantify generation output, understand demand and manage techniques for accommodating these connections.
  • Electric vehicles (EV) – understand and influence EV charging patterns and manage the impact on the electricity network.
  • Distributed energy (DE)/Distributed generation (DG) – active network monitoring (ANM) – quantify generation output, understand how to facilitate and manage DG and how active control can be used by DNOs.
  • Demand response (DR) – understand the potential to postpone/defer electricity network reinforcement during peak demand.

Further information on Low Carbon London here.

4MW of PV added in London

March 2013: Ofgem’s new FIT quarterly report provides an update on the take-up of Feed in Tariff eligible technologies across the UK. London (as at 31 December 2012) has a total of 39.38 MW of FIT renewable capacity installed – as with the rest of the country, the vast proportion of this capacity is made up of PV (99% in London).  This is an increase of 4.25 MW of capacity over the previous quarter.

Progress remains slow in London which  – with the North East – trails all other UK regions by a significant margin. See graph from FIT report below highlighting the number of installations by region.

Previous posts discuss London’s slow performance on FIT take up here.

The Future of Heating in London

March 2013: The Government’s Future of Heating policy paper released yesterday gives prominent coverage to activities underway in London to promote the use of decentralised energy systems through the use of district heating and high efficiency Combined Heat and Power (CHP) systems. The paper includes the following:

  • A case study of The Shard CHP heat network [p41]
  • How Islington Council, the GLA  and UK Power Networks are working together on “a proposed extension of the existing Bunhill heat network that will capture and use identified sources of waste heat produced within the area, such as from a nearby electricity sub-station. This project will help London and its boroughs to identify, capture and make use of urban sources of waste heat and play an important part in developing their lower carbon, lower temperature heat networks ofthe future” [p43] Continue reading…

Getting into Hot Water…

March 2013: Presentation made at the the recent Combined Heat and Power Association (CHPA) district heating conference, by Bob Fiddik, Sustainable Development & Energy Team Leader at Croydon Council, giving some valuable insights into the challenges faced when developing heat networks. The presentation includes:

  • Some of the history behind the failure of the SELCHP energy from waste plant to develop the expected district heat network anticipated when it was built – and the recent work now being undertaken to help turn this around
  • The unhappy circumstances that led to the stalling of the hugely exciting Elephant & Castle heat network project, and
  • An update to the major district heating scheme currently being planned for Croydon.

Slide 14 of the presentation sets out – as challenging as circumstances have been in the past – things are not unfortunately getting easier:

Threefold increase in fuel poverty in London over past decade

27 March 2013: A parliamentary question asking about the numbers of fuel poor households in the UK, including for numbers at the regional level, helps provide an indication about the growth in fuel poverty in the capital over the past decade.

Data is only available as yet to 2010 (see PQ link above for references): updated statistics for 2011 and 2012 will be made available in June of this year. London is common with most other areas in observing a threefold increase in the numbers of fuel poor households as a consequence of increasing fuel prices – most notably from 2005/06 onwards.  The Government is however currently working on a redefining the definition of fuel poverty and the proposals – as set out out in a consultation paper late last year – are anticipated to have a significant impact in London, as a consequence of housing costs now being taken into consideration (see earlier post here for details).

The Big London Energy Switch

March 2013: The ‘Big London Energy Switch’ collective switching scheme was initiated earlier this year after securing £686,655 in funding from DECC (see earlier post here for full details). Those involved include London Councils, with 18 other boroughs and with the Royal Borough of Kingston as lead. Kingston is also where Secretary of State for Energy, Ed Davey, a longtime support of collective purchasing, is the local MP (see here for further details). The other 17 London boroughs are: Bexley, Brent, Camden, Croydon, Ealing, Enfield, Greenwich, Hackney, Haringey, Islington, Lambeth, Merton, Newham, Richmond, Southwark, Sutton and Waltham Forest.

A recent London Councils briefing paper highlights that three other boroughs (Lewisham, Harrow and Tower Hamlets) are now also supporting the scheme but are not in receipt of DECC funding.  A Big London Energy Switch website has now been established along with an introductory video to the initiative.

The Scheme is currently procuring a switching provider with support from law firm Pinsent and Masons.
