Enfield Gasification Scheme

21 November 2011: An update on Irish developer Kedco’s plans to develop a biomass gasification scheme in Enfield which it believes have become more positive as a result of the recent proposed changes to the renewable obligation

The project received planning permission in October 2010 to build a c. £45 million biomass wood gasification plant in Enfield capable of generating 12MW of electricity and 10MW of heat and – as the article linked above explains – has secured a supply deal with a company processing waste wood from construction and demolition. Kedco report that tenders currently being prepared to source a suitable contractor for the proposed construction of the plant.  Details submitted at the time of application in relation to a ‘heat output assessment’ for the facility can be viewed here and para 6.3.1 onwards  of the planning officer’s report (report also here) on the application provide details of the scheme’s proposals to export heat to some nearby sites.

More challenging times for renewables in London?

21 October 2011: The Government’s proposals for future Renewable Obligation (RO) banding levels for different renewable electricity levels have been published today for consultation. The bands set the level of subsidy provided through granting Renewable Obligation Certificates (ROCs) –  awarded per MWh (megawatt-hour) of electricity generated –  and range from 0.5 ROCs to 2 ROCs per MWh depending on the technology. The ROCs programme runs in tandem to the Feed in Tariffs (FIT) mechanism but is applicable to larger renewable technologies, generally above 5MW capacity.

The consultation moves to providing longer term guidance on the levels of support available to renewable generators whilst also reducing the levels of ROCs support awarded to many technologies and also introducing an element of regression as in the FIT regime (ie a percentage reduction to the levels of support year on year).

Progress on developing larger renewable energy projects in London has been incredibly slow, with only a few notable schemes based around the use of sewage gas at water treatment plant, the capture of  landfill gas, and single larger-scale wind project.

DECC’s proposals will do little to help and potentially much to hinder the situation for London. Key renewable technologies being supported for London such as advanced gasification and pyrolysis are to have their levels of support reduced (see Table 2 of the consultation paper for the full list of specific proposals). These are already high risk projects and hence this will do little to get these nascent technologies off the ground. Ditto for urban-based anaerobic digestion plant which are also having their levels of support reduced.

Similarly reducing support to energy from waste CHP without clarifying the level of Renewable Heat Incentive (RHI) tariff that might also be available will do little to inspire confidence in operators considering converting their plant to CHP mode and investing in new district heating infrastructure.  Cities are already severely limited in their ability to contribute to the UK’s ambitious renewable energy targets: waste does however provide a key opportunity but project costs are typically much higher due to land value amongst many other factors.

More needs to be done to support the growth of renewables in London and other cities to exploit opportunities to deliver low carbon heat and power to their communities.  Government should perhaps consider introducing a ‘ROC uplift’ for urban based schemes to help bring these more challenging city renewable schemes forward – that is – an additional 0.5 to 1.0 ROCs for those schemes developed in cities, with a priority given to those that deliver decentralised heat networks as part of their scheme.

Mayor overturns Merton refusal to allow development of new AD scheme

October 2011: Following Merton Council’s planning application refusal , the Mayor has today approved waste management firm Sita’s plans for an anaerobic digestion and material recycling facility in Mitcham.  Sita can now build an anaerobic digestion plant handling 40,000t of waste per year, down from the original scheme of 100,000t of waste. It will deliver between 1.1 and 1.7 megawatts of electricity, enough to power the site and export around 8 GWh (gigawatt hours) of electricity per year – equivalent to powering around 2,000 homes –  exporting  around 6.2 GWh of power to the grid per year.
The detailed planning report on the Sita application can be accessed via the Merton’s Planning Application’s Committee meeting of 8 September 2011.  The original energy statement for the development, an updated energy statement responding to queries raised by the GLA, and a district heating study for the immediate area around the anaerobic digestion plan in Merton are all available to download from the Merton’s planning website here [word search for ‘energy’ to quickly locate all three documents].
Some additional useful information is provided in articles at the Wimbledon Guardian and at letsrecycle.com

Three schemes bid to generate heat and power from North London’s waste

October 2011: Three bids have been submitted to the North London Waste Authority (NLWA) to generate energy from the 300,000 tonnes of solid recovered fuel (SRF)  created from the 500,000 to 600,000 tonnes of North London’s waste that cannot be recycled  or composted.
The NWLA is a statutory waste authority managing the disposal of municipal waste from seven London local authorities (Barnet, Camden, Enfield, Islington, Hackney, Haringey and Waltham Forest) and this procurement is one of two that NLWA is running to provide a “long term and sustainable waste management solution for North London”.  A separate procurement is being run that will involve recycling or composting half of North London’s waste, producing the fuel and minimising the landfilling of municipal waste.
The contract for the use of SRF will be available from 2015 for up to 25 years and the NLWA states that it “is striving to achieve the most efficient form of energy recovery. This could be with the fuel being used in a Combined Heat and Power (‘CHP’) plant, located close to where the energy demand is.”
The NWLA have provided updated details of the three bids, all of which utilise CHP technology  on the following news release.

  • Covanta Energy project is the only one based in London and is proposing a Combined Heat and Power plant at the Tate & Lyle sugar refinery site at Silvertown, East London. The Covanta proposal involves the transport by barge of SRF from Edmonton to Silvertown and this will support the further development of London rivers for freight transport use. Covanta will shortly begin consultations with the local community and relevant authorities ahead of a planning application in mid 2012.
  • E.ON/Wheelabrator Technologies is proposing a CHP plant at DS Smith Paper’s site at Kemsley Mill, Sittingbourne, Kent.
  • Veolia Environmental Services (UK) wants a CHP enabled power plant at an existing industrial site in Hoddesdon, Hertfordshire.

The winning proposal will be selected from one of the three shortlisted candidates during the next 12 months using an evaluation framework that focuses on the quality and cost of the solution.
Further information on how SRF is produced is set out by the NWLA here.

New Hackney Waste to Energy Plant proposed

August 2011: An article in this weekend’s Hackney Citizen highlights the recent consultation by Tower Hamlets on the Fish Island Area Action Plan (AAP), which includes consideration of a new waste to energy plant.
The Fish Island AAP states: “The Council requires a new waste management facility in the Borough to handle approximately 150,000 tonnes of waste per annum and is exploring the potential to use emerging technologies to generate energy from the waste.” and that
“There is an opportunity to develop a new green waste to energy facility in Fish Island south” which could be connected to “the waste management facility to the Olympic Energy Centre to create an area-based zero or low carbon energy network for new developments in Fish Island.”
The article goes on to quote London Assembly’s Darren Johnson who says of the proposal:  “We need to look at new ways of dealing with waste as we cannot continue sending it off to landfill sites outside London. But getting the right sort of technology is absolutely vital. Mass burn incinerators are an outdated polluting technology and we certainly don’t want to see any more of those in London. There is a role for more sophisticated energy from waste plants, particularly anaerobic digestion which produces green energy from food waste.”
The consultation includes a specific question on the proposal asking: Do you agree with the principle of a borough waste to energy facility located in Fish Island? If so, how should a site be identified? – however  this phase of consultation finished on 15 July 2011.

Recycling Cooking Oil in London

July 2011: The Committee on Climate Change are currently undertaking a review of bioenergy and took a trip to have a look at the work of Uptown Oil who  collect used cooking oil from about a thousand sources in London – including Young’s pubs, Selfridges and Hackney Borough Council – to produce biodiesel.
Business Green article published last week highlighted that Carluccio’s Restaurant chain – which has around 20 cafes in London – announced that it has signed a deal with biofuel firm Convert2Green to be converted into biofuel.  Other biofuel suppliers in London include:
Uptown Oil based in Borough
Pure Fuels based in Edmonton
Proper Oils who work with a  Croydon Council collection scheme
Uptown have also been selected to supply biofuel to PWC’s new HQ whose energy will be partially supplied by a trigeneration scheme (combined heat and power with cooling) – one of London’s only biofuelled CHP schemes.
Figures for the amount of cooking oil collected in London and be turned into biofuel do not appear to be available, however, a study reported on by the London Assembly in 2009 indicated that 37,000 tonnes of used cooking oil is available in London and the DfT’s latest biofuel statistics state that the “largest single feedstock for UK biofuel was used cooking oil (314m litres, 26% of total biofuel supplied)“. London’s Draft Waste Municipal Waste Strategy commits that the “Mayor will, through his Food to Fuel Alliance, aim to catalyse at least five exemplar food waste projects in London…the Alliance will support food waste projects that generate renewable heat and power (including transport fuel), and compost material for local use.”
