Mark Jacobson and Mark Delucchi recently published two papers in Energy Policy expanding upon our article on 100% wind, water, and solar power for the world, published in Scientific American in November 2009. I am attaching corrected in-press proofs of the articles. Mark and I continue to work on various aspects of this, so we […]

Dave, Below is the link to the GH 40 post (2 years full time work based in Petten) we have open (closing date 31.01.2011) for a co-author of the rewriting of the Large Combustion Plant Best Available Techniques Reference Document (BREF). We are looking for someone with a few years of experience in the power […]
Read MoreHow much of UK electricity could come from the burning of combustible wastes from both domestic and industrial sources?
David In March 2005 the Institution of Civil Engineers (ICE) and the Renewable Power Association (RPA) published a report titled “The Quantification of the Potential Energy from Residuals (EfR) in the UK (Lee P et al. 2005). A briefing on this report was included in Energy Journal 160, (Crudginton A. 2007). The report indicated that […]
Read MoreTiny Tech Steam Engines for Biomass to power
Dear Friends, Dave Andrews has suggested me to appraise you about my activity of steam engines and steam power plants which, I think, will play very vital role in shaping the economy of many developing countries in future. Just to get the idea of my steam engines, you can watch the following URL on […]
Read MorePrivate client manager Invicta is to launch a £300m fund targeting the biomass industry to cash in on government targets for renewable energy
( Bruno Prior, MD of Forever Fuels, comments on the Invicta announcement – these are Bruno’s personal views, not those of Claverton Group)
“Just one little problem (well actually, several, but this one’s a good one).
Invicta have been shy about whose technology they are using. We sent one of our team to a public meeting in Edinburgh, to ask the question. He was told that Organics would supply the kit, in 1.2MW modules. Happily for us, Rob Eden, Organics’ MD, is a long-time associate of ours (going back around 25 years), so we contacted Rob to express interest in a gasifier or pyroliser if he had 1.2MW modules

Richard Hanson writes: To answer your question, no – I’m afraid we don’t have a wood gasifier. But we do have several plants which are being used very successfully on wood gasifiers to provide gas cleaning between the gasifier and the compressor or engine, depending on the system configuration. The core technology is the V-texTM […]
Read MoreOwning and Operating Costs of Waste and Biomass Power Plants
Claverton Energy Conference, 23/24/25th October 2009
Dave Andrews, DAEC
Here are some broad brush head line figures for the owning and operating of a particular kind of advanced staged combustion power plant, obtained from a leading manufacturer, suitable for biomass, waste materials and waste wood. The process is essential combustion, but is referred to as gasification / combustion, meaning the material is first charred on a grate, with the off syngas being burnt in a separate adjacent and low level refractory chamber. The char is then burnt at a later stage as it moves down the great. This leads to greater burn up of fuel and lower emissions. The syngas combustion is maintained within the ceramic, and special gas flows prevent the contaminants in the gases fouling and degrading the ceramics.

Need a regular up to date source of hard info on renewable energy? Renew is a 36 page newsletter on renewable energy developments and policy which has been produced by Open University Professor Dave Elliott without a break bi-monthly since 1979. It’s widely seen as a reliable and up to date source of information, news […]
Read MoreHas Professor MacKay FRS, Chief Scientific Advisor to DECC, underestimated Britain's potential for Renewable Energy?
Today, The Times has claimed that Britain’s potential renewable resources are insufficient to meet demand, and therefore that Britain needs new nuclear plants. This is reported as having been stated by the new Chief Scientific Advisor to DECC, Professor David MacKay FRS, the author of the free online book: Sustainable Energy Without the Hot Air – though it appears that The Times invented this quote. Nevertheless, the claim that Britain cannot live on its own renewables, is also made in his book.
However, the claim is not true.
On the professor’s own (underestimated) calculation of Britain’s renewable potential, it is possible for Britain to power itself from wind and solar. Current energy demand (heat, transport & electricity), is 98kWh per person per day (245GW), and the professor’s book identifies 68kWh/d (170GW) of wind onshore and offshore, and 55kWh/d (137.5GW) from photovoltaics, which together gives 123kWh/d (307.5GW). That means that even ignoring wave, tidal, geothermal and biomass, Britain’s renewable potential supply just from solar and wind substantially exceeds our energy demand.
Read MoreBiomass combustion plants – a Claverton member is interested in finding sites / locations with large capacity connections to the local power network or National Grid
A member of the Claverton Group is interested in finding sites / locations with large capacity connections to the local power network or National Grid – typically these might be defunct industrial sites, or existing industrial sites with spare capacity in an industrial sort of location where planning permission for a biomass combustion plant might be more readily obtained.
These are for biomass plants capacity 1 MW – 10 MW.
If you are aware of any please get in touch using the claverton contact form.
Kind Regards,
Dave Andrews
