Reply |Mark Delucchi to energy-discuss. show details 21:34 (12 hours ago) I tend to agree with Mark B. here. FWIW, the IEA report mentions algae but doesn’t feature it in its analysis. I’ve seen a few LCAs of algae fuel, and and the results are not particularly impressive. The IEA report includes algae in one […]Read More
Hello Nick You touch on various topics that I have an interest in. First: combustion of wood and other biomass for energy production. The options break down as: Co-Combustion of the biomass in coal power plants, displacing coal (no char remains). Gasification (burning in limited oxygen supply, c.10% char) Fast pyrolysis (no oxygen, a few […]Read More
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 […]Read More
I think Haiti needs Jatophra like it needs another earthquake I’m sure they would much rather have a little help to rebuild their lives, housing and infrastructure;- notably absent from all the international organisations and charities. They are more likely to need Food. Food and Water? – a seawater Greenhouse ?. For Energy – a […]Read More
Hi Dave and Chris Can I add my bit? UK homegrown biofuel could, at extreme, only supply 3 or 4% of UK transport fuel. Ethanol is such poor EROEI and competes directly with food, wheat, sugar, it should not count. We only have ~6M hectares of ploughable land (as in WWII). The figures for WWII […]Read More
Comments are invited on the two gasification articles found on the The Guardian website today. They seem to have been written on the basis of a Press Release, without much background checking. I don’t want a bad word said about the author, Alok Jha, who is lovely, but I really think we need to unpack […]Read More
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.

POST NOW FILLED Applications are invited for an exciting 3 year studentship to develop biogas fermentation technology. A new company is being set up to commercially exploit anaerobic digestion technology. As part of this work the company is working with North Wyke Research and Exeter University. The group is looking for an enthusiastic Engineer / […]Read More
How very sensible of you to recommend trams as the preferred solution for public transport in urban areas. I attach a note on the potential for integrating waste recycling with ultra light trams. If really good tram networks are installed (and the cost of installing lightweight rail has now been brought below £2 million per route kilometre double track) then, together with pedestrianisation, cycling and rickshaws, urban mobility can be brought to a very high level before having to bring in a few electric taxis.
Unfortunately I cannot get any of the relevant Departments in Government even to discuss these proposals, although Jonathon Porritt has now volunteered to take up the issue. I attach a copy of a letter to Hoon which still awaits a reply. The programme I am suggesting could easily be funded from a progressive transfer of money from the so-called Bus Service Operators Grant which spends some £400 million a year in subsidy to reduce the cost of fuel for diesel buses! The waste needs to be recycled urgently to prevent methane emissions to the atmosphere and to take some of the strain off landfill.Read More
Dear Claverton, Trading Green is moving forward and this might be a good time to ask for your assistance! As you will see by the attached, the main product we have started introducing to South-East Asia (Thailand and Philippines for the moment) is an innovative wastewater bio-treatment. Its superior performance and quick action can really […]Read More
