Diesel Fuel Storage & Deterioration Prevention

Diesel Fuel Storage & Deterioration Prevention

Treatment to prevent degradation of emergency diesel fuel storage Hi Dave, We wouldn’t advise that diesel fuel is stored for long periods of time, especially for emergency purposes, without a number of measures in place – I call it ‘fuel husbandry’. Diesel blends with a bio-diesel content, such as the EN590 spec that is used commonly around Europe and has bio content up to 7%, can be stored up to ... »

IEA Biofuels 2050 Roadmap (27% of transport fuel) – Press release 20apr11

  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 of its GHG-LCA graphs. For a couple of reasons, I find biofuels to be infer... »

gasification, biogas, mulching biochar

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 minutes up to 650degC then rapid quenching, c.30-40% char) S... »

Papers in Energy Policy from Mark Delucchi and Mark Jacobson, Stanford / California University USA – 100% renewable energy at reasonable prices and timescales

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 welcome comments on these papers. (Please do not distribute them system... »

Critique / comparison of bio fuels / jatropha / with other energy options – wind etc

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 windfarm would produce much more energy per sqkm ... »

Use of biofuels, biodiesel, bioethanol etc is it feasible, ethical, sustainable and environmental?

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 are sobering and illustrate for example the limited supply of milk and meat from  permanent grass pasture. ... »

Gasification gets The Guardian treatment

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 the underlying problems of the waste gases from the gasification processes described :- http... »

Biomass 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 ... »
