Using Biomass as a fuel is a positive benefit for the environment

Dear Richard   Thank you very much for this fantastic paper about the forest   I was asked if we also have this biomass debate in DK, yes we have, and  the same arguments. The Danish District association DanskEnergy, the association of power companies held a conference recently about it and concluded that biomass with the certificates was considered to be CO2 neutral Also the Danish Ener... »


Biomass fuels – critique of FOE report

Re. the FOE briefing on using woody biomass in power plant. It is dreadful, masquerading as ‘research’ when it is just a re-tread of the appalling ‘Dirtier than Coal’ report from 2012-13. This was based on very biased research by the US legal anti-biofuels ‘hired gun’ Tim Searchinger. This carefully selected amongst the worst out of 234 scenarios developed by DE... »

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... »

Adsorbed Synthesis Gas – light weight tankers for non fossil fuel shipping fuel

I am trying i to find a supplier of ready made -lightweight ro/ro tanktainers that will hold my own supply of clean syngas (no inerts) I make coconut shell activated carbon with high microporosity and hardness.  Alternately  am looking for someone who has experience working with ASG in particular- making portable tanks- also trying to work out the totals per M3 for capacity, fuel value . The gas w... »

Evidence of an imminent global oil crunch / peak oil has continued to build, un-noticed by the majority of people

Folks   In the run up to the UK election, evidence of an imminent global oil crunch has continued to build, un-noticed by the majority of people, almost entirely uncommented on in the election campaign. The CEO of a major oil company has admitted it no longer pays to build up new oil reserves. A US military panel has warned of dramatic shortfalls in oil supply by 2015. A senior US government offic... »

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... »

Hydrogen – the green currency of the future

All governments have pledged to improve energy efficiency and reduce carbon emissions; this effectively means that the world must move to: Electricity from nuclear, renewable or decarbonised sources Hydrogen from renewable or decarbonised sources biomass derived methane gas or hydrocarbon liquids or heat as a by-product, or from biomass, solar or geothermal sources. Of these electricity and ... »

"trams as the preferred solution for public transport in urban areas"

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, cycli... »
