Subject to Contract:

A significant finders fee, which could be as much 10s of £thousands, (subject to contract, site suitability etc) when and if building is commenced, and with significant interim payments as various hurdles (planning, connection etc) are passed, is offered for information leading to the identification of sites suitable for power plants fuelled / driven by / utilising: Read More→

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 scrubber (http://www.ergapc.co.uk/vtex.htm) which has the ability to scrub tars and particulate from the gas stream without clogging, and at the same time, to cool the gas reducing its moisture content so it is conditioned for use in the engine.

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,

While renewable energy is one of the most environmentally responsible courses for consumers, the same technology which provides green power can be profitable as a traditional power source as well.

Renewable energy portfolios are being mandated worldwide resulting in comfortable returns on $.12 USD/ kW and more on $.15 USD/ kW green energy programs.  However, a large number of remote operations are paying more than double that amount for standard energy rates.

$.12/ kW electrical rates can result in more than $250,000 net profit, before capital, interest and taxes, on a simple 500 kW power plant with less than 5 year payback. As the power generation rate increases the net return increases more than linearly due to economies of scale with equipment and labor.  This results in significant returns for modest sized renewable energy power plants producing “Green” power.

Even considering the social and environmental impact of green power, traditional power sources can supply power to projects which are willing and able to pay $.25/ kW with substantial returns to project owners.  At this power rate a 500 kW project will net more than $800,000 USD annually with a 2 year payback.

The keys to making these projects profitable are the site, power purchase agreement, fuel supply and power technology. 

Gasification is the combustion of biomass fuel in an oxygen deprived environment which produces a combustible gas.  Since a wide variety of fuels can be used in the power production process the systems can be part of a landfill diversion program, fire damaged forest remediation, biomass recycling using manures, rice hulls, food processing waste and other economical sources of clean fuel.

Since the producer gas from this system is consumed by a power generator there are very little emissions exposed to the open air.  While typical BTU content of the gas produced is less than propane it still provides a combustible fuel for various generator styles.  These include many types of reciprocating engines as well as turbines of all sizes.

Power generation projects can be designed to provide automatic feeding, operations and ash cleanout.   Remote monitoring of operations can supplement the local operators’ skills and enhance performance.  These features enhance the attraction of the system for remote sites as well as locations with limited skilled labor available.

1 kg of dry fuel can be expected to produce 1 kW of electrical output with enough surplus heat to distill 10 gallons of clean water.  The technology provides for several human needs.  It can supply heat, clean water, electricity, human sanitation and economic development.  When the fuel can be waste products from other activities we find that human habitation supplies much of the fuel itself.

Typical equipment costs of $2400 per kW fully installed are available.  Economies can be achieved through local sourcing of some of the equipment.  Power plant sizes can be from 5 kW to 1 MW in modular components.  Larger systems can be engineered as needed.

By increasing options for power production equipment at various levels of electrical output the gasification technology becomes the most flexible and economical of currently available systems worldwide.

Only about 1/7th of China’s vast area is suitable for agriculture due to desertification occasioned by overgrazing.  This has been going on for thousands of years, and was the reason for the Mongol hordes invading Europe (they got as far as the gates of Vienna, and right up to Poland)

Desertification is a huge and tabooed subject in China, and sand dunes are threatening to engulf Peking at some point not too far away.

As desertification continues, and more arable land is destroyed, and China’s demand for food grows, this leads to deforestation being exported to eg the Amazon to grow the soya beans to feed cattle for the Chinese.

This article describes a novel concept using existing technology to very quickly a) control the desertification and sand drifts b) enable the establishment of plant species and associated carbon sequestration in improved soils c) the construction of wind farms or CSP connected to Europe by either a lengthy HVDC transmission system, or the local production of ammonia which can readily be transported to eg Europe / USA and easily used as a vehicle fuel d) the construction of a vast area of seawater greenhouses using sea water pumped thousands of miles to be desalinated by solar energy to allow the production of food and or energy crops. (Contrary to what some ill-informed people claim this does not use a huge amount of energy compared to other national uses)

The concept  described is ADRECS – Aerially Delivered Re-Afforestation And Erosion Control System which can be applied in any desert area but in particular to the Gobi and other deserts in China which have  extremely serious potential effects on world food.

The ADRECS proposal claims to address this issue and the rough calculations show that using standard freight aeroplanes and heavy lift helicopters, the installation could be achieved in a matter of a decade.
