Biomass Gasification and Boilers

Our latest addition to the Green Energy Solutions portfolio are Biomass Gasification and boilers. For this area, we work with a strategic partners with vast international experience. Biomass includes a wide range of materials including energy crops and agricultural sources.  Gasification helps recover the energy locked in these materials. Gasification can convert biomass into electricity and products, such as ethanol, methanol, fuels, fertilizers, and chemicals. Biomass gasification plants differ in several aspects from the large-scale gasification processes typically used in major industrial facilities such as power plants, refineries, and chemical plants.

Our strategic partner for this area is Tigre Energy. With their strong backing, we provide renewable energy solutions for clients who need low carbon, sustainable power, either for themselves or for export to other users and the grid. Supplying proven, modular biomass conversion technology, suitable for a variety of biomass or waste-derived fuel feedstocks, Our expert team and associates can assist with every aspect of your project. Increasing demands for renewable energy, worldwide, have led to the development of ultra efficient systems and our team has focused on the latest generation of thermal processes, with technologies capable of generating quality synthesis gas to directly run engines, generate power or replace natural gas applications. Strong links with our chosen technology developers and specialist engineering partners provide our clients with a safe and seamless transition from concept to delivery.

Tigre Energy was established in 2012 by Phil Scowcroft, one of the most experienced UK professionals in the gasification and "energy from waste" sectors. Many years of direct experience with advanced thermal processes means that Phil and his team are well placed to identify the best technologies available and to assist clients with their implementation. "Only a few technologies, out of dozens in this sector, have the ability to demonstrate reliability and efficiency, despite the inflated or erroneous claims of many", states Phil.  "Tigre can work with the client and the technology provider to deliver a project which is professionally managed and avoids learning lessons the hard way".

Small-scale biomass or "waste to energy" projects have traditionally seemed too large, complex or dirty to be considered suitable for siting on the client's site, especially where the core business is not in the waste or environmental sector. Tigre works with Otto Simon and the technology provider to deliver a neat, packaged CHP plant which would not look out of place on any modern business park and can be tailored to suit the client's needs and preferences. There are no pressure vessels, chimney stacks or unsightly tangles of pipework to consider, and the units can be placed adjacent to buildings in their own containerised housings, or located in purpose built facilities, as required.


By converting the biomass feedstock into a clean, high energy synthesis gas (Syngas), the modular unit is more of a recycling plant than a combustion process. The syngas burns extremely cleanly, and can be fed directly into a standard gas engine to generate both electricity and heat/cooling. This technique maximises the financial incentives available under the Renewable Obligations, enabling projects to benefit from very fast paybacks. At the same time it reduces the scale and complexity of the plant.......and the capital cost! Built and tested at the factory, these units can be shipped and assembled in a matter of days.

Each modular unit produces 1MWh of electrical power (0.9MWe net) and up to 1.4MWh of heat, available for space heating, process hot water/steam or chilling/cooling via absorption chillers. Typically, a 1MWe unit will utilise about 1 tonne/hr of biomass fuel. A modest fuel store is required in order to store sufficient material to run the plant, normally allowing for 2 or 3 days requirement. The gas engines can be upgraded to "dual fuel" engines if required. This means that syngas can be switched to natural gas, if required. Where power generation is absolutely critical, this can be a useful back-up. The only bi-products are a small volume of dirty water, from the gas clean-up unit, and an amount of bio-char (charcoal) which has a positive market value, for example as a soil conditioner.

Waste and Recycling companies may have waste wood or other biomass materials available in large quantities. Regularly, they have a high power demand, to run a MRF or recycling business. SRF and RDF may also be available for future energy production. Paybacks for these types of projects can be rapid.

Manufacturers, processors, distribution centres, data centres and IT/Communications hubs often need lots of power and heating or cooling energy. Tigre can reduce energy costs and at the same time provide a secure and sustainable "renewable" generation plant, either on or adjacent to the client's site.

Small islands and remote areas often struggle to juggle their requirements for power generation and waste management. Tigre's modular approach can provide a self-contained and sustainable long term solution, with the units being fed by biomass or processed waste. Waste heat can also be used to dry the "waste" fuel, if required.

Developing and growing countries often have problems matching their energy generation with rapid growth. Many countries may have crop residues and bi-products ideal for use as a biomass fuel, right there on their doorstep. Bagasse, rice and peanut husks, palm kernel shells, tobacco dust and stems, olive pits.......these are just a few of the readily available fuels in some regions.
