CirclEnergy - Enabling a Circular Economy

The CirclEnergy project aims to reduce society’s dependency in fossil fuels by facilitating the expansion of CRI’s innovative Emissions-to-Liquids (ETL) technology.

In capturing industrial emissions and converting into green fuels and chemicals, CRI’s ETL platform is a key enabling technology for a transition to a circular economy in which maximum value is extracted from each carbon molecule. The same process has the potential to address key challenges to the integration of renewable energy sources into power systems and support energy transition in transport. The projects aims to achieve the following objectives:

Carbon Capture and Utilisation

More than 90% of global energy consumption is derived from the combustion of coal, oil and gas. A consequence of burning such quantities of fossil fuels is the emission of about 100 million tons of CO2 into the atmosphere each day. To compound the problem, activities such as deforestation decrease the availability of natural CO2 sinks and prevent the re-uptake of the CO2. To try to avert the risk of runaway global warming, catastrophic sea-level rise and a collapse of the marine ecosystem, experts attest that by mid-century fossil fuel derived energy needs to be replaced by renewable energy.  It is generally felt that to ensure its continued existence on Earth, it is vital for humanity to collectively progress beyond fossil fuel dependency and employ all means possible to mitigate the effects of CO2 in industries where fossil input remains necessary.

The ETL technology offers an alternative pathway for reduction of CO2 waste in energy dependent industries with minimal environmental impact while simultaneously reducing dependency on fossil fuels. In its process, inevitable CO2 industrial emissions are captured, purified and reacted with hydrogen produced through water electrolysis, to generate methanol. Hydrogen may also be processed from by-product streams of industries that produce more than they consume in some cases. The reacton takes place over a well-known copper/zinc oxide catalyst system. The methanol is produced in an aqueous mixture and must be condensed and subsequently distilled 99.5% w/w.

Renewable methanol

Methanol is a large platform clean fuel and chemical with multiple applications. Chemically identical to fossil methanol, renewable methanol can be substituted for any traditional methanol application and thus represents a low-carbon fuel and feedstock for synthetic materials. The ETL technology enables production of renewable methanol consisting of ultra-low carbon intensity, or a carbon reduction of more than 90% compared to fossil fuels, in the complete product life-cycle, from extraction, production to end use. The process is certified by SGS Germany according to the ISCC Plus system, based on standard ISCC EU methodology for calculation of GHG emissions in the product life-cycle.

A highly convenient transport fuel, Vulcanol is a clean burning, high octane fuel which offers a more efficient combustion than gasoline or diesel. It can be splash-blended with gasoline to significantly improve engine performance and vehicle carbon footprint. Vulcanol can be used directly in internal combustion engines with merely minor modifications, in fuel cells, turbines or boilers. It can be used for gasoline blending and production of fossil fuel components or biodiesel. It is also an optimal marine fuel, emitting low levels of NOx emissions, no SOx emissions and no particulate matter when combusted.

As a versatile, clean-burning fuel and chemical, renewable methanol could replace all forms of fossil transport fuels used today and significantly reduce the carbon footprint of various every-day life energy needs.

At its core, the ETL technology utilizes CO2 and hydrogen as raw materials to produce green methanol, an advanced fuel and greener substitute for conventional methanol, providing both economic and environmental benefits in industrial manufacturing and power generation.


Sustainability is integral to the ETL technology. ETL production plants require no arable land, cause no greenhouse gas emissions and form no toxic by-products.


Scalability is a key ETL feature. Plant designs can be tailored to reflect feedstock availability of various applications, encompassing within their scope industrial manufacturing of different calibres.


Operational flexibility allows the ETL system to work with fluctuating electricity supply and heterogeneous feedstock sources.


Inherent profitability, based on proven upstream costs and and downstream offtake prices supported by global trends, is attainable to ETL adaptors.
