Chemrec route most energy- and cost efficient in RENEW study
The Chemrec process to convert biomass to motor fuels based on black liquor gasification has the highest conversion efficiency, the lowest product cost and the highest green house gas emission reduction amongst the studied processes in the RENEW project. The Chemrec process is also one of two recommended for demonstration in industrial scale.
The report states that demonstration on a commercial scale of the most advanced BtL concepts is of utmost importance and that the Chemrec process is ready for such a demonstration.
Biomass-to-liquid for climate protection and supply security
One of the main drivers for BtL fuels is climate protection and the potential for achieving a reduction in greenhouse gases emissions. The Chemrec process reduces CO
2
emissions by 95%, also best in the study, while simultaneously increasing security of fuel supply. The evaluated Chemrec process is designed as an integral part of a pulp mill and produces an environmentally friendly, carbon-neutral diesel fuel, DME (dimethyl ether).
The efficiency is high due to a shift to more advanced technology in the energy and chemical recovery area of the pulp mill and the high efficiency achievable in DME and methanol synthesis. In the process biomass is converted to BtL fuels utilizing a highly concentrated liquefied biomass stream in the pulp mill, so called black liquor. The process uses locally available biomass not competing with food production.
– Countries with a high concentration of pulp production sites, thus having a high potential for Chemrec BtL plants, include USA, Canada, Japan, Brazil, Sweden, Finland and Chile, says Patrik Löwnertz, VP Marketing and Sales.
With the Chemrec process it is possible to produce an advanced biofuel at a cost equivalent to €0.5/l diesel equivalent.
The Chemrec technology ranks at top for energy efficiency and primary product yield.
