"Green" technologies cover an exceedingly wide spectrum, beyond wind and solar of course, to include biofuels, gasification of wastes, biomass-to-energy - - and even cleaner-coal and nuclear (e.g. SMRs) can be considered as greener. LINK not only understands the various technologies and the relative sustainability of each from a life-cycle perspective, but also has hands-on experience.
LINK has focused its efforts on a broad array of energy facilities and technologies over the past 15 years, and has provided millions of manhours of operational services to energy facilities. Solving the world's energy problems is likely one of the dominant issues facing us today. LINK is committed to being part of the Smart Solution, and we remain involved across the spectrum of alternative energies including biofuels and Small Modular Reactors, we are additionally focused on the energy efficiencies that can be gleaned from cogeneration and trigeneration as well as insulation as an important aspect of the smart solution.
Biodiesel (mono alkyl esters) is a cleaner-burning and diesel fuel made from natural, renewable sources such as vegetable and animal oils. It has a very high energy balance of between 3.4 and 4.5 (depending on the feedstock used), compared to corn-based ethanol with approximately 1.3 and petroleum (mineral) based diesel of 0.86. Biodiesel also emits a fraction of the carbon and other pollutants when compared to mineral diesel. Although there has been considerable criticism of corn-based ethanol, we view it as a transitional fuel that will be eventually replaced by cellulosic ethanol and possibly algae-based biodiesel. These biofuels have the potential to displace all petroleum based transportation fuels while dramatically reducing carbon emissions.
Link was awarded a project to assist in the development and planning of a large cellulose-to-ethanol project using a strong-acid approach on Municipal Solid Waste feedstock. Link was also awarded EPC oversight (including pilot projects for particularly troublesome sub-systems), commissioning and long-term operations contracts for the yet-to-be-constructed plant. The complex plant included MSW sorting, drying, hydrolyzation and cellulose conversion, acid recovery, fermentation, and distillation. The plant utilized dried sewage sludge converted to steam via a fluidized bed boiler, and had several profitable byproducts such as typical MSW rejects (e.g. aluminum), CO2, soil treatment, and green fuel. Link’s assignments during the project period included oversight of the prime EPC contractor during engineering and procurement; Link’s prime focus was the constructability and the operability of the processes and systems. Link also, in joint effort with Kvaerner, developed all O&M policies and procedures for plant equipment and systems
