SRE Renergi technology captures the energy content in warm flue gases, instead of simply releasing this as waste heat from heat plants fired with green biomass. By increasing the surface available for heat exchange several fold, with the aid of very tiny water drops, and leading moist flue gases across this surface, the Renergi system cleans the flue gases and increases energy efficiency by 25-30%. This means a 25-30% reduction in carbon dioxide, near particulate-free emissions, reduced sulfur emissions, and reduced odor. Their intelligent manufacturing process has cut costs providing the end-user with a pay-back period of two to three years. They currently market a standardized range of products for boilers between 1.5 and 30 MW.
With SRE Renergi, the energy efficiency of a biomass-fired heat plant increases by 25-30%, significantly improving its competivieness relative to fossil-fueled power plants. The system is particularly suited for regions with heating needs and a good supply of forestry products, and which are structured to allow for district heating systems. District heating implies large climate benefits. In Växjö, Sweden, emissions per person were reduced by 30% between 1993 and 2006, mainly due to switching to district heating. Now the goal is freedom from fossil fuels altogether. If biomass-fired heat plants producing 50 TWh heat energy—equivalent to the production in Sweden today—were to use Renergi, the same amount of biomass as used by those plants could instead yield 65 TWh and reduce the end user’s need for complementary electric
The technology can also be used for generating power on board large ships. This would reduce fuel consumption by 5-10% and reduce both CO2 and NOx emissions. Today, there are roughly 90 000 ships above 100 tons and another 20 000 military ships equally large; their combined capacity is 450 000 MW. According to estimates, international shipping uses 289 million tons of fuel annually and emits roughly 920 million tons of carbon dioxide. If Opcon Powerbox were used to reduce fuel consumption by 5-10% on board one-fifth of these ships, this would cut emissions by 9-18 million tons of carbon dioxide. NOx and SOx particulate emissions would be cut too, as would be emissions of hydrocarbons. The climate benefits from these innovations would amount to 94 million tons per year, as much as the total sum of emissions from Israel and Peru.
