New innovations in energy recycling are driving change

As Sweden’s large cities grow, the need for energy increases, at the same time as the amount of waste increases. With leading technology and solutions in energy recovery, E.ON offers circular energy supply that makes a difference even today. Stockholm County is one of Sweden’s fastest growing metropolitan regions with almost 2.5 million inhabitants. Growth means, among other things, that demand for energy is increasing. At the same time, the amount of waste is increasing. One of E.ON’s solutions to these challenges is located in Bro outside Stockholm. Sweden is the Silicon Valley of sustainability with leading technology and solutions for circular energy conversion. One explanation is that Sweden was early in expanding district heating, which today accounts for 65 percent of all heating in the country. E.ON has managed and developed that technology with the Högbytorp CHP plant, which offers energy recovery 3.0, says Anette Blücher, Director Energy Infrastructure Solutions Nordic at E.ON. In the Högbytorp CHP plant, energy is recovered from waste through incineration, to produce local electricity and district heating. The plant is a technically advanced proof of the possibilities of circular energy supply. Anette Blücher wants the residents to experience that even things that cannot be recycled are useful. In a sustainable society, materials must be reused as much as possible. From materials that for various reasons can not or should not be reused, we can ensure that the energy is recovered and used as electricity and district heating. In Högbytorp, we collect waste and ensure that it is incinerated, but we also take care of the residual products after incineration. For example, the metals in the ash are extracted and reused after incineration. Technology for carbon sinksThe expansion of district heating has been a strong contributor to the reduction of greenhouse gas emissions in Sweden since the 1990s, according to the Swedish Environmental Protection Agency. To reach the goal all the way, E.ON runs several research and development projects on carbon sinks, ie various techniques for binding carbon dioxide and removing carbon dioxide from the atmosphere. We work hard to reduce the CO2 we still emit. It is a challenge that we share with the industry, and the development is driven by several leading players. One possible technology is CCS, Carbon Capture and Storage, where carbon dioxide is captured directly during energy recovery, bound in and stored in the bedrock. Another exciting possibility is biochar, which in simple terms is organic material that is heated in an oxygen-poor environment and as a result forms a solid product with a high carbon content that can be returned to the soil. Today we see solutions, now it remains to find economic models for this extremely expensive technology, says Anette Blücher.Facts E.ON
