The unprecedented pace of technological progress is transforming our society, but is also driving an ever-growing demand for electrical energy. Meanwhile, The UN Sustainable Development Goal 7 pushes toward a future where everyone, everywhere, has access to clean, affordable, and reliable energy. This calls for cleaner production and conscious use of sustainable energy. Addressing this challenge of a sustainable energy transition is vital for the future of our society. A key factor in this regard is the efficiency of electrical networks. An efficient network, with minimal losses, enables innovations such as smart grids and the integration of renewable energy sources.

As the need for climate change mitigation intensifies, a crucial challenge emerges: how do we tackle the menace of carbon dioxide emissions? One promising solution is Carbon Capture and Storage (CCS), a technology by which carbon dioxide emissions are captured and stored deep underground in rock formations or depleted oil wells. While CCS holds significant potential for curbing industrial contributions to climate change, it demands suitable underground storage space for the captured carbon dioxide, which is accompanied by two major hurdles. First, identifying these locations is challenging because storing carbon dioxide requires special geological conditions underground. Second, this may give rise to “Not-In-My-Backyard” protests in communities that host carbon dioxide storage projects due to public misperceptions of carbon dioxide as toxic for individuals.

As climate change accelerates and CO2 emission reductions alone prove insufficient to meet climate targets, carbon removal has become essential for tackling hard-to-abate emissions. However, deploying carbon removal at scale presents a critical challenge for governments: How can they ensure it is both effective and affordable enough to secure public support? We show that this public support challenge can be overcome if carbon removal practices are deployed in combination with regulations that enhance the durability of CO2 removal , even if these regulations increase costs.
The publication of RESPONSE fellow Katrin Sievert shows that costs of removing large quantities of CO2 from the air will fall in the medium term, but not as much as previously hoped.
In multi-energy systems (MES), different energy carriers such as electricity, heat, and gas interact with each other. When optimally designed and operated, MES can outperform energy systems without sector coupling in terms of economic, environmental, and social sustainability. MES can thus contribute to the transition towards affordable, low-carbon and secure energy.

Navigating the complexities of bioenergy, its potential for carbon neutrality, and its conflicts with land, food, and feed resources is a pressing issue. What if we could circumvent these issues and focus solely on land-free bioenergy, similar to growing mushrooms on waste coffee grounds for a delicious dish? Waste and byproducts can generate valuable bioenergy, playing strategic roles in a future sustainable energy system.
The ETH Energy Blog post of RESPONSE fellow Fei Wu presents key findings from our latest research papers, providing insights into the strategic applications of land-free bioenergy and its policy implications. Join us in exploring the ‘why,’ ‘what’, and ‘how’ of deploying land-free bioenergy effectively in the quest for carbon neutrality.
