#Energy Research News

Making the EU Carbon Border Adjustment Mechanism acceptable and climate friendly for least developed countries

This week in #EnergyResearchNews, we highlight a paper that shows a different facet of EPFL research- the importance of policy in the energy transition. Sigit Perdana and Marc Vielle, researchers from the Laboratory of Environmental and Urban Economics, investigated how adding a carbon tariff to energy-intensive products imported into the EU affects Least Developed Countries (LDCs). By modelling the outcomes of different potential scenarios, the authors propose measures that will limit the harm done to LDCs while maintaining the environmental benefits of the tariff.

Photo-Electrochemical Conversion of CO2 Under Concentrated Sunlight Enables Combination of High Reaction Rate and Efficiency

Photo-Electrochemical Conversion of CO2 Under Concentrated Sunlight Enables Combination of High Reaction Rate and Efficiency Carbon dioxide is a very stable compound which makes it challenging to transform into other products. Researchers at the Laboratory of Renewable Energy Science and Engineering have developed a device that can turn carbon dioxide, water, and sunlight into solar fuels. The device is unique in that it works with concentrated light, at high production rates, and with high efficiency. The work is featured on this month’s cover of Advanced Energy Materials! Congratulations to authors Etienne Boutin, Mahendra Patel, Silvan Suter, and Prof. Sophia Haussener, as well as collaborators at the Janáky lab.

Design and Cost Analysis of 100 MW Perovskite Solar Panel Manufacturing Process in Different Locations

Not only is it important to invent new technologies for renewable energy, it is also critical to figure out the right path for how to manufacture them. Researchers from EPFL have investigated production models of perovskite solar cells to determine which material inputs, processes, and locations of manufacturing lead to the best chance of commercial viability and low energy payback times. An interesting, collaborative paper from the IPESE, GMF, and LCOM labs. Congratulations to all authors and collaborators!

Thermally controlled growth of photoactive FAPbI3 films for highly stable perovskite solar cells

Perovskite solar cells could revolutionize the solar energy field with their low cost of manufacturing, low weight, and high efficiency. Unfortunately, current perovskites suffer from low durability and often use toxic solvents in their production. Researchers at the Laboratory of Photonics and Interfaces have demonstrated a potential solution to these problems- the use of flash-infrared annealing method to create solar cells with robust stability. Beyond producing and testing an efficient device, they also look into the mechanism of how exactly it is formed.

An Organic Semiconductor Photoelectrochemical Tandem Cell for Solar Water Splitting

Researchers from the LIMNO lab at EPFL have demonstrated, for the first time ever, a way to split water into hydrogen and oxygen using organic semiconductors within a solar-powered photoelectrochemical tandem cell. Organic semiconductors are made from commonly available carbon-based materials, avoiding the need for expensive or difficult to obtain metals. This technology creates new possibilities for the production of green hydrogen. Congratulations to authors Dan Zhang, Han-Hee Cho, Jun-Ho Yum, Mounir Mensi, and Professor Kevin Sivula!

Optimal Co-Planning of ESSs and Line Reinforcement Considering the Dispatchability of Active Distribution Networks

Incorporating uncontrollable renewable energy sources like wind and solar into the electricity systems makes grid’s management significantly more complex. In this paper, researchers from the Distributed Electrical Systems Laboratory and ABB / Hitachi Energy Research present a method for how to best utilize distributed energy storage systems to address the intrinsic uncertainty of renewable energy production. They tested the effectiveness using simulations on a real Swiss electrical distribution network hosting substantial amount of renewable electricity generation.
