New article on integrating renewables with Power-to-Hydrogen seasonal energy storage, published in Applied Energy
Energy storage is vital for integrating renewable energy. Already for urban distributed energy systems, off-the-shelf technologies consisting of renewables, heat pumps, along with batteries and hot water storage can reduce CO2 emissions by 90% cost-effectively.
In this Download article, the interdisciplinary team of Evan Petkov (SusTec) and Paolo Gabrielli (ETH Zurich - Institute of Energy and Process Engineering) analyze the factors leading to the deployment of Power-to-Hydrogen (PtH2) within the optimal design of district-scale Multi-Energy Systems (MES) utilizing an optimization framework and comprehensive techno-economic uncertainty analysis. When the sun doesn't shine and the wind doesn't blow sufficiently for a long period of time, traditional storage options are not the best solution for maintaining a reliable low-carbon energy system.
Enter the role of Power-to-Hydrogen as seasonal energy storage – the emerging technology is ready to play a key role to reduce emissions to ZERO. This powerful technology is able to offset the long-term mismatch between renewable generation and energy demand particularly in colder regions.
Technology ready, policy pending - with storage deployment accelerating around the world, policymakers need to alleviate barriers for adoption of NET ZERO distributed energy systems.
