Samuel Carrara holds a Master Degree cum laude in Mechanical Engineering (Major: Energy and Mechanical Plants) and a PhD in Energy and Environmental Technologies, both from the University of Bergamo.
After working as an engineer in the gas turbine field, he is now junior researcher at FEEM. His main research interests include renewable energies, sustainable development, energy policies, climate and energy economics, advanced energy systems.
We explore the operations, balancing requirements, and costs of the Western Electricity Coordinating Council power system under a stringent greenhouse gas emission reduction target. We include sensitivities for technology costs and availability, fuel prices and emissions, and demand profile. Meeting an emissions target of 85% below 1990 levels is feasible across a range of assumptions, but the cost of achieving the goal and the technology mix are uncertain. Deployment of solar photovoltaics is the main driver of storage deployment: the diurnal periodicity of solar energy availability results in opportunities for daily arbitrage that storage technologies with several hours of duration are well suited to provide. Wind output exhibits seasonal variations and requires storage with a large energy subcomponent to avoid curtailment. The combination of low-cost solar technology and advanced battery technology can provide substantial savings through 2050, greatly mitigating the cost of climate change mitigation. Policy goals for storage deployment should be based on the function storage will play on the grid and therefore incorporate both the power rating and duration of the storage system. These goals should be set as part of overall portfolio development, as system flexibility needs will vary with the grid mix.
Daniel L. Sanchez is a Ph.D. candidate in the Energy and Resources Group and a researcher in the Renewable and Appropriate Energy Laboratory at the University of California-Berkeley. He is interested in quantitative analysis to inform public policy, focusing on bioenergy and climate policy. His current research focuses design, deployment, and commercialization of bioenergy with carbon capture and sequestration (BECCS) technologies. Daniel has previously held positions with the Advanced Research Projects Agency-Energy (ARPA-E), Green for All, and the California Public Utilities Commission. He holds an M.S. in Energy and Resources and a B.S.E. in Chemical and Biomolecular Engineering from the University of Pennsylvania.
I am working on my MS/PhD at the Energy and Resources Group (ERG). My research is in low-carbon (low-impact) energy systems and economic development, modeling high renewable energy future scenarios, and deploying sMArt Grid (high-tech/low-cost) pilots in the rising south. I’ve worked in Chiapas (Mexico) developing regional microcredit schemes and river survey studies, designed and built ‘low-tech/high– impact’ water distribution systems for small communities in Uganda and Honduras, have used GIS models and InVest (Integrated Valuation of Environmental services and Tradeoffs) to study the hydrology of the Linthipe Basin (Malawi), and investigated linkages between hydrological variability, energy use, and agriculture in Punjab and Telangana (India).
My current work is in Nicaragua developing and building scenarios for the SWITCH model – optimizing the penetration of renewable energy into the country’s electric power system, and deploying the country’s first micro-scale demand response program (DR) through the use of ‘flexible energy toolkits’.
