New research from the Netherlands showed that renewable energy sources and storage in the short term can meet around 92.5% of European electricity demand in future energy scenarios, whereby the remaining 7.5% is paid by green hydrogen. The scientists considered Europe to be fully self-sufficient with zero import export of strength or hydrogen, with each of the 37 countries in the modeling a self-supply percentage of at least 80%.
Researchers from Utrecht University in the Netherlands claim that almost all energy demand in Europe can be paid by solar PV and wind energy, whereby the shipping hydrogen is only needed for a small part of the total demand.
They also discovered that overbuilding renewable energy capacity and “proactive” limitation would offer the energy system of the continent sufficiently strong power to manage intermittency of clean energy. Their analysis is based on the concept of the ‘firm kWh premium’, which they define as the ratio of a sturdy KWH’s Levalized Cost of Electricity (LCOE) and the LCOe of a ‘non -restricted’ renewable kWh. It is intended to measure the relative costs from converting renewable energy into company power.
The scientists also introduced a distinction between “sturdy LCOe” consisting of all generation and storage technologies and “non -restricted LCOE”, including only “non -cut” solar pv and wind energy. “To analyze the cost premium of converting intermittent renewable power into Europe, we compare multiple scenarios with different technology mixes, including Zonne -PV, onshore and offshore wind, battery storage, electrolysis and existing hydropower and nuclear capacity,” they explained further.
The research team has developed a model to assess the lowest annual system costs of the European energy system, the Pan-European intermittent renewable overview and defendant optimization model (Peirocom). It is said that it is said to be the installed capacity and shipment of all selected technologies at the same time, whereby the system must match the demand for electricity every hour and the annual hydrogen demand every year.
The academics considered Europe to be fully self-sufficient with zero import export of electricity or hydrogen, with each of the 37 countries in the modeling a self-supply percentage of at least 80%. They also adopted an efficiency of 95% for all high -voltage change flow (HVAC) and high -voltage direct current (HVDC) interconnections.
The proposed scenario also included 50 market junctions, 120 Solar PV nodes, 121 onshore wind nodes, 56 offshore wind nodes, 109 HVAC connections and 51 HVDC compounds.
The group has also considered six scenarios: a basic scenario in which solar and wind work in combination with lithium ion storage; a basic scenario with wind, solar energy, storage and hydrogen; two scenarios dominated by renewable energy sources, including current nuclear and hydropower capacity; a renewable scenario where hydrogen turbines are used for generating electricity generation; And a scenario including electrolyzers and hydrogen gass curbs.
“These six scenarios illustrate that although overbuilding and restriction will considerably reduce system costs in a system for renewable energy sources, a schedule only renewable energy sources is more expensive than a grid with a sort of shipping capacity,” the researchers emphasized.
Their analysis showed that renewable energy sources and storage can meet around 92.5% of the European electricity demand in the short term, whereby the remaining 7.5% is paid by green hydrogen.
“In limiting renewable energy sources, it is necessary to optimize system costs in a fully renewable electricity grid,” they explained. “In contrast to earlier research, however, we show that considerably less restriction is required when sufficient demand response and seasonal storage are available.
It is expected that hydrogen creates a considerable demand response capacity, while afterwards created guest turbines can help with the use of hydrogen during periods of lower generation of renewable energy sources. “We prove that this system is cheaper and robust, because it can handle a greater variety of weather patterns for several years,” the academics concluded.
Their findings can be found in the newspaper “Sturdy wind and solar photo photovoltaic power with proactive disability: a European analysis“Published in Energy conversion and management.
