64 Cyprus Energy Regulatory Authority Integration of innovative green technologies on existing public transportation buses for 5% to 30% fuel savings (BUSFUELSAVINGS) The BUSFUELSAVINGS project is part of the RESTART 2016-2020 programs of the Research and Innovation Foundation for Research, Technological Development and Innovation. The public transport of Cyprus consists of 2600 buses, which consume approximately 60,000,000 liters of diesel per year. High fuel consumption is a significant cost for transport companies struggling to survive through government subsidies. Additionally, the massive use of diesel causes environmental pollution with all the negative effects on the quality of life of society. The aim of the BUSFUELSAVINGS project is to reduce this problem by reducing bus fuel consumption by 5-30 % and reducing exhaust emissions (particles, unburnt hydrocarbons, CO2, CO, NOx) by >20 %. The only possible way to achieve this goal is to increase the engine efficiency of existing buses by integrating on existing engines an innovative, green technology, such as the HHO gas generator. This a project of large-scale and multidisciplinary collaboration, which aims at enhancing the effectiveness of the Research, Technological Development and Innovation system and the interconnection with the productive base in transport. It is expected to bring concrete results to strengthen the competitiveness of the economy and will have an impact on economic growth and quality of life. It will, also, create new businesses and jobs that are expected to contribute to address the unemployment. In 2021, CERA was an active participant in all the consortium meetings and at the BUSFUELSAVINGS technical meetings. Storage and Renewables Electrifying Cyprus (SREC) The SREC project is part of the RESTART 2016-2020 programs of the Research and Innovation Foundation for Research, Technological Development and Innovation. The project was finalized in November 2021. All the objectives of the project were successfully achieved. Energy storage is a methodology that necessarily accompanies the conversion and use of energy from renewable sources. It is a significant parameter in the effort to increase the share of RES injected into the networks. In isolated networks, such as the one in Cyprus, the need for storage is a high priority for reasons of security of supply, utilization of infrastructure, inflow of RES, reduction of emissions, domestic added value and sustainability. The purpose of the SREC project was the development and implementation of a regulatory framework that permits the operation and inclusion to the network of storage projects as well as the positioning and licensing of 2 medium-scale storage projects. Having regard to all the important operating parameters of the electricity network and the existing power plants, an algorithm was developed to simulate the effects of various storage - hybrid power plants scenarios that are applied to the independent network of Cyprus. The main areas of the project that have been completed are: • Selection of most appropriate storage technologies according to scale and application. • Selection of hybridization storage technologies with RES and conventional power production plants for effective and innovative combinations. • Development and testing of dynamic simulation models for the proposed technologies. • Use of dynamic simulation models to conduct various studies on the dynamic efficiency of electricity systems and analysis of the dynamic behavior of the proposed technologies and their
