This study explores the possibility of using the island''s indigenous renewable energy resources to secure energy supply for Sri Lankaʼs power, heat,
heat pump. This work proposes a new Pumped Thermal Energy Storage (PTES) configuration that works with supercritical CO 2 as the working fluid and molten salts as the thermal storage fluid. The net work generated by this novel proposal is 12.46 MW in the load and 10 MW in the discharge, reaching an efficiency of 80.26%.

Evolution of electricity final consumption by sector in Sri Lanka since 2000. SVG. PNG. CSV. Source: IEA Data Services. Licence: CC BY 4.0. Sri Lanka''s primary energy supply is mainly generated by coal. However, 23% of the total energy consumed in the country comes from modern renewable sources, the most commonly used being hydropower.
As shown in Fig. 1 (d), pumped thermal energy storage (PTES) uses conventional heat engine cycles with the motor-compressor and expander-generator set to achieve the bi-conversion between electrical power and thermal energy by using a
6 · 3. Thermal energy storage. Thermal energy storage is used particularly in buildings and industrial processes. It involves storing excess energy – typically surplus energy from renewable sources, or waste heat – to be used later for heating, cooling or power generation. Liquids – such as water – or solid material - such as sand or rocks
The proposed 4 energy storage solutions for Sri Lanka include: Pumped Hydro Storage: An efficient and established method for large-scale energy storage. Battery

Integrated cooling heating and power model based on solar energy source and thermal storage tank and battery are presented in [13], to enhance energy efficiency and decrease the pollution. Also, the chaos-mutation-whale optimization method is suggested to solve the approaches based on chaotic initialization and mutation rules into
Decarbonization may require the efficient electrification of applications, like natural gas furnaces for space heating, that currently involve burning fossil fuels. The environmental consequences of such a fuel switch depend on location and time. Here we show that, in most parts of the U.S., a switch from natural gas to electric heat pumps
The purpose of Energy Storage Technologies (EST) is to manage energy by minimizing energy waste and improving energy efficiency in various processes [141]. During this process, secondary energy forms such as heat and electricity are stored, leading to a reduction in the consumption of primary energy forms like fossil fuels [ 142 ].
Compared to sensible heat storage, TES using PCMs not only shows a significant reduction in the storage volume [] but also enables the use of thermal energy at relatively constant temperatures []. PCMs are mainly categorised as organic, inorganic and eutectic materials, in which organic PCMs can be further classified as paraffins and non
In terms of climate vulnerability, Sri Lanka is among the 43 countries of the Climate Vulnerable Forum that have agreed to make their electricity generation 100 percent renewable by 2050 (71,505 GWh

MAN ETES is a large-scale trigeneration energy storage and management system for the simultaneous storage, use and distribution of electricity, heat and cold – a real all-rounder. Heating and cooling account for 48% of all global energy consumption and 39% of all CO 2 emissions – because only 10% of this energy comes from renewable sources.
This indicates significant potential for harvesting wave energy (Watabe et al., 2001). Amarasekara et al. conducted an electrical pre-feasibility study to assess the wave power generation
In May 2021, USAID greatly expanded this effort by awarding a $19 million energy project to help the Government of Sri Lanka make its power sector market-based, secure, reliable, and sustainable. The project will facilitate
Abstract Energy is the driving force for automation, modernization and economic development where the uninterrupted energy supply is one of the major challenges in the modern world. To ensure that energy supply, the world highly depends on the fossil fuels that made the environment vulnerable inducing pollution in it. Latent heat
