Green hydrogen refers to hydrogen gas produced through a process called electrolysis, using renewable energy sources such as wind, solar, or hydroelectric power. It’s called “green”” because the energy used in its production comes from sustainable and clean sources, resulting in minimal or no greenhouse gas emissions. The process of creating green hydrogen involves splitting water molecules (H2O) into hydrogen (H2) and oxygen (O2) through electrolysis. During electrolysis, an electric current passes through water, causing the water molecules to dissociate into their constituent elements: hydrogen and oxygen. The hydrogen produced in this way can be stored and used as a clean energy carrier in various sectors, such as transportation, industry, and power generation.”
Co-processing is a technology for reusing waste as raw material or fuel, mainly in energy intensive industries, where it combines material/energy reuse and the final disposal/destination of solid waste in a single operation. It can contribute to the conservation of natural resources by replacing conventional energy sources (i.e. fossil fuels) and other raw materials with energy and materials recovered from waste, as well as reducing the waste generated in the manufacturing process, and so its overall environmental impact.
Access to clean cooking is essential for leading a healthy and productive life. Clean cooking solutions comprise fuels and technologies that cause very little or no household air pollution. While the definition of ‘clean cooking’ varies, they all broadly include technical aspects (type of fuel, stove efficiency), environmental (exposure, ventilation, etc.) and social aspects (access). Various sources also define certain clean fuels based largely on their emissions of pollutants and greenhouse gases (GHG), including solar, biogas, natural gas, liquified petroleum gas (LPG), ethanol-based fuels. Other measures include other multi-dimensional factors, including exposure, fuel efficiency, safety, convenience, affordability, and availability. The focus of this solution is renewable sources and enablers that can be used for clean cooking, excluding fossil fuels such as natural gas and LPG that might meet the definition of clean cooking, but are not renewable.
Solar photovoltaic (PV) technology is an excellent option as an environmentally friendly alternative to fossil fuels, and will be a key technology in tackling the climate emergency since it exploits clean and renewable sources of energy.
Sector coupling is defined as the process of interconnecting power generating resources with energy consuming sectors such as the heating, transport, gas, and other. This is in order to economically optimize operations of the energy system and facilitate the integration of the intermittent renewables through enhanced energy system flexibility. There are two main strategies: first, through electrification by promoting electric mobility and replacing traditional heating systems with electric heat pumps, to use renewable electricity instead of fossil fuels. The second strategy is through “Power-to-X”, whereby synthetic fuels are produced from renewable electricity through transformation into heating (P2H) or cooling, gas (P2G), or liquid (P2L) for use in final consumption. The generated fuels and carriers such as hydrogen, methane, gasoline, or kerosene can also reduce CO2 emissions using the existing gas and heat infrastructure.
