Nearly all hydrogen - 95% - is produced by fossil fuels, which release 70-100 million tonnes of CO2 every year. According to research, renewable energies could supply a substantial part of the European energy mix in 2050, of which hydrogen could account for up to 20%, notably 20-50% of energy demand in transport and 5-20% in

Renewable energy comes from unlimited, naturally replenished resources, such as the sun, tides, and wind. Renewable energy can be used for electricity generation, space and water heating and cooling, and transportation. Non-renewable energy, in contrast, comes from finite sources, such as coal, natural gas, and oil.

Hydrogen is one of the leading options for storing energy from renewables and looks promising to be a lowest-cost option for storing electricity over days, weeks or even months. Hydrogen and hydrogen

Renewable energy (or green energy) is energy from renewable natural resources that are replenished on a human timescale. Some may produce and export green hydrogen, although electricity is projected to be the dominant energy carrier in 2050, accounting

The expansion of renewable hydrogen use, emissions-free heating in buildings, and electric vehicles requires an integrated approach, connecting the utilisation of all renewable energy technologies. Policy makers should focus on implementing long-term plans for whole-economy decarbonisation and implement incentives reflecting the requirements of

Generating a clean hydrogen future. Demand for hydrogen reached 94 million tonnes in 2021, containing energy equal to about 2.5% of global final energy consumption, up from a pre-pandemic total of 91 Mt in 2019, IEA figures show. While most of the increase came from dirty sources, there are signs of positive change on the

The production of Green Hydrogen using renewable energy sources like solar, wind, and hydropower can provide energy security, reducing dependence on fossil fuels and ensuring a stable and reliable source of energy. Green hydrogen can also be produced locally, reducing the need for costly and environmentally damaging imports.

This brief provides an overview of the concept of power-to-hydrogen (P2H2) and its role in increasing the share of renewable energy in the power sector. P2H2 can provide grid balancing services and long-term storage to manage the variation in power supply from wind and solar photovoltaic (PV) technologies.

The policy framework was complemented with 2 delegated acts, formally adopted in June 2023, applicable to renewable hydrogen under the Renewable Energy Directive. The first one covers renewable fuels of non-biological origin (RFNBOs) and sets the criteria for products that fall under the ''renewable hydrogen'' category.

Renewable hydrogen is created by using electricity to split water into hydrogen and oxygen through a process known as electrolysis. The hydrogen is collected and used, primarily in industry, while oxygen is released as the by-product or captured for use by others. As we use electricity created from renewables, the process is carbon-neutral.
