Green Heating and Cooling | Hydrogen
https://hydrogeneurope.eu/green-heating-and-cooling

Heating and cooling consume half of the EU's energy. Although this sector aims at being a clean and low carbon energy, 75% of the fuel it uses still comes from fossil fuels (nearly half from gas). The sector is based on a vast, European interconnected gas infrastructure which delivers the needed energy to heat homes in the EU.

If Europe wants to decarbonise heating and cooling it faces several options:
Through the electrification of heating with heat pump or electric heaters or via the introduction of renewable gas such as hydrogen or biogas.

The electrification options are feasible for a number of building (new builds only and that are well insulated and where low temperature heating through the floor is possible) but the majority of the building stock today is not compatible. Moreover, the demand of heat is concentrated in winter time when renewables are less available. Additionally, a complete electrification of heat would imply that the gas grid is no longer used and becomes a stranded asset.

...

There are three ways to decarbonise the gas grid: Green and Decarbonised Hydrogen:

* Green hydrogen through water electrolysis using renewable electricity.
* Decarbonised hydrogen through natural gas reformation with carbon capture and storage.
* By-product hydrogen taken from an unavoidable source of hydrogen which would have been otherwise flared or ineffectively burnt for electricity generation.

The gas infrastructure decarbonisation through the introduction of high share of such hydrogen, firstly through a blending with natural gas and in the future possibly to a complete conversion to 100% hydrogen system is a reality that needs to be acknowledged and pushed for.

Additionally, this enables a greater integration of renewable energy sources and a direct reduction of greenhouse gas emissions. Furthermore, due to the increased share of intermittent renewable energy sources (wind and solar) in the European energy system, the utilisation of the vast gas infrastructure as an energy storage asset is an opportunity (the green gas being used in homes but also in gas-fired power plants (link to sectoral integration).

Hydrogen represents the optimal overall solution for long-term, carbon-free seasonal storage.

Hy2green - Das Energiespeicher-System für natürliche Energiequellen : Hy2green

Hydrogen is generated from electrical energy by means of electrolysis and fed into storage tanks filled with metal powder. Here, the hydrogen enter into the metal structure and remains as a safe and stable compound – which is known as metal hydride. This compound can be released again by simply adjusting the pressure and temperature. The released hydrogen is fed into a fuel cell and converted back into electricity and heat. The only residues are oxygen and water – natural elements and no environmental pollution!

The integrated heat management system captures the conversion energy that is lost as heat and makes it available to the application’s heat cycle. This significantly increases the energy efficiency of the entire system.

The result: An efficient zero emission electrical and thermal power system.

...

The Hy2Green system covers energy storage ranges from 80 kWh to 66MWh and can be tailored to the application need. Its modular system approach offers a perfect integration of short term (day-night) storage types (e.g. electric batteries, hot water accumulators) enabling highest system flexibility.

IOM_NUKSO: chladna deviace je nad evropou, jinak globalne rekordni narust teplot o 0.2 C v dubnu

LINKOS: v Rusku za to asi taky můžou ekologové, muhehe

LINKOS: to se už děje, a ne, není to binární proces "je permafrost" x "není permafrost". Všechno asi nejbližší stovky/tisíce let neroztaje, ale to ani není potřeba, jen z z těch pár metrů co roztajou to může uvolnit metanu víc než dost. Kromě té Shakhove co to systematicky studuje posledních 10-15 let minimálně co se týče viditelných publikací ale k permafrostu a potenciálu kolik to může metanu uvolnit a jak masivní to je feedback loop se moc neví, protože systematických dat je málo. Proto to ani IPCC report prakticky nezohledňuje, protože nemá "dost tvrdá" data. (Nejsou data? Jev neexistuje.) Ale pokud ty locking patterny jetstreamu budou jako teď kdy nám tu měsíc v kuse prší a je relativně zima, zatímco na Sibiři mají měsíc v kuse třicítky vedra, tak se to tomu permafrostu líbit nebude. Nowaco bude mít ztrátu z toho že mu zhnijou mražení mamuti, co si tam archivuje.
