Hydrogen Storage
The complication, until now, was storing enough Hydrogen safely to solve the cyclic nature of renewable energy generation - solar, wind, hydro. The safest way to store hydrogen is as a solid, or low pressure gas not liquid or high pressure gas. Storing as a solid is also, by far, the densest way to store Hydrogen.
H2G have solved the energy density challenge by Storing Hydrogen in Metal Hydride (FeTi or LaNi) Pellets. Hydrogen forms a safe solid as a Hydride, and like low pressure hydrogen gas, is at a safe low pressure, 100% recyclable, has no degradation or capacity loss.

Frequently asked questions
General
Hydrogen
Autarchy, also spelled as autarky, is the German word for Autonomy and which is often applied to Off-grid or Standalone systems that are fully independent of Grid Connection.
One bar is equivalent to 100kPa and is commonly used to measure atmospheric pressure as well as the pressure of gases in industrial processes. The Solid State Storage system for Hydrogen operates at around 40 bar which is considered a fairly safe operating pressure. Hydrogen Gas is generally stored and very high pressures that range from 350-700 Bar in order to obtain the required amount of Hydrogen in a reasonable sized cylinder. High Pressure Hydrogen Storage comes with far greater level of complexity when it comes to safety and increased levels of expertise and cost associated with very high pressure Hydrogen compressors.
Hydrogen is Scientifically shortened as H2 and is a colourless, odourless, and tasteless gas. Because H2 is lighter than air, it hovers higher than the earth’s atmosphere. Therefore, it cannot be found in nature and must be created by humans. Hydrogen is produced by separating it from other elements and collecting the vapour.
Biomass refers to organic matter derived from living or recently living organisms that can be used as a source of energy. Examples of biomass include wood, agricultural crops and residues, municipal solid waste, and animal waste.
Biomass can be converted into various forms of energy, including heat, electricity, and liquid fuels, through a variety of processes such as combustion, gasification, and anaerobic digestion. Biomass energy is considered to be some what renewable because the organic matter used to produce it can be regrown or replenished.

Ferro-titanium is an alloy that is primarily composed of iron and titanium. It is produced by mixing titanium scrap and iron together and then melting them in a furnace. The resulting alloy has a high strength-to-weight ratio and is highly resistant to corrosion.
Fossil fuels are natural resources such as coal, oil, and natural gas that were formed over millions of years from the remains of ancient plants and animals. Fossil fuels are considered non-renewable resources, meaning that they are finite and will eventually be depleted. They are also a major source of energy for human civilisation, powering transportation, industry, and electricity generation.
An electrolyser, also known as an electrolytic cell, is a device that uses electrical energy to split water or other liquids into their component elements. Electrolysis is a chemical reaction in which an electric current is passed through a solution, causing the ions in the solution to move towards the electrodes and undergo chemical reactions.
In the case of an hydrogen electrolyser, the solution is typically water, and the electrodes are made of a conducting material such as platinum or titanium. When an electric current is passed through the water, it causes the water molecules to split into hydrogen and oxygen gas through a process known as water electrolysis. This process occurs as follows:
At the anode (+), oxygen gas (O2) is produced: 2H2O(l) → O2(g) + 4H+(aq) + 4e−
At the cathode (-), hydrogen gas (H2) is produced: 4H+(aq) + 4e− → 2H2(g)
Electrochemical refers to a process or device that involves the transfer of electrons between chemical species. In an electrochemical reaction, chemical energy is converted to electrical energy, or vice versa.

It involves minimizing the negative impact of tourism on the environment and local communities, while also providing social and economic benefits to those communities.
A fuel cell is an electrochemical device that generates electricity by converting the chemical energy of a fuel and an oxidant directly into electrical energy. Fuel cells are similar to batteries in that they generate electricity through an electrochemical reaction, but unlike batteries, fuel cells require a continuous supply of fuel and oxidant to operate.
Fuel cells typically use hydrogen as the fuel and oxygen from the air to generate electricity and water
A hydride is a chemical compound that contains hydrogen and one or more other elements, usually metals or nonmetals. Hydrides can be classified into two main categories: ionic hydrides and covalent hydrides.
also known as saline hydrides, are formed by the reaction of hydrogen with highly electropositive metals, such as alkali metals or alkaline earth metals. These hydrides typically have the formula MH, where M represents the metal.
A lattice framework is a type of structural framework made up of a network of interconnected structural elements, such as beams or rods, that form a repeating pattern. The lattice structure is characterized by its open, lightweight design, which makes it strong and stable while minimizing the amount of material needed. Hydrogen, when stored as a solid metal hydride requires the metal to be structured as a lattice therefore providing interstitial sites for the Hydrogen to occupy. Hydrogen molecules stored in this manner can store closer than they can be stored in their liquid form.
A lithium-ion battery (LIB) is a type of rechargeable battery that uses lithium ions to store and release electrical energy. LIBs are widely used in electronic devices such as smartphones, laptops, and tablets, as well as in electric vehicles (EVs) and renewable energy storage systems.
