Green Hydrogen
Since 2007, one of Avapa Energy partners has been involved in research on hydrogen energy storage.
Green hydrogen can help integrate more renewables, decarbonize hard-to-abate sectors like steel, chemicals, trucks, ships, planes, and enhance energy security through its capability to be stored and re-used.
According to a recent McKinsey report, green hydrogen will reach cost-parity with LNG before 2035 and green hydrogen volumes will increase five-fold by 2050.
The European Community is actively promoting the substitution of fossil gases with green hydrogen, with a target of reaching net-zero by 2050 (https://energy.ec.europa.eu/topics/energy-system-integration/hydrogen_en).
Avapa Energy has designed two electrolyser plants and is currently working on their planning and permitting:
-
A 10 MW PEM stack electrolyser coupled with a medium pressure compression station and a 2-day compressed gas storage for a daily production of over 4.000 kg of green hydrogen. The plant is designed for a direct connection with a nearby industrial facility and is energized by a large-scale photovoltaics plant.
-
A second hydrogen plant, with same capacity and daily productions, will feed a medium pressure compressor and a further high-pressure compressor stage to fill trailers for dispatch to local off-takers, and supply green hydrogen for commercial and private road transport. A large-scale photovoltaics plant will provide part of the energy needs for the water electroysis.
In partnership with Hexicon AB, Avapa Energy is also exploring the production of green hydrogen from off-shore wind energy, for future use in maritime transport and supply to industrial hubs.
Managing to store large quantities of green hydrogen at sea will also make the dream of Long Duration Energy Storage (LDES ) closer and viable. LDES will play a central role in the resilience of a new energy system by greatly enhancing its flexibility.
Solar Hydrogen Energy Systems
Science and Technology for the Hydrogen Economy
It is just a matter of time before fossil fuels become completely depleted or too uneconomical to retrieve. In light of this development, the current fossil fuel era is meant to draw to an end. If on top of this problem of diminishing availability we also add the environmental pollutions the fuels have caused, it is understandable why we must soon find ways to end the current period and enter a new energy era.
Hydrogen is one of the most promising candidates capable of assuming a leading role during this historical transition. Needless to say, the energy needed to obtain hydrogen cannot be provided by fossil fuels. It is therefore necessary to turn to renewable energy sources which are inexhaustible.
The work is structured into eleven chapters to present the readers with advanced knowledge on the functioning and the implementation of a solar hydrogen energy system, which combines different technologies efficiently and harmoniously to convert renewable energies into chemical energy stored in the form of hydrogen and then to a much more exploitable form of energy, electricity.
