INTRODUCTION

The aim of the invention is to develop a simple structure of an system for transporting and storing, in particular hydrogen and its mixtures, primarily energy produced by renewable energy sources and surplus energy networks, as well as other ecological energy sources such as nuclear power plants or other ecological sources of low-emission (green) hydrogen production. 

On the other hand, the possibility of vertical direct connection of terrestrial consumers to this installation will result in significant savings in the design and construction of hydrogen, or its mixtures, distribution stations, which will also have a positive impact on the popularization of hydrogen as fuel, with a simultaneous significant reduction in the costs of its production and distribution.

A further aim of the invention is to develop such a system for transporting and storing hydrogen, in particular hydrogen and its mixtures, which in the future will allow for the creation of local universal networks for the production, distribution, and consumption of hydrogen as an alternative method of obtaining energy for various purposes. These networks will naturally be able to connect with each other into larger and larger areas, providing a cheap form of “hydrogenation” of the future society, without any barriers and limitations, which will be ensured by horizontal drilling conducted in various directions, at various angles and at any depth, without the need to carrying out groundworks and related difficulties and inconveniences.

The installation for transporting and storing hydrogen and its mixtures from their supplier to the consumer, partially located underground, is characterized by the fact that it consists of at least two vertically arranged tubular elements connected with each other by another tubular element, forming together a U-shaped tubular profile, whereby the upper end of the vertical tubular elements is connected via a non-return valve to a tubular element into which hydrogen and/or its mixtures are pumped from another tubular element connected to at least one hydrogen and its mixtures, and the upper end of the second vertical tubular element by the non-return valve is connected to a further tubular element connected to at least one consumer of hydrogen and/or its mixtures.

The use of transport and storage systems, in particular hydrogen and its mixtures, obtained by electrolysis from cheap, local renewable energy sources or unused energy surpluses of the national system, as well as blue hydrogen produced from fossil fuels in combination with CO2 capture or other green hydrogen production methods, according to the invention, will allow:

  • a safe, automatic, immediate, and non-contact transporting of hydrogen/gases from the producer to the consumer as well as safe and ecological storing also in the long term without losses, significant amounts of gases/hydrogen in a state of high concentration
  • simultaneous supplying gas/hydrogen to the installation from various sources (suppliers) located in different places and it’s supplying to independent consumers (which will eliminate the dominance of energy and fuel monopolies – free energy)
  • significant reduction in the price of hydrogen/gas at the end consumer, also caused by the elimination of expensive road transport
  • using and revitalizing the existing, no longer active mining wells, which will also contribute to reducing the level of methane escaping into the atmosphere – a dangerous greenhouse gas
  • significant reduction in costs of construction and operation of gas/hydrogen distribution stations, their physical size and location, as well as accompanying infrastructure

USE CASES

The patent application was filed with the Polish Patent Office on October 31, 2021. It is a proposal
for a comprehensive and systemic solution to the problem of storing and transporting hydrogen,
including enabling the construction of fully energy-autonomous houses and other public utilities
and workplaces, hydrogen or electricity consumption points using renewable energy (green
hydrogen) and possible central surpluses of energy, based on hydrogen.

The Patent Application has already obtained a positive preliminary opinion of the Patent Office
and a positive Report on the State of Technology, Initial Opinion Hydrogen, Hydrogen Report.

On October 28, 2022, in accordance with the PCT procedure it was submitted for further
international processing and expansion to the world.

Thanks to this simple solution, at a very low cost it will be possible to obtain fully capacious energy storage for year-round use of surplus solar energy, collected mainly in the summer months, and to adjust the capacity of this storage to individual needs of a single energy consumer.

This is illustrated by a simple calculation. In addition, to produce 1 kg of hydrogen, one has to use as much as 9 liters of demineralized water (0,25 USD/l).

In HBS scheme, thanks to the possibility of recovering water (as a by-product of electricity production from hydrogen), water can be reused for the production of hydrogen (closed cycle), which can reduce the cost of producing 1 kilogram of hydrogen alone by 1,25 USD, while saving consumption the same water as water.

The hydrogen car filling stations built according to HBS will certainly demand much less space and smaller safety zones. This is due to the lack of cubature hydrogen tanks (and the land in cities is expensive), as hydrogen can flow directly to the distributors through pipes “from below”.

In this way, it will be possible to supply and store hydrogen to virtually every customer, from every hydrogen producer. By building a completely new supply system network in this way, it will be possible to store almost any amount of hydrogen very safely in the underground network.

11 km U-tube with a diameter of 30 cm and a standard pressure of 700 bar can equally power up to 100 single-family houses in a moderate climate for the entire year.

In Poland for example, the average annual temperature is around 6-8°C, the annual rainfall is around 700 mm, the annual averages of insolation are 1600 hours, which is 30-40% of the length of the day – which requires 4,500 KWH per year.

On the route of such underground hydrogen pipelines, HBS also allows the construction of small and medium-sized ecological hydrogen power plants, for a specific, limited number of recipients, in a small, defined area (without the need to use expensive electric power transmission lines).

In this way, hydrogen cells produce a certain amount of energy needed at a given moment, from the hydrogen stored underground (similarly to charging additional gas in a hydrogen car only when needed). That is how New Distributed Energy develops.

It is possible to connect the HBS network even to a very large plant consuming large amounts of hydrogen-based energy in its production process (e.g. producers of ammonia fertilizers). The most efficient would be to build such a network of HBS pipes within a radius of a number of kilometers around such a plant. This way, the supply of hydrogen, meaning constant energy as well, can secure continuity of the production process for a long time in advance (despite depending on both transport and availability of hydrogen from outside suppliers).

The HBS can be a great buffer for the use of energy surpluses of other power plants (nuclear, coal, gas, RES, etc.) in the hours of falling energy demand while supporting the national energy system during peak hours.
