Definitions

  • the present invention relates to means for production of hydrogen without pollution of the environment.
  • the hydrogen is produced using the process of electrolysis of water where hydrogen gas is released and can be used for fuel.
  • the electricity used comes from environmental friendly sources and emission free production
  • Hydrogen will be important in the decarbonisation of the whole transport sector, which carries heavy or long haul, and needs larger amounts of energy than is optimal for batteries. This makes hydrogen a good renewable alternative to fossil energy sources.
  • Windmills have become popular, and most of windmills have been placed on land; however, to increasing protests on large footprint - impact on landmasses, nature and birds. Windmills at sea are increasing, however this requires large investments, complex installations and large footprint. The performance is also uneven (dependent on wind - 41% of theoretical maximum) and must rely on backup power from shore or gas turbines. The total CO2 footprint is also an issue.
  • the circulation of water can be performed as a multi-well operation, or from a single well.
  • Most oil producing fields are being operated with producing wells and injector wells. Water is being injected into the reservoirs by the injector wells with the task of ‘pushing’ or ‘pressing’ the oil into the producing wells.
  • the producing wells are producing far more water than oil and as the wells are being closed off the producers are showing mainly water, and water is basically running in a cycle. In some cases, this cycle could be used to extract heat energy on the surface and recycle water, the advantage being that the existing well infrastructure can be used with limited modification.
  • Hydrogen is an environmentally friendly fuel of which at this moment in time is of high demand in the world market. Hydrogen used in fuel cells is still in minority amongst zero-emission vehicles. Cars loaded with heavy batteries is at the moment the usual solution but includes heavy weight and relative long charging cycles. This is why marine and air transport is still to be electrified or run-on other emission free fuel.
  • Hydrogen can also replace the use of natural gas for heating and stoves in countries that have a developed gas pipeline network.
  • the following invention will disclose how hydrogen can be environmentally friendly produced by using electricity from Organic Rankine Cycle (ORC) system, especially offshore from reuse of old marine hydrocarbon installations.
  • ORC Organic Rankine Cycle
  • the invention seeks to contribute towards transforming the offshore oil and gas industry into environmentally friendly energy production. Electricity production may extend an installation of lifetime and postpone cost of decommissioning.
  • the invention will include a system and method for using the produced electricity in an electrolysis process for releasing hydrogen and 02 from water.
  • US 6000471 Langset, Dec. 14, 1999, discloses a method for using old wells offshore, earlier used for the extraction of hydrocarbons, for the now new use for extraction of geothermal energy.
  • the offshore installation is proposed for using means for converting the heat energy into electricity using pipes in loops to conduct the heat exchange fluid through the existing wells.
  • US 2013/0300127 A1 DiNicolantonio, Nov.14, 2013, discloses a method and apparatus for recovering geothermal heat from abandoned sub sea oil wells and converting it to electricity.
  • US 8616000, Parella, Dec. 31 , 2013, also discloses a system for recovering geothermal heat from predrilled oil wells, other pre-drilled operations and new wells, to generate electricity.
  • KR20150074709 discloses a floating charging station for vessels, powered by windmills. This solution is however dependent on wind and the power of the wind as mentioned above.
  • the present invention relates to means for production of hydrogen without pollution of the environmental.
  • the hydrogen is produced using the process of electrolysis of water where hydrogen gas is released and can be used for fuel.
  • the electricity used comes from converting geothermal energy into electricity utilizing an Organic Rankine Cycle (ORC) system.
  • ORC Organic Rankine Cycle
  • Offshore installations built for drilling and production of hydrocarbons is converted into geothermal energy plants, for production of electricity of which is used for production of green hydrogen and oxygen.
  • the plant or part of the plant may be located subsea but close to depleted, halted or abandoned oil and gas wells.
  • the electrolysis process may work either by using water from sea or by using steam,
  • the method for utilising steam in the electrolysis process makes the production more efficient and means that the electrolytes do not have to be of high cost metals.
  • Steam is available from the process of the ORC. It may also be produced exclusively from a heat exchanger directly connected with the electrolysis process.
  • the ORC plant and electrolysis plant may support a fuelling station offshore and support for marine vessels a hydrogen fuel station, out at sea. Such a station at sea, far from land, will include landing facilities for helicopters and means for refuelling of electrified and fuel friendly aircrafts.
  • Such a station can provide service to any marine vessel and helicopters or aeroplanes and their crew/passengers including hotel facilities and food production.
  • the invention therefore represents a system and method for production of hydrogen and oxygen through electrolysis by use of electricity from ORC powerplant utilizing offshore geological sources.
  • the invention is further disclosed in the following description and as defined in claim 1 and following subclaims 2-7.
  • FIG. 1 shows an illustration of the production of hydrogen and oxygen
  • FIG. 2 shows an illustration of the offshore installations for providing of hydrogen and oxygen gas to a station where vessels at sea and to helicopters may refuel.
  • the station will have functions as a service station, with hotel services as accommodations and food.
  • the electricity produced by the ORC is used to produce green hydrogen according to the invention as the following will in more detail be disclosed.
  • the electricity is through the ORC produced via heat exchangers and turbines, several options are available to produce hydrogen and oxygen; either by method of electrolysis by use of sea water 107 or based on vaporized water available from ORC process.
  • FIG. 1 shows an illustration of the production of hydrogen and oxygen where the electrolysis plant 100 preferably is sited on an offshore platform with access to energy and other sources from an offshore geothermal powerplant 102 (ORC) as part of this invention.
  • ORC offshore geothermal powerplant 102
  • Electricity 104 and water 105 for the electrolysis process 1 10 is avalable from the pumpstation of the geothermal powerplant and ORC 102, or is pumped directly from sea 108’ or through a filtering system to split the components of sea water. If the electrolysis process use steam 109, this is available also from the heat exchange system of the ORC 102.
  • Numeral 106 denote heat fluids from well 101 and or rock/earth 103, numeral 108 water for cooling.
  • the electrolysis process produce hydrogen 112 and oxygen 1 13.
  • the hydrogen and oxygen can be compressed and stored as gas 120 or liquid 121.
  • the gas hydrogen gas can be compresses to for example to 70MPa for storing or transportation.
  • the gas must be cooled down to -252,87 Celsius and stored in cryotanks for transportation as liquid.
  • the process equipment electrolysis plant 100’ and storage can be installed on the seafloor, located subsea as indicated by numeral 140. This option will safeguard operations with regards to consequences of leakage than for operations onshore in that the hydrogen here is largely absorbed by the water and that explosions are far less likely to happen.
  • Subsea operations will require digital tools and artificial intelligence replacing personnel and improving safety and reducing costs.
  • the hydrogen is well suited for fuel and may be available from a station 130, for refuelling seagoing vessels.
  • the hydrogen and oxygen may also be sold and exported 132 all over the world, either compressed or as liquid, or directly to customer through a pipeline 134.
  • Ell’s Emission Trading System may include the world’s fleet of ships which therefore will have to convert to emission free fuel making energy stations out at sea for electrified vessels and refuelling of vessels with hydrogen technology, will be of demand. This will also save steaming time to port for vessels, which does not need to go to port.
