Steam Methane Reforming (SMR) and Water Gas Shift (WGS) which includes a heat pump/heat recovery system that extracts heat from the produced gasses (H2 and CO2) and feeds the heat energy into the endothermic SMR process. The complete process (CH4+H2O -> CO2+H2), including capture of liquid CO2, occurs inside a single rotating device.

Steam Methane Reforming (SMR) and Water Gas Shift (WGS) which includes a heat pump/heat recovery system that extracts heat from the produced gasses (H2 and CO2) and feeds the heat energy into the endothermic SMR process. The complete process (CH4+H2O -> CO2+H2), including capture of liquid CO2, occurs inside a single rotating device.

Methane (liquid (LNG) or gaseous) and water is led into the rotor. These streams are led out ("down") towards the periphery while they are heated, evaporated and compressed (by their own masses in the High-G-environment). There will be excess water as an heat/energy carrier to reduce the temperature spans in the processes. The gasses are mixed and enters the catalytic SMR reactor at the periphery splitting the methane and part of the water to CO and Hydrogen. This gas mixture flows further "up" towards the center of the rotor and enters the WGS reactor where the CO and water combines to CO2 and more Hydrogen. This mix of Hydrogen, CO2 and water is then further led towards the rotational axis and cooled against the cold section of the heat pump, where first water then CO2 is condensed out to liquid state and separated from the flow. The water is returned and mixed with the feed water flow and the liquid CO2 and the hydrogen gas exits the rotor in two separate channels. Vis mindre

We are honored that our client (APL/NOV) has decided to chose us to manufacture and deliver doors for their project. We delivered 10 H0 rated doors, pneumatic operated, gas tight and in accordance to the HSE standards for their Submerged Turret Production (STP). The doors are to be installed in different decks in their STP compartments. Fully technical documentation, including FAT, MC Package, and other technical documentations were executed.

We are honored that our client (APL/NOV) has decided to chose us to manufacture and deliver doors for their project. We delivered 5 A-60 rated doors, pneumatic operated, gas tight and in accordance to the HSE standards for their Submerged Turret Production (STP). The doors are to be installed in different decks in their STP compartments. 3 of these doors were to be submerged underwater (approx. 14m for the one at the deepest level) and are expected to fully function afterwards.

Baggerød AS succesfully sold fire doors to the JSP2 project, a project run by Equinor. My responsibilities included GA (general arrangements) drafts to the customer for approval, detailed production drawings according to ISO and NORSOK standards, handling customer communications and attending to bi-weekly meetings for updates from both parties.

A RotoHeatPump use two different gases with different heat capacity in separate channels, and therefore receive different degrees of heating on the path from the inlet to the periphery.
Using data gathered from the first 2 prototypes, together with the CEO/Managing director and the project leader, I created a revolutionary design which fully utilized the centrifugal force, heat capacity and the capabilities of the gasses running during the operational tests.

A RotoHeatPump use two different gases with different heat capacity in separate channels, and therefore receive different degrees of heating on the path from the inlet to the periphery.
Using data gathered from the first 2 prototypes, together with the CEO/Managing director and the project leader, I created a revolutionary design which fully utilized the centrifugal force, heat capacity and the capabilities of the gasses running during the operational tests.

Just like my parallel projects (RotoLyzer and RotoEvaporator) I took on the initiative to contact companies for research purposes, purchase of tools and supply of materials.
I worked together with 3 different PhD candidates from University College of Southeast Norway and together we ran various FEM (finite element analysis) to conclude which design concept would be the best course of action to proceed with.

Followed up with local workshop, making sure the parts were made according to ISO standards and blueprints and performing QA (production control). Vis mindre

4th prototype of the device RotoLyzer. A complete hydrogen production plant based on RotoLyzer® technology. Making it significantly less complex, smaller, and have very low investment and gas production costs. This device was purchased and is now owned by NEL hydrogen (world leading hydrogen manufacturer) since 2015.

Making it significantly less complex, smaller, and have very low investment and gas production costs. This device was purchased and is now owned by NEL hydrogen (world leading hydrogen manufacturer) since 2015.

Working closely with the CEO/Managing director, I created a creative design which resulted in cost-effective production. Working together with a colleague, we designed an improved version of an P&ID for the plant. Following up with the project, I ran quality assurance on the blueprints as well as the parts which were created. I was also responsible for setting tolerance on every dimension on every mechanical drawing.

Because we were a small team I took the initiative to take on extra responsibilities such as: contacting various companies for tools and supply of materials, workshops, certified ISO companies.
With this I managed to supply the company with the required machines, tools and materials needed to finish our prototypes from other projects including the RotoLyzer.

I also performed on-site quality assurance, making sure that the device the correctly put together and connected according the mechanical drawings and P&ID drawings. Vis mindre

Utilizing artificial G-forces, pressure and cooling to extract clean water from salt/tap water.

This was a short project were its original purpose was to produce clean water for the RotoLyzer. Although experiment and calculations proved that this design if used on a much larger scale would be able to clean saltwater and dirt water. I was mostly working alone on this project.

Utilizing artificial G-forces, pressure and cooling to extract clean water from salt/tap water.

This was a short project were its original purpose was to produce clean water for the RotoLyzer. Although experiment and calculations proved that this design if used on a much larger scale would be able to clean saltwater and dirt water. I was mostly working alone on this project.

The base design I created was simple as RotoLyzer didn’t require much clean water, however, when we wished to experiment the use with salt- and dirt water I had various designs to meet the requirements based on the calculations we made. I also tried to implement a new concept design which allowed the device to be installed in a car, thus combining the RotoLyzer and the RotoEvaporator. The purpose of my idea was for RotoEvaporator to produce clean water and RotoLyzer to create clean hydrogen, thus allowing hydrogen car owners to refuel their car from the tap water from their very own home.
