Green Power Production that Leverages...
Green Power!
As can be expected for most hydrogen production projects that have low-CO2 targets, electricity will be sourced from green energy sources – specifically, photo-voltaic (PV) solar panels, wave, gas, or water turbines installed in situ.
Due to the electricity generated from the high-pressure oxygen produced as a byproduct, substantially less of even this green-energy electricity is required, compared to alternative installations approaches. This reduces the installation’s carbon footprint due to less green-energy equipment being manufactured and transported, and less electric transmission lost due to proximity. Next, we avoid producing a significant amount of CO2 production by not consuming treated and transported water feedstock.
Finally, there are indirect benefits of potentially re-using an otherwise unused oil platform, which also has positive impacts on CO2 emissions (e.g., avoiding energy spent to decommission a platform)
Additional benefits of our offshore installation:
Natural high-pressure environment
Conducting electrolysis at a depth of 10,000 feet provides a production advantage of 300 bar and saves substantial hydrogen gas compression costs that would otherwise be unavoidable. Flexible piping for the high-pressure hydrogen gas, from a depth of 10,000 feet to the platform, is readily available with no discernable environmental risks.
Salt-water feed-stock
Key to this application is the need to draw salt-water feed-stock sourced at the electrolyzer’s placement. This provides cost savings by avoiding municipal or freshwater sources, which have their own direct or inherent costs. These cost savings are anticipated to be beneficial, even when considering the system consumables. The availability of near-limitless seawater also provides for the scalability of production sites.
Energy harvesting of high-pressure oxygen as a by-product
MDE has patented a system design to capture energy from the inherently high-pressure oxygen produced by essentially reducing this by-product gas from 300 to 1 bar.
Inexpensive electricity sources
Looking to the future: While the installation of photo-voltaic solar panels in-situ is anticipated, the US may follow Norway’s and Netherlands’ leads to power new oil platforms with offshore wind generators. This would have beneficial investment considerations if the electricity produced could be used beyond the oil platform's production life (i.e., powering an electrolyzer).
Logistics savings
Offshore platforms already have the infrastructure, or the logistical means, to transport oil or natural gas to onshore locations. By virtue of co-locating the electrolyzer on these platforms, there are potential additional capital cost savings when compared to electrolyzer operations that are not collocated with oil or gas infrastructure.
