So, What Exactly Is Green Hydrogen?

How do you produce green Hydrogen?


With electrolysis, all you need to produce large amounts of hydrogen is water, a big electrolyzer and plentiful supplies of electricity.

If the electricity comes from renewable sources such as wind, solar or hydro, like in our case, then the hydrogen is effectively green; the only carbon emissions are from those embodied in the generation infrastructure.

The challenge right now is that big electrolyzers are in short supply, and plentiful supplies of renewable electricity still come at a significant price. 
This is a huge advantage of this project! Everything we need - we still have that in our partner-network.


How do you store and use this stuff?

Theoretically, there are lots of useful things you can do with green hydrogen. You can add it to natural gas and burn it in thermal power or district heating plants. You can use it as a precursor for other energy carriers, from ammonia to synthetic hydrocarbons, or to directly power fuel cells in cars and ships, for example.


To start with, you can use it simply to replace the industrial hydrogen that gets made every year from natural gas and which amounts to around 10 million metric tons in the U.S. alone.

The main problem with satisfying all these potential markets is in getting green hydrogen to where it is needed. Storing and transporting the highly flammable gas is not easy; it takes up a lot of space and has a habit of making steel pipes and welds brittle and prone to failure.


Because of this, the bulk transport of hydrogen will require dedicated pipelines, which would be costly to build, pressurizing the gas, or cooling it to a liquid. Those last two processes are energy-intensive and would further dent green hydrogen’s already underwhelming round-trip efficiency.

The PILMAIQUEN project is directly located, where it can be shipped, no pipelines are needed.

Why is green hydrogen suddenly such a big deal?

One of the paths to near-total decarbonization is electrifying the whole energy system and using clean renewable power.  Green hydrogen is one of several potential low-carbon fuels that could take the place of today’s fossil hydrocarbons.

Admittedly, hydrogen is far from ideal as a fuel. Its low density makes it hard to store and move around. 

But other low-carbon fuels have problems too, not least of which is cost. And since most of them require the production of green hydrogen as a precursor, why not just stick with the original product?

Proponents point out that hydrogen is already widely used by industry, so technical problems relating to storage and transport are not likely to be insurmountable. Plus, the gas is potentially very versatile. 


The opportunity for green hydrogen to be applied across a wide range of sectors means there is a correspondingly large number of companies that could benefit from a burgeoning hydrogen fuel economy. Of these, perhaps the most significant are the oil and gas firms that are increasingly facing calls to cut back on fossil fuel production.


Several oil majors are among the players jostling for pole position in green hydrogen development.


Cutting the cost of green hydrogen production will require investment and massive scale, something we are uniquely positioned to provide.

TRANSPORT


A liquefied gas is the liquid form of a substance which, at ambient temperature and at atmospheric pressure, would be a gas. The same liquefied gas at the same temperature, in a closed container, will always have the same pressure.

STORAGE


Hydrogen can be stored physically as either a gas or a liquid. Storage of hydrogen as a gas typically requires high-pressure tanks (350–700 bar [5,000–10,000 psi] tank pressure). Storage of hydrogen as a liquid requires cryogenic temperatures because the boiling point of hydrogen at one atmosphere pressure is −252.8°C. Hydrogen can also be stored on the surfaces of solids (by adsorption) or within solids (by absorption).

ZERO CO2 Emission

ZERO emissions is not just a trivial goal. ZERO emission is our DNA, our self-image. That's all we work for every day. We all have a responsibility to our family and to our planet Earth.
