two of the lowest-cost forms of energy production in the
world, represent just 9.5 per cent of global energy production. And that is after 25 years of intense investments in
markets that are large consumers of energy.
So, while hydrogen may be able to replace that 25 per
cent of global energy demand in the next 13 years, it won’t
simply come from hydrogen produced using wind and solar. Certainly, some of Canada’s own hydrogen production
will come because of new investments in wind and solar.
Evolving the hydrogen conversation
To be successful in integrating a large volume of hydrogen
production into our energy mix, we will have to take a

step back from the politics associated with the colour classification system and focus on the production opportunities that align with the resources available in each region.
That starts with blue hydrogen, which in some circles,
is seen as quite controversial. There are three primary reasons for this, all of which, I believe, can be overcome.
First, there is the fugitive emissions from the source
gas. However, the technology is there to be able to capture
these emissions. And, in addition, we can use satellite
tracking to appreciate the emissions volumes and identify
where we need to address them.
Second, there is an issue around the capture rate. Right
now, the conversion rate is about 90 per cent. That rate is
