Hydrogen variable cost analysis for multi-product processes

Joris van Willigenburg: Some hydrogen production technologies produce by-products, such as ethylene. This raises issues on the subject for how to value the resource-savings resulting from these byproducts and how to calculate the variable production costs from these technologies.

Within the Brightsite consortium we have developed a novel and more accurate methodology than commonly used in for example LCA-studies. In this presentation this new methodology will be explained and the results for the variable costs of eleven hydrogen production technologies will be presented.

Joris van Willigenburg, Senior chemical engineer / Technology and sustainability consultant, Sitech Services, will speak at the 2021 edition of the Online Clean Hydrogen conference.


What drives you?

I have a genuine interest in technology and its application for the benefit of society

Why should the delegate attend your presentation?

A novel method was used to allocate energy and raw materials consumption to main and co-products for the calculation of variable costs of hydrogen from process with co-products. The results include meaningful insights in the sensitivity to CO2-pricing and decoupling of oil and gas prices.

What emerging technologies/trends do you see as having the greatest potential in the short and long run?

Short term: Working from home, electric vehicles, solar PV, home insulation, renewable ethylene from ethanol dehydration, extended producer responsibility.
Long term: Waste recycling technologies, green ammonia (or methanol) production in very sunny area’s in stable countries, carbon capture & storage for cement, steel and ammonia

What kind of impact do you expect them to have?

The impact on the applicable industries is great, but small on society.

What are the barriers that might stand in the way?

“The pursuit of final solutions”, complicated policies, too high expectations, economic downturn

About Brightsite

Brightsite is a public-private partnership between four partners. A collaboration based on an open character, which uses an expertise network to realize a transformation in the chemical industry. The Brightsite partners, Sitech Services, TNO, Maastricht University and Brightlands Chemelot Campus signed the cooperation agreement June 2019 and appointed Arnold Stokking as director. Under his leadership, Brightsite started working on the Chemelot site with six program lines.

Our goals closely fit the ambitions of the Dutch government and Province of Limburg. Holland Chemistry embraces this initiative and fully supports the (inter)national ambition.

  1. What applications do you see for low carbon methanol, beyond as chemical feedstock? For example – in mobility?
