Short answer

Prioritize the selection of materials and manufacturing processes for green hydrogen components that minimize adverse social impacts on workers and communities, particularly in regions with higher identified risks.

Field: Sustainability
Source: Renewable Energy (2024)
Method: Social Life Cycle Assessment (S-LCA)
Evidence: Strong effect

A comprehensive social life cycle assessment of green hydrogen production reveals that raw material extraction and processing, particularly for electrolyzers, are the primary drivers of social impacts, with significant contributions from countries like China and South Africa. This sustainability research insight is drawn from a 2024 study published in Renewable Energy. Using Social life cycle assessment (s-lca), researchers explored how this design variable affects real-world outcomes. The key design takeaway: Prioritize the selection of materials and manufacturing processes for green hydrogen components that minimize adverse social impacts on workers and communities, particularly in regions with higher identified risks.

Green Hydrogen Production: Unveiling Social Impacts Across the Value Chain

Renewable Energy · 2024

Key Findings

01Raw material extraction and processing for electrolyzers are the main contributors to social impacts.
02Electrolyzer manufacturing is a significant factor for 'weekly working hours per employee' and 'union density'.
03Nafion® and Iridium were identified as major component contributors to social impacts.
04China and South Africa play a significant role in social impacts, especially in raw material stages.

Application

Design takeaway

How to apply

When designing or specifying components for green hydrogen production systems, actively seek out suppliers with strong ethical sourcing and labor practices, and consider alternative materials with lower identified social risks.

Project actions

01When researching sustainable technologies, don't just look at environmental benefits; also consider the social impact.
02Think about the entire life cycle of a product, from where the materials come from to how it's made and used.

Method & Evidence

AimTo evaluate the social impacts associated with the industrial production of green hydrogen using a social life cycle assessment (S-LCA) methodology.

MethodSocial Life Cycle Assessment (S-LCA)

ProcedureThe study applied the S-LCA methodology to a projected Portuguese green hydrogen production plant, considering the entire life cycle from raw material extraction to production. Data was collected and analyzed using PSILCA and SHDB databases within SimaPro software, focusing on four stakeholder categories: workers, value chain actors, society, and the local community.

ContextIndustrial green hydrogen production

Variables

IV["Stages of green hydrogen production (raw material extraction, manufacturing, production)","Specific components (e.g., electrolyzer, Nafion®, Iridium)","Geographical locations of raw material sourcing and manufacturing (e.g., China, South Africa)"]

DV["Social impacts on workers (e.g., weekly working hours, union density)","Social impacts on value chain actors","Social impacts on society","Social impacts on local communities"]

CV["Type of electrolyzer (proton exchange electrolyser)","Production process (electrolytic separation of water)","Databases used (PSILCA, SHDB)","Software used (SimaPro)"]

Strengths & Limitations

Strengths

+Application of a recognized S-LCA methodology.
+Comprehensive analysis across multiple stakeholder categories.
+Use of established databases and software for data processing.

Limitations

The social impacts identified might vary significantly depending on the specific manufacturing location, labor laws, and company practices.

Reliability & validity

The reliability of the findings is supported by the use of established S-LCA databases and software. Validity is enhanced by considering multiple stakeholder groups and life cycle stages, though it is based on projected data for a specific plant.

Think critically

How can designers proactively mitigate the identified social risks in the supply chains of emerging sustainable technologies, and what tools or frameworks can be employed to achieve this?

Design Principles

"Integrate social impact assessments into the early stages of technology design and supply chain development to foster responsible innovation."

Understanding the social implications of emerging sustainable technologies like green hydrogen is crucial for responsible innovation. This research highlights potential risks and benefits for various stakeholders, guiding designers and policymakers towards more equitable and ethical production strategies.

What This Means for Your Design

Making green hydrogen is good for the planet, but we need to be careful about how it's made. The study shows that getting the materials for the machines that make hydrogen can cause problems for workers and communities, especially in certain countries.

How to use in your project

1.Use this study to justify the importance of considering social impacts in your design project, especially if it involves new technologies or global supply chains.
2.Reference the findings on material sourcing and manufacturing to support your design decisions regarding material selection or supplier choices.

Paragraph starter

This research highlights the critical need to consider social impacts throughout the life cycle of sustainable technologies. For instance, the production of green hydrogen, while beneficial for reducing greenhouse gas emissions, was found to have significant social implications stemming from the extraction and processing of raw materials for electrolyzers, with particular attention drawn to the roles of China and South Africa in these stages.
