In this blog, we discuss challenges faced by SMEs on their journey to sustainability, and opportunities to overcome these barriers to reach their goals.
Is hydrogen worse for the environment than natural gas?
One of the most critical challenges today is the decarbonisation of the global economy. Hydrogen can offer a clean solution to parts of the economy that are difficult to decarbonise or as one of the solutions to our fuel mix dilemma, but is it the most sustainable one?
An ,article published by Sky News warns of the hidden costs of hydrogen. Based on what we know to date, should we or shouldn’t we switch?
To give you an idea of its role in our fuel mix, hydrogen is the common fallback position for all vehicles and heavy industrial machinery that prove difficult to electrify. Hydrogen has distinctive characteristics and is applicable across several sectors, but it is not a homogenous product and there are concerns over its environmental impact.
The immediate challenges hindering the hydrogen sector from scaling are primarily costs and production process. What we intend to focus on today however is whether the change needs to be made in the first place and what the distinction is between what is referred to as “green” vs. “blue” hydrogen.
How can you tell them apart?
The hydrogen spectrum comes down to different sources and production methodologies. The greenhouse gas emissions production rates also vary across the spectrum. The primary hydrogen types are:
Grey Hydrogen – This type is generated from natural gas or methane through a process called steam reforming. Most of today’s hydrogen use is grey.
Blue hydrogen – Heavily reliant on fossil fuels (in the form of natural gas) and it is when natural gas is split into hydrogen and CO2, but the CO2 is captured and stored. The CO2 is captured by Carbon Capture Usage ad storage (CCUS). The capturing of the CO2 mitigates the environmental impact on the planet”
Green Hydrogen – Made with electricity from renewable sources to split water molecules into hydrogen and oxygen.
