Reducing emissions opportunities and challenges across sectors
The upfront capital cost of low emissions process heat equipment, while substantial, is often competitive with or cheaper than fossil fuel fired assets. However, the cost of refurbishing and extending the life of an existing fossil fuel asset is often cheaper and easier than replacing it with a low emission alternative.
