While significant progress has been made in general decarbonisation, achieving net zero hinges on addressing the most hard to abate sectors like iron, steel, cement, chemicals, and heavy transport (e.g., aviation), where electrification is not a straightforward solution.. 2.
Currently, 100 million barrels of oil are used per day, with more than half of our global energy predicted to still be coming from fossil fuels by mid-century.This reality would lead to a three to four degree trajectory of warming, and a very bad environmental outcome.. One potential decarbonisation solution Terra Praxis has been exploring is the possibility of very low-cost, large-scale hydrogen production.
Hydrogen is difficult to store, transport and move around, so it isn’t particularly useful as an end product, as it would require a lot of new infrastructure for end users.However, it does have strong potential as an ingredient in clean, drop-in, substitute fuels, such as ammonia (which can be used as a Marine shipping fuel), or synthetic hydrocarbons.Importantly, this would mean that existing storage, transport and end-use infrastructure could continue to be used, including the use of today's planes and ships, making these kinds of solutions extremely useful..
The sticking point is that in order for hydrogen to be used successfully as an ingredient in these alternative fuels, it needs to be very inexpensive, costing less than one dollar per kilogram.This is significantly out of range for any of the prospects for renewables until 2050, largely because they are very dispersed, dilute energy sources.
Despite building renewables in windy and sunny places, and combining them to increase the capacity factors, there’s still a cost to transport those fuels around the world, leading to high prices.
In contrast, with advanced heat sources, it’s possible to move into a shipyard based manufacturing environment to make offshore production platforms.For this, a diagram to spatially explore how this might work is a key tool for communication and design.
Once all the stakeholders can understand and visualise the connections, designing a physical space unfolds.Function comes first.. To purchase this book, visit.What came to me was not a revelation but a simple remembering.
Only three weeks ago I was involved in a webinar and I remember saying “Design to Value represents an ‘and’ rather than an ‘or’…”.The reason why it seems so hard to take choices which will protect us in the longer term is that we believe that to do so will lessen or lives, our livelihoods, our success in the short term.
