The analysis from the Pathways Project (2020) indicated that the countries from the UNECE region will need both to reduce
their dependence on fossil fuels from over 80% to around 50% by 2050 and to achieve significant negative carbon emissions
to stay on a pathway consistent with the Paris Agreement and to maintain its economic trajectory.
The amount of cumulative negative carbon emissions is immense - at least 90Gt of CO2 by
2050 to ensure delivery of the 20C target Fossil fuels are likely to continue playing an important role
in UNECE member States, in the short and medium term, during a transition to carbon neutrality. Hydrogen is widely
recognised as a key to either decarbonise sectors where full penetration of renewable electricity is not possible or where
the deployment of CCUS is difficult (for example, in some hardto-abate sectors, such as some heavy industry and long-haul
transport).
Hydrogen has been produced and used in huge quantities for many years. However, hydrogen as an energy vector is a
recent development. An energy vector is a tool that can be used to transport and store energy before it is converted into
electricity, heat or used as raw material to supply the industry. Unlike fossil fuels, geological resources of hydrogen are
rarely exploited or widely mapped and so hydrogen must be produced directly.
Currently, hydrogen is mostly used as a feedstock to produce chemicals, such as fertilisers and plastics, while its energy
vector feature remains limited. In this context, about 95% of hydrogen is produced from natural gas or other hydrocarbons
and results in CO2 emissions between 70 – 100 Mt CO2 annually solely in EU countries.

Earth’s climate / weather is an incredibly complex system. I would guess we are at least several years away from having models, powerful enough computer-fleets to process them and be able to predict the climate effects before they happen.

The Great Salt Lake is disappearing – Can it be saved? And does it need saving?
The Great Salt Lake has lost half its surface area and 70% of its water volume, yet there remains a debate on whether it needs savings. One group believes it does and is enlisting the support of a tiny bird.

The Energy Central Power Industry Network® is based on one core idea - power industry professionals helping each other and advancing the industry by sharing and learning from each other.
If you have an experience or insight to share or have learned something from a conference or seminar, your peers and colleagues on Energy Central want to hear about it. It's also easy to share a link to an article you've liked or an industry resource that you think would be helpful.
