Sub-Saharan African countries could become big hydrogen exporters, but why not use hydrogen to power their own industrial development?
After years of hype, "freedom fuel" has yet to prove itself as a transport solution.
A refusal by Russia to fully take part in the global clean energy transition could have serious economic and political repercussions for the country.
Hydrogen has an important role to play in the clean energy transition, but there are better options for decarbonising heating in our homes.
A climate neutral energy system requires green hydrogen made from renewables to transport and store clean power, and take it into other sectors such as industry and transport. Europe is taking a lead, but climate campaigners caution that hydrogen must really be green and remain complementary to direct electrification.
While the goal may be green hydrogen from renewable power, blue hydrogen from natural gas with carbon capture and storage will be a cheaper, faster way to reduce industrial emissions and build demand for clean hydrogen over the next ten years.
Decarbonising heating is essential to reach net zero greenhouse gas emissions by 2050, but the UK Government is still hesitating about which path to take.
