Patrick Molloy at Rocky Mountain Institute runs through the pros and cons of hydrogen fuel cell vehicles (FCEVs). The big pluses are that hydrogen has an energy density of around 120 MJ/kg, almost three times more than diesel or gasoline. Half the energy generated by an internal combustion engine is wasted as heat, whereas electric drivetrains used by FCEVs only lose 10%. Nikola Motors, a U.S. maker of hydrogen trucks, claims its vehicles can get … [Read more...]
Coal exit: top Asian banks join Europe, U.S.
Around the world, cheaper renewables, improved technology, and risks over reputation, financial performance and the environment are driving finance away from coal. In the early days it sometimes looked like “greenwash”, but over time commitments have ratcheted up to make it a reality. Europe and the U.S. have already made a good start, and Asia is now catching up. As renewables get cheaper nobody wants to be left holding billions in stranded … [Read more...]
IEA: Renewables growth worldwide is stalling
It’s bad enough that 2018 net capacity additions did not exceed 2017’s after two decades of strong growth. It is far more troubling that nobody saw it coming, says the IEA, who have laid out the data and main cause: stop-go policies. 2018's 180 GW is only 60% of what needs to be added each year to meet climate goals. China, the EU, India and Japan all fell back. Only emerging economies, developing countries and the US (slightly) saw growth. … [Read more...]
Russia to consider ratification of Paris Agreement
In Russia a report on formally joining the climate deal is due for completion by the end of the month. Russia has signed the Paris Agreement but not ratified it, and is the largest GHG emitter of the 13 nations not to have done so. To help change the mindset a key industry lobby has reversed its opposition. They join supporters who warn that non-ratification can now undermine international trade deals, and fossil fuels are inefficient and costly. … [Read more...]
Japan’s new energy strategy should boost both renewables and nuclear power
Japan needs both renewables and nuclear energy in its energy mix to reduce dependence on imports and lower greenhouse gas emissions, writes David Livingston of the Atlantic Council Global Energy Center. According to Livingston, it is in the interest of the international community that the country's new energy strategy, which is expected in the middle of this year, should boost their share in the energy mix. … [Read more...]
