Hydrogen power plant agreement signed
HECA, which is owned by Hydrogen Energy International, BP Alternative Energy and Rio Tinto, plans to construct an advanced integrated gasification combined cycle (IGCC) plant that will produce power by converting fuel — a blend of 75 per cent coal and 25 per cent petroleum coke — into hydrogen and CO2.
The hydrogen will be used to fuel a combustion turbine, enabling net generation of 250MW of electricity, which is claimed to be enough power for more than 150,000 homes.
Approximately 90 per cent of the CO2 produced from the gasification process (approximately two million tons per year) will be transported via pipeline to the nearby Elk Hills oilfield where it will be sequestered.
The estimated capital cost for the project is approximately $2.3 billion. Sequestration of two million tons per year of CO2 is slated to begin by 2016.

Current Model For Storing Nuclear Waste Is Incomplete
COLUMBUS - The materials the United States and other countries plan to use to store high-level nuclear waste will likely degrade faster than anyone previously knew because of the way those materials interact, new research shows.
The findings, published today in the journal Nature Materials (https://www.nature.com/articles/s41563-019-0579-x), show that corrosion of nuclear waste storage materials accelerates because of changes in the chemistry of the nuclear waste solution, and because of the way the materials interact with one another.
"This indicates that the current models may not be sufficient to keep this waste safely stored," said Xiaolei Guo, lead author of the study and…
