How does hydrogen power generation compare to renewable energy sources such as wind?

The HECA power plant will generate clean low carbon electricity by transforming fossil fuels into clean burning hydrogen that provides reliable power to the grid nearly 24h a day 7 days a week regardless whether the wind is blowing or the sun is shinning. Typically renewables, such as wind and solar, produce electricity only one third of the time. So although renewables provide an important form of clean energy they are intermittent.

We believe hydrogen power and renewables are complementary in the sense that both deliver cleaner energy and both are needed to meet greenhouse gas emission reduction targets.

What exactly is a ‘hydrogen power’ project?

Most electricity is now generated by burning fossil fuels – coal, oil or natural gas. Burning fossil fuels creates carbon dioxide, the primary so-called greenhouse gas which, when emitted to the atmosphere, is widely believed to contribute to global warming and climate change. 

The HECA facility’s proposed hydrogen power process transforms fossil fuels into hydrogen to produce clean electricity. Instead of burning fossil fuels this facility will gassify them in a contained process, reacting this gas with water or steam at high temperatures to form a two gases — hydrogen gas and carbon dioxide — which are then separated. There is no combustion of the actual fossil fuels which is the key process that sets HECA apart from conventional power generation. The hydrogen is then used as a fuel to drive a combined cycle gas turbine generator that produces electricity and the captured CO2 is safely injected deep underground into natural geological formations.

The largest growth in coal-fired power generation is expected to come in China – surely that is where your hydrogen power projects would be best put?

California has shown leadership in addressing the climate change issue and is a fitting location for the HECA project which would prove the application of the hydrogen power and carbon capture and storage concept to solid fuels, such as petcoke or coal. There are also very compelling economic development reasons for building this high tech facility in California namely job creation and new local tax revenues. Demonstration of the concept for future application in countries such as China will be a significant step.  China and other countries are also dedicating considerable time and money to identifying potential technologies and projects that will demonstrate the enormous environmental and economic benefits that CCS can bring.

What are the implications for the coal industry as a result of this project using petcoke?

Petcoke is a synthetic product similar to coal so the technology used here will be very similar to the gasification of coal, so the lessons learned in this project will also be relevant for coal.  Demonstrating capture and storage of approximately 90% of the carbon in coal in combination with industrial scale power generation would be a significant step in securing adequate supplies of clean energy for the medium term.
