Delivering Clean Hydrogen Fuel from Ammonia Using Metal Membranes

ABSTRACT

The use of ammonia (NH3) as a hydrogen vector can potentially enable renewable energy export from Australia to markets in Asia and Europe. With a higher hydrogen density than liquid H2, plus existing production and transport infrastructure, and well-developed safety practices and standards, the financial and regulatory barriers to this industry are lower than for liquid H2 transport. The only significant technical barrier which remains, however, is the efficient utilisation of ammonia fuel at or near the point of use, either directly or through the production of H2.

ABSTRACT

There are severe issues on increasing amount of carbon dioxide (CO2) emission in the world. Many studies are devoted on alternative fuels. One of superior candidates is the utilization of hydrogen energy which can realize a low-carbon and hydrogen-based society. Ammonia might play an important role which is zero emission of CO2, and is useful for hydrogen energy carrier as a clean energy. Additionally, ammonia is an easily-liquefiable fuel with pressure of about 0.86 MPa and temperature of 293 K. Commercially, ammonia is produced in large quantity by the Haber–Bosch process. It is also to be produced by using catalyst with renewable energy sources, such as wind energy and solar energy. Continue reading

Ammonia Renewable Energy Fuel Systems at Continental Scale

AIChE Annual Meeting, Topical Conference: NH3 Energy+

ABSTRACT

We must soon “run the world on renewables” but cannot, and should not try to, accomplish this entirely with electricity transmission. New, abundant, low-cost, unconventional natural gas supplies are finite; burning adds CO2 to Earth’s atmosphere.

Humanity’s goal must be nothing less than: Transforming the world’s largest industry from ~80% fossil to ~100% renewable, CO2-emission-free energy sources as quickly as we prudently and profitably can.

We should now carefully consider using pipeline networks, rather than the electricity grid, for solving the three salient technical problems of renewable energy (RE) at lower cost Continue reading

Nitrogen-Based Fuels: Renewable Hydrogen Carriers

AIChE Annual Meeting, Topical Conference: NH3 Energy+

ABSTRACT

Renewable energy sources such as solar and wind suffer from an intermittent power output, making energy storage a key element in future energy infrastructure. Fuels offer both high energy densities and efficient transport compared to other energy storage alternatives. One energy storage solution is water electrolysis. However, the generated hydrogen is incompatible with the global fuel infrastructure, inhibiting its implementation as an energy vector. Storing hydrogen on carrier atoms provides a safe and convenient way to utilize and transport renewable energies. While carbon–based fuels are commonly suggested, using nitrogen as a hydrogen carrier can potentially offer a superior option. Continue reading

NH3: The Optimal Alternative Fuel

NH3 Fuel Conference 2017, Minneapolis, November 1, 2017
AIChE Annual Meeting, Topical Conference: NH3 Energy+

ABSTRACT

Unlike some technology areas where “all of the above” has significant advantages, there are tremendous advantages associated with choosing a single, optimized, liquid transportation fuel. The cost, efficiency and environmental benefits associated with choosing an optimized liquid transportation fuel are enormous and merit serious consideration.

NH3 most closely meets the criteria for an ideal liquid transportation fuel. Continue reading

Japan – a future market for Australian solar ammonia

NH3 Fuel Conference, Los Angeles, September 20, 2016

ABSTRACT

Japan and Australia are intimately linked in energy trade. Australia counts energy exports as a major source of foreign exchange income and Japan, which uses nearly 4 times the primary energy as Australia, imports nearly all of it. Approximately 40% of Australia’s coal exports are bought by Japan and were worth $AUD15.4 billion in 2012-13. Over 70% of Australia’s LNG exports went to Japan in the same period and earned over $AUD12billion. Future energy supply is high on the agenda for Japan. Currently 43% of its primary energy is in the form of imported oil mostly from the Middle East. The cost of this together with energy security concerns is a major driver for change. Post the Fukushima Nuclear disaster, the previous 8% contribution from Nuclear dropped to zero and there is much opposition to reinstating it. Japan still has a strong policy agenda to reduce Greenhouse Gas Emissions.

One of the identified routes to a cleaner energy future is the wider use of hydrogen as a fuel in both the transport and power generation sectors. There are a range of technology approaches that allow solar technologies to produce transportable alternative fuels that could form the basis for a future clean energy trade with Japan. If energy is transported as an energy dense liquid in conventional tanker ships, then the effective efficiency of transport over distances of 6000km (Australia to Japan) is greater than 98%. Three options for importing hydrogen fuel into Japan are under serious consideration; cryogenic liquid hydrogen, reversible hydrogenation of toluene, and conversion of hydrogen to ammonia. Ammonia is increasingly considered as the favourable path. It offers higher energy density, leverages an existing global industry and has the potential for direct combustion in combined cycle power plants and heavy transport. Considering Australia’s vast untapped solar resource together with the existing energy trade history plus a history of upstream investments by Japanese companies in Australian Energy developments, suggests the two countries are ideal partners in a future solar fuels trade.

ABSTRACT

Ammonia is a promising hydrogen carrier because of its high hydrogen density, low production cost, and ease in liquefaction and transport. Ammonia decomposes into nitrogen and hydrogen through a mildly endothermic process. The ammonia decomposition temperature is close to the operating conditions of solid oxide fuel cells (SOFCs). Therefore, the integration of these two devices is beneficial in terms of efficient heat and energy managements and will lead to the development of simplified generation systems. Continue reading

ABSTRACT

In this talk, I will discuss our latest research in developing novel ammonia cracking catalysts. While ammonia can be used directly as a fuel in high temperature fuel cells, internal combustion engines and gas turbine, the ability to crack ammonia affordably and effectively increases the range of possibilities for utilising ammonia as an energy vector.
