Description/Abstract
Since mankind's adoption of fossil fuels as its primary energy carrier for heating, elec-
tricity and transportation, the release of greenhouse gases into the atmosphere has
increased constantly . A potential replacement energy carrier is hydrogen. Current
industrial techniques for dissociating hydrogen from its common substances are con-
ventionally reliant on fossil fuels and thus greenhouse gases are still released. As a
mechanism to develop a hydrogen economy current industrial techniques will suffice;
however, a long-term sustainable solution to hydrogen mass production that does not
release greenhouses gases is desired. The United States of America Government be-
lieves that the Sulphur-Iodine thermochemical hydrogen production cycle, thermally
powered by a nuclear source, is the most likely long-term solution. A critical part
of the Sulphur-Iodine cycle is the point of interaction between the thermal source
and sulphuric acid used within the cycle. A novel bayonet heat exchanger made
from silicon carbide is theoretically applied to the point of interaction. Through a
combination of experiments and theoretical modelling, the bayonet heat exchanger is
characterised. The bayonet model is then modified to simulate the intended nuclear
reactor favoured by the United States Department of Energy. In addition, the bayo-
net heat exchanger is analysed for a solar thermal application. An advanced design
of the bayonet is also presented and theoretically analysed for its increased thermal
efficiency.
