The national electricity grid consists of nine generating stations (3 hydro and 6 thermal) with a total installed generating capacity of 5906 MW, while current estimated demand is 30,000 MW. As a result, there is supply and demand inbalance which leads to 2400 MW of self-generation, in the form of small unit diesel and petrol generating sets, by those who can afford it. Beyond the reach of grid electricity and private generating sets, remote and rural people rely on kerosene for lighting needs and dry cell batteries for low-power appliances. Besides, inadequacy and unreliability, energy supply in Nigeria is directly fossil fuel based. It is expected that in few decades ahead consumption of fossil fuels will decline because of their climate change implications for the environment. It is important for these reasons, that Nigeria diversifies its energy sources and intensifies research on renewable energy options. Thus, expanding Nigerian fuel mix to involve magneto-hydro-dynamic (MHD) option will increase access to reliable energy in the immediate and foreseeable future. There are varied applications of MHD energy, especially for solving geophysics, astrophysics and engineering related problems. However, thrust of this study is on power generation using MHD generator to transform thermal energy into electricity at high temperature. Presented in this paper are the resource summary and market opportunities for MHD energy in Nigeria. Mobility factor is a veritable criterion for wide choice of MHD option as source of energy of the future. Transport, information and communication sectors are the major explanations for MHD energy requirements in Nigeria. They account for 80% of Nigerian energy expenditure. Within the transport sector, both passenger and freight with 31010 and 43606 vehicle import statistics, new and fairly-used respectively, the necessity for MHD applicability in Nigeria is evident. The specific objectives of this study include highlighting the abundant market potentials for MHD energy and examining its role in ensuring energy security for Nigeria. A method of comparative analysis between MHD technology and other efficient energy technology options would be carried out with a view to exposing the materials, infrastructure and extent of their applications in Nigeria. The study also carried out an analysis of human capital requirements for MHD alongside other technologies like the nuclear power industry. For justification, the study enumerated the expected contributions of MHD to on-going energy reforms in Nigeria, particularly security of energy supply. The results of the study show that the country has an abundance of market potentials, human capital resource and materials pools for a MHD development. To position the human capital resource pool for effective utilization of MHD technology, training is essentially important and it is recommended as a matter of priority attention. Strong argument for the integration of MHD system into national Renewable Energy Master Plan (REMP) is in favour of remote and rural areas where accessibility to grid supply is low due to difficult terrain and low service connection ratings. Increased access to energy by the rural poor is a necessity for eradication of poverty and achievement of sustainable development. It is hoped that MHD energy, if developed in the country, would contribute to reduction of climate change, deforestation and helps to ensure increased availability, affordability and accessibility of energy supply.
