Abstract: In the end of 2010s decade Japan has declared a new policy direction to build a hydrogen energy based society. It should be a major component in full decarbonization strategy by 2050 in the framework of the Paris Greenhouse Agreement reached in 2015. Japan’s economy is highly dependent on imports, especially in energy sector. Diversification of Japan’s energy import represents a major problem, discussed in the article. In the same time significant renewable energy resources could be found just nearby at the Russia’s part of the Sea of Okhotsk. The article views on the Sea of Okhotsk tidal energy potential, and background for the growth of hydrogen production and exports from Russian Far East using tidal energy. The authors consider both advantages and disadvantages of construction of Tugurskaya and Penzhinskaya tidal power plants on the Sea of Okhotsk coast. The work analyses the expected electricity production from Tugurskaya and Penzhinskaya tidal power plants, their possibilities to supply internal and neighboring East Asian market, and evaluates their opportunities to produce hydrogen through water electrolysis. The conclusion is that these tidal power plants can generate up to 4.2 million tons of hydrogen annually that would cover a significant part of the Japan’s demand for hydrogen.

Abstract: Despite the availability of enough water in Nepal, there is difficulty in irrigation in most of the places. This is due to difficult terrain in hilly and mountainous region. Hand water pumping is possible only in terai region and grid electricity has not reached in most parts of hilly and mountainous region. For these reasons, solar water pumping from appropriate source is the best option. The main objective of this project was to design a solar powered water pumping system at Chaukune ward no 1, Surkhet district. The targeted area had water demand of 400.171 m3 per day, which was supplied from a perennial river, Budhakhola. With a distance of 732 m between the pump and reservoir, a circular reservoir of diameter 11 m, height 13 m and thickness 0.3 m was designed at an elevation of 219 m from the water surface. Solar module of rated power 87.48 kW (18 in series, 18 in parallel) was selected. The volume of storage tank is 1200.513 m3, which is sufficient to store water for 3 days. The upfront cost, operation and maintenance, replacement cost of diesel pump are about 2-4 times higher than solar photovoltaic pump. The solar pumping system does not emit greenhouse gases. Solar water pumping is found to be economically viable and environment friendly in comparison to electricity or diesel based systems for irrigation.
