New hydro will help build a sustainable energy future suggests IRENA report

                                              https://www.boland-hydroturbine.com/
Hydropower capacity will need to increase 60% by 2050, with pumped hydro storage capacity needing to double, to help create a sustainable future energy system a new report from the International Renewable Energy Agency (IRENA) suggests.
Policy-makers and planners around the world need to "start thinking now" about building new hydropower projects, IRENA said in the Global Renewables Outlook report.
In the report IRENA Director-General Francesco La Camera urges stimulus and recovery packages as a response to the current Covid-19 pandemic and to “accelerate the shift to sustainable, decarbonised economies and resilient inclusive societies”. Recovery measures should include investment in “interconnected hydropower” among other technologies, La Camera says. “With the need for energy decarbonisation unchanged, such investments can safeguard against short-sighted decisions and greater accumulation of stranded assets."
The Global Renewables Outlook report says that "hydropower can bring important synergies to the energy system of the future" thanks to its multiple uses and synergies with other renewable energy technologies.
Under IRENA’s Transforming Energy Scenario, hydropower capacity will need to increase 25% by 2030, and 60% by 2050, with pumped storage doubling. When including both types of hydropower, around 850GW of newly installed capacity is required in the next 30 years – roughly the same as the entire power system capacity of the European Union in 2020.
The report continues: “Increasing hydropower capacity does not specifically entail only building new dams: options also exist to upgrade turbines and systems in existing plants, utilise run-of-river designs and electrify non-power dams.
“Yet for new hydropower plants, planners need to consider local environmental impacts, and engage in discussions with communities in the impacted areas. Hydropower plants will also need operational changes that reflect changing power system needs, including faster and more frequent ramping, and planning practices that include evaluating the impacts of climate change on water supply and reservoir storage requirements.
“Due to longer planning cycles for new hydropower dam construction, policy makers and planners need to start thinking now about new projects. For existing dams, investments are needed to modernise old hydro plants.”

Water Turbine Design for Small Scale Hydro Energy

                                                  https://www.boland-hydroturbine.com/ Selecting the Best Type of Water Turbine Design Selecting the best type of water turbine design for your particular situation often depends on the amount of head and flow rate that is available at your particular location and whether it is at the side of a river or stream, or the water is to be channelled or piped directly to your location. Other factors include whether you want an enclosed “reaction turbine design” such as the Francis turbine or an open “impulse turbine design”, such as the Pelton turbine as well as the speed of rotation of your proposed electrical generator. By analysing all of these factors together you can get some indication of what type of  Water Turbine Design  may work best for your particular situation. Knowing the difference between a Pelton and Francis turbine for example, will help make the choice easier. The following table gives a basic idea of which particul

Types of Hydropower Plants

                                                   There are three types of hydropower facilities: impoundment, diversion, and pumped storage. Some hydropower plants use dams and some do not. The images below show both types of hydropower plants. MPOUNDMENT The most common type of hydroelectric power plant is an impoundment facility. An impoundment facility, typically a large hydropower system, uses a dam to store river water in a reservoir. Water released from the reservoir flows through a turbine, spinning it, which in turn activates a generator to produce electricity. The water may be released either to meet changing electricity needs or to maintain a constant reservoir level.                                                www.boland-hydroturbine.com DIVERSION A diversion, sometimes called run-of-river, facility channels a portion of a river through a canal or penstock. It may not require the use of a dam. PUMPED STORAGE Another type of hydropower called pumped

Hydropower, the only solution for cheapest power generation

                                                 https://www.boland-hydroturbine.com/ Hydropower has the lowest life-cycle cost of any power generation technology. Hydropower is a potential life-saver for Pakistan. Yet its development has been hampered for decades. Hence, only 15 percent of Pakistan’s over 60,000MW hydropower potential has been developed in 70 years. Hydropower plants power generation can give a country economy a new path of progress. Despite initial costs and long gestation periods, hydropower plants have almost no fuel cost and have operational lives of over a century. New hydropwer plants generate electricity at Rs6-10 per unit compared to thermal power plants’ Rs15-25 per unit. All other power-generating technologies have up to 30 years of project life and need up to four times expensive plant replacements in foreign exchange. Wind and solar technologies are solely dependent on the weather. They can at best supplement but not replace hydropower which, amo
