Weatherwatch: how do we store surplus renewable energy?

Guardian - Renewable Energy - Fri, 12/14/2018 - 21:30

We are able to produce more renewable energy than we can use immediately. Now we must find ways to keep it stored until the demand is high

A milestone was reached for renewable energy in November when more than 100% of Scotland’s electricity demand was met by wind turbines for the first time – enough for nearly six million homes. Scottish weather is powering a revolution. With ever-larger wind turbines being built at sea, and wave and tidal power being developed, the problem will soon be how to use this surplus energy. Some is already exported to England via interconnector cables and in 2020 there will be another running from the Aberdeen area to Norway. But this will not be enough and the race is on to find ways to store cheap energy to sell back to the grid when demand is high.

Large batteries are helping, but another proven method is pump storage. This uses virtually free surplus electricity at night to pump water into upland reservoirs to be used to power turbines during peak periods. Scotland has had these schemes since the 1960s but there is potential for many more and two new ones are proposed to pump water uphill from Loch Ness to reservoirs in the hills.

Scott Morrison and the Business Council are pushing coal – but on what evidence? | Richard Denniss

Despite plummeting costs of renewables the government and the BCA insist that emissions reduction would be ‘economy wrecking’

Fresh from losing the economic fight about company tax cuts, the Coalition government is doubling down on an economic fight about renewable energy. And yet again, as they march into battle they have the Business Council of Australia as their key source of economic and political advice. What could go wrong?

The cost of renewable energy has fallen dramatically in the past 10 years and will continue to fall for years to come. By some accounts, new renewables with storage are already cheaper than coal fired power stations. Some argue that they aren’t quite there yet. But no one argues that in 30 years’ time a new coal-fired power station that has to buy coal will be able to compete with a solar farm that gets its sunshine for free.

The science of climate change indicates the economic risks posed to Australia are both materially significant and proportionally higher than for most other countries … global carbon pricing is inevitable … [and] given these economic risks, Australia needs to act to decouple energy and emissions growth from economic growth, or we will face steadily declining competitiveness as global carbon pricing and other controls increase.”

The Yellow Vests Movement Isn’t Anti-Climate Action; It’s Pro-Social Justice

Renewable Energy World - Tue, 12/11/2018 - 14:34
The Yellow Vests riots sweeping across France have grabbed headlines as governments gather in Katowice, Poland for the UN climate conference (COP24). This is the most widespread and violent protest in France since the 2005 suburban riots, and perhaps even 1968. While the unrest initially erupted as a protest against the latest rise in fuel taxes, which the government has now agreed to postpone, some are attributing the riots to a backlash against carbon taxes and climate action. This is a misguided conclusion.

Two big trends are converging in the world of power generation -- Combined Heat & Power (CHP) and biomass. CHP is gaining ground in many areas of the world due to the fact that its superior efficiency often results in major economic gains (CHP takes the waste heat from a turbine and uses it to generate steam which is often uses in district heating, or in industrial processes).
