MARKET WATCH: NYMEX, Brent crude oil prices fall modestly

August 31st, 2016

Light, sweet crude oil prices fell to settle under $47/bbl on the New York market Aug. 30 while front-month Brent crude oil prices also fell modestly to hover around $48/bbl on what analysts call uncertainty about a proposed production freeze by major producers.

Statoil to ramp up Barents Sea activity in 2017

August 31st, 2016

Statoil ASA plans to step up exploration efforts in several parts of the Barents Sea in 2017-18. The Blamann (PL849) prospect in the Goliat area, Koigen Central in PL718 on Stappen High, and the Korpfjell prospect in PL859 each hold promise for future exploration, the firm says.

RWE storage acquisition a ‘strategic fit’

August 31st, 2016

The chief executive of RWE, Peter Terium, says the pending acquisition of German solar and battery specialist Belectric Solar and Battery Holding perfectly complements the strategy the company is trying to achieve.

Both the firms have signed a share purchase deal and agreed a purchase price in a high double-digit million euro range but the deal must wait for approval from EU anti-trust authorities before completion, something the company told Power Engineering International it sees as merely a formality.

RWE Innogy CEO Terium said, “With innogy we are creating the innovative, decentralised and sustainable energy company of the future. The agreed acquisition of Belectric Solar & Battery fits this strategic orientation perfectly.”

“Smart battery storage solutions make generating electricity from renewables both more efficient and more secure. We are acquiring an innovative company that has built up an international strong market position. We are now combining our complementary strengths and creating additional impetus to successfully implement our projects in Europe and our growth regions – the whole will be greater than the sum of its parts.”

Belectric Solar & Battery designs, installs, operates and maintains utility scale photovoltaic (PV) plants. It has also been active in the field of large-scale battery storage solutions.

The company manufactures its technology products in Germany and India. It has constructed over 280 utility-scale PV plants with an installed capacity of 1.5 GW.

RWE Innogy is positioning itself to become an important contributor in the expansion and decentralisation of renewable energy system in the future. The company signposted its ambitions in grid development earlier this summer.

A decision by the EU is expected in early 2017 and Sabine Jescke, RWE spokesperson told Power Engineering International the scrutiny from Bruseels is routine practice.

“It is part of the usual process. We currently have very little industrial scale solar PV. That makes the deal so interesting for us. On the other hand Belectric is growing beyond their means so this motivates the deal for them.”

“We have a minority stake in Endesa Spain , 15 MW in Hungary, but that is it. That is why it’s interesting for us as we wish to be an international player in industrial size PV.”

“They will check (on anti-trust) it but we do not see an issue.”

EV batteries offer huge energy storage potential says BNEF

August 31st, 2016

A new report states that there is huge energy storage potential in repurposing used electric vehicle batteries.

Analysts from Bloomberg New Energy Finance believe that using these batteries could bring about a new form of low cost energy storage.

In the report, BNEF senior analyst Claire Curry calculates that there will be 29 GWh of used EV batteries coming out of cars by 2025 – a capacity that she says “far exceeds the size of the current stationary storage market”.

Of this 29 GWh, around 10 GWh will get a second life as stationary storage.EV batteries offer huge energy storage potential says BNEF

Curry states that today, a new stationary storage system can cost up to $1000/kWh while in contrast, repurposing used EV batteries could cost as little as $49/kWh in 2018, with an additional $400/kWh cost to convert to stationary use.

Curry highlights the fact that the auto industry is divided on the issue. “While Tesla won’t be involved in second life, BMW, Nissan and Mercedes Benz already have second-life stationary storage projects in place.”

The report states that this year there will be “very few used batteries available for second-life applications, but volumes will increase significantly beyond 2020. Whether these batteries are suitable for second-life storage applications depends on the energy remaining in them; whether the car company warranties them outside the vehicle; and the price of commodities.”

It notes that currently, the costs of repurposing a used EV battery, such as transportation, testing, cycling and repackaging, can be high ­– over $100/kWh today – but adds that this cost should halve by 2018 due to economies of scale and learning.

The report explains that lithium-ion batteries are the most expensive part of an electric vehicle and dictate important performance metrics like driving range and power.

“EVs currently in circulation are a maximum of five years old and the majority of batteries are performing well, with little loss of driving range (caused by energy loss of the battery).”

However, the report states that in the next few years more of these batteries will experience energy loss, and by the time they are up to ten years old they will have lost enough capacity to significantly affect the driving range.

“When battery performance drops below a threshold of acceptable performance, owners can replace the batteries with new ones or the whole car may be scrapped,” says BNEF. “Those original batteries could still have 70 per cent of their initial energy left and contain valuable materials. Landfilling them is not economic and most countries have regulations against this.”

Curry says that the development of the ‘second-life’ battery market “is interesting to car companies, policy makers, stationary storage companies, utilities, renewable power developers and battery manufactures. It offers the potential for large amounts of low cost batteries, with plenty of energy left in them, to become available years before newly manufactured unsubsidised batteries are cheap enough to deploy.”
